In recent years, the forklift is facing two challenges energy saving and environmental. However, the hydraulic forklift has low transmission efficiency and energy efficiency. To solve the problem, this paper proposes an approach for the lifting hydraulic cylinder replaced by ball screw device.The lifting system is controlled directly with an electric motor drive instead of pump. First, we analyzed...
A combination of PV-TE (photovoltaic and thermoelectric) technologies can effectively broaden the use of solar spectrum as well as increase the total power output. One of the keys is to build a large temperature difference across the thermoelectric module with controlled heat flow. In this paper, a thermal concentrated PV-TE hybrid system is fabricated with optimized thermal management. The heat flow...
Thin-film STEGs (solar thermoelectric generators) show promise in effective use of solar energy as a power supply for wireless sensors and microscale devices. This paper reports a simulation procedure that aims to identify desirable heat flow and temperature distribution to improve the performance of thin-film STEGs. The temperature distribution, heat flux, and voltage of a thin-film STEG are simulated...
