Abstract
The invention provides an electric heating device for a passenger car. The electric heating device comprises a casing and a heating tube, wherein the heating tube comprises a casing body, electric heating wires are arranged in the casing body, a sealed hollow cavity is arranged in the electric heating wires, and a carbon fiber heating body is filled in the sealed hollow cavity. In heating, the electric heating wires and the carbon fiber heating body heat together to performing heating, so that temperature rising speed of the heating tube can be greatly improved. In addition, the electric heating device of the passenger car is even and fast in heating, high in insulating strength and safe to use, and the electric heating conversion efficiency is as high as 90%.
Description
Technical field
The present invention relates to a kind of heating arrangement, particularly a kind of passenger vehicle electric heater unit belongs to the technical field of temperature booster.
Background technology
Along with the adjustment development of Chinese Railway, more and more higher to the traveling comfort in the railway car and security requirement.The heater element that adopts in the present domestic high-grade railway car tubular electric heating elements that adopt external import more.Because tubular electric heating element belongs to easily-consumed products, tubular electric heating element easily damages after use a period of time needs often to change, but because the procurement cycle of import parts is long, cost is high.Heating arrangement of the prior art, comprise shell, heating pipe, wherein, described heating pipe, comprise housing, be provided with electrical heating wire in the housing, be filled with insulating material in the described housing, insulating material is included in the electrical heating wire periphery, the electric heating tube programming rate of this structure is slower, thereby, prolonged preheating time of a/c system during use.
Summary of the invention
Technical matters to be solved by this invention provides the passenger vehicle electric heater unit that a kind of programming rate is fast, heat is even and simple in structure.
For above-mentioned technical matters, a kind of passenger vehicle electric heater unit of the present invention comprises shell, heating pipe, described heating pipe comprises housing, is provided with electrical heating wire in the described housing, wherein, be provided with sealed cavity in the described electrical heating wire, be filled with carbon fiber exothermic part in the described sealed cavity.
Above-mentioned passenger vehicle electric heating tube, wherein, described housing outer peripheral face is provided with double wedge.
Above-mentioned passenger vehicle electric heating tube, wherein, the top of described double wedge is arc.
This practicality can realize following beneficial effect: owing to being provided with sealed cavity in the described electrical heating wire, be filled with carbon fiber exothermic part in the described sealed cavity, during heating, the electrical heating wire heating, carbon fiber exothermic part also heats simultaneously, thereby, greatly improved the programming rate of heating pipe, in addition, the present invention generates heat evenly, and electric heating conversion efficiency is high, reaches more than 99%, heating is fast and dielectric strength is high, uses safety; Because described housing outer peripheral face is provided with double wedge, increased the dissipating area of heating pipe again, heat is comparatively fast conducted, thereby, further improved programming rate of the present invention, again because the top of double wedge is arc, avoid causing punch through, thereby, safety of the present invention improved.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of heating pipe of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing invention is described further.
As shown in the figure, for above-mentioned technical matters, a kind of passenger vehicle electric heater unit of the present invention comprises shell 10, heating pipe 11, heating pipe 11 are horizontally installed in the shell 10, heating pipe 10 comprises housing 1, be provided with electrical heating wire 2 in the described housing 1, electrical heating wire 2 periphery coated insulation materials 6 are provided with sealed cavity 3 in the described electrical heating wire 2, be filled with carbon fiber exothermic part 4 in the described sealed cavity 3, owing to being provided with sealed cavity 3 in the described electrical heating wire 2, being filled with carbon fiber exothermic part 4 in the described sealed cavity 3, during heating, electrical heating wire 2 heatings, carbon fiber exothermic part 4 also heats simultaneously, thereby, greatly improved the programming rate of heating pipe, in addition, the present invention generates heat evenly, and electric heating conversion efficiency is high, reaches more than 99%, heating is fast and dielectric strength is high, uses safety; Described housing 1 outer peripheral face is provided with double wedge 5, and the top of described double wedge 5 is arc.
