Description

Efficient air heating device

Technical field

A kind of warmer is the utility model is related to, more particularly to a kind of design and manufacturing technology field of heat conduction oil warmer.

Background technology

Existing warmer, the warmer as shown in patent 201620369200.9, it include base, heating tube, Heat radiator body, outer cover, heat radiator body include central cylinder, radiating fin, and radiating fin is distributed on central cylinder lateral wall, dissipate The lower end of the central cylinder of hot body is bolted on base；The middle of the base set installation through-hole, central cylinder it is interior Hole is corresponding with installation through-hole, and central cylinder is provided with bottom surface, the bottom surface of central cylinder be threaded hole heating tube through installation through-hole, Screwed hole is fixed on base, on central through hole bottom surface, to be tightly connected between heating tube and the central cylinder bottom surface；At center The upper end of cylinder is tightly connected end cap, and end cap is fixed by screws in central cylinder upper end；Outer cover is covered on outside the radiating, outer cover Lower end coordinate on base, outer cover is fixed by screws on end cap.This warmer radiating is passed with radiation mode in air Broadcast, outside certain limit, heating effect is bad；Tie point is more, structure slightly complicated, and processing assembling is not easy.

Utility model content

The defects of in order to overcome existing warmer, the utility model provide a kind of efficient air heating device.

The utility model includes outer tube body, interior tube body, upper plate, lower shoe, electric heating tube, overhead guard, base, said inner tube Body is co-axially located in the outer tube body, and four connecting ribs, the upper plate, lower shoe are set between the inside and outside body Be sealedly connected on the both ends of the inside and outside body respectively, the centrally disposed through hole of the upper plate, lower shoe, the upper plate, under Central passage of the through hole of bottom plate respectively with said inner tube body connects；The electric heating tube is arranged between the inside and outside body, The bottom sealing of the electric heating tube is fixed on the lower shoe；Conduction oil is filled between the inside and outside body；Described Some uniform radiating fins are set on the lateral wall of outer tube body；The lower surface of the lower shoe is fixedly connected with the base, institute The top connection cover for stating upper plate puts the overhead guard, and the base is trumpet type, is set in the side wall of the base some uniform Air vent, base center set through hole, penetrated between the through hole and lower shoe central through hole of the base center；The overhead guard For blower cover or unpowered blast cap, the overhead guard is a lid, and small half of opening is set on the lid.

During utility model works, electric heating tube is heated to conduction oil, and a part of heat is radiated by radiating fin Go out, a part of heat flows out by interior tube body central passage, because the small half of entirety of overhead guard prunes to form opening, forms air inducing Cover uses unpowered blast cap, in the state of cold, hot pressure, forms air-flow, the heated air in interior tube body center, outflow, so that Reach the faster purpose of radiating, hot blast blowout, its thermal radiation range is bigger, and heating effect is more preferable.This warmer structure is also simple, Rationally, it is convenient to manufacture.

Twice annular groove corresponding with inside and outside body is set respectively on upper plate described in the utility model, lower shoe, it is described The both ends of inside and outside body are respectively placed in the annular groove of the upper plate, lower shoe.So set its sealing effectiveness more preferable, keep away Exempt from conduction oil leakage.

The utility model uniform four connection rib set along tube length direction on the lateral wall of the outer tube body, The both ends of each connection rib set screw respectively, and upper plate, lower shoe are fixedly connected by bolt with being connected rib respectively.Pass through Rib connecting components are connected, stable connection is rational in infrastructure.

Some screws are set on lower shoe edge described in the utility model, and the base passes through bolt and the lower shoe Screw connects.

Overhead guard described in the utility model is fixedly connected by bolt with the connection rib on the outer tube body.

Overhead guard described in the utility model is hemisphere lid, and small half of set of the hemisphere lid is open, be open towards side Side.Hemispheroidal cover, wind resistance is small, and air-out is fast, will not upset air-flow.

Conduction oil between inside and outside body described in the utility model account at least half appearance of cavity between inside and outside body Product.After the heating, conduction oil expands, and the conduction oil of a half volume, its interior pressure is small, prevents from rupturing caused by pressure is excessive, protects Safety is demonstrate,proved.

The inside and outside body of the utility model, four connecting ribs, four connection ribs, some fins are integrally set by manufacture Put.Overall manufacture, it is easy to process, tie point is reduced, product is more firm, is hardly damaged, service life length.

Electric heating tube described in the utility model is two, and sealing is set between each electric heating tube and lower shoe outer face Packing ring.Seal washer ensure that sealing effectiveness, avoid oil leak.

When the utility model sets high-power, blower fan is set in the base, and the air outlet of the blower fan is described in The passage at interior tube body center.When the face of heating is larger, using high-power heating, it with fan, so can faster radiate, reach big The purpose of scope heating.
