The invention relates to a header tank () for a mechanically assembled heat exchanger, notably for a motor vehicle, said exchanger () comprising a mechanically assembled heat-exchange core bundle () and comprising at least one row of tubes () with two end tubes () one at each end of said at least one row, the tubes () respectively comprising an end () intended to open into an interior volume of the header tank (). According to the invention, the header tank () comprises at least one end stop () configured to be positioned facing an internal surface of the end () of an associated end tube () and to collaborate with said internal surface in such a way as to prevent said tube () from moving in the direction of the interior volume of the header tank ().

Header tank and corresponding heat exchanger

The invention relates to a heat exchanger comprising: With the fin () having a flat rectangular overall shape, the ratio between the number of louvers () and the width of the fin () is between 0.73 and 1.13.

Fin heat exchanger comprising improved louvres

A thermal battery having an enclosure including a fluid inlet and outlet. Between the inlet and outlet are tubes of encapsulated phase-change material. The tubes are arranged parallel to each other, and include radial spacers for spacing the tubes apart, such that the radial spacers of each of any two given contiguous tubes are longitudinally and radially offset from one another so as to allow fluid to circulate.

Thermal battery with encapsulated phase-change material

The present invention relates to a thermal battery () comprising an enclosure () comprising a fluid inlet and outlet and comprising within it tubes () of encapsulated phase-change material, said thermal battery () further comprising a device () for holding and spacing the tubes () of encapsulated phase-change material, said holding and spacing device () being arranged between the tubes () themselves and between the tubes () and the enclosure (), said holding and spacing device () being porous.

Thermal battery with encapsulated phase-change material and associated production method

The invention concerns a header () for a heat exchanger of a motor vehicle, configured to receive heat exchange tubes (). The header comprises:

Header for a heat exchanger of a motor vehicle

A method is disclosed for producing a heat exchanger, in particular for a motor vehicle, a method whereby fluid circulation tubes () are inserted into through holes in heat exchange fins () and the fluid circulation tubes () are subjected to expansion in such a way as to expand a contour () of the tubes () to ensure contact with the fins () at the through holes and, additionally, for at least one of the tubes (), to deform a concave portion () of the contour () of the tube or tubes (), in such a way as to correspondingly deform the through holes. A device for implementing the method and an exchanger obtained by the method are also disclosed.
