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: An in-line, non-condensible gas trap for a liquid line which includes an interior mesh tube through which fluid can flow to a trap outlet. Non-condensible gas is trapped outwardly of the mesh tube due to capillary action and periodically the collected gas is vented thereby ridding the liquid line of the non-condensible gas. The present trap operates well in outer space environments (zero gravity) as well as normal ambient conditions (1 g).

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 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: A controlled low temperature chamber for a microscope has a vacuum chamber in a housing. The housing has a top panel and a bottom panel. A mounting in the chamber mounts a sample in a manner whereby the sample is microscopically observable. The mounting includes a base member, a pair of spaced supports extending perpendicularly from the base member and a pair of spaced platforms supported by the supports. Each of the platforms has an upper surface on which the sample rests and a spaced undersurface beneath the sample. A temperature control system maintains a specified temperature in the chamber, applies a controlled temperature gradient on the sample and moves the gradient along the sample in a controlled manner, thereby directionally solidifying and melting the sample, as desired.

摘要: The coolant fluid evaporated in a compact heat absorbing panel (12) utilizing monogroove heat pipes in a pumped two-phase system is replenished through a liquid inlet control valve (35) under the control of an ultrasonic liquid presence detector (40) which is connected to the panel (10). The detector (40) maintains the desired liquid quantity in the panel's liquid coolant channels (25), thereby dynamically responding to varying heat loads.
