DETAILED DESCRIPTION

[0043] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in combination with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0044] like Figures 1 to 7As shown, the spray-type liquid cooling server involved in this embodiment includes: a server housing 1. A supporting device 2 is provided inside the server housing 1, and a plurality of working components 3 are fixedly provided on the supporting device 2. The working components may include but are not limited to CPU, memory, hard disk, RAID card, network card, and the like. In order to be able to liquid-cool the working components, a waterproof cover may be provided on the working components, and the coolant may be sprayed onto the waterproof cover to cool the working components inside. A water discharge element may also be used to configure the working components so that the coolant is sprayed onto the working components for direct cooling. The specific method is not limited in the present utility model.

[0045] The server housing 1 of this embodiment is fixedly connected with a driving device 4; the driving device 4 can be a water pump, or other driving element that drives the coolant to flow. The supporting device 2 includes: a liquid collecting shell 21, a liquid storage chamber 23 is arranged inside the liquid collecting shell 21, and a liquid through hole 26 is opened on the top of the liquid collecting shell 21. The input end of the driving device 4 extends into the liquid storage chamber 23, which is based on the cooling of the coolant back to the liquid storage chamber 23, and after the cold and heat exchange inside the liquid storage chamber 23, it is driven by the driving device 4 to cool down the working element.

[0046] Exemplarily, a plurality of buffer mechanisms 24 are arranged inside the liquid storage chamber 23; a mounting filter plate 25 is fixedly connected to the top of the buffer mechanism 24; a plurality of working elements 3 are respectively mounted on the mounting filter plate 25; a plurality of filtrate holes are opened on the mounting filter plate 25, so that the coolant can flow back to the liquid storage chamber 23.

[0047] The output end of the driving device 4 is connected to a liquid guide tube 5; the liquid guide tube 5 is connected to a plurality of water distribution branches 6; the water distribution branches 6 extend into the interior of the server housing 1 and are arranged on the upper part of the working element 3; a spray device 7 is installed on the water distribution branch 6. Here, the liquid guide tube 5 can be arranged outside the server housing 1. In order to obtain the temperature information inside the server housing 1, a temperature sensor 9 is installed inside the server housing 1. The temperature sensor 9 can be connected to the BMC module of the server so that the BMC module can dynamically adjust the temperature. The BMC module of the server can also be connected to the driving device 4, and the coolant flow rate can be controlled by controlling the driving device 4, thereby adjusting the temperature.

[0048] When the spray-type liquid cooling server of this embodiment is in use, the temperature sensor 9 detects the temperature information inside the server housing 1, and the BMC module of the server controls the operation of the drive device 4 in combination with the temperature information. The drive device 4 draws out the insulating coolant in the liquid storage chamber 23 and transmits it to the water distribution branch pipe 6 through the liquid guide pipe 5, and then sprays it to the heating working element 3 through the spray device 7. With the cooperation of multiple spray devices 7, the working element 3 is fully in contact with the insulating coolant, so that the insulating coolant takes away the heat. The falling insulating coolant passes through the installation filter plate 25 and enters the liquid storage chamber 23 of the liquid collection shell 21. After the temperature of the insulating coolant in the liquid storage chamber 23 decreases, it cooperates with the drive device 4 to extract and spray again, thereby forming a circulation path, which is convenient for the continuous use of the insulating coolant.

[0049] This embodiment improves the cooling speed and cooling effect of the insulating coolant in the liquid storage chamber 23, and a heat dissipation support plate 22 is connected to the bottom of the liquid collection shell 21. A cooling device 8 is provided near the heat dissipation support plate 22.

[0050] Optionally, a cooling device 8 is provided near the heat dissipation support plate 22; the cooling device 8 is provided with a ventilation cavity 84, the first cavity wall of the ventilation cavity 84 is attached to the outer wall of the heat dissipation support plate 22, and a plurality of air outlet holes are opened on the first cavity wall; the second cavity wall arranged opposite to the first cavity wall is connected with a connecting pipe 83, the connecting pipe 83 is connected with a connecting shell 81, and a fan 82 is installed inside the connecting shell 81.

[0051] In this embodiment, the cooling device 8 and the heat dissipation support plate 22 can accelerate the cooling of the insulating coolant in the supporting device 2, so as to improve the heat dissipation efficiency of the device. Since the working element 3 is installed on the mounting filter plate 25, when the server housing 1 is subjected to external vibration, the impact of the working element 3 can be reduced under the action of the buffer mechanism 24, thereby achieving the protection effect and extending the service life of the working element 3 in the server housing 1.

[0052] As an embodiment of the present application, the buffer mechanism 24 includes: a support rod 241, the top end of the support rod 241 abuts against the lower surface of the filter plate 25, the bottom end of the support rod 241 is connected to a buffer connecting plate 242; the bottom of the buffer connecting plate 242 is connected to a first spring plate 243; the first spring plate 243 is cooperatively connected to a second spring plate 244; the bottom end of the first spring plate 243 and the bottom end of the second spring plate 244 are respectively connected to the inner bottom wall of the liquid storage chamber 23.

[0053] For example, the cross-sections of the first spring plate 243 and the second spring plate 244 are arc-shaped respectively; the arc top of the first spring plate 243 is abutted against the bottom of the buffer connecting plate 242; the arc top of the second spring plate 244 is abutted against the inner bottom wall of the liquid storage chamber 23. An elastic ring 245 is provided between the first spring plate 243 and the second spring plate 244.

[0054] It should be noted that the insulating coolant falling after spraying flows back into the liquid storage chamber 23 through the installation filter plate 25 and the liquid through hole 26 on the top of the liquid collecting shell 21. The heat dissipation support plate 22 is in a grid shape, and the heat dissipation support plate 22 can extend to the outside of the server housing 1. Since the heat dissipation support plate 22 has a large contact area with the outside, it can accelerate the dissipation of the heat absorbed by the insulating coolant in the liquid storage chamber 23, and can also provide support for the heat dissipation support plate 22 to the server housing 1, so that the bottom of the server housing 1 is suspended, which is more convenient for heat dissipation.

[0055] In this embodiment, when the server housing 1 is subjected to external vibration, the first spring plate 243 and the second spring plate 244 are deformed by force, so that part of the vibration is converted into elastic potential energy of the first spring plate 243 and the second spring plate 244 and reduced. At the same time, since the surfaces of the first spring plate 243 and the buffer connecting plate 242 are in the insulating coolant, part of the vibration is absorbed and weakened by the insulating coolant, thereby further achieving buffering, so that the impact transmitted to the working element 3 is greatly reduced, and the working element 3 is prevented from being damaged by vibration. Through the elastic ring 245, when the first spring plate 243 and the second spring plate 244 are deformed, the upper and lower sides of the elastic ring 245 are squeezed at the same time to cause deformation. At this time, the elastic force of the elastic ring 245 itself applies a reverse force to the first spring plate 243 and the second spring plate 244, which can prevent the first spring plate 243 and the second spring plate 244 from being excessively deformed, and play a protective role for the first spring plate 243 and the second spring plate 244.

[0056] As an embodiment of the present application, the spray device 7 is provided with a water outlet pipe 701, the top of which is connected to the water distribution branch pipe 6, a fixed sleeve 702 is provided on one side of the water outlet pipe 701, and a movable push plate 703 is slidably connected inside the fixed sleeve 702; the bottom end of the movable push plate 703 is connected to a first guide rod 705; the bottom end of the water outlet pipe 701 is truncated cone-shaped, and an opening is provided at the bottom end of the water outlet pipe 701, and a blocking ball 709 is provided at the opening; the blocking ball 709 is connected to a second guide rod 708, and the first guide rod 705 and the second guide rod 708 are connected by a U-shaped tube 707. A water splash plate 711 is installed on the second guide rod 708. The outer diameter of the blocking ball 709 is larger than the inner diameter of the opening of the water outlet pipe 701; a return spring 706 is sleeved on the outside of the first guide rod 705, and the top end of the return spring 706 is abutted against the bottom of the movable push plate 703; the bottom end of the return spring 706 abuts against the inner bottom wall of the fixed sleeve 702.

[0057] It can be seen that the temperature-sensitive fluid can be set through the cavity 704 in the spray device 7, and the fixed sleeve 702 is made of metal material with good thermal conductivity. When the temperature inside the server shell 1 rises, the heat is transferred to the temperature-sensitive fluid through the fixed sleeve 702, so that the temperature-sensitive fluid expands due to the heat, and the movable push plate 703 is pushed and moves downward along the inner surface of the fixed sleeve 702, and the first guide rod 705 moves downward accordingly, and the return spring 706 is compressed. The bottom of the first guide rod 705 squeezes the air column 710 inside the U-shaped tube 707, so that the air column 710 pushes the second guide rod 708, and the second guide rod 708 moves upward along the inner surface of the U-shaped tube 707, driving the blocking ball 709 moves upward, so that a gap is generated between the blocking ball 709 that originally blocked the output end of the water outlet pipe 701 and the output end of the water outlet pipe 701, and the insulating coolant is sprayed out through the gap. Under the obstruction of the splash plate 711, the range of the sprayed insulating coolant is increased, which is convenient for the insulating coolant to fully contact the working element 3, and the heat dissipation effect can be improved. Moreover, the more heat the working element 3 generates, the greater the expansion degree of the temperature-sensitive fluid, and the greater the distance the blocking ball 709 moves upward, thereby making the gap between the blocking ball 709 and the water outlet pipe 701 larger, and more insulating coolant is sprayed, so that the spray amount of the insulating coolant is automatically adjusted, thereby improving the practicability of the device.

[0058] When the working element 3 stops running and gradually cools down, the temperature-sensitive fluid cools and contracts, and its volume decreases. At this time, the elastic force of the return spring 706 can drive the movable push plate 703 to move upward. Under the action of the air pressure of the air column 710, the second guide rod 708 moves downward, driving the blocking ball 709 to block the output end of the water outlet pipe 701 again, stopping the spraying, and effectively using the spray device 7 to meet the cooling needs involved in this application.
