Description

Technical Field

[0001] The utility model relates to the technical field of heat transmission, in particular to a high-efficiency heat radiation and electric energy conversion structure. Background Art

[0002] As the global energy crisis continues to deepen, oil resources are becoming increasingly depleted, and the harm of air pollution and global temperature rise is increasing, governments and automobile companies around the world generally realize that energy conservation and emission reduction are the main directions for the development of future automobile technology. In order to alleviate the above problems, the government vigorously advocates the promotion and use of new energy electric vehicles. Although they have certain advantages in energy conservation and emission reduction, there are still some shortcomings in their use; first, since new energy electric vehicles rely on battery packs to drive and travel, their endurance is limited. In addition, if the central control and other equipment are used during driving, the power consumption will be accelerated, further reducing its endurance; second, the use of nickel-hydrogen batteries and lithium-ion batteries has a relatively long life, but they need to be charged frequently, which causes inconvenience to use; third, the battery is charged through an external power supply, and then the battery's electricity is converted into mechanical energy to make the car move. When the battery is used up, it needs to stop and charge to keep the car moving.

[0003] In my country, there are extremely rich solar energy resources, especially in the equatorial and tropical regions. It is estimated that the energy of solar radiation reaching the earth's surface every day is equivalent to the energy produced by about 200 million barrels of oil; according to NASA estimates, the annual average energy of solar radiation to the earth is about 1.74×10^17 joules, which is about 5.5×10^12 joules per second; such abundant and convenient resources, applied to the field of new energy vehicles as part or all of their energy supply, can significantly improve the endurance of new energy vehicles; if a thermal radiation conversion device is added to the surface of the car, the endurance of the car will be greatly improved. At present, there is a single way of converting thermal radiation into electrical energy, which cannot make full use of natural resources, and traditional batteries have insufficient endurance and serious pollution to the environment.
