摘要：
The influence of the average velocity of jet of HFE-7100 dielectric liquid on the heat transfer and the critical heat flux was experimentally studied with the use of an array of 36 submerged impinging microjets at a large initial subcooling. The heating surface was cooled in a slot-shaped channel with a gap of 1 mm for a distributed array of microjets with diameter of 174 mu m. With the distributed array of microjets of dielectric liquid with low heat of vaporization and thermal conductivity, at an initial liquid subcooling of 38.2 degrees C relative to the saturation temperature it was possible to obtain a critical heat flux of 237 W/cm(2) at a jet velocity of 9.56 m/s, which corresponds to a heat release source power of 186 W.
