Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The filter is communicated with the air-conditioning heat exchanger and is of a tubular structure with two thin ends and a thick middle part. The filter is internally provided with a filter screen for filtering impurities in the refrigerant. As shown in fig. 1, the conventional filter 10 requires spinning one end of a pipe to be reduced, then pressing a filter screen in the middle of the pipe, and then spinning the other end of the filter to be reduced. The prior art filters are cumbersome to operate.
As shown in fig. 2 to 4, the present application provides a filter for an air conditioner heat exchanger, which includes a first pipe body 100, a second pipe body 200, and a screen structure. The first pipe 100 includes a first large opening end and a first small opening end. The second tube 200 includes a second large opening end and a second small opening end, the second large opening end is connected to the first large opening end, and the first tube 100 and the second tube 200 together define a cavity. The filter screen structure sets up in holding the intracavity, and the filter screen structure includes ring carrier 310 and the filter screen 320 that covers ring carrier 310 inner space, and ring carrier 310 includes the periphery wall, and the seam crossing of first body 100 of periphery wall butt and second body 200. Wherein, the first big mouth end and the second big mouth end are both arranged with the periphery wall in a pressing fit manner.
The application provides a filter of an air conditioner heat exchanger, which is connected in the air conditioner heat exchanger (an evaporator or a condenser) and used for filtering a refrigerant of an air conditioner so as to block impurities. Specifically, the thick body divides into two parts in the middle of will originally the thin two ends of the filter in this application for the spinning reduction operation to the thin body of two ends can go on simultaneously, then carries out filter screen 320's fixed again. Compared with the structure in the prior art, the filter in the application can be manufactured and molded only in two processes (the first step is to spin two pipes (namely the first pipe 100 and the second pipe 200) simultaneously to reduce the caliber, and the second step is to install the filter screen 320), so that the processing efficiency is higher, and the time is saved.
In the embodiment, two annular press grooves are formed in the outer peripheral wall, the first large opening end and the second large opening end are arranged at intervals, and the first large opening end and the second large opening end are pressed into the two press grooves in a one-to-one correspondence mode. Namely, the two end parts are not in direct contact with each other, so that the two end parts do not generate position interference when being pressed and deformed.
In another embodiment, the outer peripheral wall is provided with an annular pressure groove, the first large opening end and the second large opening end are stacked, and the first large opening end and the second large opening end are pressed into the pressure groove. Specifically, the diameter of the first large mouth end is greater than the diameter of the second large mouth end. The first big mouth end, the second big mouth end and the annular bracket 310 are pressed together at the same time, so that the sealing performance is ensured.
In another embodiment, the outer peripheral wall is provided with an annular indent, the first large opening end is aligned and abutted with the second large opening end, and the outer end parts of the first large opening end and the second large opening end are pressed into the indent.
In one embodiment, the outer edge of the filter mesh 320 abuts the outer peripheral wall. That is, the outer edge of the filter screen 320 is disposed between the outer peripheral wall and the first large-mouth end or the second large-mouth end. Preferably, the filter screen 320 can be provided with a structure of an aluminum filter screen, and the filter screen is extruded and deformed by pressing, so that the mesh of the filter screen can be sealed, on one hand, the air tightness is ensured, and on the other hand, the connection process between the filter screen 320 and the ring can be omitted, that is, the filter screen 320 and the ring bracket 310 can be connected simultaneously in the process of pressing the first pipe 100, the second pipe 200 and the ring bracket 310.
According to some embodiments, two filter screens 320 are included, and the two filter screens 320 are spaced apart and both cover the inner space of the annular bracket 310.
According to some embodiments, the outer edges of the two filter screens 320 are abutted against the outer peripheral wall, and one filter screen 320 is disposed between the first large opening end and the outer peripheral wall, and the other filter screen 320 is disposed between the second large opening end and the outer peripheral wall.
