Dry type module for electricity floor heating

The utility model relates to a dry type module for electricity floor heating. The dry type module is composed of a heat preservation base plate (1), a large heat dissipation piece (2) and circular-arc-shaped heat dissipation pieces (3). The heat preservation base plate (1) is in a groove shape, wherein the groove width ranges from 6.5 mm to 7.3 mm, and the groove depth ranges from 7.5 mm to 8.5 mm. The large heat dissipation piece (2) is in a protruding shape and is fixed to the heat preservation base plate (1) according to groove lines of the heat preservation base plate (1). The periphery of the heat preservation base plate (1) is provided with the circular-arc-shaped heat dissipation pieces (3). The dry type module has the advantages that the heat generated by a heating cable can be quickly transferred to the surface of metal, quick temperature rising is achieved, and the heat transfer speed is higher than that of traditional concrete.
