Abstract

(57) [Summary] [Purpose] To provide a fan motor mounting structure that requires no maintenance space and has a simple structure for maintenance and inspection. In a semiconductor device in which a fin mounted on a semiconductor element is cooled by a fan motor, a detachable bracket is provided on the semiconductor device, and a fan motor is attached to the bracket so that the fin can be cooled. Further, the bracket can be attached and detached from the front side within the mounting area of the semiconductor device by a fastening member.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is a fan motor mounting structure in which a fan motor part in a semiconductor device is removed by removing a fastening member from the front side of the semiconductor device when the fan motor of various semiconductor devices having a fan motor is maintained (replaced). It is about.

[0002]

[Prior art]

 As shown in FIG. 7, in various semiconductor devices having a conventional fan motor, electric parts that require cooling are fixed to the cooling fin 2 of FIG. 7, and the screw 10 for directly mounting the fan motor 4 on the cooling fin 2 is provided. 5, or as shown in FIG. 5, the wind tunnel 3 including cooling fins and the like that need to be cooled is configured, and the fan motor 4 is directly fixed to the wind tunnel 3 in the smallest space. . FIG. 6 shows a state in which the semiconductor device 1 of FIG. 5 is mounted on the control panel A, and the semiconductor device 1 shown in FIG. 5 is attached.

[0003]

[Problems to be solved by the device]

 Many of the fan motors that have been conventionally mounted on various semiconductor devices are thin type, and the direction of cooling air and the holes for mounting the fan motor are the same. It is fixed to the upper part or the lower part of the chassis, but in many cases, it is further housed in a cabinet such as a control panel. At the time of maintenance and inspection, as shown in FIG. 6, maintenance bases a and b are required above and below the semiconductor device 1 to allow work using a tool on the top or bottom of the semiconductor device, which is extremely structural. Not what I like. In view of the above-mentioned points of the present invention, it is an object of the present invention to provide a fan motor mounting structure that does not require such a maintenance space and can be maintained and inspected with a simple structure.

[0004]

[Means for Solving the Problems]

 In other words, the means for achieving that purpose is to provide a bracket that can be attached to and detached from this semiconductor device in a semiconductor device that is cooled by a fan motor mounted on a semiconductor element, and to cool the fins on this bracket. The fan motor is attached and the bracket can be attached / detached from the front side within the mounting area of the semiconductor device by means of fastening studs.

[Action]

 The operation will be described in combination with the embodiment described below.

 1 is a perspective view showing an embodiment of the present invention, FIG. 2 is a perspective view showing another embodiment of the present invention, FIG. 3 is a perspective view of a main body side to which the one shown in FIG. 1 or 2 is attached, FIG. 4 is a general assembly drawing showing an embodiment of the present invention. 1 to 4, a semiconductor device 1'comprises a main body 1 "and a bracket 5 or 5 ', and a removable bracket 5, 5'is provided on the main body 1". The fins 2 are cooled on the brackets 5, 5'. The fan motor 4'is attached so that the bracket 5 and 5'can be attached and detached from the front side within the attachment area of the semiconductor device 1'by means of a fastening member. That is, as shown in FIGS. 1 and 2, the brackets 5 and 5'of the present invention have guide claws 6 formed on the fixing surface side 1a of the main body 1 "of FIG. It is bent into a letter shape, and a hole 7 for a mounting screw or a U-shaped groove 7'is provided on the bent surface. As shown in FIG. 3, the fixing surface side of the main body 1 "of FIG. A fan motor 4'is provided by forming a hole 8 in 1a for fitting with a guide claw 6 and a screw hole 9 for fixing the brackets 5, 5'on the front side of the main body 1 ". For the fixed brackets 5 and 5 ', as shown in FIG. 4, the guide claws 6 are inserted into the holes 8 from the front side of the main body 1 ", and the brackets 5 and 5'are fitted in the mounting holes on the front side. The semiconductor device 1'is formed by being fixed. In the semiconductor device 1'constructed in this way, the brackets 5 and 5'can be removed by loosening the screws 10 from the front side of the control panel for maintenance and inspection. The motor 4'can be inspected.

[0006]

As described above, according to the present invention, it is possible to remove the screw to which the bracket is fixed, or to remove the bracket to which the fan motor is fixed by only loosening the screw. Therefore, even when a housing such as a control panel is stored, maintenance can be easily performed within the mounting area of the semiconductor device without being restricted in the upward and downward directions of the semiconductor device.
