A heat pipe is provided having a hollow body defining an interior vapor space, evaporator and condenser regions, a wick structure lining an inner wall of the hollow body, and a working fluid disposed in the hollow body, wherein a path for the working fluid in liquid state extends from the condenser region toward the evaporator region or wherein the wick structure extends along a direction from a first end of the hollow body toward the second end, and wherein the wick structure includes first and second regions that extend along the path or direction and that each have wick particles defining respective pore sizes that are different from one another.

Heat pipes having wick structures with variable permeability

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 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 heat exchanger for cooling a heat generating device including a base having a recess with a base coolant inlet opening and a base coolant outlet opening. A porous core is positioned within the recess of the base, and has a core coolant inlet opening and a core coolant outlet opening that are arranged in corresponding relation with base coolant inlet opening and a base coolant outlet opening so as to be in fluid communication. A porous gasket is pinched between the porous core and the base.

Porous media cold plate

A cooling member for a cautery surgical instrument such as a surgical forceps including a pair of elongate arms joined at an end so as to provide for resilient compressible movement of the arms between a normally open position and a squeezed closed position. The cooling member provides for conduction of heat away from an electrode tip and includes a first portion having a first diameter, and a second portion spaced away from the first portion that transitions from the first diameter to at least one smaller diameter section. A socket is disposed within each arm of the forceps. The socket includes a longitudinal blind hole that is sized so as to releasably receive the smaller diameter section of the second portion, and a catch for engaging a portion of the arm.

Cooling element for electrosurgery

A cooling system has a heat sink having a plurality of fins. A fan is positioned near the heat sink to blow air between the fins. A flow converging device is positioned between the fins and the fan, to cause air from the fan to converge on a predetermined region of the heat sink. The flow converging device may be, for example, a plurality of wedges or a body having a frustum shaped opening through the body.

Heat sink with converging device

The disclosure is for an easily assembled heat exchanger using an internal porous metal pad. The heat exchanger is constructed of two halves attached at their heat transfer surfaces. Each half includes a pan shaped casing, a pad of sintered porous metal, a manifold block with channels, and a lid. The porous pad is mounted between the heat transfer surface of the casing and the manifold. The lid includes input and output fluid holes which are connected to sets of alternating channels in the manifold block, so that adjacent channels are isolated from each other and are connected to only either the input or the output holes so that the fluid must flow through the pad. An alternative embodiment has the casings of the two halves formed as a single part.

Compact fluid to fluid heat exchanger

The apparatus is an easily assembled, fluid cooled, single phase heat sink. The heat sink is constructed of only four simple parts, a pan shaped casing, a simple thermally conductive porous pad, a manifold block with channels, and a lid. The lid includes input and output fluid holes which are interconnected to sets of alternating channels in the manifold block, so that adjacent channels are isolated from each other and are connected to only either the input or the output holes. Thus, the only access between the adjacent input and output channels is through the porous pad which is sandwiched between the manifold block and the bottom of the casing. Fluid flow through the porous pad thereby cools the entire bottom of the casing which is held in heat transfer relationship with a heat source.
