A heater includes a casing, a heating module, a phase change heat conducting body and a heat absorbing body. A chamber is formed in the casing, and air intake holes and ventilation holes are formed on the casing and interconnected with the chamber. The heating module and the phase change heat conducting body are fixed into the chamber of the casing, and an end of the heat conducting body is attached with the heating module, and another end of the heat conducting body is connected to the heat absorbing body. The heat absorbing body is composed of heat absorbing plates, and an air flow passage is formed between any two heat absorbing plates and installed corresponding to the ventilation hole, so that a hot air flow discharged from the heater can be controlled under a predetermined temperature to improve the safety of using the heater.
