[0002] With the rapid development of electronic devices, the heat generated by the devices during operation continues to increase, and how to effectively dissipate heat has become an important technical issue.

[0003] In existing electronic equipment cooling technology, heat pipes are widely used in skived-tooth heat sinks due to their efficient thermal conductivity. However, heat pipes have a limited design width range, typically no wider than 16mm, and a narrow operating temperature range, typically between -30°C and 150°C. Furthermore, the use of heat pipes can increase the weight of the equipment. Therefore, it is necessary to develop a new skived-tooth heat sink structure to address these issues while simultaneously achieving long-distance heat transfer and efficient heat dissipation. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides an aluminum heat conducting plate skived tooth radiator structure, which achieves wider temperature adaptability and higher thermal conductivity efficiency by adopting aluminum heat conducting plates instead of heat pipes in the skived tooth radiator.

[0008] Furthermore: a steam channel is formed in the direction of the evaporation zone toward the condensation zone, and a plurality of strip-shaped capillary layers are provided in each group of steam channels separated by the plurality of air channel partitions.

[0019] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0020] like Figure 1 and Figure 2 As shown, the utility model provides a skived-tooth radiator structure with an aluminum heat conducting plate 2, comprising a skived-tooth radiator body and an aluminum heat conducting plate 2, wherein the skived-tooth radiator body comprises a substrate 1, wherein one surface of the substrate 1 is provided with a plurality of plate grooves 11, and the other surface is a heat dissipation surface; a plurality of the aluminum heat conducting plates 2 are respectively arranged in a plurality of plate grooves 11, and a plurality of fins 3 for quickly dissipating heat from the substrate 1 are arranged in parallel on the heat dissipation surface.

[0021] Specifically, the aluminum heat conducting plate 2 is in the shape of an elongated strip. When the aluminum heat conducting plate 2 is embedded in the plate groove 11 and press-fitted, the upper surface of the aluminum heat conducting plate 2 is flush with the surface of the substrate 1 .

[0022] like Figures 3 and 4 As shown, the aluminum heat conducting plate 2 has a closed working chamber 21 inside, and the working chamber 21 is filled and encapsulated with a working fluid that undergoes a phase change after being heated. The aluminum heat conducting plate 2 is attached to the heat source, and the area of ​​the end of the aluminum heat conducting plate 2 attached to the heat source matches the heat dissipation area required by the heat source. The end of the working chamber 21 close to the heat source is the evaporation area 211, and the other end is the condensation area 212, and a steam channel 213 is formed along the evaporation area 211 toward the condensation area 212.

[0023] Furthermore, the inner wall of the working chamber 21 is provided with a capillary structure in contact with the working fluid. During operation, the working fluid absorbs heat at the heat source and vaporizes to form high-temperature steam. The high-temperature steam carries the heat through the steam channel 213 and enters the condensation zone 212. After encountering cold, it gradually condenses into liquid, releasing heat. The condensed liquid returns to the heat source through the capillary structure on the inner wall of the working chamber 21, completing one cycle and providing low-temperature working fluid for the next cycle, thereby achieving the purpose of long-distance heat transmission and heat dissipation.

[0024] Furthermore, in order to improve the efficiency of long-distance heat transmission, in this embodiment, a plurality of air duct partitions 22 extending from the evaporation area 211 to the condensation area 212 are provided inside the aluminum heat conducting plate 2. The air duct partitions 22 divide the working chamber 21 into multiple groups of steam channels 213. This structure greatly improves the longitudinal heat diffusion performance of the aluminum heat conducting plate 2, and can transmit heat and perform heat exchange over longer distances.

[0025] Furthermore, the capillary structure includes a strip capillary layer 23 protruding from the inner wall of the working chamber 21 toward the steam channel 213, and the strip capillary layer 23 extends along the evaporation area 211 toward the condensation area 212, and each group of steam channels 213 is provided with multiple groups of strip capillary layers 23, so that the capillary force in each steam channel 213 is increased, thereby improving the efficiency of the working fluid circulation and achieving better heat dissipation effect.

[0026] In another embodiment, the aluminum heat conducting plate 2 is provided with a rounded corner structure 24 along the circumferential side. The rounded corner structure 24 cooperates with the guiding inclined surface of the plate groove 11 to enhance the stability of the aluminum heat conducting plate 2 in the plate groove 11. At the same time, the rounded corner structure 24 can effectively disperse the stress received by the aluminum heat conducting plate 2 and extend its service life.

[0027] When the aluminum heat conducting plate 2 is installed, chemical nickel is plated in the plate groove 11, and the aluminum heat conducting plate 2 is embedded and installed by soldering with solder paste, which saves processing technology, saves processing time, and reduces nickel plating costs.

[0028] The aluminum heat conducting plate 2 is made of aluminum. Compared to traditional heat pipes, it is lighter and more structurally robust, contributing to lightweight equipment. Furthermore, compared to existing heat pipes, the aluminum heat conducting plate 2 can be designed to be up to 300 mm wide, better meeting the need for a large heat source dissipation area. A single set of aluminum heat conducting plates 2 can replace multiple sets of heat pipes. Furthermore, compared to existing heat pipes, the working fluid in the aluminum heat conducting plate 2 has a wider operating range, operating within a temperature range of -60°C to 150°C. By replacing heat pipes with aluminum heat conducting plates in skived-tooth radiators, a wider temperature range and higher thermal efficiency are achieved.

[0029] The number, location, and size of the aluminum heat conducting plates 2 and plate slots 11 are determined by the number and location of the heat sources and the required heat dissipation area. By embedding the aluminum heat conducting plates 2 in the corresponding plate slots 11 of the base plate 1, heat is rapidly diffused from the evaporation area 211 of the aluminum heat conducting plates 2 to the condensation area 212, and then spread across the entire surface of the base plate 1. The heat is then removed by the fins 3 on the heat dissipation surface of the base plate 1. The multiple plate slots 11 on the base plate 1 can meet the heat dissipation needs of multiple heat sources.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
