Reflective device unit and concatenation formula heating device and heating device system thereof

The utility model discloses a reflective device unit for a n cavity close structure that the reflector unit splices, is provided with the plane of reflection on every reflector unit, n is individual the plane of reflection encloses and synthesizes hollow heating chamber, n >= 2. A concatenation formula heating device and system are still disclosed, including infrared heater and a plurality of before if reflective device unit, a plurality of reflective device units are concentric shaft and set up, the synthetic zone of heating is enclosed jointly in each heating chambeies of a plurality of reflective device units, infrared heater sets up in the zone of heating. The utility model discloses it just so can change the heatable region as required at the form that can assemble to set up the furnace body as to between can adjusting the furnace body zone of heating according to the size of heating object, solved because of the heating object too bigly, it is improper that shapes such as heatingfurnace body or heating
