Technical field
The utility model relates to a kind of electric heater, and specifically, the utility model relates to a kind of for the air heater in the passenger train carriage.
Background technology
Passenger train is the mobile place that the crowd is dense, and when moving cold season, for the environment temperature that has suitable passenger to have a rest in the compartment, equipped electric heater improves environment temperature usually.Although the existing supporting air heater brand difference of passenger train, all adopt electric heating tube as heater element, wherein patent publication No.: CN200710024837X " electric heater " is the most representative, the electric heating tube that states clearly in this technical scheme is smooth wall pipe, the manufacturing simple in structure, easy of light wall electric heating tube, steady quality.After the electric heating tube energising of this kind structure, the electric furnace heating wire that is on the axis directly is converted into heat with electric energy, and the heat that produces reaches magnesia by the thermal radiation form, again through the external thermal radiation of outer tube wall.This mode of heating is safe and reliable, the thermal efficiency is high, can satisfy the requirement of air heat in the passenger train carriage.But the electric furnace heating wire of prior art is positioned among the electric heating tube, and the energising initial stage is warm-up phase, and it is slower to heat up, the externally few and hysteresis of thermal radiation amount.After the integral body heating, only tube outer wall heat radiation, because surface area is little, radiating effect is poor, has bigger thermal inertia.The electric heating tube outside wall temperature is too high to be one of big factors of initiation fire, constitutes the hidden danger of passenger train and passenger safety.
Patent publication No.: CN03219602.4 " the nest plate heat dissipation type electric heater of colding pressing " also is one of typical technology scheme of prior art, this technical scheme is the heat exchange efficiency that further increases electric heating tube, outer tube wall equal intervals string cover fin at electric heating tube, this improves the temperature that structure can reduce electric heating tube outer tube wall about 20%, avoid the too high initiation fire accident of Yin Wendu, but this structure relative complex, manufacturing cost is big, must increase user's financial burden.
The utility model content
The utility model is primarily aimed at the deficiencies in the prior art, propose a kind of simple in structure, safe and reliable, rapid heat dissipation, the passenger train air heater that the thermal efficiency is high.
The utility model is achieved through the following technical solutions technical goal.
The passenger train air heater, it comprises electrode pile crown, electrode tip holder, limiting plate, housing, bearing, floor, conduit and electrical heating elements.Described housing is the cuboid that is provided with shutter, equidistantly matches the arrangement bearing along the inner plating of two long margin frames.Described floor is the bar shaped plate, and uniform through hole is installed conduit on the plate face, the floor two ends of placing vertically is connected to constitute on the housing inner chamber bearing catheter positioning is supported.Described conduit is tubular element, and the middle through hole of reserving treats that heating passes, and conduit is by the floor screens.Described electrode pile crown is single-head screw shape member, threaded one section outwardly, the other end connects heating inwardly.Its improvements are: described heating is flexible member, be bent into U-shaped during installation, one along passing the conduit of the heating of prone position U-shaped adjacent installation from floor, the electrode pile crown that electric heating element both ends connects is positioned at the same side, and from the electrode tip holder that limiting plate connects, pass, the equipped nut of the electrode pile crown that exposes is formed the external power supply pile crown, and 1～6 heating of installing side by side of every layer of configuration is established 3～9 layers before and after housing is interior altogether.
Electrode tip holder in the said structure, bearing and conduit are the insulation material and make, and electrode tip holder, bearing and conduit preferably ceramic material are made.The material of limiting plate is phenoplasts.Heating is made the cylindrical spring shape with the high-temperature alloy filament winding.
The utility model compared with prior art has following good effect:
1, the electrical heating elements of cylindrical spring shape is made easily, location insulation, stable performance, reliable;
2, electrical heating elements adopts the manufacturing of high-temperature alloy silk, and this structural table area is big, and heat exchange is fast, significantly reduces the thermal inertia of heating element heater;
3, the electrical heating elements surface temperature is low, avoids the initiation fire accident.
Description of drawings
Fig. 1 is the utility model structural profile schematic diagram.
The specific embodiment
Embodiment 1
The utility model is described in further detail with reference to the accompanying drawings and in conjunction with the embodiments below.
Passenger train air heater shown in Figure 1, it comprises electrode pile crown 1, electrode tip holder 2, limiting plate 3, housing 4, bearing 5, floor 6, conduit 7 and electrical heating elements 8.Described housing 4 is cuboid, shell is provided with shutter, inner chamber equidistantly matches along the inner plating of two long margin frames and settles bearing 5, uniform through hole is installed conduit 7 on the tabular floor 6 plate faces of bar shaped, floor 6 two ends of placing vertically are connected on the housing 4 inner chamber bearings 5 constitute conduit 7 positioning supports, because bearing 5 is ceramic material, makes and insulate between floor 6 and the housing 4.Described conduit 7 usefulness ceramic materials are made tubular element, and the middle through hole of reserving treats that heating 8 passes, and conduit 7 is formed insulation system by floor 6 screens.Described electrode pile crown 1 is single-head screw shape member, threaded one section outwardly, the other end connects heating 8 inwardly.Heating 8 in the utility model is flexible member, be bent into U-shaped during installation, one along passing the conduit 7 of heating 8 adjacent installation from floor 6 of prone position U-shaped, the electrode pile crown 1 that heating 8 two ends connect is positioned at the same side, and from the electrode tip holder 2 that the limiting plate 3 of phenoplasts material connects, pass, the electrode pile crown 1 equipped nut that exposes is formed the external power supply pile crown.Because of electrode tip holder 2 ceramic material manufacturing, make the electrode pile crown 1 and housing 4 insulation that are positioned at wherein.The utility model according to passenger train supporting requirement determine heating power, press heating power then and distribute every layer of electrical heating elements 8 quantity and hierarchical design.The present embodiment heating power is 3kw, and front and back are established 2 layers altogether in the housing 4.Every layer of equipped 2 heating 8 of installing side by side,
Present embodiment is applied in the compartment of passenger train of extremely frigid zones operation, and match power is 15kw.The configuration of making heating element heater 8 according to the big characteristics of match power designs, and its general structure is identical with embodiment 1, and only the configuration quantity of heating element heater 8 is different with the tandem number of plies.4 electrical heating elements 8 of every layer of configuration are established 9 layers before and after housing 4 inner chambers side by side altogether in the present embodiment, and being enough to satisfy provides hot-air to supporting passenger train, reaches design temperature fast.
The conventional attemperating unit of electrical heating elements 8 adapteds in the utility model, after the energising, electrical heating elements 8 is converted into heat with electric energy rapidly.Because electrical heating elements 8 usefulness high-temperature alloy filament windings are made the cylindrical spring shape, this structural table area is big, heat exchange is fast under the effect of moving air, make electrical heating elements 8 oneself keep lower temperature, guarantee that heater does not have the hot conditions of initiation fire, when creating a warm environment for passenger train, also create a security context for passenger train.
