An electronic module and chassis/module installation are disclosed. The installation comprises a chassis including a metallic heat input region. An electronic module including an electronic component is adapted to be connected to the chassis. An uninterrupted thermal pathway thermally connects the electronic component of the module to the heat input region of the chassis. The thermal pathway comprises a chimney, a heat channel thermally connected to the chimney, and a heat output block thermally connected to the heat channel. A first electrically insulative non-metallic layer thermally couples the chimney to the electronic component. A second electrically insulative non-metallic layer thermally couples the heat output block to the chassis heat input region.
