Distributor, heat exchanger device and air conditioner

Abstract

The invention provides a liquid distributor, a heat exchanger device and an air conditioner. According to the distributor, a uniform flow part is arranged in a liquid storage cavity and is provided with a sharp part, and the sharp part is arranged towards a main inlet pipe. The top point of the sharp part and the center line of the main inlet pipe are aligned. Refrigerant fluid flowing out of themain inlet pipe impacts on the sharp part and then is evenly scattered in the liquid storage cavity in various directions, accordingly, the refrigerant fluid stored at the bottom of the liquid storagecavity is in a uniform mixing state and is conveyed into a heat exchanger through a branch flow dividing pipe, accordingly, it is guaranteed that the proportion of a gas-phase refrigerant and a liquid-phase refrigerant in various refrigerant branches in the heat exchanger is consistent, and the heat exchange capability of the heat exchanger is better improved. The distributor is arranged on the heat exchanger device, and high heat exchange capability is achieved. The air conditioner is provided with the heat exchanger device, and a high energy efficiency coefficient is achieved.

Description

technical field [0001] The invention belongs to the technical field of air conditioning and refrigeration, and in particular relates to a distributor, a heat exchanger device and an air conditioner. Background technique [0002] The heat exchanger of the air conditioner is used to exchange heat between the refrigerant and the air in the room or the atmosphere. In order to improve the heat exchange efficiency, there are multiple refrigerant branches in the heat exchanger. In order to distribute the refrigerant to each refrigerant branch, the air conditioner A distributor is generally provided at the inlet of the heat exchanger of the heat exchanger. In order to make full use of the heat exchange area of ​​the heat exchanger and improve the heat exchange capacity of the heat exchanger, the distributor needs to evenly distribute the refrigerant to each refrigerant branch inside the heat exchanger, so that the state of the refrigerant in each refrigerant branch is consistent. ...

AI Technical Summary

Problems solved by technology

[0003] The air conditioner further includes a throttling device. The high-pressure liquid refrigerant becomes a low-pressure gas-liquid mixed refrigerant after being throttled by the throttling device. The gas-liquid mixed refrigerant enters the heat exchanger through the distributor, and the refrigerant pipeline of the air conditioner inevitably There is a detour, and the refrigerant will generate centrifugal force when it flows through the detour. The centrifugal force will cause the gas-liquid mixed refrigerant to fail to achieve a uniform mixing state in the distributor, resulting in inconsistent refrigerant states in each refrigerant branch in the heat exchanger, that is, each refrigerant branch The proportion of gas-phase refrigerant and liquid-phase refrigerant in the medium is inconsistent, and the liquid-phase refrigerant in the refrigerant branch circuit with more liquid-phase refrigerant cannot be completely evaporated, resulting in waste of cooling capacity; the heat exchange in the refrigerant branch circuit with more gas-phase refrigerant is insufficient, which increases the compressor capacity. load

[0004] In the prior art, those skilled in the art ensured that the proportions of gas-phase refrigerant and liquid-phase refrigerant in each refrigerant branch in the heat exchanger were consistent by strictly controlling the verticality of the distributor, but the applicant found that even if the distributor was installed Even if the vertical requirements are met, the gas-phase refrigerant and liquid-phase refrigerant in the distributor cannot be guaranteed to mix evenly, thus reducing the heat transfer capacity of the heat exchanger and the energy efficiency coefficient of the air conditioner
