[0002] In the traditional refrigeration field, compression refrigeration systems dominate. Currently, the ice maker and cold chain equipment industries generally face the following technical challenges:
[0003] Conventional compressor refrigeration systems have significant thermal inertia during startup, resulting in a long time required for the water temperature to drop from room temperature to freezing point. Evaporator precooling methods suffer from low heat exchange efficiency and high energy consumption. They rely on chemical refrigerants such as Freon and require phase change heat absorption to achieve cooling, but the compression process consumes significant energy.
[0004] Therefore, improvements are needed. Utility Model Content

[0023] This utility model discloses a pre-cooling device, mainly composed of an ice maker 1, a water-cooled plate 2, and a pre-cooling device 4. The ice maker 1 is equipped with a water inlet pipe 3 for introducing water to be cooled. The water-cooled plate 2 has continuously curved pipes 3 connected to the water inlet pipe 3, allowing water entering the ice maker 1 to flow through these pipes. The pre-cooling device 4 generates cooling energy and cools the water-cooled plate 2, thereby lowering the temperature of the water flowing through the pipes 3.
[0024] Ice maker 1 adopts the structure of commonly available ice-making equipment, and the diameter and material of its water inlet pipe 3 are selected according to actual needs. Ice maker 1 retains traditional ice-making systems, such as compressors, condensers, expansion valves, evaporators, and other components.
[0025] The water-cooled plate 2 is made of a metal material with good thermal conductivity, such as aluminum alloy. Aluminum alloy has the advantages of being lightweight and having a high thermal conductivity, which can quickly transfer the cooling energy generated by the semiconductor cooling chip to the water flowing through the pipe 3. The pipe 3 inside the water-cooled plate 2 is designed with continuous bends to increase the contact area between the water and the water-cooled plate 2 and improve the heat exchange efficiency. The specific bend shape can be optimized according to the size and shape of the water-cooled plate 2, for example, by using a spiral bend or a serpentine bend.
[0026] As an feasible technical solution, a pre-cooling device 4 is provided on the first end face of the water-cooled plate 2. The pre-cooling device 4 includes a first semiconductor cooling chip 5, a first heat-dissipating aluminum material 6, and a first cooling fan 7.
[0027] The number of first semiconductor cooling chips 5 is determined according to the cooling requirements and the size of the water-cooled plate 2, and in this embodiment, two chips are used. The two first semiconductor cooling chips 5 are arranged adjacent to each other on the first end face of the water-cooled plate 2, with their cold surfaces in close contact with the first end face of the water-cooled plate 2 to ensure efficient transfer of cooling energy to the water-cooled plate 2. The first semiconductor cooling chips 5 are selected from commercially available products with stable performance and high cooling efficiency, and their cooling power can be selected according to actual needs.
[0028] The first heat-dissipating aluminum material 6 is in contact with the hot surfaces of the two first semiconductor cooling chips 5, and is used to conduct away the heat generated by the semiconductor cooling chips. The first heat-dissipating aluminum material 6 adopts a finned structure to increase the heat dissipation area and improve heat dissipation efficiency. The spacing of the fins can be designed according to the heat dissipation requirements.
[0029] The first cooling fan 7 is mounted on the first heat-dissipating aluminum material 6 to accelerate airflow and dissipate heat from the aluminum material 6 into the surrounding environment. The model of the first cooling fan 7 is selected according to the heat dissipation requirements, and its airflow and air pressure must meet the heat dissipation requirements.
[0030] In a preferred embodiment, the present invention includes a first bracket 8, the first bracket 8 including a first plate 9 and a first leg 10 connected to the first plate 9, the first leg 10 being connected to the first end face of the water-cooled plate 2, the first plate 9 having an opening corresponding to the position of the first cooling fan 7, and the lower end face of the first plate 9 pressing the first heat-dissipating aluminum material 6.
[0031] The first support 8 includes a first plate 9 and a first leg 10. The first leg 10 is bolted to the first end face of the water-cooled plate 2 to ensure the stability of the first support 8. The first plate 9 has openings corresponding to the position of the first cooling fan 7 to ensure normal ventilation and heat dissipation of the first cooling fan 7. The lower end face of the first plate 9 presses against the first heat dissipation aluminum material 6, so that the first heat dissipation aluminum material 6 is in close contact with the hot surface of the first semiconductor cooling chip 5, thereby improving heat conduction efficiency.
[0032] The specific operating process is as follows: When the device starts working, the first semiconductor cooling chip 5 of the pre-cooling device 4 begins to operate, generating cooling energy using the Peltier effect of the semiconductor. This cooling energy is transferred to the water-cooled plate 2 through the cold surface. The water-cooled plate 2 then transfers the cooling energy to the water flowing through the pipe 3, lowering the water temperature. The heat generated by the first semiconductor cooling chip 5 is transferred to the first heat dissipation aluminum material 6 through the hot surface. The first cooling fan 7 accelerates airflow, dissipating the heat into the surrounding environment and ensuring the semiconductor cooling chip can operate continuously and stably. The water cooled by the water-cooled plate 2 then enters the ice maker 1 for ice making.
[0033] The above technical solution shortens the cooling time and improves the cooling efficiency: The pre-cooling device 4 of this utility model adopts a semiconductor cooling chip, which can start up quickly and generate cooling capacity, which directly acts on the water cooling plate 2, thereby quickly reducing the temperature of the water in the inlet pipe 3. This effectively overcomes the thermal inertia problem when the traditional refrigeration system starts up, greatly shortens the time required for the water temperature to drop to the freezing point, and improves the overall cooling efficiency.
[0034] Extending compressor life: Traditional ice makers rely on chemical refrigerants such as Freon, achieving cooling through phase change heat absorption, but the compression process consumes significant energy. This invention uses semiconductor refrigeration technology, eliminating the need for compression and directly utilizing the Peltier effect of semiconductors to achieve cooling, reducing the high energy consumption associated with compression and lowering overall energy consumption.

[0036] As a preferred technical solution, if further improvement in cooling efficiency is required, a second semiconductor cooling chip 11 can be provided on the second end face of the water-cooled plate 2. The number of second semiconductor cooling chips 11 can also be one or more, and in this embodiment, two can also be used. The two second semiconductor cooling chips 11 are arranged adjacent to each other, with their cold surfaces in contact with the second end face of the water-cooled plate 2 and their hot surfaces in contact with the second heat dissipation aluminum material 12.
[0037] The second heat dissipation aluminum material 12 has the same structure and material as the first heat dissipation aluminum material 6, adopting a finned structure and being tightly connected to the hot surface of the second thermoelectric cooler 11 for heat conduction. The second cooling fan 13 is mounted on the second heat dissipation aluminum material 12, and its model and performance requirements are consistent with the first cooling fan 7, used to accelerate the heat dissipation of the second heat dissipation aluminum material 12.
