Description

Technical Field

[0001] The invention relates to a combined inductor for improving the heat dissipation effect of immersion liquid cooling or air cooling. Background Art

[0002] The principle of magnetic inductance is to add varying numbers of current-carrying metal frames to the magnetic component so that when current passes through the inductor, electromagnetic energy is generated, thereby changing the current and voltage values ​​of the circuit.

[0003] The so-called combined magnetic inductor is mainly composed of one or more magnetic core components and at least one metal conductive sheet. The magnetic core is mainly a powder iron core or a ferrite core, and the metal conductive sheet is usually made of copper metal plate, which is stamped into a bent metal frame containing input and output ends.

[0004] The combination of the combined inductor is to place a metal frame into a reserved accommodation space on the inner edge of a magnetic core and then glue it together to complete the combined electrical inductor. When the inductor is energized, the magnetic core and the current-carrying metal frame generate electromagnetic energy through electrical interaction, thereby achieving the expected inductance performance.

[0005] The so-called block combination inductors include a variety of structural products based on the appearance or structural shape of the core, among which EE type (EE Core), EI type (EI Core) and HI type (HI Core) are the most popular. EE type and EI type combination inductors are further divided into single-loop inductors with a single-piece metal frame (Flat Pac) and double-loop inductors with a double-piece metal frame (TLVR).

[0006] Generally, the metal frame and magnetic core of a conventional block-type combination inductor are tightly combined and fixed with adhesive. The heat can only be dissipated by surface conduction, and there is no heat dissipation optimization design for a liquid cooling system where the entire circuit board is immersed in liquid, or a traditional air cooling system with fan blowing. Summary of the invention

[0007] In view of the heat dissipation deficiency of the conventional combined inductor as described above, an object of the present invention is to provide a combined inductor that improves the heat dissipation effect of liquid cooling or air cooling.

[0008] To achieve the above-mentioned purpose, the present invention provides a combined inductor that improves the heat dissipation effect of liquid cooling or air cooling. A bonding flange is provided on the left and right magnetic cores of the EE type and EI type inductors or the upper and lower magnetic cores of the HI type inductors to generate a gap between the two combined magnetic cores, or a gap is reserved at the two sides of the magnetic core of the EE type, EI type or HI type inductor corresponding to the metal frame, so that a flow gap is generated when the inductor is immersed in liquid cooling or air cooling. In addition to the flow of heat dissipation, the gap can also discharge the gas between the gaps, and effectively improve the liquid or air heat dissipation effect of the combined inductor.

[0009] As described above, the technical content of the present invention is applicable to EE type, EI type or HI type inductors which are popular in the market, and can obviously increase the heat energy generated when the inductor is powered on, and provide obvious cooling and heat dissipation performance.
