Abstract

The invention discloses a collecting pipe and a heat exchanger with the collecting pipe. The collecting pipe comprises a pipe body, a refrigerant cavity is formed inside the pipe body, the pipe wall of the pipe body is provided with multiple flat pipe grooves formed in the axial direction of the pipe body at intervals, a throttling portion is arranged between every two adjacent flat pipe grooves and located in the refrigerant cavity, and the cross sectional area of each throttling portion is smaller than that of the other part of the refrigerant cavity. According to the collecting pipe in theembodiment, refrigerants flowing into flat pipes tend to be uniform, and then the heat exchange effect of the heat exchanger is improved.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a header and a heat exchanger with the header. Background technique [0002] Parallel flow heat exchangers such as microchannel heat exchangers have been widely used due to their high heat transfer efficiency, small size, light weight, and strong pressure resistance. Microchannel heat exchangers mainly include flat tubes with microchannels, fins and headers. Both ends of the flat tubes are inserted into headers for distributing and collecting refrigerant. Fins are arranged between adjacent flat tubes to enhance the heat exchange efficiency between the heat exchanger and the air side. [0003] When the heat exchanger is used as an evaporator, for a microchannel heat exchanger including a plurality of flat tubes, there is a problem of uneven distribution of inlet refrigerant, which leads to a decrease in the operating performance of the heat exchanger. Contents of the i...
