SWITCHABLY ACTIVATED HEAT TRANSFER WITH MAGNETIC FLUID |
| 摘要 |
An apparatus includes a heat pipe with a fluid path. A first part of the fluid path is thermally coupled to a first region of a higher temperature and a second part of the fluid path thermally is coupled to a second region of a lower temperature. A difference between the higher temperature and the lower temperature induces a flow of a magnetic fluid in the fluid path. A switchable magnetic device is magnetically coupled to the fluid path. Activation of the switchable magnetic device reduces the flow of the magnetic fluid in the fluid path, which reduces heat transfer from the first region to the second region. |

1. An apparatus comprising:
a heat transfer mechanism comprising a fluid path, a first part of the fluid path thermally coupled to a first region of a higher temperature and a second part of the fluid path thermally coupled to a second region of a lower temperature, a difference between the higher temperature and the lower temperature inducing a flow of a magnetic fluid in the fluid path; and a switchable magnetic device magnetically coupled to the fluid path, activation of the switchable magnetic device reducing the flow of the magnetic fluid in the fluid path, which reduces heat transfer from the first region to the second region. |
