值得一提的是，本申请将内循环通道划分为三个区域通道，分别为区域通道一13、区域通道二14和区域通道三15；内循环通道的一端设有导通罩2，导通罩2将区域通道二14的一端和区域通道三15的一端连通；内循环通道的另一端设有选择机构和遮挡罩3；选择机构位于遮挡罩3内，用于控制区域通道一13的另一端和区域通道二14的另一端连通或不连通；
遮挡罩3的一端与区域通道一13、区域通道二14和区域通道三15的另一端连通，遮挡罩3的另一端设有内循环出风口31；区域通道一13的一端为内循环进风口16,遮挡罩3用于将换热芯体1的内循环出风导向至从内循环出风口31排出。
需要注意的是，本申请所说的“连通”是指相连通的两端相互对接，空气 从一端进入至另一端，并不会从其余地方排出。
在实际应用中，区域通道一13、区域通道二14和区域通道三15按照自上向下、自左向右或自右向左的方式依次进行划分，当然也可以采用随机的方式进行划分，本申请为了便于操作，将区域通道一13、区域通道二14和区域通道三15按照自上向下的方式进行划分；并将导通罩2通过固定连接或可拆卸连接的方式连接在芯体本体1上；
使用时，根据所需制冷效果，当需要较低制冷效果时，具体参见图1所示，由选择机构控制区域通道一13的另一端和区域通道二14的另一端不连通，此时，区域通道一13的出风口是直接从内循环出风口31排出，具体流向如图1中从内循环进风口16朝向内循环出风口31的箭头所示；
当需要较高制冷效果时，具体参见图2，由选择机构控制区域通道一13的另一端和区域通道二14的另一端连通，此时，区域通道一13的出风口，依次经过区域通道二14和区域通道三15，最后从内循环出风口31排出，具体流向如图2中呈S形的箭头方向所示；
也就是说，可通过调节内循环空气在换热芯体内的行程，调节换热芯体组件的制冷效果，且能充分利用外部冷空气，节约电能。
进一步的，选择机构包括伸缩部件41和选择罩42；伸缩部件41连接在遮挡罩3内，且伸缩部件41的伸缩端与选择罩42连接；选择罩42与区域通道一13的另一端和区域通道二14的另一端对应设置。
由伸缩部件41带动选择罩42伸缩动作，从而实现当选择罩42与芯体本体1接触时，将区域通道一13的另一端和区域通道二14的另一端连通；当选择罩42与芯体本体1不接触时，将区域通道一13的另一端和区域通道二14的另一端不连通；其中，选择罩42为一侧开口的框体，该开口与芯体本体1相对设置；具体参见图3，为了使循环空气平滑流动，在框体的内部底面两端分别设有导向圆角421；为了增加密封性能，在框体靠近芯体本体1一侧设有密封圈422。
本申请的导通罩2和选择罩42的结构相同；伸缩部件41可采用电缸或气缸。
具体参见图4，基于相同的发明构思，本申请还提供了一种间接蒸发冷却机组，第一种实施方式：包括上述的换热芯体组件、内循环风机组件5和外循环风机组件6；内循环风机组件5设置在内循环出风口31处，从而带动内循环空 气进行循环；外循环风机组件6设置在外循环出风口12处，从而带动外循环空气进行循环。
第二种实施方式：在第一种实施方式上增加喷淋组件；喷淋组件包括蓄水池71、水泵72和喷淋头73；蓄水池71的出水口通过管路连接有水泵72和喷淋头73，水泵72用于从蓄水池71内抽取制冷液，以使制冷液从喷淋头73喷出至芯体本体1上；水泵72的流量可调节。
其中，水泵72的流量调节可采用多种方式，一、变速调节：改变水泵的转速，可以使水泵的性能发生变化，从而使水泵的工况点发生变化，这种方法称为变速调解；二、变径调节：叶轮经过车削以后，水泵的性能将按照一定的规律发生变化，从而使水泵的工况点发生改变，我们把车削叶轮改变水泵工况点的方法，称为变径调节；三、节流调节：对于出水管路安装闸阀的水泵装置来说，把闸阀关小时，在管路中增加了局部阻力，则管路特性曲线变陡，其工况点就沿着水泵的Q-H曲线向左上方移动。闸阀关得越小，增加的阻力越大，流量就变得越小，这种通过关小闸阀来改变水泵工况点的方法，称为节流调节或变阀调节；在本申请中，为了实现节能的效果，优选采用对水泵采用变速调节，从而降低能耗。
进一步的，喷淋头73具体有两个，分别与外循环出风口12和外循环进风口11对应设置；蓄水池71位于芯体本体1的下方。
第三种实施方式：在第一种实施方式或第二种实施方式上增加机械制冷组件；机械制冷组件包括压缩机81、冷凝器82、膨胀阀83和蒸发器84；压缩机81、冷凝器82、膨胀阀83和蒸发器84依次通过另一管路串联构成一循环回路；蒸发器84位于内循环风机组件5和内循环出风口31之间，其中，压缩机81的制冷量可调节。运行原理：冷媒在压缩机81的压缩排出后，进入冷凝器82冷凝，然后经过膨胀阀83的限流下，冷媒进入蒸发器84蒸发吸收内循环出气口31排出空气中的热量，进行循环机械制冷；其中，对于压缩机81的制冷量可调节的方式，本申请可以采用所需制冷区域内的温度控制器直接控制压缩机的停开，从而实现温度控制，也可以采用变频式压缩机，通过频率调节，调节机械制冷的制冷量。
值得一提的是，冷凝器82位于外循环出风口12和外循环风机组件6之间，利用外循环空气给冷凝器降温，实现一个风机组件双用途。
本申请一种间接蒸发冷却机组，在使用时，当需要调节温度时，可根据实 际情况可以调节喷淋组件的喷淋量、机械制冷组件的制冷量和内循环空气在换热芯体内的行程，可以进行择一选择或多个选择进行调节；在启用时，对于喷淋组件和机械制冷组件，可以选择择一启动，或两个同时启动。
由此可见，本申请提供的技术方案，可以通过伸缩部件带动选择罩进行伸缩，从而控制区域通道一的出风口是直接从内循环出风口排出，或者，从区域通道二和区域通道三内进行环绕，再从内循环出风口排出，从而可调节内循环空气在换热芯体内的行程，调节换热芯体组件的制冷效果，且能充分利用外部冷空气，节约电能；
本申请还将换热芯体组件与喷淋组件和或机械制冷组件进行配合使用，具有多种模式可选择，且使喷淋组件和机械制冷组件均可调节制冷效果，从而实现实时调节制冷效果；同时，将冷凝器设置在外循环出风口与外循环风机组件之间，利用外循环空气给冷凝器降温，一个风机组件双用途。
以上所述仅为本申请的较佳实施例，并不用以限制本申请，凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
