[0044] The following will describe the implementation methods of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0045] It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centrally arranged component.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0047] Some embodiments of the present application propose an immersion heat dissipation device, including a box body, a coolant, a box cover, a first fan and a second fan; the box body is provided with a cavity, the cavity is filled with coolant, and a server to be cooled is installed in the cavity and immersed in the coolant; the box cover is provided on the box body and can close the cavity; the first fan and the second fan are relatively arranged on the box body and are located above the cavity; the first fan and the second fan have the same wind direction to form an air wall above the cavity to cover the coolant exposed from the cavity.

[0048] The immersion heat dissipation device is configured by arranging a first fan and a second fan on opposite sides of a box body, respectively. The first fan and the second fan are used to form an air wall above the cavity to cover the liquid surface of the coolant exposed from the cavity. When the coolant cools the server, the steam generated encounters the low-temperature air wall and liquefies and then flows back into the cavity, thereby avoiding the loss of the coolant.

[0049] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0050] Please also see Figure 1 and Figure 2, one embodiment of the present application proposes a liquid immersed cabinet 200. The liquid immersed cabinet 200 includes an immersion heat dissipation device 100 and a server 201. The server 201 is arranged in the immersion heat dissipation device 100. The immersion heat dissipation device 100 is used to carry the server 201 and perform heat dissipation operations on the server 201. The immersion heat dissipation device 100 includes a box body 10, a box cover 30, a coolant 20, a first fan 40 and a second fan 50. The box body 10 is provided with a cavity 101. The cavity 101 is filled with coolant 20. The server 201 is installed in the cavity 101 and immersed in the coolant 20. The box cover 30 is arranged on the box body 10 and can close the cavity 101. The first fan 40 and the second fan 50 are relatively arranged on the box body 10 and are located above the cavity 101. The first fan 40 and the second fan 50 have the same wind direction, so as to form an air wall 103 above the cavity 101 to cover the coolant 20 exposed from the cavity 101 .

[0051] In one embodiment, the coolant 20 is an insulating, non-volatile, non-flammable, non-corrosive, non-phase-changing liquid with a boiling point of approximately 50-60° C., but not limited thereto. The boiling point of the coolant 20 is higher than the temperature of air.

[0052] Since the air temperature is generally 20-30°C, the air wall 103 formed by the operation of the first fan 40 and the second fan 50 to flow air covers the cavity 101, and the temperature is close to the air temperature. The temperature of the coolant 20 rises due to cooling the server 201. When the steam generated by the gasification of the coolant 20 flows along the box 10 toward the box cover 30, it will be blocked by the air wall 103, and the high-temperature steam will condense into liquid when encountering the low-temperature air wall 103 and flow back into the cavity 101, avoiding the loss of the coolant 20.

[0053] In one embodiment, the wind directions of the first fan 40 and the second fan 50 are respectively parallel to the cavity 101, but are not limited thereto. For example, the wind directions of the first fan 40 and the second fan 50 may also form an acute angle with the cavity 101, as long as the air wall 103 formed by the first fan 40 and the second fan 50 is located above the cavity 101 and covers the liquid surface of the coolant 20 exposed from the cavity 101, so that the coolant 20 in the cavity 101 is blocked by the air wall 103 when evaporating.

[0054] The immersion heat dissipation device 100 further includes a sensor 60 and a controller 70. The sensor 60 is disposed on the housing 10 and is used to detect the open or closed state of the housing cover 30 relative to the housing 10. The controller 70 is disposed on the housing 10 and is electrically connected to the sensor 60, the first fan 40 and the second fan 50, respectively. When the sensor 60 detects that the housing cover 30 is in an open state, the controller 70 controls the first fan 40 and the second fan 50 to work. When the sensor 60 detects that the housing cover 30 is in a closed state, the controller 70 controls the first fan 40 and the second fan 50 to stop working. When the housing cover 30 is in a closed state, the coolant 20 will not evaporate and lose, and the first fan 40 and the second fan 50 will not work, thereby reducing energy loss.

[0055] The box body 10 includes a first side wall 11 and a second side wall 13 that are arranged oppositely, and a third side wall 15 and a fourth side wall 17 that are arranged oppositely. The third side wall 15 is located between the first side wall 11 and the second side wall 13. The box cover 30 is rotatably arranged on the third side wall 15, and can be rotated toward the fourth side wall 17 to cover the box body 10, thereby closing the cavity 101. The first fan 40 is arranged on the first side wall 11. The second fan 50 is arranged on the second side wall 13. The number of the first fan 40 and the second fan 50 is respectively multiple. The multiple first fans 40 are sequentially arranged on the first side wall 11 and connected to both ends of the first side wall 11, and the multiple second fans 50 are sequentially arranged on the second side wall 13 and connected to both ends of the second side wall 13, so that the air wall 103 formed by the multiple first fans 40 and the multiple second fans 50 blowing air can cover the upper surface of the coolant 20 exposed from the cavity 101.

[0056] It is understood that in other embodiments, the number of the first fan 40 and the number of the second fan 50 may be one respectively. The first fan 40 may not be connected to the two ends of the first side wall 11, and the second fan 50 may not be connected to the two ends of the second side wall 13. As long as the first fan 40 and the second fan 50 are arranged opposite to each other, and the air wall 103 formed by the blowing air can cover the liquid surface of the coolant 20 exposed from the cavity 101, the coolant 20 can be blocked by the air wall 103 when evaporating upward.

[0057] The immersion heat sink 100 further includes a first rotating member 81 and a second rotating member 82. The first rotating member 81 is rotatably disposed on the first side wall 11. The first fan 40 is disposed on the first rotating member 81. The second rotating member 82 is rotatably disposed on the second side wall 13. The second fan 50 is disposed on the second rotating member 82. When the box cover 30 is in the open state, the first rotating member 81 and the second rotating member 82 rotate to respectively drive the first fan 40 and the second fan 50 to rotate to a relative position.

[0058] The first fan 40 includes a first air inlet 41 and a first air outlet 43. The second fan 50 includes a second air inlet 51 and a second air outlet 53. When the box cover 30 is opened relative to the box body 10, the first air inlet 41 is opposite to the second air outlet 53. One of the first fan 40 and the second fan 50 inhales air and the other exhausts air, and the wind directions of the first fan 40 and the second fan 50 are the same, so that an air wall 103 can be formed above the cavity 101.

[0059] When the box cover 30 is closed relative to the box body 10, the first air inlet 41 and the second air outlet 53 are respectively opposite to the cavity 101. The box cover 30 is provided with a groove 31. When the box cover 30 is closed relative to the box body 10, the first fan 40 and the second fan 50 are respectively rotated to positions substantially parallel to the cavity 101 to be accommodated in the groove 31 of the box cover 30, thereby reducing the size of the box cover 30.

[0060] It is understood that in other embodiments, the first rotating member 81 and the second rotating member 82 may also be omitted. When the box cover 30 is covered on the box body 10 , the depth of the groove 31 of the box cover 30 increases to accommodate the first fan 40 and the second fan 50 .

[0061] The immersion heat sink 100 further includes a first isolating member 91 and a second isolating member 92. The first isolating member 91 is disposed on the side of the first side wall 11 facing the second side wall 13, and is located between the cavity 101 and the first fan 40. The second isolating member 92 is disposed on the side of the second side wall 13 facing the first side wall 11, and is located between the cavity 101 and the second fan 50. When the box cover 30 is in a closed state relative to the box body 10, the first isolating member 91 and the second isolating member 92 isolate the first fan 40 and the second fan 50 from the coolant 20, respectively, to prevent the coolant 20 from evaporating upward and condensing and adhering to the first fan 40 and the second fan 50, and to prevent the liquid coolant 20 from being thrown out of the box body 10 due to the centrifugal force when the first fan 40 and the second fan 50 are in operation, thereby further reducing the loss of the coolant 20.

[0062] The immersion heat dissipation device 100 is configured by arranging a first fan 40 and a second fan 50 on opposite sides of a housing 10, respectively. The first fan 40 and the second fan 50 are used to form an air wall 103 above the cavity 101 to cover the liquid surface of the coolant 20 exposed from the cavity 101. When the coolant 20 cools the server 201, the vapor formed by the coolant 20 encounters the low-temperature air wall 103 and liquefies and then flows back into the cavity 101, thereby avoiding the loss of the coolant 20.

[0063] In addition, those skilled in the art may also make other changes within the spirit of the present application. Of course, these changes made according to the spirit of the present application should be included in the scheme disclosed in the present application.
