发热丝31可以选用钨丝，钨丝具有耐高温，绕制性能好的特点，在其他实施例中，也可以使用其他耐高温材料，如铂铑丝。在保证电压足够的情况下，发热丝31的温度可以达到1500℃以上。
点火器40为电子设备，其通过供电的形式使发热丝31发热，从而引燃放热焊接剂20，第一导线32的长度不限定，具体实施时，引燃放热焊接剂20后可以取出引燃器30，以便再次使用，若发热丝31受损，可以通过更换新的发热丝31以便进行下一次操作。
通过电能转化为热能，以达到放热焊接剂20铝热反应的触发温度，本实施例中放热焊接剂20包括氧化铜和铝单质等，通过氧化还原反应，置换出铜 单质，以达到焊合效果，本实施例中的产品需要铜，因此需要置换出铜单质。具体实施时，可以根据不同的需求，更换不同的反应物质。
具体的，该放热焊接设备100能够通过点火器40供电的形式引燃放热焊接剂20，通过引燃器30和点火器40的配合以提供安全距离，提高了安全系数，且相对于现有技术降低了成本，提高了操作效率。
结合图2-图5，可选的，模具10包括第一模具11和第二模具12，第一模具11具有向内凹陷的第一容纳腔111，第二模具12具有向内凹陷的第二容纳腔121，第一模具11与第二模具12配合时，第一容纳腔111与第二容纳腔121连通且形成容置空间。

可选的，第一模具11还具有与第一容纳腔111连通的第一成型腔112，第二模具12还具有与第二容纳腔121连通的第二成型腔122，第一模具11与第二模具12配合时，第一成型腔112与第二成型腔122连通且形成成型空间。
本实施例中成型空间和容置空间相对独立，安放时，容置空间相对远离地面，成型空间相对靠近地面，放热焊接剂20反应后，铜液在重力的作用下流入成型空间内，对成型空间内需要进行焊合的物质进行焊合。
可选的，第一模具11设置有第一穿设槽113，第一穿设槽113贯穿第一模具11且与第一成型腔112连通，第二模具12设置有第二穿设槽123，第二穿设槽123贯穿第二模具12且与第二成型腔122连通，第一模具11与第二模具12配合时，第一穿设槽113与第二穿设槽123连通且形成穿设孔101，穿设孔101配置成穿设线材201。
结合图6，本实施例中，放热焊接的产品为线材201，其通过穿设孔101，使相应的位置处于成型空间内，铜流入成型空间内冷却后，最终成型为紧固块202。
可选的，模具10还包括盖合模13，盖合模13通过铰链可转动的连接于 第一模具11或第二模具12，盖合模13具10有连通通道131，第一模具11与第二模具12配合且盖合模13盖合第一模具11与第二模具12时，连通通道131令容置空间与盖合模13的外部连通。
本实施例中，盖合模13与第二模具12铰接，通过盖合的形式使放热焊接剂20处于相对封闭的空间内。该连通通道131便于外部的空气进入容置空间内，以提供反应所需的氧气，同时铝热反应产生的热量可以通过该连通通道131进行转移。
可选的，盖合模13设置有连通槽132，连通槽132令容置空间与盖合模13的外部连通，连通槽132配置成穿设第一导线32且使发热丝31位于容置空间内。
使用时，将第一导线32卡设在连通槽132处，然后再实施盖合，使发热丝31处于容置空间内，使第一连接头33处于盖合模13的外部。
可选的，放热焊接剂20呈圆台状，放热焊接剂20的外壳采用铜制成。
本实施例中，容置空间呈圆台状，因此该放热焊接剂20也采用圆台状，放热焊接剂20的外壳采用铜制成，也可以采用铝、钢、防潮纸等，以便反应时，全部反应，材料得到充分的利用。
结合图7-图10，可选的，引燃器30还包括固定头34，固定头34具有卡接空间350，发热丝31的一端卡设于卡接空间350内，第一导线32的一端也卡设于卡接空间350内。
固定头34由于有卡接空间350的存在，使用时，可以将发热丝31和第一导线32卡设在卡接空间350内，两者接触以达到导电的作用。
可选的，固定头34采用导电材质制成。
本实施例中固定头34可以由铁、铜等导电性较佳的材质制成，也就是说，只要将两者卡接，就可以实现导电的作用。
可选的，固定头34内置有导电层，发热丝31的一端与第一导电层接触，第一导线32的一端也与导电层接触。
另一种实施方式下，可以是内置导电层，以达到接触便导电的作用。
该导电层可以由导电性能较佳的材质制成，其可以呈片状，以便更好的贴合固定在固定头34的内表面上。
结合图10，可选的，固定头34包括固定片35，固定片35呈底部开口的矩形框，固定片35包括依次连接的第一部351、第二部352和第三部353，第一部351远离第二部352的一端在靠近第二部352中部的方向上延伸，第三部353远离第二部352的一端在靠近第二部352中部的方向上延伸，第一部351、第二部352和第三部353围合且形成卡接空间350。
安放好后，可以用钳子等装置夹住第一部351和第三部353，使其挤压在第一部351上，使第一部351和第三部353卡紧位于卡接空间350内的第一导线32和发热丝31。
结合图8，可选的，发热丝31包括第一连接部311、发热部312和第二连接部313，第一连接部311与第一导线32的正极端连接，第二连接部313与第一导线32的负极端连接，发热部312的一端与第一连接部311连接，发热部312的另一端与第二连接部313连接，发热部312呈螺旋状。
由于电荷聚集在曲率半径小的地方，而物理连接使得连接处易于产生曲率半径小的连接点造成电能集中，为了避免这种现象，本实施例中，第一连接部311、第二连接部313和发热部312一体成型，使用一根钨丝弯折而成。通过螺旋的形状，可以保证发热部312在较短的长度条件下具有尽可能大的电阻。而为了尽量降低第一连接部311和第二连接部313的发热量，将第一连接部311和第二连接部313尽量制成直条状。
其他实施方式下，该发热部312也可以是呈直线状，弯折状等。
需要说明的是，在本实施例中使用螺旋状的绕线方式可以在保证热量集中的情况下，保证整个发热部312的温度均匀分布，避免出现局部热脆或热熔断裂。如果引燃温度较低的情况下，也可以随意绕制，甚至直接使用直条状的发热部312，只要在引燃放热焊接剂20前不易断裂即可。
由于发热丝31会发出大量热量，如果通过锡焊等低温焊接方式将发热丝31与第一导线32连接容易使得焊接点在高温下熔化焊接失效。通过物理连接方式将发热丝31与第一导线32连接不仅可以解决上述问题，还可以有效控制成本。
在本实施例中，固定头34整体使用镍铬合金制成，不仅耐高温，导电性能也良好。当然了，也可以采用铜制成。
可选的，第一连接部311与发热部312连接的端部为第一连接端3111，第二连接部313与发热部312连接的端部为第二连接端3131，发热部312以第一连接端3111与第二连接端3131的连线为轴线螺旋而成。
通过该形状，可以有效提高其电阻，增大其发热温度，实现对放热焊接剂20的快速制热。
可选的，第一连接头33的一端设置有两个插孔331，第一导线32的正极端和负极端分别卡设于两个插孔331内且与第一连接头33相对固定。
通过插孔331，可以实现可拆卸的连接，便于安装和拆卸。
结合图11-图15，可选的，点火器40包括壳体41和第二导线45，壳体41内设置有配置成缠绕第二导线45的线盘42和配置成对第二导线45供电的电源44，壳体41的一侧开设有配置成穿设第二导线45的第一开口411，第二导线45伸出第一开口411的一端设置有第二连接头46，第一连接头33与第二连接头46可拆卸的连接。
通过将第一连接头33和第二连接头46连接，可以实现内置的电源44对发热丝31供电，该第二导线45也能有效延长使用者与模具10的距离。
该电源44的种类不限定，可以是5号、7号等不可充电的电池，也可以是锂电池等可以反复充电的电池。本实施例选用可反复充电的电池。
该线盘42可以通过设置弹簧等复位机构，第二导线45拉长后，当松开第二导线45，其可以在复位机构的作用下自动缠绕在线盘42上。
可选的，第二导线45与电源44之间设置有第一开关47。

可选的，第一开关47为滑动开关，滑动开关的控制端设置在凹槽4211内。
本实施例中第一开关47选用三线滑动开关，通过滑动，以实现导通或断开其对应的线路。
可选的，第二连接头46与第二导线45之间设置有第二开关48。

一般的，若电压适合，则发热丝31发热，使放热焊接剂20达到反应所需的温度，铝热反应产生后，反应产生的热可以供该反应持续进行，因此可以断电。若反应过程中高温使得发热丝31熔化，则实现了自动断电。
本实施例中的点火器40可以为引燃器30供电以引燃放热焊接剂20，且通过移动化电源44点燃可以将点火器40微型化、便携化。第二导线45的可伸缩设计使得点燃时，点火器40与引燃器30之间的距离可以控制，保证人员安全。而且通过第一开关47和第二开关48共同控制点燃也进一步保证了人员的安全，提高点燃成功率。
