Abstract

The invention provides a micro-channel heat exchanger assembly, a micro-channel heat exchanger and an air conditioning system. The micro-channel heat exchanger assembly comprises at least one flow collecting pipe, flat pipes and at least one flow divider. An outlet of the flow divider is communicated with inlets of the flat pipes, and outlets of the flat pipes are communicated with the flow collecting pipe. According to the micro-channel heat exchanger, at least one flow divider is adopted for flow dividing, so that the whole fluid enters the flat pipes in a uniformly-dispersed mode and then is collected to the flow collecting pipes to be discharged, and the problem of uneven flow dividing of the micro-channel heat exchanger is solved. By using the flow divider, the heat exchanger is uniform in flow division, heat exchange can be optimized, and the performance of the heat exchanger can be fully exerted.

Description

technical field [0001] The application belongs to the technical field of air conditioning systems, and in particular relates to a microchannel heat exchanger assembly, a microchannel heat exchanger and an air conditioning system. Background technique [0002] The existing microchannel heat exchanger consists of two headers, a plurality of flat tubes and fins, and the headers are generally placed vertically. When the micro-channel heat exchanger is used as an evaporator, the two-phase refrigerant enters from the lower part of the header. Due to the influence of gravity and flow pattern, the distribution of liquid refrigerant is uneven. In the same process, the lower flat tube is relatively more liquid refrigerant, and the upper flat tube is relatively large. There is relatively little or no liquid refrigerant, which leads to the inability of the microchannel heat exchanger to fully exert its performance, which restricts the heating performance of the whole machine. [0003] ...
