Abstract

A droplet emitter with an array of droplet emitting devices constructed such that one flowing liquid is used to create the droplets while a second low acoustic impedance liquid can be used to both make the transfer of acoustic energy to the first liquid more efficient and help maintain a uniform temperature of the droplet emitter array. Both the emission fluid and the low acoustic impedance fluid can be circulated through the droplet emitter to allow for excess heat generated by control electronics to be transferred to the flowing. This prevents for instance excess heat build-up within the droplet emitter and allows for higher more accurate droplet emission.
