Description

Technical Field

[0001] This utility model relates to the technical field of evaporators, and in particular to a structure for a refrigeration evaporator. Background Technology

[0002] Evaporators are core heat exchange components in refrigeration systems, air conditioning systems, and industrial heating or concentration equipment. Their core function is to absorb heat through the evaporation of refrigerant, thereby exchanging heat with the surrounding medium to achieve purposes such as cooling, concentration, or temperature reduction. There are many types of evaporators, among which finned evaporators are quite common. Finned evaporators are evaporators that enhance heat exchange efficiency by adding fins to the surface of heat exchange tubes. They are widely used in refrigeration equipment such as air conditioners, refrigerators, cold storage, dehumidifiers, and freezers. Therefore, a freezer evaporator structure is particularly needed.

[0003] However, most existing evaporator structures for refrigeration units are one-piece finned evaporators. When some parts of the finned evaporator malfunction, it is difficult to repair and replace them quickly. Secondly, because the finned evaporator needs to exchange heat with the air, its surface is prone to dust accumulation, which will affect the heat exchange efficiency.

[0004] To address the aforementioned issues, a search revealed a patent with publication number CN 111595070 B that discloses a finned evaporator. The patent states that "existing evaporators often face defrosting difficulties when placed outdoors in frosty conditions. Moreover, they merely absorb heat from the air in a normal external environment and cannot actively improve airflow, resulting in low heat absorption efficiency." In this application, the through holes on adjacent fin bodies are staggered vertically and horizontally. The staggered distribution of airflow, both vertically and horizontally, prevents air from directly flowing from one evaporator fin to another through the through-holes. Instead, air first acts on the fin body, where it is absorbed by the refrigerant pipes. Preferably, the heating assembly includes a heating wire and a heating strip. The heating wire is installed on the outer surface of the fin body, and the heating strip is installed inside the fin flap. The heating wire design improves the defrosting effect, while the heating strip design evenly distributes heat across the entire fin flap through heat conduction for comprehensive defrosting. The heating assembly includes a heating wire and a heating strip, with the heating wire installed on the outer surface of the fin body. The heating belt is installed inside the finned flap. The heating wire design is intended to improve the defrosting effect. The heating belt design distributes heat evenly across the entire finned flap through heat conduction, enabling comprehensive defrosting. The heating belt has a wavy distribution inside the finned flap. This wavy design aims to better heat the finned flap and improve defrosting efficiency. A vibration motor is installed on the finned flap, located on the side away from the rotation axis. This vibration motor design allows for vibration operation of the finned flap, improving defrosting efficiency. However, it makes maintenance, replacement, or regular cleaning of the evaporator very troublesome.

[0005] In light of this, in-depth research into the aforementioned issues led to the creation of this case. Utility Model Content

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 This utility model provides a technical solution: a refrigerator evaporator structure, including a mounting base 1, an evaporator tube 2 fixedly mounted at one end of the mounting base 1, a first receiving groove 3 formed on the inner wall of one side of the opening of the mounting base 1, a first spring 4 fixedly mounted inside the first receiving groove 3, a first locking block 5 fixedly connected to the other end of the first spring 4, a first connecting rod 6 fixedly mounted on the side surface of the first locking block 5 connected to the first spring 4, a first mounting block 7 embedded in the opening of the mounting base 1, a first locking groove 8 formed on one side surface of the first mounting block 7, and a first mounting tube 2 fixedly mounted on one side surface of the first mounting block 7. The device has a first fin 9, a connecting plate 10 fixedly mounted on one side surface of the first fin 9, a second receiving groove 11 formed on the inner wall of the opening side of the connecting plate 10, a second spring 12 fixedly mounted inside the second receiving groove 11, a second locking block 13 fixedly connected to the other end of the second spring 12, a second connecting rod 14 fixedly mounted on one side surface of the second locking block 13 and the second spring 12, a second mounting block 15 embedded in the opening of the connecting plate 10, a second slot 16 formed on one side surface of the second mounting block 15, and a second fin 17 fixedly mounted on one side surface of the second mounting block 15. The mounting base 1, evaporator tube 2, first receiving slot 3, first spring 4, first locking block 5, first connecting rod 6, first mounting block 7, first slot 8, first fin 9, connecting plate 10, second receiving slot 11, second spring 12, second locking block 13, second connecting rod 14, second mounting block 15, second slot 16, and second fin 17 are arranged such that when installing the first fin 9, the first mounting block 7 is inserted into the opening of the mounting base 1. When the first mounting block 7 is fully inserted into the opening, the first locking block 5 is fixed in the first slot 8 under the elastic force of the first spring 4. At this time, the first receiving slot 1, second spring 2, first locking block 3, first connecting rod 4, first connecting rod 5, first connecting rod 6, first mounting block 7, first slot 8, first fin 9, connecting plate 10, second receiving slot 11, second spring 12, second locking block 13, second connecting rod 14, second mounting block 15, second slot 16, and second fin 17 are connected. The mounting block 7 will be fixed in the mounting base 1. After the installation of the first fin 9 is completed, the second mounting block 13 will be fixed in the second slot 16 using the same principle when installing the second fin 17. The second mounting block 15 will then be fixed in the opening of the connecting plate 10. In this way, the first fin 9 and the second fin 17 can be connected together through the snap-fit ​​interface 18. When it is necessary to disassemble the first fin 9 and the second fin 17, it is only necessary to pull the first connecting rod 6 and the second connecting rod 14 to complete the disassembly. This modular design makes installation and disassembly very convenient, and facilitates maintenance, replacement and regular cleaning.

[0024] Furthermore, the first locking block 5 and the first locking groove 8 are sized to match. The first locking block 5 and the first mounting block 7 form a locking structure through the first locking groove 8. Through the arrangement between the first locking block 5 and the first locking groove 8, when the first locking block 5 is fixed in the first locking groove 8, the first mounting block 7 will be fixedly installed in the opening of the mounting base 1, and the first fin 9 will be fixedly installed on the mounting base 1. The installation of the first fin 9 is very simple and convenient.

[0025] Furthermore, the first locking block 5 forms a telescopic structure with the mounting base 1 through the first spring 4. With the setting of the first spring 4, when the first connecting rod 6 is not under force, the first locking block 5 will be fixed in the first locking groove 8 under the elastic force of the first spring 4, thereby fixing the first mounting block 7 in the mounting base 1.

[0026] Furthermore, the second locking block 13 and the second locking slot 16 are sized to match. The second locking block 13 and the second mounting block 15 form a locking structure through the second locking slot 16. With the setting of the second locking block 13 and the second locking slot 16, when the second locking block 13 is fixed in the second locking slot 16, the second mounting block 15 will be fixed in the opening of the connecting plate 10, and the second fin 17 can be fixedly locked together with the first fin 9. The cooperation between the second fin 17 and the first fin 9 further improves the heat exchange efficiency.

[0027] Furthermore, the second locking block 13 forms a telescopic structure with the connecting plate 10 through the second spring 12. With the setting of the second spring 12, when the second connecting rod 14 is not under force, the second locking block 13 will be fixed in the second slot 16 under the elastic force of the second spring 12, thereby fixing the second mounting block 15 in the connecting plate 10.

[0028] Furthermore, the first fin 9 and the second fin 17 can be connected together by snap-fit. With the first fin 9 and the second fin 17 connected together, it is easy to disassemble and maintain without affecting the heat exchange efficiency.

[0029] Furthermore, a snap-fit ​​interface 18 is provided through the surface of the first fin 9. The snap-fit ​​interfaces 18 are equally spaced on the surface of the first fin 9. Through the snap-fit ​​interface 18, the second fin 17 can be quickly snapped together with the first fin 9, which is simple and convenient to operate.

[0030] Working principle: When installing the first fin 9, the first mounting block 7 is inserted into the opening of the mounting base 1. When the first mounting block 7 is fully inserted into the opening, the first locking block 5 will be fixed in the first slot 8 under the elastic force of the first spring 4. At this time, the first mounting block 7 will be fixed in the mounting base 1, and the installation of the first fin 9 is completed. When installing the second fin 17, the same principle is used to fix the second locking block 13 in the second slot 16. The second mounting block 15 will be fixed in the opening of the connecting plate 10. In this way, the first fin 9 and the second fin 17 can be connected together through the locking interface 18. When it is necessary to disassemble the first fin 9 and the second fin 17, it is only necessary to pull the first connecting rod 6 and the second connecting rod 14 to complete the disassembly.
