Description

Technical field:

[0002] Fin heat sinks are widely used in electronic devices and industrial machinery to improve heat dissipation efficiency by increasing surface area and promoting air flow. Fin heat sinks are usually made of metal materials such as aluminum or copper because these materials have good thermal conductivity.

The first, second, and third portions of the heat pipe are respectively disposed through the first, second, and third fin groups, wherein the heat pipe, the first, second, and third fin groups are thermally coupled.

[0021] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0022] In this embodiment, the composite fin group 4 is placed directly opposite the heat generation area of the chip, and the heat pipe 1 passes through the contact area between the composite fin group 4 and the chip, so that the heat can not only be quickly discharged through the composite fin group 4, but also the heat pipe 1 transfers the heat to the first fin group 2 and the second fin group 4 for heat dissipation.

[0023] See Figures 1 to 6As shown, a new type of fully covered heat pipe composite fin clip radiator includes: a heat pipe 1, a first fin group 2, a second fin group 3, and a composite clip fin group 4, wherein the composite clip fin group 4 is located between the first fin group 2 and the second fin group 3, and the heat pipe 1 passes through the first fin group 2, the composite clip fin group 4 and the second fin group 3, and the composite clip fin group 4 includes a first aluminum extruded heat sink 41, an aluminum fin group 42, and a second aluminum extruded heat sink 43, wherein the aluminum fin group 42 and the second aluminum extruded heat sink 43 are sequentially plugged into the first aluminum extruded heat sink 41 and fixed by mechanical pressing or welding, and the heat pipe 1 passes through the overlapping area of the first aluminum extruded heat sink 41 and the aluminum fin group 42 and the second aluminum extruded heat sink 43. A composite clip fin group 4 is arranged in the middle of the heat pipe 1 and between the first fin group 2 and the second fin group 3, and the composite clip fin group 4 is arranged to be composed of a first aluminum extruded heat sink 41, an aluminum fin group 42, and a second aluminum extruded heat sink 43, which greatly increases the heat dissipation area. The heat pipe 1 is used to pass through the first aluminum extruded heat sink 41, the aluminum fin group 42, and the second aluminum extruded heat sink 43 at the same time, which breaks through the traditional radiator heat dissipation base plate and heat dissipation fin separate design, realizes the conduction and heat dissipation components into an integral component, reduces the system contact thermal resistance, and improves the heat carrying capacity of the radiator within the same volume space limitation.

[0024] The surfaces of the first aluminum extruded heat sink 41, the aluminum fin group 42, and the second aluminum extruded heat sink 43 are all equipped with a large number of heat dissipation fins. The aluminum fin group 42 is plugged into the center of the first aluminum extruded heat sink 41, and the back of the second aluminum extruded heat sink 43 is plugged into the aluminum fin group 42. The first and second aluminum extruded heat sinks 41, 43 are both trapezoidal in shape and symmetrically plugged together. The large number of heat dissipation fins on the surfaces of the first aluminum extruded heat sink 41, the aluminum fin group 42, and the second aluminum extruded heat sink 43 improves heat dissipation efficiency.

[0025] The top edge of the first aluminum extruded heat sink 41 is provided with a first heat pipe groove 51 for burying the heat pipe 1. The first heat pipe groove 51 extends downward along both sides of the waist. A second heat pipe groove 52 corresponding to the first heat pipe groove 51 is provided on one side of the aluminum fin group 42. The bottom edge of the second aluminum extruded heat sink 43 is provided with a third heat pipe groove 53 corresponding to the first heat pipe groove 51 and the second heat pipe groove 52. The second heat pipe groove 52 and the third heat pipe groove 53 are both located on the heat dissipation fins. The first heat pipe groove 51, the second heat pipe groove 52, and the third heat pipe groove 53 together form a heat pipe groove. When the heat pipe 1 is buried in the heat pipe groove, it can simultaneously maintain contact with the first aluminum extruded heat sink 41, the aluminum fin group 42, and the second aluminum extruded heat sink 43, thereby achieving rapid heat dissipation. The heat dissipation fins on the first aluminum extruded heat sink 41, the aluminum fin group 42, and the second aluminum extruded heat sink 43 are used to achieve efficient heat dissipation, while solving the high thermal resistance disadvantage of the original multi-device combination design.

[0026] The top surface of the composite fin group 4 is provided with a plurality of TIM materials 6 . The middle portion of the heat pipe 1 is arched and passes through the top surface of the composite fin group 4 flush with the top surface, and the TIM material 6 is spread flat on the composite fin group 4 and the heat pipe 1 .

[0027] The surface of the composite fin clip group 4 is provided with a heat pipe groove for burying the heat pipe 1. The heat pipe 1 is laid in the heat pipe groove and processed on the top surface of the composite fin clip group 4 to form a contact surface 10 that is flush with the top surface. The TIM material 6 is laid flat on the top surface of the composite fin clip group 4 and the contact surface 10 of the heat pipe 1. By bending the middle portion of the heat pipe 1 and laying it flush with the top surface of the composite fin clip group 4, and using the TIM material 6 to lay flat on the top surface of the composite fin clip group 4 and the contact surface 10 of the heat pipe 1, the surface of the chip is simultaneously in contact with the heat pipe 1 and the composite fin clip group 4, greatly increasing the heat conduction area, so that the heat generated by the chip is transferred to the heat pipe 1 and the composite fin clip group 4, and improving the heat conduction efficiency.

[0028] At least two reinforcement brackets 7 are provided on the bottom surfaces of the first fin group 2, the second fin group 3, and the composite clip fin group 4. The reinforcement brackets 7 connect the first fin group 2, the second fin group 3, and the composite clip fin group 4 in series by welding. A small component heat dissipation base plate 8 is provided on the top surface of the first fin group 2.

[0029] In summary, the present invention includes: a group of composite clip fins, two groups of single-type aluminum fins, and a heat pipe 1, a small component heat dissipation base plate 8, a TIM material 6, and an aluminum reinforcement bracket 7 connected between the single-type fin group and the composite clip fin. Among them, the new composite clip fin is formed by combining two or more components through mechanical extrusion or metal welding to form a composite clip fin. In this embodiment, the composite clip fin group 4 is composed of a first aluminum extruded heat sink 41, an aluminum fin group 42, and a second aluminum extruded heat sink 43. The two groups of single-type aluminum fins are the first fin group 2 and the second fin group 3. In the present invention, the composite clip fin group 4 combines a group of single-type aluminum fins 42 with two groups of integrally formed aluminum extruded heat sinks (the first aluminum extruded heat sink 41 and the second aluminum extruded heat sink 43) through metal welding to form a new full-coverage heat pipe composite clip fin group radiator. The composite clip fin group 4 is placed in the corresponding chip heating area and three groups of devices are combined in it to form a heat pipe groove of corresponding size through mechanical processing. The heat pipe 1 is then welded, machined and polished to directly contact the chip, and the heat pipe 1 is welded with the other two groups of fins (the first fin group 2 and the second fin group 3) to form a high-performance radiator.

[0030] In this utility model, the use of the composite clip fin group 4 breaks through the design of the combination of multiple components of the radiator heat dissipation base plate, fins, and heat pipes, solves the high thermal resistance disadvantage of the original design of the combination of multiple components, and makes the radiator have the following advantages:

[0031] First, compared to the original single aluminum fin, the new full-coverage heat pipe composite clip fin is composed of two sets of aluminum extrusion components (a first aluminum extrusion heat sink 41 and a second aluminum extrusion heat sink 43). Both heat sinks have a large number of heat dissipation fins on their surfaces, increasing the heat dissipation area.

[0032] Secondly, the new type of full-coverage heat pipe composite clip fins have been specially processed and broken through to provide 100% coverage of the heat pipe bending area, which greatly improves the utilization rate of the heat pipe and enhances the overall temperature uniformity and heat transfer efficiency of the radiator.

[0033] Third, the new fully covered heat pipe composite clip fin design breaks through the original radiator heat dissipation base plate and the separate heat dissipation fin design, integrating the conduction and heat dissipation components into a single device, reducing the system contact thermal resistance and improving the heat carrying capacity of the radiator within the same volume space limitation.

[0034] Fourthly, the new full-coverage heat pipe composite clip fins are in direct contact with the chip surface, and the heat generated by the chip is transferred to the heat pipe and composite clip fin combination, which improves the heat conduction efficiency.

[0035] In summary, the application of the novel composite fin heat sink in the present invention meets the demand of today's electronic products for high-performance, high-frequency, high-speed and lightweight heat sinks, and has a very high cost-effectiveness, making the present invention highly competitive in the market.

[0036] Of course, the above description is only a specific embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. Any equivalent changes or modifications made based on the structure, features and principles described in the scope of the patent application of the present invention should be included in the scope of the patent application of the present invention.
