Detailed Description

The following description is only for the preferred embodiment of the present invention, and the protection scope of the present invention is not limited thereby, the present invention will be further explained with reference to the drawings and the embodiments.

Example 1, see FIGS. 1-2: the utility model relates to a tail gas waste heat recovery reradiation equipment of gas electric fan heater, it is installed and is used on the gas electric fan heater, including tail gas discharge pipe 1, heat transfer chamber 2, heat exchanger 3, heat radiation plate 4 and circulating pump 5, tail gas discharge pipe 1 is installed on the tail gas export of gas electric fan heater, is the perpendicular upwards setting, and it is by supreme down insert extremely in the heat transfer chamber 2, heat transfer chamber 2 is sealed casing to fix on tail gas discharge pipe 1, the intercommunication is equipped with the outdoor discharge pipe 6 that upwards sets up perpendicularly on it, and outdoor discharge pipe 6 communicates with outdoor environment for exhaust gas. In the present embodiment, one heat recovery device is provided, and a plurality of heat recovery devices may be attached to the outdoor discharge pipe 6 as the exhaust gas discharge pipe 1.
