A heat exchanger is used for an air conditioner installed in a vehicle such as an electric car and is basically designed as a laminated type, which is constructed by assembling a pair of heat-exchanger units (A, B) together. Herein, each of the heat-exchanger units is constructed by a pair of headers (10, 11), which are arranged in parallel with each other in a vertical direction and between which tubes (12) and cooling fins (13) are alternately arranged along a horizontal direction. Herein, each of the tubes and each of the cooling fins are extended in the vertical direction between the headers. Partition plates (16) are arranged inside of the headers at selected positions such that an overall front area in which the tubes and cooling fins are alternately arranged between the headers is divided into a number of parts (PA, PB), among which refrigerant sequentially flow from one part to another in a reciprocating manner. Herein, all the parts can be equally divided to have a same sectional area, or they are gradually changed (i.e., reduced or enlarged) in sectional area along a refrigerant flow direction corresponding to the horizontal direction. It is possible to change an overall front shape of the heat exchanger, which is originally a rectangular shape, to a prescribed shape such as an L-shape using an intermediate header (17), by which the heat exchanger is arranged not to interfere with some device or equipment inside of the vehicle.
