Abstract
A high-efficiency heat-radiation power supply relates to the technical field of switching power supply, comprises a housing and a cover plate arranged on the housing and is characterized in that one side of the housing is provided with a vertically-arranged cooling duct; an outer end of the cooling duct is equipped with a ventilation opening; the inner end of the inner side of the cooling duct is provided with a fan exhaust hole; and the outside of the fan exhaust hole is equipped with a fan. As the fan is installed on the outside of the fan exhaust hole, cooling performance is raised. In addition, a good cooling effect can be achieved by the adoption of a common fan with a large diameter, costs are reduced, and service life of the power supply is raised.
Description
Technical field
The utility model relates to the switch power technology field, is specially a kind of high efficiency and heat radiation power supply architecture.
Background technology
Power type in the market is a lot, and the heat dispersion of power supply is to power source life and use safety to have bigger influence.
Structure of the prior art generally comprises the heat dissipation wind channel that is arranged on housing one side, the fan installing hole that the inner of the inboard of heat dissipation wind channel arranges, fan is installed in the inboard of fan installing hole, and fan generally adopts the snail fan, adopt the power supply heat sinking effect of this kind arrangement relatively poor, and the cost of snail fan is higher, the life-span is not long.
Summary of the invention
The purpose of this utility model provides the power supply that a kind of radiating effect is better, useful life is long.
The technical scheme that realizes above-mentioned purpose is: the high efficiency and heat radiation power supply, comprise the cover plate on housing and the housing, it is characterized in that: a side of described housing is provided with the heat dissipation wind channel of vertical layout, the outer end of heat dissipation wind channel is provided with ventilating opening, inboard the inner at heat dissipation wind channel has fan hole, and the outside of fan hole is equipped with fan.
The utility model is installed in the outside of fan hole with fan, has improved heat dispersion, and has adopted common larger diameter fan just can reach better radiating effect, has reduced cost, has improved the useful life of power supply.
