| 摘要 |
<p>The present invention relates to a device for transfer of heat energy in a well logging tool, where a variable heat flow from a chamber for electronics via a thermovalve is transmitted into a heat sink consisting of cooled metal, thereby establishing an approximately constant temperature in the chamber for electronics. The device comprises an electronics modular unit and a heat sink modular unit, which modular units are connected via an intermediate section, where a heat-regulating thermovalve provides heat conduction between a conical piston and a conical piston seat, for transferring heat energy.</p> |
