[0003] According to the public announcement of an evaporator for an automotive air conditioner (Announcement No.: CN202126118U), the above application uses an integrated structure design for the evaporator baffle and throttling plate, which can effectively reduce standard assembly time, reduce the phenomenon of baffle and throttling plate falling off during assembly, and improve the welding quality of the core. The evaporator manifold is connected by riveting and welding with double-sided flanged plates with welding layer, which effectively improves the first inspection pass rate of welded parts.
[0004] However, during actual use, the feed inlet of the above-mentioned equipment is subjected to pressure impacts during long-term use, which causes the connection between the connecting pipe and the equipment to loosen, resulting in easy leakage of liquid; in view of this, we propose an automotive air conditioning evaporator. Summary of the Invention
[0005] The purpose of this invention is to provide an automotive air conditioning evaporator to solve the problems mentioned in the background section.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an automotive air conditioning evaporator, comprising an evaporator body, a collector fixedly connected to the side of the evaporator body, and a sealing assembly provided on the side of the collector, the sealing assembly comprising:
[0007] The mounting component is fixedly connected to the side of the collector, and a connecting pipe is fixedly connected to the inner wall side of the mounting component. The outer surface of the connecting pipe is threaded with the mounting pipe.
[0008] A spring is fixedly connected to the inner wall side of the mounting component, and a sealing element is fixedly connected to the end of the spring. A sealing ring is fixedly connected to the inner wall of the sealing element.
[0009] Preferably, the sealing element is fitted onto the outer surface of the connecting pipe, and the size of the sealing element is adapted to the size of the mounting pipe, so that the sealing element can be fitted onto the outer surface of the mounting pipe well.
[0010] Preferably, the number of springs is four, and the four springs are respectively arranged on the side of the sealing element near the top corner. The connecting pipe is connected to the inside of the manifold, so that the liquid inside the evaporator body can flow out through the connecting pipe after passing through the manifold.
[0011] Preferably, the inner wall of the sealing ring is provided with an arc-shaped groove, and the size of the sealing ring is adapted to the size of the mounting tube. This allows the sealing ring to fit well onto the outer surface of the mounting tube, thereby improving the sealing performance between the mounting tube and the connecting tube.
[0012] Preferably, the mounting component is provided with a limiting assembly on its side. The limiting assembly includes a cover plate, which is disposed on the side of the mounting component. A storage groove is formed on the inner wall of the cover plate. A rotating component is rotatably connected to the bottom of the inner wall of the storage groove. A pressing component is threadedly connected to the outer surface of the rotating component. A convex ring is fixedly connected to the outer surface of the mounting tube.
[0013] Preferably, the position of the pressing member corresponds to the position of the convex ring, and the bottom of the pressing member is provided with an arc-shaped groove.
[0014] Preferably, the end of the rotating component is positioned to penetrate the top of the inner wall of the storage groove, and the size of the cover plate is adapted to the size of the mounting component.
[0015] Compared with the prior art, the present invention provides an automotive air conditioning evaporator, which has the following beneficial effects:
[0016] 1. To prevent leakage at the connection point during long-term use of the automotive air conditioning evaporator, the mounting pipe and connecting pipe are aligned before being threaded together. The end of the mounting pipe contacts the inner wall of the mounting component, and the spring force pushes the seal towards the mounting pipe. After the mounting pipe and connecting pipe are fully aligned, the seal is completely fitted onto the outer surface of the mounting pipe, thus improving the sealing performance between the mounting pipe and the connecting pipe.
[0017] 2. In order to make the connection between the installation pipe and the equipment tighter, after the installation pipe and the connecting pipe are connected, the cover plate sleeved on the outer surface of the installation pipe is connected to the installation component. Then, by rotating the rotating component, the pressing component moves downward inside the storage groove, so that the pressing component limits the installation pipe. At the same time, the convex ring is also limited by the pressing component, so that the installation pipe will not loosen when the connecting pipe is subjected to pressure, and at the same time, the sealing performance of the installation component is better.

[0024] In this embodiment of the present invention, the mounting component 301 is fixedly connected to the side of the collector 2, and a connecting pipe 302 is fixedly connected to the inner wall side of the mounting component 301. The connecting pipe 302 communicates with the inside of the collector 2, so that the liquid inside the evaporator body 1 can flow out through the connecting pipe 302 after passing through the collector 2. The outer surface of the connecting pipe 302 is threaded with a mounting pipe 306. Four springs 303 are fixedly connected to the inner wall side of the mounting component 301, and the four springs 303 are respectively arranged on the side of the sealing component 304 near the top corner. The ends of the springs 303 are fixed. A sealing element 304 is fixedly connected to the connecting pipe 302. The sealing element 304 is fitted onto the outer surface of the connecting pipe 302. The size of the sealing element 304 is adapted to the size of the mounting pipe 306, which allows the sealing element 304 to fit well onto the outer surface of the mounting pipe 306. A sealing ring 305 is fixedly connected to the inner wall of the sealing element 304. The inner wall of the sealing ring 305 is provided with an arc-shaped groove. The size of the sealing ring 305 is adapted to the size of the mounting pipe 306, which allows the sealing ring 305 to fit well onto the outer surface of the mounting pipe 306, thereby improving the sealing performance between the mounting pipe 306 and the connecting pipe 302.
[0025] Meanwhile, a limiting component 4 is provided on the side of the mounting component 301. The limiting component 4 includes a cover plate 401, which is located on the side of the mounting component 301. The size of the cover plate 401 is adapted to the size of the mounting component 301. A storage groove 402 is formed on the inner wall of the cover plate 401. A rotating component 404 is rotatably connected to the bottom of the inner wall of the storage groove 402. The end of the rotating component 404 is set through the top of the inner wall of the storage groove 402. A pressing component 403 is threadedly connected to the outer surface of the rotating component 404. The position of the pressing component 403 corresponds to the position of the convex ring 405. A bottom of the pressing component 403 is provided with... The arc-shaped groove has a protruding ring 405 fixedly connected to the outer surface of the mounting tube 306. After the mounting tube 306 is connected to the connecting tube 302, the cover plate 401 fitted on the outer surface of the mounting tube 306 is connected to the mounting component 301. Then, by rotating the rotating component 404, the pressing component 403 moves downward inside the storage groove 402, so that the pressing component 403 limits the mounting tube 306. At the same time, the protruding ring 405 is also limited by the pressing component 403, so that the mounting tube 306 will not loosen when the connecting tube 302 is subjected to pressure, and the sealing performance of the mounting component 301 is better.
[0026] In this invention, during use, the mounting tube 306 and the connecting tube 302 are aligned and then threaded together. The end of the mounting tube 306 contacts the inner wall of the mounting member 301, and the elastic force of the spring 303 pushes the sealing member 304 to move towards the mounting tube 306. After the mounting tube 306 and the connecting tube 302 are fully aligned, the sealing member 304 is fully fitted onto the outer surface of the mounting tube 306, which allows the sealing ring 305 to fit onto the outer surface of the mounting tube 306, thereby improving the sealing performance between the mounting tube 306 and the connecting tube 302.
[0027] Furthermore, after the mounting tube 306 is connected to the connecting tube 302, the cover plate 401 sleeved on the outer surface of the mounting tube 306 is connected to the mounting component 301. Then, by rotating the rotating component 404, the pressing component 403 moves downward inside the storage groove 402, so that the pressing component 403 limits the mounting tube 306. At the same time, the protruding ring 405 is also limited by the pressing component 403, so that the mounting tube 306 will not loosen when the connecting tube 302 is subjected to pressure, and at the same time, the sealing performance of the mounting component 301 is better.
