ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a radiating device for electronic appliances, and more particularly to a radiating device which is capable of protecting components of an electronic appliance which have a low degree of heat tolerance from heat by promptly emitting the heat generated by a transistor (hereinafter, called TR) or an integrated circuit (IC) of the electronic appliance.
2. Description of the Conventional Art
Usually, the TR (or IC) is employed as a main component of an electronic appliance. When operating, such TR (or IC) generates a high temperature which results in damaging other peripheral components of the electronic appliance which are not strong enough to endure the high temperature, and eventually leads to the improper operation or breakdown of the electronic appliance.
In order to prevent the other peripheral components from being damaged by the heat generated by the TR (or IC), a conventional electronic appliance has employed a radiating device which compulsorily emits the heat generated by the TR (or IC).
Such radiating device, however, has two types; one is a board type and the other is an extrusion type. In the board type
1
, as can be seen in
FIG. 1A
, a body
1
a
is made of aluminuous materials to facilitate the heat radiation and a fastening hole
1
b
is provided in a center portion thereof, to which the TR (or IC) is fastened by a fixing member N such a screw, and thus the heat radiation is achieved through a surface of the body
1
a.
Further,
FIG. 1B
shows the extrusion-type radiating device
1
′, wherein predetermined portions of the body
1
a
of the board type
1
are formed extruded to enlarge a radiation surface area thereof and thereby more effectively carry out the heat radiation.
However, in the board-type radiating device
1
, when increasing the area or height of the device to improve a radiation effect, the manufacturing cost is accordingly increased. Also, due to the limitation of the area or height of other components provided in a chassis, since it is impossible to unlimitedly enlarge the size of the radiating device, the heat is radiated under a certain limit.
While, the radiation effect is improved in the extrusion-type radiating device
1
′, since the surface area thereof has been enlarged. However, the size of a product is undesirably increased by which the area occupied by the device
1
′ in the chassis is enlarged.
Also, the conventional board-type and extrusion-type radiating devices
1
,
1
′ have another disadvantage of being not capable of safely protecting the other peripheral components in the electronic appliance from the heat, since the radiation is gradually performed by these devices.
SUMMARY OF THE INVENTION
Accordingly, the present invention is directed to a radiating device for an electronic appliance which obviates the problems and disadvantages due to the conventional art.
An object of the present invention is to provide a radiating device for an electronic appliance that is configured to be comparatively smaller than the conventional radiating device but of which radiation area to the unit area is maximized, thereby optimizing the radiation effect and rapidly carrying out radiation.
To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described, in a radiating device for an electronic appliance which radiates the heat generated by components of the electronic appliance, the improvement has a plurality of embossed portions and vents at surfaces thereof, wherein the vents are provided to facilitate the rapid radiation.
