What Is A Heat Pipe Heat Exchangers?
Jan 04, 2018

Heat pipe heat exchangers

The superconductivity and isothermal of heat pipe make it an ideal tool for controlling temperature in aerospace technology. Heat pipe heat exchangers are widely used because of their advantages of high heat transfer efficiency, compact structure, small pressure loss, and control of dew point corrosion. Used in metallurgy, chemical industry, oil 

refining, boilers, ceramics, transportation, textile, machinery, electronics and other industries.

The heat pipe transfers heat by evaporating and condensing the working fluid in the totally enclosed vacuum tube shell, it's advantages is that has extremely high thermal conductivity and good isothermal property, the heat transfer area on both sides can be changed arbitrarily, and the heat transfer can be controlled at a long distance. 

The disadvantage is anti-oxidation, high temperature performance is poor. 

This shortcoming can be solved by installing a set of ceramic heat exchanger on the front part. The ceramic heat exchanger solves the problem of high temperature resistance and corrosion resistance.

Heat pipe evaporation section of the working fluid will boil or evaporated to absorb heat from the external heat source to produce latent heat of vaporization, medium change from the liquid into steam, the resulting steam in the tube under the pressure of a certain role, flow to the condensing section, the steam encountered cold wall and the external cold source condenses into a liquid and releases latent heat of vaporization at the same time, and is transmitted to the external cold source through the pipe wall. 

The condensate is returned to the evaporation section under the action of gravity (or wick) to evaporate again. So reciprocate, to achieve the external heat transfer and exchange of heat between the two medium
