Description

  The present invention relates to a control panel device that houses a power source and a heating element such as an input / output device (IO card) in the panel.

  The control panel device is configured by housing electronic devices such as a power supply device and an IO card for controlling machines and electrical devices in a housing.

  When such a control panel device is placed in an environment where dustproof and drip-proof properties are required, the power supply device and the IO card are placed in a highly airtight casing with a dustproof and dripproof structure. Since it is housed, the temperature in the housing rises due to heat generated from the power supply device, which may adversely affect the IO card and the like.

  In order to avoid this, there is a technique of attaching a heat exchanger as a cooling device to the control panel device. As an example, there is a control panel device 101 shown in FIG. 6A is a rear view of the control panel device 101, and FIG. 6B is a side sectional view.

  In the control panel device 101 of FIG. 6, a control unit 106 in which an IO card 105 is inserted and a power supply device 107 are attached to a unit fixing column bracket 108 and housed in a housing 102 having a front door 103. Yes.

  A heat exchanger 104 is attached as a cooling device to the back surface of the casing 102, and the heat exchanger 104 operates when the temperature rise in the casing 102 is significant due to heat generated from the power supply device 107 and the like. As a result, the inside of the control panel device 101 is cooled.

  However, as described above, the configuration in which the heat exchanger is attached to the casing of the control panel device leads to an increase in manufacturing cost and also requires maintenance of the heat exchanger and the management becomes complicated. .

  Further, the heat exchanger described above is intended for cooling the entire inside of the control panel device, and the power supply device with a large amount of heat generation is not directly targeted for cooling, so there is a problem that the cooling efficiency is lowered. It was.

  In addition, a space for installation is required to install the heat exchanger, which leads to an increase in the size of the entire control panel device.

FIG. 1A is a front view of a state in which the front door of the control panel device 1A according to the present embodiment is opened, and FIG. 1B is a top sectional view of the state in which the front door of the control panel device 1A is closed.

  The control panel device 1A according to the present embodiment is a horizontally long wall-mounted control panel device, and includes a housing 2A having a front surface opened by a metal plate and formed in a hollow shape, and a front for opening and closing the opening portion of the housing 2A. The door 3A is provided.

  In the housing 2A, the internal space is divided into two left and right spaces, a first space 21A and a second space 22A, by a partition plate 4A installed in the vertical direction.

  In the first space 21 </ b> A, a control unit 6 in which an input / output device (IO card) 5 is installed is housed and installed on the back surface of the housing 2. A printed circuit board (not shown), which is a heating element, is mounted on the IO card 5, but this heat generation amount is sufficiently smaller than that of the power supply device 7 described later.

  Further, the power supply device 7 is housed and installed in the other second space 22A. The power supply device 7 is a heating element that generates a large amount of heat.

  Although the number of control units 6 accommodated in the housing 2A can be arbitrarily changed, FIG. 1 shows a case where four control units 6 are accommodated.

  Moreover, the power supply device 7 is attached to the back surface in the housing 2A by an insulating heat conductive material 8 that is electrically insulated and has high thermal conductivity.

  Further, a hole (not shown) for venting outside air is provided in the bottom surface of the first space 21A of the housing 2A, and as shown in FIG. 2, the hole is covered from the inside of the housing 2A. In addition, a first vent plug 9A is attached, and a hole (not shown) is provided on the upper surface of the second space 22A of the housing 2A for venting outside air, and this hole is provided outside the housing 2A. A second vent plug 10 </ b> A is attached so as to cover.

  As shown in FIG. 3, the vent plugs 9 </ b> A and 10 </ b> A include an outer frame 11 having a plurality of vent holes 111, a waterproof breathable membrane 12 housed in the outer frame 11, and the waterproof breathable membrane 12. It is composed of a packing 13 that covers and fixes to the outer frame 11 and reinforces the waterproof breathable membrane 12 to prevent breakage.

  This waterproof breathable membrane 12 is formed of a microporous film provided with a large number of micropores for ensuring air permeability and waterproofness. The packing 13 is provided with a rough hole for allowing ventilation.

Is possible.

  At this time, since the fan 14A is installed at a position where the air blown from the first space 21A to the second space 22A directly hits the power supply device 7, the cooling efficiency of the power supply device 7 is further increased.

  In addition, since the waterproof air-permeable membrane 12 is provided in the intake vent plug 9A, the inside of the control panel device 1A is secured to be dustproof and waterproof even if the outside air is inhaled. Further, since the exhaust vent plug 10A is similarly provided with the waterproof breathable membrane 12, even when the fan 14A is not operating, the insertion of dust and water droplets into the control panel device 1A from the outside is prevented. be able to.

  The power supply device 7 is attached to the housing 2A by an insulating heat conductive material 8 that is electrically insulated and has high thermal conductivity. Since the housing 2A is formed of a metal plate, the power supply device 7 is emitted from the power supply device 7. Heat is also radiated to the outside from the insulating heat conductive material 8 and the housing 2A.

  According to the present embodiment described above, an IO card and a power supply device can be efficiently installed with a simple configuration in a horizontally long wall-mounted control panel device without adding a large and costly device such as a heat exchanger. Can be cooled.
