Abstract

The invention provides a heat exchange tube and an air conditioner. The heat exchange tube comprises a tube body and fins arranged on the outer surface of the tube body. Channels are formed between the adjacent fins. Communication grooves are formed in the fins to enable the adjacent channels to communicate, and the communication grooves are used for circulating refrigerants. By utilizing the technical scheme, the adjacent channels can communicate through the communication grooves formed in the fins, the area of discharging channels for condensed liquid refrigerants is increased, the refrigerant discharging capacity is enhanced, and the refrigerants can better circulate on the surface of the heat exchange tube. Therefore, the situation that the thickness of the liquid refrigerants on the surface of the heat exchange tube is increased too much, and consequently heat resistance is increased and heat exchange efficiency is lowered can be avoided.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a heat exchange tube and an air conditioner. Background technique [0002] In the air conditioning and refrigeration industry, water-cooled condensers have developed rapidly due to their compact structure and wide applicability. High efficiency, energy saving and replacement of new refrigerants are still the main research directions at present. Most of the water-cooled heat exchangers are horizontal shell-and-tube heat exchangers, with freon in the shell and water in the tube. In the condenser, a factor that has a relatively large impact on its heat transfer is the performance of the heat transfer tubes in the shell. Inside the shell side, the refrigerant on the outside of the condenser tube undergoes a phase change to perform heat exchange. The refrigerant condenses outside the tube to form a liquid film covering the surface of the heat exchange tube. The existence of th...
