    摘要： A heat exchanger including a first reservoir, a second reservoir, and a heat tube including a body extending between the first reservoir and the second reservoir, where the heat tube defines a working region having a cross-sectional shape with an exterior wall enclosing a channel therein that is in fluid communication with the first reservoir and the second reservoir. The heat tube includes a curvilinear tube axis extending the axial length of the working region, and where the body of the working region includes the cross-sectional shape extruded along the curvilinear tube.

    摘要： A heat exchanger having: a first heat exchanger core including a first sub-heat exchanger core and a second sub-heat exchanger core, wherein the first sub-heat exchanger core and the second sub-heat exchanger core includes heat exchange tubes, the heat exchange tubes of the first sub-heat exchanger core and the second sub-heat exchanger core are connected to each other, and orthographic projections of the first sub-heat exchanger core and the second sub-heat exchanger core on a plane where the second sub-heat exchanger core is located at least overlap partially; and a second heat exchanger core including a heat exchange tube, wherein the heat exchange tube of the second heat exchanger core is connected to the heat exchange tubes of the first sub-heat exchanger core and the second sub-heat exchanger core is disclosed. At the same incoming wind speed, the ratio of the wind resistance of the heat exchanger to the air passing through the first heat exchanger core to the wind resistance of the heat exchanger to the air passing through the second heat exchanger core is less than a predetermined value. By using the heat exchanger according to the present invention, the performance of the heat exchanger can be improved.

    摘要： A heat exchanger with increased heat transfer capability includes first and second end plates, tubes extending between the first and second end plates and fins disposed between the tubes. The heat exchanger is disposable within and differs in shape from a space defined between first and second walls such that corners of the first end plate abut the first wall and a point of the second end plate abuts the second wall, the first wall diverges from the corners of the first end plate to define a first open region and the second wall diverges from the point of the second end plate to define second open regions. At least one of the first end plate and the second end plates includes enhancements fluidly communicative with the at least one corresponding one of the first open region and the second open regions.

    摘要： A cylindrical header of a heat exchanger includes a central member, front-side and rear-side members extending longitudinally on front and rear sides of the central member to form front-side and rear-side spaces along with the central member. The central member has a first flange covering a front-side-member-first-end part and a rear-side-member-first-end part from outside when viewed in cross-section, and a second flange covering a front-side-member-second-end part and a rear-side-member-second-end part from outside when viewed in cross-section. The front-side member is joined to the central member with the front-side-member-first-end part facing an inner surface of the first flange, and the front-side-member-second-end part facing an inner surface of the second flange. The rear-side is joined to the central member with the rear-side-member-first-end part facing an inner surface of the first flange, and the rear-side-member-second-end part facing an inner surface of the second flange.
