[0001] This utility model relates to the field of refrigeration technology, and in particular to a rapid cooling water device. Background Technology

[0002] With the continuous improvement of people's living standards, water dispensers have become a common sight in people's lives, and the variety of drinking water available is also increasing to meet different needs. For example, on hot days, people need to drink water at a lower temperature, hence the emergence of chilled water dispensers. However, existing chilled water tanks typically use refrigerant flowing through refrigeration pipes coiled inside the tank to transfer low temperatures to the water. This method suffers from poor cooling effect and long cooling time, failing to meet users' needs for rapid cooling. Furthermore, the existing refrigeration pipe structure design is not optimal, resulting in low heat exchange efficiency between the refrigerant and the water flow, further affecting the cooling effect. Therefore, existing technology urgently needs improvement to address these issues. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a rapid cooling water device to solve the problems of poor cooling effect and long cooling time of existing cooling water machines.

[0004] This utility model is achieved using the following technical solution:

[0005] The system includes a refrigeration pipe, a water storage tank, a refrigeration system, and a water supply system. The refrigeration pipe comprises an inner pipe and an outer pipe, with the outer pipe sleeved outside the inner pipe. A gap exists between the outer circumferential wall of the inner pipe and the inner circumferential wall of the outer pipe for refrigerant to pass through. The refrigeration pipe is spirally coiled around the outer circumferential wall of the water storage tank. The water flow direction inside the inner pipe is opposite to the refrigerant flow direction within the gap. The length of the inner pipe extends beyond the openings at both ends of the outer pipe. The openings of the inner and outer pipes are welded and sealed. The inner pipe has an inlet and an outlet, and the outer pipe has a refrigerant inlet and a refrigerant outlet. The water storage tank has an inlet and an outlet. The inlet of the inner pipe is connected to the water supply system, and the outlet of the inner pipe is connected to the inlet. The refrigerant inlet of the outer pipe is connected to the refrigerant outlet of the refrigeration system, and the refrigerant outlet of the outer pipe is connected to the refrigerant return port of the refrigeration system.

[0006] Furthermore, the outer tube is flat, and the inner diameter of the outer tube is larger than the outer diameter of the inner tube. The flat outer tube fits tightly against the outer peripheral wall of the water storage device.

[0007] Furthermore, the refrigeration pipe has multiple pipe rings coiled around the outer peripheral wall of the water storage device, and the pipe rings are tightly fitted together.

[0008] Furthermore, the water supply system includes a water pump motor, one end of which is connected to the water inlet of the inner pipe, and the other end of which is connected to a water source.

[0009] Furthermore, the outer tube is made of copper.

[0010] Furthermore, the inner tube is made of stainless steel.

[0011] Furthermore, the water storage device is made of stainless steel.

[0012] Furthermore, the refrigeration system includes a compressor, a condenser, a filter, and a capillary tube connected in sequence, with the refrigerant inlet of the outer tube connected to the outlet of the capillary tube.

[0013] Furthermore, the capillary is spiral-shaped.

[0014] Furthermore, it also includes a temperature sensor and a controller, wherein the probe of the temperature sensor extends into the water storage tank, and the controller is electrically connected to the temperature sensor and the compressor respectively.

[0015] Compared with the prior art, the beneficial effects of this utility model include at least the following:

[0016] In this invention, the refrigerant enters the gap between the outer and inner pipes through the refrigerant inlet of the outer pipe. The refrigerant releases its cooling energy to the water in the inner pipe and the outer wall of the water reservoir. After heat exchange with the water in the inner pipe and the outer wall of the water reservoir, the refrigerant flows back to the refrigeration system from the refrigerant outlet of the outer pipe. The water in the inner pipe, after being cooled, enters the cavity of the water reservoir through the water inlet. The cold water entering the water reservoir contacts the inner wall of the water reservoir to achieve a secondary cooling effect, realizing rapid cooling and cold retention. By utilizing the refrigerant in the gap to cool the water flowing through the inner pipe and the outer wall of the water reservoir—that is, through the dual cooling effect of counter-current cooling in the inner pipe and contact cooling in the water reservoir—rapid cooling is achieved, reducing cooling time and enabling immediate cold water output. The refrigeration pipe is spirally coiled around the outer wall of the water storage tank, which can effectively increase the contact area between the outer pipe and the water storage tank, improve refrigeration efficiency, and extend the heat exchange path, thus effectively improving refrigeration efficiency and refrigeration effect. Therefore, using this spiral refrigeration pipe to refrigerate water can achieve an instant cooling effect, realize the water rapid cooling function, eliminate the need to continuously maintain the low temperature of cold water, and reduce energy consumption. Furthermore, by coordinating the refrigeration pipe with the refrigeration system and the water supply system, refrigeration can be carried out on demand, further saving energy.

[0021] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0022] The terms used to describe position and direction in this utility model are illustrated with the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this utility model.

[0023] like Figure 1-3 As shown, this utility model provides a rapid cooling device, including a cooling pipe 1, a water storage tank 2, a cooling system, and a water supply system. The cooling pipe 1 includes an inner pipe 11 and an outer pipe 12. The outer pipe 12 is sleeved outside the inner pipe 11, and there is a gap 13 between the outer peripheral wall of the inner pipe 11 and the inner peripheral wall of the outer pipe 12 for refrigerant to pass through. The cooling pipe 1 is spirally coiled around the outer peripheral wall of the water storage tank 2. The water flow direction in the inner pipe 11 is opposite to the refrigerant flow direction in the gap 13. The length of the inner pipe 11 extends beyond the openings at both ends of the outer pipe 12. The pipe openings of the inner pipe 11 and the outer pipe 12 are welded and sealed. The inner pipe 11 has a water inlet 110 and a water outlet 111. The outer pipe 12 has a refrigerant inlet 120 and a refrigerant outlet 121. The water storage tank 2 has a water inlet interface 20 and a water outlet interface 21. The water inlet 110 of the inner pipe 11 is connected to the water supply system. The water outlet 111 of the inner pipe 11 is connected to the water inlet interface 20. The refrigerant inlet 120 of the outer pipe 12 is connected to the refrigerant outlet of the refrigeration system. The refrigerant outlet 121 of the outer pipe 12 is connected to the refrigerant return port of the refrigeration system.

[0024] In this embodiment, the outlet 111 of the inner pipe 11 is connected to the inlet 20, so that the inner pipe 11 is in communication with the inside of the water storage tank 2. The water supplied by the water supply system enters the inner pipe 11 through the inlet 110 and flows along the inner pipe 11, finally flowing into the inside of the water storage tank 2 through the inlet 20. The refrigerant from the refrigerant outlet of the refrigeration system enters the gap 13 between the outer pipe 12 and the inner pipe 11 through the refrigerant inlet 120 of the outer pipe 12, and flows along the gap 13 between the outer pipe 12 and the inner pipe 11 to the refrigerant outlet 121 and flows back to the refrigeration system.

[0025] In specific implementation, taking the heat exchange between water and low-temperature refrigerant as an example, the low-temperature refrigerant can enter the gap 13 between the outer pipe 12 and the inner pipe 11 through the refrigerant inlet 120 of the outer pipe 12. The low-temperature refrigerant can release cold energy to the water in the inner pipe 11 and the outer wall of the water storage tank 2. After heat exchange with the water in the inner pipe 11 and the outer wall of the water storage tank 2, the low-temperature refrigerant flows back to the refrigeration system from the refrigerant outlet 121 of the outer pipe 12. After being cooled, the water in the inner pipe 11 enters the cavity of the water storage tank 2 through the water inlet 20. The cold water entering the water storage tank 2 contacts the inner wall of the water storage tank 2 for cooling, achieving a secondary cooling effect, thereby achieving rapid cooling and cold preservation. In other words, the refrigerant in the gap 13 is used to cool the water flowing through the inner pipe 11 and the outer wall of the water storage tank 2. That is, this utility model achieves rapid cooling effect, reduces cooling time, and achieves immediate cold water output through the dual cooling effect of counter-current cooling of the inner pipe 11 and contact cooling of the water storage tank 2.

[0026] In this embodiment, the cooling pipe 1 is spirally coiled around the outer peripheral wall of the water storage tank 2, which can effectively increase the contact area between the outer pipe 12 and the water storage tank 2, improve the cooling efficiency, and extend the heat exchange path, thereby effectively improving the cooling efficiency and cooling effect. Thus, by using this spiral cooling pipe 1 to cool the water, the water can achieve an instant cooling effect, realizing the rapid cooling function of the water without continuously maintaining the low temperature of the cold water, which can reduce energy consumption. Furthermore, by cooperating with the cooling system and the water supply system, the cooling can be performed on demand, further saving energy.

[0027] Traditional refrigeration relies solely on a single-layer pipe wall for heat conduction, with the medium flowing in the same direction, resulting in low heat exchange efficiency. This invention places the refrigeration pipe 1 externally within the water storage tank 2, extending the heat exchange path through a double-layer counter-flow channel. This ensures the water flow remains in constant contact with the low-temperature refrigerant region, maintaining maximum temperature difference, effectively improving refrigeration efficiency and shortening cooling time. The counter-flow design maximizes heat conduction driven by temperature difference, and the dual cooling path accelerates heat dissipation. The external coiled form avoids the space limitations of traditional internal pipes, expanding the heat exchange area while maintaining a compact design. Water and refrigerant flow in opposite directions within independent channels, preventing medium mixing and contamination, and ensuring drinking water safety.

[0028] In a preferred embodiment, the outer tube 12 is flat, and its inner diameter is larger than that of the inner tube 11. The flat outer tube 12 fits tightly against the outer peripheral wall of the water reservoir 2. By designing the outer tube 12 as a flat structure, the contact area with the outer peripheral wall of the water reservoir 2 can be significantly increased compared to a traditional circular tube, resulting in a tighter physical fit. The flat cross-section structure minimizes the gap 13 between the tube wall and the surface of the water reservoir 2, effectively reducing the medium resistance during heat conduction. This flat design also makes the refrigerant flow path within the gap 13 closer to the wall of the water reservoir 2. Through the dual effects of increasing the heat exchange surface area and shortening the heat conduction distance, the heat exchange efficiency between the refrigerant and the water reservoir 2 is significantly improved. The flat outer tube 12 is easier to form a tightly arranged structure when coiled, avoiding the gap 13 generated when coiling a traditional circular tube, further optimizing the overall heat exchange performance.

[0029] In a preferred embodiment, the refrigeration pipe 1 is coiled around the outer peripheral wall of the water storage tank 2 with multiple pipe rings, and the pipe rings are tightly fitted together.

[0030] In this embodiment, multiple tube rings refer to the outer tube 12 forming a spiral winding structure with at least two turns on the outer wall of the water reservoir 2. Specifically, this can be achieved by using a continuous bending process to wind the outer tube 12 onto the outer surface of the water reservoir 2 at equal or variable intervals. This structure increases the path length of the refrigerant flow and expands the coverage area. The tight fit between tube rings means that there is no gap 13 between adjacent tube rings. This can be achieved by controlling the clamping force of the winding process to form a planar contact state for the outer tube 12 during winding. This structure eliminates the air layer between adjacent tube rings to reduce thermal resistance.

[0031] Specifically, the outer tube 12 forms a continuous heat conduction surface through a multi-layered coiling method. Each layer of the coil is in direct contact with the outer wall of the water tank 2, and heat is diffused laterally between adjacent coils through intermetallic conduction. The cold energy released by the refrigerant flowing through the outer tube 12 is transferred to the water tank 2 through the tube wall. The multi-layered coiling structure creates a composite circumferential and axial transfer path for the cold energy on the outer wall of the water tank 2, and the tight fit avoids heat loss caused by gaps 13 in traditional coil structures. Compared with existing technologies, traditional cold water tanks use a single-layer spiral coil structure with a large gap between the coils, which can only achieve heat exchange in a linear direction. In contrast, this embodiment forms surface contact heat conduction through multi-layered tight coiling, increasing the heat exchange area to several times that of traditional structures within the same water tank 2 volume, while eliminating the thermal resistance caused by the air insulation layer.

[0032] Through the above technical solution, this embodiment effectively increases the contact area between the refrigerant and the water tank 2, significantly improving the efficiency of cold energy transfer. Under the same refrigerant flow conditions, it shortens the time required for the water temperature in the cold water tank to drop, solving the problem of slow cooling speed caused by insufficient heat dissipation area in traditional devices.

[0033] In a preferred embodiment, the water supply system includes a water pump motor 7, one end of which is connected to the water inlet 110 of the inner pipe 11, and the other end of which is connected to the water source 8.

[0034] In this embodiment, the water pump motor 7 is a power device used to increase the water flow pressure, providing stable power to the water flow through mechanical drive. Its function is to overcome the problem of insufficient output pressure from the water supply equipment under natural flow conditions, ensuring continuous high-speed water flow within the inner pipe 11. The introduction of the water pump motor 7 changes the traditional passive circulation method that relies on natural water pressure or gravity, actively pressurizing and driving the water flow in the opposite direction to the refrigerant, forming forced convection heat exchange conditions. Specifically, the water pump motor 7 is installed between the water supply source 8 and the inlet 110 of the inner pipe 11. Under high pressure, the water flows through the inner pipe 11 at a higher velocity, exchanging heat with the refrigerant flowing in the opposite direction between the double-walled pipes. The pressurized water flow velocity is significantly higher than in the natural flow state, increasing the convective heat transfer coefficient between the water and the refrigerant, and accelerating the heat transfer rate. Simultaneously, the water pump motor 7 continuously outputs stable pressure, preventing water flow stagnation or backflow caused by pressure fluctuations in the water supply equipment, maintaining uninterrupted heat exchange.

[0035] This embodiment solves the problem of low water flow velocity caused by insufficient natural water pressure by accelerating the heat exchange process through forced circulation, thus shortening the cooling time. Stable water flow pressure prevents interruptions in the heat exchange process due to pressure fluctuations, ensuring that cooling efficiency remains at a high level. Enhanced controllability of water flow velocity allows the refrigeration system to flexibly adjust operating parameters according to different operating conditions, improving overall response performance.

[0036] In a preferred embodiment, the outer tube 12 is made of copper. By limiting the material of the outer tube 12 to copper, the excellent thermal conductivity of copper itself enhances the heat transfer capability of the refrigerant within the gap 13. Compared to conventional metals, copper has a faster thermal response speed, enabling rapid heat absorption and release as the refrigerant flows through the gap 13. Simultaneously, the ductility and plasticity of copper ensure that the outer tube 12 maintains structural integrity during the tight winding process, preventing tube breakage or decreased thermal conductivity due to repeated bending. This material selection also considers potential corrosion issues during long-term operation of the refrigeration system; the inherent antioxidant properties of copper extend the service life of the outer tube 12.

[0037] Of course, in other embodiments, the outer tube 12 can also be made of other metal materials, such as carbon steel, low alloy steel, stainless steel, copper-nickel alloy, aluminum alloy, titanium, etc.

[0038] In a preferred embodiment, the inner tube 11 is made of stainless steel. Using stainless steel for the inner tube 11 ensures its corrosion resistance when in contact with water, preventing rust from affecting water quality and cooling efficiency over long-term use, while also taking into account the material's thermal conductivity. The rigid structure of stainless steel can withstand water flow pressure, preventing refrigerant from mixing with water due to pipe deformation or rupture, thus ensuring the stability of the cooling process. Furthermore, the thermal conductivity of stainless steel helps accelerate heat exchange in a counter-current design, thereby improving the cooling effect.

[0039] Of course, in other embodiments, the inner tube 11 can also be made of other metal materials, such as carbon steel, low alloy steel, copper, copper-nickel alloy, aluminum alloy, titanium, etc.

[0040] In a preferred embodiment, the water reservoir 2 is made of stainless steel. By limiting the material of the water reservoir 2 to stainless steel, the high thermal conductivity of stainless steel improves the heat exchange efficiency between the water reservoir 2 and the refrigerant pipe 1 coiled around its periphery, thereby enhancing the cooling effect of the refrigerant on the water inside the water reservoir 2. The corrosion resistance of stainless steel prevents the water reservoir 2 from rusting during long-term contact with water and refrigerant, ensuring the service life of the device. Simultaneously, its chemical stability prevents the material from reacting with the water, ensuring water quality safety. This material selection addresses the problems of insufficient cooling effect and poor system durability caused by material defects from three aspects: thermal conductivity efficiency, structural reliability, and hygiene safety.

[0041] In a preferred embodiment, the refrigeration system includes a compressor 3, a condenser 4, a filter 5, and a capillary tube 6 connected in sequence, and the refrigerant inlet 120 of the outer tube 12 is connected to the outlet of the capillary tube 6.

[0042] In this embodiment, the basic framework of the refrigerant circulation loop is formed by sequentially connecting the compressor 3, condenser 4, filter 5, and capillary tube 6. The compressor 3 compresses the gaseous refrigerant into a high-temperature, high-pressure state; the condenser 4 dissipates heat and liquefies the high-temperature, high-pressure refrigerant; and the filter 5 filters impurities from the liquid refrigerant, ensuring system operational stability. Utilizing the throttling and pressure-reducing characteristics of the capillary tube 6, the high-pressure liquid refrigerant is transformed into a low-temperature, low-pressure mist. This structural design precisely controls the refrigerant phase change process, ensuring that the refrigerant entering the gap 13 of the refrigeration pipe 1 is in an optimal evaporation state, thereby achieving efficient heat exchange in the gap 13 and shortening the cooling time. The connection sequence of each component and the placement of the capillary tube 6 create a synergistic effect. The compressor 3 and condenser 4 work together to complete the refrigerant state conversion, and the filter 5 and capillary tube 6 combine to achieve flow control, ultimately improving the heat exchange efficiency of the refrigeration system.

[0043] In a preferred embodiment, the capillary tube 6 is spiral-shaped. By setting the capillary tube 6 to a spiral structure, its spatial extensibility increases the length of the refrigerant flow path, forming a meandering flow channel within a limited installation space. The centrifugal force generated by the spiral shape induces turbulence in the refrigerant, enhancing the heat exchange contact area with the tube wall, allowing the liquid refrigerant to fully complete the expansion process before entering the evaporation section. This structure, through the damping effect generated by the spiral bend, suppresses abrupt changes in refrigerant flow rate, ensuring a stable countercurrent flow of the refrigerant in the gap 13, thereby improving the refrigerant phase change efficiency and heat exchange uniformity.

[0044] In a preferred embodiment, a temperature sensor and a controller are also included. The probe of the temperature sensor extends into the water storage tank 2, and the controller is electrically connected to the temperature sensor and the compressor 3, respectively.

[0045] In this embodiment, the temperature sensor is a device used to detect the water temperature inside the water tank 2. Specifically, it can be implemented using a thermistor or thermocouple, with its probe directly contacting the water to obtain real-time temperature data. The controller is an electronic module that regulates the operation of the compressor 3 based on the temperature signal. Specifically, it can be implemented using a microprocessor or programmable logic controller (PLC). It receives the sensor signal and compares it with a preset threshold, then outputs control commands to the compressor 3. Specifically, the temperature sensor is configured to continuously monitor the water temperature inside the water tank 2 and transmit the detected data to the controller. The controller compares the received water temperature data with a preset target temperature. When the water temperature is higher than the target value, the controller sends a start signal to the compressor 3 to activate the refrigeration system; when the water temperature reaches the target value, the controller sends a stop signal to terminate the operation of the compressor 3. This closed-loop control mechanism ensures that the refrigeration system only starts when needed, avoiding energy waste and over-cooling caused by continuous operation of the compressor 3. In some specific embodiments, the temperature sensor can be installed on the top or side wall of the water tank 2, ensuring that the probe is completely submerged in water; the controller can be integrated into the circuit board of the refrigeration system and connected to the compressor 3 via a cable or wireless communication module. Compared to existing technologies, traditional refrigeration devices rely on fixed time cycles or manual operation to control the compressor 3, which cannot dynamically adjust its operating status according to the actual water temperature, easily leading to insufficient or excessive cooling. This embodiment, through real-time temperature feedback and automatic control, enables the compressor 3 to precisely match the operation with water temperature changes, realizing on-demand start and stop of the refrigeration system, effectively reducing ineffective cooling time, improving refrigeration efficiency, and avoiding energy waste caused by the water temperature in the water tank 2 falling below the set value.
