Abstract

The invention provides a flat pipe and a heat exchanger. The flat pipe is provided with a micro-channel, wherein the two ends of the micro-channel in the extending direction of the micro-channel are located on the two end faces of the flat pipe correspondingly, and connecting holes communicating with the micro-channel are formed in the peripheral wall of the flat pipe. On one hand, by increasing the area of the holes for refrigerant circulation in the flat pipe, the capillary phenomenon is weakened, and the probability that the micro-channel is blocked by welding flux is reduced; and on the other hand, due to the fact that the path for a refrigerant to enter the micro-channel is increased, the difficulty that the micro-channel is completely blocked is increased, the micro-channel is not prone to be completely blocked by the welding flux, the amount of the refrigerant flowing in the flat pipe is not prone to be reduced, the probability that the micro-channel in the flat pipe can work normally is greatly increased, the heat exchange efficiency is high, and the refrigerating or heating effect is good.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a flat tube and a heat exchanger. Background technique [0002] The microchannel heat exchanger includes two headers, flat tubes connecting the two headers and fins arranged between the flat tubes, and the two ends of the flat tubes are plugged into the two headers respectively. The flat tube is provided with microchannels for refrigerant to pass through. Its working principle is: the refrigerant enters the collecting pipe through the inlet end of a collecting pipe, then enters the microchannel of the flat tube through the collecting pipe, and then enters another collecting pipe from the microchannel. In the process of flowing in the flat tube, the refrigerant exchanges heat with external air and other media, thereby realizing cooling or heating. [0003] After research, it is found that the existing heat exchanger has the following disadvantages: [0004] The heat excha...
