Abstract

Heat exchanger with two into each other running spiral channels (12, 14) for the flow of a heat yielding and of a heat absorbing medium, with two plates (10, 10') closing frontally the channels (12, 14) as well as with an inlet aperture (32) and with an outlet aperture (34) for each of the two channels (12, 14), whereat for the construction of a compact and easily dismantable unit and for a sure seal of the channels (12, 14) the spiral wall surfaces limiting the channels (12, 14) radially to the outside and to the inside have a straight generatrix and whereat the axial ends of the channel walls (16) are pressed against an elastically flesible seal side which is provided at the respectively opposing plate (10, 10').
