[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figures 1-5 A small semiconductor waterless single-stage refrigerator includes a flow channel turbulence outlet 1 and a flow channel main cavity 2, as shown in the attached instruction manual. Figure 1 The flow channel turbulence outlet 1 is installed inside the main flow channel cavity 2. The outer wall of the flow channel turbulence outlet 1 is provided with a threaded groove. The flow channel turbulence outlet 1 and the main flow channel cavity 2 are threadedly connected. The outer wall of the flow channel turbulence outlet 1 is provided with a rubber sealing ring. The rubber sealing ring is set in an O-shape. Through the mutual cooperation between the rubber sealing ring and the main flow channel cavity 2, a sealing effect is formed between the flow channel turbulence outlet 1 and the main flow channel cavity 2, reducing fluid leakage and ensuring the stability of the entire equipment during operation. It also facilitates the installation and disassembly of the flow channel turbulence outlet 1 by the operator.
[0023] The main cavity 2 of the flow channel is provided with a connecting bracket 3 on its side wall. The connecting bracket 3 is provided with a temperature conversion plate 6 on its side wall. The connecting bracket 3 and the main cavity 2 of the flow channel are slidably connected by a hook. The connecting bracket 3 is threadedly connected to the temperature conversion plate 6 by a bolt assembly. Through the cooperation of the connecting bracket 3 and the temperature conversion plate 6, the temperature conversion plate 6 is installed on the side wall of the main cavity 2 of the flow channel, which facilitates the operator to disassemble and maintain the temperature conversion plate 6 in the future, and ensures the efficiency of the operator in the maintenance of the equipment.
[0024] The temperature conversion plate 6 has heat dissipation fins 8 on its side wall and a thermoelectric cooler 7 inside the temperature conversion plate 6. The heat dissipation fins 8 are threadedly connected to the temperature conversion plate 6 by bolt assemblies. The temperature conversion plate 6 has a storage slot with a rectangular shape. The thermoelectric cooler 7 is fixedly installed on the inner side wall of the storage slot. The side wall of the heat dissipation fins 8 is connected to the side wall of the thermoelectric cooler 7. Through the cooperation between the thermoelectric cooler 7 and the heat dissipation fins 8, the thermoelectric cooler 7 can achieve cooling or heating effects after being powered on. The heat dissipation fins 8 dissipate the heat generated by the thermoelectric cooler 7, ensuring that the thermoelectric cooler 7 can work continuously and stably.
[0025] The heat dissipation fin 8 is provided with a power input port protection base 5 at its end. The power input port 4 is fixedly installed at the end of the power input port protection base 5. The power input port 4 is connected to the cooling fan 9 and the thermoelectric cooler 7 respectively. Through the cooperation of the power input port 4 and the power input port protection base 5, power is input to the cooling fan 9 and the thermoelectric cooler 7, ensuring the normal operation of the equipment. The power input port protection base 5 also protects the power input port 4, reducing the possibility of damage to the power input port 4 caused by external factors and extending the service life of the equipment.
[0026] It should be noted that when the thermoelectric cooler 7 is a single-sided structure, it is only used for cooling, which is the most common application. The single-sided thermoelectric cooler 7 generates cold or heat on one side.
[0027] In some embodiments, the semiconductor cooling chip 7 preferably has a double-sided structure, in which both sides generate both cooling and heating simultaneously, i.e., a cooling-heating type.
[0028] A cooling fan 9 is provided on the side wall of the heat dissipation fin 8, and a protective plate 10 is fixedly installed on the side wall of the cooling fan 9. The cooling fan 9 and the protective plate 10 are threadedly connected to the heat dissipation fin 8 by a screw assembly. Through the cooperation between the cooling fan 9 and the thermoelectric cooler 7, the cooling fan 9 dissipates heat from the thermoelectric cooler 7. When the thermoelectric cooler 7 is working, it generates heat. When the cooling fan 9 is started, it accelerates the airflow speed to dissipate the heat generated by the thermoelectric cooler 7 to the surrounding environment, reducing the impact of the thermoelectric cooler 7 on the operating efficiency of the equipment due to excessive temperature, and ensuring the stability and safety of the equipment power supply.
[0029] The functional principle of this utility model can be explained through the following operation methods:
[0030] When the equipment is started, the power is connected through the power input port 4, and the semiconductor cooling chip 7 starts to work. The semiconductor cooling chip 7 begins to generate cooling energy, which is conducted to the main cavity 2 of the flow channel through the temperature conversion plate 6, thereby reducing the internal temperature of the main cavity 2 and achieving a cooling effect. Combined with the turbulence balancing effect of the upper outlet 1 of the flow channel, the high-temperature material entering from the lower inlet of the main cavity 2 of the flow channel can be cooled evenly. The high-temperature material is smoothly discharged through the upper outlet 1 of the flow channel. The threaded groove and rubber sealing ring on the outer wall of the upper outlet 1 of the flow channel enhance the stability of the connection when the upper outlet 1 of the flow channel is threadedly connected to the main cavity 2 of the flow channel, effectively reducing liquid leakage in the flow channel and ensuring the sealing of the equipment operation. The connecting bracket 3 is slidably connected to the main cavity 2 of the flow channel by a hook and is threadedly connected to the temperature conversion plate 6 by a bolt assembly, ensuring the reliability of the connection.
[0031] The dual-chip combination of the semiconductor cooling chip 7 connects the positive and negative electrodes of the two chips in series. The operator can switch the positive and negative electrodes to interchange the hot and cold sides, so that the system can automatically switch to cooling mode when the temperature is too high and switch to heating mode when the temperature is too low, thus realizing the self-adjustment and control of temperature.
[0032] Refer to the instruction manual appendix Figure 1 With appendix Figure 4 In some implementations, when the thermoelectric cooler 7 adopts a double-sided structure, the double-sided thermoelectric cooler 7 generates both cooling and heating on both sides simultaneously. Operators can replace and disassemble it according to the application scenario. When a single cooling function is required, a single-sided thermoelectric cooler 7 with the cold side facing the main cavity 2 of the flow channel can be selected. When a heat exchange function is required, a double-sided thermoelectric cooler 7 is selected. The double-sided thermoelectric cooler 7 can generate different temperatures on both sides simultaneously. One side of the thermoelectric cooler 7 cools, while the other side delivers heat, allowing the thermoelectric cooler 7 to switch between hot and cold sides during operation. When it is overheated, the thermoelectric cooler 7 cools; when it is undercooled, the thermoelectric cooler 7 heats. This achieves self-controllable temperature, ensuring the working efficiency of the equipment in single cooling and heat exchange, realizing temperature control of different areas, reducing energy waste, and lowering the cost of use.
[0033] By activating the cooling fan 9, the heat on the heat sink 8 is dissipated, preventing the temperature of the heating end of the thermoelectric cooler 7 from becoming too high and ensuring its continuous and stable operation. The protective plate 10 protects the cooling fan 9 and reduces the risk of damage from impacts by external objects during operation.
[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
