In one embodiment, a heat dissipating apparatus includes a chassis positionable within a housing of a downhole tool. The heat dissipating apparatus also includes a heat sink coupled to the chassis and a displacement mechanism coupled to the heat sink. The displacement mechanism is actuatable to move the heat sink, with respect to the chassis, between a first position and a second position such that in the first position the heat sink is radially retracted toward the chassis to form a gap between the heat sink and the housing and such that in the second position the heat sink is radially extended from the chassis to contact the housing.

Dissipating heat from a downhole heat generating device

The present disclosure relates to heat dissipation apparatus that may be used within a downhole tool. The heat dissipation apparatus may include one or more of a cover configured to attach to a heat generating device, a thermal conduit thermally coupled to the cover, and a heat sink thermally coupled to the thermal conduit, in which the heat sink is configured to dissipate heat from the heat generating device through the cover and the thermal conduit.

Axially loaded tapered heat sink mechanism

A downhole tool configured for conveyance within a wellbore extending into a subterranean formation, the tool comprising an electronics system and a heat-dissipating apparatus. The electronics system includes a controller, a memory, and surface communicating means, at least one of which is a heat-generating source. The heat-dissipating apparatus includes: a chassis engaging the heat-generating source and having a fluid passageway allowing fluid flow therethrough; a radiator for further heat dissipation; a pump; sensors to measure temperature of the chassis and the wellbore; and a compensator to regulate the pressure of fluid in the passageway.
