Description

technical field [0001] Embodiments of the present invention relate to the technical field of electronic products, and in particular to a thermoelectric conversion device and electronic equipment. Background technique [0002] With the development of electronic devices such as mobile phones and tablet computers, their functions are becoming more and more powerful, and the systems are becoming more and more complex. Then, heat dissipation has become one of the problems that people need to solve urgently. Existing electronic equipment mainly uses the following measures to dissipate heat: first, optimize the circuit design to reduce power consumption, for example, optimize the load matching circuit of the power amplifier, and draw the load point of the power amplifier to the power amplifier The relatively high-efficiency load-pull area is used to reduce the operating current of the power amplifier, thereby reducing power consumption; the second is to dissipate heat in the form o...

Problems solved by technology

[0003] However, the inventors found that there are the following problems in the prior art: first, optimize the circuit design, and reduce the power consumption in the form of heat dissipation, which only alleviates the generation of heat sources to a certain extent, but does not fundamentally solve the problem of the main heat source. question

The second is to attach heat-conducting materials, which is equivalent to expanding the "point" heat source to the "surface" heat source, and spreading the concentrated heat sources evenly. This method does not reduce the total amount of heat in the equipment, and does not reduce Fundamentally dissipate heat; and, when in some superimposed application scenarios, such as playing games, wifi surfing the Internet and playing music at the same time, the temperature on the device casing is very high, which affects the life of electronic devices and the user experience is poor
