    • A method for creating a surface (13,20) having a fast changing temperature, comprises providing a heat exchanger (2) coupled to an orifice (3) opening into a jacket (4) which is in contact with the surface (13,20) to be heated and cooled, the said jacket (4) forming a reservoir capable of housing a fluid in contact with the surface (13,20) to be heated and cooled, and providing two gas sources, each gas source being independently connected to the said heat exchanger (2), one source providing a first gas, which liquefies when it expands through the said orifice (3), and the other gas source providing a second gas, having an inversion temperature lower than the temperature obtained by the liquefaction of the first gas, and causing the exhaust gas flowing out from the said jacket (4), to flow through the said heat-exchanger (2) to preheat or precool the inflowing gas, as the case may be, and further causing the said first and the said second gas alternately to flow through the said heat exchanger (2) and orifice (3), to cool or to heat the said surface (13,20); means (10,11) being provided for allowing and stopping the flow of each gas through the said orifice (3).
    • 一种用于创建表面具有几乎改变温度,方法包括提供在孔口开口联接到热交换器流入夹套的所有这是在与表面接触,以进行加热和冷却时,所述护套形成的贮存器能够容纳在流体中的 与该表面接触,以进行加热和冷却,并提供两个气体源,每个燃气源是unabhängig连接到所述热交换器,一个源提供第一气体,该气体液化当其膨胀穿过所述孔,而另一个气体源 提供一第二气体,具有转化温度比由所述第一气体的液化获得的温度下,以及使从所述护套流出,流过所述热交换器以预热或预冷流入的气体的排气, 视情况而定,并且第一进一步使所述说和第二气体。所述可替换地通过热交换器和所述孔口流动,以冷却或加热。所述面传热 Ë; 装置被提供用于允许和通过孔口所述止动各气体的流动。
