Abstract

Vacuum insulated glass is a key component of green energy-saving buildings. At present, traditional vacuum glass （VG） has many problems, such as edge heat leakage, high cost of indium alloy edge bonding, poor environmental adaptability of rigid structure and so on, which makes it unable to be widely promoted in today's construction industry. Based on Fourier's law, polycarbonate cross laminated vacuum glass （CLVG） is designed in this paper, and its heat transfer and strength are simulated. The results show that at the size of less than 30 cm×30 cm, the cross laminated structure, as a flexible film structure, has a lower heat transfer coefficient than that of VG. Because CLVG has the advantages of low heat transfer coefficient in small size, low cost, light and thin, flexible and convenient transformation, which has broad prospects in the transformation of architectural glass in the future.
