柴油發(fā)電機組的水箱是水冷式發(fā)動機的重要部件，作為水冷式發(fā)動機散熱回路的一個重要組成部件，能夠吸收缸體的熱量，防止發(fā)動機過熱.由于水的比熱容較大，吸收缸體的熱量后溫度升高并不是很多，所以發(fā)動機的熱量通過冷卻水這個液體回路，利用水作為載熱體傳導熱，再通過大面積的散熱片以對流的方式散熱，以維持柴油發(fā)電機組發(fā)動機的合適工作溫度。

　　As an important part of the water-cooling engine heat dissipation
loop,generator radiator can absorb the heat of the engine body and prevent the
engine from overheating.Due to the large specific heat capacity of water, the
temperature rise is not much after absorbing the heat of the engine.Therefore,
the heat of the engine passes through the liquid circuit of cooling water, using
water as the carrier to conduct heat, and then through the large-area fin for
convection.So as to dissipate heat to maintain the proper operating temperature
of the diesel generator.
