Description

Surface insulated PTC hot air generator

本实用新型涉及一种表面不带电的用PTC元件为热源的热风发生器。The utility model relates to a hot air generator with no charge on the surface and using a PTC element as a heat source.

已有的PTC热风发生器一般都是表面带电的，应用在空调机、中央空调设施等高档家电时，存在着比较高的安全隐患。Existing PTC hot air generators are generally charged on the surface, and there are relatively high potential safety hazards when they are used in high-end household appliances such as air conditioners and central air-conditioning facilities.

本实用新型的目的在于提供一种速温、恒温、无明火、安全且有温控作用的表面绝缘的PTC热风发生器。The purpose of the utility model is to provide a surface-insulated PTC hot air generator with rapid temperature, constant temperature, no open flame, safety and temperature control function.

本实用新型是这样实现的，在一发热条的两平面上用高温粘合剂或钎焊方法粘上有散热功能的波纹条，而发热条的两端设有耐高温的塑料座架，在一塑料座架与发热条相接之处，内置温控器和温度保险丝。发热条由PTC元件和金属导电极所构成，它是由其两元件放进一方形金属管内压实而成，且PTC元件与金属导电极用耐高温的绝缘物裹封。The utility model is realized in this way. On the two planes of a heating strip, a corrugated strip with a heat dissipation function is glued on the two planes of a heating strip, and the two ends of the heating strip are provided with a high-temperature resistant plastic seat frame. A temperature controller and a temperature fuse are built in the place where the plastic seat frame and the heating strip are connected. The heating strip is composed of a PTC element and a metal conductive electrode, which is formed by putting the two elements into a square metal tube and compacting, and the PTC element and the metal conductive electrode are wrapped with a high temperature resistant insulator.

下面结合附图和实施例对本实用新型作详细描述。Below in conjunction with accompanying drawing and embodiment the utility model is described in detail.
