摘要:
The invention relates to a device for controlling the temperature of a motor vehicle battery module, comprising a heat exchanger (3) and a bundle of heat pipes (5) having at least one surface for making thermal contact with a battery of the motor vehicle and moreover with the heat exchanger (3). Said heat exchanger comprises at least one inner wall, making contact with said heat pipe surface, and at least one outer wall defining, with said inner wall, a space wherein a heat-transport fluid may flow. Said heat exchanger also comprises at least one input nozzle (20) and at least one output nozzle (21) for said fluid to flow therethrough. Said temperature control device is characterized in that said inner and outer walls are made of an aluminum or aluminum alloy sheet by a cold-forming operation and are assembled to one another by crimping, such as to form said fluid flow space.

The invention relates to a manifold (10) for a heat exchanger (1), comprising a cover (31), an intermediary plate (41), and a collector plate (51), said manifold (10) being intended to collect and distribute a fluid. According to the invention, the intermediary plate (41) defines a first fluid chamber (11) with the cover (31) and a second fluid chamber (12) with the collector plate (51), said second chamber being independent of the first (11). The invention also relates to a heat exchanger (1) comprising such a manifold (10) and to a method for producing such a manifold (10).

The invention relates to a tube (2) for a heat exchanger (1), including a strip (9) which is folded onto itself so as to define an inner space (10) of the tube (2), said strip (9) including a first edge portion and a second edge portion (15, 16) which are joined together so as to divide said inner space (10) into at least two channels. According to the invention, said first edge portion (15) has two separate portions, referred to as the first and second contact portions (18, 22), which contact the second edge portion (16), and a third contact portion (20), located between said first and second contact portions (18, 22), said third contact portion (20) being in contact with an area of the strip (9) opposite the second edge portion (10) with respect to the inner space (10) of the tube (2). The invention also relates to a heat exchanger (1) including such tubes (2).
