Description

Technical Field

[0002] The server is a data processing center that performs operations such as storage, retrieval, analysis, and statistics on data. It is widely used in the Internet, office, scientific research, finance, education and other fields. The number and performance of servers directly affect the speed and efficiency of data processing. With the development of computer technology, the power consumption and heat generation of servers continue to increase, which puts higher requirements on the heat dissipation system. The heat dissipation system of the server mainly includes air cooling, liquid cooling, and gas cooling. In the existing technology, the liquid cooling system has high heat dissipation efficiency, but occupies a large area, is expensive, and has high requirements for the working environment. It is often used in data centers, which is not conducive to promotion and use; the air cooling system is easy to use and low in cost, but has low heat dissipation efficiency and is usually used in industrial servers.

[0003] Among them, the high temperature inside the server mainly comes from the dense layout of integrated circuits and the increase in high-power consumption components. With the advancement of technology, the heat dissipation demand of servers is increasing, and traditional heat dissipation methods can no longer meet the growing heat dissipation demand; in addition, when the server is working, fans and other heat dissipation devices will generate a lot of noise, which not only interferes with the environment of the computer room, but also poses a threat to the physical and mental health of maintenance personnel who work in the computer room for a long time.

[0004] In the prior art, air circulation is formed by placing an air inlet fan and an air outlet fan opposite to each other to improve the efficiency of heat dissipation and reduce noise. However, since the existing servers mainly rely on fans for air cooling and heat dissipation, the heat dissipation effect is poor, and the noise generated during the operation of the fans still exists, and the noise reduction effect is poor.

[0035] The technical solution of the present invention is applied to provide a server with a heat dissipation function, including a cabinet 10, a cooling box 20, a partition plate 30, a guide tube 40, a heat exchange device 50 and a vacuum device 60, wherein the cabinet 10 has a first accommodating chamber 11, a first heating element 12 is arranged in the first accommodating chamber 11, and a first avoidance hole is opened on the top surface of the first accommodating chamber 11; the cooling box 20 is arranged in the first accommodating chamber 11 and is arranged in close contact with the first heating element 12 to absorb the heat generated during the operation of the first heating element 12, the cooling box 20 has a second accommodating chamber 21, and a second avoidance hole is opened at a position of the second accommodating chamber 21 opposite to the first avoidance hole; the partition plate 30 is arranged in the second accommodating chamber 21, and the second accommodating chamber 21 is divided into a first sub-accommodating chamber 211 and a second sub-accommodating chamber 212 in a direction away from the first heating element 12, and a heat absorbent 213 is stored in the first sub-accommodating chamber 211; The first end of the flow guide tube 40 is arranged on the partition plate 30, and the first end of the flow guide tube 40 is an open end, so as to be connected with the first sub-accommodating chamber 211; the heat exchange device 50 is arranged on the cabinet 10, and the heat exchange device 50 has a heat exchange chamber 51, and a third avoidance hole is opened at a position of the heat exchange chamber 51 opposite to the first avoidance hole; the flow guide tube 40 passes through the second avoidance hole, the first avoidance hole, and the third avoidance hole in sequence and extends into the heat exchange chamber 51, and the first avoidance hole of the flow guide tube 40 is arranged at the first avoidance hole of the heat exchange chamber 51. The two ends are closed ends, so that the heat absorber 213 that absorbs heat and becomes gaseous can flow into the guide tube 40 located in the heat exchange chamber 51 and turn back into liquid heat absorber 213 through heat exchange, and flow back to the first sub-accommodating chamber 211 along the guide tube 40; the vacuum device 60 is arranged on the cabinet 10, and the vacuum end of the vacuum device 60 is connected to the first sub-accommodating chamber 211, so as to evacuate the first sub-accommodating chamber 211 into a vacuum state to reduce the boiling point of the heat absorber 213.

[0036] By evacuating the first sub-chamber 211 to a vacuum state, it is helpful to reduce the boiling point of the heat absorber 213 in the first sub-chamber 211, which is more conducive to the heat absorber 213 to form a gas after absorbing heat, and flow along the guide tube 40 to the guide tube 40 located in the heat exchange chamber 51 for heat exchange, thereby exchanging heat in the gaseous heat absorber 213 into liquid heat absorber 213, and then flow back to the first sub-chamber 211 along the guide tube 40 again, ensuring the heat absorption reliability of the first heating element 12, thereby ensuring that the first heating element 12 can operate within a suitable ambient temperature, ensuring the operating reliability of the first heating element 12, and in addition, because the heat dissipation device such as a fan that is prone to generate noise is not used for the heat dissipation of the first heating element 12 in the present application, it is ensured that the server of the present application will not generate noise due to the fan fanning during operation.

[0037] It should be noted that, in the present application, the first heating element 12 is a main control board, which generates a lot of heat during its operation, and the main control board is arranged on the support board 14 .

[0038] It should be noted that, in the present application, the cooling box 20 is slidably arranged along the guide tube 40 relative to the partition plate 30, so as to adjust the volumes of the first sub-accommodating chamber 211 and the second sub-accommodating chamber 212 during the process of evacuating the first sub-accommodating chamber 211. In this way, the overall balance of the air pressure is ensured during the process of evacuating the first sub-accommodating chamber 211.

[0039] like Figure 2 As shown, the server further includes an elastic member 70, a first end of which is connected to the top surface of the first accommodating cavity 11, and a second end of which is connected to the top surface of the cooling box 20, so as to provide the cooling box 20 with an elastic force toward the first heating element 12, so that the cooling box 20 always fits with the first heating element 12. In this way, the setting of the elastic member 70 ensures that the elastic member 70 can provide the cooling box 20 with an elastic force toward the first heating element 12, thereby ensuring that the cooling box 20 always fits with the first heating element 12, and further ensuring the reliability of the heat absorbent 213 in the cooling box 20 to absorb the heat generated during the operation of the first heating element 12.

[0040] Optionally, the elastic member 70 is a spring, and the spring is sleeved on the outer peripheral side of the heat insulating pipe section 41 of the flow guide pipe 40 .

[0041] like Figures 2 to 4 As shown, the server further includes a heat absorbing plate 80, which is disposed in the first sub-accommodating chamber 211, and the surface of the heat absorbing plate 80 facing the heat absorber 213 is wavy. Thus, by making the surface of the heat absorbing plate 80 facing the heat absorber 213 wavy, it is helpful to increase the contact area between the heat absorber 213 and the heat absorbing plate 80, thereby ensuring that the heat absorber 213 can absorb more heat on the heat absorbing plate 80.

[0042] Preferably, the heat absorbing plate 80 is made of copper with high thermal conductivity, and the heat absorbent 213 is a water-ethanol solution. The boiling point of the anhydrous ethanol solution is low and it can quickly become gaseous after absorbing heat.

[0043] like Figure 2As shown, the guide pipe 40 includes a heat-insulating pipe section 41 and a cooling pipe section 42, wherein the heat-insulating pipe section 41 is extended in a straight line, and the first end of the heat-insulating pipe section 41 is connected to the partition plate 30, the first end of the heat-insulating pipe section 41 is an open end for communicating with the first sub-accommodating chamber 211, and the second end of the heat-insulating pipe section 41 passes through the second avoidance hole, the first avoidance hole, and the third avoidance hole in sequence and extends into the heat exchange chamber 51; the cooling pipe section 42 is spirally arranged in the heat exchange chamber 51, and the first end of the cooling pipe section 42 is communicated with the second end of the heat-insulating pipe section 41, and the second end of the cooling pipe section 42 is a closed end to prevent the heat absorbent 213 from flowing into the heat exchange chamber 51. The heat exchange chamber 51 stores a cooling liquid 52, and the cooling liquid 52 is used to exchange heat with the cooling pipe section 42, and the cooling pipe section 42 is immersed in the cooling liquid 52. In this way, by setting the guide pipe 40 to a structural form including an insulating pipe section 41 and a cooling pipe section 42, the reliability of the insulating pipe section 41 in guiding the gaseous heat absorber 213 and the reliability of the cooling pipe section 42 in exchanging heat with the gaseous heat absorber 213 are ensured, the temperature of the coolant 52 in the heat exchange cavity 51 is relatively low, so that the temperature of the cooling pipe section 42 is relatively low, and when the gaseous heat absorber 213 flows into the cooling pipe section 42, it is quickly condensed into liquid and refluxes along the insulating pipe section 41 to the first sub-containing cavity 211.

[0044] Optionally, the insulating pipe section 41 has an insulating effect to prevent the external environment from affecting the gaseous heat absorber 213 in the insulating pipe section 41, and the cooling pipe section 42 is made of a material with good thermal conductivity to ensure the reliability of condensation of the gaseous heat absorber 213.

[0045] like Figure 2 , Figure 3 and Figure 5 As shown, there are multiple flow guide tubes 40, which are spaced apart on the partition plate 30; there are multiple first avoidance holes, which correspond one-to-one to the multiple flow guide tubes 40; there are multiple second avoidance holes, which correspond one-to-one to the multiple first avoidance holes; there are multiple third avoidance holes, which correspond one-to-one to the multiple first avoidance holes. In this way, it is ensured that the gaseous heat absorbent 213 can be guided and heat exchanged through the multiple flow guide tubes 40, which is conducive to improving the heat absorption reliability of the heat absorbent 213 to the first heating element 12.

[0046] It should be noted that, in the present application, the cooling box 20 slides along the multiple insulation pipe sections 41 , and under the action of the elastic member 70 , the lower surface of the cooling box 20 is always in contact with the first heating element 12 .

[0047] like Figure 3 and Figure 5As shown, an annular gap is formed between the outer circumference of the partition plate 30 and the wall of the second accommodating chamber 21, and at least one ring of sealing ring 90 is arranged in the annular gap. In this way, the arrangement of the sealing ring 90 plays a role in the sealing reliability of the first sub-accommodating chamber 211.

[0048] like Figure 2 and Figure 3 As shown, the vacuum device 60 includes a pressure sensor 61, an air duct 62, a pump structure 63, a solenoid valve 65, a control module 66 and a comparison module, wherein the pressure sensor 61 is arranged on the cavity wall of the first sub-accommodating cavity 211 and is located above the heat absorber 213, and the pressure sensor 61 is used to obtain the real-time pressure in the first sub-accommodating cavity 211; the first end of the air duct 62 is connected to the first sub-accommodating cavity 211 to form a vacuum end, and the second end of the air duct 62 is located outside the first sub-accommodating cavity 211; the pump structure 63 is arranged on the cabinet 10, and the pump structure 63 is connected to the second end of the air duct 62 through a transition hose 64; the solenoid valve 65 is arranged on the air duct 62 or the transition hose 64 to control the on-off between the suction end of the pump structure 63 and the first sub-accommodating cavity 211; the control module 6 6 is arranged on the cabinet 10, the control module 66 is connected to the pressure sensor 61 by signal, and the control module 66 is connected to the pump structure 63 and the electromagnetic valve 65 by control; the comparison module is arranged on the cabinet 10, the comparison module is connected to the pressure sensor 61 by signal, and is used to compare the real-time pressure obtained by the pressure sensor 61 with the preset pressure and obtain comparison information, and the comparison module is connected to the control module 66 by signal; the control module 66 controls the pump structure 63 and the electromagnetic valve 65 to operate at the same time according to the comparison information obtained by the comparison module; when the real-time pressure is greater than the preset pressure, the control module 66 controls the pump structure 63 and the electromagnetic valve 65 to operate at the same time, so as to evacuate the first sub-accommodating chamber 211 into a vacuum state; when the real-time pressure is equal to the preset pressure, the control module 66 controls the pump structure 63 and the electromagnetic valve 65 to stop operating at the same time. In this way, the vacuuming reliability of the vacuuming device 60 on the first sub-accommodating chamber 211 is ensured, thereby effectively reducing the boiling point of the heat absorbent 213.

[0049] It should be noted that, in the present application, after the first sub-containment chamber 211 is evacuated to a vacuum state, the heat absorber 213 absorbs heat and becomes gaseous, and the pressure on the first sub-containment chamber 211 is small and can be ignored.

[0050] like Figure 1 and Figure 2As shown, the server further includes a second heating element 100 and a third heating element 200. The heat generated during the operation of the second heating element 100 and the third heating element 200 is less than the heat generated during the operation of the first heating element 12. The second heating element 100 and the third heating element 200 are arranged at the bottom surface of the first accommodating chamber 11; wherein, a first ventilation hole 111 is provided at the cavity wall surface of the first accommodating chamber 11 opposite to the second heating element 100, and a first filter 112 is arranged at the first ventilation hole 111; a second ventilation hole 113 is provided at the cavity wall surface of the first accommodating chamber 11 opposite to the third heating element 200, and a second filter 114 is arranged at the second ventilation hole 113; the first ventilation hole 111 and the second ventilation hole 113 are respectively located on two opposite cavity walls of the first accommodating chamber 11. In this way, it is ensured that the air circulation of the first ventilation hole 111 and the second ventilation hole 113 is conducive to effectively cooling the second heating element 100 and the third heating element 200 by air cooling.

[0051] like Figure 1 and Figure 2 As shown, a plurality of universal wheels 300 are also provided at the bottom of the cabinet 10. The provision of the plurality of universal wheels 300 ensures the overall mobility of the server.

[0052] like Figure 1 As shown, the cabinet 10 is also provided with a viewing window 13, which is made of transparent tempered glass. Through the viewing window 13, it is easier to observe the working conditions inside the cabinet 10, that is, it allows the operation and maintenance personnel to directly observe the operating status of the internal components, such as the LED indicator light, fan speed, etc., without opening the server shell, which helps to quickly diagnose problems and improve the efficiency of troubleshooting and maintenance. The choice of tempered glass material ensures the impact resistance of the observation window, and it will not break even under accidental collision or pressure changes, ensuring the safety of the internal components of the server.
