Abstract
A heat spreader includes thin films opposite to each other; cooling liquid filling an internal space between the thin films; and a vibration generating means for vibrating the liquid. Accordingly, the heat spreader has excellent heat spread performance compared to a conventional heat spreader, so can have an ultra slim type structure. Also, the heat spreader has excellent heat spread performance regardless of a direction of gravity, and a space between the thin films is sealed in a state of an atmospheric pressure, to maintain the improved heat spread performance for a long time.
Claims18
A heat spreader comprising:
- at least two thin films disposed opposite to each other and defining a sealed internal space between the thin films;
- a cooling liquid filling the internal space between the thin films;
- a vibrator assembly adapted to vibrate the liquid;
- and
- a concave-convex form formed inside at least one of the thin films adapted to generate turbulent flows of the cooling liquid;
- wherein the vibrator assembly comprises
- a vibrator installed inside the thin films, the vibrator being adapted to vibrate the liquid;
- and
- a signal generator, the signal generator being adapted to generate a frequency signal that vibrates the vibrator.
A heat sink comprising:
- at least two thin films disposed opposite to each other, the thin films each having an outer surface, and defining a sealed internal space between the thin films;
- a cooling liquid filling the internal space between the thin films;
- at least one cooling fin installed at the outer surface of at least one of the two thin films;
- a vibrator assembly adapted to vibrate the cooling liquid;
- and
- a concave-convex form formed inside at least one of the thin films adapted to generate turbulent flows of the cooling liquid;
- wherein the vibrator assembly comprises
- a vibrator installed inside the thin films, the vibrator being adapted to vibrate the liquid;
- and
- a signal generator, the signal generator being adapted to generate a frequency signal that vibrates the vibrator.
A heat exchanger comprising:
- at least two thin films opposite to each other, each said thin film having an outer surface, the thin films defining a sealed internal space between the thin films;
- a cooling liquid filling the internal space between the thin films;
- heat exchanging fins installed at the outer surfaces of the thin films;
- a vibrator assembly adapted to vibrate the cooling liquid;
- and
- a concave-convex form formed inside at least one of the thin films adapted to generate turbulent flows of the cooling liquid;
- wherein the vibrator assembly comprises
- a vibrator installed inside the thin films, the vibrator being adapted to vibrate the liquid;
- and
- a signal generator, the signal generator being adapted to generate a frequency signal that vibrates the vibrator.
A PDP chassis base comprising:
- at least two thin films opposite to each other and defining an internal space between the thin films;
- cooling liquid filling the internal space between the thin films;
- a vibrator assembly adapted to vibrate the cooling liquid;
- and
- a concave-convex form formed inside at least one of the thin films adapted to generate turbulent flows of the cooling liquid;
- wherein the vibrator assembly comprises
- a vibrator installed inside the thin films, the vibrator being adapted to vibrate the liquid;
- and
- a signal generator, the signal generator being adapted to generate a frequency signal that vibrates the vibrator.
