- the primary channel 405 is a rectilinear channel of circular section
- the secondary channel 407 is a rectilinear channel with a ring section, the smaller diameter of which is greater than the diameter of the primary channel, the primary 405 and secondary 407 channels having the same longitudinal axis.
- the embodiments described are not however limited to this case ⁇ ticular party.
- the primary 405 and secondary 407 channels pass right through a layer 409 of a thermally insulating material, which separates the cavity 401 from the cavity 403.

- the ring 219 itself rests on a peripheral portion of the upper face of the electrode 417, above the side walls 415 of the cavity 401.
- a cavity 425 thus separates the electret layer 419 from the electrode 421.
- the electrodes 417 and 421 and the electret layer 419 form a capacitive electret transducer.
- the electrodes 417 and 421 are respectively connected to nodes or output terminals OUT1 and OUT2 of the conversion device 400.
- the wall 411 is intended to be brought into contact with a cold source
- the electrode 421 is intended to be brought into contact with a hot source.
- the cavities 401 and 403 and the channels 405 and 407 constitute a closed volume delimited by the walls 411, 413 and 415 and by the flexible electrode 417 which thus define an enclosure 430.
- a liquid 427 is introduced.
- liquid 427 is chosen so that its boiling temperature is lower than the temperature of the cavity 401 (hot cavity) in operation, and greater than the temperature of the cavity 403 (cold cavity) in operation.
- the primary channel 405 has an inner surface such that it ensures the displacement of drops of the liquid from the cavity 403 to the cavity 401, regardless of the orientation of the dispo ⁇ operative part 400.

- the operation of the device 400 is as follows.
- the vapor is transmitted by the channels 405 and 407 and condenses on the side of the cold cavity 403. A drop is then formed in the cold cavity 403. This drop is transported to the hot cavity 401 through channel 405, and the cycle starts again.
- the primary channel 405 has an opening large enough to pass drops of the liquid 427, and the secondary channel 407 has an opening too small to pass drops but large enough to transmit vaporized liquid or pressure.
- the diameter of the primary channel 405 is preferably of the order of the capillary length, for example between 3 and 5 mm, advantageously of the order of 4 mm, and the diameter of the secondary channel is preferably of the order of the capillary length divided by 10, for example less than 0.5 mm.
- the secondary channel 407 notably has the role of balancing the pressure between the cavities during the transfer of the drop from the cavity 403 to the cavity 401, in order to prevent a depression from being created in the cavity 403 which could block the transfer of gout.
- An advantage of the embodiment of Figure 4 is that the operation of the device is independent of gravity. The device can therefore be arranged in any orientation.
- the capacitive electret transducer is placed on the side of the cold source.
- the transducer may be placed on the side of the hot source, or two transducers may be provided, one on the side of the hot source and one on the side of the cold source.
- the TRANSDUC ⁇ tor capacitive electret is disposed on the side of the hot source.
- the transducer may be placed on the side of the cold source, or two transducers may be provided, one on the side of the hot source and one on the side of the cold source.
- the electret layer of the capacitive electret transducer is formed on one side of the rigid electrode of the transducer.
- the electret layer may be placed on one side of the flexible electrode of the transducer. In this case, however, care must be taken that the stacking of electricity flexible trowel and electret layer remains flexible enough to achieve the desired operation.
