HEAT EXCHANGER FOR VEHICLE
First Claim
1. A heat exchanger for a vehicle, comprising:
- a bypass pipe disposed at an exhaust gas line and formed with a bypass flow passage through which exhaust gas passes;
a heat exchange generator including an exhaust gas heat recovery component formed with an exhaust gas flow passage through which the exhaust gas flowed into from the bypass pipe passes and a cooling flow passage through which coolant passes to heat-exchange the exhaust gas and the coolant, and a thermoelectric generation component in which heat of the exhaust gas and the coolant are transmitted to a thermoelectric module, respectively, to produce electricity; and
a flow passage control component configured to control the exhaust gas flowed into the bypass pipe to selectively pass along the bypass flow passage or the exhaust gas flow passage, and to control the exhaust gas flowed into the exhaust gas flow passage to pass separately toward the exhaust gas heat recovery component or thermoelectric generation component.

Abstract
A heat exchanger for a vehicle is provided to improve fuel efficiency by implementing an integrated structure of exhaust gas heat recovery function and thermoelectric generation function. The heat exchanger allows exhaust gas that is flowed into the heat exchange generator in the cold start mode of the vehicle to pass through the exhaust gas heat recovery component side and thermoelectric generation component side. Therefore, the temperature of the coolant rapidly increases, thereby reducing the engine warm-up time, and electricity is generated through thermoelectric module, thereby maximizing the fuel efficiency improvement.
