A heat exchanger includes tubes and a header tank. The tubes are arranged in parallel with each other, and fluid flows in the tubes. The header tank is disposed at end portions of the tubes in a longitudinal direction of the tubes and extends in a direction in which the tubes are arranged in parallel with each other to communicate with the tubes. The header tank includes a core plate, a resin tank main body part, and a resiliently-deformable sealing member. The tubes are joined to the core plate. The tank main body part is fixed to the core plate. The core plate includes a receiving part at which the sealing member is disposed. The tank main body part is fixed to the core plate with the sealing member clamped between an end part of the tank main body part on the core plate-side and the receiving part. The receiving part is disposed on a farther side from the tubes in the longitudinal direction of the tubes than the end portions of the tubes in the longitudinal direction of the tubes.

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.

The invention relates to a crimping tool for creating at least one connection through which coolant can be conducted between a tube connector. The invention also relates to a heat exchanger that has the connections formed using the crimping tool. The invention also relates to a method for creating the connections between the tube connectors and the tubes using the crimping tool.

The heat exchanger has tubes and a header tank that is located at an end of the tubes in a longitudinal direction and communicates with the tubes. The header tank has a core plate that connects to the tubes and a tank body that is fixed to the core plate. The core plate has a tube connection surface, a sealing surface, and an inclined surface that connects the tube connection surface and the sealing surface with each other. A distance between the tube connection surface and an end surface of the tubes in the longitudinal direction is different from a distance between the sealing surface and the end surface in the longitudinal direction by disposing the inclined surface to incline with respect to the longitudinal direction. The tubes connect to the tube connection surface and the inclined surface in a condition of being inserted to the tube connection surface and the inclined surface.

A liquid cooling radiator with impurities filtering includes a radiation fin module, a top cover and a bottom cover respectively enclosed at two opposite ends of the radiation fin module, liquid cooling heat pipes tightly inserted through the radiation fin module in communication between an enclosed top chamber in the top cover and an enclosed bottom chamber in the bottom cover for coolant circulation, and wire gauge filters individually mounted in the liquid cooling heat pipes for removing impurities from the circulating coolant and slowing down the flowing speed of the circulating coolant.

A tank portion defines a space therein and has an opening on one side. A foot portion is in a plate shape extending radially outward from a bottom end of the tank portion on the one side. A core plate covers the opening and has a base portion and a holder portion. The base portion is in an elongated rectangular plate shape having first and second long lateral sides and a short lateral side. The holder portion includes a first holder at the first long lateral side, a second holder at the second long lateral side, and a third holder at the short lateral side, each gripping the foot portion. All the first holder, the third holder, and the second holder are one piece continuously extending along the first long lateral side, the short lateral side, and the second long lateral side.

A method of manufacturing a heat dissipating device includes steps of providing a heat dissipating fin and a heat pipe. The heat dissipating fin includes a fin body, a through hole and a collar portion, with the through hole formed on the fin body, with the collar portion extending from a periphery of the through hole and having a first U-shaped protruding ear, with the first U-shaped protruding ear having a first opening, with the heat pipe having a heat dissipating end and a heat absorbing end, and with the heat dissipating end opposite to the heat absorbing end; inserting the heat dissipating end into the through hole and the collar portion; and punching the collar portion to shrink the first opening of the first U-shaped protruding ear, such that the collar portion fixes the heat dissipating end in a tight-fitting manner.

A evaporator provides an evaporator that includes an evaporator core, an evaporator tank attached to the evaporator core, at least one baffle incorporated into the evaporator tank, and multi-piece end plate assemblies attached to the tank. Each end plate assembly includes inner and an outer end plate layers. Each of the layers includes crimps. The inner end plate layer is preliminarily attached to the open end of the evaporator tank, during which proper alignment of the plate to the tank is made. The crimps of the inner end plate layer are crimped over. The outer end plate layer is then preliminarily attached to the inner end plate layer by crimping, thereby allowing preliminary attachment of the end plates to the tank to assure proper alignment prior to the end plates being fixed in position by a method such as brazing.

This document describes techniques for implementing phase-change cooling in a three-dimensional structure. A three-dimensional structure having three-dimensional curvatures is fabricated to include a phase-change chamber with a fluid in a saturated thermodynamic state. As part of fabrication, specific mechanisms may be included that create a thermo-mechanical network that improves thermal performance of the phase-change chamber and also provides structural integrity to the three-dimensional structure.

The heat exchanger has tubes and a header tank that is located at an end of the tubes in a longitudinal direction and communicates with the tubes. The header tank has a core plate that connects to the tubes and a tank body that is fixed to the core plate. The core plate has a tube connection surface, a sealing surface, and an inclined surface that connects the tube connection surface and the sealing surface with each other. A distance between the tube connection surface and an end surface of the tubes in the longitudinal direction is different from a distance between the sealing surface and the end surface in the longitudinal direction by disposing the inclined surface to incline with respect to the longitudinal direction. The tubes connect to the tube connection surface and the inclined surface in a condition of being inserted to the tube connection surface and the inclined surface.
