A new system for and a method of deploying a heat exchanger pipe. A bore hole is drilled from an access ditch location to a terminal ditch location using a piloted drill head powered via an umbilical attached to the piloted drill head. A casing is attached to the piloted drill head and disposed about the umbilical into the bore hole from the access ditch location to the terminal ditch location. At the terminal ditch location, the piloted drill head is removed from the casing and the umbilical and a heat exchanger pipe is attached to the umbilical. The umbilical is withdrawn from within the casing deployed in the bore hole to pull the heat exchanger pipe into the casing. The casing is then withdrawn from the bore hole leaving the heat exchanger pipe in the bore hole.

A header plate includes slots to receive heat exchange tubes of a heat exchanger. Each slot includes a lip extending in a direction of the tubes. Each slot has straight sides and corners. At least two tabs extend from each lip. One tab is on one side of each lip, and another tab is on an opposite side of each lip. Tabs are absent from the corners of the lip. Each tab is turned out from the lip so that the tabs on the lip act as a lead in for a tube entering the slot. Each slot has two long sides opposite one another. At least one tab is on each long side of the lip.

An apparatus for forming and sealing a duct member for use in an air handling system. At least one work station accommodates a work piece, which is generally a cylindrical tube.

A cooling block assembly for cooling a heat-generating electronic component includes: an upper block portion defining at least one internal fluid conduit and having a lower surface configured to face toward the heat-generating electronic component; a boss spaced from the lower surface and having a thermal transfer surface configured to be in thermal contact with the heat-generating electronic component, the thermal transfer surface being offset from the lower surface, a periphery of the thermal transfer surface being smaller than a periphery of the upper block portion, the periphery of the thermal transfer surface being contained within the periphery of the upper block portion in a projection thereof on a plane parallel to the thermal transfer surface; and heat distributing devices for distributing heat through a phase change of a working substance contained therein, each heat distributing device being disposed partially between the boss and the lower surface.

A thin heat pipe structure and a manufacturing method thereof. The thin heat pipe structure includes a tubular body and a mesh body. The tubular body has a chamber and a working fluid. At least one first channel and at least one second channel are formed on an inner wall face of the chamber. The first and second channels extend to intersect each other. The mesh body is attached to the inner wall face of the chamber. The thin heat pipe structure is able to transfer heat in both axial direction and radial direction. By means of the manufacturing method, the heat pipe can be slimmed and the ratio of good products can be greatly increased.

A heat sink structure and a manufacturing method thereof. The heat sink includes a main body and multiple radiating fins each having a folded root section. The main body has multiple connection channels formed on a circumference of the main body. The multiple radiating fins are placed in a mold. A mechanical processing measure is used to high-speed impact the main body so as to thrust the main body into the mold. Accordingly, the folded root sections of the radiating fins are relatively high-speed thrust into the connection channels of the main body to tightly integrally connect with the main body.

A radiator includes a tube that has a flattened-shape, the tube including an internal flow channel that allows a coolant to flow through the internal flow channel; and a tank that includes an insertion port into which a joint end portion of the tube is inserted so that the tank and the tube are joined to each other, wherein the tube includes an outer-peripheral-wall extending in a direction perpendicular to a thickness direction of the tube, and bend depressions that are bent toward the internal flow channel in a concave shape are formed in at least a region of the outer-peripheral-wall adjacent to the joint end portion, the bend depressions extending along the internal flow channel, and the bend depressions are deformed in a width direction of the tube so that the width of the joint end portion is the same as the width of the insertion port.
