[0023] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. Now, the preferred embodiments of the present application will be described in detail with reference to the drawings.

[0024] As shown in Figure 1 and Figure 2 , the present application provides a specific embodiment of an epoxy insulation board.

[0025] An epoxy insulation board, referring to Figure 1 and Figure 2 , the epoxy insulation board comprises a first surface 100 and a second surface 200, the first surface 100 is used for installing a coil, and the second surface 200 is uniformly provided with a plurality of independently arranged transverse protrusions 210 and longitudinal protrusions 220, the plurality of transverse protrusions 210 are all parallel to the length side of the second surface 200, and the plurality of longitudinal protrusions 220 are all perpendicular to the transverse protrusions 210.

[0026] Specifically, the epoxy insulation board is a common insulating material, which has excellent electrical insulation performance and can effectively isolate the conductive part in the electrical equipment; it also has good heat resistance and can work in a relatively high temperature environment without softening or melting; it can also be used as a structural part or support plate; in the present embodiment, the epoxy insulation board is used to install an electromagnetic coil and is applied to an electromagnetic device or a transformer; wherein the first surface 100 of the epoxy insulation board is used to install the electromagnetic coil, and the second surface 200 of the epoxy insulation board is used to connect with other equipment to install the electromagnetic coil into the corresponding application scene.

[0027] Referring to Figure 1 and Figure 2, a plurality of independent transverse protrusions 210 and longitudinal protrusions 220 are arranged on the second surface 200 of the epoxy insulation board, and the transverse protrusions 210 and the longitudinal protrusions 220 are uniformly and spacedly distributed on the second surface 200. The design of the transverse protrusions 210 and the longitudinal protrusions 220 can effectively improve the mechanical strength of the epoxy insulation board on the one hand, so that it can bear longer electromagnetic coils. On the other hand, the transverse protrusions 210 and the longitudinal protrusions 220 have a certain height. When the second surface 200 of the epoxy insulation board is installed on the external equipment, the second surface 200 and the external equipment will be separated by the transverse protrusions 210 and the longitudinal protrusions 220 to form a heat dissipation space, so as to avoid direct contact between the second surface 200 and the external equipment, thereby improving the heat dissipation efficiency. In addition, the transverse protrusions 210 and the longitudinal protrusions 220 are arranged at intervals, so as to form an air duct between the transverse protrusions 210 and the longitudinal protrusions 220, which is convenient for heat dissipation. When the epoxy board is applied in a high-temperature environment, it can dissipate heat in time to prevent other electronic equipment in the environment from overheating and being damaged.

[0028] Further, the plurality of transverse protrusions 210 are parallel to the length side of the second surface 200, and the plurality of longitudinal protrusions 220 are perpendicular to the transverse protrusions 210; so that the overall symmetry of the epoxy insulation board is better, and the stress in application is better, thereby improving the installation stability of the entire electromagnetic coil.

[0029] In one embodiment, referring to Figure 1 and Figure 2 , the plurality of transverse protrusions 210 are arranged in sequence and at intervals along the length direction of the second surface 200 to form isolation zones 230, and the second surface 200 is uniformly provided with a plurality of isolation zones 230. The plurality of isolation zones 230 are arranged in parallel with each other. By arranging the plurality of transverse protrusions 210 in sequence and at intervals along the length direction of the second surface 200 to form the isolation zones 230, and arranging the plurality of isolation zones 230 in parallel with each other, the arrangement of the transverse protrusions 210 on the second surface 200 can be more orderly. Not only can more transverse protrusions 210 be arranged on the second surface 200, but also the stress during installation and use of the epoxy insulation board can be more uniform. The reliability of the epoxy insulation board is effectively improved.

[0030] In one embodiment, referring to Figure 1 and Figure 2 , the plurality of longitudinal protrusions 220 are arranged between adjacent two isolation zones 230, and each longitudinal protrusion 220 is perpendicular to the transverse protrusion 210 in the isolation zone 230. The two ends of each longitudinal protrusion 220 are respectively aligned with the central axes of the transverse protrusions 210 in the adjacent two isolation zones 230. The arrangement of the transverse protrusions 210 and the longitudinal protrusions 220 on the second surface 200 is more uniform and symmetrical, thereby further improving the reliability of the epoxy insulation board.

[0031] In one of the embodiments, referring to Figure 1 and Figure 2 The gap distance between the two adjacent transverse ribs 210, between the two adjacent longitudinal ribs 220, and between the two adjacent transverse ribs 210 and longitudinal ribs 220 is the same. By setting the same distance gap, the heat can be more evenly dispersed, thereby further improving the heat dissipation performance of the epoxy insulation plate.

[0032] In one of the embodiments, referring to Figure 1 and Figure 2 The epoxy insulation plate is further provided with a plurality of wiring channels 300, which avoid the transverse ribs 210 and the longitudinal ribs 220. The specific shape of the wiring channel 300 can be designed according to actual needs to meet different circuit connection requirements. It should be noted that in some special cases, the transverse ribs 210 or the longitudinal ribs 220 can also not be provided at the position of the wiring channel 300 to facilitate the wiring of the circuit.

[0033] Preferably, the wiring channel 300 is arranged between the two adjacent isolation regions 230, which can not only maintain high mechanical strength and stress uniformity, but also facilitate the wiring layout design of the circuit.

[0034] In one of the embodiments, referring to Figure 3 and Figure 3 The epoxy insulation plate is further provided with a plurality of hollow parts 400, which avoid the transverse ribs 210 and the longitudinal ribs 220. The hollow part 400 can be a regular circular hole, an elliptical hole, or a long strip-shaped hole. The hollow part 400 can also be set as a special-shaped hole according to the position of the transverse rib 210 and the longitudinal rib 220.

[0035] In one of the embodiments, the mounting structure is arranged on part of the hollow part 400, and the mounting structure is used to connect with the external equipment. The mounting structure can be a bolt and a nut. The epoxy insulation plate is fixed on the external equipment through the hole of the hollow part 400. In addition, a bolt groove can also be used instead. Furthermore, the epoxy insulation plate can also be installed by welding and pasting.

[0036] As shown in ​ , the utility model also provides a specific embodiment of a coil device.

[0037] A coil device, referring to ​ , the coil device comprises a coil 10 and the above-mentioned epoxy insulation plate 20, and the coil 10 is arranged on the first surface 100 of the epoxy insulation plate 20.

[0038] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them, and for those skilled in the art, the technical solutions recorded in the above embodiments can be modified, or some technical features therein can be replaced equivalently; and all these modifications and replacements shall belong to the protection scope of the present application.
