An outdoor display apparatus comprises a case including an inlet and an outlet, a display module disposed inside the case and including a display panel on which an image seen through at least a portion of the case is displayed, and a heat exchanger. The heat exchanger comprises a first portion located on a first flow path formed to circulate air to the display module, a second portion to receive heat from the first portion, and located on a second flow path on which outside air is heat-exchanged with air, and a phase change material provided to circulate between the first and second portions, and provided to change a phase from a fluid to a gas. The case comprises a partition wall provided to isolate the first flow path and the second flow path from each other, and the first portion and the second portion are disposed obliquely.

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. The solar energy harvesting device is located above the housing. The solar energy harvesting device has a first footprint, and the housing has a second footprint which is smaller than the first footprint.

An electronic device includes a casing, a heat generating element, a heat dissipation plate, and a centrifugal fan. The casing has a front side, a rear side, a peripheral side, and a plurality of vents. The peripheral side is located between the front side and the rear side, and the vents are distributed on the peripheral side. The heat generating element and the heat dissipation plate are disposed in the casing, and the heat generating element covers the heat generating element. Heat generated by the heating generating element is conducted to the heat dissipation plate. The centrifugal fan is disposed in the casing and is located on a same side of the heat generating element and the heat dissipation plate. The centrifugal fan is adapted for omnidirectional air discharge and an airflow generated from the centrifugal fan dissipates the heat out of the casing through the vents.

A solar powered display assembly and systems and methods for the same are provided. A solar energy harvesting device is electrically connected to a display unit which is connected to an electrical grid. At least one structural member extends between a housing for the display unit and the solar energy harvesting device such that a bottom surface of the solar energy harvesting device is elevated above, and spaced apart from, a top surface of the housing such that shade is periodically cast on the display unit. 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 dissipation device, a heat dissipating method, and a terminal are described. In an embodiment, the heat dissipation device, a heat dissipating method, and a terminal are configured to correspondingly form at least one ventilation wall that is configured to dissipate heat on different heat source positions of the terminal, and form a flow path of the heat dissipation airflow generated by the at least one ventilation wall, based on different heat source positions of the terminal in different applications. In an embodiment, the entire heat dissipation of the terminal can be achieved by the flexible and variable flow path to provide a good user experience.

A display assembly includes a housing which at least partially encloses an image assembly. A cover positioned forward of, and spaced apart from, the image assembly forms at least a portion of a forward surface of the housing and permits viewing of images displayed at the image assembly therethrough. A fan assembly moves air through an airflow pathway within the housing which includes a front channel between the cover and the image assembly and a rear chamber behind the image assembly. One or more solar energy reduction layers are associated with the cover and prevent at least some ambient sunlight striking the cover from traveling therebeyond.

An electronic apparatus has a heat-exchanger within a housing exchanges heat between internal and external fluids without direct contact between the fluids. The internal fluid circulates within the housing and the external fluid is received external from the housing and output external from the housing 120. The housing includes is a heater; impellers; a controller for controlling the heater and the flow of fluids through the heat-exchanger; and temperature and humidity sensors. The controller receives temperature and humidity data from the sensors; processes the data to indicate a current dew point within the housing; and compares the current dew point with a current location temperature at or adjacent the heat-exchanger. If the current location temperature is at or below the current dew point, the controller raises the temperature at at least one location on the heat-exchanger and/or activates the heat source to raise the temperature.

The present disclosure relates to a cooler and to a display device having the same, where a heat-exchanger of the cooler is arranged on a side surface of a display unit in order to simplify the structure and to make a slimmer display device. The cooler includes a closed air circulation pathway circulating between the front, rear and sides of the display unit; an open air flow pathway that flows in the length direction of the side of the display unit; and a cooling module that is installed on the side of the display along the length direction of the display, and that includes the heat-exchanger, where the closed air circulation path and the open air flow part are adjacent, thereby causing heat-exchange.

A heat-management device includes an array of recesses distributed across an external surface of a thermally conductive body. The device includes an array of protrusions interspersed with the array of recesses that form a network of cavities within an internal volume of the thermally conductive body. The array of recesses and the array of protrusions define a non-planar interface that is complementary to a curved surface of a heat source. A fluid volume can be retained within the network of cavities at a pressure lower than atmospheric pressure. The heat management device includes a cooling operation mode wherein the fluid volume absorbs heat from the heat source through the non-planar interface and dissipates heat away from the heat source through the network of cavities.
