Abstract
The utility model discloses an electric heater for a bullet train or a locomotive, and belongs to the technical field of air heating. The electric heater for the bullet train or the locomotive comprises a shell (1), heating elements (2), a power junction box (3), a temperature control device (4) and the like. Fresh air which is led in through a fresh air opening, and circulating air inside the bullet train or the locomotive are mixed before being sucked into the electric heater, and are heated by the electric heater, the heated air is sent to grids, the hot air is supplied to the interior of the bullet train or the locomotive, the internal temperature of the bullet train or the locomotive can slowly rise, and the internal temperature of the bullet train or the locomotive is automatically adjusted by a temperature adjuster, and a certain comfortable temperature inside the bullet train or the locomotive is kept. The electric heater for the bullet train or the locomotive is firm and reliable in structure, unique in design, high in heating efficiency, good in heat dissipation performance and free of consumption of oxygen, energy is saved, environmental friendliness is achieved, and the electric heater for the bullet train or the locomotive completely meets the use requirements of the CRH series of bullet trains and the locomotives.
Description
Technical field
Motor-car or an electricity for locomotive temperature booster, the air heating apparatus for CRH motor-car series, high ferro and locomotive, belongs to air heating technical field.
Background technology
Motor-car, electricity for locomotive temperature booster are applicable to motor-car, high ferro and other series of locomotives project.This motor-car, electricity for locomotive temperature booster belong to air heating system, and extraneous air heats through electric heater, and the air after being heated is sent in car, make vehicle interior temperature increase, and by heat regulator, automatically regulate vehicle interior temperature, keep certain comfort temperature in car.
Summary of the invention
The purpose of this utility model is to provide a kind of motor-car or locomotive air heating system, meets the requirement of omnibearing air heating in motor-car, locomotive.
The technical solution of the utility model: a kind of motor-car or electricity for locomotive temperature booster, be comprised of housing 1, heat element 2, electric source connecting box 3, attemperating unit 4 etc.Heat element 2 is by bolted on housing 1, and attemperating unit 4 is connected with heat element 2 by wire, pig-tail wire access electric source connecting box 3;
Housing 1 adopts the material of high-strength corrosion-resisting to be welded.
Heat element 2 adopts any in three kinds of tubular electric heating elements, PTC element, electric hot plate, can choose according to actual needs.Each heat element can work alone, and under windless condition, its surface temperature is all lower than 165 ℃.
Box body and the lid of electric source connecting box 3 are bolted fit sealing; Cage spring terminal block in connection box chamber is for the connection of wire; Box body and lid all adopt Metal Material Welding synthetic.
Attemperating unit 4 adopts two-stage temperature protective device, and the first order is for can automatically recover formula Overtemp. protector, and the second stage is for can not automatically recover formula Overtemp. protector.
Between heat element 2, electric source connecting box 3 and attemperating unit 4, by wire circuit, connect, wire circuit is fastened on electric heater inner chamber by pipeline, realizes heating function; The output signal centralized displaying of each wire circuit is in electrical control cabinet, once electric heater operational process breaks down, the mode of operation of electrical control cabinet, instrument and indicator lamp show that situation can show various failure messages in time, allow the interior staff of car understand the mode of operation of heating system.
The beneficial effects of the utility model: simple in structure, design is unique, and the efficiency of heating surface is high, and perfect heat-dissipating does not consume oxygen, temperature control multi-stage protection, long service life, meets the operating needs of motor-car series, high ferro and locomotive completely.
