Description

Collecting pipe assembly and heat exchanger

Technical Field

The utility model relates to a heat exchanger technical field especially relates to a pressure manifold subassembly and heat exchanger.

Background

The heat exchanger is used as a device for heat exchange and is widely applied to the industries of automobiles, chemical engineering, food and the like. Generally, a partition plate can be arranged in a collecting pipe of the heat exchanger to force a refrigerant to change the flowing direction in a flat pipe, so that the flow of the refrigerant is increased, and the heat exchange effect of the heat exchanger is improved.

As shown in fig. 1-3, a conventional method for installing a partition plate 2 'in a header 1' of a heat exchanger is to insert the partition plate 2 'into the header 1' from a side of the header 1 'not provided with a flat tube groove 3', and insert the partition plate 2 'into an inner cavity of the header 1' and abut against a wall surface of the inner cavity of the header 1 'at the side provided with the flat tube groove 3'. Because the flat tube grooves 3 ' of the collecting pipe 1 ' are formed by stamping the collecting pipe 1 ', not only the pipe wall of the collecting pipe 1 ' is deformed during stamping, but also the stamping die is abraded along with the increase of the use frequency, so that the deformation of the pipe wall of the collecting pipe 1 ' is further increased.

As shown in fig. 4-6, the deformation of the pipe wall of the collecting pipe 1 ' may cause irregular deformation of the inner cavity of the collecting pipe, so that after the partition plate 2 ' is assembled into the inner cavity of the collecting pipe 1 ', a leakage gap 4 ' may exist between the partition plate 2 ' and the inner cavity of the collecting pipe 1 ', causing the refrigerant of the collecting pipe 1 ' to leak inwards and outwards. This not only seriously influences the function and quality of the collecting pipe 1', reduces the heat exchange effect of the heat exchanger, but also increases unnecessary reworking, even leads to product scrapping and increases the production cost.
