The present invention relates to a heat exchanger, in particular for cooling of exhaust gases according to the restrictive part of paragraph 1 of the claims.

During combustion of fuel in internal combustion engines exhaust gases are formed. Part of the exhaust gas is cooled in heat exchangers, particularly in heat exchangers for exhaust gases, and then routed to the charge air to the internal combustion engine.

There are various designs of welded and brazed heat exchangers, in particular heat exchangers for exhaust gases in the form of systems of bundles of tubes or systems of the stacks of plates. Known heat exchangers are, in particular, thin-walled housing. They require additional fixing elements for mounting on the engine or by the transport device. Along with additional cost is associated with higher need for placement. When you pass flow heat exchangers, in particular heat exchangers for exhaust pipes of the heat exchanger, feel the heat of the longitudinal extension and transverse thermal expansion. For this reason, in most cases, the body is made of elastic. The connections for the coolant, which provide inlet and outlet of the cooling means, in connection with the elasticity of the elastic body is attached to the motor b is the eye of the internal combustion engine, accordingly to the water system of the engine.

From DE 10218521 A1 is known a heat exchanger for exhaust gases, in particular for vehicles with exhaust gas recirculation, which consists of a casing for the cooling means and the beam pipe through which the exhaust gases and which is washed by the cooling means, which is placed above the tube sheet and tube bundle, the tube lattice form a closed force flow, and the power flow is the saddle under the flap. The ends of the pipes are fixed in tube grid, which on its part is welded with the housing. The housing has a saddle under the flap. The outer ring connects to overlap the inner ring and forms a sliding fit. Moving landing with two O-rings sealed from the outside, i.e. relative to the atmosphere, so that the coolant could not get out.

From DE 10204107 A1 is known a heat exchanger, in particular a heat exchanger for exhaust gases of vehicles with the beam pipe, which passes through the gaseous medium and which is washed by the liquid cooling medium, whose tubes with their ends placed in the tube sheet holes and rigidly connected with the housing, surrounding the beam pipe, which end side connected to the tube plate and which passes cooling the tool, and tubular grille and the housing is made of heat-resistant and corrosion-resistant alloy, and the housing has at least one set around a compensatory bumps. This corrugation gives the housing a sufficient elasticity in the longitudinal direction of the pipe, so that the body housing due to elastic elongation can follow more severe elongation of the pipe carrying the exhaust gases, without being subjected unacceptable deformation or without exerting a negative influence on the welded joint between the pipes and bars and bars and body.

Further, from DE 10224263 A1 is known a heat exchanger for exhaust gases, in particular for vehicles with exhaust gas recirculation, consisting of a casing with a casing for the cooling means and the beam pipe through which the exhaust gases and which is washed by the cooling means, and which is placed over the first and second tubular bars in the housing, the first tubular bars rigidly connected to the housing and thus forms a fixed support for the tube bundle, and the second tubular grating is formed in the form of an elastic plate of synthetic material. The bottom due to its modulus of elasticity may be due to elastic deformation to perceive a certain elongation, which occurs in the beam pipe when the heat is of mennica for exhaust gases. This leads to the elastic bending or deformation of the bottom of a synthetic material that helps prevent unacceptable stresses in the parts of the structure.
