Description

Technical Field

[0001] The utility model relates to the technical field of skived-tooth radiators, in particular to a closed skived-tooth radiator. Background Art

[0002] Skived-tooth heat sinks are an integrated heat sink formed by shaving layers of fins from a single block of material, such as aluminum or copper. The integrated structure of the base and fins effectively avoids interfacial impedance issues and is widely used in the industry. However, the thin and tall fins of skived-tooth heat sinks can easily shake, deform, and bend under external forces, affecting product performance. To address this issue, industry professionals have proposed a number of fin protection methods.

[0003] For example, the Chinese utility model patent application, "A Skived-tooth Radiator," with publication number CN212082117U, adds a fin fixing plate to the existing skived-tooth radiator. This plate secures the entire set of fins together to form a single structure, increasing the fin strength and effectively preventing them from bending under external forces. However, the addition of the fin fixing plate to the skived-tooth radiator reduces the radiator's heat dissipation capacity due to the different materials and the resulting thermal resistance, making it unsuitable for high heat dissipation requirements. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings, the present invention aims to provide a technical solution that can solve the above-mentioned problems.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a closed skiving radiator, comprising a base and a heat dissipation assembly located on the top of the base, the heat dissipation assembly comprising a substrate integrally formed on the top of the base, the substrate being suitable for being skived by a skiving knife to form a plurality of heat dissipation fins spaced front and back; the heat dissipation assembly also comprises a closing portion integrally formed on the top of the base, the closing portion forming a horizontal enclosure for the substrate; wherein a skiving retraction position is formed between the rear frame portion of the closing portion and the substrate, and a skiving process groove is formed between the front frame portion of the closing portion and the substrate.

[0006] As a further solution of the present invention, the closed portion is higher than the heat dissipation fins formed after the base plate is scraped.

[0007] As a further solution of the present invention: the skiving process groove has a first extension groove extending leftward to the left frame portion of the recessed closed portion, and a second extension groove extending rightward to the right frame portion of the recessed closed portion.

[0008] As a further solution of the present invention: the skiving tooth retraction position has a skiving tooth guide wall which is inclined toward the top of the rear frame portion of the closing portion.

[0009] As a further solution of the present invention: the inclination of the shovel tooth guide wall is 30°-50°.

[0010] As a further solution of the present invention: the left side of the shovel tooth guide wall has a first disconnection opening disconnected from the left frame portion of the closing portion, and the right side of the shovel tooth guide wall has a second disconnection opening disconnected from the right frame portion of the closing portion.

[0011] Compared with the prior art, the beneficial effect of this technical solution is: when the substrate is suitable for being scraped by a scraping knife to form a plurality of heat dissipation fins spaced front and back, the closed portion forms a corresponding protection for the heat dissipation fins, so that the heat dissipation fins are not easily damaged or bent, and the closed portion is integrally formed on the top of the base, and the closed portion also constitutes a heat dissipation component with high thermal conductivity efficiency. While satisfying the protection of the heat dissipation fins, it effectively ensures that this closed skived-tooth radiator has good heat dissipation capacity.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-3 A closed skived-tooth heat sink comprises a base 1 and a heat sink assembly located on top of the base 1. The base 1 is made of a material with good heat dissipation performance, such as copper or aluminum. That is, the base 1 itself has good heat dissipation and thermal conductivity, so that it can transfer its own heat to the heat sink assembly on top, thereby achieving better heat dissipation.

[0025] The heat dissipation assembly includes a base plate integrally formed on top of a base 1. This base plate is adapted to be scraped by a scraping blade to form a plurality of heat dissipation fins 2 spaced apart from one another. The heat dissipation fins 2 can be arranged vertically or at a certain inclination in the front-to-back direction. These fins 2 significantly increase the heat dissipation area. Furthermore, the fins 2 and base 1 are integrally formed, eliminating any additional thermal resistance and providing high thermal efficiency.

[0026] The heat dissipation assembly also includes a sealing portion 3 integrally formed on the top of the base 1, forming a horizontal enclosure around the substrate. A skiving retraction position 5 is formed between the rear frame 3a of the sealing portion and the substrate to prevent the skiving cutter from damaging the rear frame 3a of the sealing portion during the skiving operation. A skiving groove 4 is formed between the front frame 3b of the sealing portion and the substrate.

[0027] When the substrate is suitable for being scraped by a scraping knife to form a plurality of heat dissipation fins 2 spaced apart in the front and rear, the closing portion 3 forms a corresponding protection for the heat dissipation fins 2, so that the heat dissipation fins 2 are not easily damaged or bent, and the closing portion 3 is integrally formed on the top of the base 1. The closing portion 3 also constitutes a heat dissipation component with high thermal conductivity efficiency. While satisfying the protection of the heat dissipation fins 2, it effectively ensures that the closed skived-tooth radiator has good heat dissipation capacity.

[0028] Preferably, the closed portion 3 is higher than the heat dissipation fins 2 formed after the substrate is scraped.

[0029] In the embodiment of the present invention, the skived groove 4 has a first extension groove 401 extending leftward to the left frame portion 3c of the concave closed portion, and a second extension groove 402 extending rightward to the right frame portion 3d of the concave closed portion.

[0030] In the embodiment of the present invention, the skiving retraction position 5 has a skiving guide wall 501 that is inclined toward the top of the rear frame portion 3a of the closed portion.

[0031] Preferably, the inclination of the shovel tooth guide wall 501 is 30°-50°.

[0032] Furthermore, the left side of the shovel guide wall 501 has a first disconnection opening 502 disconnected from the left frame portion 3c of the closed portion, and the right side of the shovel guide wall 501 has a second disconnection opening 503 disconnected from the right frame portion 3d of the closed portion.

[0033] like Figure 4 As shown, the closed skived radiator 100 without skiving can be fixed on a workpiece fixture 6 that can move forward and backward, and cooperated with a skiving knife 7 that can move up and down to perform skiving operations on the substrate, and multiple heat dissipation fins 2 are sequentially skived from front to back to obtain the closed skived radiator.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
