Abstract: The present invention relates to a heat recovery system comprising a device which allows the connection between the elements of said system, such as a heat exchanger and an actuator controlling a valve of the present system. Said actuator is in turn configured such that its operation depends on the behavior of a substance due to the action of the temperature of a fluid, for example the liquid coolant used in the heat exchanger of the system, which is arranged in an exhaust duct of an internal combustion engine. Additionally, the invention also relates to a method of assembly of a system having these features.

Abstract: The present invention relates to a heat recovery system for internal combustion engines which is arranged in an exhaust gas conduit. The system allows transferring heat from the exhaust gas conduit to a liquid coolant through a heat exchanger and includes a flow guide element to prevent undesired recirculation, allowing subsequent energy optimization of the heat recovery device.
