Abstract
The utility model relates to a heating core of hair drier. No less than one strip of spacing block is arrayed in equal distance along the axis direction on the surface of the midheaven tubular insulating bracket which is fixed inside the insulating shell of the heater; and no less than two strips of isolating bracket are arrayed in equal distance and parallel with each other along the radial direction. A heater is fixed between each two axis direction isolating brackets. The utility model has the advantages that more heating wires can be contained by the insulating bracket in the condition of same size, increasing heat-exchange surface, improving thermal efficiency, prolonging service life, and reducing wind noise.
Description
Technical field
The utility model relates to electric heating air duct heater, particularly electric heating air duct heat generating core.
Background technology
The heat generating core of existing electric heating air duct is traditional wound form heat generating core, is about to heating wire and laterally is entwined on pottery or mica support.Its weak point is that the contact-making surface of air and heating wire is limited, and the heat efficiency is not high, and useful life is not long, and the heating wire support has resistance to moving air, and wind is made an uproar bigger.
Summary of the invention
The purpose of this utility model provides a kind of electric heating air duct heat generating core, and this heat generating core can hold more heating wire on the insulating support under the condition of same size, increase heat exchange area, improve the heat efficiency and useful life, reduce the resistance of insulating support simultaneously, reduce wind and make an uproar moving air.
Technical solution of the present utility model is on the outer surface of insulating support of hollow tubular of insulation crust internal fixation of electric heating air duct heat generating core, equidistant vertically being arranged with is no less than one spacing block, radially equidistant and parallel to each other being arranged with is no less than two spacing block, is fixed with heating wire at per two axial isolation interblocks.
Be mutual series connection between the above-described heating wire, or be connected in parallel mutually.
Be axially arranged with along it in the body wall of the insulating support of electric heating air duct heat generating core of the present utility model and be no less than two through hole, be fixed with connecting line in through hole, connecting line links to each other with heating wire.
The input of above-described heating wire, output lead all are fixed on the air inlet end of electric heating air duct heat generating core.
The utility model has the advantages that and under the condition of same size, can hold more heating wire on the insulating support, thereby increased heat exchange area, improve the heat efficiency, increased the surface heat load, improve useful life, insulating support reduces the resistance of moving air simultaneously, has reduced wind and has made an uproar.
Description of drawings
Fig. 1 is an organigram of the present utility model;
Fig. 2 be among Fig. 1 A of the present utility model to organigram.
Embodiment
Shown in Fig. 1,2, the utility model comprises insulation crust 1, insulating support 2, heating wire 3, lead-in wire 4.The cylinder shell of insulation crust 1 for making with pottery, the hollow tubular body of insulating support 2 for making with pottery, on the outer surface of insulating support 2, along its axial equidistant 3 spacing blocks 5 that are arranged with, radially show 12 spacing blocks 5 along it, in the body wall of insulating support 2, a plurality of through holes 6 are axially arranged along it by the equidistant parallel of the big slightly size of the diameter of heating wire 3.End at insulating support 2 begins to embed heating wire 3 along its 5 of two axially adjacent spacing blocks, the other end at insulating support 2 turns back, again heating wire 3 is embedded between insulating support 2 another adjacent two spacing blocks 5, turn back again after arriving an end of insulating support 2, all embed on the insulating supports 2 vertically between all two adjacent spacing blocks 5 up to heating wire 3.The input of heating wire 3, the lead-in wire of output 4 all are fixed on the end towards electric heating air duct air inlet of insulating support 2.Through hole 6 on the body wall of insulating support 2 is used for placing the connecting line of heating wire 3, also can be used for placing lead-in wire 4, and lead-in wire 4 is connected with power input line, and connecting line can be used for the heating wire 3 of serial or parallel connection connection disconnection.After heating wire 3 is loaded onto insulating support 2, again insulating support 2 is contained in the insulation crust 1.
Claims (4)
1, electric heating air duct heat generating core, comprise insulation crust, lead-in wire, it is characterized in that on the outer surface of the insulating support of the hollow tubular of insulation crust internal fixation, equidistant vertically being arranged with is no less than one spacing block, radially equidistant parallel to each other being arranged with is no less than two spacing block, is fixed with heating wire at per two axial isolation interblocks.
