So as to achieve the purpose that one fan 220 radiates heat to a plurality of heat radiating members 230 and a plurality of control boards 240.

It is understood that each control board 240 is connected to one heat sink 230, and the heat sink 230 serves to dissipate heat from the control board 240 to reduce the temperature rise of the control board 240. The fan 220 operates to draw cool air from the outside of the housing 210 into the mounting cavity 122 through the air inlet 118, and to guide the air flow in the mounting cavity 122 to each of the heat dissipating members 230 and the control panel 240 via the air inducing structure 130. The cold air passing through the heat sink 230 carries away the heat at the heat sink 230 and exits the heating device 200 through the heat outlet 212. The cold air passing through the control plate 240 takes away the heat at the control plate 240 and exits the heating device 200 through the heat-dissipating outlet 212. This arrangement ensures that the operating temperature of the control panel 240 is maintained, providing an effective and reliable structural support for ensuring the useful life of the heating device 200.

In the present application, the term "plurality" is intended to mean two or more, unless explicitly defined otherwise.
