Description

Technical Field

[0001] This utility model belongs to the technical field of refrigerator components, and in particular relates to a refrigerator evaporator that is easy to install. Background Technology

[0002] The evaporator is the device in a refrigeration system that outputs cooling capacity. Its main function is heat absorption; as the refrigerant evaporates inside the evaporator, it absorbs heat from the surrounding environment, thereby lowering the internal temperature of the refrigerator and achieving the purpose of cooling. Through the heat absorption of refrigerant evaporation, the heat inside the refrigerator is carried away, achieving a cooling effect and keeping food fresh or frozen. However, it still has the following drawbacks in practical use:

[0003] During the installation of the refrigerator evaporator, the evaporator is directly welded to the condensing equipment through a joint and then installed through a corresponding structure. However, the installation operation is relatively troublesome and the use is not convenient.

[0004] Secondly, during operation, one side of the heat exchange fins of the refrigerator evaporator is attached to the inner wall of the refrigerator. As it operates, air convection is affected, resulting in insufficient heat exchange by the evaporator. Utility Model Content

[0005] The purpose of this utility model is to provide a refrigerator evaporator that is easy to install. By setting up a fixing bracket 1, heat exchange fins, evaporation tube, fixing bracket 2, and fixing groove, it solves the problems of inconvenient installation and operation of refrigerator evaporators and insufficient heat exchange of evaporators.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a refrigerator evaporator that is easy to install. It includes a first mounting bracket, heat exchange fins, an evaporator tube, a second mounting bracket, and a mounting groove. Several parallel vertical heat exchange fins are fixed to one side of both the first and second mounting brackets. An evaporator tube is fixed to the front and rear portions of each heat exchange fin. A first mounting plate is fixed to the bottom edge of the first mounting bracket away from the heat exchange fins, and a second mounting plate is fixed to the top edge of the second mounting bracket away from the heat exchange fins. Mounting grooves are fixed to the sides of both the first and second mounting plates away from the heat exchange fins. During operation, the heat exchange fins are connected via the first and second mounting brackets. The heat exchange fins increase the heat exchange area of ​​the refrigerant in the evaporator tube, allowing the evaporating refrigerant to be transported through the evaporator tube. The mounting grooves hold adhesive strips for installation in the refrigerator.

[0008] Furthermore, the interior of the first and second fixing frames is hollow, and the two sides, top and bottom of the first and second fixing frames are open. When the first and second fixing frames are working, the heat exchange fins are suspended in the refrigerator.

[0009] Furthermore, a connecting plate is fixed at each of the two lower corners of the fixed plate near the heat exchange fins, and a support frame is fixed at the ends of the two connecting plates away from the fixed plate to support the heat exchange fins in the refrigerator.

[0010] Furthermore, fixing holes are provided in the heat exchange fins corresponding to the positions of the two evaporation tubes. Both evaporation tubes are fixed in the heat exchange fins. The bottom of all the heat exchange fins is fixed to the top of the support frame. The fixing holes on the heat exchange fins fix the evaporation tubes.

[0011] Furthermore, the lower ends of the two evaporating tubes are fixedly connected to a connecting bend, and the upper end of each evaporating tube is fixedly connected to a fixed joint, so that the evaporating tubes are connected to the heat exchange equipment.

[0012] Furthermore, the fixing groove has an opening on its rear side and is made of a flexible material. An adhesive strip is fixed inside the fixing groove so that the evaporator can be connected to the evaporator.

[0013] This utility model has the following beneficial effects:

[0014] This invention solves the problem of inconvenient installation of refrigerator evaporators by setting up a first fixing bracket, heat exchange fins, a second fixing bracket, and a fixing groove. During evaporator installation, the back of the heat exchange fins is directly aligned with the inner wall of the refrigerator, and the first fixing plate, connecting plate, and support bracket are supported on the lower part of the inner wall of the refrigerator. The evaporator tube is pushed and the fixing groove is pressed, so that the adhesive strip contacts the inner wall of the refrigerator and is adhered to the inner wall. This makes the entire evaporator stably installed in the refrigerator, making the installation of refrigerator evaporators more convenient.

[0015] This invention solves the problem of insufficient heat exchange in refrigerator evaporators by setting up a first fixing bracket, heat exchange fins, evaporator tubes, and a second fixing bracket. After the evaporator is installed inside the refrigerator, the refrigerant enters through a fixed joint on one evaporator tube, then passes through a connecting bend and is transported to another evaporator tube. Finally, it is transported to the refrigerant condensation equipment through a fixed joint. During the heat absorption process, the heat exchange fins absorb heat from inside the refrigerator. At the same time, the fixing plate, connecting plate, and support frame at the bottom of the first fixing bracket work together to suspend the heat exchange fins inside the refrigerator, ensuring good heat exchange within the refrigerator and making the heat exchange of the refrigerator evaporator more complete.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0026] Please see Figure 1-5This utility model is a refrigerator evaporator that is easy to install. It includes a mounting bracket 1, heat exchange fins 2, evaporator tubes 3, a second mounting bracket 4, and a mounting groove 5. Several parallel vertical heat exchange fins 2 are fixed to one side of both mounting brackets 1 and 4. When mounting brackets 1 and 4 are installed together, the heat exchange fins 2 are suspended to ensure air convection, improve heat exchange efficiency, and allow the heat exchange fins 2 to fully exchange heat. Evaporator tubes 3 are fixed to the front and rear parts of all heat exchange fins 2. The refrigerant is transported through the tube, causing it to evaporate and absorb heat in the evaporator tube 3. A fixing plate 101 is fixed at the bottom of the fixing bracket 1 away from the edge of the heat exchange fin 2. The fixing plate 101 fixes the fixing groove 5 on the fixing bracket 1. A fixing plate 401 is fixed at the top of the fixing bracket 4 away from the edge of the heat exchange fin 2. The fixing plate 401 fixes the fixing groove 5 on the side away from the heat exchange fin 2. The fixing groove 5 fixes the adhesive strip 501 in the fixing groove 5.

[0027] Specifically, the interior of the first fixing frame 1 and the second fixing frame 4 is hollow, and the sides, top and bottom of the first fixing frame 1 and the second fixing frame 4 are open. By being hollow, the first fixing frame 1 and the second fixing frame 4 support the heat exchange fins 2 while reducing the contact area.

[0028] Furthermore, a connecting plate 102 is fixed at the two lower corners of the fixed plate 101 near the heat exchange fin 2. The ends of the two connecting plates 102 away from the fixed plate 101 are jointly fixed with a support frame 103. The connecting plate 102 connects the support frame 103 to the fixed plate 101, and the support frame 103 supports the heat exchange fin 2.

[0029] Furthermore, fixing holes 201 are provided in the heat exchange fins 2 corresponding to the positions of the two evaporation tubes 3. Both evaporation tubes 3 are fixed in the heat exchange fins 2. The bottom of all heat exchange fins 2 is fixed to the top of the support frame 103. When the heat exchange fins 2 are working, the fixing holes 201 fix the evaporation tubes 3.

[0030] Furthermore, the lower ends of the two evaporator tubes 3 are connected by a connecting bend 302, and the upper end of each evaporator tube 3 is connected by a fixed connector 301. During operation, the evaporator tubes 3 are interconnected through the connecting bend 302 and connected to the refrigerant condensation system through the fixed connector 301.

[0031] The operation process of this embodiment is as follows: During operation, after the evaporator is installed in the refrigerator, the refrigerant enters from the fixed joint 301 on one evaporator pipe 3, and after passing through the connecting bend 302, it is transported to another evaporator pipe 3 and then to the refrigerant condensing equipment through the fixed joint 301. During the heat absorption process, the heat exchange fins 2 absorb the heat inside the refrigerator. At the same time, with the cooperation of the fixed plate 101, connecting plate 102 and support frame 103 at the bottom of the fixed frame 1, the heat exchange fins 2 are suspended in the refrigerator, ensuring that the heat exchange fins 2 can exchange heat well inside the refrigerator. Specific Implementation Example 2

[0032] Please see Figure 1 , 3 Based on the first specific embodiment, the fixing groove 5 has an opening on the rear side and is made of flexible material. An adhesive strip 501 is fixed inside the fixing groove 5. When the fixing groove 5 is working, the adhesive strip 501 is bonded to the inner wall of the refrigerator, fixing the heat exchange fins 2 on the inner wall of the refrigerator.

[0033] The operation process of this embodiment is as follows: During operation, when installing the evaporator, the rear side of the heat exchange fins 2 is directly aligned with the inner wall of the refrigerator, and the fixing plate 101, connecting plate 102 and support frame 103 are supported on the lower part of the inner wall of the refrigerator. The evaporator tube 3 is pushed and the fixing groove 5 is squeezed so that the adhesive strip 501 contacts the inner wall of the refrigerator and is adhered to the inner wall of the refrigerator, so that the entire evaporator is stably installed in the refrigerator. Under the subsequent installation and setting of equipment, the position of the evaporator is restricted. The adhesive strip 501 uses a low temperature resistant adhesive to ensure long-term stable adhesion in the refrigerator environment.
