BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a cooling device suitable for cooling an electronic part such as a microprocessor unit, which generates heat.
2. Description of the Related Art
JP-A-8-83873 discloses a cooling device for cooling a microprocessor unit. The cooling device has a radiation plate integrally formed with a radiation fin. The radiation fin is formed by partially cutting and bending the radiation plate. However, it is difficult for the radiation fin, which is integrally formed with the radiation plate, to provide a sufficient radiation area.
SUMMARY OF THE INVENTION
The present invention has been made in view of the above problem. An object of the present invention is to increase a radiation area by adopting a corrugated fin to reduce size and weight as a whole. Another object of the present invention is to securely protect a corrugated fin not to be crushed by external force.
According to the present invention, briefly, a cooling device for radiating heat from a heat radiating member has a radiation plate, a corrugated fin disposed on the radiation plate, a blower, and a blower case covering the blower, and first and second support members connected to the radiation plate. The first and second support members face the corrugated fin at both sides in a corrugated direction of the corrugated fin. The corrugated fin increases a radiation area largely, resulting in effective heat radiation from the heat generating member. The first and second support members protect the corrugated fin from an external force.
The first and second support member can be fixed to the radiation plate by an elastic force thereof. Accordingly, the fixation is readily achieved with a simple structure. The first and second support members may be integrally formed with either one of the blower case and the radiation plate. Otherwise, the first and second support members may be separate from both the blower case and the radiation plate. A support casing connected to the blower case and the radiation fin can have the first and second support members.
