Abstract
An electronic apparatus comprises an electronic circuit unit having heat-generating electronic parts and cooling jackets fed with a coolant so as to cool the heat-generating electronic parts, and a coolant cooling unit having a heat exchanger for cooling the coolant from the cooling jackets and a pump for pressurizing and feeding the cooled coolant to the cooling jackets. The electronic circuit unit and the coolant cooling unit are housed in the same cabinet, and a partition plate is provided between the electronic circuit unit and coolant cooling unit to partition the two so that in the event of occurrence of liquid leakage, the coolant may be prevented from migrating from the coolant cooling unit to the electronic circuit unit. A coolant drainage drain may be provided at the bottom of a U-shaped portion of a path for circulating the coolant to facilitate drainage of the coolant.
