Abstract
A micro jet gas film generation apparatus aims to eject a gas to a work object which is desired for cooling or insulating from heat. The micro jet gas film generation apparatus has a spout formed at a diameter of 5-100 μm to generate a gas film on the work object. As the diameter of the spout of the micro jet gas film generation apparatus is small, the micro jet gas film generated from the spout cannot produce a large eddy due to the lack of sufficient energy, hence can maintain a thin film after a long distance ejection to improve cooling and heat insulation performance. Moreover, due to the small diameter of the spout, it also consumes less gas and can reduce the amount of gas required.
