Description

Technical Field

[0001] The invention relates to the technical field of computer servers, and in particular to a computer server chassis based on liquid cooling and heat dissipation. Background Art

[0002] A computer server is a high-performance computer device that provides various services to other computers (clients) in the network. These services include but are not limited to data storage, file sharing, email processing, web services, database management and many other functions. Compared with ordinary personal computers, servers usually have more powerful performance, including faster processors, more memory, larger storage capacity and higher network bandwidth, so that they can handle requests from multiple clients at the same time. However, computer servers will generate a lot of heat during operation, so they need to be cooled to ensure their normal operation.

[0003] In the prior art, most of the heat dissipation devices in the servo chassis only perform simple liquid cooling treatment on the CPU or GPU of the computer server, which is referred to as water cooling. However, because the power of the computer server is relatively large, if the temperature of the internal components is high, the life of the radiator in the water cooling will be shortened during continuous circulation, and the heat dissipation efficiency will also be reduced. When the water temperature is high, the temperature difference between the water temperature in the radiator and the surrounding air may decrease. In addition, the existing high-power water cooling will also consume a lot of electricity, and when the external temperature is low, the water temperature after heat dissipation is too low, which will cause condensation water to be generated on the electronic components. When the cold water enters the water pipe and contacts the high-temperature heating components, the surrounding water vapor will be cooled and liquefied, forming condensation water on the surface of the water pipe or the heating components. If the condensation water drips onto the motherboard and other electronic components, it may cause a short circuit, thereby affecting the normal operation of the computer server. Summary of the invention

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] 1. In the present application, by setting the first mounting shell, when the first temperature detector detects that the water temperature inside the first inner shell is below 70 degrees, the device can simply dissipate heat for the computer server, and when the first temperature detector detects that the water temperature inside the first inner shell is above 70 degrees, the water flow can be introduced into the water retention chamber. On the one hand, the water flow is mixed with the cold water originally existing in the water retention chamber to reduce the temperature of the water flow. On the other hand, the mixed water flow can be dissipated by the stirring blades, the first fins and the second fan to reduce its temperature. In this way, high-temperature water can be effectively prevented from directly entering the radiator, which greatly improves the heat dissipation efficiency and increases the life of the radiator without wasting much electric energy.

[0019] 2. In the present application, by setting up the second mounting shell, the water entering the second mounting shell can be cooled for a second time, and when the second temperature detector detects that the temperature of the water flowing out of the radiator is low, the second motor and the electric telescopic rod are started at the same time to wind the thermal insulation film and recycle the folding window, so that the second fins transfer the heat absorbed from the computer server through the second inner shell to the water-passing aluminum tube to simply heat it up and prevent the occurrence of condensed water, thereby ensuring the stable operation of the computer server.

[0020] In summary, the above-mentioned structural setting in the present application can, on the one hand, not only fully dissipate the heat of the computer server while avoiding the shortening of the radiator life, but also prevent the condensed water generated during the heat dissipation process from dripping onto electronic components such as the motherboard, causing a short circuit in the electronic components and affecting the normal operation of the computer server.

The connecting shaft 29 is rotatably mounted on the inner walls of the upper and lower sides of the second installation shell 20. A second motor 28 for driving the connecting shaft 29 to rotate is fixedly mounted on the second installation shell 20. A heat insulation film 30 is rolled up on the outer side of the connecting shaft 29. A ventilation groove is provided on the inner top wall of the second installation shell 20 at one end of the water-passing aluminum tube 22. A folding window 27 is slidably mounted in the ventilation groove. One side of the folding window 27 near the connecting shaft 29 is provided with a ventilation groove. The end is fixedly connected with a connecting block 26, and a telescopic groove 23 is opened on the upper inner part of the second mounting shell 20 located on one side of the radiator 4. An electric telescopic rod 24 is fixedly installed in the telescopic groove 23, and a pushing block 25 is fixedly installed at the telescopic end of the electric telescopic rod 24. The pushing block 25 is fixedly connected to the connecting block 26, and the lower end of the pushing block 25 is connected to the upper end of the insulation film 30. The folding window 27, the insulation film 30, the connecting block 26 and the pushing block 25 are all located between the second fin 33 and the outer side wall of the second inner shell 21.

[0037] The specific working principle of the present invention is as follows: first, the computer server is installed into the chassis 1, the redundant wires are arranged through the wire board 2, and the power is connected from the right side of the chassis 1. At this time, the cold end of the first water pump 9 is fitted to the surface of the CPU, and then the first water pump 9 is fixed to the mainboard through threaded connection. When the computer server is working, the CPU works and generates heat. At this time, the first water pump 9 works and starts water circulation, so that the water after the CPU absorbs heat enters the water pipe 7 through the telescopic tube 8. The telescopic tube 8 is installed on both sides of the first water pump 9. When hot water enters the water pipe 7, it will be introduced into the first water inlet 6.

[0038] At this time, there are two situations. The first situation is that when the first temperature detector 31 detects that the water temperature inside the first inner shell 10 is below 70 degrees, the device operates unchanged, and the hot water directly enters the water inlet 15 through the first inner shell 10, and then enters the radiator 4, and then is cooled by the first fan 5, so as to cool the hot water inside the radiator 4. The radiator 4 and the first fan 5 are installed on the first mounting shell 3 and the second mounting shell 20.

[0039] In the second case, when the power consumption of the computer server is high and the CPU is overheated, when the first temperature detector 31 detects that the temperature of the water inside the first inner shell 10 is above 70 degrees, the electric rotating shaft 13 will rotate, thereby driving the closed door 14 to rotate. The closed door 14 of the first inner shell 10 will rotate toward the center line of the first inner shell 10, so that the tops of the closed doors 14 fit together to form a sharp angle to guide the water flow. At this time, the hot water will flow to the water retention chamber 1102 due to the guidance of the closed door 14, and the water retention chamber 1102 is cold water. When entering, the first motor 1101 is started, driving the stirring blade 12 to rotate, thereby stirring the hot water and cold water inside the water retention chamber 1102 to mix them and cool the hot water. At this time, the second fan 18 installed on the upper cover 16 is started, and a first fin 17 is arranged inside it, which is used to absorb heat from the hot water in the water retention chamber 1102, and then the second fan 18 dissipates heat to the first fin 17, so that the temperature inside the water retention chamber 1102 is reduced. When the power usage decreases, the CPU temperature drops, and the hot water temperature drops, and the closed door 14 is closed.

[0040] In this way, the high-temperature hot water can be cooled to prevent it from directly entering the radiator 4, which greatly improves the heat dissipation efficiency and increases the life of the radiator 4 without wasting much electric energy.

[0041] The hot water after heat dissipation passes through the water pipe 7 and the second water pump 19, and enters the radiator 4 in the second installation shell 20 for secondary heat dissipation, so that the hot water dissipates heat more evenly, so that it can absorb heat better. After passing through the radiator 4 in the second installation shell 20, it will pass through the water-passing aluminum tube 22. At this time, there are two situations. The first situation is that when the second temperature detector 32 detects that the water temperature of the cold water is normal, it is directly output to the telescopic tube 8 through the water-passing aluminum tube 22, and the first water pump 9 circulates water to cool it down.

[0042] The second situation is that when the second temperature detector 32 detects that the temperature of the water flowing out of the radiator 4 is low, the electric telescopic rod 24 inside the second mounting shell 20 is retracted in the telescopic slot 23, driving the push block 25 to be recovered, and the second motor 28 fixedly connected to the lower end of the second mounting shell 20 is started, driving the connecting shaft 29 to rotate, so that the heat insulation film 30 is wound, and the recovery and winding of the push block 25 are carried out at the same time, and the lower end of the push block 25 is fixedly connected to the heat insulation film 30, and the front section of the push block 25 is fixedly connected to the connecting block 26, and the connecting block 26 is fixedly connected to the folding window 27, and the heat insulation film 30 is wound at the same time. When recycling is carried out, the folding window 27 will be driven to close, because the second fin 33 is arranged on the rear side of the second inner shell 21, and the position of the second fin 33 is facing the position of the GPU to absorb heat. When the insulation film 30 is not wound, the heat of the second fin 33 is insulated so that the heat is dissipated from the window at the folding window 27. At this time, the folding window 27 is closed, and the heat is indirectly dissipated to the water-passing aluminum tube 22, so that it is simply heated up to prevent condensation. When the water temperature is normal, the push block 25 drives the insulation film 30 to unfold and insulate again, thereby pushing the folding window 27 to open.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
