As described above in the description 'Background Art of the Invention', and as shown in FIG. 8 (a), tolerances are produced during manufacturing of each component, and tolerances are generated during assembling the manufactured components. Thus, when coupling a plurality of parts to the housing 110, a tolerance occurs between each part.

As shown in (b) of FIG. 8, the spacing between the components prevents heat generated from the heat generating film 15 from being conducted to the heat conductive metal plate 150 and the heat dissipation fin module 151. Thus, the heat generated from the heat generating film 15 is not easily conducted to the heat conduction metal plate 150 and the heat radiation fin module 151.

In addition, poor heat conduction between the heat generating film 15 and the heat dissipation fin module 151 also causes a problem that the air passing through the heat dissipation fin module 151 does not heat up smoothly.

As shown in (a) of FIG. 9, the contact block module 123 is inserted into the contact block accommodating groove 112 formed in the housing part 110, so that the contact block module 123 replaces the heat radiation fin module 151. In order to pressurize, the heat radiation fin module 151 is in close contact with the heat conductive metal plate 150 and the heat conductive metal plate 150 is in close contact with the heat generating film 15. Through this, heat generated from the heat generating film 15 may be smoothly conducted to the heat radiation fin module 151.

Smooth heat conduction between the heat generating film 15 and the heat dissipation fin module 151 may quickly heat the air passing through the heat dissipation fin module 151.
