Heat pipe heat exchanger The heat pipe in is a heat transfer element, and its heat conduction capacity is hundreds to thousands of times higher than that of metal. The heat pipe also has the characteristics of good temperature equalization, adjustable heat flux, reversible heat transfer direction and so on. The heat pipe heat exchanger formed with it not only has the inherent characteristics of large heat transfer, small temperature difference, light weight, small volume, rapid thermal response, etc. of the heat pipe, but also has the characteristics of convenient installation, simple maintenance, long service life, small resistance loss, easy separation of air inlet and exhaust passages, and no leakage between each other.

Structural performance:

1. The heat pipe heat exchanger can completely separate the cold and hot fluid through the middle plate of the heat exchanger. When a single heat pipe is damaged due to wear, corrosion, overheating and other reasons during operation, the operation of the heat exchanger is basically not affected. The heat pipe heat exchanger has high reliability when used in natural, explosive and highly corrosive fluid heat exchange occasions.

2. The cold and hot fluids of the heat pipe heat exchanger flow separately, which can easily realize the countercurrent heat transfer of the cold and hot fluids. Both cold and hot fluids flow outside the pipe. Because the heat transfer coefficient of the flow outside the pipe is far higher than that of the flow inside the pipe, it is very economical to use it in the low grade heat recovery occasions.

3. For the fluid with high dust content, the heat pipe heat exchanger can solve the problem of wear and ash blockage of the heat exchanger by changing the structure and expanding the heating surface.

4. When the heat pipe heat exchanger is used to recover the waste heat of corrosive flue gas, the heat pipe wall temperature can be adjusted by adjusting the heat transfer area of the evaporation section and the condensation section, so that the heat pipe can avoid large corrosion areas as much as possible.
