The present invention relates to a heat exchange device () for a motor vehicle including a heat exchanger () with first and second collector plates (), first and second header boxes () attached to the collector plates () and a bundle () of pipes () extending between the first and second collector plates (). Each of the collector plates () forms a groove () between the pipes () of the pipe bundle () and a lateral end () of the respective collector plate (). A perforated protective device () for the pipes () is attached to the heat exchanger () using attachment means () bearing against the inside of the grooves () in the first and second collector plates ().

Heat exchange device including a protection device

The present invention consists in a thermal module () for a motor vehicle, comprising a main radiator () and at least one auxiliary heat exchanger () mounted on the main radiator () by means of a junction member () disposed between the main radiator () and at least one first auxiliary heat exchanger (), The junction member () is principally formed of at least two shaft bearings () attached to the first auxiliary heat exchanger () and nested inside respective open flanges () formed on one of the lateral sides () of the main radiator (). Secondarily, the junction member () carries a plurality of auxiliary heat exchangers () fixed to one another in staggered succession and composing a thermal submodule mounted on the main radiator () by means of the junction member ().

Device for assembling a heat exchanger of an air-conditioning apparatus with a radiator for cooling the engine of a motor vehicle

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 concerns an attachment device () for a heat exchanger () comprising a core () for exchanging heat between a first fluid and a second fluid, said core () being provided with collectors () for the first fluid, said exchanger () comprising a cylinder (), said cylinder () and one of said collectors () allowing the passage of said first fluid from one to the other, said attachment device () comprising a body, which is set up in order to close said cylinder (), and an extension which allows the core () to be secured to a holder (). The invention also concerns a cylinder () which comprises such an attachment device (), a heat exchanger () which comprises such a cylinder () and a heat exchanging module which comprises such a heat exchanger ().
