Problems solved by technology

[0005] (1) It is difficult for the filter screen holder with circular through holes to effectively separate the gas-liquid two-phase refrigerant, which makes the liquid separation capacity of the liquid separator low
Especially when the suction dryness of the compressor is small, it is difficult for the liquid separator to effectively separate the gas-liquid two-phase refrigerant
[0006] (2) It has a spherical perforated filter screen bracket with diversion function. Although it can improve the liquid separation capacity of the liquid separator, the gas-liquid two-phase refrigerant that has passed the diversion will cause impact on the wall of the liquid separator, mixing and disturbing, which is easy to Generates noise and suction pressure pulsations

Embodiment 1

[0053] This embodiment provides a liquid separator filter screen support, such as figure 2 and image 3 As shown, the liquid separator filter screen support of this embodiment includes a support main body 5 and a first through hole 53 . Wherein, the first through hole 53 is opened on the bracket main body 5; and, the first through hole 53 is provided with a flow guide structure 531 for guiding the flow of the liquid refrigerant. Wherein, the projection of the first through hole 53 on the reference plane extends along the circumferential direction of the bracket body 5; and, the projection of the first through hole 53 on the reference plane along the circumference of the bracket body 5 has a longer length The radial length of the main body 5 .

[0054] Wherein, the reference plane in this embodiment and the following embodiments is the plane where the plane part of the upper end surface of the bracket main body 5 is located (that is, as image 3 The upper end of the main bo...

Embodiment 2

[0057] Preferably, this embodiment provides a liquid separator filter screen support, compared with the previous embodiment, such as figure 2 and image 3 As shown, the first through hole 53 in this embodiment includes a first hole wall; wherein, the first hole wall is configured as a flow guiding structure 531 . Moreover, the upper end of the first hole wall extends to the upper end surface of the bracket body 5 , and the lower end of the first hole wall is a free end. In this embodiment, only part of the hole wall of the first through hole 53 needs to be provided as the flow guide structure 531 without additional installation of a flow guide, which not only reduces the cost, but also facilitates processing.

[0058] Preferably, the first hole wall (flow guiding structure 531 ) forms a concave arc surface. Here, by setting the diversion structure as a concave arc surface, the diversion effect on the liquid refrigerant is good, and the impact of the liquid refrigerant on th...

Embodiment 3

[0062] Preferably, this embodiment provides a liquid separator filter screen support, compared with the above embodiments, such as figure 2 and image 3 As shown, when the diversion structure 53 (the first hole wall) is arranged as a concave arc surface, the concave arc surface has the lowest point, and the lowest point is located at the lower end of the first hole wall (such as figure 2 lowest point of the dotted arc shown). The projection of the lowest point on the datum plane is the first point; the upper end of the first hole wall has the second point with the longest distance from the first point (such as figure 2 the highest point of the dotted arc shown). The angle α between the line connecting the second point and the lowest point and the reference plane ranges from 10° to 60°. Preferably, when the first hole wall forms a concave spherical surface, the distance between any point on the upper end of the first hole wall and the first point is equal, and the connect...

Abstract

The invention relates to a liquid distributor filter mesh bracket and a liquid distributor, and relates to the technical field of compressors. The mainly adopted technical scheme is that the liquid distributor filter mesh bracket comprises a bracket main body, wherein a first through hole is formed in the bracket main body; moreover, a flow guide structure is arranged in the first through hole and is used for guiding the flow of a liquid refrigerant, wherein the projection of the first through hole on a reference plane extends in the circumferential direction of the bracket main body; moreover, the length of the projection of the first through hole on the reference plane in the circumferential direction of the bracket main body is greater than the radial length of the bracket main body. The reference plane is the plane on which the plane part of the upper end surface of the bracket main body is positioned. The liquid distributor comprises the liquid distributor filter mesh bracket. A compressor comprises the liquid distributor. The liquid distributor filter mesh bracket is mainly used for improving the liquid distributing capacity of the liquid distributor, relieving the fluctuation of air suction pressure, reducing the noises of the liquid distributor and the compressor, and improving the performance of the compressor.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a liquid separator filter screen support and a liquid separator. Background technique [0002] A liquid separator (also known as a gas-liquid separator) is usually installed on the compressor, which is used between the evaporator and the pump body of the compressor to separate the gas-liquid mixed refrigerant from the evaporator, and the separated gaseous refrigerant enters the compressor. Compressed in the compressor cylinder, the separated liquid refrigerant is stored at the bottom of the liquid separator. Therefore, the main function of the liquid separator is to prevent the liquid refrigerant from directly entering the pump body of the compressor, thereby preventing the occurrence of a large amount of liquid hammer in the compressor. [0003] The filter holder in the dispenser plays a vital role in the liquid dispensing ability of the dispenser. The existing related liq...
