Description

Technical Field

[0001] This invention relates to the technical field of heat sink structures, specifically a 3D heat sink structure. Background Technology

[0002] Currently, heat dissipation technologies for electronic components mainly fall into two categories: air cooling and liquid cooling. Air cooling technology includes natural convection air cooling and forced convection air cooling. Natural convection air cooling is mainly used for electronic components that generate relatively little heat per unit volume, while forced convection air cooling is generally used in conjunction with heat pipes and vapor chambers.

[0003] In the existing technology, various types of three-dimensional spatial vapor chamber structures all consist of only a vapor chamber mechanism and several upward-protruding heat pipes. The inner cavity at the connection point between the heat pipes and the cover plate of the vapor chamber mechanism is a constant diameter structure from top to bottom. In actual heat exchange, the constant diameter structure does not cause any rate change in the vaporization medium. Consequently, the overall heat transfer performance of the radiator cannot be significantly improved during the actual heat exchange process. It is necessary to add more heat pipes to meet the demand for increased heat dissipation, which greatly increases the cost of the product. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a 3D heat sink structure that improves the heat transfer conductivity of the heat sink and reduces economic costs without increasing the number of heat pipes.

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

[0006] The base includes a lower base plate and an outer circumference, wherein the outer circumference is arranged to form an inner cavity by closing off the edge of the lower base plate;

[0007] The capillary structure includes a base capillary structure and several upwardly convex support capillary structures.

[0008] Accelerate loop structures;

[0009] Top cover;

[0010] Several capillary heat pipes;

[0011] The upper surface of the base is covered with the upper cover, which has an array of heat pipe positioning holes. The bottoms of the capillary heat pipes are welded to the corresponding heat pipe positioning holes. The capillary structure is provided with a capillary cone that tapers from bottom to top at the position corresponding to the accelerating circulation structure. The center of the accelerating circulation structure is located at the center of the capillary cone. The central guiding area formed by the capillary cone and the accelerating circulation structure is a cavity that tapers from bottom to top. The bottom end of the inner wall of the heat pipe is supported by the capillary cone, forming a capillary interconnection structure.

[0012] Its further features are:

[0013] The accelerated circulation structure is a bottom-up tapered cone structure that mimics the shape of a tapered capillary cone, with the tapered cone arranged at the coaxial center of the tapered capillary cone.

[0014] The outer wall of the tapered frustum structure is arranged to fit the inner wall of the tapered capillary frustum, and the inner cavity of the tapered frustum structure is a tapered cavity from bottom to top, which makes the positioning of the heat pipe stable and reliable.

[0015] The upper part of the tapered capillary cone is provided with an adjustable structure with a circumferential groove. The top of the tapered capillary cone is adapted and adjusted according to the diameter of the heat pipe positioning hole, so that the capillary heat pipe is reliably supported and positioned on the top outer wall of the tapered capillary cone.

[0016] The tapered 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 groove at the top. The inner layer structure is a structure with a central hole and guide plates distributed around the periphery. The guide plate structure is fitted onto the corresponding upper protruding positioning rod, which ensures that the center position of the tapered cone structure is reliable and that the outer layer structure reliably fits the inner wall of the tapered capillary cone, making positioning and assembly fast and efficient.

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

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

[0019] With the technology of this invention, the bottom plate contacts the heat source for heat transfer, and the internal medium is heated and vaporized. The heated medium gas passes through a constricted cavity formed by the combination of a constricted capillary cone and an accelerating circulation structure, which is located from bottom to top. Due to the change in cross-sectional size, the speed is accelerated, and the gas quickly circulates into the inner cavity of the capillary heat pipe. Finally, heat is conducted and dissipated, and the gas is cooled and liquefied. Under the action of gravity, it flows back to the heat source along the capillary heat pipe, the constricted capillary cone, and the capillary structure of the bottom plate, where it is heated and evaporated again, repeating the cycle. Because the central guiding area formed by the combination of the constricted capillary cone and the accelerating circulation structure is a constricted cavity from bottom to top, the circulation rate of the internal medium is accelerated. This improves the heat transfer conductivity of the radiator and reduces economic costs without increasing the number of heat pipes. Attached Figure Description

Detailed Implementation

[0030] A 3D heat sink structure, see Figures 1-8 It includes a base 10, a capillary structure 20, an accelerated circulation structure 30, a top cover 40, and several capillary heat pipes 50.

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

[0032] The capillary structure 20 includes a base capillary structure 21 and several upwardly convex support capillary structures 22.

[0033] The upper surface of the base 10 is covered with a top cover 40, and the top cover 40 has a plurality of heat pipe positioning holes 41 arrayed on it. The bottom of a plurality of capillary heat pipes 50 is fixed to the corresponding heat pipe positioning holes 41. The capillary structure 20 is provided with a bottom-to-top tapering capillary cone 23 at the position corresponding to the accelerating circulation structure 30. The center of the accelerating circulation structure 30 is located at the center of the tapering capillary cone 23. The central guiding area formed by the combination of the tapering capillary cone 23 and the accelerating circulation structure 30 is a bottom-to-top tapering cavity. The bottom end of the inner wall of the heat pipe 50 is supported by the tapering capillary cone 23, forming a capillary interconnection structure.

[0034] For specific implementation examples, see Figures 1-5 The accelerating circulation structure 30 is a bottom-up constricting cone structure 31 that mimics the constricting capillary cone 23. The constricting cone 31 is arranged at the coaxial position of the constricting capillary cone 23.

[0035] The outer wall of the tapered frustum structure 31 is arranged to fit the inner wall of the tapered capillary frustum 23. The inner cavity of the tapered frustum structure 31 is the tapered cavity from bottom to top, which makes the positioning of the tapered capillary frustum 23 stable and reliable, and thus makes the position of the capillary heat pipe 50 stable and reliable.

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

[0037] The tapered cone structure 31 includes an inner structure 311 and an outer structure 312. The outer structure 312 is an adjustable structure with a bottom connection and a circumferential groove 3121 on the upper part. The inner structure 311 is a structure with a central hole 3111 and guide plates 3112 distributed around the periphery. The guide plates 3112 are fitted onto the corresponding upper protruding positioning rod 14, which makes the center position of the tapered cone structure 31 reliable and makes the outer structure 312 reliably fit against the inner wall of the tapered capillary cone 23, making the positioning and assembly fast and efficient.

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

[0039] In specific implementation, the central arrangement component is specifically a floral tooth 32, a cross-shaped pink column 33, or a plum blossom pink column 34.

[0040] In practice, the accelerating circulation structure 30 is specifically a capillary structure or a groove structure.

[0041] Its working principle is as follows: The bottom plate contacts the heat source for heat transfer. The internal medium is heated and vaporized. The heated medium gas passes through a cavity formed by the combination of a capillary cone and an accelerating circulation structure, which is closed from bottom to top. Due to the change in cross-sectional size, the speed is accelerated, thus rapidly circulating into the inner cavity of the capillary heat pipe. Finally, heat is conducted and dissipated, and the gas is cooled and liquefied. Under the action of gravity, it flows back to the heat source along the capillary heat pipe, the capillary cone, and the capillary structure of the bottom plate, where it is heated and evaporated again, repeating the cycle. Because the central guiding area formed by the combination of the capillary cone and the accelerating circulation structure is a cavity that is closed from bottom to top, the circulation rate of the internal medium is accelerated. Without increasing the number of heat pipes, it improves the heat transfer conductivity of the radiator and reduces economic costs.
