Auxiliary heat dissipation device applied to air conditioner and air conditioner

The utility model relates to the technical field of temperature adjusting electric appliances, and discloses an auxiliary heat dissipation device applied to an air conditioner and the air conditioner. The auxiliary heat dissipation device applied to the air conditioner comprises a sensing assembly, a heat dissipation assembly and a control assembly. The sensing assembly is used for sensing a temperature parameter of a target component of the air conditioner; the heat dissipation assembly is used for dissipating heat of the target component, is arranged on the target component and communicates with the air inlet side of the air conditioner; the air inlet side can guide airflow to dissipate heat of the heat dissipation assembly, and the heat dissipation assembly guides the airflow participating in heat dissipation to flow to the air inlet side to participate in heat exchange work of the air conditioner. The control assembly is connected with the sensing assembly and the heat dissipation assembly and used for re
