Description

具有均热能力的电池模块
技术领域
本实用新型为提供一种具有均热能力的电池模块，尤其是涉及一种具有均热能力的电池模块。
背景技术
当使用由复数个电池组成的电池组时，每一电池会因为放电而升温，然而，每一电池的放电及升温的情况皆不相同，且由于复数电池紧密的排列一起，每一电池的升温情况会与其周围的电池相互影响。
若是其中有电池的升温情况较高，则会导致其与周围的电池温度上升，使得电池组中的部分温度过高。这会使得电池组中的温度分布不平均，容易导致其中的部分电池因着过热而带同其周边的电池过热，进而造成电池组损坏。且若是电池组中的温度分布不均，电池组中温度较高的地方会需要更多时间进行散热，如此会降低电池组整体的散热效率。
因此，有必要提供一种具有均热能力的电池模块，使得电池组中的温度分布平均，以避免部分电池因着过热而造成电池组损坏。
发明内容
本实用新型的目的在于提供一种具有均热能力的电池模块，尤其是涉及一种具有均热能力的电池模块。

作为进一步的改进，复数所述电池呈蜂巢式交错排列而设，所述均热件中的复数所述固定槽呈蜂巢式交错而设。
作为进一步的改进，所述均热件的外壁呈波浪状。
作为进一步的改进，所述均热件的材质为一种液态硅胶材料。
作为进一步的改进，还具有一外壳，所述电池组中还具有一框架，复数所述电池装设于所述框架中，且每一所述电池的正负极皆向外露出于所述框架，所述电池组中还设有至少一导热件，至少一所述导热件贴设于所述框架的外表面上，并与露出于所述框架之每一所述电池的正极或负极相接触，所述导热件的另一侧与所述外壳相接触。
作为进一步的改进，所述外壳的材质为铝。
作为进一步的改进，所述导热件的材质为一种液态硅胶材料。
作为进一步的改进，当设有复数所述电池组时，每一所述电池组之间皆设有至少一所述导热件。复数所述电池组的外表面另贴设有至少一导热件，并与露出于所述框架之每一所述电池的正极或负极相接触。每一所述导热件皆与所述外壳相接触。
如上所述，本实用新型具有均热能力的电池模块能藉由所设置的均热件将电池组中每一电池的均化，如此能使得电池组中的温度分布平均，以避免部分电池因着过热而造成电池组损坏。

具体实施方式
为详细说明本实用新型的技术内容、构造特征、所实现的目的和功效，以下结合具体实施例并配合附图予以详细说明。
请参阅图1及图2，本实用新型公开一种具有均热能力的电池模块100包括有至少一电池组1及外壳2。电池组1设于外壳2中。电池组1包括有复数电池11及一框架12，复数电池11装设于框架12中。复数电池11在框架12中呈蜂巢式交错排列而设，且每一电池11的正负极皆向外露出于框架12。框架12的材质为塑料。外壳2包覆框架12，外壳2的材质为一种金属，具体地，外壳2的材质为铝。
请参阅图3至图6，电池组1中还设有至少一均热件3及至少一导热件4。均热件3套设于复数电池11上，均热件3中开设有复数固定槽31，复数固定槽31呈蜂巢式交错而设。均热件3的外壁32呈波浪状。因着电池11均为圆筒状，故波浪状的外壁32能增加与圆筒状电池11外表面的接触面积，以提热传导的效果。均热件3的固定槽31仅套设于电池组1中较中心部分的复数电池11上，复数电池11中最外围的电池11皆贴设于均热件3的外壁32上。至少一导热件4贴设于框架12的外表面上，并与露出于框架12之每一电池11的正极或负极相接触，导热件4的另一侧与外壳2相接触。均热件3及导热件4的材质皆为一种液态硅胶材料。
均热件3及导热件为使用LSR液态硅胶(Liquid Silicone Rubber)射出成型的方式成型。液态硅胶为一种无毒、耐高温、高回弹性的软质性热固性材料，分子组成中同时具有无机与有机分子结构的独特性软质弹性体材料，其流变型为主要表现为低黏度、高流动性、快速固化、剪切稀化以及较高的热膨胀系数。可以藉由射出成型的方式进行量产。产品表现为良好的耐高温与耐低温特性，热安定性良好，极佳的电器绝缘性与机械性能，优越的耐化性，耐磨耗性、耐臭氧性，卓越的色彩稳定性，能够阻水形成防水密封，具防火阻燃性且燃烧时不会产生有毒的物质，极其洁净，无杂质以及任何潜在的生物污染物，符合医疗和食品级别等。
请参阅图2及图6，当本实用新型具有均热能力的电池模块100中设有复数电池组1时，每一电池组1之间皆设有至少一导热件4。复数电池组1的外表面另贴设有至少一导热件4，并与露出于框架12之每一电池11的正极或负极相接触。每一导热件4皆与外壳相接触。
当本实用新型具有均热能力的电池模块100运作时，复数电池11会持续升温，由于每一电池11的升温情形不同，故每一电池11所上升的温度会传到均热件3上，均热件3会将每一电池11所上升的温度均匀化，使得每一电池11的升温情形趋近一致，进而使电池组1中的温度分布均匀化，以避免出现电池组1中部分区域的温度较高的状况。每一电池11所上升的温度同时传导至设置于框架12外并与每一电池11的正极或负极相接触的导热件4，导热件4再将热传导至外壳2中，由于外壳为金属材质，具有良好的散热性质，如此能对电池组1进行散热，进而避免电池组1温度过高导致损坏。
承上所述，本实用新型具有均热能力的电池模块100能藉由所设置的均热件3将电池组1中每一电池11的均化，如此能使得电池组1中的温度分布平均，以避免部分电池11因着过热而造成电池组1损坏。
