Refrigeration fluid uniform distributor

Abstract

The invention discloses a refrigeration fluid uniform distributor applied to the technical field of refrigeration system equipment. The refrigeration fluid uniform distributor comprises a fluid distributor and a fluid supply pipe. A distribution cavity is formed in the fluid distributor. The front side of the distribution cavity of the fluid distributor is provided with a fluid inlet hole. The rear side of the distribution cavity is provided with a plurality of fluid distribution pipe holes. A throttling hole is arranged between the distribution cavity and the fluid inlet hole. The fluid supply pipe is in butt joint with the fluid inlet hole. The fluid supply pipe is provided with a spiral fluid supply pipe hole. When the refrigeration fluid uniform distributor is in service, refrigeration fluid passes an expansion valve and then goes into the spiral fluid supply pipe hole of the fluid supply pipe in front of the fluid distributor to drive fluid to rotate; light bubbles can gather in the center of the pipe, goes into the throttling hole of the fluid distributor and is compressed and then expanded. The bubbles are smashed and diminished and uniformly flow onto all the downstream fluid distribution pipe holes along with the fluid. Thus, the purpose of improving the nonuniformity of an original fluid distributor is achieved.

Description

technical field [0001] The invention is used in the technical field of refrigeration system equipment, and in particular relates to a refrigerant uniform liquid separator. Background technique [0002] In the refrigeration system, after the refrigerant passes through the throttling device, the pressure decreases and flows into the evaporator. Whether the refrigerant can be evenly distributed to each branch of the evaporator has a crucial impact on the performance of the evaporator and even the entire refrigeration system. The liquid separator is an important auxiliary device, which is installed in front of the evaporator to evenly distribute the refrigerant to each branch of the evaporator. Practical application There is uneven distribution in the existing liquid separator. If the distribution is uneven, some branch refrigerants will be too much, and the evaporator will be frosted. Less, the heat transfer area of ​​the evaporator cannot be fully utilized. The overall perfo...

Problems solved by technology

[0004] The reason for the unevenness of the liquid separator: the liquid separator is installed after the expansion valve, and the refrigerant liquid does not reach the liquid separator until it is throttled and depressurized, so the liquid along the way inevitably absorbs heat from the pipe wall and generates flash steam , mixed in the liquid in the form of air bubbles, when the air bubbles enter the dispensing tube downstream of the dispenser without control, there are more bubbles in the liquid of some dispensing pipes, which will cause the flow rate to be too small, resulting in uneven flow distribution of the dispenser
