Description

Technical Field

[0001] This utility model belongs to the field of high-frequency power supply technology, and specifically relates to a high-frequency power supply structure. Background Technology

[0002] Electromagnetic induction heating, or simply induction heating, is a method of heating conductive materials such as metals. It is mainly used for metal hot working, heat treatment, welding, and melting. Induction heating utilizes electromagnetic induction to generate an electric current within the material being heated, relying on the energy of these eddy currents to achieve the heating purpose. The basic components of an induction heating system include an induction coil, an AC power supply, and a workpiece. Depending on the object being heated, the coil can be made into different shapes. The coil is connected to the power supply, which provides alternating current to the coil. The alternating current flowing through the coil generates an alternating magnetic field that passes through the workpiece. This magnetic field induces eddy currents in the workpiece, thus heating it. Therefore, electromagnetic induction heating technology is widely used.

[0003] High-power high-frequency induction power supplies are frequently used in factories. During operation, the numerous electrical power components inside generate a significant amount of heat. Overheating can damage these components, affecting their normal operation and increasing the time and cost of routine maintenance. Therefore, heat dissipation is necessary. Currently, high-power high-frequency induction power supplies suffer from complex structures, low overall mechanical strength, poor heat dissipation, and reduced lifespan of internal electrical components.

Cooling water is used to dissipate heat inside the chassis, which has excellent heat dissipation effect and will not affect the service life of the internal electrical components. The water cooling method results in low noise.

[0027] like Figure 1 As shown, the chassis includes a left side door 3, on which a water pressure gauge 31 is installed. A power output port 33 is located below the water pressure gauge 31. A power cover 32 is installed around the power output port 33, and the power cover 32 protects the power output port 33.

[0035] Specifically, the hydrothermal capacitor 72 is provided with connecting copper pipes 73, specifically two pipes, namely a first copper pipe 731 and a second copper pipe 732. Water nozzles are respectively provided at both ends of the first copper pipe 731 and the two ends of the second copper pipe 732. Preferably, the bottom end is the water inlet and the top end is the water outlet, which improves the cooling effect.

The water inlet collector 41 and water outlet collector 42 are respectively connected to the output and input ends of the circulating water supply system. The circulating water supply system is a common technology and will not be described in detail here. The branch water pipes are connected to water nozzles via flexible hoses, preferably forming the following water path:

[0040] 1. The primary coil 734 and the secondary coil 733 each form a water channel;

[0041] 2. The first copper pipe 731 and the second copper pipe 732 installed on the hydrothermal capacitor 72 each form a water channel;

[0042] The various waterways are independent of each other and not interconnected.

[0043] The circuit is formed as follows: the water-heating capacitor 72 and the output transformer 71 are connected through the connection between the first copper tube 731, the primary coil 734 and the second copper tube 732; the output transformer 71 and the capacitor copper plate 68 are connected through the terminal block 735 set on the secondary coil 733. The two can be electrically connected by wires or hollow copper tubes.

[0044] like Figure 4 As shown, a UPS 74 is installed on the side of the internal chassis, and the UPS 74 is electrically connected to transformer 91 via wires. A UPS, or Uninterruptible Power Supply, is a type of uninterruptible power supply containing an energy storage device. It is mainly used to provide uninterrupted power to equipment with high power stability requirements. When the mains input is normal, the UPS stabilizes the mains voltage and supplies it to the load. At this time, the UPS acts as an AC voltage regulator, and it also charges its internal battery. When a power outage occurs, the UPS immediately switches from the battery's DC power to the load using an inverter, continuing to supply 220V AC power to maintain normal operation of the load and protecting the load's hardware and software from damage. UPS devices typically provide protection against both overvoltage and undervoltage.

[0045] like Figure 1As shown, the chassis includes a front door 1. A touch screen 11 is installed on the upper part of the front door 1.

[0047] like Figure 3 As shown, the chassis is provided with support bars 10. Specifically, the chassis is provided with support bars 10 around its four sides, and a number of support bars 10 are symmetrically spaced on the two sides of the chassis. The support bars 10 are used to provide support and reinforcement.

[0048] The specific working process of this utility model is as follows:

[0049] The electrical components installed inside the chassis form a high-frequency induction power supply structure. When the power supply is working, the internal water circuit of the chassis is used to cool the inside of the chassis, thereby achieving the purpose of heat dissipation.

[0050] Specifically, cooling water enters from the inlet water collector 41, passes through the water distributor and enters each water nozzle. The cooling water enters the first copper pipe 731, the second copper pipe 732, the primary coil 734 and the secondary coil 733 through the water nozzle at one end of the hollow copper pipe. After flowing in the hollow copper pipe, it comes out through the water nozzle at the other end. The water coming out of the water nozzle is collected by the water distributor and flows out into the outlet water collector 42 to remove the heat generated by the electrical components during operation.

[0051] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features.
