Description

Technical Field

[0001] This utility model relates to the field of heat dissipation equipment technology, specifically to a multi-purpose high-efficiency heat sink. Background Technology

[0002] In the field of electronic equipment and high-power appliances, heat dissipation performance directly affects the stability and lifespan of the equipment. Traditional finned heat sinks mostly adopt a planar array structure, which limits the heat dissipation area and cannot make full use of space. The heat concentration leads to low heat dissipation efficiency. At the same time, due to the dense arrangement of heat-conducting elements, heat accumulation is easy to form, affecting the heat dissipation effect. The single copper tube heat conduction design cannot meet the heat dissipation requirements of high-power equipment, and the structural compatibility is poor: the fixed shape of the heat dissipation module is difficult to adapt to heat-generating devices of different sizes. When replacing equipment, the entire heat sink must be replaced, which is costly. In addition, most heat sinks adopt a rectangular structure, which causes airflow turbulence and large air pressure loss when used with fans.

[0003] Therefore, designing a high-efficiency radiator that combines large heat dissipation area, uniform heat distribution, optimized airflow, and wide applicability has become the key to solving the heat dissipation problem of high-power equipment. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes a multi-purpose high-efficiency radiator that uses a combination of three-dimensional heat dissipation components and heat conduction components to form a high-efficiency heat dissipation device with a three-dimensional heat dissipation structure, staggered heat conduction design, and optimized airflow.

[0005] The technical solution adopted by this utility model is: a multi-purpose high-efficiency radiator, including a heat dissipation component and a heat conduction component; the heat dissipation component includes a heat dissipation concave block and a heat dissipation protrusion with concave and convex structures respectively in longitudinal cross sections, so that the heat dissipation concave block and the heat dissipation protrusion can be assembled into one piece; the inner peripheral wall of the heat dissipation concave block is provided with multiple inner stepped portions arranged vertically, and the outer peripheral wall of the heat dissipation protrusion is provided with outer stepped portions arranged one-to-one with the inner stepped portions, and a heat conduction space is formed between the outer stepped portions and the inner stepped portions; each heat conduction coil is provided with a heat conduction end, and the heat conduction ends on each heat conduction coil are staggered on the radial plane of the heat dissipation component, and each heat conduction coil is also fixedly connected to a heat conduction base, and the surface of the heat conduction base is provided with a heat conduction surface.

[0006] In this technical solution, the radiator consists of a heat-conducting part and a heat-dissipating part. The heat-conducting base of the heat-conducting part is installed at the location of the equipment that needs heat dissipation. Heat is conducted to the heat dissipation component through each heat-conducting coil for sufficient heat dissipation. After the heat dissipation concave and convex blocks of the heat dissipation component are assembled, the heat-conducting coil is installed in the heat-conducting space. The heat dissipation concave and convex blocks completely cover the outside of the heat-conducting coil to form a three-dimensional heat dissipation space, which can significantly increase the heat dissipation area and space. The heat carried by each heat-conducting coil can be transferred to the heat dissipation concave and convex blocks through the heat-conducting ends. Since the heat-conducting ends are arranged in an alternating manner, the heat can be fully dispersed so that the heat is dissipated from different directions of the heat dissipation concave and convex blocks. The three-dimensional heat dissipation structure can improve the heat dissipation effect.

[0007] Preferably, the heat dissipation recess and heat dissipation protrusion include a plurality of heat dissipation fins arranged in a circular pattern, and the edges of the heat dissipation fins are provided with fastening and fixing parts so that adjacent heat dissipation fins can be locked together and fixed, and a heat dissipation gap is formed between adjacent heat dissipation fins.

[0008] Preferably, the surfaces of the outer and inner stepped portions opposite each other are provided with assembly grooves for accommodating the heat-conducting coil.

[0009] Preferably, the heat-conducting base includes an upper and lower mounting block and a contact base, with a plurality of fixing grooves for fixing the heat-conducting coil between the mounting block and the contact base, and the heat-conducting surface is located on the bottom surface of the contact base.

[0010] Preferably, the fixing block has fixing parts at both ends, and bolts with springs are installed on the fixing parts.

[0011] Preferably, the heat dissipation components are symmetrically arranged along both sides of the heat conduction base, and a fan module coaxially arranged with the heat dissipation components is provided between the two heat dissipation components and on the side opposite to the two heat dissipation components.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model forms a multi-layer heat-conducting space through the interlocking of concave and convex parts, breaking through the area limitation of traditional planar heat dissipation; it is a significant improvement over traditional planar heat dissipation structures.

Detailed Implementation

[0024] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0025] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0026] like Figures 1 to 5As shown in the figure, a specific embodiment of this utility model provides a multi-purpose high-efficiency radiator, including a heat dissipation component and a heat conduction component; the heat dissipation component includes a heat dissipation concave block 100 and a heat dissipation protrusion 200 with concave and convex longitudinal cross sections respectively, so that the heat dissipation concave block 100 and the heat dissipation protrusion 200 can be assembled into one piece; the inner peripheral wall of the heat dissipation concave block 100 is provided with multiple inner stepped portions 110 arranged vertically, and the outer peripheral wall of the heat dissipation protrusion 200 is provided with outer stepped portions 210 arranged one-to-one with the inner stepped portions 110, the outer stepped portions 210... A heat-conducting space is formed between the outer step 210 and the inner step 110; the heat-conducting assembly includes a heat-conducting base 300 and a plurality of heat-conducting coils 400. Each heat-conducting coil 400 can be inserted into the heat-conducting space between the corresponding outer step 210 and the inner step 110. Each heat-conducting coil 400 is provided with a heat-conducting end 410. The heat-conducting ends 410 on each heat-conducting coil 400 are staggered on the radial plane of the heat dissipation assembly. Each heat-conducting coil 400 is also fixedly connected to the heat-conducting base 300. The surface of the heat-conducting base 300 is provided with a heat-conducting surface.

[0027] like Figures 1 to 5 As shown, with the above configuration, the radiator consists of a heat-conducting part and a heat-dissipating part; the heat-dissipating recess 100 and heat-dissipating protrusion 200 are detachably assembled through a stepped structure, and an annular heat-conducting space is formed between the inner and outer stepped parts; when the equipment is installed and used, the heat-conducting seat 300 of the heat-conducting part is installed at the location of the equipment that needs heat dissipation, and the heat dissipation area of ​​the equipment is in contact with the heat-conducting surface. The heat is conducted to the heat dissipation component through each heat-conducting coil 400 for sufficient heat dissipation. After the heat-dissipating recess 100 and heat-dissipating protrusion 200 of the heat dissipation component are assembled, the heat-conducting recess 100 and heat-dissipating protrusion 200 are connected to the heat-conducting surface. The heat pipe 400 is installed within the heat-conducting space. The heat-conducting area of ​​the heat pipe 400 is completely covered by the heat-dissipating recesses 100 and protrusions 200, significantly increasing the heat dissipation area and space. The heat carried by each heat pipe 400 can be transferred to the heat-dissipating recesses 100 and protrusions 200 through the heat-conducting ends 410. Because the heat-conducting ends 410 are staggered, heat concentration is avoided during heat dissipation, which helps to fully disperse heat, allowing it to dissipate from different directions on the heat-dissipating recesses and protrusions. This three-dimensional heat dissipation structure improves the heat dissipation effect. It can be used in products with high heat generation, such as computer CPUs and high-power lighting fixtures.

[0028] like Figure 1 As shown, in practical applications, the inner peripheral wall of the heat dissipation recess 100 is provided with 3-5 vertically arranged inner stepped portions 110, and the outer peripheral wall of the heat dissipation protrusion 200 is provided with a corresponding number of outer stepped portions 210. After each heat conduction coil 400 is installed in the heat conduction space, the heat conduction coil 400 is fixed to the heat dissipation structure by welding. At the same time, the opposing surfaces of the outer stepped portions 210 and the inner stepped portions 110 are provided with assembly grooves 520 for accommodating the heat conduction coil 400. The assembly grooves 520 can stably assemble the heat conduction coil 400 with the heat dissipation structure.

[0029] like Figure 2 As shown, to improve heat dissipation efficiency, in this embodiment, the heat dissipation concave block 100 and the heat dissipation protrusion 200 include a plurality of heat dissipation fins 500 arranged in a circular pattern. Each heat dissipation fin 500 has a snap-fit ​​fixing part 510 on its edge, allowing adjacent heat dissipation fins 500 to snap into each other and form a heat dissipation gap between them. Thus, each heat dissipation fin 500 has a snap-fit ​​fixing part 510 (such as an L-shaped buckle) on its edge to form a fixing structure. After adjacent heat dissipation fins 500 snap into place, a heat dissipation gap of 2-5mm is formed. The overall heat dissipation area is significantly increased compared to traditional planar heat dissipation structures. In practical applications, the heat dissipation fins 500 adopt an aluminum sheet structure.

[0030] like Figure 4 As shown, the heat-conducting base 300 provided in this embodiment includes a fixing block 320 and a contact base 310 arranged vertically. Several fixing grooves for fixing heat-conducting coils 400 are provided between the fixing block 320 and the contact base 310. One end of the heat-conducting coil 400 connected to the heat-conducting base 300 is inserted into the fixing groove, and the heat-conducting surface is located on the bottom surface of the contact base. Thus, the fixing grooves ensure a stable connection between the heat-conducting coil 400 and the heat-conducting base 300. The fixing block 320 has fixing parts at both ends, and bolts 330 with springs are installed on the fixing parts. The entire device can be installed on a heat dissipation device via the fixing parts, and heat-generating devices of different thicknesses can be installed using the bolts 330. The springs achieve elastic compression with the heat-generating device, ensuring a tight fit between the heat-conducting surfaces. To improve heat conduction efficiency, the contact base 310 is made of copper, and the fixing block 320 is made of aluminum.

[0031] like Figure 5 As shown, the heat dissipation components are symmetrically arranged on both sides of the heat conduction base 300. A fan module coaxial with the heat dissipation components is located between the two heat dissipation components and on the opposite side. This allows the fan module 600 to form an optimized airflow channel with axial intake and radial exhaust. The use of circular heat dissipation components in conjunction with the coaxial fan significantly reduces air pressure loss compared to traditional square planar heat dissipation structures, further improving heat dissipation efficiency. Due to the symmetrical arrangement of the heat dissipation components, the heat conduction coil 400 can extend symmetrically at 180° after passing through the heat conduction base 300, ensuring temperature field uniformity. Furthermore, after assembling the fan module, the entire heat dissipation assembly can also be fitted with an outer shell structure, which will not be elaborated here.

[0032] During assembly: the heat-conducting coil is embedded into the fixing groove of the heat-conducting base to ensure good contact between the heat-conducting coil and the heat-conducting base; the heat dissipation concave and convex blocks are respectively fitted onto the heat-conducting ends of the heat-conducting coil from both sides, so that the outer stepped part and the inner stepped part are fitted together, and the heat-conducting end is embedded in the assembly groove; fan modules are installed on both sides of the heat dissipation assembly to ensure that the fan axis is coaxial with the heat dissipation assembly; the heat sink is fixed to the heat-generating equipment by spring bolts, and the spring compression is adjusted to make the heat-conducting surface tightly fit the surface of the equipment.

[0033] The working principle is as follows: the heat-conducting surface of the heat-conducting base 300 is attached to the heat-generating device (such as the CPU surface), and the heat-conducting coil 400 conducts heat to the heat dissipation component. The heat is transferred to the heat dissipation concave block and heat dissipation convective block through the heat-conducting space. The annular heat sink array increases the convection heat transfer area. When the air flows through the heat dissipation gap, it carries away the heat. Under the action of the fan, a heat dissipation airflow is generated, forming an axial air intake and radial air exhaust airflow path to achieve further active heat dissipation.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
