摘要:
A thin display apparatus equipped with a video display panel controls rise in temperature of a disk drive by heat-transfer from high temperature internals of the apparatus by a simple configuration. A thermal insulating recess 12 is formed in a face of a rear side casing 10 which faces a disk drive unit 21, and a surface of the disk drive unit 21 mounted on the rear side casing 10 seals the thermal insulating recess 12. An area of the thermal insulating recess 12 sealed by the disk drive unit 21 becomes a thermal insulating layer between the rear side casing 10 and the disk drive unit 21, and the thermal insulating layer interrupts thermal transfer from the high temperature internals of the apparatus to the disk drive unit 21.

An environmental control system, or data pack, is provided in accordance with embodiments of the present invention. The system allows for audio and video recording on hard drive media in situations where temperature, vibration and humidity would otherwise have prevented the use of such technology. The system can be used in conjunction with an event recorder for use in motor vehicles, trains and the like. The environmental control system includes a thermoelectric module connected to the hard drive and to a housing. The thermoelectric module is for transferring heat between the hard drive and the housing in response to an applied voltage in order to maintain a hard drive temperature within a hard drive operable temperature range. The vehicle operating temperature range includes temperatures outside the hard drive operable temperature range.

A partition wall 10 composed of a conductor for partitioning the inside of an exterior packaging case 7 into two portions is provided and at the same time, approximately the whole face of at least one face of the partition wall 10 is covered by an insulation plate 11, and a table rotation device 82 and an optical pickup device 86 are disposed in a first chamber 72 in the exterior packaging case 7 partitioned by the partition wall 10 and insulation plate 11 and at the same time, a printed circuit board 4 is disposed in a second chamber 73. In this manner, a possibility of a phenomenon that the table rotation device or the optical pickup device is affected thermally based on the heat generated caused by the operation of electronic parts or the like mounted on the printed circuit board such that a malfunction or the like occurs will be avoided.

The invention relates to a device for reducing the noise level of a component (1) with moving parts, such as for example a hard disk in a PC and for cooling the same. The device consists of a housing (2), in which the component (1) is located and which is provided with ventilation openings (4) on opposing sides, through which a current of air for cooling the component can flow. According to the invention, the component (1) located in the housing (2) is completely surrounded by soundproofing material (3) and channels (5) for the supply and evacuation of the cooling air are configured in said soundproofing material (3).
摘要:
A computer including an acoustically shielded hard disk drive. Exhaust vents are provided in the computer housing above a convectively cooled power supply. The power supply and, if necessary, a plurality of fans mounted inboard from the intake vents, move the air throughout the computer. The resulting computer produces no more than 25 decibels of noise when in operation. A sound absorption layer surrounds the disk drive assembly. A heat sink mounted exterior to the sound absorption layer is connected by a heat conductive path to the disk drive assembly so as to conduct heat from the disk drive out to the exteriorly mounted heat sink. The disk drive may be immediately surrounded by a fluid containing pouch and a metal bracket.
