Portable wearable temperature difference power generation device

Abstract

The invention discloses a portable wearable temperature difference power generation device. The portable wearable temperature difference power generation device is composed of a heat collector, a thermoelectric module and a radiator, and the total thickness of the portable wearable temperature difference power generation device is smaller than 10 mm. The thermoelectric module acts at the temperature ranging from 10 DEG C to 60 DEG C. The heat collector comprises a bottom heat plate and a heat conduction base arranged between the bottom heat plate and the end face of the thermoelectric module in a direct-contact mode. The bottom heat plate is a meshed good heat conductor. The radiator comprises a radiating face and a radiating base arranged on the cold end face of the thermoelectric module in a direct-contact mode. The thermoelectric module is a chip integrated with a voltage stabilization module. Interval-type intensive array-type thermocouple pairs are arranged in the chip. The voltage stabilization module is externally connected with an energy storage unit, an LED indicator lamp and a USB socket. By the application of the temperature difference power generation device, any heat energy can be utilized for power generation, no noise or consumption is generated, the size is small, an interlayer is thin, the portable wearable temperature difference power generation device is convenient to wear, carry, store and assemble, the gap of the wearable electronic energy field is filled, and the portable wearable temperature difference power generation device is environmentally friendly, wide in application range, long in working life, and also suitable for being independently used in a field or being used by being integrated with cookers.

Description

technical field [0001] The invention relates to a power generation device, in particular to a realization scheme for a new application of thermoelectric power generation in wearable and portable daily necessities, and belongs to the field of thermoelectric power generation applications. Background technique [0002] Traditional fuel energy is decreasing day by day, and its harm to the environment is becoming more and more prominent. At present, there are 70 million people without electricity in my country who are far away from the grid power system. Today, the whole world is turning its attention to renewable energy, hoping that renewable energy can change the energy structure of human beings, provide sustainable energy, and solve the problem of distributed power generation going to the countryside. [0003] The history of the evolution of power generation technology includes traditional water wheel driven turbine generators, steam driven generators, internal combustion eng...

AI Technical Summary

Problems solved by technology

[0006] 1) The equipment used is relatively expensive, and the one-time investment cost is high; or the equipment is relatively special, some of which are specially designed for a certain micro-thermoelectric module manufacturing process, and it is not easy to achieve mass production

[0007] 2) The production process is not based on thermoelectric block materials that can be bought at low prices in the market, but on powder or simple elements, and is synthesized by condensation, powder sintering, thin film and other preparation technologies, which increases the Technical difficulty and product quality risk

[0008] 3) There are many process steps, and some processes span multiple technical fields such as material synthesis, precision machining and microelectronics, and product quality management is not easy to carry out

[0009] 4) Some processes have high requirements on the technical level and proficiency of operators, and the operating costs are high

[0010] 5) The existing microelectronics process generally has the problem of low effective heat transfer area in the application of micro thermoelectric modules, resulting in generally low power density
