As shown in fig. 1-2, an dc-to-ac converter with split type fan module, including dc-to-ac converter main part 1 and install the fan module in dc-to-ac converter main part 1, the fan module includes fan mounting panel 2, is equipped with a plurality of fan installing ports 3 on the fan mounting panel 2, installs a fan 4 in every fan installing port 3, and the one end of fan mounting panel 2 is equipped with a plurality of direction picture peg 5, and the handle 6 is installed to the other end of fan mounting panel 2, is equipped with a plurality of guiding holes 7 on the dc-to-ac converter main part 1, and direction picture peg 5 and guiding hole 7 one-to-one, during direction picture peg 5 inserted corresponding direction jack 7, be connected with dc-to-ac converter main part 1 through a plurality of screws around the fan mounting panel 2. After corresponding screws are disassembled, the fan module is pulled away from the inverter main body 1 from one direction, the guide inserting plate 5 is inserted into the corresponding guide inserting hole 7 during installation, and quick positioning is achieved between the fan installing plate 2 and the inverter main body 1. The last guiding hole 7 that has that sets up of dc-to-ac converter main part 1, this scheme adopts the mode that realizes quick direction under the condition that does not increase any unnecessary part, makes fan module and dc-to-ac converter main part 1 can be quick through this scheme, and is accurate, safe, reliable installation to do not increase the cost. Further, the both sides of fan mounting panel 2 are bent down and are formed board 8 of bending down, the upper end both sides of dc-to-ac converter main part 1 are pressed from both sides respectively and are bent down between the board 8, are equipped with a plurality of screw holes 9 on the board 8 of bending down, the both ends of fan mounting panel 2 are bent up respectively and are formed board 10 of bending up, go up handle 6 and install on the board 10 of bending on keeping away from direction picture peg 5. Two boards 8 of bending down form the slide rail, the fan module of easy to assemble. The mode that the fan module is supported by the thin wall is adopted by the inverter main body 1, the inverter main body 1 is in thin-wall contact with the installation surface of the fan module, and the thin wall can effectively reduce the contact area between the fan module and the inverter main body 1, so that the fan module is more smoothly pushed during installation and is more efficient in installation.

Furthermore, both sides of the fan mounting plate 2 are respectively connected with a side plate 11 through screws, the side plate 11 and the upper bending plate 10 enclose a protection frame, and the fan 4 is located in the protection frame. The protective frame has a protective effect on the fan 4 and prevents the fan 4 from being directly collided with in the moving process.
