<p>It comprises at least two profiles (1, 1'), preferably of aluminium, provided with parallel heat dissipating fins (2, 2', 2"), which are assembled to each other by means of engagement (3). The profiles (1, 1') have at least one housing (5) defined between the heat dissipating fins (2, 2', 2") for insertion of at least one electric heating plate (4, 4'). The heating plates (4, 4') comprise means of heating mounted inside an external enclosure (11, 11') which consists of an elastically compressible closed symmetrical profile of slightly greater width than the width of the housing (5) for the press-fitting thereof in said housing (5).</p> |
