Gasifier and liquid material gasification device

The invention provides a gasifier and a liquid material gasification device. The vaporizer includes a vaporizing chamber that heats a liquid material to vaporize the liquid material, and a heat exchange element disposed in the vaporizing chamber. The vaporizing chamber has grooves on the inner surface. Therefore, the gasification performance of the liquid material can be improved, and gasification of the liquid material under large flow can be realized. 本发明提供气化器和液体材料气化装置。气化器包括加热液体材料而使液体材料气化的气化室和配置在气化室内的热交换元件。气化室在内表面具有槽。由此，能够提高液体材料的气化性能，实现液体材料的大流量下的气化。
