A battery cooler comprises a refrigerant filling chamber, a refrigerant inflow passage, and a refrigerant outflow passage. The refrigerant filling chamber is sandwiched between opposed battery unit cells and is arranged at a position for receiving heat of the unit cells. The refrigerant inflow passage is connected to a lower portion of the refrigerant filling chamber. The refrigerant outflow passage is connected to an upper portion of the refrigerant filling chamber. The refrigerant filling chamber has at least one joint part joining partially and mutually opposed wall surfaces so as to suppress expansion and deformation of these surfaces caused by the pressure of the refrigerant. An outflow side wall surface rises from a bottom surface of the refrigerant filling chamber toward a connection part of the refrigerant outflow passage. The outflow side wall surface is provided with an inclined surface directed downward from a horizontal direction.

A flow path tube of a heat exchanger includes an inner fin having a meander shape in which a one-side top part and an other-side top part are alternately arranged via an intermediate part. The intermediate part includes a communication part with a communication port that communicates the adjacent fine flow paths. A one-side wall part is extended from the one-side top part, which is adjacent on one side, to the communication part and separates the adjacent fine flow paths. An other-side wall part is extended from the other-side top part, which is adjacent on the other side, to the communication part and separates the adjacent fine flow paths. An edge of the one-side wall part is formed such that an edge of the other-side wall part is shifted in parallel in the longitudinal direction of the flat cross sectional shape of the flow path tube.

Heat exchanger comprising at least a first plate (11) and at least a second plate (12) overlapping and reciprocally joined to each other in correspondence with respective coupling surfaces (13). Between the coupling surfaces (13), at least one passage channel (14) for a heat-carrying fluid is made, by deforming at least one of the two plates (11, 12).

The present disclosure provides a liquid-cooling type double-sided cooler, including a first cooling portion and a second cooling portion. In the liquid-cooling type double-sided cooler, another end of the first cooling portion is formed with a first communication hole that is configured to penetrate the first cooling liquid path and an outside of the first cooling portion, another end of the second cooling portion is formed with a second communication hole that is configured to penetrate the second cooling liquid path and an outside of the second cooling portion; and the first cooling portion and the second cooling portion are positioned such that the first communication hole and the second communication hole face each other, and the first cooling liquid path and the second cooling liquid path are connected with each other.

The method can further include generating heat in the first coupling elements at the same time and at a temperature sufficient to generate a first plurality of respective couplings between adjacent sheets of adjacent heat exchanger units about adjacent first ports and without a coupling being generated between the first and second sheets of a given heat exchanger unit.

An inner fin is a wave fin having board portions extending in a pipe longitudinal direction and a top portion connecting the board portions located adjacent with each other. The wave fin has a wave-shaped cross-section perpendicularly intersecting a pipe longitudinal direction, and the board portion is bent into a waveform extending in the pipe longitudinal direction when seen from a pipe layering direction. A wave pitch WP [mm], a wave depth WD [mm], and a passage width H [mm] are set to satisfy relationships of 2.2≤WP/WD≤4.28 and 0.5≤WD/H≤1.8.

A cooler includes a cooling pipe having a cooling surface in contact with a heat-exchanged component, and a refrigerant passage. A pair of outer passages are formed between a pair of opposed inner wall surfaces which are located at both ends of an inner wall surface of the cooling pipe in a perpendicular direction and which constitute the refrigerant passage, and a pair of partition walls that are located at both ends of an inner fin in the perpendicular direction. At least one flow-regulating rib is formed in the refrigerant passage to project into the refrigerant passage at a position inward of the pair of outer passages in the perpendicular direction and at a position outward of an inflow hole and a discharge hole in the perpendicular direction as well as at a position outward of the inner fin in an arrangement direction and at a position inward of the inflow hole and the discharge hole in the arrangement direction.
