| 9. | The bigger the diameter , the high the heat efficiency , but the weak the temperature increasing ability , length has less effect on the heat efficiency , tilt angle has less effect on the flow field and temperature field while it is larger than 30 degree , vacuum degree and emissivity have great effect on the flow field and temperature field while there is a great temperature difference between the liquid in the tube and the surroundings , the furring has less effect on the heat transfer but should be cleaned up in 3 - 5 years because of poor water quality , the higher the solar flux or the more the temperature difference between the liquid and the surrounding , the more the heat loss and the lower the heat efficiency
分析了各种因素对太阳能真空集热管流场和温度场的影响。直径越大，热效率越高，但升温能力弱；长度对热效率影响不大；倾斜角度大于30后，自然对流已经能够充分进行，考虑以能够吸收到最大太阳辐射为主；真空度和发射率对热效率和温度场影响很大，尤其是在介质温度与环境温度差异比较大时；水垢对传热影响较小但由于水质的问题应该被3 5年清洗一次；太阳辐射强度越大，介质温度与环境温度差异越大，热损失越大，效率越低； 4 |
