Abstract (en)

Present embodiments relate to systems and methods for providing cooling to temperature sensitive components 52 of a downhole tool with an intermittent power supply. To provide one example, a downhole tool may include a temperature sensitive component 52, an enclosure 54, a cooling unit 56, and a heat exchanger 58. The heat exchanger 58 may also disable heat transfer between the temperature sensitive component 52 and the cooling unit 56 when the cooling unit is not providing the active cooling.
