The cross section of the heat transfer pipe 121 may be a regular shape such as a circular ring shape or a square frame shape, or may be an irregular shape.

In addition, the heat transfer pipes 121 may be provided in 8, 9, 10, etc. The device can be specifically set according to the requirements.

Alternatively, the first heat conductive member 12 may include only one heat conductive pipe 121, such that the heat conductive pipe 121 directly contacts the surface of the first heat exchanger 26, thereby achieving heat conduction.

In some embodiments, as shown in fig. 7, the seawater desalination system 1 using waste heat of an underwater server provided by the present application further includes a temperature sensor 27, where the temperature sensor 27 is used to detect an actual temperature value of the liquid in the heat conducting channel 24A, and the second pump body 25 is opened or closed according to the actual temperature value.

By arranging the temperature sensor 27, the temperature of the liquid in the heat conduction channel 24A is accurately monitored, so that the water temperature in the first heat exchanger 26 is kept appropriate, the seawater in the first heat conduction member 12 can be heated better, and further the seawater desalination is realized.

It will be appreciated that in an initial phase, a certain amount of water should be present in the heat-conducting channel 24A, and the second pump body 25 is subsequently activated or deactivated in accordance with the temperature detected by the temperature sensor 27.

In some examples, the second pump body 25 may be controlled to open or close by a controller. Specifically, the second pump body 25 is electrically connected to the controller, and the temperature sensor 27 is electrically connected to the controller, so that the controller controls the activation or the deactivation of the second pump body 25 according to the actual temperature value detected by the temperature sensor 27.

Alternatively, a temperature display instrument may be provided, the actual temperature value detected by the temperature sensor 27 may be displayed on the temperature display instrument, and then the actual temperature value may be manually read, and then the second pump body 25 may be manually controlled to be opened or closed.

In some examples, the second pump body 25 is started when the actual temperature value is greater than or equal to the preset temperature value, and the second pump body 25 is closed when the actual temperature value is less than the preset temperature value, so that heat generated by the heat generating component 23 is conducted into the water in the heat conducting channel 24A.

This ensures that the water entering the first heat exchanger 26 is at a proper temperature, so that the seawater in the first heat conducting member 12 can be sufficiently heated to gasify the seawater, thereby achieving desalination of the seawater.

The preset temperature value may be, for example, between 50 ℃ and 70 ℃, for example, 50 ℃, 55 ℃, 60 ℃ or 70 ℃. Of course, the preset temperature may be any other suitable value.

It can be understood that the magnitude of the preset temperature value should be set according to the vacuum degree in the reaction kettle 111, and the higher the vacuum degree in the reaction kettle 111 is, the lower the boiling point of the seawater is, so that the preset temperature value can be properly reduced. Conversely, the lower the vacuum degree in the reaction vessel 111, the higher the boiling point of seawater, and thus the preset temperature value needs to be increased.

For example, a temperature sensor 27 may be provided in the heat conduction path 24A to detect an actual temperature value of the liquid in the heat conduction path 24A. Alternatively, the temperature sensor 27 may be disposed outside the heat conduction path 24A to detect an actual temperature value of the liquid in the heat conduction path 24A.

In some embodiments, in order to enable the heat generated by the heat generating component 23 to be conducted into the second heat conducting member 24, as shown in fig. 8, the case 22 includes a first heat conducting wall 221. The second heat conducting member 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 heat generated by the heat generating component 23 can be conducted to the second heat conducting wall plate 241 through the first heat conducting wall plate 221.

Through the above arrangement, the first heat-conducting wall plate 221 and the second heat-conducting wall plate 241 can be used as heat-conducting media, when the heating element 23 emits heat, the heat can be emitted to the air in the accommodating cavity 22A, then is conducted to the first heat-conducting wall plate 221, then is conducted to the second heat-conducting wall plate 241 through the first heat-conducting wall plate 221, and then enters the heat-conducting channel 24A, so that the heat generated by the heating element 23 is conducted to the heat-conducting channel 24A, and the heating of the liquid in the heat-conducting channel 24A is realized.

For example, the materials of the first and second heat conductive wall plates 221 and 241 may include copper, aluminum, etc., which have good heat conductive properties and are inexpensive.

In this case, the wall plates of the second heat conducting member 24 other than the second heat conducting wall plate 241 are heat insulating wall plates, so that heat dissipation in the water in the second heat conducting member 24 can be avoided, and more heat can be conducted to the first heat conducting member 12 through the first heat exchanger 26, so that the heat utilization rate is improved.

In some examples, 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 may be aligned with the second heat-conducting wall plate 241, so that the contact area of the first heat-conducting wall plate 221 and the second heat-conducting wall plate 241 may be maximized, thereby improving the heat conduction efficiency between the first heat-conducting wall plate 221 and the second heat-conducting wall plate 241.

Of course, the first heat-conductive wall plate 221 and the second heat-conductive wall plate 241 may not be completely contacted.

Illustratively, the first heat-conducting wall plate 221 may be a flat plate as a whole, which may facilitate the processing of the first heat-conducting wall plate 221. Alternatively, the first heat-conducting wall plate 221 may be a curved plate.

Similarly, the second heat-conducting wall plate 241 may be a flat plate, so that the second heat-conducting wall plate 241 may be processed conveniently. Alternatively, the second heat conductive wall plate 241 may be a curved plate.

In some embodiments, as shown in fig. 8, the second thermally conductive wall plate 241 is located above the first thermally conductive wall plate 221. Because the hot air can rise, the heat generated by the heating element 23 can flow to the position where the first heat conducting wall plate 221 is located, so that the first heat conducting wall plate 221 can better absorb the heat generated by the heating element 23, and the heat on the first heat conducting wall plate 221 is better conducted to the second heat conducting wall plate 241, so that the water in the heat conducting channel 24A can be heated more conveniently.

In other embodiments, as shown in fig. 9, the second thermally conductive member 24 is positioned within the receiving chamber 22A. In this way, after the heat generated by the heat generating component 23 is dissipated into the accommodating cavity 22A, the hot air in the accommodating cavity 22A is directly contacted with the second heat conducting member 24, so that the heat in the hot air can be conducted into the water in the second heat conducting member 24, and heat transfer is realized.

In some embodiments, as shown in fig. 9, the power generation system using the waste heat of the underwater server further includes a filter 28, where the filter 28 is disposed at the water inlet of the heat conducting channel 24A, for filtering the liquid entering the heat conducting channel 24A.

In this way, impurities can be prevented from entering the heat conducting channel 24A, so that water in the heat conducting channel 24A can be kept clean, and the heat conducting channel 24A is prevented from being blocked, so that water in the heat conducting channel 24A can be ensured to smoothly enter the first heat exchanger 26, and heat in the water is smoothly conducted into the first heat conducting piece 12, so that seawater in the heating channel 12A is heated, and normal implementation of seawater desalination is ensured.

The foregoing is merely illustrative of specific embodiments of the present application, and the scope of the present application is not limited thereto, but any changes or substitutions within the technical scope of the present application should be covered by the scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
