Description

TECHNICAL FIELD

[0002] The working principle of the existing fan heater is that the heating sheet generates heat, and then the fan blows away the heat generated by the heating sheet, thereby realizing the function of conveying warm air.

[0003] However, the fan of the existing fan heater can only dissipate heat for the originally arranged heating sheet, and when other conditions in the fan heater need to be dissipated, the heat dissipation demand of other components cannot be considered. For example, when a high-power device needs to be arranged in the fan heater and the heat generation is relatively serious, the high-power device cannot be dissipated.

[0004] Therefore, a heat dissipation structure and a fan heater are urgently needed, which can dissipate heat for the heating sheet of the fan heater itself and simultaneously dissipate heat for other high-power devices in the fan heater. SUMMARY

[0008] In the utility model, the heating and heat dissipation system composed of the fan, the heating sheet and the wind path ensures the realization of the basic heat dissipation function of the heat dissipation structure; in addition, the heat dissipation sheet and the mounting position can be installed with the object to be dissipated on the mounting position according to the actual situation, so as to realize the heat dissipation of the object to be dissipated; the above structure can add the heat dissipation sheet while realizing the basic heat dissipation function, and can better realize the heat dissipation of other objects to be dissipated.

[0009] Further, the heat dissipation sheet is located on the wind path. The position of the heat dissipation sheet is set, so that one fan can realize the heat dissipation of the heating sheet and the heat dissipation of the heat dissipation sheet at the same time, which not only has a simple structure, but also can effectively reduce the volume and cost of the actual product.

[0010] Further, the heat dissipation structure further comprises an auxiliary fan for dissipating heat from the heat dissipation fins. The auxiliary fan can dissipate heat from the heat dissipation fins alone, so that the heat dissipation fins can be arranged at will and do not necessarily need to be arranged on the air path of the fan, thereby expanding the applicable range of the heat dissipation structure.

[0011] Further, the heat dissipation structure further comprises an auxiliary fan for dissipating heat from the heat dissipation fins. The auxiliary fan can dissipate heat from the heat dissipation fins alone, so that the heat dissipation fins can be arranged at will and do not necessarily need to be arranged on the air path of the fan, thereby expanding the applicable range of the heat dissipation structure.

[0012] The utility model discloses still provide a kind of application above structure's fan heater, it is characterized in that, including shell and heat dissipation object, the air inlet and air outlet are arranged on shell, the heating fin, fan, heat dissipation fin and heat dissipation object are all installed in shell.

[0013] Further, the heat dissipation structure further comprises an auxiliary fan for dissipating heat from the heat dissipation fins. The auxiliary fan can dissipate heat from the heat dissipation fins alone, so that the heat dissipation fins can be arranged at will and do not necessarily need to be arranged on the air path of the fan, thereby expanding the applicable range of the heat dissipation structure.

[0014] Further, the air inlet and the air outlet are each provided with a filter screen. The filter screen can filter out some larger debris while achieving heating of the fan heater, to ensure safe operation of the fan heater.

[0015] Further, the fan heater further comprises a base, and the shell is rotatably connected to the base. The relative rotatable arrangement of the base and the shell can expand the area range that the fan heater can directly blow on, to facilitate use of the fan heater. The rotatable connection structure is a conventional structure, which can achieve relative rotation between the shell and the base.

[0016] Further, the back top of the shell is further provided with a handle slot. The handle slot can facilitate carrying and moving of the fan heater.
