Heating and heat dissipating multi-layer circuit board structure for keeping operating temperature of electronic components

摘要

A heating and heat dissipating multi-layer circuit board structure for keeping operating temperatures of electronic components is provided. The outer layer of the multi-layer printed circuit board is in contact with electronic components. The operating temperatures of electronic components are measured through by a temperature measuring circuit. When the operating temperature of at least one electronic component is lower than a default temperature, the heating circuits corresponding to the electronic components are enabled respectively to heat the electronic components through corresponding heat conduction elements. When the operating temperature of at least one electronic component is higher than another default temperature, the heating circuits corresponding to the electronic components are disabled to transfer the heat from the electronic components to the heat conduction elements automatically. Therefore, the structure achieves the goal of keeping the operating temperature of each electronic component in the corresponding environment.
