Description

Technical Field

[0001] This application relates to the field of seawater desalination technology, and in particular to a seawater desalination system that utilizes waste heat from an underwater server. Background Technology

[0002] Currently, the demand for freshwater is increasing dramatically, but freshwater resources are limited. Therefore, how to desalinate seawater into drinkable freshwater has become a major issue.

[0003] In related technologies, seawater is generally heated to convert the water in the seawater into water vapor, thereby separating the water and salt in the seawater. Finally, the water vapor is cooled to obtain fresh water.

[0004] However, seawater is usually heated using electricity, which wastes energy. Summary of the Invention

[0005] This application provides a seawater desalination system that utilizes waste heat from an underwater server to solve the problem of power consumption during the seawater desalination process.

[0006] This application provides a seawater desalination system utilizing waste heat from an underwater server, comprising a reaction device, a first heat-conducting component, a first pump body, a housing, a heating element, a second heat-conducting component, a second pump body, and a first heat exchanger. The reaction device has a reaction chamber, and an inlet, a freshwater outlet, and a brine outlet communicating with the reaction chamber are provided on the reaction device. The first heat-conducting component includes a heating channel, the outlet end of which is connected to the inlet, and the inlet end of the heating channel is used to communicate with seawater. The first pump body is used to drive the flow of seawater within the heating channel. The housing has a receiving cavity. The heating element is disposed within the receiving cavity. The second heat-conducting component has a heat-conducting channel formed inside, the liquid inlet end of which is connected to a water source, and the second heat-conducting component is used to absorb the heat emitted by the heating element. The second pump body is used to drive the flow of liquid within the heat-conducting channel. The liquid inlet end of the first heat exchanger is connected to the liquid outlet end of the heat-conducting channel, and the first heat exchanger is in contact with the first heat-conducting component.

[0007] The seawater desalination system utilizing waste heat from an underwater server in this application allows the second heat-conducting component to absorb the heat generated by the heating element, thus transferring the heat to the water within the heat-conducting channel, resulting in high-temperature water flowing out of the heat-conducting channel.

[0008] Since the inlet of the first heat exchanger is connected to the outlet of the heat conduction channel, and the first heat exchanger is in contact with the first heat conduction element, when the external seawater flows into the reaction chamber through the first heat conduction element, the heat in the high-temperature water in the heat conduction channel can be conducted to the seawater in the first heat conduction element to heat the seawater. During the heating process, some of the water in the seawater will be converted into water vapor, while the other part of the water in the seawater will carry a large amount of salt to form brine. Then, both the brine and the water vapor will enter the reaction chamber. At this time, the water vapor can be discharged directly or converted into liquid water through the fresh water outlet, while the brine will be discharged through the brine outlet, thereby achieving seawater desalination to obtain fresh water.

[0009] Because this application utilizes the waste heat generated by the heating element when heating seawater, it saves energy compared to electricity. Furthermore, since the heat generated by the heating element is absorbed, heat dissipation from the heating element is achieved.

[0010] In some embodiments of this application, the housing includes a first heat-conducting wall panel. The second heat-conducting element includes a second heat-conducting wall panel, and the first heat-conducting wall panel is in contact with the second heat-conducting wall panel.

[0011] The first and second heat-conducting wall plates are used as heat-conducting media to conduct the heat generated by the heating element to the water in the second heat-conducting component, thereby achieving heat transfer.

[0012] In some embodiments of this application, the second heat-conducting wall plate is located above the first heat-conducting wall plate.

[0013] As hot air rises, the heat generated by the heating element flows towards the location of the first heat-conducting wall plate, allowing the first heat-conducting wall plate to better absorb the heat generated by the heating element and thus better conduct the heat from the first heat-conducting wall plate to the second heat-conducting wall plate, which is more conducive to heating the water inside the first heat-conducting element.

[0014] In some embodiments of this application, the second heat-conducting element is located within the receiving cavity.

[0015] The heat generated by the heating element is dissipated into the cavity. Since the second heat-conducting element is located inside the cavity, the heat in the air can be conducted to the water inside the second heat-conducting element, thereby achieving heat transfer.

[0016] In some embodiments of this application, the seawater desalination system utilizing waste heat from an underwater server also includes a temperature sensor for detecting the actual temperature value of the liquid in the heat conduction channel, and the second pump is turned on or off according to the actual temperature value.

[0017] By setting a temperature sensor, the temperature of the liquid in the heat conduction channel is accurately monitored, so that the water temperature entering the first heat exchanger is kept at a suitable level, which can better heat the seawater in the first heat conduction element and thus achieve seawater desalination.

[0018] In some embodiments of this application, the first heat-conducting element includes multiple heat-conducting pipes, each heat-conducting pipe having a sub-channel formed inside it. The liquid inlet end of the sub-channel is used to communicate with seawater, and the liquid outlet end of the sub-channel is connected to the inlet. The heat-conducting pipes pass through the first heat exchanger, and the multiple sub-channels form a heating channel.

[0019] By setting up multiple heat pipes to transport seawater, and since the multiple heat pipes pass through the first heat exchanger, the first heat exchanger can fully contact the heat pipes, thus improving the heating efficiency of the seawater in the heat pipes and thereby improving the efficiency of seawater desalination.

[0020] In some embodiments of this application, the reaction apparatus includes a reaction vessel, a cooling device, a vapor-water separator, and a water receiving tray. A reaction chamber is formed on the reaction vessel, with an inlet, a fresh water outlet, and a brine outlet also formed on the reaction vessel. The cooling device is disposed within the reaction chamber and is capable of contacting the water vapor entering the reaction chamber. The vapor-water separator is disposed within the reaction chamber and is located at the inlet. The water receiving tray is disposed within the reaction chamber and is located below the cooling device, for collecting fresh water dripping from the cooling device and guiding the fresh water to the fresh water outlet.

[0021] With the above setup, after water vapor and brine enter the reaction chamber, they first pass through a steam-water separation plate. The steam-water separation plate can prevent the brine from rising further and filter out any small amount of brine that may be present in the water vapor, so that the brine can be discharged through the brine outlet. The water vapor will then pass through the steam-water separation plate and come into contact with the cooling device above. During the contact process, the water vapor will liquefy into fresh water upon cooling. The fresh water will then drip onto the water receiving tray below and be guided to the fresh water outlet, thereby achieving seawater desalination.

[0022] In some embodiments of this application, the cooling device includes a second heat exchanger, the inlet end of which is connected to a cryogenic liquid, and the outlet end of which is connected to the outside of the reaction chamber.

[0023] A second heat exchanger is used to cool the water vapor entering the reaction chamber, causing it to liquefy into fresh water. Because the second heat exchanger uses external water to cool the water vapor, it is simpler, more convenient, and more energy-efficient than other cooling devices.

[0024] In some embodiments of this application, a seawater desalination system utilizing waste heat from an underwater server includes an inlet pipe, an outlet pipe, a third pump body, and a connecting pipe. The inlet end of the inlet pipe is connected to seawater, and the outlet end of the inlet pipe is connected to the inlet end of a heating channel. A first pump body is mounted on the inlet pipe. The inlet end of the outlet pipe is connected to a brine outlet. A third pump body is mounted on the outlet pipe. The inlet end of the connecting pipe is connected to the inlet pipe, and its inlet end is located between the first pump body and the outlet end of the inlet pipe. The outlet end of the connecting pipe is connected to the outlet pipe, and its outlet end is located between the third pump body and the inlet end of the outlet pipe.

[0025] By installing a connecting pipe, some seawater can enter the drain pipe through the connecting pipe to flush the drain pipe and the third pump body, thus preventing salt stains from clogging the drain pipe and the third pump body.

[0026] In some embodiments of this application, an exhaust pipe and a vacuum pump are included. The inlet end of the exhaust pipe is connected to the reaction chamber, and the outlet end of the exhaust pipe is connected to the outside of the reaction chamber. The vacuum pump is used to drive the gas flow within the exhaust pipe.

[0027] By setting up an exhaust pipe and a vacuum pump to expel the gas from the reaction chamber, the reaction chamber is made into a vacuum state. In this way, even if the seawater in the heating channel is at a low temperature and has not boiled, when the seawater enters the reaction chamber, the vacuum state of the reaction chamber can lower the boiling point of the seawater, thereby causing the seawater to boil and vaporize. This can reduce the heating temperature for seawater desalination, making seawater desalination easier to achieve. Attached Figure Description

[0044] Currently, the demand for freshwater is increasing dramatically, but freshwater resources are limited. Therefore, how to desalinate seawater into drinkable freshwater has become a major issue.

[0045] Based on this, such as Figure 1 As shown, this application provides a seawater desalination system 1 utilizing waste heat from an underwater server, comprising a reaction device 11, a first heat-conducting component 12, a first pump body 13, and a heat source. The reaction device 11 has a reaction chamber 11A inside, and an inlet 11B, a freshwater outlet 11C, and a brine outlet 11D communicating with the reaction chamber 11A are provided on the reaction device 11A. The first heat-conducting component 12 includes a heating channel 12A, the outlet end of which communicates with the inlet 11B, and the inlet end of the heating channel 12A is used to communicate with seawater. The first pump body 13 is used to drive the flow of seawater within the heating channel 12A. The heat source is used to heat the first heat-conducting component 12.

[0046] With the above setup, during seawater desalination, the first pump 13 is activated, allowing external seawater to flow into the reaction chamber 11A through the heating channel 12A. Since the heat source can heat the first heat-conducting element 12, during the heating process, some of the water in the seawater within the first heat-conducting element 12 will be converted into water vapor, while the other part of the water in the seawater will carry a large amount of salt to form brine. Then, both the brine and the water vapor will enter the reaction chamber 11A. At this time, the water vapor can be discharged directly or converted into liquid water through the freshwater outlet 11C, while the brine will be discharged through the brine outlet 11D, thereby achieving seawater desalination to obtain fresh water.

[0047] It is understandable that the positions of brine outlet 11D and freshwater outlet 11C should be reasonably set according to the needs to ensure that water vapor or freshwater after water vapor liquefaction can be discharged to the outside of reaction chamber 11A through freshwater outlet 11C.

[0048] At the same time, ensure that the brine can be discharged to the outside of the reaction chamber 11A through the brine outlet 11D. For example, make the position of the inlet 11B higher than the position of the brine outlet 11D so that the brine can be discharged through the brine outlet 11D.

[0049] For example, the material of the first heat-conducting element 12 may include copper, aluminum, etc., which have good thermal conductivity and are inexpensive.

[0050] In some embodiments, such as Figure 2 As shown, this application provides a specific structure of a reaction apparatus 11, which includes a reaction vessel 111, a cooling device 112, a vapor-water separator 113, and a water receiving tray 114. A reaction chamber 11A is located on the reaction vessel 111, and an inlet 11B, a fresh water outlet 11C, and a brine outlet 11D are also located on the reaction vessel 111. The cooling device 112 is disposed within the reaction chamber 11A and is capable of contacting the water vapor entering the reaction chamber 11A. The vapor-water separator 113 is disposed within the reaction chamber 11A and is located at the inlet 11B. The water receiving tray 114 is disposed within the reaction chamber 11A and is located below the cooling device 112, for collecting fresh water dripping from the cooling device 112 and guiding the fresh water to the fresh water outlet 11C.

[0051] With the above setup, after water vapor and brine enter the reaction chamber 11A, they first pass through the steam-water separation plate 113. The steam-water separation plate 113 can prevent the brine from rising further and filter out any small amount of brine that may be present in the water vapor, so that the brine can be discharged through the brine outlet 11D. The water vapor will pass through the steam-water separation plate 113 and come into contact with the cooling device 112 above. During the contact process, the water vapor will be cooled and liquefied into fresh water. The fresh water will then drip onto the water receiving pan 114 below and be guided to the fresh water outlet 11C, thereby achieving seawater desalination.

[0052] It is understandable that the water receiving tray 114 should have a water receiving trough, which is used to collect fresh water dripping from the self-cooling device 112.

[0053] It should be explained that the steam-water separator plate 113 refers to a device that prevents water from passing through, but allows water vapor to pass through.

[0054] In other embodiments, the reaction apparatus 11 may consist only of a reaction vessel 111 and a steam-water separation plate 113. Thus, after water vapor and brine enter the reaction chamber 11A, they first pass through the steam-water separation plate 113. The steam-water separation plate 113 prevents the brine from rising further and filters out any small amount of brine that may be present in the water vapor, allowing the brine to exit through the brine outlet 11D. The water vapor, however, flows through the steam-water separation plate 113 to the fresh water outlet 11C and is eventually discharged outside the reaction vessel 111. Subsequently, other equipment collects and liquefies the water vapor to obtain fresh water.

[0055] In order to drain the fresh water on the water receiving tray 114 to the outside of the reaction chamber 11A, such as Figure 2 As shown, the seawater desalination system 1 utilizing waste heat from an underwater server in this application further includes a water pipe 16, a water pump 161, and a water collection container 162. The inlet end of the water pipe 16 is connected to a water receiving tank, and the outlet end of the water pipe 16 is connected to the outside of the reaction chamber 11A. The water pump 161 is mounted on the water pipe 16, so that the outlet end of the water pipe 16 is connected to the water collection container 162.

[0056] In this way, after the water pump 161 is started, the fresh water in the water tank can be discharged into the water collection container 162 through the water pipe 16, thereby realizing the collection of fresh water for subsequent use.

[0057] In some examples, such as Figure 3 As shown, the cooling device 112 may include a second heat exchanger 1121. The inlet end of the second heat exchanger 1121 is used to communicate with a cryogenic liquid, and the outlet end of the second heat exchanger 1121 is communicated with the outside of the reaction chamber 11A.

[0058] In this way, when the low-temperature liquid passes through the second heat exchanger 1121, the temperature of the second heat exchanger 1121 is relatively low. When the water vapor comes into contact with the higher-temperature second heat exchanger 1121, the water vapor will liquefy into fresh water and adhere to the second heat exchanger 1121. Then, it will drip from the second heat exchanger 1121 onto the water receiving tray 114 below it, thereby realizing the liquefaction of water vapor and the collection of fresh water.

[0059] The aforementioned cryogenic liquid can be external seawater, thus utilizing a natural cold source to liquefy water vapor and reduce costs. Alternatively, the aforementioned cryogenic liquid can also be a refrigerant.

[0060] In other examples, the cooling device 112 may also include a heat pipe, with the evaporation end of the heat pipe located inside the reaction chamber 11A and in contact with water vapor, and the condensation end of the heat pipe located outside the reaction chamber 11A and cooled by a cold source. For example, heat dissipation fins may be provided such that they contact the condensation end of the heat pipe to dissipate heat from the condensation section of the heat pipe.

[0061] By installing heat pipes, heat can be circulated between the evaporation end and the condensation end of the heat pipes, thereby cooling water vapor and liquefying it.

[0062] In some embodiments, such as Figure 3 As shown, the seawater desalination system 1 utilizing waste heat from an underwater server further includes an exhaust pipe 14 and a vacuum pump 15. The inlet end of the exhaust pipe 14 is connected to the reaction chamber 11A, and the outlet end of the exhaust pipe 14 is connected to the outside of the reaction chamber 11A. The vacuum pump 15 is used to drive the gas flow within the exhaust pipe 14.

[0063] With the above settings, after the vacuum pump 15 is started, the vacuum pump 15 can extract the gas in the reaction chamber 11A, thereby making the reaction chamber 11A a vacuum state. In this way, even if the seawater in the heating channel 12A is at a low temperature and has not boiled, when the seawater enters the reaction chamber 11A, because the reaction chamber 11A is in a vacuum state, the boiling point of the seawater can be lowered, so that the seawater boils and vaporizes. This can reduce the heating temperature of seawater desalination and make seawater desalination easier to achieve.

[0064] By using vacuum pump 15 to expel the gas from reaction chamber 11A, the vacuum level within reaction chamber 11A can reach 90% to 94%, for example, 90%, 91%, 92%, 93%, 94%, etc. This can lower the boiling point of seawater to between 35℃ and 45℃, for example, 35℃, 36℃, 37℃, 38℃, 40℃, 45℃, etc.

[0065] In some embodiments, to facilitate the delivery of seawater into the heating channel 12A, such as Figure 4 As shown, the seawater desalination system 1 utilizing waste heat from an underwater server provided in this application also includes an inlet pipe 17. The inlet end of the inlet pipe 17 is used to communicate with seawater, and the outlet end of the inlet pipe 17 is connected to the inlet 11B end of the heating channel 12A. The first pump body 13 is disposed on the inlet pipe 17.

[0066] In this way, after the first pump body 13 is started, seawater can be guided into the heating channel 12A through the water inlet pipe 17. The length of the water inlet pipe 17 can be reasonably set according to the requirements, which facilitates the layout of the first heat conduction element 12 and the reaction device 11.

[0067] In some embodiments, for the convenience of seawater extraction, such as Figure 4 As shown, the seawater desalination system 1 utilizing waste heat from an underwater server provided in this application also includes a surface platform 18, which is placed on the surface of the seawater, and the reaction device 11 and the like are placed on the surface platform 18.

[0068] By placing the reaction device 11 and other components on the floating platform 18, the reaction device 11 can be placed closer to the seawater, making it easier to pump seawater into the reaction device 11 using the inlet pipe 17. This simplifies the pipeline layout.

[0069] In order to make the water platform 18 float on the water surface, multiple support columns can be installed at the bottom of the water platform 18, with one end of the support column connected to the bottom of the water platform 18 and the other end of the support column connected to the bottom of the water, so that the water platform 18 can be suspended on the water surface.

[0070] Alternatively, in order to make the water platform 18 sit on the water surface, the water platform 18 can be made of a suspending material, so that the water platform 18 can be directly suspended on the water surface.

[0071] In some embodiments, in order to drain the brine from the reaction chamber 11A, such as Figure 4 As shown, the seawater desalination system 1 utilizing waste heat from an underwater server provided in this application also includes a drain pipe 19 and a third pump body 20. The inlet end of the drain pipe 19 is connected to the brine outlet 11D, and the third pump body 20 is used to drive the liquid flow in the drain pipe 19.

[0072] By providing a drain pipe 19 and a third pump 20, the third pump is activated when discharging brine, so that the brine in the reaction chamber 11A can be discharged to the outside of the reaction chamber 11A via the drain pipe 19. Due to the presence of the drain pipe 19, the brine can be discharged to any suitable location via the drain pipe 19, which facilitates the layout of the reaction apparatus 11.

[0073] For example, brine can be drained into an external collection tank to collect it, which facilitates subsequent processing to obtain table salt.

[0074] Based on this, such as Figure 4 As shown, the seawater desalination system 1 utilizing waste heat from an underwater server provided in this application also includes a connecting pipe 21. The inlet end of the connecting pipe 21 is connected to the inlet pipe 17. The inlet end of the connecting pipe 21 is located between the first pump body 13 and the outlet end of the inlet pipe 17. The outlet end of the connecting pipe 21 is connected to the drain pipe 19. The outlet end of the connecting pipe 21 is located between the inlet end of the drain pipe 19 and the third pump body 20.

[0075] With the above setup, after the brine is discharged using the drain pipe 19 and the third pump body 20, the first pump body 13 is then started. In this way, a portion of the seawater in the inlet pipe 17 will enter the drain pipe 19 through the connecting pipe 21 to flush the drain pipe 19 and the third pump body 20. This can prevent salt stains from clogging the drain pipe 19 and the third pump body 20, ensuring that the drain pipe 19 and the third pump body 20 work normally and discharge the brine smoothly.

[0076] In related technologies, in order to heat the first heat-conducting element 12, i.e. to provide a heat source, electric heating is generally used to heat the first heat-conducting element 12, but this wastes electrical energy.

[0077] Based on this, such as Figure 5 As shown, the seawater desalination system 1 utilizing waste heat from an underwater server provided in this application further includes a housing 22, a heating element 23, a second heat-conducting element 24, a second pump body 25, and a first heat exchanger 26. The housing 22 has an internal cavity 22A. The heating element 23 is disposed within the cavity 22A. A heat-conducting channel 24A is formed inside the second heat-conducting element 24. The liquid inlet end of the heat-conducting channel 24A is connected to a water source, and the second heat-conducting element 24 is used to absorb the heat emitted by the heating element 23. The second pump body 25 is used to drive the liquid flow within the heat-conducting channel 24A. The liquid inlet end of the first heat exchanger 26 is connected to the liquid outlet end of the heat-conducting channel 24A, and the liquid outlet end of the first heat exchanger 26 is connected to seawater. The first heat exchanger 26 is in contact with the first heat-conducting element 12.

[0078] In this way, the heat generated by the heating element 23 can be conducted to the second heat conductor 24, and then to the water in the heat conduction channel 24A, so that the water flowing out of the heat conduction channel 24A is high temperature water.

[0079] Since the inlet of the first heat exchanger 26 is connected to the outlet of the heat conduction channel 24A, and the first heat exchanger 26 is in contact with the first heat conduction element 12, when the external seawater flows into the reaction chamber 11A through the first heat conduction element 12, the heat in the high-temperature water in the heat conduction channel 24A can be conducted to the seawater in the first heat conduction element 12 to heat the seawater.

[0080] Because this application utilizes the waste heat generated by the heating element 23 when heating seawater, it saves energy compared to electricity. Furthermore, since the heat generated by the heating element 23 is absorbed, heat dissipation from the heating element 23 is achieved.

[0081] In some embodiments, such as Figure 6As shown, the first heat-conducting element 12 includes a plurality of heat-conducting pipes 121. A sub-channel 121A is formed inside the heat-conducting pipe 121. The liquid inlet end of the sub-channel 121A is used to communicate with seawater, and the liquid outlet end of the sub-channel 121A is connected to the inlet 11B. The heat-conducting pipe 121 passes through the first heat exchanger 26, and the outer wall of the heat-conducting pipe 121 is in contact with the first heat exchanger 26. The plurality of sub-channels 121A form a heating channel 12A.

[0082] By setting up multiple heat pipes 121, seawater is transported using multiple heat pipes 121. Since multiple heat pipes 121 pass through the first heat exchanger 26, the first heat exchanger 26 can fully contact the heat pipes 121, which can improve the heating efficiency of the seawater in the heat pipes 121, thereby improving the efficiency of seawater desalination.

[0083] Furthermore, due to the increased number of heat pipes 121, without reducing the flow rate of the heating channel 12A, the diameter of each heat pipe 121 can be set to be smaller, that is, each heat pipe 121 can be set to be thinner. This reduces the water flow rate in each heat pipe 121, which can better heat the water in the heat pipe 121, improve the heating effect, and facilitate seawater vaporization.

[0084] The cross-section of the heat pipe 121 can be a regular shape such as a ring or a square, or it can be an irregular shape.

[0085] In addition, the heat pipe 121 can be configured with 8, 9, 10, etc. The specific configuration can be adjusted according to requirements.

[0086] Alternatively, the first heat-conducting element 12 may consist of only a heat-conducting pipe 121, which is in direct contact with the surface of the first heat exchanger 26 to achieve heat conduction.

[0087] In some embodiments, such as Figure 7 As shown, the seawater desalination system 1 utilizing waste heat from an underwater server provided in this application also includes a temperature sensor 27. The temperature sensor 27 is used to detect the actual temperature value of the liquid in the heat conduction channel 24A, and the second pump body 25 is turned on or off according to the actual temperature value.

[0088] By setting a temperature sensor 27, the temperature of the liquid in the heat conduction channel 24A is accurately monitored, so that the water temperature entering the first heat exchanger 26 is kept at a suitable level, which can better heat the seawater in the first heat conduction element 12, thereby achieving seawater desalination.

[0089] It is understandable that a certain amount of water should exist in the heat conduction channel 24A in the initial stage, and the second pump body 25 will be started or stopped according to the temperature detected by the temperature sensor 27.

[0090] In some examples, the second pump 25 can be turned on or off by a controller. Specifically, the second pump 25 is electrically connected to the controller, and the temperature sensor 27 is electrically connected to the controller, so that the controller controls the start or stop of the second pump 25 based on the actual temperature value detected by the temperature sensor 27.

[0091] Alternatively, a temperature display instrument can be set up to display the actual temperature value detected by the temperature sensor 27 on the temperature display instrument. Then, the actual temperature value can be read manually, and the second pump body 25 can be turned on or off manually.

[0092] In some examples, the second pump 25 is activated when the actual temperature value is greater than or equal to the preset temperature value, and the second pump 25 is deactivated when the actual temperature value is less than the preset temperature value, so that the heat generated by the heating element 23 is conducted to the water in the heat conduction channel 24A.

[0093] This ensures that the water entering the first heat exchanger 26 is at a suitable temperature, thus fully heating the seawater in the first heat-conducting element 12 to vaporize the seawater and achieve seawater desalination.

[0094] For example, the preset temperature value can be between 50°C and 70°C, such as 50°C, 55°C, 60°C, or 70°C. Of course, the preset temperature can also be any other suitable value.

[0095] It is understandable that the preset temperature value should be set according to the vacuum level inside reactor 111. The higher the vacuum level inside reactor 111, the lower the boiling point of seawater, so the preset temperature value can be appropriately reduced. Conversely, the lower the vacuum level inside reactor 111, the higher the boiling point of seawater, so the preset temperature value needs to be increased.

[0096] For example, the temperature sensor 27 can be disposed within the heat conduction channel 24A to detect the actual temperature value of the liquid within the heat conduction channel 24A. Alternatively, the temperature sensor 27 can be disposed outside the heat conduction channel 24A to detect the actual temperature value of the liquid within the heat conduction channel 24A.

[0097] In some embodiments, in order to conduct the heat generated by the heating element 23 to the second heat-conducting element 24, such as Figure 8 As shown, the aforementioned housing 22 includes a first heat-conducting wall plate 221. The second heat-conducting component 24 includes a second heat-conducting wall plate 241. The first heat-conducting wall plate 221 is in contact with the second heat-conducting wall plate 241, and the heat generated by the heating element 23 can be conducted to the second heat-conducting wall plate 241 through the first heat-conducting wall plate 221.

[0098] With the above configuration, the first heat-conducting wall plate 221 and the second heat-conducting wall plate 241 can serve as heat-conducting media. When the heating element 23 emits heat, the heat will be emitted into the air inside the receiving cavity 22A, and then conducted to the first heat-conducting wall plate 221. It will then be conducted to the second heat-conducting wall plate 241 through the first heat-conducting wall plate 221, and then enter the heat-conducting channel 24A. In this way, the heat generated by the heating element 23 is conducted to the heat-conducting channel 24A to heat the liquid inside the heat-conducting channel 24A.

[0099] For example, the materials of the first heat-conducting wall plate 221 and the second heat-conducting wall plate 241 may include copper, aluminum, etc. Copper and aluminum have good thermal conductivity and are inexpensive.

[0100] In this case, the wall panels of the second heat-conducting element 24, except for the second heat-conducting wall panel 241, are set as heat-insulating wall panels. This can prevent the heat loss in the water inside the second heat-conducting element 24 and allow more heat to be transferred to the first heat-conducting element 12 through the first heat exchanger 26, thereby improving the heat utilization rate.

[0101] In some examples, in order to ensure that the first heat-conducting wall plate 221 and the second heat-conducting wall plate 241 have sufficient contact area, the first heat-conducting wall plate 221 and the second heat-conducting wall plate 241 can be made to face each other. This maximizes the contact area between the first heat-conducting wall plate 221 and the second heat-conducting wall plate 241, thereby improving the heat conduction efficiency between the first heat-conducting wall plate 221 and the second heat-conducting wall plate 241.

[0102] Of course, the first heat-conducting wall plate 221 and the second heat-conducting wall plate 241 may not be in complete contact.

[0103] For example, the first heat-conducting wall panel 221 can be a flat plate, which facilitates its processing. Alternatively, the first heat-conducting wall panel 221 can also be a curved plate.

[0104] Similarly, the second heat-conducting wall plate 241 can also be a flat plate, which facilitates the processing of the second heat-conducting wall plate 241. Alternatively, the second heat-conducting wall plate 241 can also be a curved plate.

[0105] In some embodiments, such as Figure 8 As shown, the second heat-conducting wall plate 241 is located above the first heat-conducting wall plate 221. Since hot air rises, the heat generated by the heating element 23 flows towards the location of the first heat-conducting wall plate 221. This allows the first heat-conducting wall plate 221 to better absorb the heat generated by the heating element 23, thereby better transferring the heat from the first heat-conducting wall plate 221 to the second heat-conducting wall plate 241, which is more conducive to heating the water in the heat-conducting channel 24A.

[0106] In other embodiments, such as Figure 9 As shown, the second heat-conducting element 24 is located inside the receiving cavity 22A. In this way, when the heat generated by the heating element 23 is dissipated into the receiving cavity 22A, the hot air inside the receiving cavity 22A will directly contact the second heat-conducting element 24, so that the heat in the hot air can be conducted to the water inside the second heat-conducting element 24, thereby realizing the transfer of heat.

[0107] In some embodiments, such as Figure 9 As shown, the power generation system utilizing waste heat from an underwater server provided in this application also includes a filter 28, which is disposed at the inlet of the heat conduction channel 24A and is used to filter the liquid entering the heat conduction channel 24A.

[0108] In this way, impurities can be prevented from entering the heat conduction channel 24A, thus keeping the water in the heat conduction channel 24A clean and preventing blockage. This ensures that the water in the heat conduction channel 24A can smoothly enter the first heat exchanger 26, thereby smoothly transferring the heat in the water to the first heat conduction element 12 to heat the seawater in the heating channel 12A, thus ensuring the normal realization of seawater desalination.

[0109] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
