Problems solved by technology
However, the liquid receiver of this structure has obvious defects due to the welding of the head and the shell: First, there is a problem of sealing after welding. Under the influence of high welding temperature, the refrigerant inlet and refrigerant outlet will It causes deformation, which affects the sealing effect of the connection between the inlet and outlet and the outside (such as a briquette), and the welding cost is relatively high; secondly, the filter made of non-metallic material inside the liquid reservoir will also shrink and deform due to high temperature. Affect the filtration accuracy of the liquid reservoir, resulting in impurities with relatively large particles easily permeating the filter and entering into other components of the air conditioning system, causing pollution and increasing the wear and tear of components, and may even be blocked, affecting the normal operation of the air conditioning system

Embodiment Construction
[0029] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0030] Please refer to Figure 1 to Figure 3 , figure 1 It is a schematic structural diagram of a specific embodiment of the reservoir provided by the present invention, figure 2 for figure 1 The cross-sectional schematic diagram of the middle head, image 3 for figure 1 A schematic cross-sectional view of the middle shell without processing. The reservoir in this embodiment includes a housing 2 with one end closed and one end open, a filter assembly arranged in the housing, and a head 1 mounted on the open end of the housing 2. The housing 2 of the reservoir is roughly open at one end. Cylindrical structure, it should be understood that the reservoir housing 2 includes but is not limited to a cylindrical shape, and structure...

A liquid receiver comprises a shell, a filter assembly and a sealing head. One end of the shell is closed, and the other end of the shell is open; the filter assembly is arranged in the shell, and thesealing head is mounted at the open end of the shell; the sealing head is provided with a first connector and a second connector, and the sealing head comprises a circumferential wall part; the circumferential wall part is in clearance fit with at least one part of the open end of the shell; the sealing head further comprises at least one annular sunken part which is sunken in the circumferentialwall part; an annular boss part is formed in the position, corresponding to the annular sunken part of the sealing head, of the inner wall of the shell through a cold extruding rolling groove; and the annular boss part and the annular sunken part are embedded mutually. According to the liquid receiver, the structure is simple, the cost is low, filtration performance is high, and the service lifeof the liquid receiver can be prolonged.
Description
Technical field [0001] The present invention relates to the technical field of refrigeration systems, in particular to a liquid accumulator. The invention also relates to a manufacturing method having the above liquid accumulator. Background technique [0002] The liquid receiver is an important accessory in the refrigeration system. Its function is to filter the impurities in the refrigerant, absorb the moisture in the refrigerant and store a certain amount of refrigerant. In the prior art, the liquid reservoir includes a head and a shell welded to the head, and the two are welded to form a closed container except for the inlet of the refrigerant and the outlet of the refrigerant. However, the liquid reservoir of this structure has obvious defects due to the welding of the head and the shell. First, there is a problem of sealing after welding. Under the influence of welding high temperature, the refrigerant inlet and the refrigerant outlet will be affected by the high temperatur...
