Abstract
The utility model discloses a structure of high-power high-frequency switch power supply, which includes a front panel, a rear panel, a shell and a bottom plate. A fan and an air switch are installed on the rear panel. The utility model is characterized in that a shielding baffle is installed between the front and the rear panel; a control transformer, a full-bridge rectifier and a control circuit board are installed on the baffle; an IGBT module radiator is suspension arranged on back of the baffle; an IGBT module is installed on the radiator, and the module extends above the baffle through a hole onside. An integrated freewheeling pipe radiator is installed on the bottom plate, integrated freewheeling pipes and a high-frequency transformer are installed on the radiator. The high-frequency transformer and the IGBT module radiator are both arranged transversely, and are both arranged into a front row and a back row. Heavy-current parts and light-current parts of the utility model are successively and respectively installed along the circuit, relative positions of the parts are optimized to achieve a simple, clear and compacted structure, and electromagnetic interference between heavy-current and light-current parts are small, all ensuring design requirements of the utility model for large power application.
Description
Technical field
The utility model relates to a kind of Switching Power Supply, specifically is a kind of air-cooled high-frequency high-power Switching Power Supply structure.
Background technology
The high-frequency high-power Switching Power Supply is of many uses, can be used as welder power.Its package assembly has the base plate formula, and layer-stepping is also arranged.Because the use occasion of high frequency switch power, majority is big for polluting, and electromagnetic interference is serious, and adverse circumstances such as humidity, the Switching Power Supply of existing structure exist weak current part fragile, disturbs greatly problems such as power work instability between the strong and weak electricity device.
The utility model content
The purpose of this utility model provides a kind of compact conformation, perfect heat-dissipating, and light current is kept a public place clean anti-pollution, separates between the strong and weak electricity, and electromagnetic interference is little, the high-power high-frequency switch power supply of stable performance.
The technical solution of the utility model is:
The structure of high-power high-frequency switch power supply, include front and back panels, shell, base plate, blower fan, air switch are installed on the rear board, it is characterized in that being equipped with between the front and back panels shielded partitions, control transformer, full-bridge rectifier and control circuit board are installed on the described shielded partitions, the dividing plate back side is lifted with the IGBT module heat radiator, the IGBT module is installed on the IGBT module heat radiator and reaches the dividing plate top by the perforate on the dividing plate; Whole continued flow tube radiator is installed on the base plate, on the whole continued flow tube radiator whole continued flow tube is installed, on the whole continued flow tube radiator high frequency transformer is installed also, high frequency transformer and IGBT module heat radiator are all transversely arranged, and two row before and after being divided into.
Described air switch is positioned at the top of dividing plate, and full-bridge rectifier, IGBT module, control circuit board are horizontally arranged in the centre of shielded partitions, and its forward and backward row is separately installed with the control transformer of arrangement.
Blower fan of the present utility model is installed in a side of IGBT module heat radiator and whole continued flow tube radiator, and during blower fan work, the heat that radiator produces is taken away in blowing, makes that interior each the parts thermal diffusivity of body is good, has effectively guaranteed the operate as normal of power supply.
The utility model is equipped with the light current parts on the dividing plate, isolates with the forceful electric power parts, is convenient to safeguard, has prevented the electromagnetic interference between the strong and weak electricity parts, has guaranteed the cleaning of light current parts.
The utility model adopts air blast cooling, good heat dissipation effect, and forceful electric power parts and light current parts are installed in proper order by the circuit trend respectively, position relation between each parts is through optimal design, brevity and lucidity, compact conformation, guaranteed the powerful designing requirement of the utility model, power source performance is safe and reliable.
