Abstract
A hard disk system having a disk housing shock mounted in an environmental housing employs a device to transfer heat from the disk housing while avoiding any mechanical connection that would impose significant rigidity between the disk housing and the environment housing so as to defeat the shock mounting. In one embodiment, a Peltier effect heat pump has a cold side in contact with the disk housing and a hot side in contact with heat-conducting spring fingers contacting the environmental housing. In another embodiment, a fan is positioned in a space between the outside of the disk housing and the inside of the environmental housing to circulate air around the disk housing, while a Peltier effect heat pump moves heat to the environmental housing. In yet another embodiment, the fan is positioned in the space between the disk housing and the environmental housing, and the Peltier effect heat pump has a cold side in contact with an exterior surface of the environmental housing and a hot side in contact with a heat sink. In still another embodiment, a flexible heat pipe comprising a shell containing a low vapor-point liquid is positioned in the space between the outside of the disk hou…
