description Compact aluminum heat exchanger manufactured from welded flat tubes with internal and/or external fins for cooling of power electronic devices and/or battery cells. The fin insert is prefabricated and inserted into the flat tubes for facilitating of flow turbulence and thus heat dissipation and have fins with undulating or wavelike shape manufactured by sampling or corrugating. Flat tubes are bent and welded along their length on their smaller side facilitating mechanical strength of the tubes. Tubes are manufactured from a core alloy containing 0.3 to 1.8 wt % Mn, 0.25-1.2 wt % Cu, 0.02 wt % Mg, 0.01 wt % Si, 0.05 wt % Fe, 0.2 wt % Cr, balance aluminum and unavoidable impurities up to 0.05 wt %. Fin inserts are manufactured from aluminum alloy comprising Mn 0-3 wt %, Fe 0-1.5 wt %, Cu 0-1.5 wt %, Mg 0-1.5 wt %, Si 0-1.0 wt %, Zn 0-4 wt %, Ni 0-1 wt % and Zr, Ti, Cr V 0-0.3 wt % each.
