【精】Ptc heating device一种PTC加热装置

一种PTC加热装置,可广泛地用作各种电器(如电子驱蚊器,电子罐等)的热源. One kind of PTC heating device can be widely used for various electrical appliances (such as electronic insect repellent, electronic cans, etc.) of heat. 该PTC加热装置包括一个瓷盒,瓷盒中放入一个电极结构件,该电极结构件由上,下表面都有电极的PTC加热元件和二块电极板组成,该PTC加热装置还包括一块散热板,该板通过绝缘板置于电极结构件之上,散热板的凸缘上有一些固定爪,可靠地将散热板和瓷盒固定在一起,并保证固定爪和接线端之间有足够的绝缘距离. The PTC heating device comprises a ceramic box, placed in a porcelain box electrode structure, the electrode structure by the upper and lower surfaces has a PTC heating element and a second electrode composed of the electrode plates, the PTC heating device further comprises a heat sink plate which is placed above the electrode plate through the insulating structural member, there are a number of fixed jaws on the flange of the heat radiating plate, the heat radiating plate and securely fixed together ceramic cartridge, and to ensure that there is sufficient between the fixed jaw and terminal insulation distance. 上电极板上有一狭窄段,过流时会熔断. The electrode plate with a narrow segment, will fuse overcurrent.
