Sometimes, the drying and sterilizing channel itself does not need to be heated because there is no need to sterilize the articles, but needs to provide hot water for the personnel sterilizing channel, or provides heat for the vehicle drying room, in this patent, a rotatable tile-shaped structure of the drying and sterilizing heat conduction plate 220 is adopted to avoid waste of resources, a plurality of heat conduction grooves 22021 are distributed along the circumferential direction on the circumferential inner surface 2202 of each of the plurality of tile-shaped structures, the heat conduction grooves 22021 are external narrow notches and internally form a step-shaped wider groove body, therefore, the circumferential inner surface 2202 can rapidly absorb heat radiation energy, and the circumferential outer surface 203 of each of the plurality of tile-shaped structures is a reflective chrome-plated surface because infrared radiation energy has emission characteristics, and 90% of the radiation energy can be reflected back for the mirror surface, therefore, the smooth mirror surface circumferential outer surface 2203 of each of the plurality of tile-shaped structures, can reflect away the radiation heat energy that infrared ray heat radiation unit 210 gived off, can avoid like this to drying the meaningless heating of disinfection passageway, through smooth mirror surface circumference surface 2203 of each in a plurality of tile structures, can also reflect the radiation energy to hot water heat conduction passageway 230, can provide the heat for hot water heat conduction passageway 230 more fast like this.

Particularly, in the embodiment of the present invention, the rotation shaft 2201 is driven by the driving mechanism to move toward or away from the central axis of the infrared heat radiation unit 210, thereby separating or gathering the plurality of tile-shaped structures of the heat conduction plate for drying and sterilizing.

Each of the plurality of tile-shaped structures has a cross section of a partial circular arc shape, and when the rotation occurs, the edges thereof cannot be combined, so in the present embodiment, a manner is adopted in which the rotation shaft 2201 is driven by the driving mechanism to move toward or away from the central axis of the infrared heat radiation unit 210, thereby separating or gathering the plurality of tile-shaped structures of the drying and sterilizing heat conduction plate 220. When the smooth mirror circumferential outer surface 2203 of each of the plurality of tile-shaped structures is aligned with the infrared heat radiation unit, the plurality of tile-shaped structures are drawn close to the infrared heat radiation unit 210, so that a gap between the plurality of tile-shaped structures can be avoided, radiation energy is prevented from being dissipated to the air, and energy can be saved.
