Abstract: A device for internal cooling and pressurization of rotary engine, comprising: a mechanical charger, a charger outlet tube, a core cooling intake tube, an engine air intake tube, a first valve, a second valve, and a third valve. The mechanical charger is mounted in a ventilated place. The charger outlet tube is used to dispense air, and the charger outlet tube has two sides, with one side coupled to the mechanical charger. The core cooling intake tube is connected to another side of the charger outlet tube, and is used to dispense air. The engine air intake tube is connected to another side of the charger outlet tube. The device for cooling and pressurization of rotary engine is capable of achieving improved cooling and performance of rotary engine, through switching a plurality of valves, in automatic control manner and/or in remote control manner.

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 amount of gas and can reduce the amount of gas required.

Abstract translation: 微射流气膜生成装置旨在将气体喷射到期望用于冷却或绝热的工件上。 微喷射气体膜产生装置具有形成为直径为5-100μm的喷嘴，以在工件上产生气膜。 当微射流气膜生成装置的喷口的直径小时，由喷嘴产生的微喷射膜不能由于缺乏足够的能量而产生大的涡流，因此可以在长距离喷射之后保持薄膜 以提高冷却和隔热性能。 此外，由于喷嘴的直径小，所以也消耗较少量的气体并且可以减少所需的气体量。
