Abstract
The invention concerns a heat exchanger, in particular for a motor vehicle, comprising an array of tubes and fins, whereof the ends of the tubes are inserted in holes of a collector plate. The latter is generally planar and an inserting plate is arranged, directly mounted on the collector plate and provided with openings for allowing through the ends of the tubes and delimited by a peripheral edge forming a lateral stop for a rim of a manifold maintained by crimping means.
Claims17
A heat exchanger comprising:
- a bundle of tubes and fins,
- a manifold plate, the tubes having ends that are introduced into holes of the manifold plate,
- a sealing gasket,
- a manifold box having an open face delimited by a peripheral rim, the manifold plate provided with crimping means that bears against the peripheral rim of the manifold box while compressing the sealing gasket, the manifold plate generally planar, and
- an insertion plate mounted on a side of the manifold plate next to the manifold box, the insertion plate having openings for the ends of the tubes to pass through, the openings of the insertion plate arranged in front of the ends of the tubes, each opening having an edge which is widened in the direction of the manifold box to favor admission of a fluid into the tubes, the insertion plate delimited by a peripheral edge forming a lateral stop without a groove for the peripheral rim of the manifold box.
