Abstract
The utility model relates to a switch power supply for jacquard dedicatedly, which solves the technical problem of providing a switch power supply for jacquard especially with good heat dissipation. The utility model employs a unique air duct design, which is compact in structure, efficient in dissipation and of long service life. The strategy to solve the problem is as followed: the power supply is provided with a chassis, a rectifier module, a three phase bridge, an IGBT module, a inductance, two power resistances, a switch transformer, two radiators and two fans. The utility model is characterized in that: the bigger radiator is mounted on the inlet opening horizontally and provided with the rectifier module, the three phase bridge and the IGBT module. Both of the two fans are mounted on the inlet opening side by side. One main air duct against to the rectifier module and one fan is provided with the inductance and the other main air duct against the IGBT module and the other fan is provided with the switch transformer. The outer surface of the two fans and the chassis surface form into two assisting air ducts which are provided with the power resistance respectively. The utility model suits for various power supplies.
Description
Technical field
The utility model relates to power supply, especially a kind of jacquard switch power special.Be applicable in the cabinet that needs ventilation and heat, as all kinds of power supplys.
Background technology
In the prior art, general Switching Power Supply all adopts a blower fan, some power components are dispelled the heat, can not take other power component into account, can only be to the power component that does not have the blower fan heat radiation by the heat radiation of flowing naturally of air in the casing, its temperature approaches the air themperature of casing, and power supply heat sinking efficient is low; On the other hand, in order to make the temperature in the casing unlikely too high, each power component can not lean on too closely on the structural configuration, causes power volume big, is not suitable for the instructions for use of small size, compact power.
Summary of the invention
The technical problems to be solved in the utility model is: the deficiency at prior art exists, a kind of jacquard switch power special with great heat radiation effect is provided, and adopt unique air channel design, compact conformation, the radiating efficiency height, machine life is long.
The technical scheme that the utility model adopted is: the jacquard switch power special, have cabinet, rectification module, three-phase bridge, IGBT module, inductance, power resistor, switch transformer, radiator and blower fan, it is characterized in that: radiator has two, a wherein bigger heat radiator transverse placement is equipped with rectification module, three-phase bridge and IGBT module at the air inlet place on it; Blower fan also has two, is installed in side by side on the air outlet, on rectification module and the pairing main air duct of blower fan inductance is installed, and on IGBT module and pairing another main air duct of another blower fan switch transformer is installed; On the auxiliary air channel that constitutes with the cabinet wall in two blower fan outsides power resistor is housed respectively.
In a side that is positioned at the middle power resistor of cabinet a less radiator is housed.
The beneficial effects of the utility model are: this Switching Power Supply is by middle two main air ducts in the cabinet, the unique design in two auxiliary air channels, both sides, make radiator, inductance, the switch transformer of heat maximum in the casing all obtain better radiating effect, other power component has also obtained good ventilation and heat, thereby has improved machine life; Compact integral structure, volume is less than similar other products.
