Description

Technical Field

[0001] This invention relates to the field of new energy vehicle technology, and in particular to a waste heat recovery generator for new energy vehicles. Background Technology

[0002] Generators are widely used in society. Current power generation technologies typically employ thermal power, wind power, and solar power. Thermal power causes significant pollution to the environment and air; wind power has high environmental requirements, requiring wind to generate electricity, resulting in low efficiency; solar power requires high sunlight levels, and the aforementioned generators are not well-suited for use in new energy vehicles. While new energy vehicles have significantly improved energy conversion efficiency compared to traditional internal combustion engines, energy loss still occurs during vehicle operation. The driving range of new energy vehicles primarily relies on increasing the energy density of their batteries and the energy conversion efficiency. With continuous innovation and improvement in my country's new energy vehicle technologies, the energy density of new energy batteries has significantly increased. However, higher battery energy density also leads to instability, increasing the risk of battery failure and accidents. Therefore, improving battery energy density remains a complex and challenging task at present, with the only effective approach being to enhance energy conversion efficiency. Summary of the Invention

Detailed Implementation

[0025] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] like Figure 1-6 As shown, a waste heat recovery generator for new energy vehicles includes a power source mechanism 1 and a power generation mechanism 2. The power source mechanism 1 is connected to the power generation mechanism 2. The power source mechanism 1 includes a rotor 101, a permanent magnet 102, a cooling cavity 103, a heating cavity 104, and a forked arm 105. A plurality of slots 106 are provided on one side of the rotor 101. One end of the permanent magnet 102, the cooling cavity 103, and the heating cavity 104 is provided with a connecting end 107. The permanent magnet 102, the cooling cavity 103, and the heating cavity 104 are evenly distributed on one side of the slots 106. The forked arm 105 is provided on one side of the rotor 101 and is connected to the rotor 101 through a drive shaft 3, which enables the new energy vehicle to improve energy conversion efficiency and increase the driving range of the new energy vehicle.

[0027] The cooling chamber 103 is provided with a first inlet 1031 and a first outlet 1032 at both ends, and the first inlet 1031 and the first outlet 1032 are respectively connected to the cooling water tank; the heating chamber 104 is provided with a second inlet 1041 and a second outlet 1042 at both ends, the second inlet 1041 is connected to the cooling channel of the motor unit, and the second outlet 1042 is connected to the cooling water tank. The heat energy of the coolant in the channel is fully utilized to convert the heat energy into electrical energy, thereby improving the energy conversion efficiency and saving energy.

[0028] The power generation mechanism 2 includes a rotor core 201, a stator 202, an excitation coil 203, and a stator winding 204. The excitation coil 203 is disposed on the rotor core 201, and the rotor core 201 is disposed in the inner cavity of the stator 202. One end of the rotor core 201 is connected to the forked arm 105. The stator winding 204 is disposed on the inner wall of the stator 202.

[0029] The excitation coil 203 is provided with a first slip ring 2031 and a second slip ring 2032 at its two ends, and the first slip ring 2031 and the second slip ring 2032 are provided with a first brush 2033 and a second brush 2034, respectively; the two ends of the stator winding 204 are respectively connected to the load 205.

[0030] In addition, the cooling cavity 103 and the heating cavity 104 are respectively provided with flow channels, and a gap 4 is provided between the flow channels and the groove 106.

[0031] Furthermore, the rotor 101 is made of nickel alloy. Nickel alloy is a soft magnetic material that weakens as the temperature rises and regains its magnetism when the temperature returns to normal. When the rotor 101 is partially heated in the heating cavity 104, it loses its magnetism, resulting in a magnetic strength difference between the rotor 101 and the permanent magnet 102. The permanent magnet 102 partially attracts the cooling cavity 103, thereby driving the rotor 101 to rotate. Then, after passing through the cooling cavity 103, the rotor 101 returns to normal temperature and regains its magnetism.

[0032] In addition, gap 4 is filled with liquid thermally conductive nanofluid to improve the heat exchange effect of the cavity.

[0033] Furthermore, the first brush 2033 and the second brush 2034 are respectively connected to the power supply 5 to supply power to the excitation coil 203, so that the rotor core 201 can have magnetism under the action of the excitation coil 203.

[0034] In addition, a sealing element is provided between the cooling chamber 103 and the heating chamber 104 and the rotor 101 to improve the sealing effect.

For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
