Description

Technical Field

[0001] This utility model belongs to the field of evaporator-related technical technology, specifically relating to a new structure that improves the defects of natural defrosting in evaporators. Background Technology

[0002] Natural defrosting of cold storage evaporators commonly employs defrosting methods such as electric defrosting, water defrosting, hot gas defrosting, and natural defrosting. Natural defrosting achieves defrosting through natural air circulation, requiring no additional energy consumption. It only requires circulating air above 0°C within the cold storage to allow the frost layer to melt and fall off naturally, without affecting the items inside the cold storage. It is both green and environmentally friendly, reduces operating costs, and is simple to operate and easy to maintain.

[0003] However, under some extreme climatic conditions, such as sustained low temperature or high humidity, frost will accumulate excessively. In this case, the natural defrosting effect will not be ideal, resulting in incomplete defrosting. In addition, the natural defrosting effect is slow, generally requiring several days to several weeks to complete defrosting, and cannot achieve rapid defrosting. Utility Model Content

[0004] The purpose of this invention is to provide a new structure that improves the defects of natural defrosting of evaporators, so as to solve the problem mentioned in the background art that under some extreme climatic conditions, such as continuous low temperature or high humidity environment, too much frost will accumulate, and the natural defrosting effect will not be ideal, resulting in incomplete defrosting. In addition, the natural defrosting effect is slow, generally requiring several days to several weeks to complete defrosting, and cannot achieve rapid defrosting.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a new structure for improving the defects of natural defrosting in evaporators, comprising an evaporator body;

[0006] An evaporator frame is provided on the outer side of the evaporator body, and mounting boxes are provided on the left and right sides of the evaporator body.

The openable door panel facilitates maintenance and cleaning of the evaporator's interior. The fan motor inside the door panel provides airflow power to ensure normal evaporator operation. The hinges and opening button make opening easy, and the three openable door panels arranged in an array can flexibly meet different needs. The cushioning cotton on the front of the air outlet panel provides cushioning and sealing, while the positioning grooves in the outer ring array help ensure accurate fit with the openable door panel, improving structural stability and sealing.

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figure 1-4 A novel structure for improving the defects of natural defrosting of evaporators is shown, comprising an evaporator body 1;

[0025] An evaporator frame 14 is provided on the outer side of the evaporator body 1. An installation box 15 is provided on the left and right sides of the evaporator body 1. A back hanger 16 is provided above the installation box 15. A base 17 is provided at the bottom of the evaporator frame 14. A fixing bracket 18 is provided at the bottom of the base 17.

[0026] An air outlet panel 3 is provided at the front of the evaporator body 1, and an openable door panel 2 is provided at the front of the air outlet panel 3. A fan motor 7 is provided inside the openable door panel 2.

[0027] A door hinge 4 is provided on the left side of the openable door panel 2, and a door opening button 5 is provided on the upper right corner of the outer side of the openable door panel 2. There are three openable door panels 2 in the array.

[0028] A buffer filling cotton 6 corresponding to the openable door panel 2 is provided at the front side of the air outlet panel 3, and a positioning groove 12 is provided in a ring array on the outer side of the buffer filling cotton 6.

[0029] A pressurizing cylinder 8 is installed at the top of the evaporator body 1, and a control button 9 is installed in the middle of the inside of the pressurizing cylinder 8.

[0030] An ejector 10 is provided on the right side of the cushioning filling cotton 6, and the ejector 10 is connected to the pressurizing cylinder 8 through the connecting pipe 11.

[0031] Heat dissipation fins 13 are provided inside the evaporator body 1, and lifting frames 20 are arranged on the outer side of the heat dissipation fins 13.

[0032] The lifting frame 20 is connected and fixed to the heat dissipation fins 13 via the telescopic rod 19, and the heat dissipation fins 19 are multiple combined connections.

[0033] The evaporator frame 14 is made of steel. The heat dissipation fins 13 and the telescopic rod 13 are welded together. The heat dissipation fins 13 are in close contact with the bottom evaporator body 1. The evaporator frame 14 is installed and fixed by the fixing bracket 18 and the back hanger 16.

[0034] In this embodiment, a specific implementation step of a new structure for improving the defects of natural defrosting of evaporators is as follows: the evaporator body 1 is installed in the required position using the back hanger 16 and the fixing bracket 18, ensuring a firm and stable installation. When the evaporator body 1 is working, the fan motor 7 drives airflow, which is discharged through the air outlet panel 3. The heat dissipation fins 13 inside the evaporator body 1 dissipate heat through heat exchange with the air, improving the working efficiency of the evaporator. When defrosting is required, the door panel opening button 5 is pressed, and the door panel can be opened. At this time, we can see the defrosting status inside the evaporator through the opened door panel, and clearly observe whether the defrosting work has been completed. Opening the door panel allows air to enter the evaporator more easily and circulate more smoothly, which can accelerate the defrosting speed of the evaporator and make defrosting more thorough and complete. If necessary, for areas where defrosting is incomplete, we can intervene externally, such as manually defrosting through the openable door panel, to improve the defrosting effect. When the openable door panel 2 and the air outlet panel 3 are difficult to open, the pressurizing cylinder 8 is activated. The pressurizing cylinder 8 pushes the ejector 10 through the connecting pipe 11, and the ejector 10 pushes open the openable door panel 2. When physical defrosting of the heat dissipation fins 13 is required, the lifting frame 20 can be lifted through the telescopic rod 19, thereby lifting the heat dissipation fins 13 for easy operation.

[0035] like Figure 1 As shown, an air outlet panel 3 is provided at the front of the evaporator body 1, an openable door panel 2 is provided at the front of the air outlet panel 3, a fan motor 7 is provided inside the openable door panel 2, a door hinge 4 is provided on the left side of the openable door panel 2, a door opening button 5 is provided at the upper right corner of the outer side of the openable door panel 2, and three openable door panels 2 are arranged in an array. A buffer filling cotton 6 corresponding to the openable door panel 2 is provided at the front of the air outlet panel 3, and a positioning groove 12 is provided in a ring array on the outer side of the buffer filling cotton 6. A pressurizing cylinder 8 is provided at the top of the evaporator body 1, a control button 9 is provided in the middle of the inside of the pressurizing cylinder 8, and an ejector 10 is provided at the right side of the buffer filling cotton 6. The ejector 10 is connected to the pressurizing cylinder 8 through a connecting pipe 11.

[0036] Preferably, the openable door panel 2 is designed to facilitate maintenance and cleaning of the evaporator interior. The fan motor 7 inside the door panel provides airflow power to ensure the normal operation of the evaporator. At the same time, the door panel hinges 4 and the door panel opening button 5 make opening operation convenient. The three openable door panels 2 arranged in an array can more flexibly meet different needs. The buffer filling cotton 6 on the front side of the air outlet panel 3 can play a buffering and sealing role. The positioning grooves 12 of the outer annular array help to accurately match with the openable door panels 2, improving the stability and sealing of the structure. The pressurizing cylinder 8 above the evaporator body 1, together with the ejector 10, is connected by the connecting pipe 11, which can effectively improve the defrosting efficiency during defrosting and ensure the performance of the evaporator. The control button 9 can conveniently control the operation of the pressurizing cylinder 8, making the operation simple and efficient.

[0037] like Figure 1-4 As shown, heat dissipation fins 13 are provided inside the evaporator body 1, and lifting frames 20 are arranged in an array on the outer side of the heat dissipation fins 13. The lifting frames 20 are connected and fixed to the heat dissipation fins 13 by telescopic rods 19. The heat dissipation fins 19 are multiple combined and connected.

[0038] Preferably, the heat dissipation fins 13 are located inside the evaporator body 1, which can effectively exchange heat and improve the heat dissipation efficiency of the evaporator, thereby ensuring the working performance of the evaporator. Multiple heat dissipation fins 13 are combined and connected to enhance the overall heat dissipation effect and can better adapt to different working needs. The lifting frame 20 arranged on the outer array is connected and fixed to the heat dissipation fins 13 through the telescopic rod 19. When it is necessary to physically defrost the heat dissipation fins 13, the lifting frame 20 can be lifted through the telescopic rod 19, thereby lifting the heat dissipation fins 13, breaking the structure of the outer frost, and facilitating defrosting operations.

[0039] like Figure 1-4 As shown, the evaporator frame 14 is made of steel, the heat dissipation fins 13 and the telescopic rod 13 are welded together, the heat dissipation fins 13 are in close contact with the bottom evaporator body 1, and the evaporator frame 14 is installed and fixed by the fixing bracket 18 and the back hanger 16.

[0040] Optionally, the evaporator frame 14 is made of outer steel material, which has high strength and stability, and can provide reliable support and protection for the evaporator body 1, extending the service life of the evaporator. The heat dissipation fins 13 and the telescopic rod 19 are welded together, which is firm and reliable and is not easy to loosen or fall off during operation, ensuring that the heat dissipation fins 13 can stably perform the heat dissipation function. The heat dissipation fins 13 are closely attached to the bottom evaporator body 1, which can improve the heat transfer efficiency and make the heat dissipation effect of the evaporator more significant. The evaporator frame 14 is installed and fixed by the fixing bracket 18 and the back hanger 16. The installation method is simple and convenient, and the fixing is firm, which can ensure that the evaporator remains stable during operation and is not easy to shake or shift.
