[0002] With the increase of server power consumption, traditional air cooling has been difficult to meet the demand for efficient heat dissipation. In comparison, liquid cooling, especially water cooling technology, can achieve better heat exchange efficiency in a smaller space, but since water may have safety hazards when in contact with electronic components, most manufacturers will use oil-based liquids with high thermal conductivity to replace air or water to complete the task of heat transfer. This method not only improves cooling efficiency, but also reduces maintenance costs and risks.
[0003] In the process of using oil cooling, in order to ensure the cooling effect of oil cooling, most equipment will pass the cooling oil into the pipeline, and pass through the different aperture sizes of the orifice on the pipeline to make the cooling oil flow into the cooling box where the server box is placed. However, when a large amount of cooling oil is passed into the single-layer pipeline, the cooling oil cannot flow in the single-layer pipeline in time and will flow out of the pipeline into the cooling box through the adjacent orifice, so that the cooling oil in the cooling box cannot be uniformly filled, thereby affecting the cooling effect of the server case.

DETAILED DESCRIPTION
[0034] The following will be described in detail in combination with the accompanying drawings. Figures 1-9 The application is further described in detail.
[0035] Embodiment:
[0036] The embodiment of the application discloses a double-layer uniform-flow cooling oil cooling device, referring to Figure 1 and Figure 2 , comprising a foot stand 1, a cooling box 2 is installed on the foot stand 1, an oil passing assembly 3 for filling cooling oil into the cooling box 2 is installed on the foot stand 1, a flow guiding assembly 4 for controlling the flow of the cooling oil is installed in the cooling box 2, and an oil outlet assembly 5 for discharging the cooling oil is connected to the cooling box 2.
[0037] The server box is placed in the cooling box 2, the oil passing assembly 3 passes the cooling oil into the cooling box 2, the flow of the cooling oil is controlled through the flow guiding assembly 4, the cooling oil is uniformly filled in the cooling box 2, and the cooling oil can uniformly rise to cool the server box, so that the cooling effect of the cooling oil is improved, and the cooling oil is finally discharged by the oil outlet assembly 5, which is beneficial to improving the efficiency of heat dissipation and cooling of the double-layer uniform-flow cooling oil cooling device in the use process.
[0038] The oil passing assembly 3 comprises a main oil passing pipe 31, the main oil passing pipe 31 is fixedly installed on the foot stand 1, the main oil passing pipe 31 is arranged below the cooling box 2, and two or more than two branch oil passing pipes 32 are fixedly connected to the main oil passing pipe 31 at equal intervals.
[0039] The cooling oil is passed from the main oil passing pipe 31 and then filled in the cooling box 2 from multiple positions through the branch oil passing pipes 32, which is beneficial to improving the filling speed of the cooling oil in the cooling box 2.
[0040] Referring to Figure 3 , Figure 4 , Figure 5 and Figure 6The flow guide assembly 4 comprises a flow guide cover 41 fixedly installed at the bottom of the cooling box 2, the flow guide cover 41 is arranged along the length direction of the cooling box 2, the distance between the flow guide cover 41 and the two side walls in the width direction of the cooling box 2 is equal, a partition plate 42 is fixedly installed in the flow guide cover 41, the partition plate 42 equally divides the flow guide cover 41 into two layers in the up-down direction, the oil passage branch pipe 32 passes through the bottom of the cooling box 2 and is connected with the partition plate 42. Two or more liquid guide grooves 421 are arranged along the length direction of the partition plate 42, the liquid guide grooves 421 are arranged on both sides of the oil passage branch pipe 32 with the oil passage branch pipe 32 as the center, the liquid guide grooves 421 are long strip-shaped square grooves, the length of the liquid guide groove 421 close to the oil passage branch pipe 32 is the longest, and the length of the liquid guide groove 421 farther away from the oil passage branch pipe 32 is shortened in turn. The partition plate 42 is fixedly installed with a baffle 422, the baffle 422 is arranged below the partition plate 42, and the baffle 422 is arranged on the side of the liquid guide groove 421 away from the oil passage branch pipe 32. The side walls on both sides of the flow guide cover 41 are provided with first liquid outlet holes 411, the first liquid outlet holes 411 are located below the partition plate 42, the cooling box 2 is fixedly installed with a placing flat plate 43 for placing the server box body, the placing flat plate 43 is arranged above the flow guide cover 41, a gap is left between the placing flat plate 43 and the flow guide cover 41, and the placing flat plate 43 is provided with second liquid outlet holes 431.
[0041] The cooling oil enters the flow guide cover 41 from the oil passage branch pipe 32, and the cooling oil flows on the partition plate 42 first, and falls below the partition plate 42 when passing through the liquid guide groove 421 on the partition plate 42. Because the viscosity of the cooling oil is greater than that of water, when the cooling oil stays on the partition plate 42, it quickly flows to both ends of the partition plate 42, and the cooling oil has a tendency to flow to both sides of the partition plate 42. When passing through the liquid guide groove 421, most of the cooling oil flows to both ends of the partition plate 42 before falling from the liquid guide groove 421, which easily causes the cooling oil flow close to both ends of the partition plate 42 to be too large, increases the length of the liquid guide groove 421 close to the oil outlet position connected with the partition plate 42 and the oil passage branch pipe 32, and expands the cooling oil flow close to the oil passage branch pipe 32, so that the cooling oil can uniformly fall from each liquid guide groove 421 on the partition plate 42.
[0042] The cooling oil flows from above the partition plate 42 to below the partition plate 42, and then flows to both sides of the flow guide cover 41 through the first liquid outlet hole 411, so as to facilitate the cooling oil to fill in both sides of the cooling box 2 in the width direction. After the cooling oil flows into the cooling box 2 from the flow guide cover 41, the cooling oil uniformly rises to above the placing flat plate 43 through the second liquid outlet hole 431. The flow of the cooling oil is controlled by the flow guide assembly 4. The cooling oil first flows on the upper layer of the flow guide cover 41, and the partition plate 42 guides the cooling oil to both sides of the flow guide cover 41 in the length direction, so that the cooling oil can fall downward at the same time in the entire length direction of the cooling box 2, thereby ensuring that the first liquid outlet hole 411 below the partition plate 42 can uniformly flow out the cooling oil at the same time, ensuring that the cooling oil can quickly and uniformly fill in the cooling box 2, and ensuring that the liquid level of the cooling oil can uniformly rise. When the liquid level of the cooling oil stably rises to the server box, the liquid level of the cooling oil can absorb the heat on the server box from bottom to top. The stable and uniform rising of the cooling oil can realize the overall and uniform cooling of the server box, prevent the mixing of the relatively cold cooling oil and the relatively hot cooling oil due to the multi-directional flow of the cooling oil, and affect the cooling effect. The liquid level of the cooling oil stably rising can gradually and integrally absorb the heat on the server box and be discharged through the oil outlet assembly 5, which is beneficial to improve the cooling effect of the double-layer flow-equalizing cooling oil cooling device in the use process.
[0043] With reference to Figure 7 and Figure 8 , the flow guide cover 41 is provided with a flow slowing assembly 44. The flow slowing assembly 44 comprises a shielding block 441 fixedly installed on the flow guide cover 41. The shielding block 441 is arranged above the liquid guide groove 421. The shielding block 441 is provided with an inclined surface close to one side of the oil passage branch pipe 32. The shielding block 441 is fixedly installed with a flow slowing ball 442 on the bottom surface. The shielding block 441 is provided with an oil outlet 443.
[0044] After the cooling oil is filled in, when the oil level of the cooling oil reaches the height of the flow slowing ball 442, the cooling oil gushing out of the oil passage branch pipe 32 will contact the flow slowing ball 442. The flow slowing ball can slow down the speed of the gushing cooling oil, adjust the liquid level of the cooling oil, and make the cooling oil flow to both ends of the partition plate 42 at a gentle speed. When a large amount of cooling oil gushes into the liquid level above the partition plate 42 and continues to rise to contact the shielding block 441, the shielding block 441 guides the cooling oil through the inclined surface, so that part of the cooling oil can flow in the direction of the liquid guide groove 421, and part of the cooling oil continues to flow to both ends of the partition plate 42 through the oil outlet 443, which is beneficial to enhance the flow effect of the cooling oil in the flow guide cover 41.
[0045] With reference to Figure 9The oil outlet assembly 5 comprises an oil discharge tank 51 fixedly installed on the foot stand 1, a first buffer plate 52 and a second buffer plate 53 are installed in the oil discharge tank 51, the first buffer plate 52 is located above the second buffer plate 53, a first backflow hole 521 is formed in the first buffer plate 52, a second backflow hole 531 is formed in the second buffer plate 53, the oil discharge tank 51 is in communication with the cooling tank 2 at the portion above the first buffer plate 52, and a discharge pipe 54 is connected to the bottom of the oil discharge tank 51.
[0046] After the cooling oil absorbs the heat on the server, the cooling oil flows into the oil discharge tank 51, is buffered by the first buffer plate 52, falls onto the second buffer plate 53 from the first backflow hole 521, and then flows to the discharge pipe 54 from the second backflow hole 531 in the second buffer plate 53, so that the cooling oil can be quickly discharged from the cooling tank 2, and the cooling oil is prevented from staying in the cooling tank 2 after being heated to affect the heat dissipation effect.
[0047] The implementation principle of the embodiment of the application is that the server tank body is placed in the cooling tank 2, the oil feeding assembly 3 feeds the cooling oil into the cooling tank 2, the flow of the cooling oil is controlled by the flow guide assembly 4, the cooling oil is uniformly filled in the cooling tank 2, and the cooling oil can uniformly and stably rise to cool the server tank body, so that the cooling effect of the cooling oil is improved, and the cooling oil is finally discharged by the oil outlet assembly 5 after absorbing the heat on the server tank body, which is beneficial to improving the efficiency of the double-layer flow-equalizing cooling oil cooling device in the process of heat dissipation and cooling.
