Abstract

本发明提供一种突跳式温控器，其特征在于温控器的双金属圆片一面是89～96wt％铝，1wt％银，其余为镁的铝合金，一面是70～85wt％的钛，7～11wt％锌其余为锆的钛合金，这样铝合金的一面在200摄氏度整体膨胀系数大于20，而钛合金一面膨胀系数小于10，这样金属圆片的灵敏性很高，而且由于是合金材料，耐腐蚀性能很高，可靠性强，广泛应用于温控范围在-50～300摄氏度的电器产品。

Description

一种突跳式温控器
技术领域
本发明涉及温控器，尤其是突跳式温控器。
背景技术
突跳式温控器是一种将定温后的双金属圆片作为热敏感反应组件，当产品主件温度增高或降低时所产生的热量传递到双金属圆片上，达到动作温度设定时迅速动作，通过机构作用使触点断开或闭合，达到接通或断开电路的目的，从而控制电路。双金属材料的碟形片作为感受温度的元件(利用封盖传递热量)在温度上升(或下降)到动作温度时，在瞬间产生突跳动作，该动作被陶瓷的动作杆传递到弹性零件——动触点支架。动触点和定触点分别铆接在动触点支架和牛角上，动触点支架被动作杆推动后，动触和定触点分离，从而使电路断开。当温度下降到碟形双金属片回复温度时，双金属瞬间恢复原来的形状，施在动作杆上的压力消除，动、定触点恢复接通。
但很多单一的金属片，抗腐蚀能力弱，这样影响使用寿命，从而整体影响整个设备的可靠性和寿命。
发明内容
本发明一种寿命长的突跳式温控器。
技术方案如下：
一种突跳式温控器，其特征在于温控器的双金属圆片一面是89～96wt％铝，1wt％银，其余为镁的铝合金，一面是70～85wt％的钛，7～11wt％锌，其余为锆的钛合金。
由此可以产生以下进步效果：铝合金的一面在200摄氏度整体膨胀系数大于20，而钛合金一面膨胀系数小于10，这样金属圆片的灵敏性很高，而且由于是合金材料，耐腐蚀性能很高，可靠性强。
具体实施方式
在具体实施中，首先钛铝，锌，锆按照比例在惰性气体下融化，然后浇注，热轧为2mm一下的薄板，然后将铝，银，镁合金上面浇注2mm，冷却裁片即可得到本发明的双金属圆片。
优化方案一，铝合金中的铝含量为92～94wt％。
优化方案一，钛合金中的铝含量为75～80wt％。
本发明的温控器可广泛应用于温控范围在-50～300摄氏度的电器产品。
