A heat generation element is disposed on the main board, and an orthographic projection of the heat generation element on the housing is located in an orthographic projection of the first support on the housing. The heat dissipation layer is disposed in contact with the heat generation element, and an area of an orthographic projection of the heat dissipation layer on the housing is larger than an area of the orthographic projection of the first support on the housing.

An electronic device may include a housing including a first housing and a second housing to move relative to the first housing, a flexible display supported by at least one of the first housing or the second housing and changeable in form of a display area based on a movement of the second housing relative to the first housing, a board module disposed inside the housing, and a seating portion that forms a seating space receiving the board module and supports the board module.

A thermal bridge includes an upper bridge assembly including upper plates arranged in an upper plate stack and a lower bridge assembly including lower plates arranged in a lower plate stack. Outer ends of the lower plates face and thermally couple to an electrical component. The upper plates and the lower plates are arranged in plate pairs. A spring element forces the upper plates and the lower plates of the plate pairs apart. The upper plates include upper limit tabs and the lower plates include lower limit tabs. The upper limit tabs and the lower limit tabs operate to limit spreading apart of the upper plates and the lower plates against the opening forces of the spring element.

This application is directed to a passively-cooled electronic device including a housing, a plurality of electronic assemblies and a plurality of thermally conductive parts. The electronic assemblies are enclosed in the housing and include a first electronic assembly and a second electronic assembly. The first and second electronic assemblies are disposed proximately to each other within the housing, and the second electronic assembly is substantially sensitive to heat, including heat generated by operation of the first electronic assembly. The thermally conductive parts are coupled between the first electronic assembly and the housing, and configured to create a first plurality of heat conduction paths to conduct the heat generated by the first electronic assembly away from the second electronic assembly without using a fan. At least a subset of the thermally conductive parts mechanically supports one or both of the first and second electronic assemblies.

An apparatus cools electronic circuitry. An enclosure surrounds the electronic circuitry and has plural surfaces. Air intake holes are disposed in at least one surface and face at least one first direction. Air exhaust holes are disposed in at least another surface and face at least one second direction different than the first direction. A heat sink is in thermal contact with the circuitry and conducts heat generated by the circuitry. When a fan operates, air is drawn from an exterior of the enclosure through the air intake holes, absorbs heat from the heat sink, and then is directed through the air exhaust holes into the exterior of the enclosure. The heat sink is further in thermal contact with the enclosure so that when the fan does not operate, heat is drawn from the circuitry to the enclosure via the heat sink and is dissipated from the exterior.
