Passive, self-driven, multifunctional, intelligent and energy-saving window

The invention discloses a passive, self-driven, multifunctional and intelligent energy-saving window, belongs to the technical field of energy-saving windows and aims at solving the problem of large heat loss of external building windows in building energy consumption. A window body comprises an external window body frame, an internal window frame, sandwiched side walls and window glass, the external window body frame, the internal window body frame and the sandwiched side walls form the window body of a groove structure, the window glass is fixed on both the external window body frame and the internal window body frame, one temperature difference power generating piece is fixed on the internal wall of the external window body frame, another temperature difference power generating piece is fixed on the inner wall of the internal window body frame, and a heat radiating plate is connected between the temperature difference power generating pieces in a clamped manner and fixed to the sandwiched side walls; a photovoltaic power generating piece is adhered on the external wall of the external window body frame, a multi-source electric energy collector is fixed on the external surface of each sandwiched side wall, a single chip microcomputer is fixed on the external surface of the internal window body frame, a VO2 thin film covers the internal-side surface of the window glass on the internal window body frame, and electric heating lines which are distributed in a snakelike manner are arranged on the surface of the VO2 thin film. The window is energy saving.
