Described shell body includes body, and the upper side wall of body is provided with air inlet, and the lower wall of body is provided with gas outlet, and the bottom of body is provided with thermometer hole。
On described half-moon-shaped deflector, processing has cross fixing hole, and surrounding's processing of cross fixing hole has circular tap hole。
Described half-moon-shaped deflector has four pieces, four pieces of half-moon-shaped deflector interlaced arrangement。
This utility model has the advantages that:
1, described a kind of nested type air heater, graphite collet is embedded in portion at shell body, take full advantage of graphite material and be uniformly almost exhausted thermal property in Z-direction in X/Y plane direction heat transfer efficiency height, heat transfer, effectively solve common air heater only with common rustless steel as shell structure time the deficiency that effect of heat insulation is poor, power consumption is big, in addition, graphite collet also has very strong thermostability, therefore, in use and gap will not occur between shell body because of being heated。
2, described a kind of nested type air heater, on graphite collet, preparation has four annular grooves, in order to install semilune deflector, easy for installation firm, semilune deflector has cross fixing hole and circular tap hole, wherein cross fixing hole is consistent with the heating resistor shape on resistance heater, and circular tap hole is then to improve the flowing velocity of air-flow and ensureing that air-flow is fully heated；The mounting means of 4 semilune deflectors is the method laid that staggers, and namely adjacent its opening direction of half-moon-shaped deflector is contrary。
3, described a kind of nested type air heater, relatively simple for structure, working service is more convenient, power dissipation ratio is relatively low, enhances the experience of user。
