The invention discloses a flow collecting structure, a micro-channel heat exchanger and an air conditioner. The flow collecting structure comprises a base plate, and a plurality of channels are formed in the plate face of one side of the base plate and used for inserting-connecting positioning with heat exchange pieces; and a fluid channel is arranged in the base plate and communicates with the channels, and the fluid channel is arranged to collect fluid in the channels and lead the fluid out of a flow collecting structure body or distribute the fluid flowing into the flow collecting structure body and lead the fluid into the channels. The micro-channel heat exchanger comprises the heat exchange pieces and further comprises the two flow collecting structures, the two flow collecting structures are arranged at the two ends of the heat exchange pieces respectively, and the ends of the heat exchange pieces are inserted into the channels so as to communicate the channels with pipelines in the heat exchange pieces. The air conditioner comprises the micro-channel heat exchanger. According to the technical scheme, the technical problem that a flow collecting structure is easy to damage due to densely arranged channels in the prior art is solved.
Description
technical field [0001] The invention relates to the field of electrical equipment, in particular to a current collecting structure, a microchannel heat exchanger and an air conditioner. Background technique [0002] Air-conditioning heat exchangers have experienced traditional tube-fin heat exchangers and new micro-channel heat exchangers. With the increasing demand for high-energy-efficiency and environmentally-friendly air-conditioning, the development of next-generation air-conditioning heat exchangers to ultra-fine tube diameters is a important direction. At present, the mass-produced microchannel heat exchangers have multiple flat tubes (heat exchange fins), and there are many fine flow channels in them, and there are collecting and dividing collecting tubes at both ends of the flat tube . The header is usually a large round tube, and grooves are set on the side of the tube for the insertion of flat tubes (heat exchange fins). The ends of the flat tubes are directly i...
