Patent ID: 7558064

Claim:
A cooling apparatus for cooling a semiconductor device to a target temperature at which said semiconductor is burnt in at atmospheric pressure; said semiconductor device including a first surface, said first surface being planar, said semiconductor device passing electric current therethrough and generating heat so that a temperature thereof rises above said target temperature and a temperature of said first surface rises; said apparatus comprising: compressed air supply means configured to supply compressed air at an initial stage when the electric current starts passing through the semiconductor device and thereafter; liquid supply means for supplying liquid, said liquid being water, that cools said semiconductor device, said liquid having a saturation temperature at said atmospheric pressure that is lower than said temperature of said first surface when said temperature of said first surface rises, said liquid supply means being configured to be started after said temperature of said first surface exceeds said saturation temperature; and a sprayer configured to receive said compressed air and said liquid and to mix said compressed air and said liquid so that said liquid atomizes and expands radially and reaches said first surface.
