[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0030] Please see Figures 1-4 In this invention: a photovoltaic transformer with integrated grounding transformer includes a housing 1, a main body 2 installed inside the housing 1, two cavities 3 opened on the housing 1, two cooling chips 4 installed on the inner walls of the two cavities 3, the heat dissipation ends of the four cooling chips 4 all penetrate and extend to the outside of the housing 1, four square cavities 5 opened on the housing 1, heat dissipation pipes 6 arranged at equal intervals are fixedly connected to the inner walls of the two cavities 3, the two ends of the two sets of heat dissipation pipes 6 penetrate the housing 1 and extend into the four square cavities 5 respectively, the inner walls of the four square cavities 5 are connected to conduits 7 arranged at equal intervals, one end of the conduit 7 penetrates and extends into the interior of the housing 1, a fan 8 is installed on the inner wall of the conduit 7, and the back of the housing 1 is connected to conduits 9 arranged at equal intervals.

[0031] In this invention, during operation, the housing 1 is used to install the main body 2, which is a photovoltaic transformer with an integrated grounding transformer. After the main body 2 generates heat during operation, the user turns on the cooling element 4 and the fan 8. After the cooling element 4 is turned on, its cooling end will cool the refrigerant in the cavity 3. Multiple fans 8 at the bottom will draw the hot air inside the housing 1 into the square cavity 5 and input it into the heat dissipation pipe 6. Multiple fans 8 at the top will draw the air in the heat dissipation pipe 6 back into the housing 1, thus completing the air circulation. During the circulation process, the air will continuously exchange heat with the coolant through the heat dissipation pipe 6. This lowers the air temperature, and the cooled air entering the enclosure 1 dissipates heat from the main body 2, bringing it to its normal operating temperature. Throughout the heat dissipation process, the enclosure 1 remains sealed, effectively preventing external moisture and dust from entering. This improves the dust and moisture resistance of the device, enhances the stability of the main body 2 during operation, and the sealed enclosure 1 also effectively insulates the main body 2 from noise, reducing the impact of noise generated by the main body 2 on nearby personnel and improving the practicality of the device.

[0032] Please see Figure 2 The inner bottom wall of the box 1 is fixedly connected to a sound insulation layer 10, which is sleeved on the conduit 7.

[0033] In this invention, the sound insulation layer 10 can improve the sound insulation effect of the enclosure 1, thereby improving the practicality of the device.

[0034] Please see Figure 2 The inner wall of the housing 1 is equipped with four dampers 11, and the tops of the four dampers 11 are fixedly connected to the main body 2.

[0035] In this invention, the damper 11 can buffer the body 2, reduce the noise generated by the vibration of the body 2, and thus improve the practicality of the device.

[0036] Please see Figure 3 and 2 The cooling end of the cooling chip 4 is fixedly connected to a heat-conducting plate 12 arranged at equal intervals, and the heat-conducting plate 12 is sleeved on two heat dissipation pipes 6.

[0037] In this invention, the heat-conducting plate 12 can improve the cooling effect of the cooling chip 4 on the coolant and the cooling effect on the heat dissipation pipe 6, thereby improving the practicality of the device.

[0038] Please see Figure 2 and 3 Among them, a ring of heat-conducting rods 13 are fixedly connected to the heat-conducting plate 12, and one end of the heat-conducting rod 13 penetrates and extends into the interior of the heat dissipation pipe 6.

[0039] In this invention, the heat-conducting rod 13 can improve the cooling effect of the heat-conducting plate 12 on the air in the heat dissipation pipe 6, thereby improving the heat dissipation effect on the body 2.

[0040] Please see Figure 2 The inner wall of the conduit 9 is fitted with an airbag 14, and the outer side of the airbag 14 is connected to a gas filling pipe 15. The top end of the gas filling pipe 15 passes through and extends to the outer side of the conduit 9, and a valve is installed at the top end of the gas filling pipe 15.

[0041] In this invention, the conduit 9 is used for the entry and exit of the wiring in the main body 2. After the wiring is set up, the user inflates the airbag 14. The airbag 14 will expand and fit tightly against the wiring, thereby sealing the gap between the wiring and the conduit 9, thus improving the practicality of the device.

[0042] Please see Figure 2 Among them: the bottom of the box 1 is fixedly connected with four threaded sleeves 16, and the inner walls of the four threaded sleeves 16 are all threadedly connected with bases 17.

[0043] In this invention, the cooperation between the base 17 and the threaded sleeve 16 can support the box 1, and the distance between the base 17 and the box 1 can be adjusted by rotating the base 17, thereby leveling the box 1 and making it suitable for use on uneven ground, thus improving the practicality of the device.

[0044] Please see Figure 2 The base 17 has an anti-slip pad 18 fixedly connected to its bottom, and the anti-slip pad 18 is a rubber layer.

[0045] In this invention, the anti-slip pad 18 can increase the friction between the base 17 and the ground, thereby improving the stability of the support for the box 1.

[0046] The above are merely preferred embodiments of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
