Heat dissipating base for laptops

A heat dissipating base for laptops includes a casing member, inside which at least a fan is located, and an air duct which allows the fan to expel the air to the outside of the casing member. A cover member with an inclined top plate is joined to the casing member and an opening is made on the cover member to allow the fan to draw air into the casing member. The top face plate is curved inward and forms a gap between the top face plate and the bottom of the laptop resting on the heat dissipating base. The top face plate has multiple ventilation holes, so the cool air is sucked through the holes to efficiently cool down the temperature of the laptop.
Laptops have been continuously upgraded for more function and higher computing speed. In the mean time, the heat produced by the laptops is also dramatically increased. The high temperature has to be reduced; otherwise components of the laptop such as CPU, memory, adaptor cards, etc. would be over heated and failed. The operational lifespan of the laptop would also be affected if the laptop is continuously operated under such high temperature. As a result, the auxiliary devices for heat dissipation such as the heat dissipating bases are therefore greatly demanded by laptop users.
Accordingly, a heat dissipating base for laptop is provided herein. The heat dissipating base comprises a hollow casing member, a cover member mounted on the base, and a top face plate in turn mounted on the cover member. The casing member has at least a fan housing within which a fan is installed, and an air duct allowing the fan to expel hot air to outside of the casing member. The cover member has at least an opening which is located correspondingly to the fan housing and allows the fan to draw air into the casing member. The top face plate has multiple ventilation holes which are located above the opening of the cover member. The cover member and the top face plate are configured such that the top face plate is curved inward, leaving a gap between the bottom of the resting laptop and the top face plate itself. The heat produced by the laptop, and cool air are together sucked into casing member through the gap, the ventilation holes of the top face plate, and the opening of the cover member, and then they are expelled through the air duct on the lateral sides of the casing member, causing a well air circulation system and an enhanced heat dissipating efficiency.
