Description

  The present invention relates to a transformer improvement structure of a high-frequency switch type DC rectifier, and more particularly, a transformer formed of a ring-shaped iron core (iron powder core, nanocrystal, or amorphous silicon). The side conductive metal (copper wire) winding method and the secondary side output a large current and low voltage, and the secondary side relates to a new transformer formed by a modular type or a module block type. .

The known DC DC high current low voltage rectifier transformer structure is mainly controlled by SCR silicon controlled rectifier, mainly high current low voltage DC power supply (output 1-50V, 1A-50000A) or high frequency Used for interchangeable (switched DC) DC rectifiers. Its application is mainly applied to surface treatment (electroplating), such as PBC electroplating, IC electroplating, continuous electroplating, metal plating, electrolysis, charger, electrodeposition coating.

  The SCR silicon controlled rectifier transformer is mainly composed of a silicon steel piece as the iron core of the transformer, composed of conductive metal material by the primary side copper wire winding method and the secondary side copper wire winding method. In order to cope with the current low voltage, the transformer of the SCR silicon controlled rectifier has high iron loss and copper loss, low efficiency, and severe electric and energy consumption. In addition, the volume is very large and a high temperature is generated at the time of large current low voltage rectification. Therefore, a cooling device is generally required, and cooling is performed by, for example, a strong wind fan, but noise is generated. Adopting an oil-type cooling system causes contamination and low rectification efficiency.

The object of the present invention is to provide a transformer improvement structure of a high frequency exchange type (switched DC) DC rectifier, and in particular, to provide a new design of a transformer applied to a high current exchange voltage rectifier of large current and low voltage. To improve the problem.

  In order to achieve the above-mentioned object, the transformer structure of the high-frequency exchange type DC rectifier of the present invention is mainly composed of a ring-shaped iron core (iron powder core, nanocrystal, or amorphous silicon), and a primary side copper wire winding. System and secondary side (originally output by copper wire or copper plate winding method) Newly developed module or module block, and secondary side module or secondary side module block The inside is cooled by water, and the ring-shaped iron core and the primary coil and the secondary module simultaneously maintain normal temperature, improve the efficiency of the transformer, achieve the power saving effect, The volume is reduced to reduce the weight, and in particular, the inside of the transformer is cooled by a cooling water pipe, and the cooling water can be collected and does not generate contamination.

  The transformer according to the present invention maintains a normal temperature, improves the efficiency of the transformer, achieves a power saving effect, and reduces the volume of the transformer to reduce the weight. Cooled by the cooling water pipe, the cooling water can be recovered and does not generate contamination.

  First, FIG. 1 is a three-dimensional exploded view of the present invention, which mainly comprises a ring-shaped iron core 1 and a secondary side module 2. The ring-shaped iron core 1 is a primary side coil 10 by a primary side copper wire winding system. The secondary module 2 is composed of a combination of both semicircular module blocks 21 and 22, and an annular tank 20 is formed in the center, and the coupling end is isolated by an insulating material 23. A cooling launch hole 210 and a cooling drain hole 220 are installed on the secondary module 2.

  Next, as shown in FIG. 2, the present invention and the known SCR silicon controlled rectifier generate a transformer with a piece of silicon steel, and differ from the high current low voltage method of the high frequency exchange type (switch type DC) DC rectifier. It is a high-frequency exchange type, high-current low-voltage transformer, and mainly uses a primary coil 10 and a secondary module 2 by a ring-shaped iron core 1 (iron powder core, nanocrystal, or amorphous silicon). The transformer is formed by the newly developed modular design. Furthermore, the amount of heat generated by the large current is carried by the cooling water, thereby improving the efficiency of the transformer and achieving a power saving effect.

  The cooling water device refers to the sectional view in the axial direction of the secondary module 2 in FIG. 3, and the annular iron core 1 forming the primary coil 10 is placed in the secondary module 2 central annular tank 20, During high-current low-voltage rectification, high temperature is generated, so it cools and maintains normal temperature, improves transformer efficiency and achieves power saving effect. In the present invention, a cooling launch hole 210 and a cooling drain hole 220 are installed on the upper and lower sides of the secondary module 2, and during rectification, cooling water enters the secondary module 2 from the cooling launch hole 210 and cools and drains. It flows out of the hole 229, takes heat, and maintains the secondary module 2 at a normal temperature.
