参见图3、5和6，矩形环状框构件90被配置来耦合导矩形环状框构件98，以固定其间的电池单元92、紧固环状构件94、和电池单元96。

参见图3、5和6，提供紧固环状构件94进一步紧固矩形环状框构件90、98之间的电池单元92、96。紧固环状构件94的外周尺寸小于矩形环状框构件90的外周尺寸，并且小于矩形环状框构件98的外周尺寸。紧固环状构件94被布置在电池单元92、96的外缘部分之间，以进一步支承电池单元92、96。

参见图7和8，根据耦合在一起以形成内部区域224的板构件220、222来构造外壳202。外壳202包括边缘225、226、227、228。边缘225、226彼此基本上平行，并且彼此间隔开。边缘227、228彼此基本上平行，并且彼此间隔开。
参见图7和9，板构件220、222的部分形成具有入口孔232的入口延伸部分229。入口延伸部分229被配置以使在入口孔232的一部分中容纳入口管204。入口孔232与外壳202的内部区域224以及与冷却歧管78形成流体联通。因此，进入入口管204的流体流过孔232的部分而进入内部区域224内。
参见图7和8，板构件220、222的部分被彼此相向挤压，以在内部区域224内形成导流构件240、242、244、246、248、250、250、252。导流构件240、242、244、246、248、250、250、252限定了通过内部区域224的盘旋流径260。
导流构件240从边缘225总体朝着边缘226延伸，并且相对于外壳100的水平轴300以1-5度范围内的角度向上延伸。导流构件240在构件240和边缘228之间限定流径区域261。
导流构件242从边缘226总体朝着边缘225延伸，并且相对于外壳100的水平轴300以1-5度范围内的角度向上延伸。导流构件242在导流构件242和导流构件240之间限定流径区域262。

导流构件250从边缘226总体朝着边缘225延伸，并且相对于外壳100的水平轴300以1-5度范围内的角度向上延伸。导流构件250在导流构件250和导流构件248之间限定流径区域270。
导流构件252从边缘225总体朝着边缘226延伸，并且相对于外壳100的水平轴300以1-5度范围内的角度向上延伸。导流构件252在导流构件252和导流构件250之间限定流径区域272，并且限定在构件252之上的流径区域274。
参见图7和10，盘旋流径260包括流径区域261、262、264、266、268、270、272、274。当具有气泡的流体流过盘旋路径260时，气泡容易从流径区域261经中间的流径区域而迁移到流径区域274。盘旋流径260流入流径290内。流径290与边缘227基本上平行。流径290具有比盘旋流径260的流径区域261、262、264、266、268、270、272、274的横截面面积更小的横截面面积。因此，从盘旋流径260进入流径290的流体被加速，并且通过流径290来运送在流体中的任何气泡。流径290流入与边缘226基本上平行的流径294。流径294也具有比盘旋流径260的流径区域261、262、264、266、268、270、272、274的横截面面积更小的横截面面积。流径294从流径292延伸至出口孔234。因此，通过流径294向出口孔234运送流体和在流体中的任何气泡。
板构件220、222的部分形成具有出口孔234的出口延伸部分230。出口延伸部分230被配置以使在出口孔234的部分中容纳出口管204。出口孔234与在图1中所示的外壳100的内部区域244和冷却歧管80两者形成流体联通。因此，离开孔224的流体离开所述出口管206，进入冷却歧管80内。

电池单元104被布置在矩形环状框构件106和热交换器100的一部分以及紧固环状框构件102的一部分之间。电池单元104的结构基本上类似于电池单元92。
矩形环状框构件106被配置来耦合到矩形环状框构件98，以保持在其间的热交换器100、紧固环状框构件102、和电池单元104。
具有带盘旋流径的热交换器的电池单元组件相对于其他电池提供了实质优点。具体说，电池单元组件具有带盘旋路径的热交换器，它提供了清除在流过热交换器的流体中的气泡的技术效果，以获得经过热交换器的用于冷却电池单元组件中电池单元的期望的流体流量。
