Description

  The present invention relates to an electrical housing that can provide a configuration that secures a cooling channel without increasing the number of components.

  Conventionally, an electrical board mounted on an image forming apparatus or the like has a special cooling structure such that it is arranged using a space of a machine and a fan is attached to each of them, if necessary. There wasn't.

  Further, even when the electrical system is collected unilaterally, the cooling structure has a structure in which the entire electrical system is performed as a unit.

Here, as a structure for cooling the temperature inside a predetermined casing, a Peltier element is brought into contact with the inside of the sealed casing in which the polygon unit is arranged in order to realize improvement in cooling efficiency around the polygon unit at a relatively low cost. A technique for disposing has been proposed (see, for example, Patent Document 1).

  However, the conventional example described above has the following problems.

  With the recent miniaturization and speeding up of machines, the electrical boards have become larger and have higher heat generation. For this reason, the layout of electrical systems has become difficult to configure using conventional mechanical gaps. The cooling structure of this type also has a problem that it is difficult to deal with individually because of recent demands for noise reduction and energy saving. Further, in the case of a single pole concentration, there is a problem that it is difficult to reduce the cooling capacity or noise in the cooling structure in which the entire electrical system is one unit.

  Accordingly, an object of the present invention is to provide an electrical housing that can secure an installation location for electrical components, and can secure a cooling channel without increasing the number of components.

  The invention according to claim 1 is an electrical equipment case having a mechanism for concentrating and storing at least one of an electrical equipment substrate, a hard disk, and a power source with heat generation, wherein an air cooling flow path inside the housing is provided. It is an electrical equipment case characterized in that it is configured by arrangement of stored items inside the case.

  According to a second aspect of the present invention, in the electrical housing according to the first aspect, the stored items inside the housing are arranged according to the operation timing.

  According to a third aspect of the present invention, in the electrical casing according to the second aspect, the fan for forcibly cooling the inside of the casing forcibly cools each flow path configured according to the operation timing of the stored items.

  According to a fourth aspect of the present invention, there is provided the electrical equipment casing according to any one of the first to third aspects, wherein the heat of the machine main body in which the casing is incorporated is drawn into the casing.

  According to a fifth aspect of the present invention, in the electrical housing according to the fourth aspect, the configuration in which the heat of the machine body is drawn into the interior of the electrical machine case is distinguished by the position where the machine body is incorporated. Be controlled.

  According to the electrical equipment casing of the present invention, it is possible to secure an installation location for electrical components and secure a cooling flow path without increasing the number of components.

  A configuration of an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view of an electrical housing that collects and stores electronic boards, hard disks, and power sources that generate heat. In the electrical housing, electrical boards 1 to 5 and an HDD (Hard Disk Drive) 6 are installed.

  FIG. 2 is a front view of the electrical housing.

  Conventionally, the arrangement of the electrical boards has been oriented in the direction facing the operator (in the direction of arrow 7) as shown in FIG. 6 in order to ensure the convenience of work when the connector is inserted into the board. However, in this case, when two cooling channels are provided in the electrical housing, a sheet metal or the like for newly configuring the channels has to be added.

  In the present embodiment, as shown in FIG. 1, the interior of the electrical housing is partitioned by the electrical substrate 3, and left and right flow paths are configured.

  At this time, the connector on the electrical board 3 is basically used only for connection between the boards, that is, for connection between the electrical board 3 and the electrical board 1, the electrical board 2, the electrical board 4, or the electrical board 5. No connection connector is installed.

  The configuration of the first embodiment of the present invention will be described with reference to the drawings.

  In the two-channel flow paths configured as shown in FIG. 1, the operation timings of the electrical components installed on the flow paths in each flow path are combined.

  As an example of this configuration, there is a configuration in which machine control components are arranged on the left channel in FIG. 2 and data processing components are arranged on the right side. Here, in the case of an image forming apparatus or the like, when the machine enters the energy saving mode, the operation of the machine control unit stops and only the data processing unit operates.

  According to the above embodiment, the temperature in the flow path differs between the left and right flow paths, so that it is possible to independently take measures against heat of the electrical components on the flow paths.

  The configuration of the second embodiment of the present invention will be described with reference to the drawings.

  When forced cooling is performed in two channels as in the first embodiment, as shown in FIG. 3, the fan 8 is installed for each channel, so that the operation of the fan depends on the situation of each channel. It is the structure which controls.

  According to the above embodiment, in the case of an image forming apparatus or the like, in the energy saving mode, the fan on the flow path constituting the machine control unit is stopped and only the fan on the flow path constituting the data processing unit is operated. Well, quiet and energy saving can be realized.

  The configuration of the third embodiment of the present invention will be described with reference to the drawings.

  As shown in FIG. 4, a heat intake port 9 from the machine main body side is provided on the side surface of the machine main body side in which the electrical housing is incorporated.

  According to the above-described embodiment, it is possible to cool the machine main body without adding a new fan.

  The configuration of the fourth embodiment of the present invention will be described with reference to the drawings.

  As shown in FIG. 5, heat intake ports 10 and 11 from the machine main body side in which the electrical housing is incorporated are provided for each of the left and right flow paths. Thereby, it becomes the structure which changes the cooling timing of the machine main body side according to a place.

  According to the above embodiment, in the case of an image forming apparatus or the like, the fixing unit that needs to be cooled during the machine operation and needs to be kept warm after the machine is stopped is connected to the flow that forms the machine control unit of the electrical housing. By installing at the rear of the road, the needs of the fixing unit can be satisfied.

  The above-described embodiments and examples are preferred embodiments of the present invention, and various modifications can be made without departing from the scope of the present invention. For example, three or more heat intake ports from the machine body side may be provided.
