Abstract
Abstract A heat exchanger is disclosed which comprises first and second cores aligned substantially parallel to each other in a horizontal arrangement. Each of the first and second cores includes a plurality of substantially parallel, spaced-apart, flat tubes disposed in a vertical arrangement. A plurality of corrugated fins are located in and extend through the spaces. First and second header pipes are connected to either end of the flat tubes of the first core to permit fluid flow. Third and fourth header pipes are connected to either end of the flat tubes of the second core to permit fluid flow. First and second plates are disposed on both upper and lower ends of said first and second cores to securedly affix them. Therefore, since the first and second cores for use as a condenser and a radiator can be manufactured with the same production process, the cost of manufacturing the heat exchanger is reduced. Further, since the heat exchanger has a condenser and a radiator, it can be easily attached in an automobile engine.
