Abstract
The utility model provides a power supply apparatus, relating to the field of the power supply technology and comprising a transformer rack and a transformer, wherein the transformer rack is a framework structure; the transformer is fixed on transformer rack; a shell is connected with the upper part of the transformer rack; the shell is U-shaped; the shell is upturned above the transformer rack; and a circuit board is arranged in the shell. The power supply device solves the technical problem that in the prior art the transformer is arranged in the power supply box, thus being difficult in heat radiation. The power supply device has the advantages of being compact in structure, occupying less space, and having good heat radiation effect as the transformer directly contacts the environment air.
Description
Technical field
The utility model relates to a kind of technical field of power supply, especially relates to a kind of power supply architecture of transformer-supplied.
Background technology
Power supply is the power resources of various device.Usually, power supply all is arranged in the power supply box of a sealing, and transformer, circuit board etc. are arranged in the power supply box.Chinese patent Granted publication CN202111498U, on January 11 2012 Granted publication date, name is called the utility model patent of " a kind of uninterrupted power supply ", discloses a kind of supply unit.It comprises casing and is installed in the interior transformer of casing.Casing comprises demarcation strip, and demarcation strip is located at box house and box house is divided into lower layer space and upper sheaf space.Casing also comprises the demarcation strip fan that is installed on the demarcation strip and is installed in the interior lower layer space fan of lower layer space.The bottom of casing is provided with ventilation hole.Transformer is arranged in the lower layer space.The power supply of this structure, transformer are arranged in the lower layer space of casing, close on ventilation hole and lower layer space fan, the dissipation of heat that need to transformer be produced by strong-force exhaust is in external environment condition, not only heat radiation difficulty, but also need to install air exhausting device additional, increase energy resource consumption.
Summary of the invention
Be arranged on and be difficult to the technical problem of dispelling the heat in the power supply box in order to solve transformer in the prior art, the utility model provides the supply unit that a kind of floor space is little, make things convenient for the transformer heat radiation.
The technical solution of the utility model is: a kind of supply unit, it comprises transformer yoke and transformer, transformer yoke is frame structure, transformer is fixed in the transformer yoke, the top of transformer yoke is connected with shell, shell is the U font, and shell tips upside down on the top of transformer yoke, is provided with circuit board in the shell.Whole supply unit has only accounted for the area of a transformer, has saved the space.Transformer directly contacts with surrounding air, makes things convenient for heat exchange.Circuit board has jacket, and the protective circuit plate can be not impaired.
As preferably, the bottom of transformer yoke is connected with installation chassis, and the installation chassis cross section is the L shape; Built on stilts transformer yoke is conducive to the transformer bottom heat radiation.
As preferably, the sidewall of shell is provided with ventilation hole; Make things convenient for the transformer top heat dissipation.
Compared with prior art, the beneficial effects of the utility model are: compact conformation takes up room little, and transformer directly contacts good heat dissipation effect with surrounding air.
