Abstract
A sandwiched honeycomb panel with built in heat pipes includes a radiating fin which is integral with an envelope having a heat pipe formed therein. A heat block may be used in place of the radiating fin.
Claims5
A honeycomb sandwich panel comprising:
- a) a honeycomb core sandwiched between outer surfaces;
- b) a heat pipe formed in an envelope embedded in the honeycomb core;
- and
- c) a heat transmitting plate which is directly bonded, on its lower surface, to the envelope having the heat pipe therein and which is partially exposed at its upper surface, and is made from a material assuring good heat conducting performance and wherein the exposed portion of the heat transmitting plate is flush with the one of the outer surfaces.

2 more elements
A honeycomb sandwich panel for dispersing heat from a device, the panel comprising:
- a honeycomb core;
- an envelope embedded in a first portion of the honeycomb core such that the envelope has two opposite sides which are parallel to opposing surfaces of and not covered by the honeycomb core, wherein the envelope includes a heat transmitting plate on one of the two opposite sides;
- outer surfaces covering the opposing surfaces of the honeycomb core and the opposite sides of the envelope and heat transmitting plate except for an exposed portion of the heat transmitting plate, the device being attached to the panel so as to contact the exposed portion of the heat transmitting plate, and wherein the exposed portion of the heat transmitting plate is flush with the outer surface;
- at least one heat pipe formed in the envelope and extending into a second portion of the honeycomb core.
