Air cooling systems rely on air convection to remove heat, resulting in a relatively simple structure and low cost. However, their cooling effect is significantly affected by ambient temperature, especially in high-temperature environments where air cooling efficiency drops markedly, leading to unstable water temperature regulation. Furthermore, air cooling systems typically occupy a large space, limiting the compactness and design flexibility of the overall water purification equipment, making it difficult to meet the demands of modern water treatment equipment for miniaturization and high efficiency.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Existing water purification equipment generally uses air cooling, employing fans and heat sinks to cool or refrigerate the water tank. Air cooling systems rely on air convection to remove heat, resulting in a relatively simple structure and low cost. However, their cooling effect is significantly affected by ambient temperature, especially in high-temperature environments where air cooling efficiency drops markedly, leading to unstable water temperature regulation. Furthermore, air cooling systems typically occupy a large space, limiting the compactness and design flexibility of the overall water purification equipment, making it difficult to meet the demands of modern water treatment equipment for miniaturization and high efficiency.

[0031] Based on this, see Figures 1 to 2 As shown, this utility model embodiment provides a water treatment device 10, which includes a water storage tank 100 and a temperature control device 200; the water storage tank 100 is provided with a water storage area 110 and a subcooling area 120; the temperature control device 200 includes a cooling element 210, which is thermally coupled to the water storage tank 100, and the cooling element 210 is used to prepare subcooled water 20 in the subcooling area 120.

[0032] The water treatment equipment 10 of this embodiment, by setting a subcooling zone 120 within the water storage tank 100 and using a heat-conducting component 210 to prepare subcooled water 20 within this subcooling zone 120, can store more cooling capacity, achieving pre-accumulation of cooling resources and effectively improving the cooling effect of the water treatment equipment 10. Unlike traditional air-cooled systems that rely on air convection for heat dissipation, the heat-conducting component 210 in this embodiment is directly thermally coupled to the water storage tank 100, effectively improving cooling efficiency, reducing dependence on ambient temperature, and ensuring the stability of water temperature regulation. The subcooled water 20 prepared within the subcooling zone 120 has a lower temperature, enabling it to store more cooling capacity and achieve pre-accumulation of cooling resources. Specifically, the temperature range of the subcooled water 20 can be set from below 0℃ to near the freezing point, such as -2℃, -1℃, 0℃, etc., determined according to actual design requirements, and is not limited to a single value here.

[0033] Meanwhile, the subcooled water 20 prepared by the cooling conductor 210 can quickly release cold energy when needed, improving the cooling response speed and efficiency to meet rapid cooling requirements. It also makes efficient use of space, resulting in a more compact overall equipment structure and meeting miniaturization design requirements. Furthermore, the subcooled water 20 prepared by the cooling conductor 210 can quickly release cold energy when needed, improving the cooling response speed and efficiency, thus solving the problems of poor cooling effect, large space occupation, and unstable cooling in existing air-cooled systems.

[0034] In one embodiment, the subcooled zone 120 is at least partially located at the bottom of the water storage zone 110. This arrangement is based on the principles of gravity and thermodynamics, making full use of the natural settling characteristics of cold water when it has a higher density and lower temperature, so that the subcooled water 20 can be deposited in the bottom area of ​​the water storage tank 100, thereby achieving a temperature stratification effect inside the water tank.

[0035] Specifically, cold water has a higher density than warm water, so in the water tank, cold water naturally sinks to the bottom, while the warmer water remains on top, creating a significant temperature gradient. This temperature stratification not only helps to stably preserve the subcooled water 20, preventing it from mixing with the warmer water in the storage area 110 and thus avoiding heat loss, but also effectively maintains a stable heat gradient within the storage tank 100, improving the overall heat exchange efficiency and cooling effect of the tank.

[0036] Furthermore, placing the subcooled zone 120 at the bottom of the water tank 100 facilitates a compact layout of the refrigeration unit and saves space. The subcooled water 20 is concentrated in the bottom area, allowing the cooling conductor 210 to directly act on this area, improving refrigeration efficiency, reducing energy loss, and meeting the requirements of miniaturized equipment design.

[0037] In one embodiment, by providing a drain valve in the subcooled zone 120, the subcooled water 20 can be effectively discharged and controlled, facilitating operation during equipment maintenance, cleaning, or when the subcooled water needs to be released quickly, thereby improving the practicality and convenience of the equipment.

[0038] Specifically, the drain valve can be a pressure valve, such as a duckbill valve. Duckbill valves are simple in structure and low in cost, with automatic opening and closing functions. They can automatically adjust the discharge volume according to the internal water pressure, eliminating the need for a complex external control system, making them suitable for applications requiring a simple drainage process. The elastic material design of the duckbill valve allows it to remain closed under no or low pressure, effectively preventing water leakage from the tank or the entry of external impurities, thus ensuring the stability of the water quality within the subcooling zone of 120°C.

[0039] In addition, the drain valve can also be an electrically controlled valve, which can be remotely or automatically controlled through an electrical control system. It can precisely adjust the timing and volume of drainage based on the operating status of the water treatment equipment 10, temperature sensor feedback, or user needs. Electrically controlled valves have the advantages of fast response and precise control, and are suitable for water treatment equipment that requires highly automated management and rapid response, thereby improving the overall intelligence level of the equipment and the user experience.

[0040] The drain valve not only helps to periodically remove sediment or impurities from the subcooled zone 120, preventing any impact on the preparation and storage efficiency of the subcooled water 20, but it can also be used for emergency drainage to prevent excessive water volume in the subcooled zone from causing equipment malfunctions. Furthermore, a well-designed structure and location of the drain valve can prevent the drainage process from adversely affecting the water temperature stability of the storage zone 110, ensuring the overall stability and efficient cooling effect of the equipment. It should be noted that the number of drain valves can be one, two, or more, depending on specific design requirements; there is no single limitation. Installing multiple drain valves allows for zoned drainage, improving drainage efficiency and flexibility, and adapting to maintenance needs under different operating conditions.

[0041] In one embodiment, a partition 130 is provided inside the water tank 100, and a connection hole 131 is provided thereon, which connects the water storage area 110 and the subcooling area 120 respectively. The partition 130 has important technical significance and practical effect.

[0042] First, the separator 130 effectively prevents the water 30 in the water storage area 110 from directly disturbing the subcooled water 20 in the subcooled area 120. Since the temperature of the subcooled water 20 is lower than that of the ordinary water 30 in the water storage area 110, if the two mix violently or flow turbulently, the temperature of the subcooled water 20 can easily rise or even partially freeze, affecting the cooling stability and safety of the equipment. The separator 130, through physical separation, partially isolates the subcooled area 120 from the water storage area 110, reducing heat exchange disturbances between the water bodies, ensuring the stable existence of the subcooled water 20, reducing the risk of freezing, and improving the stability of temperature stratification within the entire water storage tank 100.

[0043] The design of the connection hole 131 enables limited flow between the water storage zone 110 and the subcooled zone 120, ensuring proper water circulation and temperature balance while avoiding temperature disturbances caused by vigorous mixing. The size, number, and distribution of the connection holes 131 can be adjusted according to actual needs; for example, the diameter of the connection holes can be 5mm, 8mm, 10mm, 12mm, etc., specifically optimized based on fluid dynamics and heat conduction requirements. Too small a diameter may cause water flow blockage, affecting circulation efficiency; too large a diameter may lead to excessive mixing of the subcooled water 20 and the water storage zone 110, compromising the subcooling effect. A well-designed connection hole 131 helps maintain temperature stratification of the water inside the storage tank, improving overall cooling efficiency and system stability.

[0044] Furthermore, the structure and material selection of the separator 130 also affect equipment performance. The separator 130 can be made of thermally insulating materials, such as food-grade plastics, to further reduce heat conduction and enhance the thermal stability of the subcooled zone 120. The separator 130 can also be made of metal with surface treatment to prevent corrosion, combined with a good sealing design to ensure long-term stable operation.

[0045] The cooling component 210 pre-stores cold energy by preparing a certain amount of subcooled water 20, and the separator 130 ensures the stable storage and utilization of this cold energy. Storing more subcooled water 20 means that the equipment can quickly release a large amount of cold energy when needed, meeting rapid cooling requirements and improving cooling response speed. At the same time, the stable presence of subcooled water 20 reduces the risk of icing, avoiding equipment failures and maintenance costs caused by icing, and ensuring the safe operation and service life of the equipment.

[0046] In one embodiment, the water treatment device 10 further includes a filter element assembly 300, the output end of which is connected to the inlet end 111 of the water storage tank 100. The filter element assembly 300 is used to install an external filter element, including an RO filter element. By setting up the filter element assembly 300, especially by using an RO filter element to pre-treat the water 30 flowing into the water storage tank 100, the purity of the water can be significantly improved, ensuring the stability of the subcooled water 20 in the subsequent subcooling zone 120 and the overall safety of the equipment operation.

[0047] As a highly efficient membrane separation technology device, the RO filter cartridge can effectively remove suspended particles, microorganisms, dissolved salts, and other impurities from water, producing high-purity water. Water 30 that enters the storage tank 100 after filtration by the RO filter cartridge has a significantly reduced impurity content, reducing the risk of contamination and clogging of the storage tank and cooling components 210 by solid particles and microorganisms. It also reduces the possibility of impurities forming ice nuclei at low temperatures.

[0048] Specifically, the filtered water 30 significantly reduces foreign matter and solutes that could cause freezing. This results in purer water 30 entering the storage tank 100, effectively preventing localized freezing of the supercooled water 20 due to impurities, reducing the risk of freezing inside the storage tank 100, and improving the equipment's cooling efficiency and operational stability.

[0049] The filter cartridge assembly 300 can be designed with one or more filter cartridge units according to actual needs. The specific number can be one, two, or more in series or parallel to meet the requirements of different treatment capacities and filtration precisions. The types of filter cartridges in the filter cartridge assembly 300 are not limited to RO filter cartridges, but may also include pre-filter cartridges, activated carbon filter cartridges, ultrafiltration membranes, and other multi-stage filtration devices to achieve multiple purification and protection of water body 30, thereby improving the applicability and treatment effect of the system.

[0050] In summary, by installing a filter element assembly 300 in the water treatment equipment 10 and using an RO filter element to filter the water 30 entering the storage tank 100, not only can impurities and dissolved salts in the water be effectively removed, preventing freezing, but the purity and stability of the subcooled water 20 can also be ensured, improving the cooling efficiency of the cooling component 210 and the overall operational safety of the equipment, thus meeting the technical requirements for efficient and stable operation of the water treatment equipment 10. Specifically, the water treatment equipment 10 can be a water purifier.

[0051] In one embodiment, the temperature control device 200 further includes a temperature sensor configured to measure the temperature of the subcooled water 20 in the subcooled zone 120. The temperature sensor can be of various types, such as a thermocouple, a thermistor (e.g., PT100), a semiconductor temperature sensor, or an infrared temperature sensing element. The specific selection can be determined based on factors such as measurement accuracy requirements, response speed, and overall equipment structural limitations. The temperature sensor is preferably located within the subcooled zone 120, in direct contact with or adjacent to the subcooled water 20, to ensure the accuracy and real-time nature of the measurement data.

[0052] The water treatment equipment 10 also includes a control module, to which the temperature sensor and the cooling conductor 210 are communicatively connected. By receiving real-time temperature data of the subcooled water 20 from the temperature sensor, the control module can accurately monitor the temperature changes of the subcooled water 20. Based on this temperature information, the control module implements intelligent control of the cooling conductor 210, including start / stop control, power adjustment, and cooling capacity distribution, thereby achieving feedback regulation of the subcooled water 20 temperature.

[0053] Specifically, when the temperature sensor detects that the temperature of the subcooled water 20 has dropped below a set threshold, the control module can reduce the cooling intensity of the cooling conductor 210 or stop cooling to prevent the risk of icing due to excessively low subcooled water 20 temperature. Conversely, when the temperature of the subcooled water 20 rises to a certain range, the control module activates or enhances the cooling capacity of the cooling conductor 210 to quickly lower the water temperature and maintain the stability of the subcooled state. Through this closed-loop feedback control system, precise regulation of the subcooled water 20 temperature can be achieved, avoiding excessive temperature fluctuations, thereby effectively preventing icing and improving equipment safety and operating efficiency.

[0054] In addition, the control module can preset multiple temperature thresholds according to different operating conditions and requirements, realizing multi-level adjustment and further optimizing the temperature control curve of the subcooled water 20. The measurement accuracy and response time of the temperature sensor have a significant impact on the control effect. It is preferred that the measurement error of the temperature sensor be controlled within ±0.1℃ and the response time be less than 1 second to ensure that the system can respond to temperature changes in a timely manner.

[0055] The control module can also integrate data logging and remote communication functions to monitor and record the temperature changes of the subcooled water 20 and the operating status of the cooling components 210 in real time, facilitating equipment maintenance and performance optimization. Simultaneously, the control module can be combined with other sensors (such as flow sensors and pressure sensors) to achieve multi-parameter coordinated control, further enhancing the intelligence level and operational stability of the water treatment equipment 10.

[0056] In a preferred embodiment, the number of temperature sensors can be multiple. Specifically, there can be one, two, three, or more sensors, and the specific number can be rationally arranged according to the structural dimensions of the subcooled zone 120 and the flow state of the water body 30. By setting multiple temperature sensors at different locations, multi-point temperature measurement of the subcooled water 20 can be achieved, thereby obtaining more comprehensive and accurate temperature distribution information, effectively avoiding measurement errors that may be caused by single-point temperature measurement and the problem of difficulty in detecting local temperature anomalies. Multi-point measurement not only improves the accuracy and reliability of temperature measurement, but also helps the control module to more accurately assess the overall temperature change trend of the water body 30 within the subcooled zone 120, thereby achieving more precise and dynamic water temperature feedback control and preventing the risk of freezing due to local supercooling.

[0057] The control module can employ various controller types, including but not limited to PLCs (Programmable Logic Controllers), STM32 microcontrollers (32-bit microcontrollers based on the ARM Cortex-M core), microcontrollers, FPGAs (Field Programmable Gate Arrays), and ARM processors (Advanced RISC Machines). These control modules can be integrated within the water treatment equipment 10 to receive real-time temperature data from temperature sensors, execute complex control algorithms, and directly control the operating status of the cooling conductor 210.

[0058] The advantages of using a PLC as the control module lie in its high stability, strong anti-interference capability, flexible programming, and ease of integration into industrial settings, making it suitable for demanding industrial applications. STM32 and ARM processors offer advantages such as high computing power, low power consumption, and abundant peripherals, making them suitable for intelligent control systems requiring complex data processing and remote communication. FPGAs are suitable for scenarios with highly customized control logic and high-speed response requirements. Microcontroller controllers are typically lower in cost and suitable for systems with simple structures and relatively basic control tasks.

[0059] By appropriately selecting and configuring control modules, various functions such as start / stop control, cooling power adjustment, fault diagnosis, and alarms for the cooling conductor 210 can be achieved, meeting the control requirements of different water treatment equipment 10. Simultaneously, the control module supports multiple communication interfaces, such as CAN, Modbus, and Ethernet, facilitating data interaction with a host computer system or remote monitoring platform to achieve remote monitoring and maintenance.

[0060] Furthermore, the temperature control device 200 also includes a heating element, the working end of which is thermally coupled to the subcooled zone 120. Specifically, the heating element can be of various types, such as an electric heater, a hot water circulation heating system, an infrared heater, or an electric heating film. By setting the heating element in the subcooled zone 120, the temperature of the subcooled water 20 can be rapidly adjusted, enabling it to respond quickly to high temperature fluctuations and maintain the temperature within the set range.

[0061] The heating element is connected to the control module to ensure real-time reception of subcooled water 20 temperature data from the temperature sensor. When the control module detects that the subcooled water 20 temperature exceeds a preset upper limit threshold, it can control the heating element to start the heating process, thereby reducing the temperature fluctuation of the water. Specifically, the heating element can achieve precise temperature control by adjusting the heating power and heating time to prevent equipment instability or increased risk of freezing due to excessively high water temperature.

[0062] This heating element not only allows for the heating and regulation of the subcooled water 20, but also integrates with data feedback from the temperature sensor to form a highly efficient closed-loop control system. When the temperature of the subcooled water 20 fluctuates, the system can quickly respond and adjust the operating state of the heating element to maintain a stable water temperature and avoid potential risks caused by excessively high temperatures.

[0063] Furthermore, the layout and installation method of the heating element can be optimized according to actual conditions. For example, the heating element can be set as detachable or fixed to facilitate maintenance and replacement. In terms of material selection for the heating element, corrosion-resistant and high-temperature-resistant materials are preferred to ensure that it maintains good performance and stability during long-term operation.

[0064] In one embodiment, the water tank 100 is further provided with an exhaust valve 140, which is connected to the water storage area 110. By providing the exhaust valve 140 in the water storage area 110, the gas accumulated in the water storage area 110 can be effectively discharged, thereby preventing the gas from entering the subcooled area 120 and coming into contact with the subcooled water 20, and avoiding the gas from forming bubbles or acting as ice nuclei in the subcooled water 20, which would cause the subcooled water 20 to freeze.

[0065] Specifically, the water storage zone 110, as the initial collection area for water, may contain dissolved gases or gases generated by the system operation. If these gases cannot be discharged in time, they will flow into the subcooling zone 120 with the water flow, causing localized bubbles or tiny ice nuclei to form in the subcooled water 20, reducing its stability and increasing the risk of freezing. The vent valve 140 enables automatic or manual venting of gases from the water storage zone 110, maintaining a low gas content in the water and ensuring that the water entering the subcooling zone 120 is purer and more uniform.

[0066] The air vent valve 140 can take various forms, including a mechanical automatic air vent valve, an electrically controlled air vent valve, or a float valve. Mechanical automatic air vent valves have a simple structure and can automatically open to release air when system pressure changes, resulting in low maintenance costs. Electrically controlled air vent valves are suitable for linkage with control modules to achieve automatic detection and control of the air venting process, improving the system's intelligence level. Float valves have a reliable structure, are suitable for various working environments, and can effectively prevent water leakage.

[0067] By rationally arranging and designing the parameters of the vent valve 140, the gas in the water storage area 110 can be released in a timely manner, effectively reducing the induced freezing effect of gas on the subcooled water 20 and ensuring the stability and purity of the subcooled water 20. At the same time, the vent valve 140 can also reduce pressure fluctuations caused by gas accumulation inside the water storage tank 100, improving the overall operational safety and reliability of the equipment.

[0068] Furthermore, the maintenance and repair of the air release valve 140 are relatively simple. The valve's sealing performance and opening sensitivity can be checked periodically to ensure its long-term stable operation. The air release valve should be made of corrosion-resistant and pressure-resistant materials, such as stainless steel, alloy steel, or high-performance engineering plastics, to meet the operating conditions and environmental requirements of the water treatment equipment 10.

[0069] In summary, the installation of an exhaust valve 140 in the water storage tank 100 and its connection to the water storage area 110 not only enables the effective discharge of gas from the water storage area 110 and prevents gas from entering the subcooled water 20 and causing freezing, but also improves the safety and cooling efficiency of the water treatment equipment 10. This is one of the important technical measures to ensure the stable operation of the equipment.

[0070] In one embodiment, the water storage tank 100 consists of a first water tank and a second water tank, wherein the water storage area 110 is disposed in the first water tank and the subcooling area 120 is disposed in the second water tank, and the first water tank and the second water tank are connected to each other. By arranging the water storage area 110 and the subcooling area 120 in two independent water tanks respectively, effective isolation between the two areas is achieved.

[0071] The technical principle behind this structural design lies in physically separating the ordinary water 30 in the storage area 110 from the supercooled water 20 in the supercooled area 120, thus avoiding direct mixing and heat exchange interference between the two in the same container. The water temperature in the storage area 110 is generally higher than that in the supercooled area 120. If both were placed in the same tank, vigorous flow and heat convection could easily occur between the water bodies, leading to temperature fluctuations in the supercooled water 20 and even an increased risk of freezing. By using two interconnected but structurally independent tanks, limited water exchange and heat transfer can be achieved through flow channels or valves at the interface, while simultaneously preventing excessive mixing of the water and ensuring stable temperature control within the supercooled area 120.

[0072] Specifically, the connection method between the first water tank and the second water tank may include, but is not limited to, pipe connection, flange interface or sealed connection structure, and the connection part is equipped with a valve or connection hole to regulate the flow rate and flow size of the water between the two water tanks.

[0073] By placing the water storage zone 110 and the subcooling zone 120 in separate water tanks, not only can the temperature stratification stability of the water be improved, but it also facilitates differentiated material selection and structural design for each tank. For example, the second water tank, where the subcooling zone 120 is located, can use excellent thermal insulation materials and an anti-icing layer to reduce heat loss and prevent freezing. The first water tank, on the other hand, can focus on corrosion resistance and structural strength to meet the needs of water storage and flow.

[0074] Furthermore, the independent design of the two water tanks facilitates equipment maintenance and repair. The first and second water tanks can be disassembled or replaced separately, allowing for specialized maintenance of key components such as the temperature control system of the subcooling zone 120, the cooling conductors, and the anti-icing layer, thereby improving the overall service life and operational reliability of the equipment.

[0075] In one embodiment, the water tank 100 is further provided with a flow-regulating element, which is disposed between the water inlet 111 of the water storage area 110 and / or between the subcooled area 120 and the water storage area 110. The flow-regulating element is mainly used to regulate the flow rate of the water 30, so as to achieve slow delivery and uniform distribution of the water 30 flowing into the water storage area 110 and the water 30 flowing from the water storage area 110 into the subcooled area 120, thereby effectively reducing turbulence and local temperature fluctuations caused by excessive flow rate, and preventing local freezing of the subcooled water 20 in the water body 30.

[0076] Specifically, flow-regulating components can take various forms, such as mesh filters, perforated plates, curved flow channels, throttling valves, honeycomb diversion structures, or perforated plates. The materials for these components can be corrosion-resistant, high-mechanical-strength metals (such as stainless steel or aluminum alloys) or food-grade plastics. The pore size, porosity, and flow channel shape of the flow-regulating components can all be designed and adjusted according to the actual flow rate and equipment structure to achieve optimal flow rate control.

[0077] The number and arrangement of the flow-slowing elements can be flexibly configured according to the volume of the water storage tank 100 and the water flow characteristics. The specific number can be one, two, or more, and they can be set individually at the water inlet 111 or simultaneously at the connection between the water storage area 110 and the subcooling area 120. Through multi-point flow-slowing arrangement, the water flow energy can be more effectively dispersed, avoiding localized overcooling or freezing of the subcooled water 20 caused by excessively fast local water flow velocity.

[0078] By incorporating flow-damping components, the flow velocity of the water 30 entering the water storage zone 110 is effectively reduced, increasing the residence time of the water in the water storage zone and the subcooling zone. This promotes a more uniform and stable water temperature distribution, reducing temperature gradients and turbulent flow within the water. The flow-damping components also reduce the kinetic energy of water impacting the walls of the water storage tank or the surface of the cooling components 210, lowering the likelihood of localized icing, protecting the equipment structure, and extending the equipment's service life.

[0079] In addition, the design of the flow-retarding component also serves to filter impurities, preventing larger particles from entering the subcooled zone 120, reducing the risk of impurities clogging the cooling conductor 210, and improving the overall reliability and ease of maintenance of the system. The installation location and structure of the flow-retarding component should facilitate disassembly and cleaning to ensure long-term stable operation of the equipment and avoid the risk of uneven flow and icing due to clogging.

[0080] In one embodiment, the water treatment device 10 further includes a housing structure 400 for serving as a mounting carrier for the water tank 100, the temperature control device 200, and the filter assembly 300.

[0081] Specifically, the shell structure 400 is used to fix and protect the water tank 100, the temperature control device 200, and the filter element assembly 300, ensuring a stable connection and reasonable spatial layout between the components, which is beneficial to the compactness of the overall equipment structure and the improvement of mechanical strength. The shell structure 400 can be made of corrosion-resistant and temperature-deformation-resistant materials, such as ABS plastic, stainless steel, aluminum alloy, or composite materials, depending on the application environment and cost requirements. In high-humidity or highly corrosive environments, using stainless steel or special composite materials as the material for the shell structure 400 can effectively extend the service life of the equipment and ensure structural safety.

[0082] By setting the shell structure 400 as the installation carrier, not only is the structural stability and durability of the water treatment equipment 10 improved, but also the rational integration of various functional modules is realized, promoting the miniaturization and aesthetics of the whole machine, and meeting the comprehensive requirements of modern water treatment equipment 10 for high efficiency, reliability and portability.

[0083] Specifically, the cooling component 210 includes at least one of a semiconductor cooling chip, a compressor cooling unit, and a cooling plate. These three components can be used individually or in combination to meet the cooling requirements and operating conditions of different water treatment equipment 10.

[0084] Semiconductor coolers, as a type of cooling element based on the Peltier effect, have advantages such as compact structure, fast response speed, no moving mechanical parts, and low noise. Semiconductor coolers can achieve precise temperature control through current regulation, making them suitable for rapid temperature adjustment and localized cooling of subcooled water 20. Specifically, semiconductor coolers can be placed at key locations in the subcooled zone 120, directly thermally coupled to the water body 30 or the heat-conducting medium, improving heat exchange efficiency.

[0085] As a traditional mechanical refrigeration device, the compressor chiller can provide a large cooling capacity and is suitable for temperature control of large volumes of water. The compressor chiller absorbs heat from the subcooled water 20 through refrigerant circulation, thus lowering the water temperature. Its advantages include high cooling efficiency, wide applicability, and stable operation. The compressor chiller can be installed outside or inside the water treatment equipment 10, transferring cooling capacity to the subcooled zone 120 via cooling coils or cooling plates.

[0086] As a heat transfer structural component, the cooling plate is typically made of a high thermal conductivity material, such as aluminum alloy or copper, and is installed at the bottom or sidewall of the subcooled zone 120. Through close thermal coupling with the cold end of the thermoelectric cooler or compressor, the cooling plate efficiently transfers the cooling energy generated by the cooling device to the subcooled water 20, achieving uniform cooling. The cooling plate effectively expands the cooling area, improves the efficiency of cooling energy transfer, and prevents localized excessively low temperatures that could lead to icing.

[0087] Furthermore, the combined use of the thermoelectric cooler, compressor, and cooling plate in the cooling conductor 210 leverages their respective advantages to achieve efficient, precise, and stable temperature control. For example, the thermoelectric cooler is suitable for fine adjustments and rapid response, the compressor provides continuous high-power cooling, and the cooling plate ensures uniform distribution and transfer of cold energy. The control module receives temperature data from the temperature sensor of the subcooled water 20 and intelligently coordinates the start-up, shutdown, and power adjustment of each refrigeration unit to achieve closed-loop control. This ensures that the temperature of the subcooled water 20 is maintained within the ideal range, avoiding the risk of icing and improving system safety and operating efficiency.

[0088] In summary, the cooling component 210 includes at least one or more of a semiconductor cooling chip, a compressor cooling unit, and a cooling plate. Through reasonable configuration and optimized arrangement, it can achieve efficient cooling of the subcooled water 20 in the subcooled zone 120, ensure the stability and uniformity of the water temperature, and meet the comprehensive requirements of the water treatment equipment 10 for intelligence, energy saving, and safety.

[0089] In one embodiment, the water treatment device 10 further includes an extrusion pump connected to the inlet 111 of the water storage area 110, used to drive external water 30 into the water storage area 110. The outlet 121 of the water storage tank 100 is connected to the subcooling zone 120. With this structural layout, the extrusion pump can continuously pump room temperature water into the water storage area 110, realizing dynamic regulation of the water in the water storage tank 100.

[0090] Specifically, the room-temperature water injected into the water tank 100 by the extrusion pump forms a water circulation system with the subcooled water 20 in the subcooling zone 120. By continuously injecting room-temperature water, the subcooled water 20 in the subcooling zone 120 can be extruded and output as chilled water for use by external systems or users. This design enables the water circulation system to stably output chilled water at the required temperature, meeting the cooling needs of practical applications.

[0091] Furthermore, the injected room temperature water and subcooled water 20 mix to a certain extent inside the water storage tank 100. This mixing helps to finely adjust the temperature of the subcooled water 20. By adjusting the flow rate of the extrusion pump and the injected water temperature, precise control of the temperature of the mixed water can be achieved, thereby improving the stability and controllability of the outlet water temperature.

[0092] By using the extrusion pump in conjunction with the water tank 100, not only is effective water circulation achieved, but the stagnation of subcooled water 20 in the subcooling zone 120 is also avoided, thereby reducing the risk of localized freezing. The dynamically flowing water can maintain a uniform temperature, reduce temperature gradients caused by slow water flow or dead zones, and improve the overall cooling efficiency and safety of the system.

[0093] Meanwhile, the extrusion pump can be driven in various ways, such as using a motor-driven centrifugal pump, positive displacement pump, or screw pump, with the optimal type selected based on the specific flow and pressure requirements of the system. Motor-driven centrifugal pumps are often preferred due to their simple structure and ease of maintenance; positive displacement pumps are suitable for applications requiring stable flow output; and screw pumps perform well in high-viscosity or impurity-containing water. Furthermore, the extrusion pump can be linked with a control module to intelligently adjust the pump speed by real-time monitoring of temperature and flow data in the water tank 100 and subcooling zone 120, achieving automated control and further improving the system's intelligence and operational efficiency.
