Installing structure of lower part cap in receiverdrier

Abstract

The present invention relates to a receiver-drier for separating liquid and gaseous refrigerant and removing moisture and impurities in the refrigerant, in which the lower cap is exactly assembled to the receiver-drier so as to air-tightly close a lower opening of the receiver-drier when the lower cap is screwed to the receiver-driver, thereby preventing a leakage and also facilely performing the assembling.The structure includes a receiver-drier tank having an opening at a lower end thereof; a body which is inserted into the opening to be screwed to the receiver-drier tank; a filter which is disposed at an upper side of the body to have a flange portion for assisting in exactly assembling the body and filter; and a sealing member which is provided at a junction portion between the body and the filter so as to air-tightly close the receiver-drier tank.

Description

TECHNICAL FIELD [0001]The present invention relates to a receiver-drier for separating liquid and gaseous refrigerant and removing moisture and impurities in the refrigerant, and more particularly, to a receiver-drier for separating liquid and gaseous refrigerant and removing moisture and impurities in the refrigerant, in which the lower cap is exactly assembled to the receiver-drier so as to air-tightly close a lower opening of the receiver-drier when the lower cap is screwed to the receiver-driver, thereby preventing a leakage and also facilely performing the assembling.BACKGROUND ART [0002]In general, as shown in FIG. 1, a receiver-drier is attached to one side of a header tank of a condenser 10, and constructed such that a moisture absorbent 24 for removing a gaseous working fluid is provided in the tank of which an upper side is closed and a lower side is opened and the lower side of the tank is closed using a lower cap 30 having a filter for removing impurities contained in th...

AI Technical Summary

Benefits of technology

[0006]It is an object of the present invention to provide a receiver-drier for separating liquid and gaseous refrigerant and removing moisture and impurities in the refrigerant, in which a stopping portion is formed at an inner circumferential surface of a receiver-drier tank so as to prevent a filter of a two-piece type lower cap from being separated after an assembling process.

[0007]It is another object of the present invention to provide a receiver-drier for separating liquid and gaseous refrigerant and removing moisture and impurities in the refrigerant, in which the filter and body are coupled to have multiple sides and vertexes, thereby preventing relative rotation between components, which is generated by excessive rotational force upon an assembling process.

[0008]It is yet another object of the present invention to provide a receiver-drier for separating liquid and gaseous refrigerant and removing moisture and impurities in the refrigerant, in which an inclined portion and a guide surface are formed in the inner circumferential surface of the receiver-drier tank so that the two-piece type lower cap can be exactly assembled to the opening of the receiver-drier, and the filter of the lower cap is formed with a flange portion protruded to an outside so that the two-piece type lower cap can be exactly assembled along the inclined portion and the guide surface.

[0010]In order to achieve the object, there is provided a receiver-drier for separating liquid and gaseous refrigerant and removing moisture and impurities in the refrigerant includes a receiver-drier tank having an opening at a lower end thereof; a body which is inserted into the opening to be screwed to the receiver-drier tank; a filter which is disposed at an upper side of the body to have a flange portion for assisting in exactly assembling the body and filter; and a sealing member which is provided at a junction portion between the body and the filter so as to air-tightly close the receiver-drier tank.

Problems solved by technology

However, in the one piece-type lower cap, if one of the filter and body is damaged or out of order, the function of the whole part is lost and thus the whole lower cap has to be replaced.

Therefore, it is impossible to perform its function.

Further, since the filter has a smaller diameter than a diameter of a screw thread formed on the body of the lower cap, when the lower cap is assembled to the receiver-drier, the filter which is positioned at an upper side of the body becomes inclined and thus assembled erroneously.
