Abstract

The invention relates to a refrigerating fluid flow distributing structure, a micro-channel flow distributing assembly, a heat exchanger and an air-conditioner. The refrigerating fluid flow distributing structure comprises a cylinder, and the cylinder is provided with flow distributing cavities, a refrigerating fluid inlet and flow distributing channels. The flow distributing channels are groove-shaped flow channels which are formed along the outer surface of the cylinder. The refrigerating fluid inlet and each flow distributing cavity are communicated through fluid via the corresponding groove-shaped flow channel. The amount of refrigerating fluid entering the flow distributing cavities can be controlled, a condition is provided for accurately controlling the distribution amount of the refrigerating fluid, the height of the entire flow distributing structure cannot be affected, and the applied range is wider.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a refrigerant distribution structure, a microchannel distribution assembly, a heat exchanger and an air conditioner. Background technique [0002] Due to its high heat transfer efficiency, microchannel heat exchangers are gradually being used more and more widely in air-conditioning systems. flat tube connection. When a microchannel heat exchanger works as a heat exchanger, such as a condenser, the refrigerant used to conduct heat or cold needs to be distributed from the inner cavity of the header through the distribution structure (ie, "distributor") to the manifold connected to the header. in multiple flat tubes. However, the above-mentioned distribution process often has the problem of difficult refrigerant distribution, which easily leads to a certain degree of limitation in the heat exchange application of the micro-channel heat exchanger. For this problem, the e...
