Description

technical field [0001] The invention relates to a heat storage and temperature control device, in particular to a temperature control device for an oil storage system of a generator set in a polar scientific research station by using the waste heat from the tail gas of a diesel generator set in a polar low temperature environment. Background technique [0002] The energy support of the polar scientific research station mainly comes from the power generation of the generator set. The low temperature characteristics of the polar region will cause the fluidity of diesel oil to decrease, which in turn will lead to the problem of poor oil supply or even flameout of the diesel generator set. Therefore, the effective preheating and uniform temperature of the oil storage in the polar scientific research station is an important measure to ensure the efficient and smooth operation of the generating set in the low temperature and low pressure environment. At present, there are mainly t...

Problems solved by technology

The common feature of the above three methods is that the heat for diesel preheating must come from an independent external heat source. If the above three methods are applied to the preheating of the oil storage of the generator set in the polar scientific research station, the following two problems will appear On the one hand, the polar environment is harsh and there is a serious shortage of directly available energy; on the other hand, the geometric size of the oil storage system of the generator set in the polar scientific research station is much larger than that of the motor vehicle oil storage system, and the thermal conductivity of diesel oil is low. method can lead to the consequences of uneven oil temperature in the oil storage system
