Title:
EGR GAS POWER GENERATOR
Document Type and Number:
WIPO Patent Application WO/2007/026432
Kind Code:
A1
Abstract:
An EGR power generator has heat transmission channels for EGR gas and cooling water, where the channels are stacked on each other and are each formed in a shape having a closed cross section. In the EGR power generator, an EGR gas channel is connected to a tube plate, a cooling water channel is connected to a circular tube-shaped inlet/outlet section, and a thermoelectric conversion module is provided between the channels. An electric current flowing in a thermoelectric element is made controllable, and a regeneratable filter is placed on the upstream side of the EGR gas. By this construction, electric power is obtained from cooling and exhaust heat of the EGR gas at the same time, and heat radiation load of a radiator is reduced. Also, the EGR gas power generator is reduced in size so as to be placeable in an engine room with cooling ability necessary as an EGR cooler maintained.
