Abstract

A heat dissipating device. The heat dissipating device comprises a receptor plate to be placed over a device that generates heat, an evaporator coupling to the receptor plate, a condenser column placed in fluid communication with the evaporator, and a set of condenser extension surfaces extending from the condenser. The evaporator includes a modulated porous layer and stores liquid. The condenser column includes a non-wetting surface. The condenser extension surface facilitates heat dissipation.

Claims (14)

1. A computer system comprising:

a main logic board;

an integrated circuit device interconnected to the main logic board;

a receptor plate placed over the integrated circuit chip device and coupled to the main logic board;

an evaporator coupling to the receptor plate, the evaporator coated with a modulated porous layer and storing a liquid; and

a condenser column placed in liquid communication with the evaporator, the condenser column having a non-wetting surface.

2. The computer system of claim 1 further comprising:

a set of condenser extension surfaces extending from the condenser column, the condenser extension surfaces to facilitate heat dissipation.

3. The computer system of claim 2 wherein the condenser extension surfaces include any one of fins, channels, and plates.

4. The computer system of claim 1 wherein the integrated circuit device is any one of a semiconductor device, a transistor, a capacitor, a resistor, a sensor, an optical element, a microprocessor, a memory structure, a power source, a graphic controller chip, a display driver, and a display element.

5. The computer system of claim 1 wherein the receptor is placed over the integrated circuit device so as to seal the integrated circuit device.

6. The computer system of claim 1 further comprises a thermo interface layer disposed between the receptor plate and the integrated circuit device.

7. The computer system of claim 1 wherein the condenser column is coated with a hydrophobic material to create the non-wetting surface.

8. The computer system of claim 1 wherein the condenser column recycles the liquid down to the evaporator.
