In this paper, a thermal simulation model of a LED driver was established. The thermal field and thermal stress analysis of the driver was done by using the software EFD Pro 8.2, and the temperature rise from various parts and the temperature field distribution of the PCB were obtained. By analyzing the reasons leading to overheating and unideal heat distribution, corresponding thermal simulation using an improved model was carried out. Finally, the comparison and analysis of experimental measurement results and simulation results were given.

The design cross sectional area of shunt is calculated by the product of carrying rated current ratio and Bi-2223/AgAu matrix and shunt resistivity ratio. When quenching happens, shunt carries more current to void burn out or overheat of superconductor. Shunt which provides an enough heat sink can restrain the temperature rising of HTS section too fast.

分流器横截面积确定基于分流器与Bi-2223基体AgAu的电阻率对失超后电流分配比，这样保证超导体转人电阻态后分流器分流大部分电流，同时由于分流器具有很好热沉作用，抑制超导体温度迅速上升，从而避免超导材料烧毁或过热。

In fact, because of using some methods of predigesting or approximating and complexity of heat changing process etc. when design to form new-type heat exchanger, we must determine the actual heat transfer performance, also to the old heat exchanger.

实际上由于设计过程中采用某些简化或近似的方法，并且换热器换热过程的复杂性等因素，对于设计制造而形成的新型换热器必须测定其实际的传热性能，对于使用过的旧的换热器也需如此。

底锅分为干表面和湿表面二部分，加热时可产生过热的高温蒸汽进行灭菌，当蒸汽进入冷凝器底部时，则遇冷被冷凝成水，经回水管又流回底锅，水———汽在锅内闭路循环，直至冷凝器中水温达到90℃以上时为止，此时蒸汽则通过出气管外逸，吹动哨片发出响声报警。

Because the sensors in the electromagnetic field are large, the temperature of the micro hot spot cannot be measured.

但在实际的应用中，对于谐振腔内部的电磁场分布和温度分布的测量是比较困难的，需要将多个感应探头放置于反应场中进行感应测量，而感应器本身的介入对电磁场分布和温度分布就产生了改变，并且宏观的感应器是不可能测试出微观中存在的局部点的过热现象。
