Main Features of Heat Exchanger

The heat pipe is a heat transfer component with high thermal conductivity. It transfers heat through the evaporation and condensation of the working fluid in the fully enclosed vacuum tube shell. It has extremely high thermal conductivity, good isothermal performance, and heat transfer between the hot and cold sides. It has a series of advantages such as the area can be changed arbitrarily, long-distance heat transfer, and temperature control. Next, I will introduce the main features of the heat pipe heat exchanger, hoping to be helpful to friends who are about to purchase heat pipe heat exchangers.

1. The heat pipe heat exchanger can completely separate the hot and cold fluids through the middle partition of the heat exchanger. During operation, when a single heat pipe is damaged due to wear, corrosion, over-temperature and other reasons, it basically does not affect the operation of the heat exchanger. The heat pipe heat exchanger has high reliability for heat exchange occasions of flammable, explosive and corrosive fluids.

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

3. For fluids with high dust content, the heat pipe heat exchanger can solve the wear and dust blocking problems of the heat exchanger by changing the structure and expanding the heating surface.

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