Description

Technical Field

[0001] This utility model relates to an evaporation device, and more particularly to an optimized heat exchange evaporation device for a condensing unit in a supermarket freezer, belonging to the technical field of condensing units. Background Technology

[0002] The condensing unit of a supermarket freezer mainly consists of a compressor, condenser, throttling device, and evaporator. Through four cycles of compression, condensation, throttling, and evaporation, it transfers heat from the inside of the freezer to the external environment, maintaining a low temperature. The condensing unit is characterized by high efficiency, energy saving, stability, and reliability. It can be flexibly configured according to the freezer's usage scenario and needs, and is widely used in supermarkets, convenience stores, and other places to provide a suitable storage environment for fresh food, beverages, and other goods, ensuring product quality and freshness.

[0003] Currently, portable commercial freezers on the market have many shortcomings in defrost water treatment. Manually emptying the defrost water relies on manual operation, and if not handled promptly, it can easily overflow, leading to slips, short circuits, and other safety accidents. While electric heating for evaporating defrost water eliminates the need for manual intervention, the process consumes a large amount of electricity, significantly increasing the freezer's power consumption and raising operating costs. The method of using evaporation paper to absorb water and then accelerating evaporation with cold air is limited by physical evaporation efficiency, resulting in slow evaporation and unsatisfactory practical application. Therefore, this paper proposes an optimized heat exchange and evaporation device for the condenser unit of a supermarket freezer. Utility Model Content

Detailed Implementation

[0025] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] like Figures 1-4As shown, this utility model embodiment provides an optimized heat exchange and evaporation device for a condenser unit in a supermarket freezer, including a condenser assembly 20. The condenser assembly 20 includes a water collection tank 21, a first water absorption plate 22, a first support 23, a first evaporation plate 24, a second water absorption plate 26, a second support 27, a second evaporation plate 28, a fixed base 210, a condenser 211, a support plate 212, a drive box 213, a fan 214, and a compressor 216.

[0028] A first water-absorbing plate 22 is fixedly connected to the inner wall of the water collection tank 21. A first bracket 23 is fixedly connected to the top of the first water-absorbing plate 22. A first evaporation plate 24 is fixedly connected to the inner wall of the first bracket 23. A second water-absorbing plate 26 is fixedly connected to the inner wall of the water collection tank 21. A second bracket 27 is fixedly connected to the top of the second water-absorbing plate 26. A second evaporation plate 28 is fixedly connected to the inner wall of the second bracket 27. A fixing seat 210 is provided in front of the first evaporation plate 24. A condenser 211 is installed on the inner wall of the fixing seat 210. A support plate 212 is provided in front of the condenser 211. The support plate 212 is located behind... A drive box 213 is fixedly connected to the surface. A fan 214 is installed on the front surface of the support plate 212. A compressor 216 is located in front of the fan 214. Defrosting water droplets fall into the water collection tank 21. Water is absorbed from the water collection tank 21 by the water absorption plate and flows to the evaporation plate for evaporation through capillary action. The evaporation plate is made of absorbent paper material. There is a certain angle between adjacent absorbent papers, thereby changing the airflow path and causing it to flow in an S-shape between the evaporation plates. Dust in the air, due to its large weight, will reach the absorbent paper during the flow and adhere to it, thus preventing it from accumulating on the condenser 211.

[0029] In this embodiment, specifically: the outer side wall of the first bracket 23 is symmetrically and fixedly connected with a first sealing strip 25.

[0030] In this embodiment, specifically: a second sealing strip 29 is symmetrically fixedly connected to the outer side wall of the second bracket 27. The sealing strip is used to prevent air from passing through the evaporation device through the gap.

[0031] In this embodiment, specifically, the compressor 216 is installed on one side of the mounting base 215.

[0032] In this embodiment, specifically: the compressor 216 is located behind the second evaporator plate 28, and heat dissipation fins are fixedly connected to the outer wall of the compressor 216 to increase the heat exchange area of ​​the compressor 216 shell.

[0033] In this embodiment, specifically: the condensation component 20 is provided with a main body component 10 on its exterior, and the main body component 10 includes a housing 11 and a fixing frame 12;

[0034] The housing 11 has fixed frames 12 symmetrically fixed at both ends, which are used to fix the filter screen.

[0035] In this embodiment, specifically: a first filter screen 13 and a second filter screen 14 are fixedly connected to one side of the two fixed frames 12 respectively. The first filter screen 13 and the second filter screen 14 are used to prevent large particulate pollutants from entering the interior of the evaporation device.

[0036] In this embodiment, specifically: the water collection tank 21 is fixedly connected to the bottom of the inner side wall of the housing 11, and the fixing seat 210, the support plate 212 and the mounting seat 215 are fixedly connected to the inner side wall of the housing 11.

[0037] In operation, this invention works as follows: When the system is running, the fan 214 rotates, drawing air in from one end of the casing 11. At this point, the air temperature is T0. The air first passes through the first filter 13, filtering out large particulate pollutants such as lint and dust. Then, it reaches the first evaporator 24, which adsorbs small dust particles and evaporates the water absorbed from the water collection tank 21 by the first water absorption plate 22, lowering the air temperature to T1. The air then reaches the condenser 211, exchanging heat with it and absorbing its heat, raising the air temperature to T2. Finally, the air reaches the compressor 216, exchanging heat with it, further increasing the temperature to T3. Simultaneously, it carries away the heat emitted by the compressor 216, preventing it from overheating and damaging the compressor 216. The further heated airflow goes to the second evaporator plate 28, where the high-temperature air exchanges heat with the second evaporator plate 28, heating the water temperature and thus accelerating the evaporation of the defrost water. The air temperature drops again to T4 and is finally discharged from the other end of the casing 11. By enclosing the fan 214 and compressor 216 in the middle of the evaporation mechanism, some noise can be absorbed, reducing the noise of the system operation.

[0038] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
