Title:
ONE-WAY VALVE, HEAT EXCHANGER, REFRIGERATION CYCLE SYSTEM, AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2023/040317
Kind Code:
A1
Abstract:
A one-way valve (300), a heat exchanger (100), a refrigeration cycle system, and an air conditioner, relating to the technical field of air conditioning. The one-way valve (300) comprises: a valve housing (320), provided with a valve outlet (322), a valve inlet (321), and a valve channel (323) forming the interior of the valve housing (320) and being in communication with the valve outlet (322) and the valve inlet (321); and a valve core (330) movably provided in the valve channel (323) in an axial direction, wherein L2/D is less than or equal to e2, e2 is a preset ratio, L2 is the length between two end points of a long edge of the valve core (330), and D is the equivalent diameter of an end face of one end of the valve core (330) corresponding to the valve outlet (322). According to the one-way valve (300), an upper limit value is set for a length-to-diameter ratio of the valve core (330) of the one-way valve, so as to reduce vibration collision of the valve core (330) and an inner wall of the valve housing (320), noise, etc. caused by an excessive length-to-diameter ratio. By means of the one-way valve (300), a good stability of the valve core (330) can be maintained during the flow of a refrigerant through the one-way valve (300).
