Description

Technical Field

[0001] The utility model relates to the technical field of frequency conversion all-in-one machines, in particular to a high-voltage power supply installation structure in an all-in-one machine. Background Art

[0002] The inverter all-in-one integrates multiple high-voltage power supplies. When integrated, these power supplies are cooled and dissipated through a water-cooled plate to maintain stable operation. After integration, the high-voltage power supplies must meet clearance and creepage requirements. Specifically, the shortest straight-line distance between the high-voltage power supply and the water-cooled plate is the clearance, and the distance between the high-voltage power supply and the outer edge of the water-cooled plate is the creepage distance, ensuring spacing and insulation.

[0003] If the high-voltage power supply is directly integrated and assembled according to the electrical clearance and creepage distance, the internal occupied volume will increase. Therefore, it is necessary to optimize the installation structure to meet the electrical clearance and creepage distance requirements in a small volume. Utility Model Content

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] See also Figure 1-Figure 3 As shown, in an embodiment of the present invention, a high-voltage power supply installation structure in an all-in-one machine is proposed, including a water-cooling plate 1, an insulating pad 2 is installed on the water-cooling plate 1, the insulating pad 2 is provided with a plurality of threaded blind holes 3 and a groove structure 4 on both sides of the threaded blind hole 3, specifically, an insulating base plate 13 is provided on the insulating pad 2, and the insulating base plate 13 is locked on the threaded blind hole 3 by a fastener. The threaded blind hole 3 prevents the fastener from coming out of the insulating pad 2 and contacting the water-cooling plate 1, thereby achieving insulation isolation and increasing the electrical clearance between the insulating base plate 13 and the water-cooling plate 1. At the same time, by arranging the groove structure 4 on both sides of the threaded blind hole 3, the outer edge distance length is increased, and the creepage distance between the insulating base plate 13 and the water-cooling plate 1 is increased.

[0028] By installing the high-voltage power supply 7 on the insulating base plate 13, the distance between the power supply 7 and the water-cooled plate 1 can meet the requirements of electrical clearance and creepage distance, and the overall thickness can be effectively controlled; at the same time, when multiple layers of high-voltage power supplies 7 need to be installed, two insulating side plates 5 located between the groove structures 4 are installed on the insulating pad 2 at intervals, and multiple layers of insulating partitions 6 arranged longitudinally are installed on the two insulating side plates 5. The spacing between the stacked high-voltage power supplies 7 is achieved by the spacing distance between adjacent insulating partitions 6 and the spacing distance between the insulating partitions 6 and the insulating base plate 13. Specifically, at least one high-voltage power supply 7 is installed on both the insulating base plate 13 and the insulating partition 6.

[0029] In this way, the high-voltage power supply 7 can be integrated and installed in a relatively small overall volume, and the requirements for electrical clearance and creepage distance can be met.

[0030] It should be noted that the high-voltage power supply 7 is a packaged finished product, and adjacent high-voltage power supplies 7 can be insulated and isolated. Therefore, the number of high-voltage power supplies 7 on each layer is 2, and they are spaced apart along the length direction of the insulating base plate 13.

[0031] At the same time, heat dissipation slots 8 are provided below the high-voltage power supply 7 on both the insulating base plate 13 and the insulating partition plate 6 to meet the heat dissipation effect at each high-voltage power supply 7 position, and combined with the circulating heat dissipation of the water-cooled plate 1 to conduct the surrounding heat, keep the high-voltage power supply 7 operating within a stable temperature range, and ensure safety.

[0032] Specifically, the groove structure 4 includes a plurality of first open grooves 41 evenly distributed and penetrating along the length direction of the insulating base plate 2 , so as to meet the creepage distance requirement along the length direction of the insulating base plate 2 .

[0033] At the same time, the groove structure 4 includes a plurality of second open grooves 42 evenly distributed and penetrating along the thickness direction of the insulating base plate 2 , thereby meeting the creepage distance requirement along the thickness direction of the insulating base plate 2 .

[0034] Specifically, corresponding opening grooves may not be provided in the length direction or thickness direction of the insulating pad 2 when the creepage distance requirement is met, but may be provided at the same time when a small volume is taken into consideration.

[0035] The insulating side plate 5 is fixed by the insulating bottom plate 13. After the insulating side plate 5 is installed with the insulating partition 6, a bracket structure is formed. Therefore, the overall bracket structure also meets the insulation requirements. The insulating partition 6 and the insulating side plate 5 need to have a fixed connection stability. Specifically, a step structure 9 for supporting the insulating partition 6 is provided on the insulating side plate 5, and a supporting protrusion 10 supported on the step structure 9 is provided on the insulating partition 6. The supporting protrusion 10 is supported by the step structure 9 and forms a limit.

[0036] At the same time, a fastening hole 11 is opened on the step structure 9, and a through hole 12 is opened on the support protrusion 10. The fastener passing through the through hole 12 is locked on the fastening hole 11, and the support protrusion 10 and the step structure 9 are locked by the fastener to avoid loosening.

[0037] Specifically, the water-cooled plate 1 is used to circulate cold water to achieve heat exchange and cooling. A circulating water inlet joint and a circulating water outlet joint are integrated on the water-cooled plate 1. A circulating water channel connected to the circulating water inlet joint and the circulating water outlet joint is provided in the water-cooled plate 1.

[0038] At the same time, in order to meet the insulation effect of the water-cooling plate 1, a ceramic layer is provided on the side of the water-cooling plate 1 where the insulating pad 2 is installed, or the material of the water-cooling plate 1 is directly ceramic.
