The invention relates to a heat exchanger collector box () including: According to the invention, the sealing means () includes at least one support face () and is arranged on the collector plate () such that:

Collector box, sealing means and corresponding heat exchanger

A heat exchanger is disclosed. The heat exchanger includes a protective device, mutually parallel tubes through which a first fluid circulates, and perpendicular fins connecting two successive flat tubes, a second fluid circulating between said flat tubes by passing through said fins, the protective device being apertured so as to allow the circulation of the second fluid through the fins. The protective device includes fixing spikes which are inserted forcibly between the fins.

Heat exchanger comprising a protective device

The invention relates to a device for the thermal regulation of a motor vehicle battery pack () comprising at least one battery () contained in a housing (), the thermal regulation device comprising: at least one heat exchanger () in contact with the battery (), at least one elastic element () arranged in the bottom () of the housing () so as to hold the heat exchanger () against the battery (). An insulator () is interposed between the elastic element () and the heat exchanger ().

Battery pack thermal regulation device

The invention relates to a method for producing a heat exchanger tube () by bending a metal strip (), said tube () having an internal partition () formed by joining the ends of opposing edges (), said partition facing a projection () that extends into the heat exchanger tube () at a joining zone (). The method comprises the following steps: locally stamping the metal strip () in order to produce a projection at the joining zone (); and bending the metal strip () in order to form said heat exchanger tube (), such that the projection extends into the tube (). The invention also relates to such a tube () and to a heat exchanger () comprising a bundle of said tubes ().
