Liquid blocking structure, heat exchanger and air conditioner

Abstract

The invention discloses a liquid blocking structure, a heat exchanger and an air conditioner. The structure comprises a shell and an inner shell which is arranged in the shell and used for covering a heat exchange coil pipe, an air channel area is formed in a gap between the shell and the inner shell, a refrigerant outlet is formed in the upper portion, corresponding to the air channel area, of the shell, and a liquid blocking assembly is arranged in the air channel area. The multi-layer inner coil pipe type heat exchange pipe is adopted, the falling film area heat exchange pipe is covered with the barrel, an annular space is formed between the barrel and the shell, a gaseous refrigerant is discharged upwards from the peripheral annular area, the liquid blocking structure and the filter screen device are arranged between the inner shell and the shell, when gas flows upwards, the liquid blocking device is impacted through inertia, splashing liquid drops are separated out, and the liquid drops flow into the flooded area under the action of gravity, so that the compressor is prevented from sucking air and carrying liquid, the heat exchange performance of the unit is enhanced, and the refrigerant filling amount can be saved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a liquid blocking structure, a heat exchanger and an air conditioner. Background technique [0002] With the continuous progress of society, the demand for commercial air conditioners is increasing. At the same time, the needs of users are diverse, and there are high requirements for the performance, size, quality and cost of heat exchangers. At present, there are some common problems in the compact heat exchangers on the market. The most important one is that the flow field of the gaseous refrigerant is turbulent, which is easy to cause the phenomenon of liquid in the suction of the compressor, which in turn leads to the low heat exchange efficiency of the heat exchanger and the poor performance of the unit. ideal. SUMMARY OF THE INVENTION [0003] In order to solve the above-mentioned technical problem of the air-conditioning system in the prior art, the present inv...

Problems solved by technology

There are some common problems in the compact heat exchangers currently on the market, the most important of which is the disordered flow field of the gaseous refrigerant, which is likely to cause the phenomenon of liquid in the suction of the compressor, which in turn leads to the low heat transfer efficiency of the heat exchanger and the poor performance of the unit. ideal
