[0065] 空温式汽化器是通过吸收外界环境中的热量并传递给低温介质使其汽化的设备。 [0065] carburetor air temperature by absorbing heat in the external environment, and transmitted to the device so that vaporized cryogenic medium. 由于其具备结构简单、运行成本低廉等优点广泛应用于低温液体汽化器。 Because of its simple structure, low operating cost and the like are widely used in low-temperature liquid vaporizer. 由热力学相关知识可知,汽化器管内工作介质的压力在临界压力以上,温度低于临界温度时为液体,高于临界温度时为气体;在临界压力和临界温度以下时,有一相变的气-液两相区,温度高于压力对应的饱和温度时为气体,低于饱和温度时为过冷液体。 As seen from thermodynamic knowledge, the pressure within the vaporizer tube working medium above a critical pressure and a temperature below the critical temperature of the liquid, above the critical temperature of the gas; at critical pressure and critical temperature, has a phase transition of the gas - liquid when the two-phase region, the temperature higher than the saturation temperature corresponding to the pressure of a gas, subcooled liquid is below the saturation temperature. 如果压力高于临界压力,它的换热特点是分为预热段(临界温度以下)和蒸发段(临界温度以上)两个区段,没有两相共存的汽化阶段。 If the pressure above the critical pressure, it is characterized by a heat exchanger into the preheating section (critical temperature) and the evaporating section (above the critical temperature) of the two sections, there is no vaporization stage of a two phase coexist. 因此,介质的压力和温度决定汽化器的设计方案,不同的流态传热特性有很大差别,需分别考虑、计算。 Thus, the pressure and temperature of the medium determines the design of the vaporizer, the heat transfer characteristics of different flow patterns are very different, need to be considered separately calculated.

[0066] 按照热力学第一定律,汽化器的汽化过程中吸收的总热量,有如下关系式: [0066] According to the first law of thermodynamics, the total heat absorbed in vaporization of the vaporizer, there is the following relationship:
