There are large-scale devices where gas starts vibrating when you add heat. The best known from physics lab experiments is the Rijke tube and the oldest is probably the “Kibitsu no kama” (a rice cooker of specific proportions which was used by monks in Japan for fortune-telling). These produce considerable quantities of audible sound, and they are fun toys…
…but in this case, the spontaneous oscillation of coolant at a microscale seems to speed up heat transfer magnificently. Not just fun, but very practical. A great number of tiny heat engines, with no moving parts but the working fluid, with the goal of transfering heat away from its source.
Really cool thanks for the insight! My concern was with more moving parts like pumps etc. it also is more prone to failure. But this sounds like all the benefits without the downsides.
A sort of self-excited active cooling, yes.
