The present invention relates to a heat exchanger for changing the state of a fluid, for example an evaporator (1) for the fluid used in an air conditioning apparatus, the heat exchanger comprising tubular circuits (4) extending through fins (5), a distributor assembly for the fluid in a first state, connecting a fluid delivery tube to the input ends (6) of the said tubular circuits (4), and a collector assembly for collecting the fluid in a second state, the collector assembly being disposed so as to connect the outlet ends (8) of the tubular circuits (4) to a suction tube (10) and comprising a cylindrical part (11) arranged to form a coaxial extension of the suction tube (10) and being of larger radius than the suction tube.

Finned tube evaporator with collector assembly for joining plural tube

The connecting device for housing-shaped elements and the application thereof to the making of housings for air conditioning systems for vehicles is characterized in that one of the elements has a projecting lip (8) thereon, while the other element has a receiving flange for the projecting lip (8) bearing (14) and retaining (19, 21) means being provided alternately between the projecting lip (8) and the receiving flange.

Connecting device for housing-shaped elements

Device for mutual assembly of two parts which have to be occasionally disassembled, said two parts being produced from a synthetic material by moulding. There is provided on the outer wall of said parts at least one assembling group comprising a male portion on one of the parts and a female portion on the other part, the female portion defining a member for freeing the male portion and each of the two parts being formed with protrusions or noses for the subsequent engagement of resilient clips should there be a deterioration, even partial, of the assembling group during disassembly.
