The present disclosure provides an electrical device using a cooling device, which includes a first box, a second box arranged on one side of the first box, and a power device arranged inside the first box. The cooling device is arranged inside the second box, and the cooling device includes a substrate evaporator, a first condenser and a pipe. The cooling device is configured to collect the heat inside the first box to the second box, that is, the substrate evaporator directly absorbs the heat generated by the high-power devices inside the first box. Moreover, the spoiler fan arranged inside the first box can disturb the air inside the first box, so that the spoiler fan and the first box evaporator cooperate to exchange heat in the air inside the first box.

A solar powered vehicle topper unit and systems and methods for the same are provided. A solar energy harvesting device is electrically connected to an electronic display within a housing. A support extends between the housing and the solar energy harvesting device such that a bottom surface of the solar energy harvesting device is located above, and spaced apart form, a top surface of the housing to secure the solar energy harvesting device in an elevated position. The solar energy harvesting device has a first footprint, and the housing has a second footprint which is smaller than the first footprint.

A heat dissipating system and a power cabinet are provided. The heat dissipating system includes a cabinet, a first circulating fan and a heat exchanger. The cabinet has an outer circulating air duct and a sealed inner circulating air duct. The air inlet and the air outlet connected to the outside are arranged in the outer circulating air duct, and the heat exchanger is arranged in the cabinet and configured to exchange heat between the inner circulating air duct and the outer circulating duct. The first circulating fan is arranged outside the air inlet of the outer circulating air duct or arranged inside the outer circulating air duct, and configured to supply air to the outer circulating air duct. The heat dissipation efficiency of the inner circulating air duct is improved.

A display apparatus is provided. The display apparatus comprises an electronic display assembly, a heat exchanger, a fan, and a cleaning device. The heat exchanger comprises one or more internal heat dissipation pathways and one or more external heat dissipation pathways. The one or more internal heat dissipation pathways are thermally coupled to the electronic display assembly and the one or more internal heat dissipation pathways are thermally coupled to the one or more external heat dissipation pathways. The fan generates ambient air flow passing through the one or more external heat dissipation pathways. The cleaning device is connected to the one or more external heat dissipation pathways, and used for injecting a cleaning fluid into the one or more external heat dissipation pathways.

An electric component box installed in an outdoor unit of an air conditioner includes: an electronic component accommodation unit that accommodates an electronic component; an intake port through which air is drawn in from outside the electric component box; a discharge port through which air is discharged from inside the electric component box; and a cooler disposed in an airflow path extending from the intake port to the electronic component accommodation unit and that cools air.

An electronic device is provided. The electronic device includes a protective cover, an electronic module, and a heat exchanger. The protective cover has an opening. The electronic module is disposed below the protective cover. The heat exchanger is disposed between the protective cover and the electronic module. A sub-space is defined between the heat exchanger and the protective cover. The heat exchanger has a first flow path and a second flow path. The first flow path and the sub-space communicate. The second flow path and the opening communicate. The first flow path is isolated from the second flow path.

An electrical control panel including an enclosure box being sealed other than at an inlet opening and an outlet opening, a primary electrical component inside the enclosure box and having a first heat exchanger that transfers heat from the primary electrical component, one or more secondary electrical components inside the enclosure box that generate less heat than the primary electrical component, a second heat exchanger attached to the enclosure box and having an internal air passageway that includes an inlet opening and an outlet opening in fluid communication with the respective outlet and inlet openings of the enclosure box and defining therewith a sealed compartment, and one or more diverter elements direct a majority of the heated air from the first heat exchanger to enter the internal air passageway of the second heat exchanger without flowing over at least one of the secondary electrical components.

A fan unit for improved airflow within a display assembly is provided. Fans are provided at a housing which includes a rear wall defining a curved shape with peaks to accommodate one of the fans and a valley between adjacent ones of the fans. The fan units induce relatively laminar flow within certain portions of an airflow pathways extending with the display assembly and relatively turbulent flows in other portions of the display assembly when activated.
