A charging cabinet is disclosed having a frame, a center vertical member, wherein the center vertical member includes a lock plate, a plurality of stock chargers, an exhaust system, configured to vent heat from the charging cabinet to cool the at least one battery, a heater, configured to warm the at least one battery, a pair of duplex receptacles, a pass-thru connector recess box, wherein the pass-thru connector recess box is angled downward, a pass-thru connector mount box, wherein the pass-thru connector mount box is angled upward, an inlet connector recess box, wherein the inlet connector recess box is angled downward, and an inlet connector mount box, wherein the inlet connector mount box is angled upward.

A cooling system includes an evaporator associated with a heat source. A condenser is located at a higher elevation than the evaporator. A heat pipe structure fluidly connects the evaporator with the condenser. A fan forces air through the condenser. A working fluid is in the evaporator so as to be heated to a vapor state, with the heat pipe structure transferring the vapor to the condenser and passively returning condensed working fluid back to the evaporator for cooling of the heat source. A plurality of thermoelectric generators is associated with the condenser and converts heat, obtained from the working fluid in the vapor state, to electrical energy to power the fan absent an external power source. The thermoelectric generators provide the electrical energy to the fan so that a rotational speed of the fan is automatically self-regulating to either increase or decrease based on a varying heat load.

A mounting rail is provided that includes a DIN rail and one or more heating cable channels. A channel defined by the DIN rail may include one of the heating cable channels. Heating cables may be installed in the heating cable channels using adhesive and/or heat transfer material to form an electronics heating module. The heating cables may be self-regulating heating cables. The mounting rail may include multiple heat transfer fins that transfer heat generated by the heating cables to environment surrounding the mounting rail. A terminal block may be mounted on the DIN rail and may supply electric power to the heating cables.

A technology downsizing a control panel unit is provided. The control panel unit for a machine tool comprises a casing, a duct, and a fan. The casing has an openable door. A control device is arranged in an internal space, which is closed when the door is closed. The duct has a groove and a ventilation opening. The groove is closed at a closed end and open to the internal space at an open end. The ventilation opening connects the groove with the internal space in a position nearer the closed end than the open end. The duct is fixed to an inner wall of the casing in such manner as the groove faces the inner wall. The fan is mounted on the ventilation opening. The air in the internal space is taken into the groove enclosed by the inner wall and the duct by the operation of the fan.

A method for controlling the temperature of a switchgear cabinet for medium- or high-voltage switching devices. The switchgear cabinet is heated with anti-condensation heating to prevent a condensation of air moisture on components that are located in the inner volume of the switchgear cabinet. The method is particularly environmentally friendly and sustainable. There is also described a system for carrying out such a method.

The present disclosure relates to an arc ventilation system of a distributing board, and more particularly, to an arc ventilation system of a distributing board to minimize an arc flowing forward to prevent damage. In the arc ventilation system of a distributing board in which a plurality of compartments are provided, a first compartment accommodating an electric power device which can be drawn in or out, among the plurality of compartments, comprises an arc blocking part blocking a space between the electric power device and the first compartment at an operation position of the electric power device.

The present disclosure relates to a distribution board ventilation system including a circulation chamber serving as a passage for air circulation and arc discharge; a first compartment provided at one surface of the circulation chamber; a second compartment which is adjacent to the first compartment and provided at the other surface adjacent to the one surface of the circulation chamber; a first discharge door mounted on the one surface of the circulation chamber to open the first compartment; a second discharge door mounted on the other surface of the circulation chamber to open the second compartment; and a linking means which is mounted between the first discharge door and the second discharge door and ensures that the open states of the first discharge door and the second discharge door are mutually exclusive.

A system, for measurement of temperatures and detection of faults of parallel transformers in a DDC enclosure, that includes a first transformer and a second transformer arranged in a parallel configuration that deliver power to components of a building management system (BMS). The system also includes a direct digital control (DDC) circuit that controls power delivered through the first and the second transformers to the components of the building management system (BMS). The system further includes a first temperature sensor, operationally connected to the DDC circuit, which measures the temperature of the first transformer. Furthermore, the system includes a second temperature sensor, operationally connected to the DDC circuit, which measures the temperature of the second transformer. The DDC circuit determines a difference between the first temperature and the second temperature to predict a fault in the first transformer or the second transformer.

A system for managing temperature, that can be adapted to an electrical enclosure, the electrical enclosure delimiting a first volume, the system comprising: a first chamber delimiting a closed second volume and a tank housed in the first chamber and delimiting a closed third volume inside the first chamber, first air transfer means arranged between a first air inlet/outlet connected to the second volume and a second air inlet/outlet intended to be connected to the first volume, second air transfer means arranged between a third air inlet/outlet connected to the third volume and a fourth air inlet/outlet intended to be connected to the first volume, and a control and processing unit intended to apply a mode of operation of the system.

The arrangement includes a pressure relief hatch for closing an opening in a wall in an electric cabinet, which. includes a body having an outer surface, an opposite inner surface, an outer perimeter, and a thickness. The body includes a centre portion with a first thickness, an intermediate portion with a second thickness, and an outer portion with a third thickness. The first thickness is greater than the third thickness and the second thickness decreases in a radially outward direction from the first thickness to the third thickness. A spring keeps the pressure relief hatch in a closed position in the opening during normal operation of the electric cabinet.
