Description

technical field [0001] The invention relates to a temperature measurement technology of a thin film laminator, in particular to a multi-point temperature control system and method for a flexible thin film solar cell module encapsulation laminator. Background technique [0002] At present, the laminator on the market is mainly designed for the packaging of crystalline silicon solar cell components. If the multi-point temperature measurement technology is used, it can provide multi-point temperature parameters, but it cannot control the overall temperature change; and the single-point temperature control technology, Although the temperature change can be controlled, it cannot guarantee the uniformity of the heating plate temperature. [0003] Chinese patent application 201110026884.4 discloses a fully automatic lamination electromechanical heating system for solar cell modules, which includes a body, the body includes a heating plate, uniformly distributed pipes are arranged o...

Problems solved by technology

However, the U-shaped electric heating tube and the heating plate conduct heat between solid and solid, and the heat transfer effect is greatly affected by the contact between the two, which leads to poor temperature uniformity on the surface of the heating plate, especially when the laminator is rigid. When starting up, the surface temperature of the U-shaped heating tube is much higher than the temperature of the heating plate, and the temperature gradient is large and uneven, resulting in uneven thermal expansion, which is likely to cause damage to the electric heating tube and deformation of the heating plate
