First when causing the user to use, water temperature can not in time rise because mode of heating is mainly that outer wall by heater provides temperature, and causes the user to complain waste with electric energy.

Second point makes heater can not play the effect of temperature prompt drop because mode of heating is mainly to lean on the outer wall of heater that heat is provided, thereby causes shorten the useful life of heater.Just accelerated the consumption of metals resources and the energy.

In said structure, in order to improve the electric heating vessel energy conversion efficiency, to reduce the wasting of resources.The spy is designed to heating-pipe structure to be convenient to change and installs, and need not consider waterproof quarantine measures complicated between electricity and water on producing, and has simplified production process, has improved production efficiency.Record 900 ℃ of the central temperatures of electrothermal tube through the laboratory, 220 ℃ of pipe table temperature.Because this change, heated liquid be by the center of electrothermal tube, absorption heat energy that will be faster and better plays the purpose of energy savings.

Summary of the invention

The purpose of this utility model is to provide a kind of mode of heating of the inside and outside heat-conducting structure different from traditional heating mode.The heating tube of equal-wattage, the electric heater of inside and outside heat conduction can be installed more convenient and quicker in production than conventional electric heater, and thermal energy conversion efficiency is faster and high.

The purpose of this utility model is achieved through the following technical solutions:

a kind of instantaneously heated type heater, by central tube 1, outer tube 2, insulating sleeve 3, heating wire 4, fairlead 5, porcelain bead or micelle 6, it is characterized in that: described central tube 1 is metal tube, heating wire 4 is enclosed within the periphery of central tube 1, heating wire 4 is the magnesium oxide bisque 7 of thermal conductivity and insulating properties with central tube 1 contact-making surface, outer tube 2 is enclosed within the periphery of heating wire 4, outer tube 2 is magnesium oxide bisques 7 of thermal conductivity and insulating properties with heating wire 4 contact-making surfaces, weld with fairlead 5 respectively at heating wire 4 two ends, use insulating sleeve 3 isolation between fairlead 5 and central tube 1, be plugged with porcelain bead or micelle 6 between fairlead 5 and outer tube 2.

As a kind of heating liquid for multiple fields or steam generator, described central tube 1 directly passes heating wire 4; Heating wire 4 passes outer tube 2; Between central tube 1, outer tube 2, heating wire 4 with insulating properties and thermal conductivity all excellent magnesia powder 7 fill and isolation; Heating wire 4 two ends are welded on respectively on fairlead 5, play the effect that connects power supply; Use sleeve pipe 3 insulation between fairlead 5 and central tube 1; Fairlead 5 is plugged with porcelain bead or micelle 6 with outer tube 2 two ends, prevents electric leakage; Central tube 1 two ends connect water inlet pipe and water outlet pipe, can fast heat the liquid of flowing through wherein or form steam.

The beneficial effects of the utility model:

This immediate heating type heater has multiple use: A heating to flow through the heated media such as water of central tube 1 in the use; The heated media such as water of central tube 1 are flow through in B heating, and control its flow and make it instantaneously producing steam; C is first by heated media such as outer tube 2 heating waters, the more heated media such as water that will heat form steam by central tube 1 Fast Heating.

Due to this immediate heating type heater, the inlet/outlet pipe of the heated mediums such as employing central tube 1 two ends connection water can be connected with various device, electrical equipment so easily.Purpose that in the use can fast simple installation electrothermal tube need not considered the quarantine measures of complexity between the heated mediums such as electricity and water on producing, simplified production process, has improved production efficiency.Record 900 ℃ of the central temperatures of electrothermal tube through the laboratory, 220 ℃ of pipe table temperature.Because this improvement, heated liquid etc. heated medium be by the center of electrothermal tube, absorption heat energy that will be faster and better plays the purpose of energy savings; And the temperature of electrothermal tube is in low-temperature condition always, can increase the service life.
