摘要: A monogroove heat pipe has a single central manifold communicating with plural parallel connected evaporators and a single condenser. The invention is directed to a tubular screen device which is axially positioned within the liquid channel of the manifold. A number of longitudinally spaced holes are formed in the body of the screen device, each hole being defined by cusp edges which are turned outwardly from the screen body into joint ends of the condenser and evaporator liquid channels. The existence of the screen material at the joint between condenser, evaporators, and the manifold assists the establishment of a primed condition in the heat pipe, even in a zero "g" environment for any initial liquid distribution within the heat pipe.

摘要: A thermal management system using heat pipe principles and incorporating capillary-pumped equipment mounting panels such that a heat transport loop without moving parts is provided. The panels can function to either absorb heat or to reject heat and can interface with heat generating equipment or heat radiators. Each panel comprises a pair of coextensive flat plates bonded together with a thin, fine-pore sheet wick interposed therebetween. A network of liquid grooves in one plate is in fluid communication with the sheet wick which covers the grooves and most of the plate and a separate liquid line connecting the panels. A network of vapor channels in the other plate is in fluid communication with the wick and with a separate vapor line connecting the panels. The vapor channel networks of the panels and the liquid groove networks of the panels are connected such that the panels are arranged in parallel in the fluid circuit or loop. A heat input into panels in the loop causes evaporation of liquid off the surface of the sheet wick. Vapor from the evaporated liquid is circulated to panels serving as cold sinks where the vapor is condensed. Capillary action of the wicks returns the condensate to the panels being heated where the cycle is repeated.

摘要: An improved capillary pumped loop evaporator includes circumferential grooves formed in the outer heat exchanger portion of the evaporator. The grooves open to the interface existing between the heat exchanger and a centrally positioned tubular wick. Axially extending vapor channels are formed in the wick and also open onto the interface. The circumferential grooves continuously communicate with the interface and provide a vapor escape to the vapor channels which direct vapor passage from the evaporator. By shortening the vapor path from the interface, a thinner vapor barrier is possible at the interface which results in more efficient heat transfer.

摘要: A re-entrant groove heat pipe provides capillary channel fin surfaces which are smooth, continuous, and offer a large radius of curvature upon which an extended thin film of working liquid may develop. Superior formation of thin films of the working fluid allows heat to be conducted more readily between the surface of the heat pipe and the surface of the fluid where evaporation and condensation takes place.

摘要: A heat pipe radiator system is rendered more survivable against laser attack while providing higher thermal performance with significantly lower weight. In order to achieve these advantages, the radiator fin is fabricated from carbon-carbon material which is quite resistant to laser destruction as well as exhibiting twice the thermal conductivity of ordinary metals, such as aluminum. An integral clamp secures the fin to each heat pipe, thereby thermally decoupling the fin from the heat pipe when layer heating occurs. A mesh heat pipe wick creates a vapor barrier in the interior of the heat pipes so that continuous operation of the heat pipe is ensured, even when the pipes are subjected to localized laser heating. The heat pipes are wrapped in multi-layer metal foil insulation to greatly reduce direct laser heating of the heat pipes.
