热管具有传热系数高、传热温差小及单向传热等诸多优良特性。以热管为集热部件，试制了一种平板式热管太阳能空气集热器。测试结果表明，在日总太阳辐射为14.4MJ/m2～19.8MJ/m2的气候条件下，平板式热管太阳能空气集热器的瞬时集热效率在15.3%～74.5%之间，集热器出口空气温度可达79.1℃，其日平均集热效率约为32.6%～53.5%，其热损失系数约为3.6～8.4W/(m2·K)。与常规的太阳能空气集热器相比，平板式热管太阳能空气集热器具有较高的集热效率和较低的热损失系数，并且供热温度较高。

Heat pipe has many advantages, such as higher heat transfer coefficient, lower transfer temperature-difference and a one-way heat transfer. A new flat plate heat pipe solar air collector was designed and built based on a reasonable construction. The test results indicated that the instantaneous efficiency of collector is 15.3%~74.5% under the climatic conditions of daily solar radiation being about 14.4 to19.8MJ/m2?day. Its daily average thermal efficiency is about 32.6%~53.5%with heat loss coefficient being 3.6~8.4W/(m2·K). The maximum outlet air temperature can reach 79.1℃. Compared with conventional air collectors, the new flat plate heat pipe solar air collector has higher thermal efficiency and outlet air.
