Among all of the cooling technologies, the impingement cooling is the most potential one to enhance local heat transfer coefficient. The impingement of the jet forms high speed airflows on the cooled surface. These airflows can be used to improve local heat-transfer conditions significantly especially in the area with very high heat flux and temperature.

The results show that the precooling time of the probe is shortened significantly with the help of the vapor liquid separator, and decreases with the driven pressure. With the helical coiled wire and the helical mesh, significant thermal Oscillation corresponding the density-wave is observed in the precooling time. The average heat transfer coefficient enhances 1.5 times with the mentioned heat transfer enhancement techniques, and the temperature of the 2.5 min cryoprobe surface can reach -160℃ in 17℃ brine within 10 min.
