A heat exchanger according to one embodiment includes: a heat exchange core; a shell provided to surround the heat exchange core; and a first partition wall that is provided in a space surrounded by an outer surface of the heat exchange core and an inner surface of the shell, and partitions the space into a first header space communicating with the heat exchange core and a second header space communicating with the heat exchange core. The first header space and the second header space are adjacent to each other, separated by the first partition wall.

A plate heat exchanger includes a plurality of heat transfer plates stacked together and each having openings at four corners thereof. The heat transfer plates are partially brazed together such that a first flow passage through which first fluid flows and a second flow passage through which second fluid flows are alternately arranged with one of the heat transfer plates disposed therebetween, openings at the four corners being connected forming first headers through which the first fluid enters and is discharged and second headers through which the second fluid enters and is discharged. At least one of two heat transfer plates between which the first flow passage or the second flow passage is disposed is formed by a pair of metal plates stacked together. The metal plate adjacent to the second flow passage is thinner than the metal plate adjacent to the first flow passage.

A heat exchanger includes a core. The core includes a first layer and a second layer. The first layer includes a first plurality of fluid inlets. The second layer includes a second plurality of fluid inlets. The heat exchanger also includes a fluid header attached to the core adjacent the first plurality of fluid inlets and the second plurality of fluid inlets. The fluid header includes an inlet, an outlet, a plenum between the inlet and the outlet, and a flow control mechanism within the plenum. The flow control mechanism selectively directs fluid through the first plurality of fluid inlets, through the second plurality of fluid inlets, or through both the first plurality of fluid inlets and the second plurality of fluid inlets.

A heat exchanger for heating a fluid flowing through a pipe using a combustion gas includes: a body including open upper and lower ends and having a space formed therein to allow the combustion gas to pass therethrough; a combustor formed in an upper portion of the space in which combustion of the combustion gas occurs; a heat exchange portion formed below the combustor and provided with a heat exchange pipe configured to heat an internal fluid by using the combustion gas; and a heat return pipe provided outside the space so as to be in contact with an outer surface of the body, wherein the combustor and the heat exchange portion may be unitarily formed, and the body in which the combustor is formed includes a concave portion protruding concavely inward so as to correspond to a shape of an outer circumferential surface of the heat return pipe.

A header box includes a first bottom plate and an unperforated cover plate. The first bottom plate includes a first surface and a second surface opposite to the first surface. The first bottom plate is of a one-piece configuration. The first surface is recessed inwardly to form a straight first hole extending along a length direction. The second surface is recessed inwardly to form at least two straight second holes extending along a width direction perpendicular to the length direction. The first hole is communicated with the at least two second holes. The cover plate is connected to the first surface to block an opening of the first hole on the first surface. A heat exchanger having the header box is also disclosed.

A compact heat exchanger unit within an air conditioning apparatus for a vehicle, and a condenser region for the condensation of refrigerant is formed as a heat exchanging surface, and a high-pressure-refrigerant collector region as a refrigerant collector is formed in the integrated form as a plate packet of a heat exchanger within a plate heat exchanger.

A plate heat exchanger arrangement, which includes at least a first plate pack and a second plate pack arranged adjacent to each other inside the outer casing, and the first plate pack has a diameter, defined by the outer edges of the heat exchange plates, which is greater than a diameter of the second plate pack.

A heat exchanger for a motor vehicle includes a seal and a core. The core includes a first groove formed in a first side and a second groove formed in an opposing second side. The first groove and the second groove are each configured to receive a portion of the seal to secure the seal to the core. The seal includes a cross member and a pair of uprights extending from opposing ends of the cross member, wherein the cross member and the uprights each include a sealing element. The uprights further include a rail extending from the upright and configured to be received in the groove of the core. The core further includes an integrated shear panel formed at opposing ends thereof.
