Description

Technical Field

[0001] This application relates to the technical field of heat dissipation and cooling equipment, and particularly to a cooling device for evenly inputting coolant. Background Art

[0002] With the increase in the power consumption of servers, traditional air cooling has been difficult to meet the demand for efficient heat dissipation. In contrast, liquid cooling, especially water cooling technology, can achieve better heat exchange efficiency in a smaller space. However, since there may be potential safety hazards when water comes into contact with electronic components, most manufacturers will use an oily liquid with high thermal conductivity to replace air or water to complete the task of heat energy transfer. This method not only improves the cooling efficiency but also reduces the maintenance cost and risk.

[0003] During the use of oil cooling, in order to ensure the cooling effect of oil cooling, most devices will pass the cooling oil into the pipeline and fill it into the chassis through multiple identical pipelines. However, compared with cooling water, cooling oil is more viscous than cooling water. When the cooling oil flows, it will quickly fill the pipeline, and the flow rate of the cooling oil in the pipeline farther away from the oil inlet will be larger, resulting in uneven filling of the cooling oil in the chassis, thus affecting the cooling effect of the server chassis. Summary of the Invention

[0004] In order to improve the convenience of the cooling device for evenly inputting coolant during operation, this application provides a cooling device for evenly inputting coolant.

[0005] This application provides a cooling device for evenly inputting coolant, adopting the following technical solution: A cooling device for evenly inputting coolant includes a chassis, an input component for introducing coolant is connected to the chassis. The input component includes an input main pipe, and two or more input branch pipes are connected to the input main pipe. The input branch pipes are communicated with the chassis. The aperture of the input branch pipes gradually decreases in the oil inlet direction of the input main pipe. A flow equalizing component for controlling the flow of coolant is installed in the chassis. The flow equalizing component includes a flow equalizing cover, the flow equalizing cover is connected to the chassis, a diversion plate is installed in the flow equalizing cover, the diversion plate divides the flow equalizing cover into upper and lower layers, a liquid dropping groove is formed on the diversion plate, flow equalizing holes are formed on the side walls on both sides of the flow equalizing cover, and a discharge component for discharging cooling oil is connected to the chassis.

[0006] By adopting the above technical solution, the cooling oil is introduced into the oil delivery assembly, and the oil delivery assembly sends the cooling oil into the chassis. The aperture of the input branch pipe is gradually reduced in the oil inlet direction of the input main pipe, so as to ensure that the oil output at the connection position between the input branch pipe and the chassis is the same, enabling the cooling oil to evenly fill each part of the chassis. The cooling oil first flows on the diversion plate of the flow equalizing cover, and the diversion plate first diverts the cooling oil to both sides in the length direction of the chassis, enabling the cooling oil to first fill in the length direction of the chassis. During the diversion process of the diversion plate, when the cooling oil passes through the liquid dropping groove, it will drop below the diversion plate, controlling the flow of the cooling oil and evenly dispersing the cooling oil in the length direction of the chassis. After the cooling oil falls below the diversion plate, it will flow in the width direction of the chassis through the flow equalizing holes, enabling the cooling oil to evenly fill both sides of the flow equalizing cover. The diversion plate first controls the flow direction of the cooling oil to disperse the coolant and enhances the dispersion effect of the coolant, and then fills the coolant in the chassis through the flow equalizing holes, enabling the cooling oil to quickly and efficiently fill the chassis. When the coolant absorbs the heat of the server box body, the discharge assembly then discharges the cooling oil from the chassis, which is beneficial to improving the cooling efficiency of the cooling device for evenly inputting the coolant during use.

[0007] In a specific feasible implementation, three partition plates are installed on the chassis. The three partition plates are arranged at equal intervals and divide the chassis into four parts. The liquid dropping groove is a long strip-shaped square groove, and the length of the liquid dropping groove gradually decreases from the central position of each part to both ends of the diversion plate.

[0008] By adopting the above technical solution, because the viscosity of the cooling oil is greater than that of water, when the cooling oil flows on the diversion plate, a large amount of cooling oil will flow away from the central position on both sides of the liquid dropping groove. In order to prevent the coolant flow rate at the position far from the central position on the diversion plate from being too large, the length of the liquid dropping groove at the position far from the central position is reduced to ensure that the cooling oil can evenly fall from the diversion plate.

[0009] In a specific feasible implementation, the flow equalizing assembly further includes a fixed flat plate for placing the server box body. The fixed flat plate is installed on the chassis. The fixed flat plate is located above the flow equalizing cover and there is a gap between the fixed flat plate and the flow equalizing cover. The fixed flat plate is provided with liquid outlet holes.

[0010] By adopting the above technical solution, the server box body is placed on the fixed flat plate. When the cooling oil fills the chassis, it will flow above the fixed flat plate through the liquid outlet holes, and the evenly rising cooling oil will absorb the heat on the server box body, facilitating the rapid cooling of the server box body.

[0011] In a specific feasible implementation, a diversion component for enhancing the flow effect of the coolant is installed on the drainage plate. The diversion component includes a first mounting platform, on which a lifting rod is slidably connected. A lifting plate is connected to the lifting rod, and the lifting plate is arranged directly above the position where the input component feeds the coolant into the chassis.

[0012] By adopting the above technical solution, when the cooling oil is first introduced into the chassis or the flow rate of the cooling oil is increased, the cooling oil surges from the first input branch pipe onto the drainage plate. When the oil volume is too large, the cooling oil will impact on the lifting plate, facilitating the flow of the cooling oil to both sides in the length direction of the drainage plate.

[0013] In a specific feasible implementation, a second mounting platform is installed on the drainage plate. A sliding rod is slidably connected to the second mounting platform. A movable disk is connected to the sliding rod. A spring is sleeved on the sliding rod, with one end connected to the movable disk and the other end connected to the second mounting platform. A push rod is connected to the lifting rod, and the end of the push rod close to the movable disk abuts against the movable disk. The surface of the movable disk in contact with the push rod is set as an arc surface. A guide rail is fixedly installed on the drainage plate, and a slider is slidably installed on the guide rail. An adjusting rod is installed on the slider. A connecting rod is connected to the movable disk, and the connecting rod is connected to the slider. A guiding plate is rotatably installed on the adjusting plate, and a chute is formed on the guiding plate. A support rod is installed on the drainage plate, and a sliding strip is installed on the support rod. The sliding strip is slidably connected to the guiding plate through the chute.

[0014] By adopting the above technical solution, when the flow rate of the cooling oil increases, the rising of the lifting plate will cause the inclination angle of the guiding plate to increase. When the cooling oil flows onto the guiding plate, the guiding plate will guide the cooling oil towards the central position of the drainage plate, thereby facilitating the flow of the cooling oil from the liquid dropping groove position to the lower part of the drainage plate, accelerating the circulation of the cooling oil, and being beneficial to enhancing the circulation performance of the cooling oil during the flowing process.

[0015] In a specific feasible implementation, the lifting plate is set as an A-shaped folding plate.

[0016] By adopting the above technical solution, the A-shaped setting of the lifting plate facilitates the rapid flow of the cooling oil to both sides in the length direction of the drainage plate.

[0017] In a specific feasible implementation, the input component includes an input main pipe, which is installed on the support frame. A first input branch pipe, a second input branch pipe, a third input branch pipe, and a fourth input branch pipe are installed on the input main pipe. The first input branch pipe, the second input branch pipe, the third input branch pipe, and the fourth input branch pipe are respectively communicated with the chassis.

[0018] By adopting the above technical solution, after the cooling oil is introduced into the input main pipe, it is divided by four input branch pipes, which facilitates the rapid filling of the cooling oil in the chassis.

[0019] In a specific feasible embodiment, the discharge assembly includes a liquid discharge tank, the liquid discharge tank is communicated with the chassis, and a discharge pipe is connected to the liquid discharge tank.

[0020] By adopting the above technical solution, when the coolant absorbs the heat of the server box body, it will flow into the liquid discharge tank and be discharged by the discharge pipe, quickly discharging the coolant to prevent the coolant from remaining in the chassis and affecting the cooling effect.

[0021] In a specific feasible embodiment, a first buffer plate is installed in the liquid discharge tank. The liquid discharge tank above the first buffer plate is communicated with the chassis, and a first return hole is opened on the first buffer plate.

[0022] By adopting the above technical solution, when the coolant flows, it will fall on the first buffer plate and the second buffer plate, and be buffered by the first buffer plate and the second buffer plate to prevent the height of the coolant flow from being too large and mixing with air to generate bubbles in the cooling oil, affecting the subsequent cooling effect.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. The cooling oil is introduced into the oil delivery assembly, and the oil delivery assembly sends the cooling oil into the chassis. The cooling oil first flows on the diversion plate of the flow equalizing cover, and the diversion plate first diverts the cooling oil to both sides in the length direction of the chassis, so that the cooling oil can first fill in the length direction of the chassis. During the diversion process of the diversion plate, when the cooling oil passes through the liquid dropping groove, it will fall below the diversion plate, controlling the flow of the cooling oil and evenly dispersing the cooling oil in the length direction of the chassis. After the cooling oil falls below the diversion plate, it will flow in the width direction of the chassis through the flow equalizing holes, so that the cooling oil evenly fills both sides of the flow equalizing cover. The diversion plate first controls the flow direction of the cooling oil to disperse the coolant, enhancing the dispersion effect of the coolant, and then filling the coolant in the chassis through the flow equalizing holes, enabling the cooling oil to quickly and efficiently fill in the chassis. When the coolant absorbs the heat of the server box body, the discharge assembly then discharges the cooling oil from the chassis, which is beneficial to improving the cooling efficiency of the cooling device for evenly inputting the coolant during use.

[0024] 2. Through the setting of the diversion assembly, when the flow rate of the cooling oil increases, the lifting of the lifting plate will cause the inclination angle of the guide plate to increase. When the cooling oil flows onto the guide plate, the guide plate will guide the cooling oil to the central position of the diversion plate, thus facilitating the flow of the cooling oil from the position of the liquid dropping groove to below the diversion plate, accelerating the circulation of the cooling oil, and being beneficial to enhancing the circulation performance of the cooling oil during the flow process.

Detailed implementation manners

[0036] The following will further elaborate on this application in conjunction with the appended Figures 1-10 drawings.

[0037] Embodiment: An embodiment of this application discloses a cooling device for evenly inputting coolant. Referring to Figure 1 and Figure 2 , it includes a support frame 1, on which a chassis 2 is fixedly installed. An input component 3 for introducing cooling oil into the chassis 2 is installed on the support frame 1. A flow equalizing component 4 for controlling the flow of the cooling oil is installed inside the chassis 2. A discharge component 5 for discharging oil is connected to the chassis 2.

[0038] Place the server cabinet inside the chassis 2. The input component 3 pipes the cooling oil into the chassis 2. The flow of the cooling oil is controlled by the flow equalizing component 4, so that the cooling oil is evenly filled in the chassis 2. At the same time, it is ensured that the cooling oil can rise at a uniform speed to cool the server cabinet, improving the cooling effect of the cooling oil. After the cooling oil absorbs the heat on the server cabinet, it is finally discharged by the discharge component 5, which is beneficial to improving the efficiency of heat dissipation and cooling of the cooling device for evenly inputting coolant during use.

[0039] The input component 3 includes an input main pipe 31, which is fixedly installed on the support frame 1. The input main pipe 31 is arranged below the chassis 2. Two or more input branch pipes are fixedly connected to the input main pipe 31 at equal intervals. In this embodiment, the input branch pipes include a first input branch pipe 32, a second input branch pipe 33, a third input branch pipe 34, and a fourth input branch pipe 35. The first input branch pipe 32, the second input branch pipe 33, the third input branch pipe 34, and the fourth input branch pipe 35 are sequentially arranged close to the oil inlet of the input main pipe 31. Three partition plates 21 are fixedly installed inside the chassis 2. The three partition plates 21 are arranged at equal intervals to divide the chassis 2 into four parts. The first input branch pipe 32, the second input branch pipe 33, the third input branch pipe 34, and the fourth input branch pipe 35 are respectively communicated with the four parts of the chassis 2, and the communication positions respectively connected to the four parts of the chassis 2 are located in the exact middle of each part. The aperture of the first input branch pipe 32 is larger than that of the second input branch pipe 33. The aperture of the second input branch pipe 33 is larger than that of the third input branch pipe 34. The aperture of the third input branch pipe 34 is larger than that of the fourth input branch pipe 35.

[0040] Cooling oil is introduced through the input main pipe 31, and then through the first input branch pipe 32, the second input branch pipe 33, the third input branch pipe 34, and the fourth input branch pipe 35, cooling oil is introduced into four parts of the chassis 2 respectively, so that the cooling oil enters the chassis 2 from four positions simultaneously, which is convenient for the cooling oil to quickly fill the chassis 2. Because the coolant used is cooling oil, which is different from cooling water, the viscosity of the cooling oil is large. When the cooling oil is transported through the input main pipe 31, the cooling oil will preferentially fill the pipeline of the input main pipe 31 and fill to one end far from the oil inlet of the input main pipe 31. Therefore, the pressure at the end far from the oil inlet of the input main pipe 31 will increase. In order to make the four feed pipes relatively uniform, the aperture of the first input branch pipe 32 is set to be smaller than that of the second input branch pipe 33, the aperture of the second input branch pipe 33 is set to be smaller than that of the third input branch pipe 34, and the aperture of the third input branch pipe 34 is set to be smaller than that of the fourth input branch pipe 35. The aperture of the input branch pipe gradually decreases in the oil inlet direction of the input main pipe 31, so as to ensure that the oil output at the connection positions of the first input branch pipe 32, the second input branch pipe 33, the third input branch pipe 34, and the fourth input branch pipe 35 with the chassis 2 is the same, so that the cooling oil can evenly fill each part of the chassis 2.

[0041] Refer to Figure 3 , Figure 4 and Figure 5 , the flow equalizing assembly 4 includes a flow equalizing cover 41, the flow equalizing cover 41 is fixedly installed at the bottom of the chassis 2, the flow equalizing cover 41 is arranged along the length direction of the chassis 2, and the distances between the flow equalizing cover 41 and the two side walls in the width direction of the chassis 2 are equal. A diversion plate 42 is fixedly installed in the flow equalizing cover 41, and the diversion plate 42 divides the flow equalizing cover 41 into two equal upper and lower layers. The first input branch pipe 32 passes through the bottom of the chassis 2 and is connected to the diversion plate 42. Figure 4 Only the connection relationship between the first input branch pipe 32 and the diversion plate 42 is shown. The second input branch pipe 33, the third input branch pipe 34, and the fourth input branch pipe 35 also pass through the bottom of the chassis 2 and are connected to the diversion plate 42. Because it does not affect the understanding of the solution, it is not shown. Liquid dropping grooves 421 are opened on both sides of the diversion plate 42 in the length direction with the first input branch pipe 32 as the center. The liquid dropping grooves 421 are long strip-shaped square grooves. The length of the liquid dropping groove 421 close to the first input branch pipe 32 is the longest, and the lengths of the liquid dropping grooves 421 farther away from the first input branch pipe 32 gradually shorten. A liquid blocking plate 422 is fixedly installed on the diversion plate 42, and the liquid blocking plate 422 is arranged on the side of the liquid dropping groove 421 far from the first input branch pipe 32. Flow equalizing holes 411 are opened on the side walls on both sides of the flow equalizing cover 41, and the flow equalizing holes 411 are located below the diversion plate 42. A fixed flat plate 43 for placing the server box body is fixedly installed on the chassis 2, the fixed flat plate 43 is arranged above the flow equalizing cover 41, and there is a gap between the fixed flat plate 43 and the flow equalizing cover 41. Liquid outlet holes 431 are opened on the fixed flat plate 43.

[0042] The cooling oil enters the flow equalizing cover 41 from the first input branch pipe 32. The cooling oil will first flow on the diversion plate 42 and fall below the diversion plate 42 when passing through the liquid dropping tank 421 on the diversion plate 42. After the cooling oil flows from above the diversion plate 42 to below the diversion plate 42, it then flows through the flow equalizing holes 411 to both sides of the flow equalizing cover 41, facilitating the cooling oil to fill both sides in the width direction of the chassis 2. After the cooling oil flows from the flow equalizing cover 41 into the chassis 2, it rises uniformly through the liquid outlet holes 431 to above the fixed flat plate 43. The flow of the cooling oil is controlled by the flow equalizing assembly 4. The cooling oil first flows on the upper layer of the flow equalizing cover 41, and the diversion plate 42 diverts the cooling oil to both sides in the length direction of the upper layer of the flow equalizing cover 41, enabling the cooling oil to fall simultaneously in the entire length direction of the chassis 2. As a result, the flow equalizing holes 411 below the diversion plate 42 can all flow out the cooling oil uniformly at the same time, ensuring that the cooling oil quickly and evenly fills the chassis 2 and ensuring that the liquid level of the cooling oil can rise uniformly. When the steadily rising liquid level of the cooling oil passes through the server cabinet, it will absorb the heat on the server cabinet from bottom to top. The stable and uniform rise of the cooling oil realizes the overall uniform heat dissipation of the server chassis, preventing the multi-directional flow of the cooling oil from causing the mixing of the colder cooling oil and the hotter cooling oil and affecting the cooling effect. The steadily rising liquid level of the cooling oil can gradually absorb the heat on the server chassis as a whole and be discharged through the discharge assembly 5, which is beneficial to improving the cooling effect of the cooling device with balanced input of the coolant during use.

[0043] Refer to Figure 6 , Figure 7 and Figure 8 , a diversion assembly 44 for enhancing the flow effect of the cooling oil is installed on the diversion plate 42. The diversion assembly 44 includes a first mounting table 441, the first mounting table 441 is fixedly installed on the diversion plate 42, a lifting rod 442 is slidably connected to the first mounting table 441, the lifting rod 442 is vertically arranged, a lifting plate 443 is fixedly installed on the lifting rod 442, the lifting plate 443 is arranged directly above the first input branch pipe 32, and the lifting plate 443 is set as an A-shaped folding plate. A second mounting table 444 is fixedly installed on the diversion plate 42, a sliding rod 4441 is slidably installed on the second mounting table 444, the sliding rod 4441 is horizontally arranged, a movable disk 445 is fixedly installed on the sliding rod 4441, a spring 4442 is sleeved on the sliding rod 4441, one end of the spring 4442 is fixedly connected to the movable disk 445, and the other end is fixedly connected to the second mounting table 444. A push rod 4421 is fixedly installed at the bottom end of the lifting rod 442, and one end of the push rod 4421 close to the movable disk 445 abuts against the movable disk 445. The surface of the movable disk 445 in contact with the push rod 4421 is set as an arc surface.

[0044] Refer to Figure 8 and Figure 9, a guide rail 446 is fixedly installed on the drainage plate 42, a slider 4461 is slidably installed on the guide rail 446, an adjusting rod 447 is fixedly installed on the slider 4461, the adjusting rod 447 is vertically arranged, a connecting rod 4451 is fixedly connected to the movable disk 445, the connecting rod 4451 is arranged below the adjusting rod 447, and the connecting rod 4451 is fixedly connected to the slider 4461. A guide plate 448 is rotatably installed on the adjusting rod 447, a chute 4481 is formed on the guide plate 448, a support rod 449 is fixedly installed on the drainage plate 42, the support rod 449 is arranged at one end of the guide plate 448 away from the adjusting rod 447, and a slide bar 4491 is fixedly installed on the support rod 449. The slide bar 4491 is slidably connected to the guide plate 448 through the chute 4481.

[0045] Referring to Figure 7 , Figure 8 and Figure 9 , when the cooling oil is first introduced into the chassis 2 or the flow rate of the introduced cooling oil is increased, the cooling oil surges onto the drainage plate 42 from the first input branch pipe 32. When the oil volume is too large, the cooling oil will impact on the lifting plate 443. The A-shaped setting of the lifting plate 443 facilitates the rapid flow of the cooling oil to both sides in the length direction of the drainage plate 42. When the flow rate of the cooling oil is large enough to lift the lifting plate 443, the lifting plate 443 drives the lifting rod 442 and the push rod 4421 to move upward. Through the action of the arc surface of the movable disk 445, the push rod 4421 pushes the movable disk 445 and the slide rod 4441 to slide closer to the guide rail 446 on the second installation platform 444. The movable disk 445 drives the connecting rod 4451 to move, the connecting rod 4451 drives the slider 4461 to slide on the guide rail 446, the slider 4461 pushes the guide plate 448 to move, and the guide plate 448 slides on the support rod 449 with the support rod 449 as the support point. When the end of the guide plate 448 connected to the adjusting rod 447 approaches the support rod 449, the guide plate 448 will rotate around the adjusting rod 447, thereby changing the inclination angle of the guide plate 448. When the flow rate of the cooling oil increases, the inclination angle of the guide plate 448 will increase. When the cooling oil flows onto the guide plate 448, the guide plate 448 will guide the cooling oil towards the central position of the drainage plate 42, thereby facilitating the cooling oil to flow from the position of the liquid dropping groove 421 to the lower part of the drainage plate 42, accelerating the flow of the cooling oil, and being beneficial to enhancing the flow performance of the cooling oil during the flowing process.

[0046] Referring to Figure 10 , the discharge assembly 5 includes a liquid discharge tank 51, the liquid discharge tank 51 is fixedly installed on the support frame 1, a first buffer plate 52 and a second buffer plate 53 are installed in the liquid discharge tank 51, the first buffer plate 52 is located above the second buffer plate 53, a first return hole 521 is formed on the first buffer plate 52, a second return hole 531 is formed on the second buffer plate 53, the part of the liquid discharge tank 51 above the first buffer plate 52 is communicated with the chassis 2, and a discharge pipe 54 is connected to the bottom of the liquid discharge tank 51.

[0047] After the cooling oil absorbs the heat on the server, it flows into the drain tank 51, is buffered by the first buffer plate 52, and then falls onto the second buffer plate 53 from the first return hole 521, and then flows to the discharge pipe 54 from the second return hole 531 on the second buffer plate, facilitating the rapid discharge of the cooling oil from the chassis 2 and preventing the cooling oil from staying in the chassis 2 after being heated, which affects the heat dissipation effect.

[0048] The implementation principle of the embodiment of the present application is as follows: The server box is placed in the chassis 2, the input component 3 transports the cooling oil into the chassis 2, and the flow of the cooling oil is controlled by the flow equalizing component 4, so that the cooling oil is evenly filled in the chassis 2.

When the cooling oil absorbs the heat on the server box, it is finally discharged by the discharge component 5, which is beneficial to improving the high efficiency of heat dissipation and cooling of the cooling device that evenly inputs the coolant during use.

[0049] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this.
