を行う。2. Description of the Related Art Many control panels for machine tools and the like have a sealed structure for preventing dust and water. Due to this sealed structure, power elements such as drive motors and the like provided inside the control panel are installed. There is a problem that the temperature inside the control panel rises due to the heat generation, and the machine tool cannot be driven stably. Therefore,
Conventionally, in order to suppress the temperature rise inside the control panel during driving, a heat exchanger or heat pump heat exchange device for heat exchange is attached to the door of the control panel or the top surface of the control panel to control the temperature inside the control panel. Controls the rise. That is, for example, the heat exchanger suppresses an increase in the temperature of the control panel by exchanging heat between the inside and the outside in an aluminum container that separates the inside and the outside of the control panel. The heat pump circulates a substance having a large heat capacity through heat exchangers inside and outside the control panel to perform heat exchange.

装置を提供することを目的とする。However, in order to mount the above heat exchanger or heat pump heat exchange device, it is necessary to provide an opening in the sheet metal of the control panel, and to prevent dust and water proofing of the control panel. , It is necessary to seal the opening. The effect of this sealing has a problem that there is a work mistake at the time of installation and it is reduced by long-term use. Further, since the heat exchange device is generally expensive, there is a problem that the cost of the control device becomes high. The present invention is to solve the above-mentioned problems, without using a heat exchange device such as a heat exchanger or a heat pump, heat is exchanged between the inside and outside of the control panel with a simple configuration, and the temperature inside the control panel is increased. An object of the present invention is to provide a control panel cooling device that can be suppressed and can reduce the cost of the entire machine tool.

The blower fan 2 for transmitting the heat generated inside the control panel to the top plate 1a of the control panel 1 is inside the control panel 1, and the cooling fan 3 for dissipating the heat of the top plate 1a is outside the control panel 1. Each is provided. The internal air becomes hot due to the heat generated inside the control panel 1, and this hot air, especially the air staying above the inside of the control panel 1, is blown by the blower fan 2 to the top plate 1a.
Sent to. As a result, the heat inside is exchanged with the top plate 1a. Further, the top plate 1a is air-cooled by a cooling fan 3 provided outside thereof. Thus, the heat generated inside the control panel 1 is released to the outside of the panel.

ンにも寄与する。As described above, since the control panel cooling device can perform heat exchange with the control panel 1 having a closed structure, the control panel cooling device can be installed more easily than when a conventional heat exchanger or heat pump heat exchange device is used. Since it is not necessary to seal the opening, labor for manufacturing can be saved, and the inside of the panel can be cooled while keeping dustproof and waterproof, which in turn contributes to cost reduction.

In this embodiment, in addition to the configuration of the above embodiment, the regenerative resistor 4 of the spindle motor of the machine tool is arranged at a position slightly separated from the outer surface of the top plate 1a. The regenerative resistor 4 is a resistor that converts kinetic energy of the spindle of the machine tool into electrical energy when the spindle motor is stopped by applying an electric brake. Since the regenerative resistor 4 generates heat during braking, arranging it in the control panel promotes temperature rise. Therefore, the regenerative resistor 4 is provided above the top plate 1a so that the cooling fan 3 air-cools the outer surface of the top plate 1a and the regenerative resistor 4 as well. As a result, the amount of heat generated inside the control panel 1 can be reduced, and the regenerative resistor 4 can be air-cooled by the cooling fan 3, so that the capacity of the regenerative resistor 4 can be reduced.

It is possible to prevent the cooling effect of the top plate 1a from being impaired by sending the outside air to the lower surface of the top plate 1a.
