Abstract
The utility model relates to a modular structure of a frequency conversion power source heat radiation fan. The modular structure is composed of a plurality of fans and a rectangular installation plate. The utility model assembles a plurality of fans through an installation plate. A modular structure is formed thereby leading to that a plurality of fans can be installed in a time and the respective installation is not required. At the same time the lower end of the modular structure is provided with an installation alignment pin which can be inserted into the pin hole on the baseboard for locating. The difficulty for installing and locating is reduced, and at the same time the upper end of the installation plate is provided with an exterior fold edge which is used for the installation and fixation of the module. The fixing operation is executed at the upper end of the cabinet. The problem of inconvenient installation operation in narrow space is settled. Therefore, the modular structure has the characteristic of quick and convenient installation.
Description
Technical field
The utility model relates to a kind of mounting structure of variable-frequency power sources cooling fan, relates in particular to the modularization mounting structure of variable-frequency power sources cooling fan.
Background technique
In prior art, the three-phase converter module device in the variable-frequency power sources need be concentrated heat radiation, generally is that a phase power cell is provided with a blower fan, by blower fan to the power cell heat radiation of drying.Common fan installing structure is equipped with a blower fan 2 respectively in a side of three power 6 shown in Fig. 6～8, blower fan 2 correspondences are installed on the L shaped mounting plate 10, and then mounting plate 10 are fixed on the base plate of cabinet 5.This mounting structure makes the installation of blower fan quick inadequately and convenient, this is because three blower fans are separation structures, can not once assemble, fitting operation need be carried out three times repeatedly, moreover, installing space in the cabinet is narrow and small, installs and fixes operation all at the chassis backplane place, makes the operation of screw location and last bolt all comparatively difficult.
The model utility content
The purpose of this utility model is at the shortcoming in the prior art, and a kind of modular construction of variable-frequency power sources cooling fan is provided, and makes the installation of cooling fan quick and convenient.
For achieving the above object, the technical solution of the utility model is as follows:
It has a plurality of blower fans, it improves structure: it also has a rectangle mounting plate, on the plate face of this rectangle mounting plate, be provided with the exhaust outlet of a plurality of blower fans, Bian Chu is provided with interior flanging in the lower end of this rectangle mounting plate, the place, limit is provided with an outer flanging in the top, also is fixedly connected with locating stud in described on the flanging, is provided with mounting hole outside described on the flanging, described a plurality of blower fan is arranged on the mounting plate, and fixes by fastening piece.
Described blower fan is three blower fans, and laterally is arranged side by side on the rectangle mounting plate.
Exhaust outlet on the described rectangle mounting plate plate face is a circular port.
By technique scheme as can be seen, the utility model fits together a plurality of blower fans by a mounting plate, has formed a modular construction, thereby can make the disposable installation of a plurality of blower fans, need not install respectively; Simultaneously, be provided with the installing and locating pin, can insert when mounted in the pin-and-hole on the base plate and position in this modular structure lower end, reduced the difficulty of installing and locating, moreover, mounting plate be fixed in cabinet upper end, avoided having solved the unhandy problem of small space in the operation of case inner bottom part.Therefore, the utlity model has and install fast and characteristics easily.
