Description

Technical Field

[0001] The utility model relates to the technical field of heaters, in particular to a far-infrared heater. Background Art

[0002] Far infrared heaters are one of the winter heating appliances commonly used in southern my country. They have a simple structure and generally low power, making them suitable for small space applications. However, the existing far infrared heaters need to be turned off when not in use to quickly dissipate heat and cool down. The traditional method of dissipating heat is to open heat dissipation holes, but the heat dissipation efficiency is too low, so the surface temperature will not drop immediately, and the internal heat is likely to damage the electronic components inside the heater, thereby affecting the service life of the heater.
