Abstract:
1. A method for manufacturing a series of heat exchangers for mounting in a series of motor vehicles having a lower support and an upper transverse support for the heat exchanger, wherein the series of motor vehicles includes more than one different support configuration for the heat exchanger, wherein the heat exchangers include at least one injection molded collecting tank, upper and lower supporting elements and a block of tubes connected to the collecting tank, the method comprising: injection molding said collecting tank for the series of heat exchangers, employing an injection molding die having a single design, whereby each collecting tank of said series of heat exchangers is of uniform tank size and heat exchanger design, wherein prior to said injection molding step, one of a plurality of different inserts is placed in said die to selectively form on said tank, for one of said support configurations, either the upper and/or the lower supporting elements; and assembling the collecting tank with an identical tube block for the entire series of heat exchangers.
