Abstract
The utility model relates to a hot air heater for heating in a locomotive cab, which is a box body type hot air heater matched with a hidden pipe to be used and comprises a box body, a contactor, a positive temperature coefficient (PTC) heating element, a voltage stabilizing controller, a centrifugal fan, an air duct and a protector. The hot air heater is of a box body type hidden heating structure which is matched with a locomotive hidden pipe to be used, an air outlet opening is arranged at the bottom of the box body, air return openings are arranged at both sides and the top, the centrifugal fan is adopted, the wind quantity is large, the heat can be fast radiated out, meanwhile, the hot air outlet from outlet openings at the bottom of a driving position through the pipeline air supply can be ensured, the PTC semiconductor heating element is adopted, the electricity and heat conversion efficiency is high, the temperature rise is fast, the heat sensing is strong, and the hot air heater is safe and reliable. The hot air heater is regulated through two gears, one gear is weak heating, the other gear is strong heating, an overheating and short circuit protection device is arranged in the hot air heater, and the hot air heater is specially designed for large regulation fluctuation range of the railway network voltage input power supply.
Description
Technical field
The utility model relates to the indoor heating hot-air heater of a kind of trainman
Background technology
The most of blowing mode that adopts of the heating installation that uses on the existing locomotive, wall-hanging structure, the heating installation of this kind structure heats up slow, and electric conversion efficiency is not high, has taken the indoor space of trainman simultaneously.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defective, a kind of quick heating, electric conversion efficiency height are provided, take up room little, with the indoor heating hot-air heater of the matching used trainman of locomotive hidden pipe.
The technical solution of the utility model: the indoor heating hot-air heater of a kind of trainman, it is characterized in that: this hot-air heater is and the matching used box-type hot-air heater of hidden pipe that it comprises casing, contactless switch, PTC heat element, voltage stabilizing control setup, centrifugal blower, air channel and fender guard; The voltage stabilizing control setup comprises voltage stabilizing control desk and voltage transformer, this voltage stabilizing control desk is made up of voltage signal sampling and voltage-regulation unit, fender guard is overheated and short-circuit protection, it comprises coolant-temperature switch circuit breaker and electric capacity, and the coolant-temperature switch in this fender guard, circuit breaker and capacitor bank dress are arranged on the air channel;
Described PTC heat element is installed in bottom half air outlet place, centrifugal blower is installed in the top of PTC heat element, air channel on the centrifugal blower is arranged on bottom half and communicates with the locomotive hidden pipe, two contactless switchs and voltage stabilizing control desk are installed on the casing backboard, voltage transformer is installed on the box bottom, and the voltage transformer lower end is provided with connection terminal.
This hot-air heater profile is especially at new Ss9 space structure design, and novel concealed type heats, and with the supporting use of hidden pipe, air outlet is located at bottom half, and return air inlet is located at casing both sides and top.Top board, biside plate and front plate are the removable jew assembling, are convenient to assembling and maintenance.Exothermic body adopts PTC quartz conductor exothermic material, has that electric conversion efficiency height, quick heating, hotness are strong, the flames of anger, unglazed consumption, characteristics such as safe and reliable.The centrifugal blower of selecting for use especially, air quantity is big, and the heat that can send heat element rapidly comes out, and has suitable blast and guarantee that the pipeline air-supply is from driving bottom, the position air outlet warm braw that comes out.Hot-air heater has two retaining regulation and control, and a retaining heats a little less than being, a retaining is for forcing heat, in adorn overheated and short-circuit protection, aim at and regulate the railway network and press the big and design-calculated of input power-supply fluctuation scope.
