[0021] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, a multifunctional radiator for a photovoltaic inverter of the present invention comprises a photovoltaic inverter 1 and a radiator, wherein the radiator comprises a heat conducting plate 10, a plurality of heat dissipating fins 2 and a heat dissipating clamping piece 4, wherein the plurality of heat dissipating fins 2 are evenly arranged and mounted on the heat conducting plate 10, and the photovoltaic inverter 1 is placed on the surface of the heat conducting plate 10, and a plurality of limiting plates 5 are mounted on both sides of the photovoltaic inverter 1, and the limiting plates 5 are arranged in groups of two, and a limiting channel is formed between each group of limiting plates 5, and a fixing sleeve 3 is provided at both ends of the heat dissipating fins 2 facing the limiting channel, and one end of the heat dissipating clamping piece 4 is mounted on the fixing sleeve 3, and the other end passes through the limiting channel and is bent inward to form a limiting portion, and the limiting portion is set in conflict with the top surface of the photovoltaic inverter 1;

[0022] The materials of the heat conducting plate and the heat dissipation clamping sheet are the same as those of the heat dissipation fins, thereby ensuring the efficiency of heat conduction.

[0023] In this embodiment, connecting grooves are provided on the outer end faces of the fixing sleeves 3, and a fixing plate 7 is inserted into the connecting grooves on each side. A horizontal plate 8 is installed at one end of the multiple fixing plates 7, and a bearing is embedded in the center of the horizontal plate 8. Screw holes are provided on the inner ring of the heat dissipating fins 2 on one side facing the bearing, and a hand bolt 9 is installed in the inner ring of the bearing, and one end of the hand bolt 9 is threadedly connected to the screw hole.

[0024] In this embodiment, a fixing seat 6 is installed on the outermost heat dissipating blades 2. The fixing seat 6 is arranged in an "L" shape. A plurality of straight slots are provided on the fixing plate 7. Bolts can pass through the support opening to fix the fixing seat on any wall.

[0025] In this embodiment, the cross-sections of the fixing plate 7 and the connecting groove are both arranged in a trapezoidal structure, so that the fixing plate can be plugged into the fixing sleeve, thereby increasing the stability after the sliding connection.

[0026] In this embodiment, the inner side surfaces of the heat dissipation clamping pieces 4 are arranged to contact the side surfaces of the photovoltaic inverter 1 , so that the heat dissipation clamping pieces can exert a clamping force on the photovoltaic inverter.

[0027] In this embodiment, a plurality of air holes are provided on the fixing plate 7 so that the outside air can pass through the air holes and enter between the heat dissipation blades to ensure the air circulation effect.

[0028] During installation, place the photovoltaic inverter on the heat conducting plate so that it can fully contact the heat conducting plate. Then put the fixing sleeve on both ends of the corresponding heat dissipation fins. As the fixing sleeve moves inward, the vertical section of the heat dissipation clamping piece can enter the limit channel, and the limit part can move to the top surface of the photovoltaic inverter, thus completing the full-scale positioning of the photovoltaic inverter.

[0029] After the above is completed, insert the fixing plate into the connection groove on each side. The fixing sleeve can be synchronously and fully moved inward through the fixing plate and the cross plate until the inner side of the heat dissipation clamping plate contacts the side of the photovoltaic inverter. The photovoltaic inverter can be clamped to ensure the stability of the installation. The hand-tightening bolts can be threaded into the screw holes to ensure the firmness of the fixing plate after insertion.

[0030] It can be seen from the rise that the heat dissipation clamping sheet can not only increase the contact area with the air but also complete the clamping and fixing of the photovoltaic inverter, thereby increasing the functionality. Moreover, this clamping method eliminates the need to install an additional fixing structure for the photovoltaic inverter.
