It discloses an anti-deformation electronic chip cooling liquid cooling plate, including the anti-deformation electronic chip cooling liquid cooling plate, which is composed of a shell, a cooling mechanism, a guide mechanism and a disassembly mechanism; the cooling mechanism is arranged on the inner side of the top of the shell, and is used to cool the electronic chip while avoiding the deformation of the heat dissipation fins caused by the change of temperature difference while achieving heat transfer; the guide mechanism is arranged on the inner side of the bottom of the shell, and is used to accelerate the outflow of liquid; the disassembly mechanism is arranged on the left and right sides of the cooling mechanism, and is used to replace the cooling mechanism. Although the design dissipates heat from the chip through the cooling mechanism, it still has the following defects: In this design, the refrigerant has to flow along the cooling mechanism for a period of time before reaching the top of the chip for cooling, but cannot directly reach the top of the chip for cooling, so the cooling effect of this design is not good.

[0006] To achieve the above objectives, the technical solution of the present invention is: A side-inlet and side-outlet end cover center slot drainage liquid cooling device, the device comprising an upper cover, a drainage channel and a bottom plate; One end of the upper cover is connected to a liquid inlet pipe of the drainage channel, and the other end of the drainage channel is a liquid outlet, and the liquid outlet faces the middle of the bottom plate, and a plurality of front shovel teeth are evenly distributed on the bottom plate at the front side of the liquid outlet, and the front shovel teeth are perpendicular to the liquid outlet, and a plurality of rear shovel teeth are evenly distributed on the bottom plate at the rear side of the liquid outlet, and the rear shovel teeth are perpendicular to the liquid outlet; The periphery of the bottom plate is connected to the periphery of the upper cover, and one end of the upper cover away from the liquid inlet pipe is connected to one end of the liquid outlet pipe.

[0008] A connecting plate is arranged on the bottom plate, and one end of the connecting plate close to the guide cavity matches the shape of the guide cavity.

[0010] There are two guide bars, which are symmetrically distributed along the center of the front shovel teeth and the rear shovel teeth; The connecting plate is provided with a guide hole, and one end of a guide bar is inserted into the guide hole.

[0011] A positioning block is arranged in the middle of a side of the bottom plate away from the upper cover, and a side of the positioning block away from the bottom plate is coated with thermal conductive silicone grease.

[0012] The height of the front shovel teeth is three to six millimeters, and the thickness of the front shovel teeth is 0.15 millimeters; the height of the rear shovel teeth is three to six millimeters, and the thickness of the rear shovel teeth is 0.15 millimeters.

[0013] The distance between the front shovel tooth and the nearest rear shovel tooth is two millimeters; the length of the front shovel tooth is twenty millimeters, and the length of the rear shovel tooth is twenty millimeters.

[0014] The liquid inlet pipe includes a refrigerant medium, and the flow rate of the refrigerant medium is 0.5 to 2.5 liters per minute; the pressure of the refrigerant medium in the liquid inlet pipe is greater than the pressure of the refrigerant medium in the liquid outlet pipe.

[0015] The refrigerant is 25% propylene glycol or 25% ethylene glycol.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In a side-inlet and side-outlet end cover center slot drainage liquid cooling device of the present invention, the device comprises an upper cover, a drainage channel and a bottom plate, the upper cover is provided with a drainage channel and a liquid outlet pipe, the drainage channel comprises a liquid inlet pipe and a liquid outlet, the opening direction of the liquid outlet is toward the middle of the bottom plate, and the bottom plate is also provided with a front shovel tooth and a rear shovel tooth. When in use, the refrigerant first enters the liquid inlet pipe, and then flows out from the liquid outlet, and then the refrigerant is flushed toward the middle of the bottom plate, at this time, the refrigerant takes away the heat in the middle of the bottom plate, thereby cooling the middle of the bottom plate, and then the refrigerant moves in the direction of the front shovel tooth or the rear shovel tooth, at this time, the refrigerant takes away the heat of the front shovel tooth or the rear shovel tooth, thereby cooling the bottom plate, and then the refrigerant flows to the liquid outlet pipe, and then the refrigerant leaves the device. The advantages of the present invention also include: First point: the chip is located on the bottom surface of the middle part of the bottom plate, and the liquid outlet is located above the middle part of the bottom plate. Therefore, the liquid outlet is aimed at the top of the chip, and the refrigerant flowing out of the liquid outlet will directly flush the middle part of the bottom plate, that is, the refrigerant can directly reach the top of the chip for cooling, so the cooling effect on the bottom plate is good; Second point: There are front shovel teeth and rear shovel teeth on the bottom plate, and both of them are in contact with the refrigerant, so the refrigerant can take away the heat from the front shovel teeth and the rear shovel teeth, thereby cooling the bottom plate; the front shovel teeth and the rear shovel teeth are densely distributed, and the area they occupy on the bottom plate is large, so the contact area with the refrigerant is large, so the refrigerant has a better cooling effect on the bottom plate, which improves the cooling effect of the bottom plate on the chip; Therefore, the present invention can directly reach above the chip to cool it down, and has a better cooling effect on the chip.

[0017] 2. In the side-inlet and side-outlet end cover center slot drainage liquid cooling device of the present invention, the end of the upper cover close to the liquid outlet pipe is a guide cavity, and the cross section of the guide cavity is triangular. When used, when the refrigerant moves to the guide cavity, the guide cavity guides the refrigerant to move toward the liquid outlet pipe, and the guide cavity can reduce the pressure difference between the liquid inlet pipe and the liquid outlet pipe to reduce the energy consumption when circulating the refrigerant. Therefore, the energy consumption of the present invention is relatively low.

[0018] 3. In the side-inlet and side-outlet end cover center slot drainage liquid cooling device of the present invention, two guide bars are also arranged on the upper cover, and the two guide bars are respectively located on both sides of the front shovel teeth and the rear shovel teeth. When used, the guide bars guide the refrigerant so that the refrigerant moves along the front shovel teeth or the rear shovel teeth, that is, the refrigerant moves along the prescribed route to ensure the cooling effect. Therefore, the guiding effect of the present invention is better.

[0019] 4. In the side-inlet and side-outlet end cover center slot drainage liquid cooling device of the present invention, a positioning block is provided at the bottom of the bottom plate, and thermal conductive silicone grease is coated on one surface of the positioning block. When used, the heat of the chip is transferred to the thermal conductive silicone grease, and the heat of the thermal conductive silicone grease is transferred to the positioning block. The positioning block transfers the heat to the bottom plate, and then the bottom plate is cooled by the refrigerant medium. The thermal conductive silicone grease has an extremely high thermal conductivity and can quickly conduct heat away from the chip to ensure the stability of the electrical performance of the chip. Therefore, the thermal conductive effect of the present invention is better.

[0020] 5. In the side-inlet and side-outlet end cover center slot drainage liquid cooling device of the present invention, the height of the front shovel teeth and the rear shovel teeth is 3 to 6 mm, the thickness is 0.15 mm, and the interval between the front shovel teeth and the rear shovel teeth is 2 mm. When used, the contact area between the front shovel teeth and the rear shovel teeth of the above size and the refrigerant is large, so the cooling effect is better. The interval between the front shovel teeth and the rear shovel teeth is 2 mm, so that the refrigerant in the liquid outlet has flow space, thereby having a better cooling effect on the middle of the bottom plate. Therefore, the cooling effect of the present invention is better.

[0021] 6. In a side-inlet and side-outlet end cover center slot drainage liquid cooling device of the present invention, the flow rate of the refrigerant is 0.5 to 2.5 liters per minute, the pressure of the refrigerant in the liquid inlet pipe is greater than the pressure of the refrigerant in the liquid outlet pipe, and the refrigerant is 25% propylene glycol or 25% ethylene glycol. When used, the flow rate of the refrigerant is 0.5 to 2.5 liters per minute, which can meet the actual use requirements of the device, that is, meet the actual heat dissipation requirements of the chip, and can prevent the chip from generating condensed water droplets on the surface due to excessive heat dissipation, which will affect the durability of the chip. Therefore, the present invention can prevent the generation of condensed water droplets. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] A connecting plate 33 is disposed on the bottom plate 3 , and one end of the connecting plate 33 close to the guide cavity 12 matches the shape of the guide cavity 12 .

[0055] The upper cover 1 is provided with a guide bar 13 , which is parallel to the front shovel teeth 31 and the rear shovel teeth 32 . The front end of the guide bar 13 exceeds the front end of the front shovel teeth 31 , and the rear end of the guide bar 13 exceeds the rear end of the rear shovel teeth 32 .

[0056] There are two guide bars 13, and the two guide bars 13 are symmetrically distributed along the center of the front shovel teeth 31 and the rear shovel teeth 32; The connecting plate 33 is provided with a guide hole 331 , and one end of the guide bar 13 is inserted into the guide hole 331 .

[0057] A positioning block 34 is disposed in the middle of a side of the bottom plate 3 away from the upper cover 1 , and a side of the positioning block 34 away from the bottom plate 3 is coated with thermal conductive silicone grease 341 .

[0058] The height of the front shovel teeth 31 is 3 to 6 millimeters, and the thickness of the front shovel teeth 31 is 0.15 millimeters; the height of the rear shovel teeth 32 is 3 to 6 millimeters, and the thickness of the rear shovel teeth 32 is 0.15 millimeters.

[0059] The interval 35 between the front shovel tooth 31 and the nearest rear shovel tooth 32 is 2 millimeters; the length of the front shovel tooth 31 is 20 millimeters, and the length of the rear shovel tooth 32 is 20 millimeters.

[0060] The liquid inlet pipe 21 includes a refrigerant 4, and the flow rate of the refrigerant 4 is 0.5 to 2.5 liters per minute; the pressure of the refrigerant 4 in the liquid inlet pipe 21 is greater than the pressure of the refrigerant 4 in the liquid outlet pipe 11.

[0061] The refrigerant medium 4 is 25% propylene glycol or 25% ethylene glycol.

[0062] The supplementary description of the present invention is as follows: The actual use requirement of the present invention is to stabilize the shell temperature of a power chip of less than or equal to 800 watts at 70 to 86 degrees Celsius.

[0063] Embodiment 1: See also Figure 1 — Fig.28A side-inlet and side-outlet end cover center slot drainage liquid cooling device, the device comprises an upper cover 1, a drainage channel 2 and a bottom plate 3; one end of the upper cover 1 is connected to a liquid inlet pipe 21 of the drainage channel 2, the other end of the drainage channel 2 is a liquid outlet 22, the liquid outlet 22 faces the middle of the bottom plate 3, a plurality of front shovel teeth 31 are evenly distributed on the bottom plate 3 at the front side of the liquid outlet 22, and the front shovel teeth 31 are all perpendicular to the liquid outlet 22, and a plurality of rear shovel teeth 32 are evenly distributed on the bottom plate 3 at the rear side of the liquid outlet 22, and the rear shovel teeth 32 are all perpendicular to the liquid outlet 22; the four sides of the bottom plate 3 are connected to the four sides of the upper cover 1, and the end of the upper cover 1 away from the liquid inlet pipe 21 is connected to one end of the liquid outlet pipe 11.

[0064] When in use, the refrigerant 4 first enters the liquid inlet pipe 21, and then flows along the drainage channel 2 to the liquid outlet 22, and then flows downward from the liquid outlet 22 to the middle of the bottom plate 3. At this time, the refrigerant 4 with a lower temperature flushes the middle of the bottom plate 3 with a higher temperature, so the refrigerant 4 cools the middle of the bottom plate 3; a part of the refrigerant 4 moves along the front shovel teeth 31, and the refrigerant 4 with a lower temperature contacts the front shovel teeth 31 with a higher temperature, so the refrigerant 4 cools the front shovel teeth 31, and then The front shovel teeth 31 cool the bottom plate 3, and then the part of the refrigerant 4 moves along the side wall of the bottom plate 3, and then the part of the refrigerant 4 moves to the liquid outlet pipe 11; another part of the refrigerant 4 moves along the rear shovel teeth 32, and the refrigerant 4 with a lower temperature contacts the rear shovel teeth 32 with a higher temperature, and the refrigerant 4 cools the rear shovel teeth 32, and then the rear shovel teeth 32 cool the bottom plate 3; then the part of the refrigerant 4 moves along the side wall of the bottom plate 3 to the liquid outlet pipe 11; the refrigerant 4 in the liquid outlet pipe 11 leaves the device; see Figure 15-17 , the temperature at the chip is relatively high, with the highest point being about 82.4 degrees Celsius. Under the cooling effect of the refrigerant 4, the highest temperature of the upper cover 1 is lower than 75 degrees Celsius, and the highest temperature other than the connection between the bottom plate 3 and the chip is lower than 75 degrees Celsius; see Figure 18-19 In the bottom view, the temperature of the front shovel teeth 31 and the rear shovel teeth 32 near the chip is relatively high, with the highest temperature being about 78.2 degrees Celsius. In the top view, the highest temperature of the front shovel teeth 31 and the rear shovel teeth 32 near the liquid outlet 22 is about 67 degrees. It can be concluded that the refrigerant 4 contacts the front shovel teeth 31 and the rear shovel teeth 32, thereby reducing the temperature of the front shovel teeth 31 and the rear shovel teeth 32; see Figure 20-21 In the top view, the temperature of the refrigerant 4 between the front shovel teeth 31 and the rear shovel teeth 32 is about 64 to 58 degrees. In the bottom view, the temperature of the refrigerant 4 near the chip is higher, with a maximum of about 69.5 degrees Celsius, which is lower than the temperature of the chip on the bottom plate 3. Therefore, the refrigerant 4 can cool the bottom plate 3, the front shovel teeth 31, and the rear shovel teeth 32, thereby cooling the chip; see Figure 22-23The temperature of the refrigerant 4 in the liquid inlet pipe 21 is about 49.8 degrees Celsius, and the temperature of the refrigerant 4 in the liquid outlet pipe 11 is about 63.7 to 61.9 degrees Celsius. The temperature of the refrigerant 4 in the liquid outlet pipe 11 is higher than that of the refrigerant 4 in the liquid inlet pipe 21. The heat of the increased temperature is absorbed by the refrigerant 4 from the bottom plate 3, the front shovel teeth 31, and the rear shovel teeth 32. Therefore, the refrigerant 4 can cool the bottom plate 3, the front shovel teeth 31, and the rear shovel teeth 32, thereby achieving the effect of cooling the chip; please refer to Figure 24-26 It can be seen that the pressure of the refrigerant 4 gradually decreases during its flow, that is, the pressure loss is relatively strong, so the device has a good heat dissipation capacity; please refer to Figure 27-Figure 28 It can be seen that the flow rate of the refrigerant 4 from the liquid outlet 22 is relatively large, so the refrigerant 4 has a better flushing effect on the middle part of the bottom plate 3. When the refrigerant 4 flows between the front shovel teeth 31 and the rear shovel teeth 32, the flow rate is relatively small, so the contact time between the refrigerant 4 and the front shovel teeth 31 and the rear shovel teeth 32 is relatively long, and the refrigerant 4 has a better cooling effect on the shovel teeth 31 and the rear shovel teeth 32.

[0065] Embodiment 2: The basic content is the same as that of Example 1, except that: See also Figure 1 — Fig.11 The end of the upper cover 1 close to the liquid outlet pipe 11 is a guide cavity 12, and the side wall of the guide cavity 12 forms a certain angle 121 with the plane where the outlet pipe 11 is located. A connecting plate 33 is provided on the bottom plate 3, and the end of the connecting plate 33 close to the guide cavity 12 matches the shape of the guide cavity 12.

[0066] When in use, the cross-section of the guide cavity 12 is triangular, so the guide cavity 12 guides the refrigerant 4 on both sides of the guide cavity 12 to the liquid outlet pipe 11, which is beneficial to the flow of the refrigerant 4, reduces the pressure difference between the liquid inlet pipe 21 and the liquid outlet pipe 11, and thus reduces the energy consumption of the circulating refrigerant 4; the connecting plate 33 protrudes from the bottom plate 3 to facilitate the welding positioning of the bottom plate 3 and the upper cover 1.

[0067] Embodiment 3: The basic content is the same as that of Example 1, except that: See also Figure 1 — Fig.11The upper cover 1 is provided with a guide bar 13, the guide bar 13 is parallel to the front shovel teeth 31 and the rear shovel teeth 32, the front end of the guide bar 13 exceeds the front end of the front shovel teeth 31, and the rear end of the guide bar 13 exceeds the rear end of the rear shovel teeth 32. There are two guide bars 13, and the two guide bars 13 are symmetrically distributed along the center of the front shovel teeth 31 and the rear shovel teeth 32; the connecting plate 33 is provided with a guide hole 331, and one end of the guide bar 13 is inserted into the guide hole 331. Preferably, there is a gap 35 between the front shovel teeth 31 and the rear shovel teeth 32.

[0068] When in use, the two guide bars 13 are respectively located on both sides of the gap 35, so the two guide bars 35 seal the gap 35 from both sides of the gap 35, that is, when the refrigerant 4 flows along the gap 35, it can only flow along the front shovel teeth 31 or the rear shovel teeth 32, that is, the contact between the refrigerant 4 and the front shovel teeth 31 and the rear shovel teeth 32 is guaranteed, that is, the cooling effect of the refrigerant 4 on the front shovel teeth 31 and the rear shovel teeth 32 is guaranteed; one end of the guide bar 13 is inserted into the guide hole 331 to facilitate positioning during processing.

[0069] Embodiment 4: The basic content is the same as that of Example 1, except that: See also Figure 1 — Fig.13 A positioning block 34 is provided in the middle of a side of the bottom plate 3 away from the upper cover 1 , and a side of the positioning block 34 away from the bottom plate 3 is coated with thermal conductive silicone grease 341 .

[0070] When in use, one side of the chip is connected to the thermal grease 341, so the heat of the chip is transferred to the thermal grease 341, and then the thermal grease 341 transfers the heat to the positioning block 34, and then the positioning block 34 transfers the heat to the bottom plate 3, and then the refrigerant 4 absorbs the heat of the bottom plate 3 to achieve a cooling effect on the chip.

[0071] Embodiment 5: The basic content is the same as that of Example 1, except that: See also Figure 1 — Fig.12 The height of the front shovel tooth 31 is 3 to 6 mm, and the thickness of the front shovel tooth 31 is 0.15 mm; the height of the rear shovel tooth 32 is 3 to 6 mm, and the thickness of the rear shovel tooth 32 is 0.15 mm. The interval 35 between the front shovel tooth 31 and the nearest rear shovel tooth 32 is 2 mm; the length of the front shovel tooth 31 is 20 mm, and the length of the rear shovel tooth 32 is 20 mm. Preferably, the area where all the front shovel teeth 31 are arranged together is the front shovel tooth area 311, and the width of the front shovel tooth area 311 is 45.65 mm. The area where all the rear shovel teeth 32 are arranged together is the rear shovel tooth area 321, and the width of the rear shovel tooth area 321 is 45.65 mm.

[0072] When used, the lengths of the front shovel tooth area 311 and the rear shovel tooth area 321 are both 45.65 mm. At this time, the areas of the front shovel tooth area 311 and the rear shovel tooth area 321 are moderate, and the cooling effect on the chip is better. If the front shovel tooth area 311 and the rear shovel tooth area 321 are too large or too small, the cooling effect on the chip will be reduced; the height of the front shovel teeth 31 and the rear shovel teeth 32 is three to six millimeters, and the contact area with the refrigerant 4 is large, which is beneficial to the cooling effect of the refrigerant 4. If the height of the front shovel teeth 31 and the rear shovel teeth 32 is greater than six millimeters, the longitudinal height of the device will be large, which is not conducive to the coordination of the device with other devices. If the height of the shovel teeth 32 is less than three millimeters, the contact area between the front shovel teeth 31, the rear shovel teeth 32 and the refrigerant 4 will be reduced, so the cooling effect will be reduced; the interval 35 between the front shovel teeth 31 and the nearest rear shovel teeth 32 is two millimeters, and the interval 35 provides a flow space for the refrigerant 4 flowing out of the liquid outlet 22, so that the refrigerant 4 can flow between all the front shovel teeth 31 and the rear shovel teeth 32; the thickness of the front shovel teeth 31 and the rear shovel teeth 32 is 0.15 millimeters. At this time, the contact area between the front shovel teeth 31 and the rear shovel teeth 32 and the refrigerant 4 is larger, which improves the cooling effect, and at this thickness, the stability of the front shovel teeth 31 and the rear shovel teeth 32 is better, which is conducive to long-term use.

[0073] Embodiment 6: The basic content is the same as that of Example 1, except that: See also Figure 1 — Fig.23 The liquid inlet pipe 21 includes a refrigerant 4, and the flow rate of the refrigerant 4 is 0.5 to 2.5 liters per minute; the pressure of the refrigerant 4 in the liquid inlet pipe 21 is greater than the pressure of the refrigerant 4 in the liquid outlet pipe 11. The refrigerant 4 is 25% propylene glycol or 25% ethylene glycol.

[0074] When used, the temperature of the refrigerant 4 in the liquid inlet pipe 21 is about forty to fifty degrees Celsius, which is sufficient to cool the chip and will not cause condensed water droplets to appear outside the chip; the pressure of the refrigerant 4 in the liquid inlet pipe 21 is greater than the pressure of the refrigerant 4 in the liquid outlet pipe 11, so the refrigerant 4 will not flow back, that is, the flow effect of the refrigerant 4 is guaranteed, and then the cooling effect of the device is guaranteed; the flow rate of the refrigerant 4 is 0.5 to 2.5 liters per minute, and this flow rate can ensure the cooling effect of the refrigerant; the refrigerant 4 is 25% propylene glycol or 25% ethylene glycol, and the above two types of refrigerants 4 have good heat exchange properties, so they are suitable for use in the present invention.

[0075] The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the contents disclosed by the present invention should be included in the protection scope recorded in the claims.
