Traditional electronlmobil heating is to adopt the method add hot air, adopts resistance of electric energy heating exactly, by the distinguished and admirable heat of taking away resistive surface, does like this and has several shortcomings:
1, heat exchange efficiency is not high, Q=cm Δ t, and the specific heat of air is 1.06x10
3, specific heat of water is 4.2x10
3, under the situation of identical m and Δ t, the releasable heat of water is higher than air far away.
2, traditional battery-driven car heating power is not high, battery-driven car is power with electric power, the voltage of its consumer is thrown away and is 12V, electric heater with 2000W, its electric current will reach 167A, in order to guarantee that big like this electric current need select enough thick electric wire for use, so caused the electro heat of whole battery-driven car not too large.
3, in battery-driven car heating, can't constitute the loop from the air of outdoor collection, can't realize the adjusting of its temperature.
Summary of the invention
The purpose of the embodiment of the invention is the defective at above-mentioned prior art, provide a kind of reasonable in design, cost is low, save the heating device of electric automobile of energy consumption,
The technical scheme taked of the present invention is to achieve these goals: a kind of heating device of electric automobile, comprise expansion tank, the outlet pipe of described expansion tank connects electric heater by water pump, and the induction pipe of described expansion tank connects electric heater by described water pump.
Described water pump is an electronic water pump.
Described electric heater comprises the heating core body, is provided with at least one heating rod in the described heating core body.
Described heating rod connects the car load power supply.
The electric wire outer end of described heating rod is provided with aluminum pipe, and described aluminum pipe captive joint heating core body is provided with the injection moulding waste material between described aluminum pipe and the electric wire.
Described Al pipe butt welding is in described heating core body.
Be provided with temperature sensor in the described heating core body.
Further, control heating rod electric power starting or closure according to the measurement temperature of described temperature sensor.
The beneficial effect that the technical scheme that the embodiment of the invention provides is brought is:
1, by the closed water route of design heating arrangement, can reduce extraneous interference as far as possible, utilize the electric energy that carries on the car fully, energy efficient.
2, temperature sensor is set after, control water temperature reaches needed heating amount easily.
3, compare with the method for traditional heating air,, can just obtain comfortable temperature at short notice by constantly adding the water in the hot water circulation.
4, cost of development of the present invention is lower, and all materials can obtain on market.
Description of drawings
Fig. 1 is the heating device of electric automobile scheme drawing that provides in the embodiment of the invention 1;
The structural representation of the electric heater that Fig. 2 provides for the embodiment of the invention;
Fig. 3 is that A-A among Fig. 2 is to view.
Among the figure: 1 expansion tank, 2 induction pipes, 3 outlet pipes, 4 water pumps, 5 electric heaters, 5.1 heating core bodys, 5.2 heating rods, 6 electric wires.
The specific embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, embodiment of the present invention is described further in detail below in conjunction with accompanying drawing.
Referring to Fig. 1, a kind of heating device of electric automobile comprises expansion tank 1, connects on the expansion tank 1 and imports and exports 2,3, and induction pipe 2 connects electric heater 5 by water pump 4, and outlet pipe 3 connects electric heater 5 by water pump 4.
Expansion tank is identical with the principle of traditional combustion engine, and the effect of this expansion tank water tank is for circulation waterway adds water and exhaust, can adopt expansion tank commonly used to get final product.Water pump preferred electron water pump selects for use electronic water pump to help controlling by circuit the unlatching of water pump, is convenient to operation, and when the user opened heating, electronic water pump work for the water in the circulation waterway provides power, constituted circulation.The advantage that the present invention has is reasonable in design, cost is low.
Referring to Fig. 2 and Fig. 3, electric heater 5 comprises heating core body 5.1, is provided with at least one heating rod 5.2 in the heating core body 5.1.Imbed the heating rod 5.2 of a 2000W～3000W in the hydroecium of heating core body 5.1 1 ends, the concrete power of heating rod 5.2 can come requirement according to the load that battery-driven car can bear, and heating rod 5.2 is used for heating the water that flows through heating core body 5.1.In in heating rod 5.2 is imbedded heating core body 5.1, can be at electric wire 6 outer ends of heating rod 5.2 parcel one deck aluminum pipe, with welding gun this aluminum pipe and heater core inside are firmly welded, fill with the injection moulding waste material in the space between aluminum pipe and the electric wire, guarantees that sealing effectively.
