An annular seal for a motor vehicle heat exchanger is configured to be stretched between two opposite supports that the annular seal surrounds. The annular seal includes two opposite support parts that cooperate with the two supports, two connecting parts joining the support parts together, and an annular bead that deforms elastically by axial compression perpendicular to a plane parallel to the annular shape of the seal. Additionally, said annular bead is extending in the support and connecting parts. Further, the cross section of the annular bead between each support part and the connecting parts to which the annular bead is joined changes such that a radial dimension of the annular bead, measured in a median plane of the seal parallel to the annular shape of the seal, is smaller in the support part than in the connecting parts.

A heat exchanger includes a header and a side plate. The header has a face plate that defines a plurality of orifices. The header has a protrusion that extends outward from the header and down such that a gap is formed between the header and the protrusion. An external portion of the protrusion is configured to break away from the header during thermal expansion. The side plate is disposed adjacent to an array of alternating tubes and fins. Each tube extends into one of the orifices of the plurality of orifices. The side plate has an end that is secured to the external portion of the protrusion.

A cooker with a gasket may include a top plate on which a plurality of burners may be placed; a manifold panel provided in front of the top plate and including thereon a plurality of knobs to control output powers of the plurality of burners; and a gasket that extends along a front end of the top plate and is compressed between the top plate and the manifold panel to hermetically seal the top plate and the manifold panel.
