Embodiment 1

[0024] The connection structure of the cooling system of the refrigeration device in this embodiment, combined with figure 2 , including a liquid receiver, a liquid separator and a compressor. The liquid separator includes an air inlet pipe 1, an upper end cover 2, a middle cylinder body 3, a lower end cover 4 and an air outlet pipe 5. The air outlet pipe 5 of the liquid separator is pressed by an interference fit. Into the cylinder hole 8 of the compressor, the first flange 6 is set between the air outlet pipe 5 and the compressor shell 9, and the first flange 6 is connected with the compressor shell 9 and the air outlet pipe 5 by welding. Among them, interference fit In this embodiment, the outer diameter of the air outlet pipe 5 is 0.005mm up and down the inner diameter of the cylinder bore 8 (that is, if the inner diameter of the cylinder bore 8 is 20mm, the air outlet pipe 5 should be precisely shaped so that the air outlet pipe 5 The outer diameter of the end facing the...

Embodiment 2

Abstract

The invention relates to a connection structure of a cooling system of a refrigerating plant, in particular to the technical field of connection relations among liquid reservoirs and liquid dispensers and among the liquid dispensers and compressors of air-conditioning cooling systems. The connection structure comprises a liquid reservoir, a liquid dispenser and a compressor. The liquid dispenser comprises an air inlet tube, an upper end cover, a middle barrel, a lower end cover and an air outlet tube, the air outlet tube of the liquid dispenser is pressed into a cylinder hole of the compressor in an interference fit manner, and a first flange is sleeved between the air outlet tube and a shell of the compressor and is connected with the shell of the compressor and the air outlet tube by means of welding. According to the technical scheme, the connection structure has the advantages of convenience in machining, simple structure and the like.

Description

technical field [0001] The invention relates to a connection structure of a cooling system of a refrigeration device, in particular to the technical field of the connection relationship between a liquid receiver and a liquid separator, and a liquid separator and a compressor in an air-conditioning cooling system. Background technique [0002] The cooling system of refrigeration devices such as air conditioners is mainly composed of liquid receivers, liquid separators and compressors connected in sequence. figure 1 , the liquid separator is mainly composed of an upper end cover 2a, a middle cylinder body 3a and a lower end cover 4a. During installation, the upper end cover 2a is connected to the liquid reservoir through the inlet pipe 1a, and the lower end cover 4a is passed through the outlet pipe 5a (also called is "reservoir elbow 5a") connected to the compressor cylinder hole 8a, after the intake pipe 1a, upper end cover 2a, middle cylinder 3a, lower end cover 4a, air out...
