Abstract
The utility model discloses a heat radiation system, which comprises a power distribution cabinet. A power device is arranged inside the power distribution cabinet. The top of the power distribution cabinet is provided with a top ventilating opening. A first fan is arranged above the power device. A radiator is arranged right below the first fan. A second fan is arranged right below the radiator. A ventilating duct is arranged between the radiator and the second fan. The bottom of the power distribution cabinet and a base are provided with communicated air outlets. The cold air inside the cabinet flows from top to bottom. The first fan is located right above the radiator. The second fan is located right below the radiator. The second fan is connected with the radiator through the ventilating duct. Heat radiation effects are more effectively guaranteed. Furthermore, the heat radiation system which is rainproof and dustproof enables strong practicality.
Description
Technical field
The utility model relates to a kind of device that is applied in the grid-connected direct-flow distribution system, relates in particular to a kind of cooling system for outdoor grid-connected DC switchgear.
Background technology
The photovoltaic generation of solar energy occupies critical role in the utilization of regenerative resource, development in recent years is swift and violent, and the part technology has realized commercialization, but also comes with some shortcomings.Especially for existing certain contradiction between the sealing of outdoor location and the heat radiation, the device of good sealing effect often radiating effect is bad, and the device of good heat dissipation effect often sealing property does not reach requirement, and problem between the two fails to solve well.
The utility model content
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of cooling system that is used for outdoor grid-connected DC switchgear that can effectively solve heat dissipation problem to be provided.
The utility model is achieved through the following technical solutions:
A kind of cooling system for outdoor grid-connected DC switchgear, include power distribution cabinet, described power distribution cabinet inside is equipped with power device, have the top portion ventilation mouth at described power distribution cabinet top, blower fan one is installed above power device, under described blower fan one, radiator is installed, blower fan two is installed under the radiator, be provided with air duct between described radiator and the blower fan two, have the air outlet that is connected at bottom and the base of power distribution cabinet.
Described top portion ventilation mouth adopts louver structure, has effectively avoided advancing rain because of the air inlet negative pressure and has advanced dirt, and its sealing is guaranteed.
Operation principle of the present utility model is: by blower fan one work cold air is sucked from the top portion ventilation mouth, cold air will directly be passed to the radiator that is arranged under the blower fan one, to supply with main heater element power device heat radiation needs, discharge via air duct and blower fan two, last hot-air flows in the atmosphere by air outlet again.The utility model has the advantages that: it is from top to bottom that the inner cold air of the utility model flows to, and blower fan one is positioned at directly over the radiator, and blower fan two is positioned under the radiator, be connected with radiator by air duct, more effectively guarantee radiating effect, and the energy rain-proof dust-proof, practical.
