申請(qǐng)?zhí)枮閷?shí)用新型名稱為一種機(jī)柜散熱系統(tǒng),公開了一種機(jī)柜散熱系統(tǒng),包括位于機(jī)柜背面的至少一個(gè)風(fēng)扇組成的風(fēng)扇墻和至少一個(gè)位于所述機(jī)柜上的溫度傳感器,所述風(fēng)扇墻通過至少一個(gè)風(fēng)扇背板與機(jī)柜的機(jī)柜管理控制器相連,所述機(jī)柜管理控制器直接與所述溫度傳感器相連或通過主板管理控制器與所述溫度傳感器相連,所述機(jī)柜管理控制器獲取所述溫度傳感器采集的溫度,并根據(jù)所述溫度控制風(fēng)扇背板輸出控制信號(hào)控制所述風(fēng)扇墻中風(fēng)扇運(yùn)行,該散熱系統(tǒng)解決了現(xiàn)有技術(shù)需要獨(dú)立散熱的缺陷。但是這種設(shè)計(jì)的散熱系統(tǒng)存在局限性,首先該散熱系統(tǒng)必須依靠一種固定的機(jī)柜管理控制器或是主板控制器,通過專門的數(shù)據(jù)傳輸線路來完成數(shù)據(jù)的采集。所使用的設(shè)備通用性較差。用戶必須獲取專門的機(jī)柜管理控制器和數(shù)據(jù)傳輸線路,增加了用戶的經(jīng)濟(jì)成本。
