The terminology used herein in the description of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
The application provides an immersed heat dissipation device, which comprises a box body, cooling liquid, a box cover, a first fan and a second fan, wherein the box body is provided with a cavity, the cooling liquid is filled in the cavity, a server to be cooled is arranged in the cavity and immersed in the cooling liquid, the box cover is arranged on the box body and can seal the cavity, the first fan and the second fan are oppositely arranged on the box body and are positioned above the cavity, and the wind directions of the first fan and the second fan are the same so as to form a gas wall covering the cooling liquid exposed from the cavity above the cavity.
The immersed heat dissipation device is characterized in that the first fan and the second fan are respectively arranged on two opposite sides of the box body, the first fan and the second fan are utilized to form a gas wall covering the liquid level of the cooling liquid exposed out of the cavity, and when the cooling liquid cools the server, steam formed by the cooling liquid is liquefied by the gas wall with low temperature and then flows back into the cavity, so that the loss of the cooling liquid is avoided.
Some embodiments of the present application are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without collision.
Referring to fig. 1 and 2, an embodiment of the application provides a liquid immersion cabinet 200. The liquid immersion cabinet 200 includes an immersion type heat sink 100 and a server 201. The server 201 is disposed in the immersion type heat sink 100. The immersion heat sink 100 is used for carrying the server 201 and performing heat dissipation operation on the server 201. The submerged radiator 100 includes a case 10, a case cover 30, a coolant 20, a first fan 40, and a second fan 50. The case 10 is provided with a cavity 101. The cavity 101 is filled with the cooling liquid 20. The server 201 is installed in the cavity 101 and immersed in the cooling liquid 20. The cover 30 is provided on the case 10 and can close the cavity 101. The first fan 40 and the second fan 50 are disposed on the case 10 opposite to each other and above the cavity 101. The wind directions of the first fan 40 and the second fan 50 are the same to form an air wall 103 covering the cooling liquid 20 exposed from the cavity 101 above the cavity 101.
In one embodiment, the cooling fluid 20 is an insulating, non-volatile, non-flammable, non-corrosive, non-phase change fluid having a boiling point of approximately 50-60 ℃, but is not limited thereto. The boiling point of the cooling liquid 20 is higher than the temperature of the air.
Since the temperature of the air is generally 20-30 ℃, the air walls 103 formed by the operation of the first fan 40 and the second fan 50 to flow the air are covered over the cavity 101, and the temperature is close to that of the air. When the temperature of the cooling liquid 20 rises due to the cooling of the server 201, the steam generated by the gasification of the cooling liquid 20 flows along the direction of the box body 10 towards the box cover 30, the steam is blocked by the air wall 103, and the steam with high temperature is condensed into liquid to flow back into the cavity 101 when meeting the air wall 103 with low temperature, so that the loss of the cooling liquid 20 is avoided.
In one embodiment, the wind directions of the first fan 40 and the second fan 50 are parallel to the cavity 101, but not limited thereto. For example, the wind directions of the first fan 40 and the second fan 50 may be respectively at an acute angle to the cavity 101, so 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 cooling liquid 20 exposed from the cavity 101, so that the cooling liquid 20 in the cavity 101 is blocked by the air wall 103 when evaporating.
The submerged heat sink 100 also includes an inductor 60 and a controller 70. The sensor 60 is provided on the case 10 and detects an opened or closed state of the cover 30 with respect to the case 10. The controller 70 is disposed on the case 10 and electrically connected to the inductor 60, the first fan 40 and the second fan 50, respectively. When the inductor 60 detects that the cover 30 is in the opened state, the controller 70 controls the first fan 40 and the second fan 50 to operate. When the inductor 60 detects that the cover 30 is in the closed state, the controller 70 controls the first fan 40 and the second fan 50 to stop operating. When the cover 30 is closed, the cooling liquid 20 is not evaporated, the first fan 40 and the second fan 50 are not operated, and the energy loss is reduced.
The case 10 includes first and second sidewalls 11 and 13 disposed opposite to each other, and third and fourth sidewalls 15 and 17 disposed opposite to each other. The third side wall 15 is located between the first side wall 11 and the second side wall 13. The cover 30 is rotatably provided on the third side wall 15 and is rotatable toward the fourth side wall 17 to cover the case 10, thereby closing the cavity 101. The first fan 40 is disposed on the first sidewall 11. The second fan 50 is disposed on the second sidewall 13. The number of the first fans 40 and the second fans 50 is plural, respectively. The plurality of first fans 40 are sequentially disposed on the first side wall 11 and connected to both ends of the first side wall 11, and the plurality of second fans 50 are sequentially disposed on the second side wall 13 and connected to both ends of the second side wall 13, so that an air wall 103 formed by blowing air by the plurality of first fans 40 and the plurality of second fans 50 can be covered above the liquid level of the cooling liquid 20 exposed from the cavity 101.
It is understood that in other embodiments, the number of the first fans 40 and the second fans 50 may be one. The first fan 40 may not be connected to both ends of the first side wall 11, and the second fan 50 may not be connected to both ends of the second side wall 13. The first fan 40 and the second fan 50 are disposed opposite to each other, and the air wall 103 formed by blowing air may cover the liquid surface of the cooling liquid 20 exposed from the cavity 101, so that the cooling liquid 20 may be blocked by the air wall 103 when evaporating upward.
The submerged radiator 100 further includes a first rotating member 81 and a second rotating member 82. The first rotating member 81 is rotatably provided 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 cover 30 is in an 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 opposite positions.
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 cover 30 is opened with respect to the case 10, the first air inlet 41 is opposed to the second air outlet 53. One of the first fan 40 and the second fan 50 sucks air and the other discharges air, and the first fan 40 and the second fan 50 have the same wind direction so that an air wall 103 can be formed above the chamber 101.
When the cover 30 is closed with respect to the case 10, the first air inlet 41 and the second air outlet 53 are respectively opposite to the cavity 101. The cover 30 is provided with a recess 31. When the cover 30 is closed relative to the case 10, the first fan 40 and the second fan 50 are respectively rotated to a position substantially parallel to the cavity 101 to be received in the recess 31 of the cover 30, thereby reducing the size of the cover 30.
It will be appreciated that in other embodiments, the first and second rotating members 81, 82 may be omitted. When the cover 30 is covered on the case 10, the depth of the groove 31 of the cover 30 is increased to accommodate the first fan 40 and the second fan 50.
The submerged heat sink 100 further includes a first spacer 91 and a second spacer 92. The first spacer 91 is disposed on a side of the first sidewall 11 facing the second sidewall 13 and is located between the cavity 101 and the first fan 40. The second spacer 92 is disposed on a side of the second sidewall 13 facing the first sidewall 11 and located between the cavity 101 and the second fan 50. When the case cover 30 is closed relative to the case 10, the first and second spacers 91 and 92 isolate the first and second fans 40 and 50 from the cooling liquid 20, respectively, so that the cooling liquid 20 is prevented from evaporating upward and condensing and adhering to the first and second fans 40 and 50, and the cooling liquid 20 in a liquid state is thrown out of the case 10 due to the centrifugal force when the first and second fans 40 and 50 are operated, thereby further reducing the loss of the cooling liquid 20.
The submerged radiator 100 forms the air wall 103 covering the liquid surface of the cooling liquid 20 exposed from the cavity 101 above the cavity 101 by arranging the first fan 40 and the second fan 50 at opposite sides of the case 10, respectively, and when the cooling liquid 20 cools the server 201, the formed steam is liquefied by the air wall 103 having a low temperature and then flows back into the cavity 101, thereby avoiding the loss of the cooling liquid 20.
Further, other variations within the spirit of the present application will occur to those skilled in the art, and it is intended that all such variations be included within the scope of the present application.
