Abstract
The utility model relates to the technical field of warming equipment, in particular to an electric warming device which can be applied in a narrow space, of a railway vehicle. The electric warming device comprises a framework, an electric device and a bottom plate, wherein the bottom plate is installed on the bottom of the framework; the electric device is located on the outer side of the framework, and is fixedly arranged on the bottom plate; an air inlet is formed in the framework; an air outlet is formed in the bottom plate; an installation bracket, a PTC (Positive Temperature Coefficient) heating body close to the air outlet and an axial flow fan arranged at the air inlet are arranged in the framework; the installation bracket is fixedly arranged on the inner wall of the framework; the PTC heating body is connected into the framework through the installation bracket. The electric warming device, depending on the heating of the PTC heating body, adopts forced ventilation for heat radiation, so that a cab is kept at a normal room temperature; compared with an existing electric warmer externally hung outside a guest room, the device is simpler in structure, occupies no use space of the cab, is good in heat radiation, is capable of fully utilizing energy and is higher in safety and reliability.
Description
Technical field
The utility model relates to the technical field of heating installation, especially a kind of rolling stock electricity heating arrangement that can be applied in small space.
Background technology
Along with developing rapidly of railway traffic, the facility structure design in train is humanized, in order to make the bulk temperature in vehicle remain on normal room temperature, can in guest room, dispose electric heater (resistance wire type).
What in guest room, generally adopt at present is the electric heater (resistance wire type) that external hanging type is installed, not only heating effect is undesirable for this kind of structure heating arrangement, the energy can not make full use of, and the size of heating arrangement itself is bigger than normal, limit its installing space, in this narrow space of driver's cab, this kind of electric heater is installed, had a strong impact on the usage space of driver's cab.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provide in a kind of operating console that can be placed on driver's cab, conserve space, and the safe and reliable rolling stock for rolling stock driver's cab electricity heating arrangement.
The utility model solves the technical scheme that its technical matters adopts: a kind of rolling stock electricity heating arrangement, for the heating in vehicle, comprise framework, electric apparatus and be arranged on the base plate of base of frame, electric apparatus is positioned at the outside of framework and is fixed on base plate, on described framework, have ventilation inlet, on base plate, have air outlet, in framework, be provided with mounting bracket, the PTC exothermic body close with air outlet and be arranged on the prerotator at ventilation inlet place, mounting bracket is fixed on the inwall of framework, and PTC exothermic body is connected in framework by mounting bracket.
Described mounting bracket is connected by rivet with framework.
Described PTC exothermic body is connected by screw with mounting bracket.
Described heating arrangement is arranged in operating console.
The beneficial effects of the utility model are: the utility model relies on the heating of PTC exothermic body, employing forced ventilation heat radiation, make driver's indoor temperature remain on normal room temperature, compared with existing guest room external hanging type electric heater, structure is more simple, do not take the usage space of driver's cab, thermal diffusivity is good, energy utilization is abundant, have higher safety and reliability.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: 1. framework, 11. ventilation inlets, 2. base plate, 21. air outlets, 3. mounting bracket, 4.PTC exothermic body, 5. prerotator.
The specific embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
Rolling stock electricity heating arrangement as shown in Figure 1, for the heating in vehicle, comprise framework 1, electric apparatus and the base plate 2 that is arranged on framework 1 bottom, electric apparatus is positioned at the outside of framework 1 and is fixed on base plate 2, on framework 1, have ventilation inlet 11, on base plate 2, have air outlet 21, in framework 1, be provided with mounting bracket 3, the PTC exothermic body 4 close with air outlet 21 and the prerotator 5 that is arranged on ventilation inlet 11 places, PTC exothermic body 4 is connected by screw with mounting bracket 3, mounting bracket 3 is fixedly connected on by rivet on the inwall of framework 1, prerotator 5 fixes by rivet with framework 1.
PTC exothermic body 4 is Novel heating bodies of a kind of constant temperature that insulate, be stained with two metal sheets (as copper, aluminium, stainless steel substrates) in the both sides of PTC heat element and draw two wires as powered electrode, while is at the outer insulation heat proof material that puts of metal electrode film, it is simple in structure, get final product persistent fever without separately adding temperature regulating device, there is good insulation preformance, safe and reliable, power stability, uses the features such as voltage is wide.
The utility model can be directly installed in operating console, does not take limited usage space in driver's cab, improves the comfort level of driver's cab, easy for installation, is also convenient to follow-up maintenance.
The utility model mainly conducts heat by forced air convection current, prerotator 7 sucks cold air, cold air enters from ventilation inlet cover plate, cold air enters in framework by ventilation inlet 11, PTC exothermic body 4 heats air, then from prerotator 5, hot air is blown out toward driver's cab from air outlet 21, thereby has guaranteed the temperature of driver's cab, make it keep constant temperature, the energy can be made full use of.
The utility model is different from resistance wire type electric heater, while continuing heat supply under the condition that ventilation inlet 11 or air outlet 21 are blocked by foreign object, air outlet 21 surface temperatures can not raise along with the time, power and the temperature that can automatically regulate heating arrangement self, there will not be and scald people or damage product and so on.
Above-mentioned embodiment is only explanation technical conceive of the present utility model and feature; its object is to allow person skilled in the art can understand content of the present utility model and be implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
