There are provided an automobile
heat exchanger having a header formed integrally with a tank and a method of manufacturing the same, and, more particularly, an automobile
heat exchanger comprising a top header
pipe unit formed of a pair of header pipes and a bottom header
pipe unit formed of a pair of header pipes, the top header
pipe unit to be connected to top ends of tubes and the bottom header pipe unit to be connected to bottom ends thereof, and the header pipe including a header formed integrally with a tank. In the
heat exchanger, each header pipe is manufactured in a welded type or folded type so that the header is formed integrally with the tank. Accordingly, unlike a conventional heat exchanger, the present invention does not require any separate
metal mold or assembling means for assembling the header and tank. Consequently, the manufacturing cost is reduced and the manufacturing time is shortened by simplifying the processes. Furthermore, the pressure strength in the header-tank increases and the risk of leaking a heat exchanging medium decreases, to increase the efficiency of heat exchange. Further, the width wise sectional shapes of the top and bottom header pipe units are controlled so that the condensate generated on the surface of a plurality of the header pipes is easily discharged.
