Abstract

The invention discloses a distributing and collecting device, a microchannel heat exchanger and a heat pump air conditioner. The distributing and collecting device is provided with a plurality of flowequalizing holes which communicate with one or more branch pipes and are used for distributing and collecting a refrigerant, the refrigerant flows out or flows in through the flow equalizing holes, the number of the branch pipes, the number of the flow equalizing holes and the hydraulic diameter are arranged differently, the refrigerant flow passing through the flow equalizing holes is regulatedand controlled, and accurate control over refrigerant distribution of the distributing and collecting device is realized; according to the microchannel heat exchanger using the distributing and collecting device, the refrigerant is distributed and conveyed by the multiple branch pipes with small water conservancy diameters, so that the pressure resistance of the microchannel heat exchanger can beimproved at low cost, the refrigerant charge of the microchannel heat exchanger is further reduced, and the microchannel heat exchanger saves energy and is environmentally friendly; and the heat pumpair conditioner using the distributing and collecting device is low in cost and high in efficiency.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a manifold, a microchannel heat exchanger and a heat pump air conditioner. Background technique [0002] The micro-channel heat exchanger has a small hydraulic diameter of the refrigerant heat exchange channel and high heat exchange efficiency. The sub-collector is used for the diversion and collection of the circulating refrigerant. Due to the insufficient structural design of the sub-collector in the prior art, the structure composed of multiple parallel flow flat tubes Both evaporators and condensers have the problem of uneven refrigerant distribution to varying degrees, which affects the further improvement of heat exchange efficiency, and even limits the use of micro-channel evaporators in many applications. Contents of the invention [0003] The purpose of the present invention is to disclose a manifold, a microchannel heat exchanger and a heat pump air conditioner ...
