Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

With the development of china electronic technology, more and more electronic devices have been widely used, and the server 2 is an important component in the electronic devices, and provides computing services. Typically, the servers 2 in the machine room are placed in the cabinet, and the servers 2 generate a large amount of heat, and the heat is accumulated in the cabinet 1, so that the temperature of the servers 2 increases, and the operation of the servers 2 is slowed down. In order to increase the operation speed of the server 2, it is generally necessary to cool the cooling cabinet of the server 2, so that the temperature of the server 2 in the cabinet 1 is reduced.

In general, the liquid cooling server 2 is connected to a heat dissipating component in the server 2 from the rear end of the server 2 through a hot and cold pipe, absorbs heat generated by components of the server 2, and then transfers the heat to a heat dissipating device such as a cooling tower or a cooling plate through the flow of cooling liquid, so that the cooling liquid is cooled and recycled.

However, the heat dissipation method of the liquid cooling server 2 has the following disadvantages: 1. the water inlet pipe and the water outlet pipe of the server 2 are in single circulation, and cooling liquid does not flow between the servers 2 in the cabinet and between the heat dissipation components 201 in the servers 2, so that the heat dissipation efficiency is reduced, and energy is not saved.

Embodiments of the present invention are described below with reference to fig. 1 to 17.

According to an embodiment of the present invention, as shown in fig. 1,2, 3 and 4, in one aspect, there is provided a server cabinet, including a cabinet body 1, a water inlet pipeline assembly 3, a water outlet pipeline assembly 4, a water diversion pipe 5, a first waterway switching element 6 and a control module. The cabinet body 1 is used for bearing a plurality of servers 2 which are sequentially arranged along the height direction; the water inlet pipeline assembly 3 comprises a water inlet main pipeline 301 and a water inlet branch pipeline 302, wherein the water inlet main pipeline 301 is used for being connected with cooling liquid, one end of the water inlet branch pipeline is connected with the water inlet main pipeline 301, and the other end of the water inlet branch pipeline is connected with a water inlet of the server 2; the water outlet pipeline assembly 4 comprises a water outlet main pipeline 401 and a water outlet branch pipeline 402, wherein the water outlet main pipeline 401 is used for outputting cooling liquid, one end of the water outlet main pipeline 401 is connected with a water outlet of the server 2, and the other end of the water outlet main pipeline 401 is connected with the water outlet main pipeline 401. One end of the water diversion pipe 5 is connected with the water outlet of the first server, the other end of the water diversion pipe is connected with the water inlet of the second server, and the first server is positioned below the second server. The first waterway switching element 6 is disposed between the water diversion pipe 5 and the water outlet branch pipe 402, and can be switched between a first state in which the first waterway switching element 6 can block the water diversion pipe 5 and open the water outlet branch pipe 402, and a second state in which the first waterway switching element 6 can open the water diversion pipe 5 and block the water outlet branch pipe 402. The control module is in communication connection with the first waterway switching element 6 and can control the first waterway switching element 6 to switch between a first state and a second state.

In the server cabinet of the embodiment of the application, the water diversion pipe 5 is connected between the water outlet of the first server and the water inlet of the second server, and the heat generation amount of each server 2 in the cabinet is assumed to be the same, but the heat can be transferred upwards, so that the temperature of the upper layer of the cabinet is higher than the temperature of the lower layer, and the heat dissipation efficiency of the upper layer server 2 is also reduced; on the basis, the lower server 2 is not fully loaded, the generated heat is low, and the temperature of the discharged cooling liquid is not high. Both reasons can enable the cooling liquid of the lower server 2 to flow out and then further cool the upper server 2, so that the recycling of the cooling liquid in the cabinet is achieved, and the energy is saved.

In the using process of the server cabinet provided by the embodiment of the application, when the first waterway switching element 6 is in the second state, the cooling liquid flowing out of the water outlet of the first server can flow into the water inlet of the second server, so that the second server is cooled continuously, the utilization rate of the cooling liquid is improved, the heat dissipation efficiency of the server cabinet is improved, and the energy-saving effect is good. When the temperature of the cooling liquid flowing out of the water outlet of the first server is higher, the first waterway switching element 6 can be switched to the first state, so that the cooling liquid at the water outlet of the first server can directly flow into the water outlet pipeline assembly 4, and the heat exchange effect of the second server is not influenced.

In one embodiment, the server rack further comprises a plurality of first temperature measuring elements 7 and a control module. Each first temperature measuring element 7 is capable of measuring the temperature at the water outlet of one server 2. The control module is in communication connection with the first waterway switching element 6 and can control the first waterway switching element 6 to switch between a first state and a second state according to the detection result of the first temperature measuring element 7.

Through such setting, when the temperature of first server delivery port department is less than the temperature of second server delivery port department, control module can switch first water route switching element 6 to the second state to make the coolant liquid obtain abundant utilization, and when the temperature of first server delivery port department is higher than or equal to the temperature of second server delivery port department, control module can switch first water route switching element 6 to the first state, so that the coolant liquid of first server delivery port department flows into in the outlet pipeline subassembly 4 directly, in order to avoid influencing the radiating effect of second server.

The control module may include a programmable logic control unit (such as a PLC or a CPU), a memory, and electronic components connected to the programmable logic control unit, etc., which are well known to those skilled in the art, and will not be described in detail herein.

As an alternative embodiment, the first waterway switching element 6 may alternatively be switched manually.

Through so setting, when the temperature of the coolant liquid of water inlet department of second server is less than 0 ℃, first water route component can be switched to the third state to make the coolant liquid of first server delivery port department flow into in the second server, thereby carry out the intensification to a certain extent to the coolant liquid of water inlet department of second server, in order to avoid the coolant liquid to meet the high temperature in the second server and appear condensing, perhaps produce vapor, cause causing to destroy server 2 subassembly.

Preferably, in one embodiment, the control module is further capable of controlling the flow rate of the coolant flowing into the water inlet of the first server by controlling the opening degree of the first waterway switching element 6, thereby effectively controlling the temperature of the coolant entering the water inlet of the second server.

Illustratively, when the temperature of the cooling liquid at the water inlet of the second server is lower, the control module can increase the opening of the water diversion pipe 5 at the water outlet of the first server, so that more cooling liquid flows into the first server, and when the temperature of the cooling liquid at the water inlet of the second server is relatively higher, the control module can decrease the opening of the water diversion pipe 5 at the water outlet of the first server, so that less cooling liquid flows into the second server, thereby achieving the effect of neutralizing the cooling liquid at the water inlet of the second server.

With this arrangement, when the heat dissipating member 201 does not operate or is not fully loaded, and the third temperature measuring element 208 detects that the temperature of the corresponding heat dissipating member 201 is low, the control module can control the second waterway switching element 207 to switch to the fourth state, so that the cooling liquid does not need to flow into the heat dissipating branch line 203 corresponding to the heat dissipating member 201, and the fan 13 in the server 2 dissipates heat from the heat dissipating member 201. When the third temperature measuring element 208 detects that the temperature of the corresponding heat dissipating component 201 is higher, the control module can control the second waterway switching element 207 to switch to the fifth state, so that the cooling liquid in the heat dissipating main pipeline 202 can flow into the heat dissipating component 201 through the corresponding heat dissipating branch pipeline 203, and dissipate heat of the heat dissipating component 201. Therefore, the server cabinet provided by the embodiment of the application can accurately radiate the heat radiating component 201, so that the cooling liquid is reasonably applied.

In addition, in the embodiment of the present application, the third temperature measuring element 208 is installed in the heat dissipation component 201, so that the control module of the server cabinet can receive the real-time temperature of each heat dissipation component 201, and determine whether the component is abnormal by monitoring the temperature and the carrying state of the heat dissipation component 201. Specifically, the control module can determine whether an abnormality has occurred in the component by monitoring the baseline and peak temperatures of the component, and the carrying conditions of the component. Can maintain in time.

In one embodiment, as shown in fig. 11, 12 and 13, the inner diameter of the heat radiation main pipe 202 is larger than the inner diameter of the heat radiation branch pipe 203, and the second waterway switching element 207 includes a second cover plate 2071 and a second rotation source 2072. The second cover 2071 is hinged at the connection part of the heat dissipation branch pipeline 203 and the heat dissipation main pipeline 202, and the diameter of the second cover 2071 is smaller than that of the heat dissipation main pipeline 202. The power output end of the second rotating source 2072 is connected to the second cover 2071 and can drive the second cover 2071 to rotate and switch between the fourth state and the fifth state.

By so doing, when the second cover 2071 is located in the radiating branch line 203 by the drive of the second rotation source 2072, the second waterway switching element 207 is in the fourth state. Because the inner diameter of the main heat dissipation pipeline 202 is larger than the inner diameter of the branch heat dissipation pipeline 203, when the second cover plate 2071 is driven by the second rotation source 2072 to be positioned in the main heat dissipation pipeline 202, the second cover plate 2071 cannot completely block the main heat dissipation pipeline 202, so that part of the cooling liquid in the main heat dissipation pipeline 202 can flow into the branch heat dissipation pipeline 203, and the rest of the cooling liquid can continue to flow along the main heat dissipation pipeline 202, so that the main heat dissipation pipeline 202 is not influenced to provide the cooling liquid for the subsequent branch heat dissipation pipeline 203.
