Description

technical field [0001] The invention belongs to the technical field of ultrasonic wireless power transmission, and in particular relates to a cooling system and method for wireless power supply. Background technique [0002] In recent years, wireless power transfer technology, as an emerging power supply technology, has received extensive attention and research. Among them, wireless power transmission technology uses intermediate carriers such as high-frequency magnetic fields, electric fields, and ultrasonic waves to transmit electrical energy from power sources to electrical equipment in an electrically isolated manner. However, in the metal medium, electromagnetic waves are shielded and cannot propagate, so that the relatively mature electromagnetic induction coupling and electromagnetic resonance wireless power supply technologies at this stage cannot be effectively applied. [0003] Ultrasound, as a mechanical wave, can propagate in various media such as air, water, an...

[0004] The purpose of the present invention is to solve the above-mentioned defects in the prior art. The present invention proposes a heat dissipation system for wireless power supply. During the wireless power supply process of the ultrasonic wireless power supply device, the working temperature of the sealed metal shell is monitored in real time. When the normal working temperature is exceeded, the heat dissipation system is started to dissipate heat, so that the working temperature of the wireless power supply drops and continues to be kept at the normal working temperature, achieving the purpose of continuous cooling and stable power supply, effectively solving the problem of electronic equipment inside the closed metal casing.
