Abstract
Description
Technical Field
[0001] This utility model relates to the field of radiator technology, and more specifically, to a cold-forged radiator with multi-faceted heat dissipation fins. Background Technology
[0002] As a commonly used heat dissipation device in electronic equipment, the core function of a heat sink is to quickly dissipate heat generated by a heat source through heat conduction and air convection. Traditional heat sinks typically consist of a fan, heat pipes, and heat dissipation fins. The heat dissipation fins are often integrally formed using a cold forging process to improve structural strength and thermal conductivity. The cold forging process allows the fins to form a multi-faceted structure, significantly increasing the heat dissipation area and enhancing airflow turbulence, thereby optimizing heat dissipation performance.
[0003] Currently, traditional heat sinks use a fan to blow air over the fins, transferring heat from the hot liquid inside the heat pipes to the fins. However, the contact time between the airflow and the fins is relatively short, limiting heat dissipation efficiency. Therefore, we propose a cold-forged heat sink with multi-faceted cooling fins. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a cold-forged radiator with multi-faceted heat dissipation fins to solve the technical problems of short contact time between airflow and fins and limited heat dissipation efficiency in traditional radiators.
[0005] To solve the above technical problems, the present invention provides the following technical solution: a cold-forged heat sink with multi-faceted heat dissipation fins, including a housing, a fan arranged at the front end inside the housing, a heat dissipation mechanism arranged at the rear end inside the housing, the heat dissipation mechanism including a shell, an input pipe arranged at the upper end inside the shell, a shunt pipe A connected to one end of the input pipe, a heat dissipation pipe connected to one end of the side of the shunt pipe A, and fin units arranged on the heat dissipation pipe;
[0006] The fin unit includes a plate arranged on a heat pipe, and a cavity is formed through the plate. Multiple guide plates are arranged at intervals on both sides of the cavity, and the multiple guide plates are all in an inclined structure shape.
[0007] Preferably, an output pipe is arranged at the lower end of the inner casing, one end of the output pipe is connected to a shunt pipe B, and the other end of a heat dissipation pipe is connected to the side of the shunt pipe B.
[0008] Preferably, the inner sides of the outer shell are provided with through holes, and a diversion pipe A and a diversion pipe B are inserted into the holes.
[0009] Preferably, there are five heat dissipation pipes, which are arranged in a forked shape between the branch pipe A and the branch pipe B.
[0010] Preferably, the front end of the sheet has an air inlet and the rear end of the sheet has an air outlet, and the air inlet has an outwardly flared, sloping structure.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This utility model improves heat dissipation efficiency by designing a cavity structure that allows the airflow generated by the fan to pass through it and carry away the heat conducted to the heat plate by the hot liquid inside the heat pipe. By designing a guide plate structure, multiple guide plates are installed in an inclined shape on both sides of the cavity. When the airflow generated by the fan enters the cavity, it will flow back and forth between the guide plates, increasing the residence time of the air in the cavity, which is more conducive to carrying away the heat conducted to the heat plate and further optimizing the heat dissipation effect.
[0013] 2. The air inlet of this utility model adopts an outwardly expanding inclined surface structure design, which can guide the external airflow to enter the cavity more smoothly. The airflow flows back and forth in the cavity under the action of the guide plate, fully absorbs the heat of the plate, and is discharged through the air outlet, further enhancing the airflow heat exchange efficiency in the heat dissipation process and optimizing the overall heat dissipation performance.
[0014] 3. This utility model, through the design of the diversion pipe A and diversion pipe B, allows the hot liquid output from the output pipe to be evenly distributed to five heat dissipation pipes via diversion pipe A. After the hot liquid completes heat exchange within the heat dissipation pipes, diversion pipe B collects the liquid that has been dissipated from the five heat dissipation pipes and re-inputs it into the output pipe, achieving an efficient cycle of "dispersed heat dissipation - concentrated collection - retransmission" for the hot liquid. The heat dissipation pipes of this utility model are designed as five pipes, arranged in a branching structure between diversion pipe A and diversion pipe B. This layout can effectively expand the contact area between the hot liquid and the external airflow, optimize the heat dissipation effect, and at the same time ensure the stability and smoothness of the liquid diversion and collection process.

[0022] like Figures 1 to 5 As shown, the present invention relates to a cold-forged heat sink with multi-faceted heat dissipation fins, including a housing 1, a fan 2 arranged at the front end inside the housing 1, and a heat dissipation mechanism 3 arranged at the rear end inside the housing 1. The heat dissipation mechanism 3 includes a housing 301, an input pipe 302 arranged at the upper end inside the housing 301, a shunt pipe A303 connected to one end of the input pipe 302, a heat dissipation pipe 304 connected to the side of the shunt pipe A303, and a fin unit 305 arranged on the heat dissipation pipe 304.
[0023] The fin unit 305 includes a fin body 3051 arranged on the heat sink 304. A cavity 3052 is formed through the fin body 3051. Multiple guide plates 3053 are arranged at intervals on both sides of the cavity 3052, and all guide plates 3053 are inclined. This invention improves heat dissipation efficiency by designing the cavity 3052 structure so that the flowing gas generated by the fan 2 can pass through it and carry away the heat conducted from the hot liquid in the heat sink 304 to the fin body 3051. By designing the guide plate 3053 structure, the multiple guide plates 3053 are installed in an inclined shape on both sides of the cavity 3052. When the flowing gas generated by the fan 2 enters the cavity 3052, it will flow back and forth between the guide plates 3053, increasing the residence time of the gas in the cavity 3052, which is more conducive to carrying away the heat conducted to the fin body 3051.
[0024] In an embodiment of this invention, an output pipe 306 is arranged at the lower end of the inner casing 301. One end of the output pipe 306 is connected to a diversion pipe B307, and the other end of a heat dissipation pipe 304 is connected to the side of the diversion pipe B307. By designing the diversion pipes A303 and B307, the hot liquid output from the output pipe 306 can be evenly distributed to the five heat dissipation pipes 304 via the diversion pipe A303. After the hot liquid completes heat exchange within the heat dissipation pipes 304, the diversion pipe B307 collects the dissipated liquid from the five heat dissipation pipes 304 and re-inputs it into the output pipe 306, achieving a highly efficient cycle of "dispersed heat dissipation—collection—retransmission" of the hot liquid.
[0025] In an embodiment of this utility model, holes are provided through both sides of the interior of the outer casing 301, and a shunt pipe A303 and a shunt pipe B307 are inserted into the holes. The holes in this utility model allow the shunt pipe A303 and the input pipe 302 and heat dissipation pipe 304 connected at both ends, and the shunt pipe B307 and the output pipe 306 and heat dissipation pipe 304 connected at both ends to be stably installed inside the outer casing 301, thus providing a supporting effect.
[0026] In this embodiment of the invention, five heat dissipation pipes 304 are provided, arranged in a forked blood vessel shape between the diversion pipe A303 and the diversion pipe B307. The design of five heat dissipation pipes 304 arranged in a forked blood vessel structure between the diversion pipe A303 and the diversion pipe B307 effectively expands the contact area between the hot liquid and the external airflow, optimizes the heat dissipation effect, and ensures the stability and smoothness of the liquid diversion and collection process.
[0027] In this embodiment of the invention, an air inlet 3054 is provided at the front end of the sheet 3051, and an air outlet 3055 is provided at the rear end of the sheet 3051. The air inlet 3054 has an outwardly flared, sloping structure. The outwardly flared, sloping structure of the air inlet 3054 of this invention guides external airflow to enter the cavity 3052 more smoothly. The airflow flows back and forth within the cavity 3052 under the action of the guide plate 3053, fully absorbing the heat from the sheet 3051 before being discharged through the air outlet 3055, further enhancing the airflow heat exchange efficiency during the heat dissipation process and optimizing the overall heat dissipation performance.
[0028] Working Principle: This embodiment provides a cold-forged heat sink with multi-faceted heat dissipation fins. During use, the operator needs to connect an external power supply to the device and control its operation via a controller. The operator pumps the hot liquid to be cooled into the input pipe 302. Once inside the input pipe 302, the hot liquid is transported to the distribution pipe A303, and then through the distribution pipe A303 to the interior of multiple heat dissipation pipes 304. The hot liquid entering the heat dissipation pipes 304 conducts its heat to the fins 3051 within the fin units 305. At this time, the fan 2 rotates. The flowing gas generated during operation flows around the plate 3051. When the flowing gas is guided into the cavity 3052 by the outward expansion slope structure of the air inlet 3054, the flowing gas will flow back and forth between multiple guide plates 3063. This increases the time the flowing gas spends in the cavity 3052, allowing the flowing gas to carry away more heat from the plate 3051. Finally, the flowing gas that has carried away the heat is discharged through the air outlet 3055, while the cooled liquid is collected and transferred to the output pipe 306 through the diversion pipe B307. Finally, the cooled liquid is transferred to the equipment to be used through the output pipe 306.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
