Wind cooling accelerated eliminationofheat dissipation, and controlled temperature which made welding transverse contraction deformation and the residual stresses decrease.
气冷的方法，可以使试样散热更快，达到控制温度的目的，同时也可以减小焊接残余应力和焊接横向收缩变形。

The back-light in this invention realizes the fixing of the backboard which needs eliminationofheat and needs big size back-light power and the radiator, and its fixing is simple and convenient.
通过本发明的背光源可以实现需要散热的，大尺寸背板源的背板与散热器的固定安装，并且安装简单方便。
