に対して十分でないということが問題となっている。2. Description of the Related Art Recent electronic devices often require two contradictory performances such as high performance and miniaturization (portability), as seen in examples of notebook personal computers and mobile phones. Regarding higher performance, higher integration of semiconductor LSI,
As the frequency increases, the heat generation density of the LSI increases, and as a result, the temperature of the LSI increases and the operation becomes unstable. As for miniaturization, there is an increasing demand for longer life of battery (secondary battery) performance in portable electronic devices. However, at present, there is a problem that the battery operating time of a notebook computer, a video camera, and the like is not sufficient for the intended use.

Regarding the temperature rise of the SI, the temperature rise of the LSI has been suppressed by a cooling structure using a radiation fin, a heat pipe, or the like, or a forced air cooling using a small fan. Regarding the problem of the life of a battery (secondary battery), a method of mounting a second battery to extend the life has been adopted.

う面に於いて十分とは言えなかった。However, in these methods, for example, the adoption of the radiating fins and the heat pipe increases the weight of the entire electronic device, and also increases the total weight of the mounting of the second battery. This is contrary to the purpose of the original portable electronic device. Cooling an LSI by mounting a small fan results in shortening the life of the secondary battery due to the consumption of the driving power of the fan, which can be said to be sufficient in terms of miniaturization and weight reduction. Did not.

寿命を延ばすという点では一応の効果を奏している。Therefore, for example, Japanese Patent Application Laid-Open No. 9-92761 discloses a method of converting heat energy generated in a semiconductor chip into electric energy by a thermoelectric converter, thereby driving a small fan and cooling a semiconductor package. It has been disclosed. FIG. 3 shows a cross-sectional view of a conventional electronic device. Referring to the drawings, reference numeral 1 denotes a semiconductor package, 7 denotes a thermoelectric converter, and 16 denotes a small fan. This conventional technology converts the thermal energy generated by the heat generated by a semiconductor chip to supply power to a small fan. Therefore, if this technology is applied to an electronic device equipped with a secondary battery, it will not be possible to drive the fan even if the fan is driven. Because the next battery does not run out,
In terms of prolonging the life, there is a certain effect.

There is a problem that the volume and weight of the entire electronic device increase by the volume of the small fan. In this regard, considering the application to notebook PCs, mobile phones, video cameras, etc., one of the most important features of these products, small and lightweight, is because the size of the device is large.
