Description
Technical field
The utility model relates to a kind of EMU water tank air heating pipe, especially a kind of for the water in heating water tank, reach the heating tube of antifreeze object.
Background technology
In prior art, EMU water tank generally adopts the heating of companion hot line and electric blanket, mainly has following defect: (1) high energy consumption: cannot realize temp autocontrolledly, can only keep constant temperature; (2) install, dismantle inconvenient: need first pull down casing outsourcing and could safeguard, change; (3) along with the increase of service time, its efficiency of heating surface can be more and more lower.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of EMU water tank air heating pipe is provided, and the thermal efficiency is high, heating is even, and long service life.
The technical scheme providing according to the utility model, a kind of EMU water tank air heating pipe, comprises heating mounting pipe, feature is: at described heating mounting pipe inner chamber, metal tube is set, the two ends of metal tube are fixed by plug; Be uniformly distributed heating wire at described metal tube inner chamber, in the space between heating wire and metal tube, fill magnesia powder, one end of metal tube arranges binding post, and binding post stretches out the plug outside of one end.
At the outer surface of described metal tube, spiral helicine fin is set.
The utility model has the following advantages: (1) is simple in structure, and mechanical strength is high, long service life; (2) low energy consumption, operating temperature is self controllable; (3) little, high temperature resistant, corrosion-resistant, the thermochemical property good stability of quick heating, thermal inertia, dielectric strength are high; (4) pollution-free, be a kind of heater of clean type, meet the requirement of the high rhythm of modern production, high-quality; (5) design, manufacture, install all very convenient, economic security, safeguard and replacement cost low.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Detailed description of the invention
Below in conjunction with concrete accompanying drawing, the utility model is described in further detail.
As shown in Fig. 1～Fig. 2: as described in EMU water tank air heating pipe comprise binding post 1, plug 2, metal tube 3, heating wire 4, magnesia powder 5, fin 6, heating mounting pipe 7 etc.
As shown in Figure 1 and Figure 2, the utility model comprises heating mounting pipe 7, at heating mounting pipe 7 inner chambers, metal tube 3 is set, metal tube 3 adopts stainless steel seamless pipe, the two ends of metal tube 3 are fixed by plug 2, be uniformly distributed heating wire 4 at metal tube 3 inner chambers, in the space between heating wire 4 and metal tube 3, fill all good magnesia powders 5 of heat conductivility and insulating properties; One end of described metal managerial cadre arranges binding post 1, and binding post 1 stretches out the plug helmet outside of one end; At the outer surface of described metal tube 3, spiral helicine fin 6 is set.
EMU water tank air heat tubular construction advanced person described in the utility model, the thermal efficiency is high, heating is even, while having electric current to pass through in heating wire, the heat producing spreads to metal tube surface by magnesia powder, be delivered to again in heated object or air and go by the fin of metal surface, reach the object of heating.
