[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat dissipating device used for a component in which a heat generating component and a weak heat component are mixed, such as a display device and a control device of a game machine such as a pachinko machine.

[0002]

2. Description of the Related Art In order to prevent fraud, a display device and a control device mounted on a pachinko machine include a heat-generating component such as a capacitor, a resistor or a coil and a weak heat component such as a semiconductor element or a semiconductor integrated element in a case. Mixed in a sealed internal space.

[0003]

However, in the conventional display device and control device, the case has a heat radiation hole. However, in order to prevent fraud, the heat radiation hole is difficult to take by an unauthorized operation rod commonly called a piano wire. Since the caliber is set to, for example, 2 mm or less, it is difficult for the heat generated from the heat-generating components that are continuously turned on to radiate to the outside of the case while the pachinko parlor is being opened, and it is undeniable that the weak-heat components are thermally degraded.

Accordingly, the present invention provides a heat radiator capable of improving the cooling of a component containing a heat-generating component and a weakly-heated component.

[0005]

According to the present invention, there is provided a case for storing a heat-generating component and a weakly heat-generating component, and a heat radiating portion provided on an outer surface of the case.
Therefore, according to the present invention, since the heat inside the case is released from the case to the outside via the radiator, the weak heat component inside the case can be appropriately protected from the heat generated by the heat generating component. or,
In the present invention, if the heat radiating portion is formed by a heat radiating cover that is put on the case, the shape of the case and the heat radiating portion can be made to be shapes suitable for their respective functions, and the heat radiating area of the heat radiating portion is increased, The heat radiation performance can be improved.
Further, in the present invention, the heat dissipation cover includes a back surface and a side surface extending forward from a periphery of the back surface, the back surface contacts the back surface of the case, and the side surface forms a gap between the case and the case. If it is formed, the surface area of the heat radiation cover becomes larger than the surface area of the case, and the heat radiation performance is improved. In the present invention, if the side surface forming the gap between the case and the case is provided with a notch, heat is released to the outside from the gap by the air flowing through the gap, and the heat radiation performance is improved. Further, in the present invention, if the heat dissipating cover includes a back surface portion and a side portion extending forward from the periphery of the back surface portion and an extending portion extending outside the side surface portion, the heat dissipating area of the heat dissipating cover increases, Heat dissipation performance is improved. Further, in the present invention, when the heat radiating cover is connected to the metal component of the gaming machine, heat is transmitted from the heat radiating cover to the metal component, and the heat is also radiated from the metal component, so that the heat radiating performance is further improved.
