Detailed ways

The preferred embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings; it should be understood that the preferred embodiments are only for illustrating the present utility model, rather than limiting the protection scope of the present utility model.

As shown in Figures 1 and 2, the utility model provides a condenser joint for connecting to the collector, including a body 1 and a mounting part provided on the body 1 for brazing connection with the collector 2. The mounting hole 3 used to communicate with the collecting pipe, the body 1 is also provided with a guide tube 5 communicating with the mounting hole 2, the guide tube 5 is interference fit with the mounting hole 2; A relief notch is provided on the body 1 along the axial direction of the installation hole 3 and below the guide tube 5 .

Specifically, a guide pipe 5 is extruded through the installation hole 3 on the condenser joint body 1, and the guide pipe 5 is in interference fit with the installation hole 2; when the condenser joint enters the brazing furnace for brazing , under the guidance and positioning of the guide pipe 5, the side hole (not shown in the drawings) of the collector pipe (not shown in the drawings) can quickly and accurately align with the installation hole 3 of the condenser joint. The side hole of the collecting pipe is sleeved on the guide pipe 5 and is in contact with the installation part 2, and the whole connection work is completed by brazing the contact part between the guide pipe 5 and the installation part 2 through the brazing furnace, because the side hole of the collecting pipe is brazed The welding part is outside the installation hole 2 and is blocked by the guide tube 5, therefore, during the brazing process, the brazing flux will not flow into the installation hole 3 of the joint body 1, and the guide tube 4 also has a supporting effect on the header , in order to facilitate the welding work on the header and improve the strength of the brazing part. The utility model overcomes the deficiencies of the prior art, prevents flux from flowing back into the installation hole of the condenser joint, thereby improving the problems of smaller size of the installation hole of the condenser joint, presence of flux, and unsatisfactory roughness.

In addition, along the axial direction of the installation hole 3 and located below the guide tube 5, a relief notch is provided on the body 1, and the body 1 also includes a threaded hole 4, and the threaded hole 4 is connected with the relief. The gap is connected; the cross-section of the relief gap along the axial direction of the threaded hole 4 is a square structure, that is, the cross-section of the body 1 along the axial direction of the mounting hole 3 is a "7"-shaped structure or an "L" shape Structure; the utility model adopts the design of the gap, which can not only prevent the fixing screw from being hit on the collecting pipe, but also cause damage to the brazing part of the collecting pipe and the condenser structure mounting hole due to the excessive length of the screw or the excessive tightening force. Destruction will affect its sealing effect. At the same time, it can also reduce the weight of the condenser joint and the brazing area of the installation part, thereby improving the brazing quality and making it easy to observe whether the brazing is successful.

As an improvement of this embodiment, the length of the guide tube 5 inserted into the collector is less than or equal to 1/2 of the diameter of the collector and greater than or equal to 1/6 of the diameter of the collector , to enhance the role of the guide tube 5 in positioning, guiding and supporting the header.

As an improvement of this embodiment, the guide tube 5 on the side close to the installation hole 3 is provided with a guide taper. It is slightly smaller than the inner diameter near the installation hole 3, which is beneficial for the guide tube to be extruded and inserted into the installation hole 3; in this embodiment, the guide taper is set to 1°.

The above descriptions are only preferred embodiments of the utility model, and are not intended to limit the utility model. Obviously, those skilled in the art can make various changes and modifications to the utility model without departing from the spirit and scope of the utility model. In this way, if these modifications and variations of the utility model fall within the scope of the claims of the utility model and equivalent technologies thereof, the utility model is also intended to include these modifications and variations.
