热风枪是一种可手持式,用来吹出热气流的工具,通常热气流气温介于100 °C至550 °C 之间(200-1000 °F)。某些型号可以吹出760 °C (1400 °F)的气流。热风枪一般来说有个长管型的机身来引导加热目标、有个手柄在其上,并附有扳机,类似手枪的造型,由此得名。较轻的热风枪型号非常酷似于吹风机

结构

热风枪内会有一个热源,通常为电热元件,但有些型号使用瓦斯加热;一个能转移热空气的机械装置例如电动风扇(若热流本身的气压足够,则不需要。);一个喷嘴来集中气流,可能是一个简单的定向管,或者特别设计来集中热气流的形状;一个外壳来包含上述零件并保护使用者;一个机械装置例如板机来开关电源;一个手柄;还有一个内建或外加的固定器来达到不须手持的功能。

用途

热风枪通常用于物理学材料科学化学工程学或其他实验室或工作场所。不同种类和温度的热风枪搭配不同的气流配置,可以用于除油漆、紧缩热缩套管热缩膜英语Shrink wrap、和热缩英语Shrink wrap包装、干燥木材、融弯塑胶、软化黏合剂、和解冻结冰的管路等。[1] 有些类型的热风枪可用于电子学领域,作为解焊英语Desoldering重工表面黏着电路板元件。热风枪也可以安全地模拟装置过热状况,用于测试过热保护机制。

若要移除含铅油漆英语Lead paint时,需要使用590 °C (1100 °F)以下的热源以使蒸发的风险最小化。[2]
