The heat exchanger includes a first header, a second header, a third header, a fourth header, a heat exchange tube including a first heat exchange tube and a second heat exchange tube alternately arranged in a length direction of the header, and fins. The first heat exchange tube or the second heat exchange tube or both has a bent section and includes a first section, a middle section, and a second section, and the heat exchanger includes a first part including the first section, a middle part, and a second part. The middle part of the heat exchanger includes the middle section and the fins, and air flowing through the heat exchanger passes through the middle part and then the first part, or passes through the first part and then the middle part.

A system and method for attaching two automotive cooling modules together is provided. A first cooling module has a tab extending outwardly therefrom, the tab having an aperture extending therethrough. A second cooling module has a backwall and one or more flexible prongs extending in a first direction from the backwall and through the aperture of the tab in a snap-fit attachment. The tab is spaced from the backwall when the one or more prongs are attached to the tab. The second cooling module also has a boss extending in a second direction from the backwall, wherein the boss has a receptacle aligned with the aperture of the tab. In the event of damage to the one or more prongs, the one or more prongs can be removed, and a fastener can be fastened through the aperture of the tab and into the boss.

A heat exchanger is provided. The heat exchanger includes a first wall manifold. The heat exchanger further includes a second wall manifold spaced apart from the first wall manifold. The heat exchanger further includes a plurality of vanes that extend generally circumferentially between the first wall manifold and the second wall manifold. The heat exchanger further includes a plurality of fluid circuits defined within the heat exchanger. Each fluid circuit in the plurality of fluid circuits includes an inlet channel portion and an outlet channel portion defined within the first wall manifold. A return channel portion defined within the second wall manifold. At least one passage portion of a plurality of passage portions defined within each vane of the plurality of vanes. The at least one passage portion extends between the return channel portion and one of the inlet channel portion and the outlet channel portion.

A micro channel type heat exchanger in which a first heat exchange module and a second heat exchange module are stacked, the micro channel type heat exchanger including a plurality of flat tubes disposed within the first heat exchange module and the second heat exchange module, and a heat blocking member configured to form a heat blocking space by separating the first heat exchange module and the second heat exchange module, wherein the heat blocking member forms a heat blocking space between the first heat exchange module and the second heat exchange module that minimizes heat conductivity and improves thermal exchange performance of the heat exchanger.

Heat exchanger (2, 3) for a refrigerant circulation circuit comprising at least one connection flange (5, 6) fixed to a lateral surface of said heat exchanger (2, 3), characterized in that the connection flange (5, 6) comprises a circulation channel within its structure and a transverse mechanical fixing zone (21, 22) able to cooperate with another transverse mechanical fixing zone (21, 22) of another connection flange (5, 6) of another heat exchanger (2, 3).

The invention also claims a heat exchange system for a vehicle comprising two such heat exchangers (2, 3) and the respective connection flanges (5, 6) of which are able to cooperate with one another.

A split bay forced draft air-cooled heat exchanger includes first and second bay sub-assemblies. Each sub-assembly includes a tube bundle, a plenum half positioned under the tube bundle and base beams supporting the tube bundle and the plenum half. Also included is a fan assembly having a fan, a fan motor and a drive assembly and a machinery mount upon which the fan assembly is mounted. The machinery mount is attached to base beams of the first bay sub-assembly and is configured to removably attach to base beams of the second sub-assembly with the fan configured to force air into a plenum made up of the plenum halves and across the tube bundles.
