A heat exchanger includes a bag body including, in an interior of the bag body, a heat exchange path through which a heat exchange medium flows; and a base body including, in an interior of the base body, a supply path that communicates with one end of the heat exchange path and is configured to supply the heat exchange medium to the heat exchange path, and a recovery path that communicates with another end of the heat exchange path and is configured to recover the heat exchange medium. The bag body includes a front sheet, a rear sheet opposite to the front sheet, an inflow port through which the heat exchange medium flows in, an outflow port through which the heat exchange medium flows out, and an occlusion prevention member provided over a surface of the front sheet.

A separating element (10a, 10b) adapted to be positioned in connection to a heat exchanger unit (1, 1a, 1b, 1c) of a sectioned heat exchanger (100) is disclosed. The separating element (10a, 10b) has first openings (11a, 11b) adapted to align with first heat exchanger openings (3a, 3b) forming inlets of a first flow path (A) and a second flow path (B), respectively, through the heat exchanger unit (1, 1a, 1b, 1c). The separating element (10a, 10b) further includes second openings (11c, 11d) adapted to align with second heat exchanger openings (3c, 3d) forming outlets of the first flow path (A) and the second flow path (B), respectively. The first openings (11a, 11b) are formed with first valves (12a, 12b) adapted to close for fluid flow to the first (A) and/or the second (B) flow path through the heat exchanger unit (1, 1a, 1b, 1c), and the second openings (11c, 11d) are formed with second valves (17a, 17b) adapted to close for fluid flow from the first (A) and/or second (B) flow path. The first valves (12a, 12b) are formed with valve stems (13a, 13b), each operated by an actuator (14a, 14b), and the second valves (17a, 17b) are connected to the same valve stems (13a, 13b) as the first valves (12a, 12b), thereby providing coordinated control of the first valves (12a, 12b) and the second valves (17a, 17b).

A cooling component for cooling objects includes a metal profile, forming a heat sink. The profile has multiple parallel medium channels for the flow of cooling medium therethrough, each of which is delimited by a circumferential medium channel wall formed by the profile. The cooling component includes a first connection part made of plastic, which is connected to the profile in a fluid-tight manner, with inlet or outlet opening, via which cooling medium is able to be fed to the cooling component or via which cooling medium is able to be discharged from the cooling component. In the region of the first connection part, the circumferential medium channel wall of at least one of the parallel medium channels has at least one through opening, via which the medium channel is fluidically connected to the inlet or to the outlet opening of the first connection part.

A heat exchange plate having flow paths through which a heat medium flows and an elongated rectangular plate shape including: an upper and lower walls covering the flow paths from both sides of the heat exchange plate in a plate thickness direction; and partition walls connecting the upper and lower walls in the plate thickness direction to partition the flow paths. The heat medium flows through the flow paths is a longitudinal direction of the heat exchange plate. At least one end portion of the heat exchange plate in the longitudinal direction closes the plurality of flow paths. The upper and lower walls, and partition walls constituting the closing portion are compressed in the plate thickness direction. The heat exchange plate further includes: a brazing portion filling a gap present between the upper wall and lower walls, and the partition walls constituting the closing portion.
