Technical Field
The invention relates to the technical field of communication, in particular to a heat dissipation cabinet and a server node.
Background
In recent years, with the continuous development of internet technology, the integration level of electronic devices is required to be higher, and more highly integrated chips with large power consumption are applied to server nodes. In order to solve the problem of heating points in the server nodes, the server nodes and the cold plate can be attached together in a hard contact mode to transfer heat, and the attaching mode determines the heat transfer capacity, so that the method is a key technology of the scheme.
As shown in fig. 1, the industry solution is to attach the sides of the server node 101 to a cold plate. Specifically, a heat sink substrate 102 is added on a server node 101, the heat sink substrate 102 is connected with a copper plate 104 on the side surface through a heat pipe 103, and the copper plate 104 is closely attached to a cold plate 105 on a machine frame to take away heat.
The main problems in the prior art are as follows: the heat transfer path from the server node 101 to the cold plate 105 of the frame is too long, up to about 100mm, increasing the thermal resistance. The contact area between the copper plate 104 of the server node 101 and the cold plate 105 of the machine frame is limited by height, and cannot be large, so that the contact thermal resistance is large, and the maximum supporting heat dissipation power is limited. And the dissipated heat is drawn away through a plurality of heat pipes, so that the cost is higher.

Detailed Description
First, the overall structure of the heat dissipation cabinet shown in this embodiment is described as follows:
referring to fig. 2 and 3, the present embodiment provides a heat dissipation cabinet, which includes a cabinet body 200, a plurality of server nodes 201 installed in the cabinet body 200, and a plurality of cold plates 202 installed in the cabinet body 200.
Specifically, the cabinet body 200 shown in this embodiment is used to support and fix the server node 201 and the cold plate 202.
More specifically, the cold plate 202 of the present embodiment is used to dissipate heat dissipated by the server node 201.
As further shown in fig. 3, the server node 201 shown in this embodiment includes: the service chip is used for carrying out service processing, and the service chip can generate a large amount of heat when processing services.
In order to dissipate heat generated by the service chip during service processing, a cooling channel through which a cooling fluid flows is disposed inside the cold plate 202 shown in this embodiment.
Because the side surface of the server node 201 is attached to the cold plate 202, the heat generated by the service chip is transferred to the cold plate 202, and is cooled and dissipated by the cooling liquid in the cold plate 202.
In order to achieve the purpose of transferring the heat generated by the service chip to the cold plate 202, as shown in fig. 4, a service single board 400 may be further disposed inside the server node 201 shown in this embodiment, where the service single board 400 is fixedly disposed with the service chip 402, and a heat sink 401 is disposed in contact with the service chip 402.
Specifically, the first side surface of the heat sink 401 is attached to the service chip 402, and the second side surface of the heat sink 401 is connected to the cold plate 202, so that the heat sink 401 is configured to conduct heat generated in a process of processing services by the service chip 402 to the cold plate 202, so that the cold plate 202 dissipates heat of the service chip 402, and the efficiency of conducting heat from the service chip 402 to the cold plate 202 is improved.
Optionally, the heat sink 401 shown in this embodiment may be a heat pipe, or may also be a heat conducting material such as a heat conducting metal block, so as to ensure heat transfer.
The server node 201 and the cold plate 202 shown in this embodiment are detachable structures, that is, the server node 201 and the cold plate 202 shown in this embodiment are not integrally formed, so that the server node 201 and the cold plate 202 are not directly fixed together, and when the server node 201 is installed, the server node 201 only needs to be inserted into the cabinet body 200, so that the side surface of the server node 201 is attached to the cold plate 202, and further, the heat sink 401 included in the server node 201 is attached to the cold plate 202.
It can be seen that the cold plate 202 shown in this embodiment does not need to be plugged together with the server node 201, so that the server node 201 and the cold plate 202 are separated, the risk of liquid leakage can be avoided, and the potential safety hazard of the heat dissipation cabinet is reduced. And the heat dissipation rack of design like this can reduce the wiring on the server node.
Optionally, the cold plate 202 of the present embodiment may be removably mounted within the cabinet body 200 to facilitate maintenance.
In this embodiment, as shown in fig. 4, the side surface of the server node 201 attached to the cold plate 202 is a first inclined plane structure, and specifically, the side surface of the server node 201 attached to the cold plate 202 and the vertical direction of the heat dissipation cabinet form a first preset angle, so that the side surface of the server node 201 attached to the cold plate 202 is the first inclined plane structure.
In this embodiment, the size of the first preset angle is not limited, and the embodiment takes the structure that the first preset angle is an acute angle as an example for illustration.
The cold plate 202 with the side that the server node 201 was laminated is second inclined plane shape structure, and is specific, cold plate 202 with the side that the server node 201 was laminated with the vertical direction of heat dissipation rack is the second and predetermines the angle, so that cold plate 202 with the side that the server node 201 was laminated is second inclined plane shape structure.
In this embodiment, the size of the second preset angle is not limited, and the second preset angle is taken as an obtuse angle structure for an exemplary explanation.
Specifically, in this embodiment, the first preset angle and the second preset angle are matched, so that the first inclined plane structure and the second inclined plane structure are arranged in parallel, and the server node 201 can be attached to the cold plate 202.
Optionally, the server node 201 shown in this embodiment may have a wedge-shaped structure, so that the first inclined plane structure is formed on a side surface of the server node 201, and the cold plate 202 may have a wedge-shaped structure, so that the second inclined plane structure is formed on a side surface of the cold plate 202.
If the heat dissipation efficiency of the cold plate 202 to the server node 201 is improved, the heat sink 401 shown in this embodiment is in a wedge-shaped structure, so that the first inclined plane-shaped structure is formed on the side surface of the heat sink 401.
As shown in fig. 5 and 6, in order to mount the server node 201 inside the cabinet body 200, wrench mechanisms 601 are respectively provided at two end portions of a side surface of the server node 201.
The wrench mechanism 601 is used for applying a force F to the server node 201, and the force F is shown in fig. 7. The force F is resolved into a first force F1 and a second force F2 on the first ramp shaped structure.
The first acting force F1 is perpendicular to the press fit surface 600, and as shown in fig. 4, the press fit surface 600 is formed between the first inclined plane structure and the second inclined plane structure. The first force F1 is used to press the server node 201 against the side of the cold plate 202 to enable the heat sink 401 to closely fit the cold plate 202, so that the cold plate 202 can dissipate heat from the heat sink 401, and the heat of the heat sink 401 is conducted from the heat sink 401 to the cold plate 202.
The second force F2 is used to overcome the friction between the first and second ramp-shaped structures, and the server node 201 can be installed inside the cabinet body 200 by the second force F2.
In this embodiment, if the acting force F is too large, the cold plate 202 may be crushed, but if the acting force F is too small, the heat sink 401 and the cold plate 202 may be in poor contact, so as to reduce the heat dissipation efficiency of the cold plate 202 for dissipating the heat of the heat sink 401, where the wrench mechanism 601 shown in this embodiment can control the acting force F within a target preset range, so that the acting force F within the target preset range can enable the heat sink 401 and the cold plate 202 to be in close contact, and the server node 201 can be successfully installed inside the cabinet body 200.
In order to control the acting force F within the target preset range by the wrench mechanism 601 shown in the present embodiment, refer to fig. 8 and 9:

Specifically, a buckle 803 is formed at an end of the wrench 801, and a receiving groove 804 is formed at a position of the cabinet body 200 opposite to the buckle 803.
When the wrench 801 receives a rotational force input by a user, and the wrench 801 can rotate through the rotation shaft 802, the latch 803 can be latched inside the receiving groove 804 or the latch 803 can be disengaged from the receiving groove 804.
In this embodiment, as shown in fig. 8, a structural diagram of the wrench structure 601 in an initial state is shown, and when the wrench structure 601 is in the initial state, the buckle 803 is buckled inside the receiving groove 804.
When the server node 201 needs to be installed inside the cabinet body 200, as shown in fig. 9, the wrench 801 may be rotated to disengage the buckle 803 from the inside of the receiving groove 804, so that a user may apply a force F to the server node 201 through the wrench 801.
In this embodiment, in order to control the acting force F within a target preset range, the wrench mechanism 601 further includes a compression spring 805, and the compression spring 805 in a compressed state is used to control the acting force F within a preset range.
Specifically, a first end of the compressed spring 805 is fixed inside the server node 201, and a second end of the compressed spring 805 is connected to the rotating shaft 802.
Specifically, the server node 201 is provided with a sliding slot 806, and the rotating shaft 802 can slide along the guiding direction of the sliding slot 806.
In a specific application process, in the process of applying an acting force to the wrench 801, the rotating shaft 802 may slide along the guide of the sliding slot 806, and in the process of sliding the rotating shaft 802, the pressure spring 805 applies a pressure to the rotating shaft 802 in a direction opposite to the direction of the acting force F, so that the sliding stroke of the rotating shaft 802 through the sliding slot 806 is controlled, and the pressure of the pressure spring 805 can control the acting force F within the target preset range, so that the acting force F within the target preset range can enable the heat sink 401 to be in close contact with the cold plate 202, and the server node 201 can be successfully installed inside the cabinet body 200.
The following explains the beneficial effects of the heat dissipation cabinet shown in this embodiment: because the first side surface of the heat spreader 401 shown in this embodiment is attached to the service chip 402, and the second side surface of the heat spreader 401 is connected to the cold plate 202, the heat spreader 401 can conduct heat generated in the process of processing services by the service chip 402 to the cold plate 202, and direct heat dissipation is performed through the heat spreader 401, so that a heat dissipation transmission path from the service chip 402 to the cold plate 202 is reduced, and the efficiency of heat dissipation of the service chip 402 is effectively improved;
by adopting the structure shown in the embodiment, the contact area between the server node 201 and the cold plate 202 can be effectively improved, the heat dissipation effect of the cold plate 202 on the server node 201 is effectively improved, and the heat dissipation cabinet shown in the embodiment does not need to adopt a remote heat pipe, so that the cost of the heat dissipation cabinet is reduced.
In addition, in this embodiment, the server node 201 may be installed inside the heat dissipation cabinet 200 or the server node 201 may be taken out from the heat dissipation cabinet 200 through a wrench mechanism, and a pressure spring is provided inside the wrench mechanism shown in this embodiment, so that an acting force exerted on the server node 201 by the wrench mechanism can be controlled within the target preset range through pre-compression of the pressure spring, so that the acting force F within the target preset range can make the heat sink 401 and the cold plate 202 tightly contact, and the server node 201 can be successfully installed inside the cabinet body 200.
