Abstract

Sweating-boosted air cooled heat-pipe condensers employing a nanowick micro fin structure to form a sweating boosted heat dissipation system, wherein the nanowicks may be layered.

First claim

What is claimed is:

1. A sweating boosted heat dissipation system comprising:
at least one heat pipe comprising:
at least one evaporator section formed from at least one inner grooved tube;
at least one condenser section comprising at least one cooling tube with at least one hybrid wicking fin;

at least one steam supply pipe providing steam to the at least one condenser section;
at least one cold water source for dripping water onto the at least one hybrid wicking fin;
wherein the at least one hybrid wicking fin comprises a partially hydrophilic nanowick coating comprising an inner layer formed by a carbon nanotube and an outer layer formed on the inner layer comprising TiO 2 to form an active interface on the partially hydrophilic nanowick configured to decompose organic matter; and
wherein the inner layer further comprises a polyurethane organic corrosion protection coating and the outer layer further comprises polyurethane and is configured as a porous layer to promote wicking along the at least one hybrid wicking fin.

2. The sweating boosted heat dissipation system of claim 1 , wherein the nanowick coating is self-cleaning.

3. The sweating boosted heat dissipation system of claim 1 , wherein the nanowick coating exhibits photo induced superhydrophilic transition.

4. The sweating boosted heat dissipation system of claim 1 , wherein the at least one cooling tube is formed from copper.

5. The sweating boosted heat dissipation system of claim 4 , wherein a layer of nickel is deposited on an external surface of the at least one cooling tube.
