A heating device for a rail vehicle is characterized in that: the temperature control device comprises a box body, a cover plate, a heater, a fan, a middle partition plate, a temperature controller, a primary protection device and a secondary protection device;
The heater is arranged at the front part in the box body, the fan is arranged at the rear part in the box body, a cavity is arranged on the inner wall of one side of the box body, a primary protection device is arranged on the inner wall of the other side of the box body, the temperature controller is arranged in the cavity, and a secondary protection device is arranged on one side of the triangular cavity;
The middle partition board is arranged on the box body and comprises a sealing part at the front part and a guide ring at the rear part;
the cover plate is arranged on the middle partition plate, and an air outlet is arranged on the cover plate and corresponds to the position of the fan.
furthermore, two baffles are arranged on the upper surface of the sealing part, and an air cavity is formed between each baffle and the cover plate.
Further, the chamber is triangular.
Further, the heater is a heating coil.
Furthermore, the air outlet is a through hole in an annular array.
compared with the prior art, the beneficial effects of the utility model are that:
1. The utility model relates to a heating device for rail vehicle, through heating coil and fan cooperation, under the direction of water conservancy diversion circle and annular array's exhaust vent effect, the hot gas flow is stable, even.
2. The utility model relates to a heating device for rail vehicle, when the fan is malfunctioning, the temperature in the box continuously rises, when the temperature controller detects the threshold value of 90 ℃, the triggering of one-level protection device cuts off the power supply of heater; in special cases, when the primary protection device and the fan are out of order, the temperature controller detects a 140 ℃ threshold value, the secondary protection device is triggered to cut off the power supply of the heater, and the stability of the device is ensured by double protection.
Drawings
fig. 1 is a schematic structural view of a heating device for a rail vehicle according to the present invention.
fig. 2 is an exploded view of a heating device for a rail vehicle according to the present invention.
In the figure:
The device comprises a box body 1, a chamber 1.1, a cover plate 2, a heater 3, a fan 4, a middle partition plate 5, a sealing part 5.1, a baffle 5.1.1, a flow guide ring 5.2, a temperature controller 6, a primary protection device 7 and a secondary protection device 8.
Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
Referring to fig. 1-2, the utility model relates to a heating device for a rail vehicle, which is arranged on the side plates of two adjacent carriages, and comprises a box body 1, a cover plate 2, a heater 3, a fan 4, a middle clapboard 5, a temperature controller 6, a primary protection device 7 and a secondary protection device 8;
The heater 3 is arranged at the front part in the box body 1, the fan 4 is arranged at the rear part in the box body 1, a triangular cavity 1.1 is arranged on the inner wall of one side of the box body 1, a primary protection device 7 is arranged on the inner wall of the other side of the box body 1, the temperature controller 6 is arranged in the cavity 1.1, and a secondary protection device 7 is arranged at one side of the triangular cavity 1.1;
