Description

radiator structure

technical field

The utility model relates to a heat sink structure, in particular to a structure in which several radiating fins arranged in a vertical and horizontal staggered manner are arranged above a heat conduction base.

Background technique

Due to the rapid progress of modern computer information, the working speed of its central processing unit is increasing day by day, and the accompanying high temperature must rely on the cooling effect of high-efficiency radiators and fans to maintain normal operating temperature.

For a general heat sink a (as shown in Figure 10), it is extruded by aluminum extrusion, but the heat sink a made by aluminum extrusion has its fins b equally spaced in one direction Arrangement, when an external fan is combined above the heat sink a, the airflow generated by the fan is divided by each fin b, and can only flow between each fin b. Due to the limited flow space of the hot air, a large amount of hot air generated by the central processing unit still accumulates under the fin b and cannot form heat exchange with the cooler air molecules above the fin b to achieve the effect of heat dissipation.

Please refer to Fig. 11, in order to solve the above-mentioned problems caused by conventional heat sinks, the industry uses a thin metal sheet to continuously bend it into several heat dissipation fins c, the top of the fins c is set in an inverted V shape, and A thin slit d is cut at the position, so that the airflow generated by the fan e can flow quickly between the fins c. Although the above-mentioned structure can increase the heat dissipation area of the heat dissipation fin c, the space for hot air to flow is still limited, and the slit gap d at the top of the fin c can only allow a small amount of space to pass through. When the processing unit operates at high speed and generates high temperature, it still cannot effectively exchange the hot and cold molecules in the air to discharge the hot air, and the heat dissipation effect is not ideal.

Detailed ways

Please refer to the first embodiment of the radiator structure 1 of the present invention shown in FIGS. Fins 3, these heat dissipation fins 3 are elongated sheets with rounded corners on four sides (also can be square columns, elongated trapezoidal blocks). The plurality of heat dissipation fins 3 includes a first fin group 4 and a second fin group 5, and the two fin groups (4, 5) respectively include several heat dissipation fins 3 arranged in a rectangular array. The heat dissipation fins 3 of the fin group 4 and the second fin group 5 are alternately arranged.

Please refer to FIG. 4 and FIG. 5 , a fan 6 is connected to the top of the plurality of cooling fins 3 of the present invention, and a central processing unit 7 is connected to the bottom of the heat conduction base 2 . When the central processing unit 7 runs at a high speed, its heat is conducted upwards through the heat conduction base 2 , and most of the hot air is gathered under each cooling fin 3 . When the air driven by the rotation of the fan 6 is blown downward, the airflow formed can flow up, down, left, and right between the crisscross fins 3, so that the hot and cold molecules of the air between the fins 3 can be exchanged quickly, so that The heat accumulated under each cooling fin 3 spreads upward rapidly. In addition, since the corners of the four sides of the heat dissipation fins 3 have radians, the hot air can flow smoothly, and the gaps 31 formed between the heat dissipation fins 3, when the hot air flows rapidly, the heat flows through the gaps 31 to the surroundings. Dissipation can achieve the effect of rapid heat dissipation.

Please refer to the two styles of the third embodiment of the utility model radiator structure 1 shown in Fig. 8 and Fig. 9, wherein the upper end of the fin 9 bent by the plate 91 is provided with a longitudinal The notch 92 can increase the area of the air driven by the fan 6 to blow downward, and make the air have more passages, so as to promote the rapid dissipation of hot air outward.

The utility model has the advantages of:

1. The arrangement of the heat dissipation fins provided by the utility model can provide rapid exchange flow of cold and hot molecules of the air above and below the fins, so that the heat accumulated under each heat dissipation fin can be diffused upward without causing the central processing unit to The resulting high temperature accumulates under the fins, helping the hot air to be carried away quickly.
