The invention discloses a micro channel heat exchanger for a heat pump system. The heat exchanger comprises an upper part head tube, a lower part head tube and a plurality of separated parallel flat tubes for communicating the upper part head tube with the lower part head tube, wherein a plurality of fins are arranged on each flat tube; the heat exchanger is divided into a first plane and a second plane; a drainage baffle sheet clamped on the external surface of each flat tube is arranged between the upper part head tube and the lower part head tube; one side of each drainage baffle sheet is provided with a first edge higher than the first plane of the heat exchanger, and the other side of each drainage baffle sheet is provided with a second edge higher than the second plane of the heat exchanger; and the second edges and the first edges are oppositely distributed. The drainage baffle sheets can effectively discharge water drops converged on the flat tubes and the fins, so that the discharge of the water drops on the surfaces of the flat tubes and the fins is improved, air flow is increased, the heat exchange efficiency of the heat pump system is improved, and the aims of high efficiency and energy conservation are fulfilled.
Description
technical field [0001] The invention relates to a cold and heat exchange technology for an air conditioner, in particular to a microchannel heat exchanger used by an air conditioner heat pump. Background technique [0002] At present, the refrigeration system and heating system of the air conditioner are carried out by the heat pump system, and the heat pump in the heat pump system is a mechanical device that can transfer heat from a low-temperature heat source to a high-temperature heat source. For example, in winter, outdoor air, surface water, groundwater, etc. are low-temperature heat sources, while indoor air is a high-temperature heat source. The function of the heat pump air conditioner is to transfer the heat from the outdoor environment to the indoor environment. [0003] refer to figure 1 As shown, it shows a schematic diagram of the heating cycle of a heat pump system in the prior art; the heat pump system includes: an evaporator 101, a compressor 102, a condense...
