Heat pipe waste heat recovery performance characteristics:

- Jun 07, 2017 -

The heat pipe is a heat transfer element with high heat transfer performance. It is through the closed vacuum tube liquid phase transition heat transfer, the internal thermal resistance is small, with good isothermal performance characteristics, specifically in:

1, heat pipe heat transfer efficiency, small size

Heat pipe in addition to heat transfer by the phase change, the heat pipe heat exchanger on both sides of the ribs, enhanced heat transfer. The same heat load, the number of tubes can be reduced, the flow area can be expanded, the flow rate can be reduced, greatly reduce the wear and improve the life of the heat exchanger heat pipe heat exchanger hot and cold fluid with pure counter-current arrangement, flue gas, Communication room high thermal coefficient, small size, light weight, easy to arrange.

2, heat pipe heat exchanger has a good anti-corrosion ability

As the heat transfer within the tube through the liquid phase change, the wall temperature is high, the isothermal performance is good, the design of the wall temperature to avoid the flue gas dew point temperature, flushing heat pipe will not dew, flue gas will not overflow , But with the flue gas discharge, so heat pipe, tube box and pipe will not be corroded.

3, heat pipe heat exchanger has a strong anti-fouling, blocking ash capacity

Due to avoid the smoke dew point, so that dust is not easy to stick in the fins and wall. Designed to adjust the proportion of good flue gas and air side, adjust the flow rate, can be conducive to self-cleaning. At the same time heat pipe in the heat will produce self-vibration, so that the ash is not easy to adhere to the tube wall and fins, which will not block ash.

4, long service life

Heat pipe waste heat recovery unit life of more than 10 years, a single heat pipe failure does not affect the heat recovery machine work, heat pipe can be replaced.

Many of the above advantages are ordinary pipe heat exchanger can not match, so its life is generally three times the ordinary heat exchanger.
