れてきた。In general, electrical equipment, especially semiconductor elements such as diodes, silices, and transistors, are not only susceptible to changes in their characteristics due to changes in temperature, but also have the risk of being damaged by local heat generation if the environment for heat dissipation is poor. For these reasons, various types of cooling devices have been considered.

Reference numeral 5 denotes a metal hose nipple attached to the water cooling block 3 by screwing or brazing. The hose nipple 5 is connected to the water cooling block by a piping hose 6, and water flows through the piping hose 6 and the water channel 4 in the direction of the arrow shown. Also, 7 is water cooling block 3

Further, the semiconductor element 1 is electrically insulated from an external press-contacting structure (not shown) by the insulating seat 7.

ことが考えられるが、これらは容易でない。The conventional semiconductor device cooling device is configured as described above, and the voltage applied to both ends of the semiconductor device is directly applied to the water inside the piping hose 6, the hose nozzle 5, and the water cooling block 3, so that the resistance of the water is reduced. If the value is low, a large amount of leakage current will flow through the water path, especially if DC current is applied.
The nozzle 5 is melted and worn out due to current corrosion, and the water cooling block 3 becomes unusable in a short period of time. Furthermore, if a person uses the water discharged from this cooling device in a remote location, there is a risk of electric shock, which is dangerous. In order to prevent these problems, it is possible to increase the water resistance value or to control the water quality, but these are not easy to do.

Also, current corrosion does not occur.
