A heat transfer system includes a heat source, a first heat exchanger coupled to the heat source to remove heat from the heat source, and a second heat exchanger coupled to the first heat exchanger to remove heat from the first heat exchanger. The heat transfer system also includes a thermal doubler coupled to the second heat exchanger to remove heat from the second heat exchanger, a first heat pipe coupled to the thermal doubler to remove heat from the thermal doubler, and a second heat pipe coupled to the first heat pipe to remove heat from the first heat pipe.

Vehicle thermal management system

A thermal management system includes a heat transport component and a water-based azeotropic mixture disposed within the heat transport component to move heat from one portion of the heat transport component to another. The mixture includes at least 50% water.

Azeotropic working fluids and thermal management systems utilizing the same

A heat pipe system for conducting thermal energy. The heat pipe system includes a sealed tube having along its length a reservoir region, an evaporator region, and a condenser region, the tube having a first end and a second end and an inside wall. The system also includes a wick disposed adjacent the inside wall of the tube, the wick including a first portion at the first end of the tube and a second portion adjacent the first portion, wherein the first portion of the wick is thicker than the second portion of the wick, and wherein the second portion of the wick does not extend to the second end of the tube. The system also includes a working fluid contained within the tube.

Heat pipe having a wick with a hybrid profile

A method is provided for heat transfer from a surface to a fluid. The method includes directing a first fluid flow towards the surface in a first direction and directing a second fluid flow towards the surface in a second direction. The first and second fluid flows cooperate to cool the surface.

Heat transfer apparatus and method

A system for cooling a canister has first, second and third heat pipes. The first heat pipe has an evaporator and a condenser. The first heat pipe is mounted with its evaporator inside the canister and its condenser outside the canister. The second heat pipe has an evaporator conductively coupled to the condenser of the first heat pipe. The second heat pipe has a condenser. The third heat pipe has an evaporator conductively coupled to the condenser of the second heat pipe. The third heat pipe has a condenser with a plurality of fins on the condenser of the third heat pipe.

Heat pipe system for cooling flywheel energy storage systems

A cooling system is provided for cooling a canister. A first heat pipe is mounted around the perimeter of the canister. The first heat pipe has a condenser. A second heat pipe has an evaporator conductively coupled to the condenser of the first heat pipe. The second heat pipe has a condenser. A heat sink is conductively coupled to the condenser of the second heat pipe.

The invention is a very flexible heat pipe which is constructed of multiple layers of material laminated into the final structure. The center of the symmetrical structure is a coarse screen which creates a vapor space. The layers on either side of the screen are copper felt pads, and the outer casing is two layers of metal foil and a layer of polypropylene. The heat pipe constructed in this manner is so a flexible that when one outside surface is covered with adhesive, the heat pipe can essentially be used as tape or a stick-on heat transfer surface which conforms to a body being cooled.

Flexible heat pipe

The disclosure is for a capacitor cooled by a heat pipe. The capacitor casing is constructed with an open tube inserted through the casing wall and into which is inserted a simple cylindrical heat pipe. The heat pipe may terminate at the casing wall which then acts as a heat transfer surface, or a portion of the heat pipe which extends beyond the end of the capacitor can be attached to an external heat transfer device, such as a heat conductive mounting plate or a cooling fin assembly.

Capacitor with heat pipe cooling

The invention is an integrated circuit cooler in which a heat spreader is mounted atop a weight sensitive integrated circuit package, and at least one heat pipe is attached to the heat spreader and to a cooling fin assembly remote from the heat spreader. To accommodate to the tolerances, the potential tilt of the installed integrated circuit package, and the weight of the fins, the heat spreader is mounted on the integrated circuit package using springs on posts attached to the circuit mounting board, and the heat pipe has an annealed section of the casing located between the heat spreader and the fins to relieve the potential stress on the thermal connection or the integrated circuit package. Another feature of the assembly is that the fins are mounted on the heat pipe using only spring clamps formed into the fins.

Stress relieved integrated circuit cooler

A heater which uses the electrolysis of a liquid to produce heat from electricity and transfers the heat from the electrolyte by means of a heat exchanger. One embodiment includes electrodes of nickel and platinum and an electrolyte of potassium carbonate with a heat exchanger immersed in and transferring heat from the electrolyte.

Electrolytic heater

An artery vapor trap. A heat pipe artery is constructed with an extension protruding from the evaporator end of the heat pipe beyond the active area of the evaporator. The vapor migrates into the artery extension because of gravity or liquid displacement, and cooling the extension condenses the vapor to liquid, thus preventing vapor lock in the working portion of the artery by removing vapor from within the active artery. The condensed liquid is then transported back to the evaporator by the capillary action of the artery extension itself or by wick located within the extension.

Cooled artery extension

An improved heat pipe with an external artery. The longitudinal slot in the heat pipe wall which interconnects the heat pipe vapor space with the external artery is completely filled with sintered wick material and the wall of the external artery is also covered with sintered wick material. This added wick structure assures that the external artery will continue to feed liquid to the heat pipe evaporator even if a vapor bubble forms within and would otherwise block the liquid transport function of the external artery.
