Abstract. A liquid cooling system is improved by application of a heat-accumulating device. The modified cooling system consists of a heat accumulation unit, flash tank, pump that transfers coolant through the cooling channels, and radiator. Design of heat accumulation device is optimized with the use of developed thermal and mathematical models. The coolant temperature and the radius of the phase transition boundary in the melting substance are calculated. The condition under which the heat accumulator restores the absorption capacity is analyzed. Result of calculated design of heat-accumulating unit providing a thermal mode of device with power of 3 kW within 5 minutes is presented as a practical example. Recommendations are formulated for development and operation of thermal battery allowing to choose parameters and calculate the thermal regime of the liquid heat storage cooling system. Heat storage devices, allowing to significantly improve the weight and size characteristics of cooling systems, are regarded as highly effective means of ensuring the thermal regime of devices operating under severe external conditions.
Keywords: thermal regime, liquid cooling system, heat accumulator, phase transition, octadecane, mathematical model, heat balance equation
