Description

Collector and collecting tray thereof

Technical Field

The utility model relates to a heat exchanger field especially relates to a collector and catch tray thereof.

Background

The air conditioner heat exchanger mostly adopts a multi-flow heat exchanger, because if a single flow is adopted, the pressure drop along the pipeline direction is increased along with the extension of the pipeline, and then the heat exchange efficiency is reduced, so that in the prior art, the multi-flow heat exchanger is mostly adopted to reduce the pressure drop along the flow of the refrigerant in the heat exchange pipe, and the air conditioner energy efficiency is improved. The multi-flow heat exchanger needs to be provided with a distributor for uniformly distributing media to each heat exchange tube, and a collector for collecting and sending out the media in each heat exchange tube. The existing collector and distributor are manufactured in a machining mode after being integrally formed, so that the processing difficulty is high; and the current collector and distributor are mostly made of red copper or brass materials, so the manufacturing cost is higher.

In addition, there are two types of installation methods for the collector and the distributor: 1, directly welding the collector and the distributor on an end plate of the heat exchanger, but in this way, the materials of the end plate, the collector and the distributor and the welding difficulty of the collector, the distributor and the copper pipe and the end plate are considered. 2, the collector is screwed and fixed on the end plate through a screwing component, and the collector fixing structure suitable for the shell-and-tube heat exchanger can be referred to in Chinese utility model patent document with publication number "CN 203731927U"; however, compared with welding, the solution is complicated in structure, has more parts and has the risk of sealing leakage.
