Abstract
An expansion tank and water box device for a heat exchanger with a nest of parallel tubes, such as a radiator of a motor vehicle, in which the water box housed inside the expansion tank is maintained by the assembly of the tank with the hollowed plate through which extend the ends of the tubes. Ribs are interposed between the water box and the expansion tank. Said ribs depend, for instance, from the expansion tank.
Claims9
In a heat exchanger including a plurality of substantially parallel heat exchanging tubes and a collector plate having a plurality of openings, each of said openings being traversed, respectively, by an end of one of said tubes for the purpose of mounting the same, the combination of:
- (a) an expansion tank;
- (b) said expansion tank having a peripheral edge portion sealingly connected to said collector plate;
- (c) a water box housed inside said expansion tank, said water box comprising a partition separate from said expansion tank;
- (d) said partition of said water box dividing the space in said expansion tank into a collector chamber and a compensation chamber;
- (e) said collector chamber enclosing said tube ends adjacent to said collector plate;
- (f) said compensation chamber being adjacent to said expansion tank;
- (g) means for holding said water box in place between said expansion tank and said collector plate when said expansion tank and collector plate are sealingly connected;
- and
- (h) said means for holding including ribs cooperating with said water box.
In a heat exchanger including a collector plate having a plurality of openings therein and a plurality of substantially parallel heat exchanging tubes each of which has an end mounted through a respective one of said openings, the combination of an expansion tank having opposite longitudinal side walls with respective edges connected to said collector plate on either side of said tube ends and a water box housed inside said expansion tank for separating the space between said expansion tank and said collector plate into a collector chamber on said collector plate side and a compensation chamber on said expansion tank side, said expansing tank having at least one rib depending therefrom engaging an intermediate section of said water box longitudinally thereof to hold said water box in place between said expansion tank and said collector plate.
