    摘要:

    為了提高太陽能飼草干燥設(shè)備空氣集熱器對太陽能的吸收集熱效率,，最大限度的利用太陽能,，分析了太陽能空氣集熱器自動跟蹤太陽技術(shù)，比較了被動跟蹤模式和主動跟蹤模式運(yùn)行過程中的優(yōu)缺點(diǎn),。針對太陽能飼草干燥空氣集熱器提出了被動跟蹤模式與主動跟蹤模式相結(jié)合的單軸跟蹤結(jié)構(gòu),，該跟蹤模式結(jié)合了兩種跟蹤模式的優(yōu)點(diǎn)，很好地克服了兩者的不足,。試驗(yàn)表明,，本系統(tǒng)適用于太陽能飼草干燥，轉(zhuǎn)動跟蹤精度高,，工作穩(wěn)定性好,，而且太陽能接收損失小，結(jié)果顯示本系統(tǒng)可使集熱器出口溫度平均提高15℃,，集熱器效率得到提高，達(dá)到太陽能飼草干燥設(shè)備優(yōu)化的目的,。

    Abstract:

    A sun tracking system was developed in order to improve the collection efficiency of solar air collector and receive more solar energy．Several main tracking modes were briefly introduced. The passive tracking mode was likely to be perplexed by weather condition and the active tracking mode could not avoid the cumulative error．A single axe automatic tracking mode which combined active tracking mode and passive tracking mode wais presented．The proposed combined mode overcame the shortcomings of the two modes．Experiments showed that this system works with high precision,，good stability and little loss of solar energy．Automatic tracking system could make the collector outlet temperature increased an average of 15℃, so that the collector efficiency was improved.
