這篇稿子是知乎的朋友Ryan Woo給我發(fā)過(guò)來(lái)的，是David Tracy寫的文章《The Tesla Model 3 'Superbottle' Easter Egg Is a Fascinating Packaging Solution》。

1）Super Bottle

這是一個(gè)總成，在Model 3的Parts里面爆炸圖如下：

這是個(gè)集成的裝置，把冷水機(jī)、電動(dòng)的閥、泵和冷卻液罐整合在一起了。

2）蒙羅做的冷卻系統(tǒng)的框圖

這是Munro做的系統(tǒng)框圖，分為冷卻、加熱。在這個(gè)框圖里面包含Chiller和CR兩個(gè)部分。這個(gè)Super Bottle上面的兩個(gè)泵，一個(gè)管電池，一個(gè)管電力電子系統(tǒng)。

1）冷卻

在冷卻模式下，這個(gè)Super Bottle分成兩個(gè)回路，分別進(jìn)行控制。

2）加熱

在加熱模式下，電池和功率電子的回路串聯(lián)在一起，并旁路主的散熱器，使得熱量集聚。當(dāng)電池需要加熱的時(shí)候，冷卻液被泵送到后方的管理模塊，進(jìn)入驅(qū)動(dòng)單元中的油冷卻熱交換器以獲取熱量，通過(guò)集成閥從散熱器轉(zhuǎn)移并直接通過(guò)冷卻器來(lái)加熱電池。特斯拉實(shí)際上利用電機(jī)堵轉(zhuǎn)產(chǎn)生大量的熱量來(lái)加熱電池，可以省卻一個(gè)水熱加熱器。

備注：中秋節(jié)的時(shí)候，一位朋友說(shuō)他是這個(gè)發(fā)明專利的第一作者

這是蒙羅關(guān)于這個(gè)Super Bottle的好處描述：

Increased modularity & packaging space due to the integration of pumps, actuators, and valves with the housing. (Components generally have space protection requirements, separating them could inflate those requirements depending on layout)

Potential for increased serviceability as functional aspects of the cooling system on collocated

Potential weight savings associated with portions of those components housing being integrated with Super Bottle. (Separate clamshell housing with standalone/off the self-pumps for a system with comparable functionality and functional requirements)

Potential weight savings associated with lack separate pumps mounting brackets.

Reduced final assembly costs, as that likely comes in as a complete module.

Reduced final assembly time/labor due to component integration & use of quick disconnects is an assembly process enabler.

小結(jié)：一個(gè)車還是很復(fù)雜的，在細(xì)節(jié)上面一點(diǎn)點(diǎn)進(jìn)步是需要很多工程師的努力的結(jié)果，集成化的趨勢(shì)是體現(xiàn)在很多地方的
