Exhaust gas system with circulation heat pipe

摘要

An exhaust gas system includes an exhaust gas pipe with an integrated evaporator. In order to make the evaporator independent of the site of installation and the mounting position, a capillary structure is arranged between the outer sleeve pipe and the exhaust gas pipe. For increasing the efficiency of the evaporator, vapor grooves are provided in an area of an outer sheath surface of the exhaust gas pipe and fluid grooves are provided in an area of an inner mantle surface of the sleeve pipe.

1. An exhaust gas system for an internal combustion engine, comprising:
an evaporator comprising an exhaust gas pipe, a sleeve pipe and a capillary structure, said capillary structure formed as a porous body between the sleeve pipe and the exhaust gas pipe and comprising vapor groover provided in the capillary structure in an area of outer sheath surface of the exhaust gas pipe and fluid grooves provided in the capillary structure in an area of an inner sheath surface of the sleeve pipe; wherein an operating medium for transporting heat which was withdrawn from exhaust gas in a form of heat energy transitions from a liquid state to a gaseous state when traversing the capillary structure; and a condenser connected to the evaporator via conduits.
