Several types of air waste heat recovery heat exchangers

There are several types of air waste heat recovery heat exchangers:

1. Plate heat exchanger: This type of heat exchanger uses a series of metal plates to transfer heat between two fluids. The plates are arranged in a way that allows the fluids to flow in opposite directions, maximizing heat transfer efficiency.
2. Shell and tube heat exchanger: This type of heat exchanger consists of a series of tubes inside a larger shell. One fluid flows through the tubes while the other flows around the tubes in the shell. Heat is transferred between the two fluids through the tube walls.
3. Heat pipe heat exchanger: This type of heat exchanger uses a sealed pipe filled with a working fluid that evaporates and condenses to transfer heat between two fluids. The working fluid absorbs heat from one fluid, evaporates, and then condenses to release the heat to the other fluid.
4. Run-around coil heat exchanger: This type of heat exchanger uses two separate coils, one in each fluid stream, connected by a pump and a heat exchanger. Heat is transferred between the two fluids as they flow through their respective coils and the heat exchanger.
5. Rotary heat exchanger: This type of heat exchanger uses a rotating wheel with a heat-absorbing material to transfer heat between two fluids. One fluid flows through the wheel while the other flows around the wheel. Heat is transferred between the two fluids as the wheel rotates.
