如圖1所示,熱失控電池芯111與第一電池芯113位於同一個上散熱通道132內,並與第二電池芯115及第三電池芯117位於不同或相鄰的上散熱通道132內。
As shown in FIG. 1 , the thermal
請配合參閱圖10所示,圖10的九顆電池芯11為圖1虛線內的九顆電池芯11的電路圖,熱失控電池芯111與第一電池芯113及第三電池芯117的正負極設置方向相反,並與第二電池芯115的正負極設置方向相同,其中熱失控電池芯111與第二電池芯115經由導電片17的連接單元173並聯。具體而言,若熱失控電池芯111的正極朝向上方,則第二電池芯115的正極亦朝向上方,而第一電池芯113及第三電池芯117的負極則朝向上方。

在未設置上散熱板13及下散熱板15的情況下,熱失控電池芯111可能會朝相鄰的第一電池芯113、第二電池芯115及第三電池芯117噴出高熱可燃物質163,並會經由熱傳導將熱量傳遞至第一電池芯113、第二電池芯115及第三電池芯117,使得第一電池芯113、第二電池芯115及第三電池芯117的溫度大幅上升。
In the absence of the upper
此外,熱失控電池芯111發生熱失控時會形成短路,使得第二電池芯115經由導電片17的連接單元173向熱失控電池芯111輸出大電流I,導致第二電池芯115的溫度進一步升高,並大幅提高第二電池芯115發生熱失控的機率。具體而言,第二電池芯115受到熱失控電池芯111的影響,而發生熱失控的機率可能會大於第一電池芯113及第三電池芯117。

本新型透過上散熱板13及下散熱板15隔離經由連接單元173並聯的熱失控電池芯111及第二電池芯115,使得經由連接單元173並聯的電池芯11分別位於不同的上散熱通道132及下散熱通道152內,以降低熱失控電池
芯111噴出的高熱可燃物質163傳遞至第二電池芯115,並降低第二電池芯115發生熱失控的機率。
The present invention isolates the thermal
此外,由於熱失控電池芯111及第二電池芯115位於不同的上散熱通道132及下散熱通道152,因此即便熱失控電池芯111及第二電池芯115一起發生熱失控,亦可經由不同的上散熱通道132及/或下散熱通道152分別引導熱失控電池芯111及第二電池芯115噴出的高熱可燃物質163。
In addition, since the thermal
在本新型一實施例中,熱失控電池芯111及第二電池芯115的正極分別位於相鄰的上散熱通道132內,而熱失控電池芯111的正極與第一電池芯113的負極位於同一個上散熱通道132內。
In an embodiment of the present invention, the positive poles of the thermally
一般電池芯11的閥門通常設置在正極,因此熱失控電池芯111會由位於上方的正極噴出高熱可燃物質163,其中大部分的高熱可燃物質163會沿著上散熱通道132擴散,並與同一個上散熱通道132內相鄰的第一電池芯113的負極接觸。
Generally, the valve of the
如圖2所示,當第一電池芯113由相鄰的熱失控電池芯111或噴出的高熱可燃物質163吸收熱量,並造成第一電池芯113發生熱失控時。由於第一電池芯113正極朝向下方,使得熱失控的第一電池芯113會由位於下方的正極噴出高熱可燃物質163,其中大部分的高熱可燃物質163會沿著下散熱通道152擴散。
As shown in FIG. 2 , when the
具體而言,熱失控電池芯111噴出的高熱可燃物質163會噴向上散熱通道132,並經由上散熱通道132引導並傳輸到上散熱通道132或電池設備10的外部。與熱失控電池芯111相鄰的第一電池芯113噴出的高熱可燃物質163則會噴向下散熱通道152,並經由下散熱通道152引導並傳輸到下散熱通
道152或電池設備10的外部。因此,熱失控電池芯111及相鄰的第一電池芯113噴出的高熱可燃物質163,會分別經由不同的散熱通道傳送至外部,可提高熱失控電池芯111及熱失控的第一電池芯113的散熱效果,並避免電池芯11發生熱失控的連鎖反應。
Specifically, the high-heat
此外,熱失控電池芯111的正極雖然與第二電池芯115的正極相鄰,但兩者分別位於不同的上散熱通道132,並被上散熱板13隔離。使得熱失控電池芯111的正極噴出的高熱可燃物質163不會傳遞到相鄰的上散熱通道132及相鄰的第二電池芯115的正極,可避免第二電池芯115的正極溫度過高,而導致第二電池芯115發生熱失控。
In addition, although the positive pole of the thermally
即便第二電池芯115由熱失控電池芯111吸收熱量,導致第二電池芯115發生熱失控。熱失控的第二電池芯115的正極會朝與熱失控電池芯111不同的上散熱通道132噴出高熱可燃物質163,使得熱失控電池芯111及相鄰的第二電池芯115噴出的高熱可燃物質163分別經由不同的上散熱通道132傳遞至外部,以提高散熱的效果。
Even if the
由上述的內容可知,本新型的電池設備10在正常使用的狀況下,可透過上散熱板13及下散熱板15引導冷卻氣流161。冷卻氣流161會沿著上散熱通道132及下散熱通道152流動,並與上散熱通道132及下散熱通道152內的電池芯11接觸,以帶走電池芯11的熱量。
From the above, it can be known that the
當電池設備10內的電池芯11發生熱失控時,上散熱板13及下散熱板15則可用以引導熱失控的電池芯11噴出的高熱可燃物質163,並將高熱可燃物質163引導至外部。此外,當相鄰的電池芯11同時發生熱失控時,由相鄰的電池芯11噴出的高熱可燃物質163,會分別經由不同的上散熱通道132
或不同的下散熱通道152傳輸至電池設備10的外部,有利於將熱失控的電池芯11噴出的高熱可燃物質163經由不同的路徑快速引導至外部,避免高熱可燃物質163長時間累積在電池設備10內,而造成其他電池芯11過熱而發生熱失控的情形。
When thermal runaway occurs in the
在本新型上述實施例中,上散熱通道132及下散熱通道152內僅設置單一排的電池芯11。但在實際應用時,上散熱通道132及下散熱通道152亦可設置複數排的電池芯11,例如兩排的電池芯11,同樣可達到本新型所述的效果。此外,在本新型一實施例中,上散熱板13及下散熱板15之間的夾角亦可為90度。
In the above embodiments of the present invention, only a single row of
以上所述者,僅為本新型之一較佳實施例而已,並非用來限定本新型實施之範圍,即凡依本新型申請專利範圍所述之形狀、構造、特徵及精神所為之均等變化與修飾,均應包括於本新型之申請專利範圍內。 The above is only one of the preferred embodiments of the present invention, and is not intended to limit the scope of implementation of the present invention, that is, any equal changes and changes made according to the shape, structure, characteristics and spirit described in the patent scope of the present application Modifications should be included in the scope of the patent application for the present model.
