[0003] The main body of VPX is typically cabinet-like or box-shaped, requiring heat dissipation during use. The required heat dissipation capacity varies depending on environmental factors. Therefore, we propose an extended structure for the VPX backplane to address these issues. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are: the extended structure of this VPX backplate not only realizes the extended heat dissipation function and the insulation and heat conduction function, but also realizes the protection and breathability function.

[0012] (1) By setting an extended heat dissipation structure, the present invention is beneficial in that: when the VPX is in use, a large amount of heat will be generated. During operation, the two sets of protective covers will slide inside the sliding groove at the front end of the back panel body, so that the magnetic blocks on the protective covers will make magnetic contact with the side metal blocks on both sides of the sliding groove.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 The present invention provides an embodiment of an extended structure for a VPX backplate, comprising a backplate body 8, a heat sink 5 at the front end of the backplate body 8, a cooling fan 6 installed at the front end of the backplate body 8, sliding grooves 3 at the top and bottom of the front end of the backplate body 8, a protective cover plate 2 inserted inside the sliding groove 3, a magnetic block 4 on the inner side of the front end of the protective cover plate 2, a rear limiting stop bar 9 on the outer side of the protective cover plate 2, and side metal blocks 1 on both sides of the sliding groove 3.

[0022] The protective cover 2 slides inside the sliding groove 3 at the front end of the back plate body 8. The protective cover 2 is provided in two sets. The protective cover 2 drives the magnetic block 4 to magnetically connect with the side metal block 1 on one side of the sliding groove 3. The protective cover 2 covers the heat sink 5 and the cooling fan 6 at the front end of the back plate body 8.

[0023] Specifically, such as Figure 1 and Figure 2 As shown, by setting up an extended heat dissipation structure, a large amount of heat is generated when the VPX is in use. During operation, the two sets of protective covers 2 slide inside the sliding groove 3 at the front end of the back panel body 8, so that the magnetic blocks 4 on the protective covers 2 make magnetic contact with the side metal blocks 1 on both sides of the sliding groove 3. Then, the heat sink 5 and the cooling fan 6 at the front end of the back panel body 8 are exposed, which accelerates the dissipation of the heat generated inside the VPX case, thereby realizing the extended heat dissipation function.

[0024] The rear end of the back plate body 8 is provided with a contact inner groove 11, the inside of the contact inner groove 11 is filled with a heat-conducting copper plate 10, and the heat-conducting copper plate 10 and the inner side of the contact inner groove 11 are coated with an insulating coating 12.

[0025] The heat-conducting copper plate 10 is embedded in the contact groove 11 opened inside the back plate body 8, and the insulating coating 12 is applied to the inner wall of the contact groove 11 and the surface of the heat-conducting copper plate 10 inside the contact groove 11.

[0026] Specifically, such as Figure 2 and Figure 3 As shown, by setting an insulating and heat-conducting structure, a contact groove 11 is provided in the back plate body 8 during use. After the contact groove 11 is filled with a heat-conducting copper plate 10, an insulating coating 12 is applied to the inside of the contact groove 11 at the rear end of the back plate body 8 and the outside of the heat-conducting copper plate 10. The heat-conducting copper plate 10 accelerates heat transfer, and the insulating coating 12 has insulation properties to increase the safety of the VPX circuit board in contact with the back plate body 8, thereby realizing the insulating and heat-conducting function.

[0027] The protective cover plate 2 has an inner groove 7 at its front end, an inner groove 13 on the inner side of the inner groove 7, and a rear ventilation groove 14 at its rear end.

[0028] The inner grooves 7 are evenly spaced at the front end of the protective cover plate 2, and the protective cover plate 2 is connected to the rear ventilation groove 14 at the rear end of the protective cover plate 2 through the inner groove 13 on the inner side of the inner grooves 7.

[0029] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, by setting up a protective and breathable structure, multiple sets of inner grooves 7 are opened at the front end of the protective cover plate 2 during use. An inner groove 13 is set inside the inner groove 7. The inner groove 13 inside the inner groove 7 is connected to the rear ventilation groove 14 at the rear end of the protective cover plate 2. The heat of the heat sink 5 and the heat dissipation fan 6 at the front end of the back plate body 8 can be discharged from the inner groove 7, thereby realizing the protective and breathable function.

[0030] Working Principle: This utility model uses a backplate body 8 on the VPX box to contact the circuit board inside the VPX box, and the circuit board to contact the heat-conducting copper plate 10 in the contact groove 11. An insulating coating 12 is applied to the inside of the contact groove 11 at the rear end of the backplate body 8 and the outside of the heat-conducting copper plate 10. The insulating coating 12 has insulation properties to increase the safety of the contact between the VPX circuit board and the backplate body 8. The contact between the circuit board and the heat-conducting copper plate 10 accelerates heat transfer, which is transferred to the heat sink 5 through the backplate body 8 and discharged from the inner groove 13 inside the inner groove 7 through the rear ventilation groove 14 at the rear end of the protective cover 2. If the heat is too high, the two sets of protective covers 2 can slide inside the sliding groove 3 at the front end of the backplate body 8, so that the magnetic blocks 4 on the protective covers 2 make magnetic contact with the side metal blocks 1 on both sides of the sliding groove 3. Then, the heat sink 5 and the cooling fan 6 at the front end of the backplate body 8 are exposed, and the cooling fan 6 is activated to accelerate the discharge of heat and dissipate the heat generated inside the VPX box.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
