Description

Central processing unit cooling plate

The utility model relates to a heat dissipation plate, in particular to a heat dissipation plate of a central processing machine with an improved structure.

Existing heat sink A of the central processing unit is shown in Figure 3: it is provided with a plurality of heat sinks C parallel to and perpendicular to the metal plate body B on the high thermal conductivity metal plate body B and being the same body, to increase the heat dissipation area and improve heat dissipation. effect, and a cooling fan D is provided on the plurality of cooling fins C to increase the air flow rate. However, in this structural design, since the cooling fins C are arranged parallel to each other, the cooling wind can only be discharged at both ends of the channel E between the cooling fins C, and the direction perpendicular to this is blocked by the cooling fins C and cannot be discharged, so it affects heat radiation. However, the heat generated by the central processing unit is surprisingly large, and the surface temperature often reaches above 80°C, and it must be cooled to maintain it below 50°C. This kind of cooling plate structure has been difficult to achieve.

The purpose of the utility model is to provide a heat dissipation plate of a central processing unit with relatively good heat dissipation effect.

The purpose of this utility model is achieved in this way: the cooling plate of the central processing unit includes a plate body and a fan. The plate around the circular space is provided with a cylindrical cooling column perpendicular to the plate and in the same body as the plate. The gaps between the cylindrical heat dissipation columns form a circuitous air exhaust channel.

The above-mentioned design uses many cylindrical heat dissipation columns on the plate body to enclose the circular space, which is used to increase the heat dissipation area of the heat dissipation plate directly against the wind, thereby achieving the effect of greatly improving the heat dissipation effect of the heat dissipation plate.

Below by accompanying drawing and embodiment the utility model is described further again.

Fig. 2 is a three-dimensional schematic diagram of the utility model after the cooling fan is embedded;

Fig. 3 is the schematic diagram of existing CPU cooling plate;

As shown in Figures 1 and 2: the utility model includes a plate body 2 and a fan 3; the heat dissipation plate 1 is molded from a high thermal conductivity alloy, and its plate body 2 can be in various appropriate shapes. The plate body 2 of this embodiment is The central processing unit is square, and the center of the plate body 2 is provided with a circular space 4 that is integrally embedded with the fan 3 for the cooling fan 3 to be embedded. On the plate body 2 around the circular space 4, there are a plurality of cylindrical heat dissipation columns 5 that are perpendicular to the plate body 2 and are the same body as the plate body 2, and surround the circular space 4 heavily for direct wind exposure. The heat dissipation area of the heat dissipation plate 1 is increased. The gaps between the cylindrical heat dissipation columns 5 form a plurality of roundabout air exhaust channels 6 for the exhaust air of the fan 3 to pass through and be discharged into the air around the heat dissipation plate 1 . At the same time, the exhaust air also takes away the heat of each cylindrical cooling column 5 to reduce its temperature. Therefore, when the cooling fan 3 is in operation, not only the circular space 4 of the heat sink 1 is directly cooled, but also the plurality of cylindrical heat dissipation columns 5 of the heat sink 1 are cooled, so that the temperature of the entire heat sink 1 is lowered.

The heat dissipation plate 1 sample device of the present utility model is installed in the position of the existing heat dissipation plate A to replace the existing heat dissipation plate A for experiments. When the main engine is used for the same time, the average temperature of the surface of the central processing unit is lower than that of the existing heat dissipation plate A. 3.5°C-5.5°C, it proves that it can achieve the expected effect and is of great use value.
