20150129173 | APPARATUS FOR EXHAUST HEAT RECOVERY WITH EMBEDDED VALVE ACTUATOR - An exhaust heat recovery apparatus may include a bypass valve that is rotatably provided on a bypass path through which a high-temperature exhaust gas passes to open or close the bypass path, a heat exchanger that is communicatively connected to the bypass path to allow heat exchange to be performed between the high-temperature exhaust gas supplied from the bypass path and a low-temperature coolant introduced through a coolant inlet when the bypass path is closed, a valve actuator including a rod moved up and down by expansion or contraction of a wax sealed therein, and a connection part that converts an up and down motion of the rod into a rotary motion to allow the bypass valve to open or close the bypass path along with movement of the rod. | 05-14-2015 |
20130160434 | THERMOELECTRIC GENERATOR OF VEHICLE - A thermoelectric generator of a vehicle converts thermal energy of exhaust gas of an engine into electric energy by using a thermoelectric phenomenon, and may include: a high-temperature part heated by exchange heat and a plurality of pairs of heat transfer plates mounted on an outer peripheral surface of an exhaust pipe at a predetermined interval; pairs of thermoelectric modules acquired by bonding a P-type semiconductor and an N-type semiconductor, interposed between the pairs of heat transfer plates to generate electricity, and electrically connected to each other; and a low-temperature part interposed between the pairs of thermoelectric modules and cooling inner surfaces of the pairs of thermoelectric modules. The plurality of thermoelectric modules generates electricity by a difference in temperature between heated outer surfaces and cooled inner surfaces. Thermoelectric efficiency is improved and a small-sized thermoelectric generator of a vehicle may be implemented. | 06-27-2013 |
20130081721 | EXHAUST-DOWNPIPE FOR VEHICLE - An exhaust-downpipe of a vehicle may include a base portion connected to a top of a catalyst converter having a vertical cylinder, an inlet circularly opened in a horizontal direction, an introduction round portion extending straight along the horizontal direction from the inlet and then and curvedly bent downward toward the base portion, and branch line portions connected to both outsides above the base portion with both ways branching and drawing a circular arc from the introduction round portion. | 04-04-2013 |
