Heat dissipation device for network type direct-current power supply on-line monitoring equipment

The utility model relates to the technical field of power supply monitoring equipment, and discloses a heat dissipation device used for network type direct current power supply on-line monitoring equipment, comprising a heat dissipation structure used for heat dissipation of the monitoring equipment; the fixing structure is arranged on the heat dissipation structure and used for being installed on the monitoring equipment, at the moment, the flow dividing barrel divides sucked air into two parts, a large amount of air sucked from the edges of the fan blades enters the conversion box from the outer side wall of the flow dividing barrel, and heat dissipation is conducted on the part, generating much heat, of the surface of the monitoring equipment; less air sucked from the middle area of the fan blades enters the shunting barrel, reaches the heat dissipation box, dissipates heat of the part, generating less heat, of the surface of the monitoring equipment, and finally flows into the conversion box through the h
