<p>PURPOSE:To achieve a reduced an installation space, ensured installability equivalent to that of a conventional air-cooled electronic device, a reduced time which installation work requires, a small-sized pump and an improved reliability when a refrigerant leaks or when a pipe is eroded in a liquid-cooled type electronic device. CONSTITUTION:An electronic circuit casing 1 is constituted in such a way that it has an L-shaped cross section. A cooling casing 2 for cooling a liquid refrigerant is connected and fitted to this L-shaped electronic circuit casing 1 by means of couplings 62, whereby the entire casings are assembled into a rectangular-parallelopiped single unit. The cooling casing 2 for the liquid- refrigerant houses a heat exchanger 28, a fan 38, a pump 32, a device 32 for maintaining the purity of the refrigerant, and devices for cooling heat-generating electronic components 20. The cooling casing cools the heat-generating components 20 that are mounted on a substrate 22 with a partition plate 61 sandwiched between the cooling casing and the substrate.</p> |
