空気対空気熱交換器を内蔵した鉱山排気熱抽出ボックス

The built-in air-to-air heat exchanger in the mine exhaust heat extraction box is a device specifically designed to recover waste heat from mine exhaust air. Mine exhaust refers to the low-temperature, high humidity waste gas discharged from a mine, which usually contains a certain amount of heat but is traditionally discharged directly without being utilized. This device uses a built-in air-to-air heat exchanger (i.e. air-to-air heat exchanger) to transfer heat from the exhaust air to another stream of cold air, thereby achieving the goal of waste heat recovery.

動作原理
Lack of air input: The mine's lack of air is introduced into the heat extraction box through the ventilation system. The temperature of the exhaust air is generally around 20 ℃ (the specific temperature varies depending on the depth of the mine and the environment), and the humidity is relatively high.
Function of Air to Air Heat Exchanger: The built-in air to air heat exchanger usually adopts a plate or tube structure, and the exhaust air and cold air exchange heat through a partition type in the heat exchanger. The heat from the lack of wind is transferred to the cold air, while the two airflows do not mix directly.
Heat output: After being heated by heat exchange, the cold air can be used for anti freezing of mine air inlet, heating of mining area buildings, or domestic hot water, while the exhaust air is discharged at a lower temperature after releasing heat.
Characteristics and advantages
Efficient and energy-saving: Air to air heat exchangers do not require additional working fluids and directly utilize the heat transfer from air to air. They have a simple structure and low operating costs.
Environmental friendliness: By recycling exhaust heat and reducing energy waste, it meets the requirements of green and low-carbon development.
Strong adaptability: The equipment can be customized and designed according to the flow rate and temperature of the mine exhaust, suitable for mines of different scales.
Easy maintenance: Compared to heat pipe or heat pump systems, air-to-air heat exchangers have a relatively simple structure and require less maintenance.
アプリケーションシナリオ
Anti freezing at the wellhead: Use the recovered heat to heat the mine air intake and avoid freezing in winter.
Building heating: providing heating for office buildings, dormitories, etc. in the mining area.
Hot water supply: Combined with the subsequent system, provide a heat source for domestic hot water in the mining area.
precautions
Moisture treatment: Due to the high humidity of the exhaust air, the heat exchanger may face the problem of condensation water accumulation, and a drainage system or anti-corrosion materials need to be designed.
Heat transfer efficiency: The efficiency of an air-to-air heat exchanger is limited by the specific heat capacity and temperature difference of the air, and the recovered heat may not be as high as that of a heat pump system, but its advantage lies in its simple structure.

窯廃熱回収・再利用システム - ガスステンレス鋼クロスフロー熱交換器方式

The kiln waste heat recovery and reuse system aims to fully utilize the high-temperature heat in the kiln exhaust gas, and achieve a win-win situation of energy conservation and environmental protection through gas stainless steel cross flow heat exchangers. The core of this solution lies in the use of a stainless steel cross flow heat exchanger, which efficiently exchanges heat between high-temperature exhaust gas and cold air, generating hot air that can be reused.

Working principle: The exhaust gas and cold air flow in a cross flow manner inside the heat exchanger and transfer heat through the stainless steel plate wall. After releasing heat from exhaust gas, it is discharged. Cold air absorbs the heat and heats up into hot air, which is suitable for scenarios such as assisting combustion, preheating materials, or heating.

Advantages:

Efficient heat transfer: The cross flow design ensures a heat transfer efficiency of 60% -80%.
Strong durability: Stainless steel material is resistant to high temperatures and corrosion, and can adapt to complex exhaust environments.
Flexible application: Hot air can be directly fed back to the kiln or used for other processes, with significant energy savings.
System process: Kiln exhaust gas → Pre treatment (such as dust removal) → Stainless steel heat exchanger → Hot air output → Secondary utilization.

This solution is simple and reliable, with a short investment return cycle, making it an ideal choice for kiln waste heat recovery, helping enterprises reduce energy consumption and improve efficiency.

Air-to-Air Heat Recovery Exchanger

Plate heat recovery exchanger made in china

Heat exchangers are mainly made of materials such as aluminum foil, stainless steel foil, or polymers. When there is a temperature difference between the airflow isolated by aluminum foil and flowing in opposite directions, heat transfer occurs, achieving energy recovery. By using an air to air heat exchanger, the heat in the exhaust can be utilized to preheat the fresh air, thereby achieving the goal of energy conservation. The heat exchanger adopts a unique point surface combination sealed process, which has a long service life, high temperature conductivity, no permeation, and no secondary pollution caused by the permeation of exhaust gas.

Application of Cross Flow Heat Exchanger in Indirect Evaporative Cooling System of Data Center

データセンターの間接蒸発冷却システムにおけるクロスフロー熱交換器の応用

The application of cross flow heat exchangers in Indirect Evaporative Cooling (IDEC) systems in data centers is mainly reflected in efficient heat exchange, reducing energy consumption, and improving data center cooling efficiency. Here are its key roles and advantages:

  1. Basic working principle
    Cross flow heat exchanger is a type of heat exchange device whose structure allows two streams of air to cross each other while maintaining physical isolation. In indirect evaporative cooling systems in data centers, it is typically used for heat exchange between cooling air and outdoor ambient air without direct mixing.
    The workflow is as follows:
    The primary air (data center return air) exchanges heat with the secondary air (external ambient air) through one side of the heat exchanger.
    The secondary air evaporates and cools in the humidification section, reducing its own temperature, and then absorbs heat in the heat exchanger to cool the primary air.
    After the primary air is cooled down, it is sent back to the data center to cool down the IT equipment.
    The secondary air is ultimately discharged outdoors without entering the interior of the data center, thus avoiding the risk of pollution.

  2. Advantages in Data Centers
    (1) Efficient and energy-saving, reducing cooling demand
    Reduce cooling load: By using cross flow heat exchangers, data centers can utilize external air cooling instead of relying on traditional mechanical refrigeration (such as compressors).
    Improve PUE (Power Usage Effectiveness): Reduce the operating time of mechanical cooling equipment, lower energy consumption, and make PUE values closer to the ideal state (below 1.2).
    (2) Completely physically isolated to avoid contamination
    Cross flow heat exchangers can ensure that outdoor air does not come into direct contact with the air inside the data center, avoiding pollution, dust, or humidity affecting IT equipment. They are suitable for data centers with high air quality requirements.
    (3) Suitable for various climatic conditions
    In dry or warm climates, indirect evaporative cooling systems are particularly effective and can significantly reduce the cooling costs of data centers.
    Even in areas with high humidity, optimizing the design of heat exchangers can improve heat exchange efficiency.
    (4) Reduce water resource consumption
    Compared to direct evaporative cooling (DEC), indirect evaporative cooling does not require direct spraying of water into the air of the data center, but rather indirect cooling through a heat exchanger, thus reducing water loss.

  3. Applicable scenarios
    Cross flow heat exchangers are widely used in the following types of data centers:
    Hyperscale Data Center: Requires efficient and energy-saving cooling solutions to reduce operating costs.
    Cloud computing data center: requires high PUE values and seeks more sustainable cooling methods.
    Edge Data Center: typically located in harsh environments, requiring efficient and low maintenance cooling systems.

  4. Challenge and Optimization Plan
    Heat exchanger size and efficiency: Larger cross flow heat exchangers can improve heat exchange efficiency, but they also increase the footprint, so optimization design is needed, such as using aluminum or composite material heat exchangers to improve heat exchange efficiency.
    Scaling and maintenance: Due to humidity changes, heat exchangers may experience scaling issues, requiring regular cleaning and the use of corrosion-resistant coatings to extend their lifespan.
    Control system optimization: Combined with intelligent control, dynamically adjust the working mode of the heat exchanger based on external environmental temperature, humidity, and data center load conditions to improve system adaptability.

  5. Future Development Trends
    New efficient heat exchange materials, such as nano coated heat exchangers, further improve heat exchange efficiency.
    Combined with AI intelligent control system, dynamically adjust the heat exchange according to the real-time load of the data center.
    Combining liquid cooling technology to further improve heat dissipation efficiency in high-density server rooms.

Cross flow heat exchangers play an important role in the indirect evaporative cooling system of data centers, providing efficient heat transfer, reducing energy consumption, minimizing pollution, and improving equipment reliability. They are currently one of the important technologies in the field of data center cooling, especially suitable for large-scale, high-efficiency data centers.

商業用換気とエネルギー回収

適切な室内空気質（IAQ）には、地域の状況や気候に応じて多くの要因が関係します。呼吸障害などの健康問題は、ほこり、花粉、その他の汚染物質を含む空気によって発生する可能性があります。劣悪な室内環境は建物に損傷を与える可能性もあります。

商業用（非住宅用）の空調ユニットは、オフィス、ホテル、空港などの建物向けに設計された大型のユニットになる傾向があります。課題は、できるだけ少ないエネルギー入力で快適な IAQ を実現することです。つまり、圧力降下は低く（必要なファン電力は少なくなる）、熱/湿度効率は高く（暖房/冷房/湿度制御に消費されるエネルギーは少なくなる）必要があります。

地理的な地域に応じて、熱交換器の主な目的は、建物に入る前の屋外の空気を加熱するか、冷却するか（場合によっては除湿するか）の間で変わります。

空調ユニット（AHU）は換気システムの中心にあります。少なくとも、AHU にはユニットを通して空気を移動させるための 1 つまたは複数のファンが各空気チャネルに含まれています。両側のフィルターはほこりや花粉などを除去し、ファンを保護します。最後に、熱交換器が必要な熱または湿度を排気から給気へ伝達します。

空気対空気熱交換器を実装することは、通常廃熱と考えられるものを利用する優れた方法です。空気対空気熱交換器は、給気と排気の温度差を利用してシステムの効率を高めます。空気対空気熱交換器には、ロータリー式熱交換器とプレート式熱交換器の 2 種類があります。

タイプと正確な構成は用途によって異なります。どちらのタイプも、効率的な熱伝達能力や非常に長い耐用年数などの優れた特性を持つアルミニウムで作られています。当社では、各製品に多数の設計変数とオプションを提供しており、あらゆる AHU に完璧にフィットし、パフォーマンスを発揮します。

データセンターにおける間接冷却

現代のデータ センターは技術的に非常に複雑であり、安全かつ効率的に稼働し続けるためには、継続的な綿密な監視と管理が必要です。

適切な温度を維持することは、データセンター管理者にとって最も重要な課題の一つです。データセンター内の温度と湿度が過度に上昇すると、結露が発生し、内部の機器に損傷を与える可能性があります。これは甚大な損害と混乱を引き起こす可能性があるため、何としても回避しなければなりません。幸いなことに、データセンターの温度を適切なレベルに保つための様々なテクノロジーが利用可能です。

データセンターの冷却方法は数多くあります。間接空冷は外気を利用しますが、空気対空気熱交換器を組み込むことで、外気を別のループに保持し、サーバールームに空気が入ることなく冷却を実現します。

間接冷却方式の利点は、屋外の大気汚染物質や湿気によって室内空気が汚染されないことです。熱交換器がデータセンター建物の内外の空気の流れを分離し、熱を建物内から外へ伝達します。そのため、外気と室内空気が混ざることはありません。

データセンターが常に低温の地域にある場合、通常は乾式冷却で十分です。つまり、水は不要です。しかし、熱交換器の外気側に水を噴霧することで蒸発効果が得られ、室内温度が低下します。この方法は間接蒸発冷却（IEC）と呼ばれます。

温暖で乾燥した気候に最適なIECは、優れた冷却能力を備えながら、運用コストと初期コストを抑えます。夏季には、周囲温度が6～8℃（10～15°F）低下するのが一般的です。IECは、従来のフリークーリングと比較して最大28%、空冷式フリークーリングの代替システムと比較して最大52%のエネルギーを節約します。

蒸発冷却には、高い効率と低い圧力損失を両立し、堅牢な耐腐食性と信頼性の高い水密性を備えたプレート式熱交換器が必要です。クロスフロー熱交換器は、これらの要件をすべて満たし、優れた冷却能力を提供します。

当社のクロスフロー熱交換器、特に蒸発冷却技術は、従来の冷却方法に代わる効率的で低コスト、かつ環境に優しい代替手段を提供します。
