[0002] At present, for some compression refrigeration refrigerators, the surface temperature of the condenser can reach up to 90 °C when the compressor is running, and the surface temperature of the evaporator can reach up to -50 °C at most. The energy exchange is realized through the dual heat dissipation method of side cooling combined with a bottom-mounted condenser. The bottom-mounted heat dissipation is used to physically dissipate heat from the condenser through a cooling fan. Usually, the cooling fan needs to work continuously during the operation of the compressor, resulting in high energy consumption.

The long-distance wiring inside the box body has a high cost and there is a risk of wire breakage. Screws are required for fixing at the bottom steel, and wiring accidents often occur.

[0049] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0050] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such used data may be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. generally belong to the same category, and the number of objects is not limited. For example, the first object may be one or multiple. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally represents an "or" relationship between the associated objects before and after.

[0051] Next, the refrigeration device provided by the embodiments of the present application will be described in detail in conjunction with the accompanying drawings through specific embodiments and their application scenarios.

[0052] Figure 1 It is a schematic diagram of the component composition of the refrigeration device according to an embodiment of the present utility model. As Figure 1As shown in the figure, the refrigeration device 100 of the embodiment of the present utility model includes an evaporator 101, a condenser 102, and a cooling fan 103, and further includes: a cooling fan control circuit 200, which is used to obtain the surface temperature of the evaporator 101 and the surface temperature of the condenser 102, generate electric potential energy based on the temperature difference between the surface temperature of the evaporator 101 and the surface temperature of the condenser 102, and drive the cooling fan 103 to operate based on the electric potential energy.

[0053] It can be understood that the evaporator 101 can be a full liquid evaporator, a dry evaporator, a circulating evaporator, etc., which are metal coil or plate structures designed based on the heat exchange principle. Its surface is in direct contact with the refrigerant, and by absorbing the heat of the surrounding environment, the refrigerant is evaporated from a liquid state to a gaseous state, thereby achieving the refrigeration effect.

[0054] It can be understood that the condenser 102 can be a shell and tube condenser, a double pipe condenser, a spiral plate condenser, etc., which are metal tube shell or plate structures designed based on the heat exchange principle. A cooling medium, such as cooling water or air, flows inside it. By contacting the refrigerant vapor, the condenser transfers the heat in the refrigerant vapor to the cooling medium, causing it to condense into a liquid, thereby completing the heat discharge process in the refrigeration cycle and ensuring the efficient operation of the refrigeration device.

[0055] It can be understood that the cooling fan 103 can be an axial flow fan, a centrifugal fan or other types, which are mechanical devices that use a motor to drive the fan blades to rotate to generate air flow. When its blades rotate at high speed, it inhales the surrounding air and accelerates its flow to form a strong air flow. The cooling fan takes away the heat around the condenser 102 through the generated air flow, reduces the temperature of the condenser, ensures that the refrigerant can be more effectively condensed and recycled, thereby improving the cooling effect and efficiency of the entire refrigeration device.

[0056] In the above technical solution, through the cooling fan control circuit, the refrigeration device can obtain the surface temperatures of the evaporator and the condenser, thereby generate electric potential energy based on the difference between these two temperatures, and use the electric potential energy to drive the cooling fan, which can save the interface of the main control board of the refrigeration device, reduce the wiring length inside the box body of the refrigeration device, realize the drive and speed adaptive control of the cooling fan, and reduce the energy consumption of the refrigeration device.

[0057] Figure 2 It is a schematic diagram of the composition of some components of the refrigeration device according to an embodiment of the present utility model, as Figure 2 As shown in the figure, the cooling fan control circuit 200 of the refrigeration device 100 of the embodiment of the present utility model includes: a thermoelectric power generation component 201 and a temperature conduction component 202, and the thermoelectric power generation component 201 is electrically connected to the cooling fan 103 of the refrigeration device.

[0058] The thermoelectric power generation component 201 is used to obtain the surface temperature of the evaporator 101 of the refrigeration device and the surface temperature of the condenser 102 of the refrigeration device through the temperature conduction component 202, generate electric potential energy based on the temperature difference between the surface temperature of the evaporator 101 and the surface temperature of the condenser 102, and drive the cooling fan 103 to operate based on the electric potential energy;

[0059] The temperature conduction component 202 is used to conduct the temperature difference between the surface temperature of the evaporator 101 and the surface temperature of the condenser 102.

[0060] It can be understood that the thermoelectric power generation component 201 is a device that generates electric potential energy using temperature difference. It generates electric potential energy according to the temperature difference between the evaporator and the condenser. This electric potential energy can be directly used to drive the cooling fan 103, or after conversion, it can provide electrical energy to the cooling fan 103, thereby controlling the operation of the cooling fan, enabling the cooling fan 103 to automatically adjust its rotation speed according to the real-time temperature difference of the refrigeration device 100, and achieving an energy-saving and efficient cooling effect.

[0061] It can be understood that the temperature conduction component 202 is responsible for monitoring the surface temperatures of the evaporator 101 and the condenser 102, and transmitting this information to the thermoelectric power generation component 201. The temperature conduction component 202 can sense the temperature changes of the evaporator and the condenser and conduct the temperature.

[0062] In the above technical solution, the thermoelectric power generation component uses the temperature difference between the evaporator and the condenser to generate electric potential energy to drive the cooling fan, achieving efficient utilization and recovery of energy, and effectively reducing the power consumption of the refrigeration device.

[0063] Figure 3 It is one of the rear view schematic diagrams of the refrigeration device according to an embodiment of the present invention. As Figure 3 shown, the thermoelectric power generation component 201 of the refrigeration device 100 according to the embodiment of the present invention is electrically connected to the cooling fan 103.

[0064] It can be understood that, as Figure 3 shown, the thermoelectric power generation component 201 is electrically connected to the cooling fan 103. This connection method makes the structure of the refrigeration device more flexible, can adapt to different models and specifications of cooling fans, and ensures that the cooling fan can operate normally using the electric potential energy provided by the thermoelectric power generation component.

[0065] In the above technical solution, the thermoelectric power generation component and the cooling fan are electrically connected, enabling the electric potential energy generated by the thermoelectric power generation component to be used by the cooling fan. This connection method enables the thermoelectric power generation component to directly provide power to the cooling fan when generating electrical energy, without the need for additional power sources or conversion devices, improving the energy utilization efficiency of the refrigeration device.

[0066] Figure 4 It is the second rear view schematic diagram of the refrigeration device according to an embodiment of the present invention. As Figure 4 shown, the thermoelectric power generation component 201 of the refrigeration device 100 according to the embodiment of the present invention is integrated with the cooling fan 103.

[0067] It can be understood that the integration of the thermoelectric power generation component 201 and the cooling fan 103 is a design that combines the principles of thermoelectric power generation and pneumatic drive. The thermoelectric power generation component 201 and the cooling fan 103 are combined in one unit. The thermoelectric power generation component 201 generates electrical energy by using the temperature difference between the evaporator 101 and the condenser 102, and the cooling fan 103 is directly driven by this electrical energy without additional power supply.

[0068] In the above technical solution, the thermoelectric power generation component is integrated with the cooling fan. The thermoelectric power generation component is used as a part of the cooling fan, and the generated electric potential energy is directly utilized inside the cooling fan to drive the operation of the cooling fan, which can save the interface at the main control board end of the refrigeration device, reduce the wiring length inside the box body, realize the drive and rotational speed adaptive control of the cooling fan, and reduce the energy consumption of the refrigeration device.

[0069] Figure 5 It is the schematic diagram of the material selection of the thermoelectric power generation component of the refrigeration device according to an embodiment of the present invention. As Figure 5 shown, the material used for the thermoelectric power generation component 201 of the refrigeration device 100 according to the embodiment of the present invention is determined based on the temperature difference between the surface temperature of the evaporator 101 and the surface temperature of the condenser 102 of the refrigeration device.

[0070] The material used for the thermoelectric power generation component 201 is one of the following:

[0071] bismuth telluride or zinc telluride or bismuth sulfide;

[0072] silicon-germanium alloy;

[0073] lead telluride.

[0074] For different temperature differences between the surface temperature of the evaporator 101 and the surface temperature of the condenser 102, the thermoelectric power generation component 201 uses different thermoelectric materials, making the refrigeration device more efficient in energy utilization.

[0075] In some embodiments, when the temperature difference between the surface temperature of the evaporator 101 and the surface temperature of the condenser 102 is greater than 700, the thermoelectric power generation component 201 uses a high-temperature material system, and the high-temperature material system refers to a silicon-germanium alloy material that has good thermoelectric performance in the medium and high temperature ranges and is suitable for occasions that require a higher working temperature.

[0076] In some embodiments, when the temperature difference between the surface temperature of the evaporator 101 and the surface temperature of the condenser 102 is greater than 300 and less than 700, the thermoelectric power generation component 201 adopts a medium-temperature material system, namely lead telluride material.

[0077] In some embodiments, when the temperature difference between the surface temperature of the evaporator 101 and the surface temperature of the condenser 102 is less than 300, the thermoelectric power generation component 201 adopts a low-temperature material system, that is, a material that exhibits high thermoelectric efficiency at room temperature, such as bismuth telluride material commonly used in low-temperature thermoelectric power generation applications. At the same time, considering the price and thermoelectric conversion efficiency of the materials, zinc telluride and bismuth sulfide can also be used as alternative materials to bismuth telluride and be adopted by the thermoelectric power generation component 201.

[0078] When designing and manufacturing the thermoelectric power generation component 201, based on the temperature difference between the surface temperature of the evaporator 101 and the surface temperature of the condenser 102 of the refrigeration device, materials suitable for its thermoelectric conversion efficiency and operating temperature are selected. These materials each have unique thermoelectric properties and can generate electric potential energy under the action of temperature difference. By utilizing the unique thermoelectric properties of these materials, the refrigeration device is made more efficient in energy utilization.

[0079] In the above technical solution, determining the thermoelectric material used by the thermoelectric power generation component according to the actual temperature difference between the evaporator and the condenser of the refrigeration device can maximize the utilization of this temperature difference to generate electric potential energy, improve the energy conversion efficiency, and enhance the energy consumption performance of the refrigeration device under different temperature differences.

[0089] In the above technical solution, the temperature conduction component respectively obtains the surface temperatures of the evaporator and the condenser through the temperature sensing probe, and conducts them to the thermoelectric power generation component through the transmission wire arranged in the heat preservation sheath. The thermoelectric power generation component converts the temperature difference into electric potential energy through the thermoelectric effect, which is used to drive the cooling fan, can reduce the loss in the temperature conduction process, and improve the energy utilization rate.
