非能动低温空冷器的设计

Analysis for the Heat Exchange Efficiency of Passive Low-Temperature Air-Cooler

摘要: 本文根据我国东北地区存在较长时间低温季节的现状，结合非能动低温自然循环技术，设计了一种非能动低温空气冷却器。建立了数学模型，对模型的传热性能进行了计算分析。分析结果表明，非能动低温空气冷却器能够有效利用寒冷地区的自然冷源，实现制冷设备的低能耗甚至零能耗，达到高效节能环保的目的。

Abstract: As weather is cold during a long period of time in the northeast of China, this paper presents a passive low-temperature air-cooler combining the passive low-temperature natural-circulatory technology. It builds a mathematical model which the heat exchange efficiency of the passive low-temperature air cooler was analyzed. The result indicates that the passive low-temperature air-cooler which makes use of the natural cooling source in the cold area can reduce the consumption of energy or even no consumption of energy. This can not only save a lot of energy but also protect the environment.
