Description

Technical Field

[0001] The utility model belongs to the technical field of condensers and relates to a condenser drying bottle. Background Technique

[0002] An automotive condenser is an important part of an automotive air conditioning system. The quality of its products directly affects the air conditioning refrigeration system. Automotive condensers are usually equipped with drying bottles, which are installed on the condensers. The main functions are to filter impurity particles and absorb moisture, and the drying bottle needs to ensure good sealing performance.

[0003] Condenser drying bottles usually adopt a structure with both ends blocked. For example, Figure 1 and 2 show an existing automotive condenser drying bottle, which mainly consists of a bottle body 1, a plug cap 2, a bottle body joint 3, and a plug 4. The plug cap 2 and the plug 4 are respectively located at both ends of the bottle body 1 to block it. A bottle body joint 3 is provided at the end of the bottle body 1 and connected to the plug 4. When the drying bottle is produced, it is necessary to apply solder paste at the joints between both ends of the bottle body and the bottle body joint 3 and the plug 4, then knock in the bottle body joint 3 and the plug 4, and then weld them into one body through a brazing furnace, and then install the plug 4 onto the bottle body joint 3. This structure makes the operation during production relatively cumbersome, time-consuming and laborious, resulting in low production efficiency, and it is easy to cause deformation of the housing 1 or misalignment during the installation of the bottle body joint 3, affecting the product quality.

[0004] Therefore, it is necessary to design a condenser drying bottle with a simple structure and good sealing performance to simplify the processing technology and improve the production efficiency. Content of the Utility Model

[0005] The purpose of the utility model is to address the above problems in the existing technology and propose a condenser drying bottle. The technical problem to be solved by this device is to design a condenser drying bottle with a simple structure, good sealing performance and easy production.

[0006] The purpose of the utility model can be achieved by the following technical solutions:

[0007] A condenser drying bottle includes a bottle body, a plug cap and a plug. The plug cap and the plug are respectively installed at both ends of the bottle body. The plug cap is brazed with the bottle body as a whole. The plug is connected to the bottle body through threads. Several sealing rings are installed on the plug to ensure the sealing performance at the connection between the plug and the bottle body. A connection groove matching with the plug cap is provided at one end of the bottle body, and the plug cap is installed in the connection groove.

[0008] Compared with the existing condenser drying bottle, for the condenser drying bottle provided in this embodiment, the plug is directly installed on the bottle body, eliminating the structure of the bottle body joint. There is no need to knock the bottle body joint into the end of the bottle body, and there is no situation of improper assembly. While saving materials, the processing procedures are reduced and the processing efficiency is improved. A connection groove matching with the plug cap is provided at the end of the bottle body, facilitating the installation and positioning of the plug cap without deviation. Multiple sealing rings are arranged at the connection of the plug for sealing, further improving the sealing performance.

[0009] The plug is made of plastic material, with external threads provided on the plug, and a retaining ring is provided at the end of the plug.

[0010] With the above structure, after the plug is installed, the outer wall of the retaining ring abuts against the inside of the bottle body for sealing.

[0011] One end of the bottle body connected to the plug is provided with a reduced diameter matching with the plug. There is an internal thread inside the reduced diameter matching with the external thread on the plug, and a transition groove is provided inside the bottle body, and the transition groove is located inside the reduced diameter.

[0012] Furthermore, two sealing rings are installed on the plug. The middle of the plug is provided with a first clamping groove and a second clamping groove, and the two sealing rings are respectively installed in the first clamping groove and the second clamping groove.

[0013] With the above structure, after the plug is installed, the two sealing rings are located in the transition groove inside the reduced diameter, and the double-sealing gasket structure can effectively ensure the sealing performance.

[0014] Compared with the prior art, this condenser drying bottle has the following advantages:

[0015] 1. In this condenser drying bottle, the end of the bottle body where the plug is installed adopts an integrated design, and the plug is directly installed on the bottle body, with a simple structure and easy processing. Compared with the structure of the existing drying bottle, the structure of the bottle body joint is eliminated. There is no need to apply solder paste and then knock the bottle body joint into the bottle body for brazing fixation, reducing the time for applying solder paste and installing the bottle body joint, and also avoiding the risk of leakage caused by improper joint assembly, reducing rework. While saving materials, the processing procedures are reduced and the processing efficiency is improved.

[0016] 2. A connection groove matching with the plug cap is provided at the end of the bottle body, facilitating the installation and positioning of the plug cap. The plug cap fits more closely with the bottle body and will not deviate during assembly, causing leakage. At the same time, multiple sealing rings are arranged at the connection of the plug for sealing, further improving the sealing performance. BRIEF DESCRIPTION OF THE DRAWINGS
