Description
Technical field
Electrothermal tube is the utility model is related to, relates generally to electric boiler, central heater, air source hot pump water heater, the sun
The hot-water heating systems such as energy water heater, central air-conditioning electric heating device, electric heater, electric wall-hung boiler, water dispenser, boiler, leaching
Steep the electrothermal tube in water tank.
Background technology
The electrothermal tube being currently used in hot-water heating system water tank, 100% is by China Technology Standard GB/T23150-2008
《Water heater tubular heater》It is " to make heater by shell, heating alloy of metal tube, at one end or two ends have extraction
Rod, closely knit magnesium oxide powder dielectric is loaded in metal tube, to fix the element of heater；" this metal shell electricity
Thermal element, it is completely sunk in the water, after long-time use, meeting scaling, reduces heating efficiency, and corrosion breakdown, make water band
Electricity, it is world-famous puzzle.
The Shunde Guang Sheng electrical equipment limited company application number 201510579205.4 on the 5th of September in 2015,
201510579286.8th, 24 patent applications such as 201510579371.4,201510579374.8 and 201510579451.X carry
Be supplied with electric power heat pipe mounting structure, does not have the structure for describing electrothermal tube in above-mentioned patent application；Present patent application supplements electrothermal tube
New structure, it is main to supplement blind hole pipe, and the structure of electrothermal tube is described.
Utility model content
The purpose of this utility model is for electric boiler, central heater, air source hot pump water heater, solar water
A kind of electrothermal tube used in device, central air-conditioning auxiliary heater and electric heater, water dispenser, boiler etc., there is provided new knot
Structure scheme.
Technical measures of the present utility model are that electrothermal tube 3 is combined and formed by shell 3-4, the parts of electrical heating elements 3-2 bis-：Outside
Hollow tubular is made by metal or nonmetallic materials in shell 3-4, and one end sealing, the other end opens wide, be formed with unlimited one end screw thread or
Flange is engaged with the screw thread on water tank or flange-interface, in the air 3-5 in shell 3-4, installs electrical heating elements 3-2,
The two is combining structure, and electrical heating elements can take out from shell；Heated when electrical heating elements work for water proof, and can be in water tank
In load and take out when having water.
The outer tube of the electrical heating elements 3-2 is nonmetallic blind hole pipe or straight pipe or bends to the pipe 3-1 of U-shaped, built-in
Have heating wire 3-7, eduction rod or wire 3-3 ends will seal, taken out in pipe low vacuum or non-combustible, the not combustion-supporting gas of injection or
Inert gas loads non-closely knit magnesium oxide powder or air 3-8；Or electric heating element 3-2 halide torches or carbon fiber electric heating
Pipe makes；For single-ended extraction, eduction rod or wire 3-3 are in same one end.
The electrical heating elements 3-2, can also be by following structure fabrication：The heating wire 3-7 of spring shape will be coiled into, be wound on and be formed with
On the ceramic mandrel 3-6 of helicla flute, wherein one end is drawn by the way that the hole in the middle part of electrical heating elements 3-2 ceramics mandrels is made, and makes two
Individual terminal is in same one end；Or by heating wire 3-7 in the metal tube, with closely knit magnesium oxide powder by heating wire 3-7 and metal
Pipe isolated insulation, is again bent at shape, makes eduction rod in same one end.
Above-mentioned electrical heating elements 3-2 is in shell 3-4, just as the electrothermal tube of Large Copacity water tank；During energization work,
Electrical heating elements 3-2 dry combustion methods in atmosphere.
The beneficial effects of the utility model are that electrothermal tube surface loading is low, long lifespan；Electrothermal tube heats for water proof, can reach
II electric appliances highest ranking safety standard；Water tank need not discharge water when electric heating element is changed simultaneously, can arbitrarily change.
