Further, the transition section 33 connects the inner wall of the accommodating groove 32 and the wall surface of the fixing plate 30.
In one embodiment, the receiving groove 32 is disposed along the inner wall of the connecting hole 31. That is, assuming that the receiving groove 32 is only a groove opened at any position on the inner wall of the connecting hole 31, if the receiving groove 32 is disposed along the circumferential direction of the inner wall of the connecting hole 31, the receiving groove 32 is formed as an annular groove, so that the solder ring can be directly placed in the annular receiving groove 32, and the placement of the solder ring increases the solder in comparison with the groove opened at any position on the inner wall of the connecting hole 31, thereby further enhancing the soldering strength between the fixing plate 30 and the first adapter 20.
In one embodiment, the receiving groove 32 formed as an annular groove may be provided in plurality, and the plurality of receiving grooves 32 arranged in an annular shape may be uniformly arranged along the axial direction of the connecting hole 31.

The guide groove is disposed at one end of the accommodation groove 32 close to the second and third ports 13 and 14; the arrangement is to lead the melted solder in the receiving groove 32 to the guiding groove under the action of gravity, so as to increase the penetration performance of the solder and the contact area between the solder and the first adapter 20, and further enhance the air tightness of the welding seam and the welding strength.
It should be noted that the end of the guiding groove far from the receiving groove 32 is spaced from the inner wall end surface of the connecting hole 31. That is, the guide groove is formed in an elongated shape on the inner wall of the connection hole 31, one end of the guide groove is connected to the accommodation groove 32, and the other end of the guide groove cannot penetrate the inner wall of the connection hole 31. Thus, the melted solder is prevented from flowing out of the guide groove to the outside of the connection hole 31 and along the first adapter tube 20, thereby causing flow soldering of the solder, resulting in solder failure.
As shown in fig. 3, an expanded flange 34 is punched at the position of the connection hole 31 on the fixing plate 30. The flange 34 is located at one end of the connecting hole 31 far away from the transition section 33, and the connecting hole 31 is located in the space surrounded by the flange 34. The expanded flanging 34 is formed at the position of the connecting hole 31 on the fixing plate 30 by punching, so that the contact area between the fixing plate 30 and the first connecting pipe 20 is increased, the welding firmness of the fixing plate and the first connecting pipe can be improved during welding, and the structural strength is improved.
Specifically, the receiving groove 32 is opened on the inner wall of the flange 34. That is, the receiving groove 32 can be opened at any position on the flange 34, and the solder or the solder ring can be placed, so that the fixing plate 30 and the first adapter 20 are soldered to each other by the solder. The distribution mode also has various distribution modes similar to those of the above-mentioned distribution modes on the inner wall of the connecting hole 31, and the details are not described herein.
Further, a plurality of filtering holes 35 are further formed in the fixing plate 30, and the plurality of filtering holes 35 are uniformly distributed along the circumferential direction of the fixing plate 30. When the gas-liquid mixed refrigerant falls onto the fixing plate 30 after being filtered by the filter screen 50, the filter holes 35 are used for passing the refrigerant, so that the liquid refrigerant flows into the bottom of the casing 10 through the filter holes 35.
The utility model also provides an air conditioning system (not shown), including reservoir 100.
The utility model provides a reservoir 100 through set up storage tank 32 at connecting hole 31 inner wall to make when welding first takeover 20 on fixed plate 30, can place the solder fixation in storage tank 32 in advance, avoid rocking and arousing droing of solder because of reservoir 100 in the brazing furnace, thereby lead to no welding wire between fixed plate 30 and the first takeover 20, and then influence the welding between fixed plate 30 and the first takeover 20.
