伺(si)服(fu)驅動(dong)(dong)器(qi)的散(san)熱(re)設計(ji)直接影響(xiang)其長期運行可靠性，常見的散(san)熱(re)方式包括(kuo)自然冷卻(que)(que)(que)、強制風(feng)冷、水(shui)冷等。小功(gong)(gong)率(lv)驅動(dong)(dong)器(qi)（如 1kW 以下）通常采(cai)用自然冷卻(que)(que)(que)，通過(guo)大(da)面積散(san)熱(re)片將熱(re)量傳導(dao)至空氣中；中大(da)功(gong)(gong)率(lv)驅動(dong)(dong)器(qi)（1kW-100kW）多采(cai)用強制風(feng)冷，配(pei)備溫(wen)(wen)(wen)(wen)控(kong)風(feng)扇，在溫(wen)(wen)(wen)(wen)度超過(guo)閾值時(shi)(shi)自動(dong)(dong)啟動(dong)(dong)；超大(da)功(gong)(gong)率(lv)驅動(dong)(dong)器(qi)（100kW 以上）則需(xu)水(shui)冷系統，通過(guo)冷卻(que)(que)(que)液循環帶走熱(re)量，適用于(yu)高環境溫(wen)(wen)(wen)(wen)度或密封柜體場景。散(san)熱(re)設計(ji)需(xu)考慮功(gong)(gong)率(lv)器(qi)件(jian)的結溫(wen)(wen)(wen)(wen)限(xian)制，例如 IGBT 的結溫(wen)(wen)(wen)(wen)通常為 150℃，設計(ji)時(shi)(shi)需(xu)預留(liu)足夠的溫(wen)(wen)(wen)(wen)度余量，避(bi)免熱(re)應力導(dao)致的器(qi)件(jian)失效。云浮大(da)電流輸入伺(si)服(fu)驅動(dong)(dong)器(qi)有(you)哪些禎思(si)科伺(si)服(fu)驅動(dong)(dong)器(qi)集成先(xian)進(jin)技術，簡化設備調試流程。
