Since the conventional cooling system of this type is configured as described above, the internal air (7) inside the sealed box (1) is heated by the heat generated by the electronic components or electrical equipment contained therein, and its temperature rises. . Then, this internal air whose temperature has increased (7
) is powered by the heat pipe (
When the heat medium in the heat pipe (2) is heated by the heat medium in the heat pipe (2), the heat medium absorbs heat from the blown internal air (7) in the form of latent heat of vaporization. It evaporates and rises to the heat dissipation part (2b) of the tote vibe (2). The evaporated heat medium is cooled by the external air (8) blown onto the heat radiation part (2b) by the external electric fan (6), and is condensed and liquefied to the heating part (2a) of the heat vibrator (2). However, by repeating the above-mentioned operation, the inside of the sealed box (1) is heated again by the high-temperature internal air (7) blown onto this heat radiation part (2a) by the internal electric fan (5). It is designed to cool down to turbidity.
