Inverter device for high-voltage generator

Abstract

The invention relates to an inversion device of high-voltage generator, which is arranged in an inversion chamber integrally mounted in a cabinet of a high-voltage generator, and which comprises one or a plurality of inversion units. Each inversion unit is an assembled modular integral structure formed by mounting a MOS transistor, a radiating fin and an adapter panel of inversion plate on an inversion plate. Each adapter panel of inversion plate is provided with a plurality of twin electric connection holes, which is mounted on a bottom plate of the inversion chamber through an adaptor bracket. The inversion device of high-voltage generator is convenient to assemble, easy to manufacture, and effective to increase work efficiency and reduce false assembly. The cooling mode is so reasonable that a cooling fan is controlled by a temperature switch and needs no long-term operation, and the rear portion of the inversion chamber is provided with a back-up plate with air vent to correspond to an air vent and an air channel arranged on a side door of the cabinet of the high-voltage generator, thereby enlarging draught area, quickening heat dissipation of the inversion chamber, and reducing outward radio-frequency radiation caused by the inversion chamber.

Description

technical field [0001] The invention relates to a high-voltage generator, in particular to a high-voltage generator inverter device. Background technique [0002] The high-voltage generator is the tube power supply device of the X-ray machine. In the similar products of the medical high-voltage generator, the general structure is to uniformly install the inverter board at a certain position in the whole machine box, and connect to each component unit through cables. , and a cooling fan is installed on one side of the inverter board for air cooling and heat dissipation. In the maintenance process of the product, it is necessary to disassemble the relevant cables connected to the inverter board, and the position of the cable terminal is relatively hidden, which will inevitably increase the difficulty of assembly, that is, the product is difficult to assemble during the production process and difficult to operate during maintenance , In the case of assembly and maintenance, it...

AI Technical Summary

Problems solved by technology

In the maintenance process of the product, it is necessary to disassemble the relevant cables connected to the inverter board, and the position of the cable terminal is relatively hidden, which will inevitably increase the difficulty of assembly, that is, the product is difficult to assemble during the production process and difficult to operate during maintenance , In the case of assembly and maintenance, the relevant cables and peripheral components must be removed, which is inefficient and there is a risk of wiring errors, so an easy-to-operate cable terminal structure is required

At the same time, the long-term operation of the cooling fan will easily shorten the life of the fan. When the temperature of the inverter component rises sharply due to unexpected reasons (such as fan stop), an effective cooling control method is required.
