Description

Technical Field

[0001] The utility model relates to a radiator, in particular to a radiator combining heat pipes and fins. Background Art

[0002] In the prior art, a heat sink is constructed by inserting a portion of the heat pipe into the fin group, while the other portion is exposed outside the fin group and in contact with the heat source. Specifically, multiple heat pipes can be inserted into the fin group to improve heat dissipation efficiency. However, in the prior art, the locations where multiple heat pipes are inserted into the fin group are too uniform, and the insertion positions often form a straight line, resulting in the insertion positions being too dense. Under such a structure, heat will be transferred from the heat pipe to the same area on the fin group, causing the temperature of this area of ​​the fin group to be too high and not dissipated to the surrounding area. As a result, the temperature difference between the heat pipe and the fin group is also too low, making it impossible to effectively transfer heat.

[0003] In view of this, proposing a better improvement solution is an urgent problem to be solved in this industry. Utility Model Content

[0004] The main purpose of the present invention is to provide a heat sink that is used to be attached to a heat source and has a high heat dissipation efficiency.

[0009] a first penetrating section connected to one end of the middle section and penetrating the plurality of fins; and

[0010] a second penetrating section connected to the other end of the middle section and penetrating the plurality of fins;

[0011] Among them, the middle sections of the several heat pipes are arranged in parallel and side by side, the first penetrating sections of the several heat pipes are arranged in the first area of ​​the several fins and the several first penetrating sections are arranged in an interlaced manner, and the second penetrating sections of the several heat pipes are arranged in the second area of ​​the several fins and the several first penetrating sections are arranged in an interlaced manner.

[0028] First, please refer to Figures 1 to 4 The present invention provides a heat pipe radiator, which is used to attach to a heat source (not shown) to dissipate heat from the heat source. The heat pipe radiator of the present invention may include a fixing base 10, a plurality of heat pipes 20, and a plurality of fins 30.

[0029] In the first embodiment, the fixing base 10 has a surface 11 facing the heat source, and in this example, a gap is formed between the surface 11 and the heat source.

[0030] Each heat pipe 20 has a middle section 21, a first through-hole section 22, and a second through-hole section 23. The middle section 21 connects the first through-hole section 22 and the second through-hole section 23, forming a communication path, thereby allowing the working fluid to flow between the middle section 21, the first through-hole section 22, and the second through-hole section 23.

[0031] The middle section 21 of the heat pipe 20 is embedded in the fixing base 10 in parallel and side by side, and the middle section 21 is used to fit the heat source. Specifically, each middle section 21 has a contact surface 210, and the contact surface 210 is used to fit the heat source. The contact surface 210 of the middle section 21 of each heat pipe 20 is flush with each other, and in this embodiment, the contact surface 210 and the surface 11 of the fixing base 10 facing the heat source are not flush with the contact surface 210, that is, the contact surface 210 protrudes from the surface 11. Therefore, after the heat pipe 20 type radiator of the present invention is installed on the heat source, a gap is formed between the surface 11 and the heat source, but it is not limited to this. In this embodiment, the contact surfaces 210 of the middle section 21 are arranged at intervals. In other words, each contact surface 210 and the fixing base 10 together form a plurality of grooves.

[0032] The first penetration section 22 and the second penetration section 23 are respectively connected to two ends of the middle section 21 and penetrate the plurality of fins 30 .

[0033] Each fin 30 is arranged parallel and spaced apart, and may form a middle region 31, a first region 32, and a second region 33. The middle region 31 connects between the first region 32 and the second region 33. In other words, the middle region 31 of the fin 30 corresponds to the middle section 21 of the heat pipe 20, the first region 32 corresponds to the first penetration section 22 of the heat pipe 20, and the second region 33 corresponds to the second penetration section 23 of the heat pipe 20.

[0034] The first penetration section 22 is provided in the first area 32 of the fin 30, and the position where the first penetration section 22 is provided is staggered; the second penetration section 23 is provided in the second area 33 of the fin 30, and the position where the second penetration section 23 is provided is staggered. Specifically, a number of first imaginary lines L32 can be defined on the first area 32, and a number of second imaginary lines L33 can be defined on the second area 33. The first imaginary lines L32 and the second imaginary lines L33 are perpendicular to the middle section 21 of the heat pipe 20. The first imaginary lines are parallel and spaced apart, and the first penetration sections 22 of adjacent heat pipes 20 are provided on different first imaginary lines L32 on the first area 32, thereby forming a staggered structure. Similarly, the second imaginary lines are parallel and spaced apart, and the second penetration sections 23 of adjacent heat pipes 20 are provided on different second imaginary lines L33 on the second area 33, thereby forming a staggered structure.

[0035] Please refer to Figure 5 . In the second embodiment of the present invention, the contact surfaces 210A of the middle sections 21A of the heat pipes 20A are adjacent to each other, so no gap is formed therebetween. In addition, the surface 11A of the fixing seat 10A facing the heat source can also be flush with the contact surface 210A, so when the heat pipe type radiator of the present invention is engaged with the heat source, the contact surface 210A of the heat pipe 20 and the surface 11A of the fixing seat 10A facing the heat source can both be attached to the heat source. In addition, the middle sections 21A can also be adjacent to each other side by side so that the contact surfaces 210A are connected to form a continuous surface, or further, the contact surface 210A and the surface 11A of the fixing seat 10A facing the heat source can also form a continuous surface together.

[0036] In summary, the present invention distributes the heat pipes 20 through the fins 30 in a staggered arrangement. This prevents heat from being concentrated in one location on the fins 30, but rather distributes it evenly across the fins 30. This increases the temperature difference between the heat pipes 20 and the fins 30, improving heat dissipation efficiency. Furthermore, the flush contact surface 210 formed on the heat pipes 20 allows them to directly contact the heat source, reducing thermal resistance and also improving heat dissipation efficiency.

[0037] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modifications to the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
