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.

An air conditioner fin assembly automatic tube expansion system based on a digital bus includes: a tube expander, a fin assembly load-fetching device, a fin accompanying tooling, interactive exchange trays, a controlled material trolley, and an electrical control device. The fin assembly load-fetching device includes an X-coordinate driving mechanism, a Y-coordinate driving mechanism, a Z-coordinate driving mechanism, and a mechanical arm including a coordinate rotating mechanism assembly and a load-fetching mechanical arm. The fin accompanying tooling is configured between the tube expander and the fin assembly load-fetching device. At least two interactive exchange trays are configured and clamped to the fin accompanying tooling. At least two controlled material trolleys are included and docked on an inner or an external side of the fin assembly load-fetching device.

A method of forming a flat bar is provided. A tube is provided having an inside surface and an outside surface. The outside surface of the tube can be clad with a nickel or stainless alloy material. A helix shaped strip can be cut from the tube. The helix shaped strip can be uncoiled to form an uncoiled strip, and the uncoiled strip can be straightened and flattened to meet mill standards.

In various embodiments, laser systems feature beam emitters thermally coupled to heat sinks comprising, consisting essentially of, or consisting of a metal-matrix composite of a thermally conductive metal and a refractory metal. At least a portion of the surface of the heat sink is treated to form a depleted region, and a diamond coating is deposited within and/or over the depleted region. The depleted region is substantially free of the thermally conductive metal or contains the thermally conductive metal at a concentration less than that of the body of the heat sink.

An electronic equipment enclosure includes a frame structure and a customizable side air dam kit. The frame structure includes a front frame, a rear frame, front-to-back frame members connecting corners of the front and rear frames together, reinforced bracket structures located near ends of the cross members, and extruded horizontal mounting rails parallel to, but inward from, the front-to-back frame members. The ends of the horizontal mounting rails are connected to the reinforced bracket structures. Panels are installed in longitudinal slots in the front-to-back frame members and horizontal mounting rails, each of which is extruded. The customizable side air dam kit includes a framework of horizontal and vertical frame pieces, adapted to connect to the frame structure, and a customizable air dam panel supported by the framework. A plurality of the frame pieces are provided to an installer for use in constructing the framework to fit the specific frame structure.

A flat tube with a wall made of a shaped first sheet metal strip which forms two fluid chambers, wherein the two fluid chambers are arranged spaced apart from one another and wherein the two fluid chambers are connected spaced apart from one another by a web wherein the flat tube has two tube ends in its tube longitudinal direction, wherein the web has a recess by means of a cutout at at least one tube end.

A method includes providing a first metal sheet and a second metal sheet, printing patterns of a plurality of obstructers, a plurality of channels, an evaporator channel, a condenser channel, and a connecting channel on the first metal sheet, bonding the first metal sheet and the second metal sheet to each other, separating the first metal sheet and the second metal sheet from each other to form the plurality of channels, the evaporator channel, the condenser channel, and the connecting channel by introducing a fluid between the first metal sheet and the second metal sheet, introducing working fluid in the plurality of channels, and sealing the first metal sheet and the second metal sheet.

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.
