Description

Technical Field

[0001] The present application relates to the technical field of evaporators, and in particular to a sealing structure of an evaporator shell. Background Art

[0002] The evaporator is a very important part of the four major parts of refrigeration. The low-temperature condensed liquid passes through the evaporator to exchange heat with the outside air, vaporize and absorb heat to achieve the cooling effect. The evaporator is mainly composed of two parts: the heating chamber and the evaporation chamber. The heating chamber provides the heat required for evaporation to the liquid, causing the liquid to boil and vaporize, and the evaporation chamber completely separates the gas and liquid phases. As the core component of the refrigeration system, the design and installation of the sealing structure of the evaporator is very important;

[0003] With respect to the above-mentioned related technologies, the inventor believes that the sealing of the evaporator shell is usually carried out by a traditional gasket sealing or welding sealing method. The gasket sealing method may have poor sealing performance and leakage problems due to improper operation during installation. Although the welding sealing method has a better sealing effect, the installation process is complicated, and thermal stress may be generated during the welding process, resulting in shell deformation or material performance degradation. Therefore, the existing technical solutions still need to be improved in terms of sealing effect and installation efficiency.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0005] In order to solve the problem that the sealing of the evaporator shell currently usually adopts the traditional gasket sealing or welding sealing method, the gasket sealing method may lead to poor sealing performance and leakage due to improper operation during installation, and although the welding sealing method has a better sealing effect, the installation process is complicated, and thermal stress may be generated during the welding process, resulting in shell deformation or material performance degradation. The present application provides an evaporator shell sealing structure.

[0006] The present application provides an evaporator shell sealing structure adopting the following technical solution:

[0007] An evaporator shell sealing structure includes a shell, two fixing rods are fixedly connected to the left and right outer walls of the shell, the other ends of the multiple fixing rods are commonly fixedly connected to a cross plate, the ends of the two cross plates close to the shell are fixedly connected to sleeves, first limit rods are arranged in the two sleeves, and a connecting mechanism for the evaporator shell is arranged on the shell.

[0008] Preferably, the connecting mechanism comprises a top cover arranged at the upper end of the shell, a pull ring is fixedly connected to the upper end of the top cover, and limiting holes are arranged on the left and right outer walls of the top cover.

[0009] Preferably, the two first limit rods are elastically connected to the corresponding cross plate through a spring, and one end of the two first limit rods away from the shell is fixedly connected to a pull rod, and the other ends of the two pull rods extend to one side of the corresponding cross plate.

[0010] Preferably, a plurality of the fixing rods and a plurality of the first limiting rods are provided with limiting openings, and a second limiting rod is disposed transversely in the plurality of limiting openings.

[0011] Preferably, a rubber sealing pad is disposed around the inner wall of the shell, and the rubber sealing pad is fixedly connected to the inner wall of the shell, and through openings are disposed on both the left and right sides of the shell.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] 1. Place the top cover directly into the shell, and align the two guide rods with the corresponding guide grooves. When the guide block is fully inserted into the guide groove, the alignment is complete. Pull out the second limit rod. After the limit function is gone, the first limit rod will move down under the elastic action of the spring, pass through the through opening, and enter the through opening of the shell to complete the limit, improve the installation efficiency, and complete the connection between the shell and the top cover. The setting of the rubber sealing pad can increase the sealing performance when the shell and the top cover are connected;

[0014] 2. When the shell and the top cover need to be disassembled later, you only need to pull the two pull rods by hand. When the pull rods move, they will drive the first limit rods to move, so that the two first limit rods leave the corresponding through openings, and insert the second limit rod again according to the diagram. At this time, the shell and the top cover can be easily disassembled, and the overall disassembly and installation are extremely convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following is combined with Figure 1-3This application is described in further detail.

[0020] The present application embodiment discloses an evaporator housing sealing structure. Figure 1-3 An evaporator shell sealing structure includes a shell 1, two fixing rods 6 are fixedly connected to the outer walls on the left and right sides of the shell 1, the other ends of the multiple fixing rods 6 are commonly fixedly connected to a cross plate 3, the two cross plates 3 are fixedly connected to one end of the shell 1, the first limiting rods 11 are arranged in the two sleeves 5, and a connecting mechanism for the evaporator shell is arranged on the shell 1.

[0021] Reference Figure 1-3 The connecting mechanism includes a top cover 2 arranged at the upper end of the shell 1, a pull ring 8 is fixedly connected to the upper end of the top cover 2, and limiting holes 10 are arranged on the left and right outer walls of the top cover 2. Two first limiting rods 11 are elastically connected to the corresponding cross plate 3 through springs 12. The ends of the two first limiting rods 11 away from the shell 1 are fixedly connected to the pull rod 4, and the other ends of the two pull rods 4 extend to one side of the corresponding cross plate 3. Limiting openings 14 are arranged in multiple fixed rods 6 and multiple first limiting rods 11, and second limiting rods 7 are commonly arranged across the multiple limiting openings 14.

[0022] Align the two guide rods with the corresponding guide grooves. When the guide block is fully inserted into the guide groove, the action is completely aligned. At this time, pull out the second limit rod 7. After the limiting effect is gone, the first limit rod 11 will move downward under the elastic action of the spring 12, and pass through the through opening 13 and enter the through opening 13 of the shell 1, completing the limiting, improving the installation efficiency, and completing the connection between the shell 1 and the top cover 2. By setting the rubber sealing pad 9, the sealing performance of the connection between the shell 1 and the top cover 2 can be increased.

[0023] Reference Figure 2 A rubber sealing pad 9 is arranged around the inner wall of the shell 1, and the rubber sealing pad 9 is fixedly connected to the inner wall of the shell 1. The rubber sealing pad 9 can increase the airtightness of the shell 1. Through openings 13 are arranged on the left and right sides of the shell 1. Two guide rods are symmetrically arranged at the lower end of the top cover 2, and two guide grooves matching the guide rods are symmetrically arranged on the inner wall of the shell 1.

[0024] The implementation principle of the sealing structure of the evaporator shell of the embodiment of the present application is as follows: when in use, the top cover 2 is directly placed into the interior of the shell 1, and the two guide rods are aligned with the corresponding guide grooves. When the guide block is fully inserted into the guide groove, the alignment is just complete. At this time, the second limiting rod 7 is pulled out. After the limiting effect is gone, the first limiting rod 11 is moved downward by the elastic action of the spring 12, and passes through the through-hole 13 and enters the through-hole 13 of the shell 1, completing the limiting and completing the connection between the shell 1 and the top cover 2. By setting the rubber sealing pad 9, the sealing performance when the shell 1 and the top cover 2 are connected can be increased;

[0025] When the housing 1 and the top cover 2 need to be disassembled later, it is only necessary to pull the two pull rods 4 by hand. When the pull rods 4 move, the first limit rods 11 will move, so that the two first limit rods 11 leave the corresponding openings 13, and the second limit rod 7 will be pressed again. Figure 1 Just insert it, and then the shell 1 and the top cover 2 can be easily disassembled, and the overall disassembly and installation are extremely convenient.
