Cooling means for a heated surface comprising an enclosure for enclosing the heated surface and two oppositely charged interleaved radial arrays of microelectrodes positioned on the surface within the enclosure. The first plate-shaped member has a first surface thermally connectable with a heat generating element and a second surface. The heat exchange pipes are filled with an uncrosslinked high density polyethylene phase change material. A primer layer may be sandwiched between the bonding layer and the decorative layer.
