Disclosed is a heat radiation device, which is in contact with a first heat-producing component having a higher value of guaranteed temperature and a second heat-producing component having a lower value of guaranteed temperature, and the heat radiation device comprises a metal member provided with a slit. The metal member is divided by the slit to have two heat radiation regions, a first heat radiation region and a second heat radiation region that are loosely coupled with each other in terms of heat conduction. The first heat-producing component is placed in contact with the first heat radiation region, and the second heat-producing component is placed in contact with the second heat radiation region.

Heat radiation device and electronic equipment using the same

A plasma display device includes a plasma display, a chassis having conductivity that supports the plasma display, a tuner circuit, a scan driver, a sustaining driver and so forth used to display a video on the plasma display, a back cover that covers the chassis, the scan driver, the sustaining driver, etc., and a shield body that covers the tuner circuit. The shield body is electrically connected to the chassis and to the back cover.

Plasma display device capable of reducing unwanted radiant noises

A plasma display device includes a plasma display panel, a chassis disposed on the plasma display panel with a heat-conducting sheet in between, a small-signal processing circuit board disposed on a rear face of the chassis, a thermal sensor, a thermal sensor fixture for installing the thermal sensor, a front frame, and a back cover having a ventilation area with multiple ventilating holes. The thermal sensor fixture has a shielding wall around the thermal sensor and is disposed on a rear face of the small-signal processing circuit board. The thermal sensor is disposed at an intermediate position between the plasma display panel and the back cover at a position facing the back cover.
