[0002] Chilled water equipment can produce water at temperatures below room temperature, meeting users' needs for low-temperature water. Therefore, chilled water equipment is becoming increasingly common in both commercial and residential settings.

[0003] In chilled water systems, the refrigeration components generate heat while cooling the water, which affects the cooling efficiency. To ensure efficiency, water-cooled heat dissipation structures are typically installed on the heat-generating parts of the refrigeration components. These structures utilize hot water exchange to dissipate heat from the refrigeration components, improving their efficiency and ensuring the system effectively provides chilled water to users. However, the heat carried away by the hot water exchange, along with the increased temperature of the exchange water, is often not effectively utilized but instead discharged or lost, resulting in significant waste and greatly reducing the material and energy utilization rates of the chilled water system. Utility Model Content

[0004] In view of this, this application provides a cooling water device that can effectively utilize the hot water exchanged to cool the heating part of the cooling component, thereby improving the material utilization rate of the cooling water device.

[0005] To solve the above-mentioned technical problems, one technical solution adopted in this application is: to provide a cooling water device, including a cooling component, a cooling water circuit, a sterilization inlet water circuit, a heat exchange water circuit, and a sterilization valve.

The heat exchange water circuit is at least connected to the sterilization inlet water circuit and is thermally connected to the heating section. The sterilization valve is connected to the sterilization inlet water circuit.

[0006] In one specific embodiment, the chilled water equipment is further provided with a sterilization water outlet, which is connected to the end of the chilled water circuit away from the sterilization water inlet, and is used to discharge water from the chilled water circuit.

[0007] In one specific embodiment, one end of the sterilization water outlet is connected to the cooling water outlet and the other end is connected to the heat exchange water outlet, and the water in the sterilization water outlet flows from the cooling water outlet to the heat exchange water outlet.

[0008] In one specific embodiment, the chilled water equipment further includes a first heating element connected to the sterilization water inlet; and / or, the chilled water equipment further includes a water inlet, one end of which is connected to the hot water exchange circuit and / or the chilled water circuit, and the other end is used to connect to a water source, and the sterilization water inlet is also connected to the end of the water inlet that is away from the hot water exchange circuit and / or the chilled water circuit.

[0009] In one specific embodiment, the cooling water circuit includes a cooling water inlet circuit, a cold water chamber, and a cooling water outlet circuit connected in sequence. The cold water chamber is thermally connected to the cooling unit, and the cooling water outlet circuit is used to output cold water. The sterilization water inlet circuit is connected to the cooling water inlet circuit.

[0010] In one specific embodiment, the cold water chamber includes a refrigeration chamber, a cold storage chamber, and a water passage.

[0011] In one specific embodiment, the chilled water equipment further includes a cold water valve, which is connected to the chilled water outlet circuit.

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0030] Chilled water equipment can produce water at temperatures below room temperature, meeting users' needs for low-temperature water. Therefore, chilled water equipment is becoming increasingly common in both commercial and residential settings.

[0031] In chilled water systems, the refrigeration components generate heat while cooling the water, which affects the cooling efficiency. To ensure efficiency, water-cooled heat dissipation structures are typically installed on the heat-generating parts of the refrigeration components. These structures utilize hot water exchange to dissipate heat from the refrigeration components, improving their efficiency and ensuring the system effectively provides chilled water to users. However, the heat carried away by the hot water exchange, along with the increased temperature of the exchange water, is often not effectively utilized but instead discharged or lost, resulting in significant waste and greatly reducing the material and energy utilization rates of the chilled water system.

[0032] In order to improve or solve the above technical problems, the inventors of this application, after long-term research, have proposed at least the following embodiments.

[0033] See Figure 1 , Figure 1 This is a schematic diagram of the water circuit structure of the first embodiment of the chilled water device provided in this application. The specific embodiments of this application provide a chilled water device 1, including a refrigeration component 2, a chilled water circuit 3, a sterilization inlet water circuit 5, a heat exchange water circuit 4, and a sterilization valve 53. The refrigeration component 2 is provided with a cooling section 21 and a heating section 22. The chilled water circuit 3 is thermally connected to the cooling section 21 and is used to prepare chilled water and output it to the chilled water outlet channel 8. The sterilization inlet water circuit 5 is connected to the chilled water circuit 3 after passing through the heating section 22. The heat exchange water circuit 4 is at least connected to the sterilization inlet water circuit 5 and is thermally connected to the heating section 22. The sterilization valve 53 is connected to the sterilization inlet water circuit 5. The chilled water outlet channel 8 is used to output chilled water to supply users.

[0034] In the structure provided in this specific embodiment, by setting up a hot water exchange path 4, a sterilization valve 53, and a sterilization inlet path 5, when the sterilization valve 53 is open, the high-temperature hot water flowing through the heating element 22 can be input into the cooling water path 3 through the sterilization inlet path 5, thereby using the high-temperature hot water to sterilize the cooling water path 3. This allows the water, after flowing through the hot water exchange path 4 and the heating element 22 for heat exchange, to be used again for the sterilization process of the cooling water path 3. This enables the secondary utilization of the hot water generated during the heat exchange process and the heat carried away by the hot water. Thus, while maintaining the cooling efficiency of the refrigeration unit 2 through heat exchange, the waste of hot water is avoided, and the material and energy utilization rates of the cooling water equipment 1 are improved.

[0035] Specifically, the cooling element 2 can be a semiconductor cooling element, which can include an N-type element and a P-type element connected in series. The N-type element and the P-type element respectively include N-type semiconductor material and P-type semiconductor material (e.g., bismuth telluride). When a direct current is applied to the semiconductor cooling element, i.e., when the cooling element 2 is working, the N-type semiconductor material and a piece of P-type semiconductor material of the semiconductor cooling element are connected to form an electric couple, thereby generating energy transfer. The current flows from the N-type element to the junction of the P-type element, absorbing heat and becoming the cooling section 21. The current flows from the P-type element to the junction of the N-type element, releasing heat and becoming the heating section 22.

[0036] See Figure 2 , Figure 2 This is a schematic diagram of the water circuit structure of the second embodiment of the chilled water equipment provided in this application. In a specific embodiment of this application, the chilled water equipment 1 is further provided with a sterilization water outlet 6, which is connected to the end of the chilled water circuit 3 away from the sterilization water inlet 5, and is used to discharge water from the chilled water circuit 3.

[0037] In the structure provided in this specific embodiment, after the high-temperature hot water is used as sterilization water and enters the cooling water circuit 3 from the sterilization inlet 5 for sterilization, it can be discharged from the cooling water circuit 3 through an independent sterilization outlet 6. This can prevent the sterilization water from stagnating in the cooling water circuit 3, thereby reducing the probability of the sterilization water contaminating the cooling water circuit 3. This can further ensure the water quality of the cold water prepared by the cooling water circuit 3, thereby improving the hygienic performance and stability of the cooling water equipment 1.

[0038] like Figure 3 As shown, Figure 3 This is a schematic diagram of the water circuit structure of the third embodiment of the chilled water equipment provided in this application. In a specific embodiment of this application, one end of the sterilization water outlet 6 is connected to the chilled water circuit 3, and the other end of the sterilization water outlet 6 is connected to the hot water exchange circuit 4. The water in the sterilization water outlet 6 flows from the chilled water circuit 3 to the hot water exchange circuit 4.

[0039] In the structure provided in this specific embodiment, the high-temperature hot water undergoes heat exchange during the sterilization process flowing through the cooling water circuit 3. Therefore, the temperature of the hot water in the sterilization outlet circuit 6 is lower than the temperature of the hot water in the sterilization inlet circuit 5. After the sterilization process is completed, the cooled hot water can flow back to the hot water circuit 4 and be used again to exchange heat with the heating element 22 of the cooling component 2. Not only can the heat generated by the heating element 22 be used to sterilize the cooling water circuit 3, but the hot water used for sterilization can also be recycled and reused to continue to exchange heat and cool the heating element 22. This improves both the energy utilization rate and the material utilization rate of the cooling water equipment 1.

[0040] like Figure 1As shown in a specific embodiment of this application, the chilled water device 1 further includes a first heating element 54, which is connected to the sterilization water inlet 5.

[0041] In the structure provided in this specific embodiment, a first heating element 54 is provided in the sterilization water inlet 5. When the temperature of the hot water in the hot water exchange circuit 4 does not reach a temperature sufficient to kill microorganisms, the first heating element 54 can be used to further heat the hot water flowing through the sterilization water inlet 5, thereby heating the hot water to a temperature sufficient to kill microorganisms, so that it can be used to perform high-temperature sterilization on the cooling water circuit 3, which can ensure the water quality of the cold water prepared by the cooling water circuit 3, thereby improving the hygienic performance and stability of the cooling water equipment 1.

[0042] Optionally, the chilled water equipment 1 may further include a water inlet path, one end of which is connected to the heat exchange water path 4 and / or the chilled water path 3, and the other end of which is connected to a water source. This allows water from the water source to be input into the heat exchange water path 4 for heat exchange, and / or into the chilled water path 3 for the preparation of chilled water. The water source may be an external tap water pipe, water treatment equipment, or the output end of a filter cartridge installed in the chilled water equipment 1. A sterilization water inlet path 5 may also be connected to the end of the water inlet path furthest from the heat exchange water path 4 and / or the chilled water path 3. This allows for sterilization of the water inlet path used to input water into the heat exchange water path 4 and / or the chilled water path 3, further ensuring the water quality of the chilled water prepared by the chilled water path 3, thereby improving the hygienic performance and stability of the chilled water equipment 1.

[0043] See Figures 1-3 In one specific embodiment of this application, the cooling water circuit 3 includes a cooling water inlet circuit 31, a cold water chamber 32, and a cooling water outlet circuit 33 connected sequentially. The cold water chamber 32 is thermally connected to the cooling component 2, and the cooling water outlet circuit 33 is used to output cold water. The sterilization water inlet circuit 5 is connected to the cooling water inlet circuit 31. The cooling water inlet circuit 31 is used to input water into the cold water chamber 32, the cold water chamber 32 is used to store water and prepare cold water using the cooling unit 21, and the cooling water outlet circuit 33 is used to output the cold water in the cold water chamber 32 to supply users.

[0044] In the structure provided in this specific embodiment, the high-temperature hot water can enter the cooling water inlet 31 through the sterilization inlet 5, and then sequentially perform a complete sterilization process on the cooling water inlet 31, the cold water chamber 32, and the cooling water outlet 33. Then, it is output to the outside of the cooling water circuit 3 through the cooling water outlet 33 for outputting cold water. This can perform a complete and thorough high-temperature sterilization process on the cooling water circuit 3, thereby ensuring the water quality of the cold water prepared by the cooling water circuit 3, and thus improving the hygienic performance and stability of the cooling water equipment 1.

[0045] Furthermore, an ultraviolet (UV) disinfection lamp may be installed in any of the cooling water inlet 31, the cold water chamber 32, and the cooling water outlet 33. The UV disinfection lamp is connected to the power supply of the cooling water equipment 1. When the UV disinfection lamp is turned on, it can sterilize the water flowing through the UV disinfection lamp in any of the cooling water inlet 31, the cold water chamber 32, and the cooling water outlet 33 with UV light.

[0046] Specifically, the hot water exchange circuit 4 may include a circulating water circuit 41 and a hot water exchange chamber 42. The circulating water circuit 41 has a high-temperature end 412 and a low-temperature end 411 at both ends. Water in the circulating water circuit 41 flows from the low-temperature end 411 to the high-temperature end 412. The high-temperature end 412 is connected to the top of the hot water exchange chamber 42, and the low-temperature end 411 is connected to the bottom of the hot water exchange chamber 42.

[0047] In the hot water exchange circuit 4, water enters the circulating water circuit 41 from the low temperature end 411 and exchanges heat with the heating element 22 as it flows along the circulating water circuit 41 towards the high temperature end 412. Therefore, the water temperature at the low temperature end 411 is lower and the water temperature at the high temperature end 412 is higher. The water with higher temperature enters the top of the hot water exchange chamber 42 from the high temperature end 412. As the water moves from the top to the bottom of the hot water exchange chamber 42, its temperature decreases, causing the water with lower temperature to return from the low temperature end 411 to the circulating water circuit 41.

[0048] Therefore, the sterilization water inlet 5 can be connected to the top of the high-temperature section and / or the hot water exchange chamber 42, so that the hot water with a higher temperature in the hot water exchange circuit 4 can be input into the cooling water circuit 3 for high-temperature sterilization.

[0049] See Figures 4-6 , Figure 4 This is a schematic diagram of the assembly structure of the cold water tank, heat exchanger, and hot water tank provided in this application. Figure 5 yes Figure 4 A schematic diagram of the cross-sectional structure shown in section AA. Figure 6 yes Figure 4 The cross-sectional view shown in Figure BB is a schematic diagram. The cold water cavity 32 can be formed inside the cold water tank 32a, the circulating water circuit 41 that exchanges heat with the heating element 22 can be set inside the heat exchanger 413, and the hot water cavity 42 can be formed inside the hot water tank 42a.

[0050] The refrigeration unit 2 is connected to the cold water tank 32a and the heat exchanger 413, with the refrigeration unit 21 facing into the cold water cavity 32, and the heating unit 22 thermally connected to the heat exchanger 413. Part of the circulating water path 41 is located inside the heat exchanger 413 for thermal connection with the heating unit 22, and the remaining circulating water path 41 is formed in a pipeline, with one end of the pipeline connected to the heat exchanger 413 and the other end connected to the hot water tank 42a, so that the circulating water path 41 in the pipeline can connect to the hot water cavity 42 inside the hot water tank 42a.

[0051] Because water with higher temperatures has lower density, the water in the hot water exchange chamber 42 exhibits a temperature distribution trend of gradually increasing from bottom to top. For example... Figure 6 As shown, in the vertical direction, a pipe with a high-temperature end 412 is connected to the upper end of the hot water exchange tank 42a, so that the high-temperature hot water output from the high-temperature end 412 can enter the upper layer of the hot water exchange cavity 42. A pipe with a low-temperature end 411 is connected to the lower end of the hot water exchange tank 42a, so that the circulating water circuit 41 can obtain low-temperature hot water from the lower layer of the hot water exchange cavity 42 through the low-temperature end 411, which is in line with the temperature distribution of the water in the hot water exchange cavity 42.

[0052] See Figure 2 , Figure 3 In a specific embodiment of this application, the cold water cavity 32 may specifically include a refrigeration cavity 321, a cold storage cavity 324, and a water passage 322. The refrigeration water device 1 also includes a water pump 323 connected to the water passage 322. The refrigeration cavity 321 is connected to the refrigeration inlet water passage 31 and the water passage 322, and the cold storage cavity 324 is connected to the water passage 322 and the refrigeration outlet water passage 33.

[0053] In the structure provided in this specific embodiment, when the water pump 323 is turned off, the high-temperature hot water is stored in the cooling chamber 321, which enables the cooling chamber 321 and the cooling water inlet 31 to be soaked and sterilized. This allows for thorough sterilization of the cooling water inlet 31 used for inputting water and the cooling chamber 321 used for preparing cold water, which is beneficial for improving the quality of the cold water output from the cooling chamber 321, thereby improving the quality of the cold water output from the cooling water equipment 1.

[0054] See Figure 2 , Figure 3 In one specific embodiment of this application, the chilled water equipment 1 further includes a cold water valve 34, which is connected to the chilled water outlet 33. By providing the cold water valve 34 in the chilled water outlet 33, when the water pump 323 is turned on and the cold water valve 34 is closed, the high-temperature hot water can enter the cold storage chamber 324 through the water passage 322 and be stored in the cold storage chamber 324, thereby achieving immersion sterilization of the cold storage chamber 324 and the chilled water outlet 33 upstream of the cold water valve 34. This allows for thorough sterilization of the cold storage chamber 324 used for storing cold water, which is beneficial for improving the water quality of the cold water output from the cold storage chamber 324, and thus improving the water quality of the cold water output by the chilled water equipment 1.

[0055] See Figure 2Specifically, the sterilization inlet water path 5 can be connected to the cooling water outlet path 33 upstream of the cooling water valve 34. When the cooling water valve 34 is closed, the sterilization water in the cooling water outlet path 33 can only enter the sterilization inlet water path 5, and thus output the cooling water path 3 through the sterilization outlet water path 6, without entering the cooling water outlet path 33 downstream of the cooling water valve 34. This prevents the sterilization water from contaminating the end of the cooling water outlet path 33 used to output cooling water. With this configuration, when the end of the cooling water outlet path 33 away from the cold storage chamber 324 is connected to the cooling water outlet channel 8 used to supply cooling water to users, the sterilization water will not enter the cooling water outlet channel 8, thus preventing contamination of the cooling water outlet channel 8 and ensuring the water quality of the water output from the cooling water outlet channel 8.

[0056] like Figures 1-3 As shown in a specific embodiment of this application, the chilled water device 1 further includes a filter element 7, which has an inlet end 71 and an outlet end 72. The heat exchange water circuit 4 and the chilled water circuit 3 are connected to the outlet end 72. Water entering the filter element 7 from the inlet end 71 can be filtered by the filter element 7 and then output from the outlet end 72. Therefore, water with better quality can be input into the heat exchange water circuit 4 for heat exchange, and water with better quality can be input into the chilled water circuit 3 for the preparation of chilled water.

[0057] When using hot water exchange to sterilize the cooling water circuit 3 at high temperature, since the hot water exchange is from the outlet 72 and has a better water quality, it will not introduce new impurities into the cooling water circuit 3 in addition to sterilization. This ensures the quality of the cold water output from the cooling water circuit 3 and improves the stability of the cold water output from the cooling water equipment 1.

[0058] The chilled water equipment 1 may also be provided with a water inlet channel 91, which is used to introduce external water into the chilled water equipment 1 for heat exchange or for preparing chilled water. The chilled water equipment 1 may also include a water inlet valve 911, which is connected to the water inlet channel 91.

[0059] like Figure 1 As shown, the water inlet channel 91 is connected to the water inlet end 71 of the filter element 7. Water from the chilled water device 1 enters the filter element 7 through the water inlet channel 91, and after being filtered by the filter element 7, it enters the chilled water circuit 3 through the water outlet end 72. It can be used to flush the chilled water circuit 3 or to prepare chilled water. Figure 2 , Figure 3 As shown, the water inlet channel 91 is connected to the heat exchange circuit 4. Water from the cooling water device 1 enters the heat exchange circuit 4 through the water inlet channel 91 and can exchange heat with the heating element 22.

[0060] See Figure 3Furthermore, the water outlet 72 can be connected to a purified water outlet channel 721, which is used to output purified water filtered by the filter element 7 to the outside of the chilled water equipment 1 to supply water with a temperature different from that of cold water, thereby improving the availability of the chilled water equipment 1.

[0061] See Figure 2 , Figure 3 In a specific embodiment of this application, the sterilization water inlet path 5 includes a first sterilization water path 51 and a second sterilization water path 52. One end of the first sterilization water path 51 is connected to the hot water exchange path 4, and the other end of the first sterilization water path 51 is connected to the water inlet 71. One end of the second sterilization water path 52 is connected to the water outlet 72, and the other end of the second sterilization water path 52 is connected to the cooling water path 3.

[0062] In the structure provided in this specific embodiment, the sterilization water path can specifically include two parts. The first sterilization water path 51 introduces high-temperature heat exchange water into the inlet 71 of the filter element 7, allowing the heat exchange water to be filtered by the filter element 7, thereby improving the water quality of the heat exchange water. Then, the second sterilization water path 52 inputs the filtered heat exchange water into the cooling water path 3. Since the heat exchange water is output from the outlet 72 and has relatively good water quality, it will not introduce new impurities into the cooling water path 3 in addition to sterilization, thereby ensuring the water quality of the cold water output from the cooling water path 3 and improving the water quality stability of the cold water output from the cooling water equipment 1.

[0063] like Figure 1 As shown in a specific embodiment of this application, the cooling water device 1 may further include a second heating element 521, which is connected to the second sterilization water path 52.

[0064] After the hot water flows through the first sterilization water path 51 and the filter element 7, the temperature of the hot water drops due to heat transfer between them. This may result in the hot water not reaching a sufficient temperature to adequately sterilize the cooling water path 3. In this specific embodiment, a second heating element 521 connected to the second sterilization water path 52 is provided. This second heating element 521 can reheat the water, ensuring that the temperature of the water entering the cooling water path 3 reaches a temperature sufficient for sterilization, thus guaranteeing the stability of sterilization in the cooling water path 3.
