How Finned Tubes Conduct Heat

The plate-fin tube heat exchanger is a common form of heat exchanger used at this stage, in which the water pipe is made of air conditioning copper pipe, and the plate-fin type is made of aluminum block. Most of the evaporator and cooler of household air conditioners are plate-fin tube heat exchangers, and the production capacity of this type of heat exchanger is tens of millions. At this stage, the key research progress of plate-fin tubular heat exchanger is compact, that is, small tubes are selected to pass through air conditioning copper tubes.
At this stage, the finned tube heat exchanger has been tested for its thermal conductivity in ultra-low temperature natural environment, and the vaporization experiment has been carried out on the finned tube air conditioning evaporator. According to the continuous measurement of the temperature of several different parts of the finned tube air conditioning evaporator, different temperature curves have been obtained. The curve analysis shows that the three regions of the vapor-liquid two-phase and the heat-conducting vapor phase have been carried out, and the test results are the sections of similar heat exchangers, The design scheme shows the basic and obtains the relationship between water flow and thermal conductivity.
