Abstract
描述了用於監測例如浸入式冷卻系統中的篩檢程式的系統及方法。在一個實施例中，本發明涉及一種技術，該技術包括使用過濾介質來過濾流體，其中一種或多種電氣特性根據過濾流體的pH值而變化。可以測量一種或多種電氣特性以監測篩檢程式。如果需要，可以基於篩檢程式的配置修改過濾介質的電氣特性，以便於測量。
Description
本發明涉及用於監測過濾材料的過程及系統，該過濾材料用於例如高速電腦元件的液體浸入式冷卻。
鹵代烴，諸如全氟碳液體介電流體（諸如NOVEC™），經常被用於電腦元件（諸如伺服器）的浸入式冷卻。不幸的是，在所採用的條件下，鹵代烴可能會降解為其它物質，諸如酸、鹼等。這些其它物質可能對電腦元件及/或所採用的系統的其它方面有害。因此，可以使用包括例如氧化鋁及/或其它親水性化學品及混合物的篩檢程式來過濾其它物質。
瞭解其它物質的存在何時變得潛在有害及/或瞭解過濾材料何時接近其使用壽命的終點通常涉及對篩檢程式的視覺監測。例如，如美國專利號5,507,941中所述，可在篩檢程式上或附近使用pH顏色變化指示劑。不幸的是，這些當前的視覺化的監測方法有時不可靠及/或難以實施，尤其是在可能需要攝影機進行視覺化的封閉系統中。因此，需要的是高效且有效的新監測方法及系統。
有利的是，本發明涉及新的監測方法及系統。在一個實施例中，本發明涉及一種過程，該過程包括使用過濾介質來過濾流體，其中一種或多種電氣特性根據過濾流體的pH值而變化。可以測量一種或多種電氣特性以監測篩檢程式。如果需要，可以基於篩檢程式的配置修改過濾介質的電氣特性，以便於測量。
當結合所附申請專利範圍閱讀本發明的示例性實施例的以下詳細描述時，本發明的示例性實施例的這些及其它目的、特徵及優點將變得顯而易見。
以下對實施例的描述提供了參考數位的非限制性代表性示例，以具體描述本發明的不同方面的特徵及教導。所描述的實施例應該被認為從實施例的描述中能夠單獨實施或與其它實施例組合實施。審查實施例的描述的所屬技術領域中具有通常知識者應該能夠學習及理解本發明的不同描述方面。實施例的描述應該有助於對本發明的理解到這樣的程度，使得未具體涵蓋但在閱讀了實施例的描述的所屬技術領域中具有通常知識者的知識範圍內的其它實施方式將被理解為與本發明的應用一致。
本說明書公開的系統及方法通常涉及用於監測例如浸入式冷卻系統中的篩檢程式的系統及方法。在一個實施例中，本發明涉及監測過濾材料的一種或多種電氣特性以檢測介電流體（例如鹵代烴）的化學變化。例如，如果使用氧化鋁或相關材料作為過濾材料，那麼當氧化鋁中和介電流體中的潛在有害物質時，氧化鋁的電阻發生變化。
氧化鋁通常具有非常高的電阻。因此，使用市售的高電阻表是測量電阻並因此有效監測篩檢程式的一種方法。
在另一實施例中，已經發現基於氧化鋁的電阻來有效地監測篩檢程式，然後以方便的方式降低其電阻，以使其可以通過小電流，這可能是有用的。
通過將材料的電阻率乘以材料的長度及橫截面的面積來計算物質的電阻。
公式1：計算電阻的公式。
=電阻率， L=長度， A=橫截面面積。
因此，通常短的長度及大的面積會降低電阻。如圖1所示，兩個塗有氧化鋁的導電屏被配置為大面積及短長度。此外，如圖2所示，將許多屏堆疊在一起，它們中間有氧化鋁，然後以並聯配置對屏進行電氣佈線，這將進一步降低電阻。上述堆疊並聯配置可以連接電阻測量系統。例如，堆疊並聯配置可以連接到電阻測量系統（諸如惠斯通電橋）的一個或兩個支路。氧化鋁的微小變化將顯示為電壓的巨大變化。這種電壓變化可以通過電腦的數位輸入很容易地讀取。在一個具體實施例中，過濾材料的堆疊可以被放置在具有入口及出口的外殼中。其然後可以被放置在常規篩檢程式的線上或用作現有篩檢程式的替代品。
在另一具體實施例中，本發明涉及添加化學試劑或對過濾介質（諸如氧化鋁）進行物理改性，以便更容易檢測變化。這種化學試劑及物理改性可以根據系統、介電流體及過濾介質而廣泛變化。在一個具體實施例中，可以將一塊薄的導電材料（諸如銅）放置在氧化鋁上或內部。如果需要，諸如銅的導電材料可以通過化學反應或以其它方式熔合到氧化鋁上。以這種方式，可以促進電阻率測量以指示變化，並更有效地監測過濾介質。
有利地，使用本說明書描述的系統及方法，可以產生易於被電腦讀取的電壓。其可靠性及可重複性可能會達到甚至超過彩色攝影機的可靠性及重複性，例如，經過校準以區分pH指示劑的粉色及白色之間的差異。因此，如果介電流體中發生降解事件，則可以實施冷卻浸入式設備的更可靠的緊急關閉。
在前述說明書中，已經參照圖式描述了各種實施例。然而，顯然可以對其進行各種修改及改變，並且可以實施附加的實施例，而不背離如所附申請專利範圍中闡述的本發明的更廣泛範圍。因此，說明書及圖式被認為是說明性的而不是限制性的。
本發明與TMGCore，LLC擁有的2019年11月11日提交的標題為「Liquid Immersion Cooling Platform」的PCT公佈文本WO2020/102090有關，該申請通過引用併入本說明書。
無
通過參考以下結合圖式的描述，可以最好地理解本發明的各種實施例連同進一步的目的及優點。
〔圖1〕示出夾在兩個銅屏之間並連接到惠斯通電橋的氧化鋁。該屏允許鹵代烴液體的流動增加或最大化用於中和由分解液體形成的酸或鹼的表面積。
〔圖2〕示出連接交替堆疊的導電屏以使用四個屏形成並聯電網的方法。通常，使用的屏越多，電阻越低。
