Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0014] Such as figure 1 As shown, a refrigerant flow distributor for an air conditioner includes a base 2 and a nozzle 3 installed in the base, the nozzle 3 is sleeve-shaped and one end is a horn hole 5, and one end of the base 2 is provided with a stepped hole, The inner diameter of the large diameter part of the stepped hole matches the outer diameter of the nozzle 3 and the length is greater than the length of the nozzle 3. The nozzle is placed in the base and the large end surface of the horn hole 5 is in contact with the stepped surface, and the diameter of the small port of the horn hole 5 is 4mm~ 6mm, the diameter of the large port of the horn hole 5 is the same as the diameter of the small diameter part of the step hole of the base body 2, and the other end of the base body 2 is provided with a number of distribution holes 6 for instal...

Abstract

The invention relates to a refrigerant flow distributor of an air conditioner, which comprises a substrate of the refrigerant flow distributor. The refrigerant flow distributor is characterized in that: a step hole at one end of the substrate is provided with a nozzle; the nozzle is in a sleeve shape, and one end of the nozzle is designed into a bellmouth orifice shape; the larger end face of the bellmouth orifice butts against a step surface of the substrate; the bellmouth orifice of the nozzle and the other end of the substrate are used for communicating with a shunting hole provided with capillaries; and an included angle between an axis of the shunting hole and an axis of the substrate is between 10 and 20 DEG to form a cone-shaped diversion trench. When refrigerant flows from the nozzle end into the substrate through an input pipe, a vortex is formed at the bellmouth of the nozzle so as to make the refrigerant uniformly flow out from each capillary. The refrigerant flow distributor is easy to assemble, can ensure the refrigerant to uniformly enter the distributor, makes an air conditioning system work under the optimized ideal condition, and makes the system more safely and reliably operate.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a refrigerant flow uniform distributor of the air conditioner. Background technique [0002] The air conditioner is mainly composed of indoor and outdoor heat exchangers, compressors, controllers and system pipelines. Due to the large number of pipelines connecting the indoor and outdoor units of the existing air conditioners above 2P, in order to reduce the flow and pressure loss, the refrigerant needs to be Divided into multiple branches, this will lead to different refrigerant flows in each branch. In order to solve the problem of refrigerant flow distribution, a distributor is generally installed in the pipeline, and then the distribution is made evenly by adjusting the length of the capillary or the number of U-shaped tubes. , so as to ensure that the system can run better. [0003] The traditional distributor has no nozzle, and there is no conical guide groove in ...
