[0054] Specifically, the lower convex portion includes a plurality of the first convex hulls, a plurality of the second convex hulls, a plurality of the third convex hulls and a plurality of the fourth convex hulls, wherein:

[0055] A plurality of the second convex hulls are stacked and arranged in a fan-shaped manner to generate multi-path spoilers;

[0058] The plurality of fourth convex hulls are divided into two groups and arranged in parallel, and are respectively arranged on the other side of the first convex hull relative to the second convex hull, and on the other side of the third convex hull relative to the second convex hull.

[0059] Specifically, the double composite cover plate further comprises a plurality of first clamping grooves corresponding to the plurality of blowing plates, so as to realize the clamping connection between the blowing plates and the double composite cover plate, and each of the first clamping grooves is arranged between adjacent fourth convex bumps.

[0060] Specifically, the bottom plate includes:

[0064] Specifically, the coating structure includes:

[0066] A cover plate is clamped above the blowing plate and the aluminum plate and is parallel to the bottom plate, covering the top surface of the array of the blowing plates.

[0067] Specifically, the VC heat dissipation module further includes a temperature monitor connected to the double composite cover plate, which is used to monitor the temperature of the refrigerant medium in the VC heat dissipation module.

[0068] like Figure 1 As shown, an embodiment of the present application provides a three-dimensional VC heat dissipation module, including: a base plate 1, a double composite cover plate 2, a plurality of blowing plates 3, a temperature monitor 5, an injection pipe 6 and a coating structure, the coating structure including an aluminum plate 7 and a cover plate 8.

[0069] Specifically, Figure 2 , 4 As shown, the bottom plate 1 includes a bottom plate recess 11 and a bottom plate column protruding toward the double composite cover plate 2, which is used to support and clamp the double composite cover plate 2; the bottom plate 1 is integrally formed. The bottom plate column protruding toward the double composite cover plate 2 includes a clamping column 12 and a supporting column 13.

[0070] Combination Figure 2 , 3 As shown in , 4, the double composite cover plate 2 includes a base 21 parallel to the bottom plate 1, an upper raised portion 22 raised in the direction of the blowing plate 3, and a lower raised portion 23 raised in the direction of the bottom plate; the lower raised portion 23 and the upper raised portion 22 are both fixedly connected to the base 21 and integrally formed; the height of the lower raised portion 23 and the height of the upper raised portion 22 are matched with the depth of the depression of the bottom plate depression 11, so that when the double composite cover plate 2 is fixedly connected to the bottom plate 1, a flow channel 4 with a three-dimensional structure is formed inside; the base 21 of the double composite cover plate 2 also includes a liquid injection through hole 26 for connecting the liquid injection pipe 6 (such as Figure 6 The upper protrusion 22 is stamped on the base 21 toward the inflation plate 3 to cooperate with the lower protrusion 23 to form a flow channel 4 of a three-dimensional structure with different heights between the double composite cover plate 2 and the bottom plate 1, so as to make the turbulence stronger, improve the fluidity of the coolant, and enhance the heat dissipation effect. Specifically, the injection pipe 6 is fixedly connected to the double composite cover plate 2 and is used to inject the coolant.

[0071] Preferably, the double composite cover plate 2 is integrally formed by a stamping process.

[0072] Specifically, the height of the support column 13 is consistent with the depression depth of the bottom plate depression 11, the protrusion height of the upper protrusion 22, and the protrusion height of the lower protrusion 23, and is smaller than the height of the clamping column 12; the clamping column 12 is used to clamp with the double composite cover plate 2; the support column 13 is used to support the lower protrusion 23.

[0073] The shape of the double composite cover plate 2 installed above the bottom plate 1 matches the bottom plate 1, and the double composite cover plate 2 is fixedly connected to the bottom plate 1 through a brazing process, which has a simple process and low cost.

[0074] Specifically, Figure 3 , 4 As shown, the lower raised portion 23 includes a first bulge 231, a second bulge 232, a third bulge 233 and a fourth bulge 234 with equal raised heights; the first bulge 231, the second bulge 232 and the third bulge 233 are distributed on the base 21, and the cross-sectional shape parallel to the base is any one or more of a circle, a parallelogram, a rhombus, and a rectangle.

[0075] Specifically, the second convex hulls 232 are arranged in a fan-shaped stack to generate multi-path spoilers; Figure 2 The second convex hulls 232 shown are stacked in groups of three, and each group of two forms a fan-shaped structure. The two groups have opposite tendencies but are symmetrically distributed. When the coolant flows through one of the intersections, it will face three flow directions. Such a fan-shaped structure will greatly enhance the turbulence, thereby strengthening the circulation effect, making the flow channel of the entire circulation line rich and three-dimensional, thereby improving the heat dissipation effect of the entire heat dissipation module.

[0076] Specifically, the fourth convex hump 234 is in the shape of an elongated strip, distributed on the base 21 and the upper raised portion 22 , and separated at both ends of the double composite cover plate by the first convex hump 231 , the second convex hump 232 , and the third convex hump 233 .

[0077] Specifically, the cross-sections of the first convex 231 and the third convex 233 parallel to the base 21 are circular, and the first convex 231 is smaller than the third convex 233; the first convex 231 and the third convex 233 are arranged in a linear manner, distributed on both sides of the second convex 232 array, so as to enhance the spoiler effect. Preferably, the first convex 231 is equal to the third convex 233. The cross-sections of the first convex 231 and the third convex 233 parallel to the base 21 are parallelograms, rhombuses or squares, etc., and the corners of the two adjacent sides are arc-shaped, so that the coolant flowing therethrough can pass smoothly.

[0078] Specifically, the fourth convex bumps 234 are arranged in parallel on the base 21 to form a first array, and are arranged in parallel on the upper raised portion to form a second array; the shape of the fourth convex bumps 234 is adjusted according to the location and the location of the first card connection slot 24 and the second card connection slot 25. Specifically, the location refers to the base 21, or on the upper raised portion 22. Because the locations of the first card connection slot 24 and the second card connection slot 25 need to be avoided in some areas, the length of the fourth convex bumps 234 needs to be shortened to make way for the first card connection slot 24 and the second card connection slot 25. Correspondingly, the length of the first card connection slot 24 can also be adjusted, such as Figure 3 , 5 As shown, the lengths of the first engaging grooves 24 on the upper protrusion 22 are different, and the corresponding inflatable plate 3 also needs to adjust the engaging position to match the first engaging groove 24 .

[0079] This layout makes the flow channel multi-directional and has a three-dimensional structure. The refrigerant medium will face multiple choices of direction at a fork, forming a complete circulation route as a whole. This design greatly enhances the heat dissipation effect. Optionally, the refrigerant medium is ammonia, environmentally friendly chlorofluorocarbons, or water, air and other substances. Different refrigerants are set according to actual heat dissipation needs.

[0080] Preferably, the second convex hulls 232 may also be circular in cross section, evenly distributed between the linear array formed by the first convex hulls and the second convex hulls 232, or mixedly distributed with the first convex hulls 231 and the third convex hulls 233. Different shapes and arrangements may produce different spoiler effects.

[0081] Specifically, Figure 3 As shown, the double composite cover plate 2 further includes a first latching groove 24 and a second latching groove 25 distributed on the base 21 and the upper protruding portion 22 .

[0082] The first connecting grooves 24 are spaced apart between the adjacent fourth convex bumps 234 and are used to connect the inflation plate 3. Figure 5 , which is a schematic diagram of the blowing plate 3 being clamped on the double composite cover plate 2.

[0083] Specifically, the inflation plate 3 includes a lower clamping portion 31 and an upper clamping portion 32; the shape and size of the lower clamping portion 31 match the first clamping groove 24 of the double composite cover plate 2, and is used to clamp and fix the inflation plate 3 to the double composite cover plate 2;

[0084] The upper clamping portion is used to clamp and fix the inflation plate 3 and the cover plate 8 .

[0085] Specifically, in a group of blowing plates 3, the shapes of the lower clamping portions 31 of adjacent blowing plates 3 may be different, as long as they match the shapes of the corresponding first clamping grooves 24 to ensure the clamping connection between the two.

[0086] like Figure 5 As shown, each blowing plate has two lower clamping parts 31, which correspond to a first clamping groove 24 distributed on the base 21 and a first clamping groove 24 distributed on the upper protrusion 22. Each blowing plate 3 has three upper clamping parts 32, which correspond to the three clamping grooves (not shown) at the bottom of the cover plate 8, for clamping the blowing plate 3 and the cover plate 8.

[0087] Combination Figure 3 , 4 As shown in Figure 5, the second card-connecting groove 25 is distributed on the base 21 and the upper protrusion 22, and the shape of the second card-connecting groove 25 matches the shape of the card-connecting column 12, and is used to card-connect the bottom plate 1 and the double composite cover plate 2, and after card-connection, the card-connecting column 12 is higher than the double composite cover plate 2.

[0088] In one embodiment, the encapsulation structure of the three-dimensional VC heat dissipation module of the present application includes an aluminum plate 7 that is clamped to the first clamping groove 24 on the outermost side of the double composite cover plate 2, and the aluminum plate 7 is parallel to the blowing plate 3 and is encapsulated on the left and right sides of the array of the blowing plate 3, such as Figure 1 , 2 As shown, the aluminum plate 7 includes an aluminum plate lower clamping portion and an aluminum plate upper clamping portion of the same shape as the blowing plate 3, the shape and size of the aluminum plate lower clamping portion match the first clamping through groove 24 of the double composite cover plate 2, and is used to clamp and fix the aluminum plate 7 to the double composite cover plate 2; the aluminum plate upper clamping portion is used to clamp and fix the aluminum plate 7 to the cover plate 8. Specifically, the aluminum plate is a protective aluminum plate, such as a PCI heat sink aluminum plate.

[0089] In one embodiment, if Figure 7 As shown, the three-dimensional VC heat dissipation module of the present application also includes a temperature monitor 5 connected to the double composite cover plate 2, which is used to monitor the temperature of the refrigerant injected into the VC heat dissipation module. The temperature monitor 5 includes a connection structure, a temperature sensor and an alarm device (not shown). When the temperature exceeds the standard, the alarm device is triggered to sound an alarm to remind the user to replenish the refrigerant in time, thereby ensuring the efficient operation of the VC heat dissipation module and extending the service life of the VC heat dissipation module.

[0090] In one embodiment, if Figure 1 , 2As shown, the covering structure also includes a cover plate 8, which is installed above the blowing plate 3 and the aluminum plate 7 and is parallel to the bottom plate 1; the cover plate 8 includes a card groove, which matches the shape of the upper card part 32 and the card part on the aluminum plate to card and fix the blowing plate 3 and the aluminum plate 7.

[0091] In summary, by fixing the double composite cover plate 2 and the bottom plate 1, in addition to the injection through hole 26, an internal closed cavity is formed. After the coolant is injected, the coolant flows through the first convex 231, the second convex 232, the third convex 233 and the fourth convex 234 in sequence, filling the cavity. When flowing, disturbances will be formed when not passing through the fork formed by different convex structures, so that the heat dissipation effect of the overall structure is better.

[0092] In summary, the present application provides a VC heat dissipation module with a three-dimensional structure, including a base plate, a double-composite cover plate, a plurality of blowing plates and a covering structure; the base plate includes a base plate recessed portion and a base plate column protruding in the direction of the double-composite cover plate, for supporting and clamping the double-composite cover plate; the double-composite cover plate includes a base parallel to the base plate, an upper protrusion protruding in the direction of the blowing plate and a lower protrusion protruding in the direction of the base plate; the lower protrusion and the upper protrusion are both fixedly connected to the base and integrally formed; the height of the lower protrusion and the height of the upper protrusion are both matched with the recessed depth of the base plate recessed portion, so that when the double-composite cover plate is fixedly connected to the base plate, a three-dimensional structure flow channel is formed inside. The three-dimensional structure of the VC heat dissipation module of the present application is formed by using a variety of convex hulls to form a three-dimensional structure, and the convex hulls of different shapes are combined and arranged in an array to form a fan-shaped stack, generating a variety of spoiler structures to accelerate the spoiler and enhance the heat dissipation effect, and adopts a brazing process, which is simple and low in cost. It is a three-dimensional heat dissipation module with high heat dissipation and low cost, which can be widely used in electronic products to meet various application needs.
