<p>PURPOSE:To prevent the break of a power supply and the disablement of a logic function by carrying out cooling and temperature detection at two stages by providing the cooling system of a logic unit, used for a computer, with 1st and 2nd blowers and 1st and 2nd temperature sensores. CONSTITUTION:This system consists of 1st belowers 1a to 1d which send air from the lower part of logic unit 1, 2nd belowers 2a to 2d for air exhaustion operating when 1st temperature sensors 11a to 11d at outlets detect an exhaustion air temperature of more than (t1) deg.C, and 2nd temperature sensors 21a to 21d provided at the outlets and outputting a signal for cutting off the power supply when the exhaustion air temperature exceeds upper-limit temperature (t2) deg.C where the logic element will never get out of order.</p> |
