Abstract:
1. A heat dissipation device of electronic circuit modules, comprising: a substrate having a heat dissipation element having a plurality of heat conductors contacted with the at least one transfer contact pad and taking an uneven form, and mounted on a surface of the substrate having the at least one transfer contact pads; and a housing being hollow, and having two openings formed on two sides thereof, a front cover and a rear cover respectively mounted to the two openings, and an airflow passage formed therein; wherein the substrate is mounted inside the housing, the at least one external contact pad penetrates through the front cover and is exposed beyond the housing, heat generated when the at least one electronic component is operated is conducted to the plurality of heat conductors through the at least one transfer contact pad and is guided out of the at least one electronic component by heat convection generated inside the housing by the airflow passage.
