A heat exchanger core includes a first sheet having a first side and a second side opposite to the first side, a second sheet opposing the first side of the first sheet, and a first fin extending between the first side of the first sheet and the second sheet. The first fin defines first channels that extend in a first direction, the first fin including a first slot that extends at a first angle between thirty degrees and sixty degrees from the first direction and fluidly connects at least two of the first channels together.

A method for producing heat exchangers having at least two fluid circuits each having channels, including the following steps: producing one or a plurality of elements of a first fluid circuit, each element having at least two metal plates, at least one of which has first grooves; stacking the at least two metal plates of each element in such a way that the first grooves form the channels of the first circuit; assembling each element of the first circuit by diffusion welding between the two stacked metal plates; producing one or a plurality of elements of at least one second fluid circuit, each element of the second circuit having at least a portion of the channels of the second circuit; assembling, either by diffusion welding, or by brazing, or by diffusion brazing between the element or elements of the first circuit and the element or elements of the second circuit.

A heat exchanger core includes a first fin passage. A first frame surrounds a perimeter of the first fin passage. The first frame includes a plurality of bars configured to be removable from the first frame.

An indirect evaporative cooling air-conditioning device, for blowing cooled air into a room, includes an air intake, for collecting air to be cooled; a plurality of plates forming a stack; and a ventilation system. Each plate has a dry face opposite a wet face, which is to be kept wet with water. Each plate is intended to be cooled by water evaporation from the wet face. Two adjacent plates are spaced from each other, along a transverse axis, to form a channel, either dry or wet. A dry channel is delimited by two dry faces of the adjacent plates. A wet channel is delimited by two wet faces of the adjacent plates. Each wet channel includes several wet outlets distributed along a lateral axis, and/or each dry channel includes several air inlets distributed along the lateral axis, which is perpendicular to a longitudinal axis and to the transverse axis.

The present invention relates to a heat exchanger, and more particularly, to a heat exchanger in which a branch pipe is disposed adjacent to a coolant discharge port, which may miniaturize an entire heat exchange system and improve packageability.

In some examples, a heat exchanger includes a first flow channel having a first flow channel inlet and a first flow channel outlet. The heat exchanger also includes a second flow channel having a second flow channel inlet and a second flow channel outlet. A fin may separate the first flow channel from the second flow channel. The fin may define at least one aperture configured to allow fluid to flow between the first flow channel and the second flow channel if one of the first flow channel inlet or second flow channel inlet becomes constricted through a buildup of foreign object debris.

A heat exchanger for allowing heat to be exchanged between a first fluid and at least one other fluid comprises: a core comprising: at least one flow path; a manifold in communication with the at least one flow path; wherein the manifold comprises a void formed in the core; and the manifold comprises end caps, wherein at least one of the end caps is a non-flat end cap.

A heat exchanger includes: the pair of the oil holes being positioned on an outer edge of one of the core plates, being positioned at symmetrical positions with respect to the center of the one of the core plates to sandwich the center of the one of the core plates, and being positioned to sandwich one of the fin plates along the first reference line, and the pair of the coolant holes being positioned on the outer edge of the one of the core plates, being positioned at symmetrical positions with respect to the center of the one of the core plates to sandwich the center of the one of the core plates, and being positioned to sandwich the one of the fin plates along the first reference line.

A heat dissipation device includes a heat dissipation piece, heat conduction plates, a rod piece and a switch. The heat conduction plates are connected to the heat dissipation piece and spaced apart from and arranged parallel to each other so as to define accommodating spaces. Each heat conduction plate has a free end away from the heat dissipation piece, and the free end has a through hole. The rod piece has a first end and a second end opposite to each other, the rod piece penetrates through the through holes, and the second end has a limitation portion. The switch has a cam portion pivoted to the first end. When the switch is pivoted with respect to the heat conduction plates, the cam portion drives the rod piece to move among the through holes, making the limitation portion to press against or be separated from the heat conduction plates.

A fuel cell apparatus includes a fuel cell module including a housing and a fuel cell housed in the housing, the fuel cell generating electric power with use of a fuel gas and an oxygen-containing gas; and a heat exchanger which carries out heat exchange between a medium and exhaust gas from the fuel cell module, the heat exchanger being arranged laterally to the housing.
