Abstract
In some embodiments, an apparatus includes a tool for a downhole operation. The tool includes a downhole power source to generate power. The tool also includes a cooler module to lower temperature based on the power.
Claims14
1-11. (canceled)
A downhole tool for taking measurements in a well, comprising,
- a tool body;
- a first electrical component within the tool body, the first electrical component only operable below a first temperature that is lower than will be encountered throughout the entire duration of taking measurements in the well;
- a second electrical component within the tool body, the second electrical component preferably operable above a second temperature that is higher than temperatures that will be encountered throughout the entire duration of taking measurements in the well;
- a heat sink associated with the first electrical component to protect the first electrical component from temperatures above the first temperature, the heat sink comprising a phase change material;
- and
- a heater associated with the second electrical component to selectively provide heat to the second electrical component to raise the temperature at least to the second temperature.
3 more elements
A downhole tool, comprising:
- a body member to traverse a well;
- a power source operable only at temperatures below those in at least a portion of the well;
- a first heat sink surrounding at least a portion of the power source, the heat sink comprising at least one phase change material;
- an electrical component operable only at an operating range of temperatures above those in at least a portion of the well;
- and
- a heater operably associated with the electrical component to raise the temperature to the operating range.
3 more elements
A method of operating a downhole tool, comprising the acts of:
- activating a heater in the downhole tool to raise the temperature of a first electrical component in the tool to an operating range;
- and
- using a first heat sink comprising a phase change material to protect a second electrical component.
