冷凝器通常通过对外界环境进行放热，以降低其内的换热媒介的温度。通 常，降低外界环境的温度以及改善外界环境中流体的流通状况，有利于提高冷凝器的换热效率。如图1-6所示，本具体实施方式涉及一种用于提高冷凝器换热效率的装置，包括装置本体1，所述装置本体1上设置有能够使气流通过、并对通过的气流起到调节作用的调节单元2；
所述调节单元2能够改变流经其内的气流的温度，使气流在流出所述调节单元2时的温度低于气流在流入所述调节单元2时的温度；
和/或，所述调节单元2能够改变流经其内的气流的流速，使气流在流出所述调节单元2时的流速大于气流在流入所述调节单元2时的流速；
由所述调节单元2流出的气流能够与所述冷凝器进行热量交换。温度降低和/或流速增大的气流使所述冷凝器能够处于更佳的换热环境中，有利于提高其换热效率，加快换热速度，并可提高冷凝器的最大换热量。
作为一种较佳的实施方式，所述调节单元2通过节流效应调节流经其内的气流的温度及流速，更具体地，如图3-6所示，所述调节单元2包括进风口21和出风口22，所述进风口21和所述出风口22之间连通设置有气流通道；
所述进风口21的流通面积大于所述出风口22的流通面积，气流以较低的流速和较高的温度由所述进风口21进入所述调节单元2，由于所述出风口22的流通面积变小，气流在流出所述出风口22时发生节流膨胀，温度降低；同时，缩小所述出风口22的流通面积，可使由所述出风口22流出的气流的流速提高。优选地，所述进风口21和所述出风口22均为圆形开口。需要说明的是，此处及后文中所说的“流通面积”，即为能够使气流流过的有效面积。
由所述出风口22流出的气流温度降低，流速增大，使所述冷凝器处于低于实际环境温度、且气流流动较快的换热环境下，可以提高冷凝器的换热效率，即使在环境温度较高时，也可使所述冷凝器保持良好的换热效率。同时，在所需换热量一定的情况下，可选用较小规格的冷凝器和其配套设备，以减小冷凝器工作时所占用的空间以及材料成本，并可降低设备工作噪音。此外，利用节流效应，所述调节单元2无需消耗电能即可达到调节气流温度及流速的目的， 有利于减少具有该冷凝器及所述用于提高冷凝器换热效率的装置的耗电量，降低用户的使用成本，并有利于节能减排，保护环境。

包括所述第一通道23和所述第二通道24的所述气流通道的结构形式规则美观、易于加工，且能够起到良好的节流效果。需要说明的是，所述气流通道的结构形式并不局限于该较佳的实施方式所描述的结构形式，其它可带来节流效果的结构形式均可应用于所述气流通道处。
作为一种较佳的实施方式，所述调节单元2的数量为多个，多个所述调节单元2均匀分布于所述装置本体1上，以增大通过所述装置本体1的气流流量及气流均匀性；多个所述调节单元2的所述出风口22均位于所述装置本体1的相同一侧，以使多个所述出风口22能够共同朝向所述冷凝器设置；同时，多个所述调节单元2的所述进风口21均位于所述装置本体1的相同另一侧，以使多个所述进风口21能够共同朝向外界环境设置，此处所说的“外界环境”，指的是所述装置工作时所处的环境，所述外界环境中的气体能够流动通过所述调节单元2。由多个所述进风口21共同进风，再使气流由多个所述出风口22共同流出，有利于增大进风气流，经过节流作用调节后的气流直接与冷凝器进行换 热，有利于提高冷凝器换热效率。优选地，多个所述调节单元2成多行多列方式排列设置于所述装置本体1上，且相邻所述调节单元2相接设置，相邻两所述调节单元2之间互不连通，以避免不同所述调节单元2内的气流发生互窜，从而提高节流效率。多个所述调节单元相接设置，有利于提高所述装置本体1面积的利用率，增大进风面积，从而增大所述装置本体1的整体气流通量，进一步提高与所述冷凝器进行换热的气流流量，提高所述冷凝器的换热效率。
作为一种较佳的实施方式，如图1-6所示，所述装置本体1为板状结构，所述调节单元2贯穿所述装置本体1的厚度进行设置，使气流能够通过所述调节单元2从所述装置本体1的一侧流动至另一侧，此处所说的“一侧”和“另一侧”，指的是所述装置本体上与其板厚方向相垂直的“一侧”表面和“另一侧”表面。成板状结构设置的所述装置本体1能够包围设置于所述冷凝器的外部，减小所述装置所占据的空间。优选地，所述装置设置为用于对冷凝器进行保护的保护罩，所述保护罩具有防止冷凝器的翅片在运输、安装及使用过程中由于受到外力作用而变形的作用，其能够替代现有的、通常为金属丝网形式的保护罩，起到提高冷凝器换热效率及保护冷凝器的双重作用，有利于增加所述装置的实用性，并进一步减小所述装置所占用的体积。
