Embodiment Construction

[0027] figure 1 An example of a temperature control device according to an embodiment of the present invention is shown. The device 2 includes a thermal chamber 6 for housing a hard disk drive 12 . The thermal chamber 6 can be used as both a heat sink and a heat source. In use, the temperature control device is usually set within the frame matrix, which will be referred to below image 3 describe. The thermal chamber 6 is typically a suitably shaped metal block with the required cooling fins and air ducts to facilitate efficient heat transfer through the gas between the hard disk drive under test and the thermal chamber.

[0028] In the particular embodiment shown, the heat pump 8 is arranged in heat exchange with the thermal chamber 6 . The heat exchanger 10 is also provided so as to be able to exchange heat with the heat pump 8 . By varying the operation of the heat pump 8, the temperature of the thermal chamber 6, and thus the temperature of the environment in which th...

Abstract

The invention provides a temperature control apparatus for a hard disk drive, the apparatus comprising: a thermal chamber for receiving a hard disk drive; and an oscillatory air movement generator forgenerating air movement within a region between the thermal chamber and a said hard disk drive when received in the thermal chamber, thereby to facilitate heat transfer between the thermal chamber anda said hard disk drive.

Description

technical field [0001] The invention relates to a hard disk drive temperature control device and a method for changing the temperature of the hard disk drive. Background technique [0002] During the hard drive manufacturing process, hard drives need to be tested to ensure they meet the required specifications. As part of the test, the temperature of the hard drive needs to be controlled. During the test, the temperature of the hard drive was varied over a wide range. [0003] During normal operation of the hard disk drive, ie, when the hard disk drive is normally used by an end user, it is also required that the temperature of the hard disk drive be maintained within a predetermined range. [0004] It is known to test hard disk drives in an apparatus comprising a test rack comprising a matrix of frames for housing housings containing the hard disk drives to be tested. In order to provide control over the temperature at which the hard disk drive is subjected to testing, a...
