In order to reduce the volume of POS terminal and avoid dust problems, it is already common to apply fanless design to general POS terminals. Hence, CPU Cooling approach has become the biggest issue for all the manufactures. In 2014, He Yi Technology has began developing a variety of possibilities for solving the problem of heat sources and the thermal insulation for block reflux. And, this study has been smoothly resolved. Therefore, He Yi Technology aggressively pursued international patent protection and has obtained a patent certificate from Taiwan, ROC in may 2016.
