Abstract

Electronic device 11 on occasion increases dangerously high in temperature if the heat flux becomes high or the primary cooling becomes inadequate. Device 11 is mounted on porous plate 13 which caps reservoir 15 of cool fluid 17. When sensor 19 at device 11 exceeds a limit, it starts remotely-located pump 21. The latter causes passages through plate 13 and the cool fluid film 23 to envelop device 11 by the transpiration process.
