Abstract
The utility model discloses an assembly structure of an inverting power supply device, which causes main exothermic components to be installed on a machine base behind a blower in series, and all the exothermic components are caused to be positioned on a cooling air duct between an air inlet and an air outlet to realize high efficient thermal design. The utility model is characterized in that an exhaust outlet is arranged in a back panel, an exhaust outlet of the blower is connected with the inner side of the exhaust outlet, the air inlet is arranged in the casing wall of a cover casing, and a main transformation component, a main transformer, a rectification component and a reactor are the main exothermic components and are installed on the base in series.
Description
The utility model relates to a kind of assembly structure of inverter power supply device, the particularly a kind of assembly structure of main heat generating components tandem in cooling air channel that makes inverter.
Have now and form casing by front and back two panels, base and cases, the main transformer that comprises blower fan and be fixedly mounted on the base changes the mainly inverter power supply device of heat generating components such as parts, main transformer, rectification part and reactor, its main heat generating components is partly or entirely assembling side by side, thereby make wherein that some is located at outside the cooling air channel of blower fan partially, cause the radiating effect of this part parts relatively poor, have influence on the safe and reliable of machine performance and component.
The purpose of this utility model is for overcoming the above-mentioned defective of prior art, realize the assembly structure that main heat generating components is provided with along blower fan cooling air channel tandem in inverter.
For realizing that the technical measures that the utility model purpose is taked are, on the rear board (1) of inverter power supply device, have exhaust outlet (2), the exhaust outlet of blower fan (3) is right after the exhaust outlet inboard of plate in the back, go up on the shell wall of locating near front panel (5) at the case (4) of inverter power supply device and to have air inlet (6), comprise that main transformer changes parts (7), main transformer (8), rectification part (9) and reactor heat generating components such as (10) and is installed on the base (11) between blower fan and the front panel by tandem.
Assembly structure of the present utility model is installed on the exhaust outlet and the cooling air channel between the air inlet of blower fan the equal tandem of main heat generating components of inverter power supply device, arbitrary part among them all is in the air-cooled heat dissipation environment, has realized the effect of high efficiency and heat radiation.
Below in conjunction with accompanying drawing and an embodiment the utility model is further elaborated.
Fig. 1 is the entity assembling schematic diagram of an embodiment of the utility model inverter power supply device.
Fig. 2 bows for the base assembling of an embodiment of the utility model inverter power supply device and shows schematic diagram.
1 is rear board among the figure, and 2 is exhaust outlet, and 3 is blower fan, and 4 is case, and 5 is front panel, and 6 is air inlet, and 7 for main transformer changes parts, and 8 is main transformer, and 9 is rectification part, and 10 is reactor, and 11 is base.
In this embodiment, be installed in the main heat generating components on the base (11) between blower fan (3) and the front panel (5) by tandem, its erection sequence is, after blower fan, change parts for main transformer, then the back is a main transformer, connecing is thereafter rectification part again, is reactor between rectification part and front panel.
Claims (2)
1, a kind of by two panels in front and back, base and case are formed casing, the main transformer that comprises blower fan and be fixedly mounted on the base changes parts, main transformer, rectification part and reactor are the inverter power supply device of main heat generating components, it is characterized in that, on described rear board, have exhaust outlet, the exhaust outlet of described blower fan is right after the inboard at described rear board exhaust outlet, have air inlet on the shell wall at the approaching described front panel place of described case, described main transformer changes parts, main transformer, to be main heat generating components be installed in above the described base between described blower fan and the described front panel by tandem for rectification part and reactor.
2, according to the described inverter power supply device of claim 1, it is characterized by, tandem is installed the erection sequence of described main heat generating components and is above the described described base between described blower fan and described front panel, after described blower fan, change parts for described main transformer, then the back is described main transformer, connecing is thereafter described rectification part again, is described reactor between described rectification part and described front panel.
