Abstract
In a computer system using an expanded unit for obtaining an expanded function, a heat sink of a computer main body and a heat sink of the expanded unit are connected to each other when the computer main body and the expanded unit are connected to each other. A surface area of the heat sink can be increased, and the radiation effect can be improved. Thereby, the computer main body can be operated under a full power mode in which sufficient radiation effect is assumed. Particularly, the performance of a small-sized computer whose setting space of the heat sink is limited can be improved.
Claims20
A computer system comprising:
- a computer main body;
- an expanded unit detachable from the computer main body, the expanded unit adding a predetermined function to the computer main body when the expanded unit is attached to the computer main body;
- a first heat sink provided in the computer main body;
- and
- a second heat sink provided in the expanded unit, the second heat sink and the first heat sink being connected to each other, and functioning in cooperation with each other, when the expanded unit is attached to the computer main body.

A computer system comprising:
- an expanded unit, having a structure to be detachable from a computer main body, connected to the computer main body to realize a predetermined expanded function;
- a first radiator means, provided in the computer main body, for radiating an interior of the computer main body;
- a second radiator means, provided in the expanded unit, for radiating the interior of the computer main body, said second radiator means contacting said first radiator means when the expanded unit is connected to the computer main body;
- means for detecting that the expanded unit is connected to the computer main body;
- and
- means for setting an operation mode of the computer main body to a normal power mode when the computer main body is singly operated without the expanded unit, and to a high power mode when the detecting means detects an existing connection between the computer main body and the expanded unit, the high power mode being higher in power than the normal power mode.
