Liquid reservoir

Abstract

The invention relates to a liquid reservoir, which comprises a container, an end plate, an extraction tube and a drying part, wherein the container consists of bottom cylindrical parts; the end plate is provided with a refrigerant inlet and a refrigerant outlet; the extraction tube is kept pendent from the end plate used for blocking the upper ends of the cylindrical parts and is arranged at a slightly central position of the container; the drying part is arranged outside the extraction tube; the upper end of the extraction tube is connected with the refrigerant outlet; a liquid refrigerant retained at the bottom of the lower end of the container from the lower end of the extraction tube flows out through the refrigerant outlet; and the container consisting of the cylindrical parts comprises a corrugated part which is formed on the lower part of the container. By the liquid reservoir, the bottom of the lower end of the container is formed by the corrugated part, so automobile vibration and other load influences or impact influence brought by change of high-pressure refrigerant pressure can be absorbed through the corrugated part, and stable operation of the liquid reservoir can be maintained; and moreover, resonance of a high-pressure pipeline and squeal of an expansion valve can be avoided.

Description

Technical field [0001] The present invention relates to a liquid accumulator, in particular to a liquid accumulator for a refrigeration and heating system of an automobile air conditioner. Background technique [0002] Such a liquid reservoir is shown in Figure 5 of Japanese Patent Document 1 (Japanese Patent Publication No. 6-27232), and its bottom is provided with a supporting member supporting the lower part of the pipette. The supporting member is held around the bottom of the liquid reservoir, and, In order to prevent the pipette from falling, a predetermined gap d'is maintained between the bottom of the supporting member and the bottom of the liquid reservoir. In addition, a disc-shaped upper plate and a disc-shaped lower plate are arranged in the middle of the pipette, and the felt F is filled with desiccant between the upper and lower discs. In addition, a plurality of through holes as vent holes are formed on the upper and lower discs. [0003] In addition, as in Patent ...

Problems solved by technology

[0007] However, there is a shortcoming in the existing liquid reservoir, that is, when it is affected by loads such as automobile vibration or the high-pressure refrigerant on the high-pressure side of the automobile air-conditioning heating and cooling system has a sharp pressure change and causes an impact, it does not consider absorbing its vibration or Impact of high pressure refrigerant
