    摘要: A variable conductance heat pipe includes an electronic component mounting plate serving as the evaporator of the heat pipe. The evaporator is connected to an air cooled condenser which condenses vapor flowing from the evaporator. The evaporator has a sump located at the lowest gravity point of the evaporator passage. By either vaporizing or pumping liquid from the sump and passing it back through the heat pipe a continuing wetted condition exists in the heat pipe which can accommodate heat dissipation transients by the electronic components. A control loop is closed through the heat pipe for controlling the penetration of an inert gas into the heat pipe condenser to maintain a constant temperature for the electronic components mounted thereto.

    摘要: A serpentine continuous vapor passage is formed in a metal card which mounts electronic components. Elongated channels of the passage evaporate the contained liquid in response to conducted heat from mounted electronic components. By mounting the side edges of the card to heat conductive retaining means, the evaporated fluid becomes condensed at end sections of the passage thereby transferring the heat from the card and converting the evaporated liquid in a gaseous state back to a liquid state. The resultant card is gravity-insensitive and a thermal-resistance path is minimized so that the cooling capability of the card becomes maximized.

    摘要: A thermal pipe switch includes a single vapor channel communicating with two parallel formed liquid channels. Each of the liquid channels is connected to a respective liquid channel in a dual heat sink assembly which thermally contacts a cryocooler. If a first cryocooler becomes operative, liquid in the heat pipe thermal switch will fill a liquid channel communicating with the heat sink liquid channel which thermally contacts an operative cryocooler. The other heat pipe thermal switch liquid channel is filled with vapor so as to thermally decouple its respectively connected thermal cooler from the system.

    摘要: A heat pipe including evaporator and condenser sections is located within a stack for reclaiming vaporized metals. The heat pipe is a variable conductance design which employs a communicating reservoir of non-condensable gas for creating a variably positioned interface with the working fluid within the condenser of the heat pipe. The interface varies as a function of the heat load on the condenser and effectively provides a variable control for maintaining efficient, fairly constant heat transfer across the wall of the condenser. Fixed turbulators are mounted to a lower section of the heat pipe for mixing the vaporized metals flowing through the stack thereby increasing the efficiency of heat transfer between the vaporized metals and the heat pipe. The result is a compact and environmentally rugged heat pipe design.

    摘要: An enclosure covers equipment to be camouflaged from thermal or multi-spectral (thermal, radar visual) detection in spaced relation with the equipment. The enclosure is preferably semi-transparent plastic material sufficiently spaced from the equipment to permit natural convection, or forced airflow over the equipment. In one embodiment, the plastic material has a number of sides with a plurality of openings formed therein for entraining air and a top joining the sides. A chimney is formed in the top and an adjustable discharge damper is provided in the chimney for controlling the flow of air over the equipment. The airflow may be natural or controlled actively or semi-actively.

    摘要: A method for thermally pumping volatile liquids and a pump for use therewith. The pump has an inlet liquid cooled pump chamber having therein a porous inlet membrane and a porous exit membrane defining between them a pump volume. The membranes are permeable to the liquid phase of the fluid being pumped but, when saturated with liquid, are not permeable to the vapor phase of the fluid. A passive check valve system permitting the passage of liquid but preventing the passage of vapor therethrough is thus formed by the membranes. A baffle plate with a heater located in a concavity therein is positioned in the pump volume adjacent the inlet membrane. The pump output is connected to the inlet of a suitable heat transfer system preferably of the heat-pipe type. With the pump filled with liquid, pumping is initiated by turning on the heater, forming a vapor bubble in the liquid in the pump volume. A heat input is continued until the vapor bubble has grown to a size sufficient to expel most of the liquid in the pump volume. The heating pulse is then terminated. Condensation of the vapor bubble then occurs and the resulting drop in pressure causes liquid to be drawn into the pump volume, setting the stage for the entire cycle to repeat.

    摘要: A heat pipe comprising an elongated sealed metallic envelope having at least a pair of longitudinal channels extending along the length thereof. One of the channels is for the circulation of the vapor phase of the working medium in operation and the other for the liquid phase and capillary means are provided to furnish fluid communication therebetween. Dedicated vapor and liquid channels result in low viscous pressure drops, the capillary communication means and circumferential grooving in the vapor channel provide high capillary pressure differences, and circumferential grooving is provided to furnish the high evaporation and condensation film coefficients required. To support higher heat fluxes, wicking can be used to augment the capillary flow from the liquid channel. To support higher evaporator heat flux without the need for wicking means, the heat pipe can be provided with more than one liquid channel, each communicating with the vapor channel by capillary means. The heat pipe can be provided with an integral fin or equivalent means for rejection of heat by radiation to ambient or for attachment to a source of heat in the evaporator region thereof.
