Description

Technical Field

[0001] The utility model belongs to the technical field of servers, and in particular relates to a server chassis. Background Art

[0002] The server chassis is a box structure specially designed to install and protect server hardware components. Server chassis are usually made of thicker steel plates (usually more than 1mm) to ensure durability and resistance to deformation. Server heat dissipation is usually air-cooled, that is, multiple cooling fans are set in the server chassis, and heat dissipation holes are set on the server chassis. However, when the ambient temperature is high, the heat dissipation effect of this heat dissipation method is average.

[0003] In addition, the current portable server case includes a server case body, a cover assembly is installed on both sides of the server case body, and the cover assembly is limited by a limit assembly; a receiving cavity is opened on both sides of the server case body. Four rectangularly distributed moving rollers are fixedly installed on the lower surface of the server case body, and brake pads are installed on the moving rollers.

[0004] The chassis is portable and movable by arranging brake casters at the bottom of the server chassis, and the heat dissipation holes of the chassis are opened at the top. However, when the server chassis needs to be fixed, the stability is insufficient only by the contact between the brake casters and the ground. When the server is repaired, the chassis is prone to move. In addition, the existing server chassis only relies on the heat dissipation holes to dissipate heat, and the heat dissipation capacity is limited, so that the heat in the server chassis cannot be dissipated outward in time, thereby causing the server to overheat and stop running. Utility Model Content

[0005] In view of the above-mentioned deficiencies in the prior art, the utility model provides a server chassis to solve the above-mentioned technical problems.

[0006] The utility model provides a server chassis, comprising:

[0007] A box body and a heat dissipation base, wherein the heat dissipation base is detachably connected to the bottom of the box body;

[0008] The top of the box is provided with a plurality of heat dissipation holes, the bottom of the box is provided with a vent, and a heat dissipation fan is provided at the vent;

[0009] A cooling water tank is arranged in the heat dissipation base, and the cooling water tank faces the vent.

[0010] In an optional embodiment, the heat dissipation base includes a fixed plate and multiple connecting plates, one side of the connecting plate is connected to the bottom of the box, and the other side of the connecting plate is connected to an edge of the fixed plate; universal brake casters are provided at the four corners of the fixed plate.

[0011] In an optional embodiment, the central area of ​​the fixed plate is a hollow area; the bottom of the box body is connected to a hydraulic rod, and the hydraulic rod passes through the hollow area to connect to the heat conducting plate outside the fixed plate; a cooling water tank is provided on the heat conducting plate; and the maximum length of the hydraulic rod is greater than the height of the connecting plate.

[0012] In an optional embodiment, a plurality of heat-conducting columns are provided on the cooling water tank.

[0013] In an optional embodiment, one end of the heat-conducting column is outside the cooling water tank, and the other end of the heat-conducting column is inside the cooling water tank.

[0014] In an optional embodiment, the top surface of the cooling water tank is in the shape of an arc with a high middle and low surroundings.

[0015] In an optional embodiment, a bottom plate is attached to the bottom surface of the heat conducting plate; the heat conducting plate and the hollow area have the same size, and the bottom plate has a larger area than the heat conducting plate.

[0016] In an optional embodiment, the outer wall of the cooling water tank is paved with a thermal insulation coating.

[0017] In an optional embodiment, a retaining ring is provided on the periphery of the cooling water tank, the retaining ring is fixedly connected to the heat conducting plate, and absorbent cloth is filled between the retaining ring and the cooling water tank.

[0018] In an optional embodiment, a cavity for accommodating an ice pack is provided at the bottom of the cooling water tank.

[0019] The beneficial effect of the utility model is that the server chassis provided by the utility model adopts a split design, a cooling water tank is arranged in the base, and a ventilation system is arranged at the top and bottom of the box body, so as to realize the combination of air cooling and water cooling, improve the heat dissipation efficiency, and occupy too much computer room space.

[0020] The box body, base and heat conducting plate enable the entire chassis to be conveniently moved to the required area through the universal brake casters when the server chassis is in use. When the server chassis needs to be fixed, the casters are fixed by the brakes of the universal brake casters, and the heat conducting plate and the bottom plate are driven down by the electric hydraulic rod until the bottom plate contacts the ground. At this time, the contact area between the chassis and the ground is increased through the bottom plate, thereby improving the stability of the chassis placement and preventing the chassis from offsetting and shaking during maintenance;

[0021] In addition, the lowering of the heat conduction plate makes the inside of the box connected with the outside world, and the heat dissipation fan is started to extract the hot air inside the box and blow it to the heat conduction column, and the heat is exchanged with the cooling water in the cooling water tank through the heat conduction column to cool down. At the same time, since the air temperature in the box is high and the temperature of the heat conduction column is low due to the cooling water in the cooling water tank, the moisture in the hot air in the box will condense, and the moisture in the box will condense on the heat conduction column, and the condensed water will be introduced into the absorbent cloth through the arc on the top of the cooling water tank for absorption, thereby ensuring the dryness of the air in the box.

[0022] In addition, the utility model has a reliable design principle, a simple structure and a very broad application prospect. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0031] For details, please refer to Figure 1 , the server chassis includes:

[0032] The box body 1 and the heat dissipation base 3 are detachably connected to the bottom of the box body 1; the top of the box body 1 is provided with a plurality of heat dissipation holes, the bottom of the box body 1 is provided with a vent, and a heat dissipation fan 12 is provided at the vent; a cooling water tank 10 is provided in the base of the box body 1, and the cooling water tank 10 is directly opposite to the vent. The box body 1 is provided with a box door 3.

[0033] The heat dissipation base 3 includes a fixing plate and a plurality of connecting plates, one side of the connecting plate is connected to the bottom of the box body 1, and the other side of the connecting plate is connected to an edge of the fixing plate; universal brake casters 4 are provided at the four corners of the fixing plate.

[0034] Please refer to Figure 2 and Figure 3 The central area of ​​the fixed plate is a hollow area; the bottom of the box body 1 is connected to a hydraulic rod 5, and the hydraulic rod 5 passes through the hollow area to connect to the heat conducting plate 7 outside the fixed plate; a cooling water tank 10 is provided on the heat conducting plate 7; the maximum length of the hydraulic rod 5 is greater than the height of the connecting plate.

[0035] The entire chassis can be conveniently moved to the required area through the universal brake caster 4. When the server chassis needs to be fixed, the caster is fixed by braking the universal brake caster 4, and the heat conduction plate 7 and the base plate 6 are driven down by the hydraulic rod 5 until the base plate 6 contacts the ground. At this time, the contact area between the chassis and the ground is increased by the base plate 6, thereby improving the stability of the chassis placement and preventing the chassis from offsetting and shaking during maintenance.

[0036] Please refer to Figure 4 , a plurality of heat-conducting columns 11 are provided on the cooling water tank 10. One end of the heat-conducting column 11 is outside the cooling water tank 10, and the other end of the heat-conducting column 11 is inside the cooling water tank 10. The top surface of the cooling water tank 10 is an arc shape with a high middle and low surroundings. The bottom surface of the heat-conducting plate 7 is attached to the bottom plate 6; the heat-conducting plate 7 is the same size as the hollow area, and the area of ​​the bottom plate 6 is larger than that of the heat-conducting plate 7. The outer wall of the cooling water tank 10 is paved with a thermal insulation coating. A retaining ring 8 is provided on the periphery of the cooling water tank 10, and the retaining ring 8 is fixedly connected to the heat-conducting plate 7, and an absorbent cloth 9 is filled between the retaining ring 8 and the cooling water tank 10.

[0037] The outer wall of the cooling water tank 10 is provided with a heat-insulating coating. The air temperature in the box 1 is high, and the temperature of the heat-conducting column 11 is low due to the cooling water in the cooling water tank 10, so that the moisture in the hot air in the box 1 will condense, and the moisture in the box will condense on the heat-conducting column 11. Through the arc at the top of the cooling water tank 10, the condensed water is introduced into the absorbent cloth 9 for absorption, ensuring the dryness of the air in the box 1. When the air environment is relatively humid, the absorbent cloth 9 can be replaced regularly to ensure the dryness of the chassis environment.

[0038] As for the cooling of the cooling water tank 10, it mainly relies on the heat dissipation of its own heat-conducting columns 11. Because the server chassis is mainly placed in the computer room, and the computer room is generally equipped with temperature and humidity control equipment such as air conditioners, and the cold air generated by the air conditioner sinks, the ambient temperature at the bottom of the chassis will be lower than the ambient temperature at the top, which will facilitate the natural heat dissipation of the cooling water in the cooling water tank 10. Due to the operation of the equipment in the box, the air temperature inside will inevitably be higher than the cooling water, ensuring the normal condensation.

[0039] When the server chassis is in use, the entire chassis can be conveniently moved to a required area through the universal brake caster 4. When the server chassis needs to be fixed, the caster is fixed by braking the universal brake caster 4, and the heat conducting plate 7 and the bottom plate 6 are driven down by the electric hydraulic rod 5 until the bottom plate 6 contacts the ground. At this time, the contact area between the chassis and the ground is increased by the bottom plate 6, thereby improving the stability of the chassis placement and preventing the chassis from being offset and shaking during maintenance;

[0040] In addition, the interior of the box 1 is connected with the outside by lowering the heat conducting plate 7, and the heat dissipation fan 12 is started to extract the hot air inside the box 1 and blow it to the heat conducting column 11, and the heat is exchanged with the cooling water in the cooling water tank 10 through the heat conducting column 11 to cool down. At the same time, since the air temperature in the box 1 is high, the temperature of the heat conducting column 11 is low due to the effect of the cooling water in the cooling water tank 10, so that the moisture in the hot air in the box 1 will condense, and the moisture in the box will condense on the heat conducting column 11, and the condensed water will be introduced into the absorbent cloth 9 through the arc at the top of the cooling water tank 10 to ensure the dryness of the air in the box 1.

[0041] Although the present invention is described in detail by referring to the accompanying drawings and in combination with the preferred embodiments, the present invention is not limited thereto. Without departing from the spirit and essence of the present invention, a person skilled in the art may make various equivalent modifications or substitutions to the embodiments of the present invention, and these modifications or substitutions shall be within the scope of the present invention. Any person skilled in the art who is familiar with the present technical field may easily think of changes or substitutions within the technical scope disclosed in the present invention, and these shall be within the scope of protection of the present invention.
