Embodiment Construction

[0011] figure 2 , image 3 As shown, in the automobile waste heat power generation device of the present invention, the inner side of the round tubular soft iron pipe 141 of its generator 14 is pasted with many new alloys 142 that are centrally symmetrical with the center line of the soft iron pipe 141 as the line of symmetry; Wire slots are surrounded between the new alloys 142, and the coils 144 are installed in the wire slots. There is a cold and heat exchange hole running through the whole new alloy 142 at the central position of each new alloy 142 section. A bar-shaped rare earth magnet 143 is attached to the palm surface of each novel alloy 142 outside, and the magnetic polarity of the rare earth magnet 143 attached to the palm surface of the adjacent novel alloy 142 is opposite; A steel pipe 145 with the same core line as the soft iron pipe 141. There are insulation films between the new alloy 142 and the rare earth magnet 143 and between the new alloy 142 and the s...

Abstract

The invention discloses a power generating device by waste heat of automobiles. A plurality of novel alloy bars are attached to the inner side of a circular iron hose of a power generator, coils are mounted between adjacent novel alloy bars and arranged in coil slots formed by adjacent novel alloy bars in a surrounded manner, heat and cold exchange holes are arranged on the novel alloy bars, an elongated rare earth magnet is attached on an outer face side of each alloy bar, magnetic polarities of the rare earth magnets on the face sides of the adjacent novel alloy bars are opposite, the other magnetic polarity surfaces of the rare earth magnets are wrapped on steel pipes, and the power generator is provided with an outer casing. The novel alloy bars are non-magnetic substances at a certain low temperature while are magnetic substances at a certain high temperature. When the rare earth magnets are close to the novel magnetic alloy bars, magnetism of the novel magnetic alloy bars is doubled. The novel alloy bars have magnetism after being heated by tail gas or a heat medium liquid in a cylinder liner of an automobile and have no magnetism after being cooled by cold air with water mist or refrigerant liquid, and high alternating current can be produced in the coils by repeating the above steps and can be used as power force for electric automobiles.

Description

Technical field: [0001] The invention relates to an automobile waste heat power generation device. Background technique: [0002] The utility model patent ZL201020204766 "An Automobile Waste Heat Power Generation Device" uses semiconductor thermoelectric power generation technology in the waste heat power generation device of automobile exhaust. This waste heat power generation device has a simple structure, but the power generation is extremely small. It can only charge the 12-volt car battery and cannot be used as driving power for plug-in hybrid vehicles. We know the ideal Carnot cycle: the efficiency of a car engine is 38%, and the efficiency of a diesel engine is 42%, that is to say, about 40% of the heat energy of fuel combustion is converted into mechanical energy, and the rest of the heat is discharged from the exhaust and transferred to the cylinder ,piston. When a car with a maximum power of 90 kW is running, how much energy will be lost in the form of waste hea...
