Graphene micro-nano laminated phase change material energy-saving louver

Abstract

The invention discloses a graphene micro-nano laminated phase change material energy-saving louver, which comprises a bottom beam, a plurality of phase change material louver blades, a louver lifting rope, a ladder rope and a top beam, wherein the plurality of phase material louver blades are suspended under the top beam through the ladder rope, the bottom beam is suspended at the lowest end of the lowest phase change material louver blade through the ladder rope, certain gap intervals are arranged among the phase change material louver blades to bring convenience to adjusting inclined angles and light transmittance of the phase change material louver blades, the phase change material louver can be collected up or put down by pulling the louver lifting rope, the phase change material louver blades are prepared from graphene and a phase change material through a micro-nano laminating technology, the graphene and the phase change material are evenly arranged in a laminated mode, and the surface is wrapped by a thin high-polymer protection layer. The louver disclosed by the invention has a traditional light shielding function, stores light energy at the same time, can release heat in necessary, can adjust indoor temperature to reduce use of an air conditioner and achieves effects of saving energy and reducing emission.

Description

technical field [0001] The invention relates to a phase change energy-saving technology, in particular to a graphene micro-nano laminated phase-change material energy-saving technology. Background technique [0002] Since the oil crisis in the 1970s, thermal energy storage technology has received increasing attention in the fields of industrial energy conservation and new energy utilization. Phase change materials have the advantages of high latent heat storage density, near adiabatic heat storage and release process, and small heat transfer temperature difference. The application of phase change materials to building materials can alleviate the contradiction between the energy supply and demand of buildings in terms of time and intensity, and play a role in peak-shaving and valley-filling of building heating and air-conditioning loads. The combination of phase change materials and building materials can not only reduce the scale of cold and heat sources, save initial invest...
