Bubble generator
First Claim
1. A heat transfer assembly for transferring heat from a heat generating device to a circulating fluid, said heat transfer assembly comprisingan evaporator device having at least one microchannel formed therein, in thermally conductive contact with said heat generating device,a condenser device,actuating means and manifold means for circulating said fluid between said evaporator device and said condenser device,wherein said heat transfer assembly further comprises a bubble generator for generating bubbles within a tubular or channel liquid flow, comprisingmeans for generating one bubble at a pre-determined location within said tubular or channel liquid flow,means for repeating periodically said bubble generating step at said location, andmeans for controlling the frequency of said periodical bubble generating step,wherein said tubular or channel liquid flow is carried out within said microchannel, and wherein said bubbles consist of vapor of said liquid.
