A heat exchanger may include a first collecting tank and a second collecting tank. The first collecting tank may include a first collecting pipe having a first collecting pipe opening for letting in a fluid and a second collecting pipe having a second collecting pipe opening for discharging the fluid. The second collecting tank may be arranged opposite the first collecting tank and may include a third collecting pipe and a fourth collecting pipe. The heat exchanger may also include a plurality of heat exchanger pipes fluidically connecting the first collecting pipe to the third collecting pipe and the second collecting pipe to the fourth collecting pipe. The heat exchanger may also include a separating wall arranged in each of the first collecting pipe and the second collecting pipe respectively dividing each into a first pipe section and a second pipe section.

A heat exchanger includes a heat transfer tube in which a plurality of tube body portions are arranged in a two-tier staggered pattern in a flow direction of heating gas, and a fin, wherein a plurality of cut-out recessed portions are provided in the fin by cutting out sites between first and second upstream side tube body portions, and each cut-out recessed portion extends toward a downstream side in the flow direction of the heating gas beyond the site between the first and second upstream side tube body portions so as to cross straight lines linking a center of a first downstream side tube body portion, which is positioned between the first and second upstream side tube body portions in the width direction, and respective centers of the first and second upstream side tube body portions. Thus, the temperature distribution of the fin is made even, thereby suppressing the generation of thermal stress, and as a result, distortion of the heat transfer tube is suppressed.

A tank assembly includes a heat exchanger tank and at least one side plate. Each heat exchanger tank includes a pair of foot portions and a pair of top portions. The foot portions are crimped to a corresponding header of a heat exchanger core. The top portions are configured with first engagement elements. The at least one side plate is disposed on at least one side of the heat exchanger core and is configured with second engagement elements. The second engagement elements engage with the corresponding first engagement elements to urge the heat exchanger tank towards the header.

An evaporator includes: a first surface which conducts heat; a heat medium in the evaporator, which vaporizes as a result of the heat absorbed; a condenser which liquefies the heat medium in a vaporized state; a vapour pipe which guides the heat medium in the vaporized state from the evaporator to the condenser; and a liquid pipe which guides the heat medium in a liquefied state from the condenser to the evaporator. A first opening of the vapour pipe and a second opening of the liquid pipe are disposed in different positions from each other in a first direction, and are disposed so as to open into a heat medium accommodation space inside the evaporator at different positions from each other in a second direction, and which is different to the first direction, and also at different positions from each other in a third direction which intersects the first surface.

The present disclosure relates to a fin heat exchanger, including a header, a set of tubes fluidly coupled to the header, and a mount configured to engage with and disengage from the set of tubes. The mount includes a fin section configured to extend between adjacent tubes of the set of tubes in an engaged mount configuration, and configured to be separated from the set of tubes in an unengaged mount configuration.

A heat exchanger component comprises a core portion with alternating first and second heat exchanging channels. A first ducting portion comprises first ducting channels for transfer a first fluid between a first fluid inlet/outlet and the first heat exchanging channels of the core portion, and second ducting channels for transfer of second fluid between a second fluid inlet/outlet and the second heat exchanging channels of the core portion. The first ducting channels direct the first fluid around the turn of at least 45 degrees and the second ducting channels direct the second fluid around a turn of at least 90 degrees. The first and second ducting channels are interleaved.

An end tab for a heat exchanger frame includes a plate, an end, an expansion portion, and a bent portion. The plate has a first width, and the end has a second width larger than the first width. The expansion portion increases the width from the first width to the second width. The bent portion connects the plate and the end and includes at least one window.

A heat exchanger includes a heat exchanger core, an intake tank, and a flow limiting portion. The heat exchanger core includes a stacked heat exchange portion, a distribution portion, and a collection portion. The stacked heat exchange portion defines first fluid flow paths through which a first fluid flows in a first direction, and second fluid flow paths through which a second fluid flows in a third direction. The distribution portion is configured to distribute the first fluid to the first fluid flow paths. The collection portion is configured to collect the first fluid from the first fluid flow paths. The flow limiting portion is configured to suppress an inflow of the second fluid from the intake tank into the distribution portion and the collection portion. The flow limiting portion and the intake tank are provided as a single component.

A heat exchanger includes a frame and a plurality of coil passes disposed within the frame. The plurality of coil passes is configured to direct a flow of a refrigerant therethrough to transfer heat with an air flow passing over the heat exchanger. The plurality of coil passes include a U-bend disposed between first and second linear portions of the plurality of coil passes to redirect the refrigerant from a first longitudinal end of the heat exchanger to a second longitudinal end of the heat exchanger. Additionally, a first plurality of fins is disposed on an outer surface the U-bend.

The present disclosure relates to a heat exchanger, for example an indirect charge air cooler for an internal combustion engine. The heat exchanger includes a heat exchanger block including a first channel system for a first fluid and a second channel system for a second fluid that is fluidically separate from the first channel system. Two opposite side parts and two opposite end parts are structured and arranged to fluidically delimit the second channel system. At least one frame part is connected with a respective edge of the two side parts and of the two end parts. An air inlet box is connected to the at least one frame part via a seal. The heat exchanger block has a width b1 and a height h1, and the seal has a width b.sub.2 and a height h.sub.2, where b.sub.1b.sub.2 and h.sub.1h.sub.2.
