The motor driving device is to be mounted to a control panel, and includes: a motor driving device main body; a radiator disposed to face a rear surface of the motor driving device main body; a fan motor unit being disposed above the radiator and being withdrawable through an area above the motor driving device main body; and a floor sheet member configured to be laid out along a withdrawal route of the fan motor unit in a process of withdrawing the fan motor unit.

According to various embodiments, a wireless charging device can comprise: a first housing, which includes a first surface facing a first direction and a second surface facing a second direction opposite to the first direction, and includes at least one hole; a second housing arranged on the second surface of the first housing in the second direction; a coil unit arranged between the first housing and the second housing and configured to transmit power to an external device; a shielding member arranged adjacent to the coil unit and including at least one hole; and a fan arranged adjacent to the coil unit and configured to rotate.

A power supply device includes an outer casing, a fan and a wire. Wherein the outer casing has four sides, wherein two adjacent ones of the four sides intersect, thus forming four corners. A central axis of which being parallel to an extending direction of the outer casing, and the fan being placed in the outer casing to divide the power supply device into a first part and a second part. The fan includes a fan frame having three positioning holes adjacent to any three of the four corners of the outer casing, wherein the fan frame has no positioning hole adjacent to the remaining corner of the four corners of the outer casing which forms a reserved space. The wire is connected to the second part from the first part of the power supply device through the reserved space.

A robot includes a first horizontal frame including a wheel and a motor for driving; a second horizontal frame which is spaced above the first horizontal frame and on which the control box is seated; a third horizontal frame which is spaced above the second horizontal frame and on which a sensor for autonomous driving is disposed; and a plurality of vertical frames which are spaced apart from each other on an upper surface of the second horizontal frame and connect the second horizontal frame and the third horizontal frame, in which the control box is provided so as to be capable of being drawn out inside the second horizontal frame through between two neighboring vertical frames.

A lighting device capable of suppressing an excessive temperature rise of a light emission section even when a fan is incapable of normal rotation. The light emission section emits light for illuminating an object. The fan cools the light emission section. A motor driving section drives the fan for rotation. A strobe microcomputer determines whether or not the motor driving section is abnormal, and controls a light emission interval of the light emission section in continuous light emission, based a result of the determination.

An actuator usable in a cooling system is described. The actuator includes an anchored region and a cantilevered arm. The cantilevered arm extends outward from the anchored region. The cantilevered arm includes a step region, an extension region and an outer region. The step region extends outward from the anchored region and has a step thickness. The extension region extends outward from the step region and has an extension thickness less than the step thickness. The outer region extends outward from the extension region and has an outer thickness greater than the extension thickness.

An electronic apparatus includes: a board accommodating portion that accommodates a board in a horizontally placed state, the board accommodating portion provided inside a housing; an intake opening provided in a right side plate of the housing and communicating with the board accommodating portion; an exhaust opening provided in a rear plate of the housing; a cooling fan provided in such a way as to face the exhaust opening; and a backboard that is a partition between the board accommodating portion and a fan accommodating portion that accommodates the cooling fan, in which a left side portion and a right side portion of the backboard have a left side vent and a right side vent through which the board accommodating portion and the fan accommodating portion communicate with each other.

A power supply system for a computer system having a fan module that protects the power supply system from backflow from the fan module is disclosed. A power supply unit has an internal fan emitting an airflow from one end of the power supply unit. The power supply unit is mountable next to the fan module. The power supply system is mountable in proximity to an air baffle that diverts the airflow generated by the internal fan. An air tunnel is located on one side of the power supply unit. The air tunnel has an opening on one end for receiving the airflow diverted by the air baffle from the internal fan. The air tunnel has an opposite end in proximity to a second opening to divert the received airflow under the power supply unit.

An electronics equipment cabinet includes one or more cabinet walls defining an interior enclosure space for housing electronic equipment and an air management box coupled to an interior surface of one of the one or more cabinet walls. The air management box includes a wall and a plurality of plates detachably coupled to the wall. The plates include a first plate having one or more perforations defining a first perforation pattern and a second plate having one or more perforations defining a second perforation pattern to control the direction and/or volume of airflow to the electronic equipment in the interior enclosure space or from the electronic equipment in the interior enclosure space to the air management box. The first perforation pattern is different than the second perforation pattern. Other example electronics equipment cabinets, electronics equipment cabinet kits, and methods of controlling airflow in electronic equipment cabinets are also disclosed.
