Description

工频、中高频感应加热线圈
技术领域
本实用新型涉及一种工频、中高频感应加热线圈，属于冶金、铸造行业与热处理行业的设备领域。
背景技术
目前使用的工频、中高频感应炉、感应加热线圈由通水的铜管绕成，运行时需要不间断的通以水温低于25℃的水，以便将由线圈产生的大量热损耗带走。这种技术的产品在使用中存在的缺点是线圈采用通水的办法降温，导体是一大截面空心导体，在工频、中高频应用场合中，其相邻近的大截面导体在磁场相互切割造成的附加损耗远超过其导体电阻损耗，因而现在的工频、中高频感应加热线圈是一种自身损耗高、效率低的产品（产品的效率只有30%左右），而且在使用过程中自身消耗的能量还需要通过大量的冷却水将其带走。不但要白白消耗大量的电能，还要消耗大量的水资源。另外，由于水的存在，在炉子出现漏炉情况时，如铜管破坏后，水与高温的金属溶液或工件相激会生产大的爆炸，其威力不亚于大型炸弹。这个是感应加热技术目前无法解决的一个极大的技术缺点。
发明内容
本实用新型的目的是为了克服已有技术的缺点，提供一种采用多根低附加损耗不通水导线并联导体，大幅降低线圈传递能量过程中本身的损耗，提高线圈能量转换效率，达到减小损耗，无需水冷，节电、相对更安全的工频、中高频感应加热线圈。
本实用新型工频、中高频感应加热线圈的技术方案是：其特征在于包括小截面并联导线、匝内绝缘、匝间绝缘、夹持线圈的上、下夹持件组成工频、中高频感应加热线圈，在线圈与上、下夹持件外部有紧固部件与外覆绝缘。
本实用新型的工频、中高频感应加热线圈，所述的感应加热线圈采用多根小截面低附加损耗导线并联，所述的小截面导线主要指薄片材料或者小直径圆形导线，这些小截面导线在匝内相互绝缘，匝间也用绝缘隔开，以承受其工作电压，从而实现低损耗至不通水也可以实现温度不超过材料允用温度的技术目标。可大幅度地降低其较50赫兹及更高频率运行造成的集肤效应与附加损耗至原大截面空心铜管损耗的1/30至1/300或更大的范围，从而不需采用通水的办法散热，并将带几千伏电压的感应加热线圈全部绝缘起来，从根本上解决产品运行的高损耗、安全性与易用性问题。本技术方案将线圈的温升降低至一个不通水也可以的状态，从而使传统的工频、中高频感应线圈得以极大的改革，给用户的使用以极大的便利与电、水资源的节省。
本实用新型的工频、中高频感应加热线圈，所述的小截面并联导线至少为2根以上，一般是2至3根就可。所述的小截面并联导线为铜箔材料所制成，多根小截面铜箔导线可轴向并联，也能大幅度地降低集肤效应与附加损耗。
