Abstract:
1. A heat exchanger for a vehicle comprising: a first radiator for heat-exchanging high-temperature cooling water passing though an engine, into low-temperature cooling water and discharging the low-temperature cooling water toward the engine; a second radiator mounted integrally with the first radiator, the second radiator allowing high-temperature cooling water passing though an electronic component equipped inside the vehicle to pass therethrough, heat-exchanging the high-temperature cooling water into low-temperature cooling water, and discharging the low-temperature cooling water to the electronic component; and a reservoir tank bonded integrally to the second radiator via a communication pipe by means of brazing for allowing cooling water to be introduced from the second radiator to the reservoir tank though the communication pipe, the reservoir tank having a cooling water outlet located higher than an upper portion of the second radiator for allowing the introduced cooling water to flow toward the electronic component, a filler neck formed on the upper portion thereof for replenishing cooling water, and a drain part formed on the lower portion thereof for discharging cooling water.
