Description

Multistage refrigerating system for recycling circuit waste heat
Technical Field
The invention relates to the technical field of thermoelectric generation and refrigeration, in particular to a multistage refrigeration system for recycling circuit waste heat.
Background
With the increase of the popularity of electronic equipment, almost one mobile phone and one notebook computer are used at present. In addition, there are various intelligent electronic wearable devices, and various electronic devices such as large servers and desktop computers placed indoors. Electronic devices require a large amount of electrical energy to operate, and more than 40% of the electrical energy is ultimately consumed in the form of heat. When electronic equipment generates heat, the temperature of the equipment rises, the service performance of the equipment is influenced, meanwhile, the resource waste is also caused by the generation of heat, and the effective electric energy which can be really utilized is limited. In order to not affect the service performance of the equipment, the temperature of the equipment needs to be reduced, and some heat dissipation devices, such as fans, water cooling and other additional devices, are usually installed together with the electronic equipment, which is very common in the use of electronic equipment such as desktop computers, notebooks and the like. The use of these additional heat abstractor needs extra electric energy supply to there is certain defect, for example the fan can be because the long-term deposition causes the card stifled, and the noise grow during the rotation even causes can't rotate and burns out equipment, and the water cooling plant dismouting is complicated, and general user hardly accomplishes by oneself, and when seeking professional help the price is higher, and the scheduling problem that leaks appears easily still.

The method can improve the effective utilization rate of the electric energy to a certain extent, but still needs heat dissipation parts such as a fan, water cooling and the like to realize cooling, and the problems of the heat dissipation devices cannot be solved. Meanwhile, the electric energy obtained by the thermoelectric generation piece through waste heat conversion is not as large as the electric energy directly provided for the heat dissipation part by the power supply, and the same heat dissipation effect can not be achieved. The thermoelectric generation piece can only utilize the temperature difference between the cold end and the hot end to convert heat energy into electric energy, can not independently dissipate heat, and can not only help equipment to dissipate heat through the thermoelectric generation piece. After the equipment radiating effect reduces, the temperature difference between the cold end and the hot end of the thermoelectric generation piece can become small, the generating efficiency becomes low, the radiating effect of the radiating device is further influenced, and the vicious circle finally leads to the overhigh temperature of the equipment and can not be normally used. In addition, the prior art only collects waste heat for the core processor (CPU or GPU) of the circuit, but the circuit also has a plurality of heating elements, and the heat is wasted.
