Abstract
The utility model belongs to the electric heating technology field, in particular to an oil tank heater of diesel automobile which is used to heat up the pure-point diesel in the oil pipe in winters. The utility model is characterized in that the other end of a heat conductivity circuit pipe is provided with flanges which are hermetically engaged with an oil nut and a sealing insulation pad, a plurality of radiation holes are arranged on the heat conductivity circuit pipe which is connected with a electric-heat wire and relative position of pipe walls of an insulation pipe. The utility model has the advantages of simple structure, favorable radiation effect, long service life of the electric-heat wire and safety and reliability.
Description
Technical field:
The utility model belongs to the electric-heating technology field, is specifically related to that a kind of to be used for winter temperature on the low side to coagulating the diesel oil motor vehicle oil box heater of thick diesel oil heat temperature raising in the fuel tank.
Background technique:
The electric heating apparatus that the Motor Vehicle diesel fuel tanks uses in the prior art, form by the interior outer suit heat conduction loop pipe of porcelain tube of establishing electric heating wire, there is not radiation hole on the tube wall of heat conduction loop, its shortcoming is: sealing is poor between oil transportation nut and the heat conduction loop pipe, and electric heating wire is when overheated, easily burn, working life is short.
Summary of the invention:
The purpose of this utility model provides a kind of simple in structure, good heat dissipation effect, porcelain tube long service life, safe and reliable diesel oil motor vehicle oil box heater.
The technical solution of the utility model is: a kind of diesel oil motor vehicle oil box heater, be positioned at insulation tube inner chamber, the outer suit heat conduction loop pipe of insulation tube by electric heating wire one side, and electric heating wire one end links to each other with heat conduction loop pipe one end; The opposite side of electric heating wire is established the insulation sheath, and this end is connected with wiring terminal one end of tape insulation sheath; The wiring terminal the other end is stretched out by the through hole on the sealed insulation pad on oil transportation nut one side; The sealed insulation pad is connected on oil transportation nut one end by hold-doun nut; The other end that it is characterized in that the heat conduction loop pipe is established flange and is cooperated with oil transportation nut, sealed insulation pad conical surface seal; On the heat conduction loop pipe of the end that links to each other with electric heating wire and the corresponding position of insulation tube tube wall, be provided with a plurality of radiation holes.
Owing to adopt technique scheme, the heat conduction loop pipe the other end establishes that conical surface seal cooperates between flange and oil transportation nut and the sealed insulation pad, good sealing effect, the cylindrical of heat conduction loop pipe is provided with a plurality of radiation holes, the unlikely overheated electric heating wire that causes burns, thus have simple in structure, good heat dissipation effect, oil-proof, electric heating wire long service life, safe and reliable advantage.
Description of drawings:
Come the technical solution of the utility model is described in further details below in conjunction with the drawings and specific embodiments.
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
With reference to the accompanying drawings.A kind of diesel oil motor vehicle oil box heater is positioned at insulation tube 8 inner chambers, insulation tube 8 outer suit heat conduction loop pipe 7 by electric heating wire 5 one sides, and electric heating wire 5 one ends link to each other with heat conduction loop pipe 7 one ends; The opposite side of electric heating wire 5 is established insulation sheath 6, and this end is connected with wiring terminal 4 one ends of tape insulation sheath; The wiring terminal the other end is stretched out by the through hole on the sealed insulation pad 3 on oil transportation nut 1 one sides; Sealed insulation pad 3 is connected on oil transportation nut 1 one ends by hold-doun nut 2; The other end that it is characterized in that heat conduction loop pipe 7 is established flange 10 and is cooperated with oil transportation nut 1, sealed insulation pad 3 conical surface seals; On the heat conduction loop pipe 7 of the end that links to each other with electric heating wire 5 and the corresponding position of insulation tube 8 tube walls, be provided with a plurality of radiation holes 9.
