The present invention relates to a heat dissipation device, for example, to a heat dissipation device having heat dissipation fins in different directions.

Recently, various electronic devices have been provided to users, and among the parts provided inside of the electronic device because functions are integrated in the electronic devices, parts that generate high temperature heat (hereinafter referred to as 'heating modules') will be provided. You can.

If the high-temperature heat generated from the heat generating module is not smoothly discharged, not only the heat generating module but also the surrounding parts may be affected, resulting in malfunction of the parts and damage, etc., and the electronic device may not function properly. Of course, in severe cases, the electronic product cannot be used due to damage to parts.

Accordingly, various types of heat generating devices are provided in the electronic device so as to dissipate heat generated from various heat generating modules.

As described above, as a heat generating module that generates high temperature heat among various components mounted on an electronic device is mounted, a need for an efficient heat dissipation device is increasing.

Specifically, the heat dissipation area portions 131, 132, 133, and 134 are heat dissipation areas where heat dissipation fins 121, 122, 123, and 124 projecting in parallel in the same direction are formed on the plate 110. At least one or more may be formed on the plate 110. The heat dissipation area portions 131, 132, 133, and 134 will be described as having, for example, a symmetric shape on the plate 110. However, the heat dissipation area parts 131, 132, 133, and 134 may be formed asymmetrically depending on the position of the inset part 140 described later or the position of the heating module 170. In addition, the heat dissipation area portions 131, 132, 133, and 134 may be formed adjacent to each other along a direction on the plate, or may be formed in a direction perpendicular to the gravitational direction and the gravitational direction.

Specifically, the heat dissipation area portions 131, 132, 133, and 134 may be positioned adjacent to each other and adjacent to each other with the inset portion 140 as the center. In the inset unit 140, air introduced through the radiating fins 121, 122, 123, and 124 of different angles may be changed into turbulent flow in the inset unit 140, and accordingly, as energy is generated, air flow occurs. Can be. Accordingly, the flow of air can be made more active, and accordingly, the movement of air between the heat dissipation fins 121, 122, 123, and 124 can be efficiently generated, thereby increasing heat dissipation efficiency.

As mentioned above, the heat dissipation region parts 131, 132, 133, and 134 adjacent to each other according to one of various embodiments of the present invention may be divided symmetrically or non-symmetrically based on the inset part 140.
