Description

Technical Field

[0001] This utility model belongs to the field of chassis heat dissipation technology, and specifically relates to a high-efficiency heat dissipation device for liquid-cooled chassis. Background Technology

[0002] A liquid cooling radiator is a device that uses a circulating coolant to dissipate heat.

[0003] Water cooling systems utilize pumps to circulate coolant within the heat pipes for heat dissipation. The heat-absorbing section on the radiator (called a heat sink in liquid cooling systems) absorbs heat from the CPU, northbridge, and GPU. The heat absorbed by this section is then exhausted to the outside of the computer via a radiator designed on the back of the chassis, offering advantages such as quiet operation and rapid heat dissipation.

[0004] Existing radiators, such as the heat dissipation section in CN104866043A, operate by introducing coolant carrying a heat source into the heat exchange tubes via a connecting pipe from the heat head. The heat exchange tubes transfer heat to the fins through heat exchange. A fan is activated, blowing the heat from the fin surface to the outside, thus dissipating heat from the fin surface. According to the heat exchange principle, the coolant flowing through the heat exchange tubes is cooled and transferred to the liquid cooling inlet inside the liquid-cooled chassis to cool the heat source within the chassis. This cycle completes the heat dissipation. When the fan is operating, its air inlet is located inside the chassis. The fan draws air from inside the liquid-cooled chassis and blows it away from the fin surface. When the temperature inside the liquid-cooled chassis rises due to passive heat dissipation from the working components, the air blown by the fan onto the fin surface is hot air. The temperature difference between the air blown onto the fin surface and the fin surface decreases, resulting in reduced heat dissipation efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency heat dissipation device for a liquid-cooled chassis to solve the technical problems mentioned in the background section.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A high-efficiency heat dissipation device for a liquid-cooled chassis includes: a mounting plate, right-angle hinges, and a shell frame; the mounting plate is a plate-shaped structure with a rectangular opening in the center, and a cuboid shell frame is embedded in the rectangular opening of the mounting plate. The two sides of the shell frame are connected to the mounting plate by right-angle hinges, and the shell frame can be rotated 90 degrees by the right-angle hinges; metal sheet-like fins are evenly arranged on the shell frame, and the fins are fixed by heat exchange tubes through multiple folds. The two ends of the heat exchange tubes are liquid inlet and liquid outlet, respectively. Two sets of circular holes are provided on each side of the mounting plate, and a fan is fixed to each of the two sets of circular holes on one side.

[0008] Furthermore: the right-angle hinge consists of two sets, including a fixed hinge frame and a movable hinge frame; the side of the rectangular opening on the mounting plate is provided with a first hinge fixing hole for connecting the fixed hinge frame, and the fixed hinge frame is bolted to the first hinge fixing hole; the side of the shell frame is provided with a second hinge fixing hole for connecting the movable hinge frame; the movable hinge frame is bolted to the second hinge fixing hole; the fixed hinge frame and the movable hinge frame are respectively rotatably fitted with a long connecting rod and a short connecting rod at their middle parts by a hinge shaft, the length of the short connecting rod being half that of the long connecting rod, and the long connecting rod being located on the side near the shell frame's rotation axis; the long connecting rod and the short connecting rod in the same set are parallel to each other, and the ends of the short connecting rod on the fixed hinge frame and the long connecting rod on the movable hinge frame are hinged to each other; the middle parts of the two sets of long connecting rods are hinged by a central hinge shaft.

[0009] Furthermore, to avoid the long and short connecting rods on the right-angle hinge being exposed after folding and affecting the aesthetics, both the fixed hinge frame and the movable hinge frame have concave structures on their opposite surfaces after folding to form a receiving compartment, in which the long and short connecting rods on the fixed hinge frame and the movable hinge frame are stored after folding.

[0010] Furthermore, to prevent the rectangular opening on the mounting plate from being exposed after the frame is rotated 90 degrees, which would cause excessive dust to enter, a plate-shaped or mesh-like dust baffle is vertically fixed on one side of the frame near the rotation axis. After the frame is rotated 90 degrees, the dust baffle rotates to the rectangular opening on the mounting plate, thus covering the rectangular opening on the mounting plate.

[0011] Furthermore, in order to protect the fins and to prevent the fan blades from accidentally injuring the user, a set of protective nets is provided at each of the two sets of round holes on the side of the housing away from the fan, and a set of protective nets is installed on the side of the two sets of fans away from the housing.

[0012] Furthermore, to facilitate the flipping of the housing, a set of handles is provided on the side of the housing away from the fan.

[0013] Furthermore: In order to ensure that the rotating shell does not affect the liquid inlet and outlet of the heat exchange tube, the liquid inlet is connected to a pipe joint to form a hot head by a flexible connecting pipe; the liquid outlet is connected to a pipe joint to form a cold head by a flexible connecting pipe.

[0014] Furthermore, in order to facilitate the passage of the connecting pipe, the dust baffle plate is provided with an opening to facilitate the passage of the connecting pipe, forming a reserved opening.

[0015] Furthermore, to facilitate connection to the liquid cooling chassis, the mounting plate is provided with at least four sets of countersunk holes.

[0016] Furthermore, in order to fix the position of the shell after it is flipped, the central hinge shaft is a damping shaft.

[0017] In summary, this utility model has the following beneficial effects:

[0018] ① High heat dissipation efficiency: With the establishment of a flip-up shell, when efficient heat dissipation is required, the entire shell is flipped around a right-angle hinge by pulling the handle until the dust baffle on the shell seals the rectangular opening of the mounting plate. The heat dissipation principle is basically the same as that of conventional liquid cooling. The difference is that after flipping, the fan air inlet is not located inside the chassis, but outside the chassis. That is to say, the air blown by the fan onto the surface of the fins is cold air or room temperature air from the outside. The temperature difference between the air blown by the fan onto the surface of the fins and the temperature of the fins will increase. The greater the temperature difference, the better the heat exchange efficiency, thereby improving the heat dissipation effect of the liquid-cooled chassis under continuous high temperature conditions.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Example:

[0029] Please see Figures 1-7 The present invention provides the following technical solution:

[0030] A high-efficiency heat dissipation device for a liquid-cooled chassis includes: a mounting plate 1, a right-angle hinge 2, and a shell frame 3; the mounting plate 1 is a plate-shaped structure with a rectangular opening in the middle, and a cuboid shell frame 3 is embedded in the rectangular opening of the mounting plate 1. The two sides of the shell frame 3 are connected to the mounting plate 1 by the right-angle hinge 2, and the shell frame 3 can be rotated 90 degrees by the right-angle hinge 2; metal sheet-like fins 4 are evenly arranged on the shell frame 3, and the fins 4 are fixed by heat exchange tubes 5 through multiple folds. The two ends of the heat exchange tubes 5 are liquid inlet 51 and liquid outlet 52, respectively. There are two sets of round holes on each side of the mounting plate 1, and a fan 6 is fixed outside each of the two sets of round holes on one side.

[0031] The right-angle hinge 2 consists of two sets, including a fixed hinge frame 21 and a movable hinge frame 22. The side of the rectangular opening on the mounting plate 1 has a first hinge fixing hole 10 for connecting the fixed hinge frame 21. The fixed hinge frame 21 is bolted to the first hinge fixing hole 10. The side of the shell frame 3 has a second hinge fixing hole 31 for connecting the movable hinge frame 22. The movable hinge frame 22 is bolted to the second hinge fixing hole 31. The fixed hinge frame 21 and the movable hinge frame 22 are connected by a hinge axis at their midpoints. The rotating assembly includes a long connecting rod 23 and a short connecting rod 24. The length of the short connecting rod 24 is half that of the long connecting rod 23. The long connecting rod 23 is located on the side near the pivot point of the housing 3. The long connecting rod 23 and the short connecting rod 24 in the same group are parallel to each other. The ends of the short connecting rod 24 on the fixed hinge frame 21 and the long connecting rod 23 on the movable hinge frame 22 are hinged to each other. The ends of the short connecting rod 24 on the movable hinge frame 22 and the long connecting rod 23 on the fixed hinge frame 21 are hinged to each other. The middle of the two groups of long connecting rods 23 is hinged by a central hinge shaft 25.

[0032] To prevent the long connecting rods 23 and short connecting rods 24 on the right-angle hinge 2 from being exposed after folding and affecting the aesthetics, the fixed hinge frame 21 and the movable hinge frame 22 are provided with concave structures on their opposite surfaces after folding to form a receiving compartment 26. After folding, the long connecting rods 23 and short connecting rods 24 on the fixed hinge frame 21 and the movable hinge frame 22 are stored in the receiving compartment 26.

[0033] To prevent the rectangular opening on the mounting plate 1 from being exposed after the shell frame 3 is rotated 90 degrees, which would cause excessive dust to enter, a plate-shaped or mesh-like dust baffle 9 is vertically fixed on the side of the shell frame 3 near the rotation axis. After the shell frame 3 is rotated 90 degrees, the dust baffle 9 rotates to the rectangular opening on the mounting plate 1 to cover the rectangular opening on the mounting plate 1.

[0034] In order to protect the fin plate 4 and to prevent the fan blades from accidentally injuring the user, a set of protective nets 7 are provided at each of the two sets of round holes on the side of the housing 3 away from the fan 6, and a set of protective nets 7 are installed on each of the two sets of fans 6 on the side away from the housing 3.

[0035] To facilitate the flipping of the housing 3, a set of handles 8 are provided on the side of the housing 3 away from the fan 6.

[0036] In order to ensure that the rotating shell 3 does not affect the liquid inlet and outlet of the heat exchange tube 5, the liquid inlet 51 is connected to a pipe joint by a flexible connecting pipe 11 to form a hot head 12; the liquid outlet 52 is connected to a pipe joint by a flexible connecting pipe 11 to form a cold head 13.

[0037] To facilitate the passage of the connecting pipe 11, the dust baffle 9 has an opening 91 for the connecting pipe 11 to pass through.

[0038] To facilitate connection to the liquid cooling chassis, the mounting plate 1 is provided with at least four sets of countersunk holes 14.

[0039] In order to fix the position of the housing 3 after it is flipped, the central hinge shaft 25 is a damping shaft.

[0040] Brief description of usage:

[0041] When using it, an opening needs to be reserved on the liquid cooling chassis for the housing 3 to be accommodated. The mounting plate 1 is fixed to the reserved opening on the liquid cooling chassis by using bolts through the countersunk holes 14. The hot head 12 is connected to the liquid cooling outlet inside the liquid cooling chassis (such as the outlet of the CPU water block or the outlet of the water-cooled GPU), and the cold head 13 is connected to the liquid cooling inlet inside the liquid cooling chassis (such as the inlet of the CPU water block or the inlet of the water-cooled GPU).

[0042] In normal use, such as Figure 2As shown, the usage method is the same as that of a regular liquid-cooled radiator. Coolant with a heat source enters from the heat head 12, passes through the connecting pipe 11, and is introduced into the heat exchange tube 5. The heat exchange tube 5 transfers heat to the fins 4 through heat exchange. The fan 6 is activated, blowing the heat from the surface of the fins 4 to the outside, thus dissipating heat from the surface of the fins 4. According to the heat exchange principle, the coolant flowing through the heat exchange tube 5 of the fins 4 is cooled. The cooled coolant is discharged from the outlet 52 to the connecting pipe 11 connected to the cold head 13, and then transferred to the liquid coolant via the connecting pipe 11 and the cold head 13. The liquid cooling inlet inside the chassis cools the heat source inside the chassis, and this cycle completes the heat dissipation. When fan 6 is working, the air inlet of fan 6 is located inside the chassis. Fan 6 draws air from inside the liquid-cooled chassis and blows away the heat from the surface of fin 4. When the temperature inside the liquid-cooled chassis rises due to passive heat dissipation from the working components, the air blown by fan 6 onto the surface of fin 4 is hot air. The temperature difference between the air blown by fan 6 onto the surface of fin 4 and the temperature of fin 4 will decrease, resulting in reduced heat dissipation efficiency.

[0043] Therefore, based on the above principles, when efficient heat dissipation is required, such as Figure 1 As shown, by pulling the entire shell frame 3 with the handle 8, the entire shell frame 3 rotates around the right-angle hinge 2 until the dust baffle 9 on the shell frame 3 seals the rectangular opening of the mounting plate 1. The heat dissipation principle is basically the same as the above principle. The difference is that after the fan 6 is rotated, the air inlet is not located inside the chassis, but outside the chassis. That is to say, the air blown by the fan 6 onto the surface of the fin plate 4 is cold air or room temperature air from the outside. The temperature difference between the air blown by the fan 6 onto the surface of the fin plate 4 and the temperature of the fin plate 4 will become larger. The larger the temperature difference, the better the heat exchange efficiency, thereby improving the heat dissipation effect of the liquid-cooled chassis under continuous high temperature conditions.

[0044] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
