Each of the first fluid passages in the second level is in fluid communication with the inlet and at least one of the first fluid passages in the third level, and each of the second fluid passages in the second level is in fluid communication with the outlet and at least one of the second fluid passages in the third level.

A heat exchanger plate for provides heat transfer between a first flow along a first flowpath and a second flow along a second flowpath. The heat exchanger plate comprised a body having: a first face and a second face opposite the first face; a leading edge along the second flowpath and a trailing edge along the second flowpath; a proximal edge having at least one inlet port along the first flowpath and at least one outlet port along the first flowpath; and at least one passageway along the first flowpath. Along a proximal portion, the first face and the second face converge at a first angle. Along a distal portion, the first face and the second face converge at a second angle less than the first angle.

The invention relates to a heat exchanger for a battery, in particular for a hybrid drive, with connections for the inflow and outflow of a heat exchange medium and with a frame which is connected on both sides with film walls to form a pouch through which a flow can pass, wherein the frame comprises flow guiding elements The invention is characterised in that the frame comprises a separating plate with two parallel lateral surfaces, wherein the separating plate divides the pouch into a first chamber and a second chamber which are delimited in a fluid-tight manner by the lateral surfaces and the respective film walls, wherein in each of the lateral surfaces a channel field of parallel flow channels is formed, the inflow side of which is fluidically connected via a distributor channel and the outflow side of which is fluidically connected via a collecting channel to the respective connections. The invention also relates to a battery with at least one heat exchanger, a vehicle with one such battery as well as a manufacturing method for the heat exchanger.

A heat exchanger comprises a first header, a second header, a plurality of tubes, and a flow reducer. The first header is connected to a hot fluid inlet and to a cold fluid outlet, so that the first header comprises a hot region and a cold region, separated by a wall. Each of the plurality of tubes provides fluid communication between the first and second headers, including one tube located next to the wall in the hot region of the first header, being called “hot end tube” , and one tube located next to the wall in the cold region of the first header, being called “cold end tube” .
