<P>PROBLEM TO BE SOLVED: To provide a technique suppressing energy for warming up a device requiring warm-up at low temperatures, in a system equipped with a device requiring warm-up at low temperatures. <P>SOLUTION: This heat exchanging system is provided with: a warm-up object; a radiator exchanging heat between the outside air and a heat exchange medium; a medium circulation passage circulating the heat exchange medium between the warm-up object and the radiator; a circulation pump arranged in the medium circulation passage for circulating the heat exchange medium; a warm-up object temperature detection part detecting the temperature of the warm-up object; an outside air temperature detection part detecting the outside air; and control part driving the circulation pump at predetermined timing when the outside air temperature is higher than the warm-up object temperature. <P>COPYRIGHT: (C)2008,JPO&INPIT |
