Description

Technical Field

[0001] The utility model relates to the technical field of electronic refrigeration, in particular to the technical field of electronic refrigeration equipment which adopts a circulating water cooling heat dissipation method. Background Art

[0002] Refrigeration equipment is a device that artificially lowers the temperature to perform a freezing process. It is used to preserve food and prepare cold food. Common refrigeration equipment includes compressor refrigeration and electronic refrigeration. Both of these conventional technologies have corresponding disadvantages. The problems with compressor refrigeration are: 1. The principle of compressor refrigeration is to increase the refrigerant from low pressure to high pressure and make the refrigerant circulate continuously, so there is a sealed refrigerant in the equipment, so the equipment is prone to refrigerant leakage during long-distance transportation; 2. Compressor refrigeration requires refrigerant / coolant. Because it involves a high-pressure compression seal design, it cannot be transported by air, which is limited in logistics; 3. There will be condensed water in this process, and the problem of condensed water is difficult to eliminate, resulting in a relatively high product failure rate. The problems with electronic refrigeration are: 1. The current temperature of electronic refrigeration is not low enough. One reason is that the designed ambient temperature is too high, which leads to insufficient refrigeration performance. Another reason is that when designing cold water, normal temperature water will be added at the same time, which will cause normal temperature water to mix with low temperature water, resulting in temperature runaway. 2. The refrigeration system has insulation power, which is noisy and wastes energy, and is not environmentally friendly. 3. Insulation cotton or foam will be used on the outside of the cold tank to store condensed water. Because of the heat dissipation structure on the structure, the system cannot use other high-quality insulation structures. 4. The required volume is very large. The cold water utilization rate of general space is only 50%~60%. Therefore, when the water output is determined, the volume of the system is very large. For example, if the water output is 500ml, the internal volume of the ice tank needs to be 800~1000ml. Summary of the invention

[0003] In view of the above technical problems, the utility model proposes a refrigeration device adopting circulating water cooling heat dissipation technology. The refrigeration device adopts electronic refrigeration, does not need to use refrigerant and does not have leakage problems. Because circulating water cooling is adopted, the physical space separation of the ice chamber and the heat dissipation system can be achieved, so the ice chamber can be foamed and insulated as a whole to avoid the problem of condensed water. At the same time, the ice chamber is designed to retain ice, further improving the space utilization rate of the ice chamber.

[0017] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments, examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0018] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0019] Please refer to the attached Figure 1The utility model adopts electronic refrigeration instead of compressor refrigeration, so no refrigerant or coolant is needed, and there is no need to worry about the problem of coolant leakage. Instead of using the existing method of using a fan to directly dissipate heat from the refrigeration plate, the refrigeration plate can be wrapped with a heat preservation device as a whole, so that condensation water will not be generated, and the technical problem of long-term condensation water growing mold is avoided.

[0020] Please refer to the attached Figure 1 and attached Figure 2 , which shows the whole refrigeration device involved in the utility model, and the refrigeration device includes an ice container 10, a heat sink 20 and a controller (not shown), wherein the ice container 10 includes a refrigeration container 11 and a refrigeration sheet 12, and the refrigeration sheet 12 is directly attached to the refrigeration container 11. The refrigeration sheet 12 is a well-known technology in the industry and is a standard part for refrigeration through electric energy. The heat sink 20 is a device for directly dissipating heat from the refrigeration sheet 12.

[0021] The attached figure shows that the heat dissipation device 20 includes a heat dissipation water circuit plate 21, a water pump 22, a cold radiator 23 and a circulating water tank 23, wherein the heat dissipation water circuit plate 21 is connected to the hot end of the refrigeration plate 12 through thermal conductive silica gel, and the heat dissipation water circuit plate 21, the cold radiator 23, the circulating water tank 24 and the water pump 22 are connected in series through pipes to form a water circulation loop; the water pump 22 provides power for the heat dissipation liquid circulating therein, drives the heat dissipation liquid to circulate through the heat dissipation water circuit plate 21, and the liquid flows through the heat dissipation water circuit plate 21 to the cold radiator 23, and the cold radiator 23 is a heat dissipation structure with a fan to dissipate heat from the heat dissipation liquid flowing through it.

[0022] The radiator 23 is preferably a copper tube copper fin radiator, a copper tube aluminum fin radiator or an aluminum tube aluminum fin radiator, and no further limitation is made here as long as the heat dissipation demand of air cooling for liquid can be met.

[0023] The circulating water tank 24 provides circulating cooling liquid for the system, realizes water vapor separation and prevents the water pump from pumping air.

[0024] The heat dissipation device as a whole utilizes a water pump 22 to achieve forced convection heat exchange, and the heat at the hot end of the refrigeration plate 12 is taken away by the circulating heat dissipation liquid. The temperature of the liquid coming from the hot end of the refrigeration plate 12 of the ice chamber is the highest temperature in the entire system. The heat dissipation liquid directly enters the radiator 23 through the heat dissipation water plate 21, and the heat dissipation liquid is cooled by the radiator 23. The cooled heat dissipation liquid enters the circulating water tank 24 to achieve water vapor separation.

[0025] Please refer to the attached Figure 2 and attached Figure 3The refrigeration container 11 of the ice chamber is shown therein, and the refrigeration container 11 includes an aluminum body 13, an upper cover plate 14 and a lower cover plate 15. A plurality of partitions 131 are arranged in the middle of the aluminum body 13. The partitions 131 in the aluminum body 13 and the upper and lower cover plates are combined together to form a rotating liquid flow channel structure.

[0026] The outer wall of the refrigeration container 11 of the ice chamber is provided with a refrigeration plate 12, and a partition 131 is provided inside. The direction of the partition 131 is installed in a normal direction to the installation direction of the refrigeration plate 12. The purpose of such installation is that the liquid flows from the hot end to the cold end of the refrigeration plate 12 layer by layer. The water just injected into it is at the end with the relatively highest temperature in the refrigeration container 11, and the temperature gradually decreases as the liquid flows to the outlet direction. In this way, the temperature is reduced layer by layer and the temperature channeling phenomenon caused by the injection of normal temperature water can be avoided.

[0027] The upper cover plate 14 is provided with a flow channel partition corresponding to the partition plate 131 and a water inlet 141 connected to the flow channel of the refrigeration container, and the lower cover plate 15 is provided with a corresponding partition 152 and a water outlet 151 .

[0028] An anti-icing NTC 153 is provided in the center of the lower cover plate 15 near the flow channel separator. A cold water control NTC 154 is provided on the lower cover plate 15 corresponding to the lower part of the water inlet 141. The signals of the anti-icing NTC 153 and the cold water control NTC 154 are connected to the controller.

[0029] When the room temperature water that needs to be refrigerated enters the refrigeration container 11 from the water inlet 141 and moves along the flow channel, the utilization rate of the cold water is improved, which can reach more than 80% of the cold water utilization rate, and the volume of the ice tank can be further reduced. At the same time, the cold water control NTC154 is set in the middle of the flow channel, at the lower end of the water inlet 141, to ensure that the temperature of the ice tank is low enough when the ice tank is shut down. An anti-ice blocking NTC 153 is set at the dividing piece close to the flow channel. The characteristic is that it is closer to the dividing piece of the flow channel and closer to the refrigeration plate. The detected temperature will be lower than the cold water control NTC 154, so the cold water control NTC 154 can set a lower temperature to achieve refrigeration control with lower water temperature, and even retain a certain amount of ice inside the refrigeration container 11 of the ice tank to ensure that the normal temperature water entering the outlet water can be quickly cooled, ensure a single continuous endurance, and shorten the time difference between two refrigerations, so that the cold water utilization rate can be increased to more than 150%. The reason is that the melting of ice can absorb a lot of heat to achieve a utilization rate of more than 100%.

[0030] The refrigeration temperature of existing electronic refrigeration equipment is not low enough. On the one hand, the ambient temperature is too high in the design, resulting in insufficient refrigeration performance. On the other hand, the ice container is an integral structure design. When the water is discharged, it will start to replenish water. Once the water in the normal temperature water container is replenished, the temperature will immediately jump, resulting in insufficient refrigeration temperature. The refrigeration container 11 in the improved ice container of the present application adopts aluminum stretched plate to form a multi-layer rotating flow structure, and a forced water cooling heat dissipation device is set outside the ice container to achieve better environmental adaptability and overcome the problem of temperature jump when replenishing water.

[0031] The heat dissipation waterway plate 21 includes a waterway pipe plate body 211, a waterway plate plug 212 and a heat dissipation and thermal conductive seat body 213. A plurality of hollow through-tube bodies are arranged in the same direction in the waterway pipe plate body 211. Both ends of the tube bodies are connected and conducted through the waterway plate plug 212 and the heat dissipation and thermal conductive seat body 213 to form a sequentially connected flow channel. A water inlet end 214 and a water outlet end 215 are respectively provided at both ends of the heat dissipation and thermal conductive seat body 213.

[0032] Because the heat dissipation device 20 is designed with a heat dissipation water path plate 21 directly attached to the hot end of the refrigeration plate 12, the heat is taken away by the heat dissipation liquid and the temperature is cooled at the radiator 23. Therefore, the ice tank can be foamed and wrapped with an insulation structure as a whole, and there is no need to reserve an additional heating part for heat dissipation. In this way, the overall foaming insulation prevents moisture from entering and eliminates the generation of condensed water, thereby solving the problem of mold and odor caused by the long-term presence of condensed water.

[0033] In addition, the existing refrigeration equipment requires a large volume, and the cold water utilization rate of the general space is only 50%~60%. Therefore, when the water output is determined, the design volume of the system is very large. For example, if the water output is 500ml, the system volume needs to be 800~1000ml, which cannot adapt to the design of the miniaturized volume of the system. However, the spiral flow channel used in this solution improves the cold water utilization rate of the system, and the system design can freeze for cold storage, so the output of ice water is further improved.

[0034] Because the refrigeration container of the present solution is made of aluminum material as a whole, it has good thermal conductivity. When the refrigeration plate 12 is set on the refrigeration container, the entire refrigeration container can be turned into a "refrigerator". Therefore, local ice formation in the refrigeration container will not affect the overall refrigeration efficiency. Moreover, the lowest temperature of the system is at the position closest to the refrigeration plate. Placing the anti-ice blockage NTC 153 at the position closest to the fin and also closest to the refrigeration plate will measure the lowest temperature of the entire system. Therefore, the water outlet temperature must be higher than this temperature, and the problem of ice blockage and inability to discharge water will not occur. Therefore, the system can be designed to retain a certain ice mode.

[0035] The water pump in the heat dissipation device provides power for the flow of the heat dissipation liquid in the circulating water circuit, and the water pump is a diaphragm pump or an impeller pump.

[0036] The refrigeration equipment involved in the utility model adopts electronic refrigeration plates for refrigeration, does not need to use refrigerant, and is configured with a circulating water-cooled heat dissipation device near the refrigeration plates, thereby realizing the physical space separation of the ice chamber and the heat dissipation system, overcoming the problems of generating condensed water and the problem that the ice chamber cannot be foamed and insulated as a whole to affect the refrigeration efficiency; at the same time, a rotating flow channel is designed for the internal structure of the refrigeration container to avoid temperature leakage caused by water replenishment, thereby improving the refrigeration efficiency and obtaining a lower refrigeration temperature.

Although the utility model is disclosed as a preferred embodiment as above, it is not used to limit the utility model.
