Problems solved by technology

The elastic element has some vibration-damping properties, but its effect is not sufficient
Also, specifically in longer heat exchangers, vibrations can only be effectively handled by known elastic elements located elsewhere

Abstract

The exchanger has a bundle of pipes (2) that is inserted into a housing (11), where exhaust gas flows via the pipes, and a coolant channel (5) is arranged between the pipes. The bundle of pipes has a lattice-like, metallic retaining device (10) that reinforces the bundle to the housing. The retaining device is formed as a single piece with resilient cantilevers (12a) that are deformed against an insertion direction, where an elastic force is directed against the housing. Elongation and deformation induced by alternating a thermal stress load are provided by an elastic device (20).

Description

technical field [0001] The present invention relates to heat exchangers such as exhaust heat exchangers. Background technique [0002] EP 1348924 A2 and EP 1544564 A1 disclose an exhaust heat exchanger. These heat exchangers have basically achieved their intended function. However, in recent years, the exhaust gas mass flow rate and the exhaust gas temperature of motor vehicle engines have increased, resulting in increased thermal stress on the exhaust gas cooler. These changes can lead to fractures and similar failures caused by excessive temperature changes in stress and can lead to system failure. [0003] Improvements to exhaust heat exchangers have been considered with a view to their ability to withstand the stress of temperature changes. A solution is known, for example, from WO 03 / 036214 A1. In this document, grooves and bellows are provided in the main body, whereby the expansion behavior of the individual components of the exhaust gas heat exchanger can be reli...
