Abstract: PURPOSE: A resonance cooling apparatus for an electronic appliance is provided to improve the heat emitting effect of a radiator or a convector without using a plurality of fans. CONSTITUTION: A resonance cooling apparatus for an electronic appliance emits the heat generated from a heating device of the electronic appliance surrounded by a case. The resonance cooling apparatus comprises a driving device(20) for generating a driving signal having a frequency identical to the resonance frequency of a fluid filled in the case. A sound wave vibrator(16) is provided to guide the sound wave to the case in response to the driving signal of the driving device(20). The driving device(20) includes a signal oscillator for oscillating the driving signal identical to the resonance frequency of the fluid and an amplifier for amplifying the driving signal.

Abstract: PURPOSE: An anisotropic porous fin is provided to reduce the loss of pressure remarkably while maintaining the heat transmitting performance of an isotropic porous fin. CONSTITUTION: An anisotropic porous fin has multiple long holes(21,23) formed on a porous member(25) having many porosities formed uniformly while passing through the inner part of the porous member in parallel at a certain interval. Herein, the porous member is formed of aluminum or copper, and has 88% of porous degree and formed of foam metal over 100W/mK of heat conductivity. And the long holes formed on the porous member is formed by drilling work or laser processing work.

Abstract: PURPOSE: A foamed metal radiator is provided to obtain a lightweight radiator small in size, while improving radiation performance and simplifying the structure of the radiator. CONSTITUTION: A radiator comprises a metal plate(20) arranged at the outer surface of the heat generating source; and a foamed metal(10) having air pores and which is welded to the metal plate through a brazing process. An aluminum, aluminum alloy or copper is used as the metal plate and foamed metal. The radiator further includes a fan for causing flow of ambient air. The foamed metal is manufactured by blowing air bubble into the molten metal and solidifying the molten metal. Alternatively, the foamed metal is manufactured by stacking synthetic resins with particles of predetermined size, injecting molten metal into stacked resins, solidifying the molten metal and removing the synthetic resin. Thus-manufactured foamed metal has a superior mechanical strength.
