Description

Technical Field

[0001] The present invention relates to the technical field of radiator structures, in particular to a 3D radiator structure. Background Art

[0002] At present, the heat dissipation technologies of electronic components mainly include air cooling technology and liquid cooling technology. Air cooling technology includes natural convection air cooling technology and forced convection air cooling technology. Natural convection air cooling technology is mainly used for electronic devices with low heat generation per unit volume, while forced convection air cooling technology is generally used in combination with heat pipes and temperature dispersion board technology.

[0003] Different types of three-dimensional space temperature equalizing plate structures on the market in the prior art only include a temperature equalizing plate mechanism and a number of upwardly protruding heat pipes. The inner cavity of the connection position of the heat pipe and the cover plate of the temperature equalizing plate mechanism is an equal-diameter structure from top to top. During actual heat exchange, the equal-diameter structure will not cause any rate change of the vaporized medium. Therefore, during the actual heat exchange process, the conduction performance of the entire radiator cannot be significantly improved. It is necessary to set more heat pipes to meet the demand for increasing the heat dissipation, which greatly increases the cost of the product. Summary of the invention

[0004] In view of the above problems, the present invention provides a 3D heat sink structure, which improves the heat transfer conductivity of the heat sink and reduces the economic cost without increasing the number of heat pipes.

[0005] A 3D heat sink structure, characterized in that it comprises:

[0006] A base, comprising a lower bottom plate and an outer ring, wherein the outer ring is arranged along the edge of the lower bottom plate to form an inner cavity;

[0007] The capillary structure includes a bottom plate capillary structure and a plurality of convex supporting capillary structures;

[0008] Acceleration loop structure;

[0009] Upper cover;

[0010] A number of capillary heat pipes;

[0011] The upper surface of the base is covered with the upper cover, and a plurality of heat pipe positioning holes are arrayed on the upper cover. The bottoms of the plurality of capillary heat pipes are welded to the corresponding heat pipe positioning holes. A capillary cone with a closing end from bottom to top is arranged at a position of the capillary structure corresponding to the accelerating circulation structure. The center of the accelerating circulation positioning structure is positioned at the center of the circle of the closing capillary cone. The central guide area formed by the combination of the closing capillary cone and the accelerating circulation positioning structure is a closing cavity from bottom to top. The bottom end of the inner wall of the heat pipe is supported on the closing capillary cone to form a capillary connection structure.

[0012] It is further characterized by:

[0013] The accelerating circulation structure is a bottom-up conical structure that imitates the conical capillary frustum, and the conical frustum is arranged at a coaxial position of the conical capillary frustum;

[0014] The outer wall of the closed cone structure is arranged in close contact with the inner wall of the closed capillary cone, and the inner cavity of the closed cone structure is a closed cavity from bottom to top, which makes the positioning of the heat pipe stable and reliable;

[0015] An adjustable structure of circumferential partition grooves is provided on the upper part of the closed capillary frustum, and the top of the closed capillary frustum is adapted and adjusted according to the aperture of the heat pipe positioning hole, so that the capillary heat pipe can be reliably supported and positioned on the top outer wall of the closed capillary frustum;

[0016] The closed cone structure includes an inner layer structure and an outer layer structure. The outer layer structure is an adjustable structure with a bottom connection and a circumferential partition groove on the top. The inner layer structure is a structure with a central hole and guide plates distributed on the periphery. The guide plate structure is mounted on the upper convex positioning rod at the corresponding position, which makes the central position of the closed cone structure reliable and makes the outer layer structure reliably fit the inner wall of the closed capillary cone, so that the positioning assembly is fast and efficient.

[0017] The accelerated circulation structure is specifically a central arrangement member such as a flower tooth, a cross powder column, or a plum blossom powder column. The central arrangement member is fixedly mounted directly below the center of the heat pipe positioning hole and fixed to the corresponding upper surface of the bottom plate capillary structure. The outer peripheral wall of the central arrangement member and the inner wall of the closed cone structure are combined to form a closed cavity from bottom to top.

[0018] Preferably, the accelerated circulation structure is a capillary structure or a groove structure.

[0019] After adopting the technology of the present invention, the lower base plate contacts the heat source to transfer heat, and the internal medium is heated and vaporized. The heated medium gas passes through the bottom-up closed cavity formed by the closed capillary cone and the accelerated circulation positioning structure. Due to the change in the cross-sectional size, the speed is accelerated, so that it quickly circulates into the inner cavity of the capillary heat pipe, and finally the heat is dissipated by heat conduction. The gas is cooled and liquefied, and under the action of gravity, it flows back to the heat source along the capillary heat pipe, the closed capillary cone, and the bottom plate capillary structure, and is heated and evaporated again, and the cycle is repeated. Because the central guide area formed by the closed capillary cone and the accelerated circulation positioning structure is a bottom-up closed cavity, the bottom-up closed cavity accelerates the circulation rate of the internal medium, which improves the heat exchange conductivity of the radiator without increasing the number of heat pipes and reduces the economic cost.

DETAILED DESCRIPTION

[0030] A 3D heat sink structure, see Figure 1-Figure 8 , which includes a base 10, a capillary structure 20, an accelerated circulation structure 30, an upper cover 40, and a plurality of capillary heat pipes 50;

[0031] The base 10 includes a lower bottom plate 11 and an outer ring 12, wherein the outer ring 12 is arranged along the edge of the lower bottom plate 11 to form an inner cavity 13;

[0032] The capillary structure 20 includes a bottom plate capillary structure 21 and a plurality of upper convex supporting capillary structures 22;

[0033] The upper surface of the base 10 is covered with an upper cover 40, and a plurality of heat pipe positioning holes 41 are arrayed on the upper cover 40. The bottoms of a plurality of capillary heat pipes 50 are fixedly connected to the corresponding heat pipe positioning holes 41. The capillary structure 20 is provided with a closed capillary cone 23 from bottom to top at the position corresponding to the accelerating circulation structure 30. The center of the accelerating circulation positioning structure 30 is positioned at the center of the closed capillary cone 23. The central guide area formed by the closed capillary cone 23 and the accelerating circulation positioning structure 30 is a closed cavity from bottom to top. The bottom end of the inner wall of the heat pipe 50 is supported on the closed capillary cone 23 to form a capillary connection structure.

[0034] For specific embodiments, see Figure 1-Figure 5 The accelerating circulation structure 30 is a bottom-up conical cone structure 31 that is shaped like the conical cone 23, and the conical cone 31 is arranged at a coaxial position of the conical cone 23;

[0035] The outer wall of the closed cone structure 31 is arranged in close contact with the inner wall of the closed capillary cone 23, and the inner cavity of the closed cone structure 31 is a closed cavity from bottom to top, which makes the positioning of the closed capillary cone 23 stable and reliable, and further makes the position of the capillary heat pipe 50 stable and reliable;

[0036] An adjustable structure of a circumferential partition groove 231 is provided on the upper part of the closed capillary cone 23. The top of the closed capillary cone 23 is adapted and adjusted according to the aperture of the heat pipe positioning hole 41, so that the capillary heat pipe 50 can be reliably supported and positioned on the top outer wall of the closed capillary cone 23.

[0037] The closing cone structure 31 includes an inner layer structure 311 and an outer layer structure 312. The outer layer structure 312 is an adjustable structure which is connected at the bottom and provided with a circumferential partition groove 3121 at the top. The inner layer structure 311 is a structure having a central hole 3111 and guide plates 3112 distributed at the periphery. The guide plates 3112 are mounted on the upper convex positioning rods 14 at corresponding positions, which ensures that the central position of the closing cone structure 31 is reliable and that the outer layer structure 312 is reliably fitted to the inner wall of the closing capillary cone 23, thereby making the positioning and assembly quick and efficient.

[0038] In specific implementation, the acceleration circulation structure 30 can also be a central arrangement component with equal diameters at the top and bottom. The central arrangement component is fixedly installed just below the center of the heat pipe positioning hole 41 and the corresponding upper surface of the fixed bottom plate capillary structure 21. The outer peripheral wall of the central arrangement component and the inner wall of the closing cone structure 23 are combined to form a closing cavity from bottom to top.

[0039] In specific implementation, the central arrangement member is specifically a flower tooth 32 , a cross powder column 33 or a plum blossom powder column 34 .

[0040] During specific implementation, the accelerating circulation structure 30 is specifically a capillary structure or a groove structure.

[0041] Its working principle is as follows: the lower base plate contacts the heat source to transfer heat, and the internal medium is heated and vaporized. The heated medium gas passes through a bottom-up closed cavity formed by the combination of the closed capillary cone and the accelerated circulation positioning structure. Due to the change in the cross-sectional size, the speed is accelerated, so that it quickly circulates into the inner cavity of the capillary heat pipe, and finally the heat is dissipated by conduction. The gas is cooled and liquefied, and under the action of gravity, it flows back to the heat source along the capillary heat pipe, the closed capillary cone, and the capillary structure of the bottom plate, and is heated and evaporated again, and the cycle is repeated. Because the central guide area formed by the combination of the closed capillary cone and the accelerated circulation positioning structure is a bottom-up closed cavity, the bottom-up closed cavity accelerates the circulation rate of the internal medium. Without increasing the number of heat pipes, it improves the heat exchange conductivity of the radiator and reduces the economic cost.
