Description

Technical Field

[0001] This utility model relates to the field of transformer technology, and in particular to a waterproof high-frequency transformer structure. Background Technology

[0002] High-frequency transformers, as core components in power electronic equipment, are widely used in switching power supplies, inverters, and industrial control.

[0003] Traditional high-frequency transformers have insufficient waterproof performance in practical applications. In outdoor or humid environments, the weak sealing structure often allows moisture to enter, leading to a decline in insulation performance or short-circuit faults. At the same time, the heat dissipation efficiency is low. High-frequency transformers generate a lot of heat during operation. Traditional designs rely on natural heat dissipation or simple metal casing for heat conduction, which has limited heat dissipation capacity and can easily lead to excessive temperature rise, reducing equipment life and efficiency.

[0029] Example 1

[0030] Reference Figure 1 Figure 2 This is the first embodiment of the present utility model. This embodiment provides a waterproof high-frequency transformer structure, which can achieve the unity of waterproofing, heat dissipation and mechanical stability of the high-frequency transformer, and significantly improve its reliability and service life in complex environments. It includes a preliminary sealing unit 100, including a metal base 101, and an insulating cover 102 is provided on the metal base 101.

[0031] The heat dissipation unit 200 includes a mounting groove 201 formed on a metal base 101, a coil mounting component 202 provided on the mounting groove 201, two sets of pressure plates 203 provided on the metal base 101, and heat dissipation fins 204 provided on the coil mounting component 202.

[0032] The secondary sealing unit 300 includes a sealing ring 301 disposed on a metal base 101, threaded protective caps 302 disposed on both sides of the insulating cover 102, and a shock-absorbing pad 303 disposed at the bottom of the metal base 101.

[0033] The metal base 101 of the initial sealing unit 100 and the insulating cover 102 form a basic sealing structure to protect the internal components. The coil mounting component 202 in the heat dissipation unit 200 is embedded in the mounting groove 201 of the metal base and the coil assembly is fixed by two sets of pressure plates 203. The heat dissipation fins 204 quickly dissipate the heat generated by high-frequency operation. The secondary sealing unit 300 enhances the sealing performance between the base and the cover through the sealing ring 301, the threaded protective cap 302 seals the wiring port to prevent moisture intrusion, and the bottom shock-absorbing pad 303 absorbs external vibrations, ensuring that the overall structure maintains its sealing performance, heat dissipation efficiency, and mechanical stability in complex environments.

[0034] Example 2

[0035] Reference Figures 1 to 3This is the second embodiment of the present invention. Unlike the previous embodiment, the coil mounting component 202 includes a heat dissipation substrate 202a fixedly disposed within the mounting groove 201. A coil groove 202b is formed on the heat dissipation substrate 202a. A first terminal 202c is provided on one set of pressure plates 203, and a second terminal 202d is provided on another set of pressure plates 203. A high-frequency coil is disposed on the coil groove 202b and sealed within the coil groove 202b with sealant. The heat dissipation substrate 202a is made of copper-aluminum alloy, with heat dissipation fins 204 extending from its bottom and exposed on the outer surface of the metal base 101. The two ends of the magnetic core of the high-frequency coil are connected to the first terminal 202c and the second terminal 202d and fixed by the pressure plates 203. An insulating buffer pad is provided between the pressure plates 203 and the magnetic core.

[0036] A stepped sealing groove is provided at the joint between the metal base 101 and the insulating cover 102. The sealing ring 301 is filled in the stepped sealing groove. A waterproof terminal is embedded in the side wall of the metal base 101. The inner end of the waterproof terminal is welded to the first terminal 202c. The outer end of the waterproof terminal is provided with a threaded protective cap 302. A hydrophobic and breathable membrane and a spring pressure plate are provided on the insulating cover 102.

[0037] When the high-frequency transformer is running, the current enters the first terminal 202c through the waterproof terminal, and is electromagnetically induced by the high-frequency coil 301 under the action of the magnetic core. The heat is quickly dissipated through the heat dissipation substrate 202a and the bottom heat dissipation fins 204. The stepped sealing groove of the metal base 101 and the insulating cover 102 and the silicone sealing ring 301 block external moisture, and the hydrophobic and breathable membrane balances the internal air pressure to ensure long-term stable operation. The pressure plate 203 and the insulating buffer pad work together to fix the magnetic core to prevent displacement or short circuit caused by vibration, so as to achieve efficient and safe energy conversion.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
