Abstract
A train electric heater comprises an outer frame, a bracket, a heating part, a junction box and a temperature protection device. The heating part is 1-12 groups of heating bodies, each group of heating bodies is composed of electrode belts and PTC elements clamped between the electrode belts, and the outer sides of the electrode belts are provided with insulating layers and radiating strips. The gap between the insulating layers is filled with a temperature-resistant insulating moisture-proof sealant. The 1-12 groups of heating bodies can also adopt an electrothermal film and an alloy wire and are provided with an insulating and radiating device. The utility model discloses can not produce electrified body short circuit and overtemperature condition, can not damage because of vibrations, the radiating effect is good. The device is used for the winter operation of the train, improves the temperature of the carriage and has the obvious advantages of safety and reliability.
Description
The utility model relates to a kind of electric heater, especially for the electric heater of train air-conditioning.
For guaranteeing that the passenger is healthy and journey is comfortable, to send constantly into new wind in the railway car to increase air flow property, to improve air quality; In season in severe winter, must use temperature booster, to improve temperature in the compartment.Existing train air-conditioning temperature booster generally adopts tubular electric heating element as heater element, because the tubular electric heating element temperature rise can reach 300 ℃ even higher, in case control part and temperature protective device et out of order may cause fire, thereby safety, reliability are bad.
The purpose of this utility model is to overcome weak point of the prior art, and a kind of train electric heater of safe in utilization, good reliability is provided.
The technical solution of the utility model is: the train electric heater comprise housing, support, heating part, connection box and be arranged on electrical equipment control and return lead in temperature relay, temperature protector; improvements are that described heating part is 1～12 group of exothermic body; every group of exothermic body is made of power supply lead wire, electrode band and the PTC element that is clipped between the electrode band, and there are insulating barrier and heat sink strip in the electrode band outside.
The width of above-mentioned heat sink strip makes PTC element and electrode band not expose greater than the width of PTC element and electrode band, and safety is good.Be provided with the insulation shock absorption device between exothermic body and support, the housing, this device is generally rubber and ceramic.Fill with heatproof insulation and moisture aquaseal the gap between two insulating barriers, guarantees safety.Insulating barrier generally adopts aluminium oxide or inferior peace membrane material.Preferably there is mat in the electric heater outside.
The technical solution of the utility model also can be: described heating part is made up of 1～12 group of exothermic body, and every group of exothermic body is made of power supply lead wire and Electric radiant Heating Film, and there is heating panel the Electric radiant Heating Film both sides.
There are projection and groove part in the above-mentioned heating panel outside, improves radiating effect; Between Electric radiant Heating Film and the heating panel insulating barrier can be arranged.
The technical solution of the utility model can also be: described heating part is made up of 1～12 group of exothermic body, and every group of exothermic body is made of power supply lead wire and alloy silk, and there are insulating barrier and heating panel in the alloy silk outside.
More than in three kinds of schemes, described heating unit power lead-in wire and lead-in wire wiring part are in the middle of the insulation protection thing; Described insulation protection thing material is rubber or ceramic.
The utility model is owing to adopt PTC element, Electric radiant Heating Film, alloy silk etc. as exothermic body, and take corresponding structure design, can not produce charged body short circuit and overheating problem, can not damage because of vibrations, the while good heat dissipation effect, therefore come with the train air-conditioning temperature booster of tubular electric heating element compared with existing as exothermic body, have safe in utilization, the advantage of good reliability.
Further specify the utility model embodiment below in conjunction with accompanying drawing.
Fig. 1 is the utility model overall structure scheme drawing;
Fig. 2 is for adopting the exothermic body local structure scheme drawing of PTC element;
Fig. 3 is for adopting the exothermic body local structure scheme drawing of Electric radiant Heating Film or alloy silk.
As figure, the train electric heater is made of housing 1, support 3,6 groups of exothermic bodys 4, connection box 7, temperature relay 5, temperature protectors 6, and rubber pad 2 is arranged between exothermic body, housing, the support.Every group of exothermic body is made of power supply lead wire 14, electrode band 8 and the PTC element 10 that is clipped in therebetween, and there are insulating barrier 9 and heat sink strip 11 in the electrode band outside.The width of heat sink strip is greater than the width of PTC element and electrode band; Fill with heatproof insulation and moisture aquaseal gap between two insulating barriers.Insulating barrier adopts inferior peace membrane material.There is ceramic insulation seat 12 at the exothermic body two ends, and power supply lead wire and wire connecting portion branch are arranged in the middle of the insulation protective jacket of being made by rubber 13.
In the present embodiment, every group of exothermic body also can be made of Electric radiant Heating Film 15 and power supply lead wire, and there are insulating barrier 16, heating panel 17 in the Electric radiant Heating Film both sides, and there are projection and groove part 18 in the heating panel outside.
