    • A heat exchanger is provided in which high heat transfer efficiency has been attained by optimizing the slit array and setting an optimum range for the width of a slit and the spacing between slits. Slits 51 and 52 formed in front of the heat transfer coil 4 and slits 55 and 56 formed behind the heat transfer coil are arranged so as to provide a mutually different length among adjoining partitioned slits in the vertical direction, as well as a mutually different length between directly opposite partitioned slits in the horizontal direction. As a result, the position at which the slit is partitioned is staggered. The two slits 53 and 54 formed side by side between heat transfer coil 4 and heat transfer coil 4 are of the same length. For a 7 mm diameter heat transfer coil, the slit width relative to the diameter of the heat transfer coil ranges from 1.2/7 (approximately 0.17) to 2.0/7 (approximately 0.29), and the slit spacing relative to the diameter of the heat transfer coil ranges from 1.3/7 (approximately 0.18) to 3.5/7 (approximately 0.5).
    • 提供了一种热交换器,其中通过优化狭缝阵列并设置狭缝宽度和狭缝之间的间距的最佳范围已经实现了高传热效率。 在传热线圈4的前方形成的狭缝51,52和在传热线圈后面形成的狭缝55,56布置成在相邻的分隔开的狭缝之间在垂直方向上提供相互不同的长度,以及相互不同的长度 在水平方向上直接相对的分隔狭缝之间。 结果,狭缝被分隔的位置交错。 在传热线圈4和传热线圈4之间并排形成的两个狭缝53和54具有相同的长度。 对于7mm直径的传热线圈,相对于传热线圈的直径的狭缝宽度范围为1.2 / 7(约0.17)至2.0 / 7(约0.29),并且相对于热的直径的狭缝间隔 传输线圈范围为1.3 / 7(约0.18)至3.5 / 7(约0.5)。
