Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquid cooling equipment technology, and in particular to a cold-tank refrigeration system. Background Technology
[0002] Existing tank-type refrigeration equipment typically uses water pumps or gravity flow for water supply and discharge. Water pump systems require additional components such as pumps and level sensors, leading to complex system structures, increased costs, and more potential points of failure. Gravity-based discharge systems impose strict limitations on installation layout, requiring the cooling tanks to be placed at a high position, severely restricting product design flexibility and making them unsuitable for all models.
[0003] Furthermore, traditional tankless water systems often rely on manual operation for initial water replenishment or refilling after evacuation. Users must manually activate the water replenishment function and observe whether water flows from the outlet to determine if replenishment is complete. This method is cumbersome, provides a poor user experience, and requires skilled operators. In the event of an unexpected power outage and subsequent restoration of power, the system may remain in a state of waiting for manual water replenishment and may not automatically resume normal operation.
[0004] Therefore, there are still shortcomings and deficiencies in the existing technology. How to provide a new type of cold tank refrigeration system with simple structure, flexible layout and fully automatic water replenishment and water outlet control is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0027] This utility model provides a cold-tank refrigeration system that achieves fully automatic exhaust and water replenishment through a control device. It has a high degree of automation and adopts a pressure-type water outlet method. It has no special requirements for the installation position of the cold-tank container 6 and can be easily adapted to various models.
[0028] Please refer to Figure 1 The refrigeration system with a cold tank provided by this utility model includes:
[0029] The cold container 6 is used to store liquids to be cooled, and a refrigeration unit is installed inside the cold container 6;
[0030] The liquid inlet pipe 8 is connected to the top of the cold container 6 and is used to supply liquid to the cold container 6. The liquid inlet pipe 8 is equipped with a water inlet valve 9.
[0031] The liquid outlet pipe 7 is connected to the bottom of the cold tank container 6 and is used to output the cooled liquid. The liquid outlet pipe 7 is equipped with a water outlet valve 10.
[0032] The exhaust pipe 13 is connected to the top of the cold container 6 and is used to exhaust the gas inside the cold container 6. The exhaust pipe 13 is equipped with an exhaust valve 12 and a water flow switch 16.
[0033] The control device is electrically connected to the inlet valve 9, the outlet valve 10, the vent valve 12, and the flow switch 16.
[0034] The cold-tank refrigeration system can be used to cool water or other liquids. The following explanation uses water as an example. When the cold-tank container 6 is initially filled with water or refilled after being emptied, the inlet pipe 8 is connected to the municipal water supply or other water source. The control device opens the inlet valve 9, outlet valve 10, and vent valve 12. Water is injected into the cold-tank container 6 through the inlet pipe 8. The air inside the cold-tank container 6 is compressed and expelled through the vent port of the vent pipe 13. As the water level in the cold-tank container 6 rises, when water overflows from the vent port of the vent pipe 13 after the cold-tank container 6 is full, the water flow switch 16 detects the water flow signal and sends a signal back to the control device. At this time, the control device closes the inlet valve 9, outlet valve 10, and vent valve 12, completing the water replenishment of the cold-tank container 6. This setup achieves fully automatic venting and water replenishment of the cold-tank container 6 without any manual operation, demonstrating a high degree of automation.
[0035] When a user needs to draw water, the control device closes the exhaust valve 12, then opens the inlet valve 9 and outlet valve 10. The continuous inlet pressure forces water into the cold tank container 6, causing the internal water level to rise and the pressure to increase. This forces the chilled water at the bottom of the cold tank container 6, cooled by the refrigeration unit, out through the outlet pipe 7, thus discharging water. To stop drawing water, simply close the inlet valve 9 and outlet valve 10. Because of the pressure-based water discharging method, the system does not rely on gravity and has no special requirements for the installation location of the cold tank container 6, greatly improving the flexibility of product design and allowing easy adaptation to various models.
[0036] Furthermore, with one end of the liquid inlet pipe 8 extending to the top of the cold tank container 6 and one end of the liquid outlet pipe 7 extending to the bottom of the cold tank container 6, the water in the cold tank container 6 enters from the top and exits from the bottom. Since cold water has a high density, the cold water cooled by the refrigeration unit will sink to the bottom of the cold tank container 6. By adopting the top-in, bottom-out method, the cold water discharged through the liquid outlet pipe 7 has a lower temperature and a larger single water intake, which significantly improves the user experience.
[0037] In some embodiments, the refrigeration unit includes an evaporator 15, the refrigerant pipe of the evaporator 15 is arranged in a spiral shape, and the evaporator 15 is disposed in the cold tank container 6 from top to bottom.
[0038] Please refer to Figure 1 The evaporator 15 is installed from top to bottom inside the cold container 6. The refrigerant pipes of the evaporator 15 are arranged in a spiral shape. The evaporator 15 utilizes the rapid vaporization of the refrigerant under low pressure to absorb heat, exchanging heat with the water in the cold container 6 to lower the water temperature and achieve a cooling effect. The spiral arrangement of the refrigerant pipes in the evaporator 15 increases the heat exchange area, thereby enabling faster and more efficient transfer of heat from the water to the refrigerant, achieving high-efficiency cooling.
[0039] In some embodiments, the inlet end of the refrigerant pipe is located at the upper part of the refrigerant pipe, and the outlet end of the refrigerant pipe is located at the lower part of the refrigerant pipe.
[0040] Please refer to Figure 1 When the evaporator 15 is working, the refrigerant enters from the upper inlet end and flows out from the lower outlet end. The refrigerant in the evaporator 15 exchanges heat with the water in the cold tank container 6 to cool the water. The water with lower temperature sinks to the bottom of the cold tank container 6, while the water with higher temperature is at the top of the cold tank container 6.
[0041] By placing the inlet and outlet of the refrigerant pipe at the top and bottom respectively, the refrigerant will preferentially exchange heat with the water at the top of the cold tank 6, which has a higher temperature. This fully utilizes the cooling capacity, improves heat exchange efficiency, and avoids the problem of localized overcooling and icing in the cold tank 6.
[0042] In some embodiments, a refrigerant delivery device is also included, which is connected to the inlet and outlet ends of the refrigerant pipeline of the evaporator 15 via pipelines.
[0043] In some embodiments, the refrigerant delivery device is compressor 1.
[0044] Please refer to Figure 1 In this embodiment, the refrigerant is a gaseous refrigerant. The compressor 1 is located outside the cold tank container 6. The main function of the compressor 1 is to achieve pressure increase, heat transfer and fluid drive in the refrigeration cycle by compressing and transporting the gaseous refrigerant.
[0045] In some embodiments, a radiator 2, a dryer filter 4, and a throttling device 5 are sequentially provided on the pipeline between the inlet end of the refrigerant pipeline of the compressor 1 and the evaporator 15.
[0046] Please refer to Figure 1 The radiator 2, the dryer filter 4, and the throttling device 5 are arranged sequentially on the pipeline from the side closer to the compressor 1 to the side farther away from the compressor 1. The radiator 2 mainly removes heat from the system; the dryer filter 4 absorbs moisture in the refrigeration system and filters impurities to prevent ice blockage and dirt blockage, thus protecting the normal operation of the refrigeration system; the throttling device 5 reduces the pressure and temperature of the refrigerant and controls its flow rate, thereby creating a low-temperature and low-pressure environment for the evaporator 15 to achieve effective refrigeration.
[0047] During operation, compressor 1 compresses and delivers gaseous refrigerant, which then passes through radiator 2 for heat dissipation, and dryer filter 4 for drying and filtration. It is then delivered to evaporator 15 through throttling device 5. After exchanging heat with water in cold tank container 6, the refrigerant flows back to compressor 1 for the next cycle.
[0048] In some embodiments, a cooling fan 3 is provided on one side of the radiator 2.
[0049] Please refer to Figure 1 The cooling fan 3 is located on one side of the radiator 2. The cooling fan 3 generates forced airflow through the rotation of its internal blades, which accelerates the heat dissipation from the surface of the radiator 2, thereby maintaining the normal operating temperature of the refrigerant.
[0050] In some embodiments, the inlet valve 9, the outlet valve 10, and the vent valve 12 are all solenoid valves. Solenoid valves have a fast response speed and can achieve precise control.
[0051] In some embodiments, the liquid outlet pipe 7 is also provided with a sterilizer 11.
[0052] Please refer to Figure 1 The sterilizer 11 is installed on the liquid outlet pipe 7. By installing the sterilizer 11, the water discharged through the liquid outlet pipe 7 can be sterilized, providing a safety guarantee for the user's drinking water. In this embodiment, the sterilizer 11 can specifically be a UV sterilizer 11 (i.e., an ultraviolet sterilizer 11), which can effectively kill bacteria colonies in the water flowing through the pipe.
[0053] In some embodiments, a placement tube 14 is fixedly provided inside the cold container 6, and a temperature sensor is installed on the placement tube 14.
[0054] Please refer to Figure 1 The placement tube 14 is fixed inside the cold tank container 6. The placement tube 14 provides a mounting base for the temperature sensor. The control device is electrically connected to the temperature sensor. By setting the temperature sensor, the water temperature inside the cold tank container 6 can be monitored in real time to ensure the cooling effect.
[0055] In this embodiment, the temperature sensor can be an NTC temperature sensor. NTC (Negative Temperature Coefficient) thermistors have a resistance value that decreases as the temperature increases and are widely used in the field of temperature detection and control.
[0056] The cold-tank refrigeration system provided by this utility model can automatically detect whether water replenishment is complete through the water flow switch 16 on the exhaust pipe 13, achieving fully automatic exhaust and water replenishment without manual intervention, with a high degree of automation. It adopts a pressure-type water discharge method, so the system operation does not rely on gravity and has no special requirements for the installation position of the cold-tank container 6, greatly improving the flexibility of product design and easily adapting to various models. Moreover, the cold water discharged through the liquid outlet pipe 7 has a lower temperature, significantly improving the user experience.
[0057] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.
[0058] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
