[Problems to be solved by conventional techniques and devices]

 In recent years, notebook computers have become increasingly widespread in the computer market. It is generally believed that the user's image of a notebook computer is small and convenient, but placing all personal computers in a notebook-sized space requires fairly precise manufacturing techniques. Due to the small volume of a notebook computer, it is impossible to place all components of a typical desk computer on a notebook computer. For example, the power supply of a desk-type computer (desktop-type personal computer) has a large fan that plays the role of heat dissipation inside the main mechanism, but the space available for a notebook-type computer is limited. Therefore, a configuration like the desk-type computer cannot be provided inside. In addition, notebook computers have a unique design. When a battery is used as a power source for a short period of time, the battery power is low, so that overheating does not occur, but if a rectified and stepped down local power source ( When using "public power supply" or "public power supply") as the power supply, the local power supply is high power, so if it is used for a long time, its heat cannot be naturally dispersed due to heat dissipation . In order to solve this problem, a notebook type heat radiator for notebook computers is already on the market.

On the other hand, according to a “heat dissipating device for a notebook computer” disclosed in Taiwan Utility Model No. 322969, air convection between the inside and the outside of the notebook computer can be achieved by attaching the heat dissipating device. Generates action and performs forced heat dissipation. However, such an air convection effect hardly occurs in practice, and in particular, the conventional utility model can simply send airflow from outside to the inside of the notebook computer, Since it is quite difficult to flow hot air inside the notebook computer to the outside, such air convection action has not been actually proved. This is because the case structure of the notebook type computer is formed in a closed type, so that the air convection can be generated only in the gap between the keyboards. However, the keyboard of a notebook computer is generally of a film type, and since the film is mounted on a plate, no air convection occurs.

As described above, since the case structure of the notebook computer is formed as a closed type, air can be blown into the notebook computer, but the effect of air convection can be obtained. Absent. Therefore, the heat dissipation problem associated with the utility model notebook computer has not been solved yet, and other solutions should be further devised.

The present invention solves the above-mentioned problems, and provides a forced heat dissipating device in which a heat dissipating air flow sufficiently circulates in and out of a notebook computer to obtain a favorable heat dissipating effect.

A notebook-type computer, wherein a fan unit of an unspecified type is provided so as to be able to operate, and the air blowing channel and the air extracting channel respectively correspond to an inlet and an air outlet provided in a whirl inside the battery compartment. The present invention provides a convection-type forced heat dissipating device.
