[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figures 1 to 4 As shown, a high-frequency combined electrical device according to an embodiment of the present invention comprises: a high-frequency transformer 1 , a high-frequency inductor 2 and a housing 3 .

[0023] The high-frequency transformer 1 and the high-frequency reactor 2 are encapsulated in the housing 3. In this way, the high-frequency transformer and the reactor are combined and encapsulated in the same aluminum alloy housing, which greatly saves installation space, reduces the connection conduction length, and facilitates planning and layout. In addition, the integrated design is also conducive to standardized process selection, modularization, etc.

[0024] The high-frequency transformer 1 and the high-frequency reactor 2 maintain a working distance, and the two are electrically connected by a cable. In one embodiment, the high-frequency transformer 1 and the high-frequency reactor 2 are encapsulated in the housing 3 in a potting manner, that is, the high-frequency transformer 1 and the high-frequency reactor 2 located in the housing 3 are filled with a thermally conductive resin 5 between the housing 3, and the thermally conductive vertical 5 not only fixes the high-frequency transformer 1 and the high-frequency reactor 2, but also has the function of improving the heat dissipation effect. In one embodiment, the thermally conductive resin is a thermally conductive resin of model MC62.

[0025] Correspondingly, the housing 3 is provided with a plurality of terminals 4 for electrically connecting the high-frequency transformer 1 and the high-frequency reactor 2. Any terminal 4 adopts a copper oblong column structure. In one embodiment, the terminals 4 of the high-frequency transformer 1 and the high-frequency reactor 2 are respectively arranged on both sides of the top surface of the housing 3, and there are three terminals 4 on any side, and the three terminals 4 are distributed at the three vertices of a triangle.

[0026] The shell 3 is used as a space for encapsulating the high-frequency transformer 1 and the high-frequency reactor 2, and is made of aluminum alloy. Specifically, the shell 3 is formed with: a main space 31 and an expansion space 32. The expansion space 32 protrudes symmetrically from both sides of the shell 3 and is connected to the main space 31. In this way, the extra space is fully utilized while ensuring performance. In one embodiment, the expansion space 32 is a trapezoidal space formed on both sides of the main space 31.

[0027] In addition, the bottom of the housing 3 is coated with thermal conductive silicone grease.

[0028] Based on the same technical concept, the present invention also provides an auxiliary power supply system, which includes: a high-frequency combined electrical device and a heat sink. The high-frequency combined electrical device is the high-frequency combined electrical device described above, and the bottom surface of the high-frequency combined electrical device is installed on the heat sink and forms a heat conduction relationship with the heat sink.

[0029] As mentioned above, the bottom of the shell of the high-frequency composite electrical device is coated with thermal grease. The high-frequency composite electrical device is installed closely to the radiator through the thermal grease, which can take away a lot of heat, reduce the temperature rise, and reduce the impact of the high temperature of the product on the surrounding heat-sensitive devices.

[0030] The high-frequency combined electrical device is a high-frequency combined electrical device as described above, and the fan is arranged toward the high-frequency combined electrical device. In this way, the fan concentrates the heat dissipation of the high-frequency input and the surface of the high-frequency reactor, takes away a large amount of heat, plays a role in reducing the temperature rise, and reduces the impact of the high temperature of the high-frequency product on the surrounding heat-sensitive devices. In one embodiment, the length direction of the high-frequency combined electrical device is arranged along the blowing direction of the fan, so that the high-frequency combined electrical device and the fan have a relatively large effective area in the airflow being blown, which is conducive to improving the heat dissipation effect.

[0031] In summary, the present invention adopts a high-frequency transformer and a reactor combined design, which are integrally encapsulated in the same aluminum alloy housing, greatly saving installation space, reducing the connection conduction length, and facilitating planning and layout. Then, by applying thermal conductive silicone grease and installing it close to the radiator, a large amount of heat is taken away by the radiator, which plays a role in reducing temperature rise and reducing the impact of the high temperature of the product on surrounding thermal sensitive devices. In addition, the integrated design is also conducive to standardized process selection, modularization, etc.

[0032] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
