摘要： A shape-morphing fin includes a fixed portion, a multistable portion, a coupling portion, and a vibration source. The multistable portion functions as a negative stiffness element. The multistable portion is selectively movable between a first position and a second position. The movement between first position and the second position is configured to remove the ice formation from the structure. The coupling portion couples the fixed portion to the multistable portion. The vibration source is configured to produce a resonant vibration to engage the movement of the multistable portion from the first position to the second position.

摘要： A novel method of deicing utilizing a fins-on-tubes type evaporator/heat exchanger system that is optimized for energy-saving inductive heating thereof, by configuring it to increase its resistance to a value at which the system's reactance at its working frequency is comparable to its electrical resistance. The system includes a set of tubes configured for flow of cooling material therethrough, and also includes a set of fins positioned and disposed perpendicular to, and along, the tubes, in such a way that at least a portion of the fins comprises longitudinal excisions therein.

摘要： A heat exchanger for separating a vapor component from a carrier gas is disclosed. The carrier gas is cooled in an outer chamber, causing a vapor component of the carrier gas to desublimate or condense onto an outer surface of an inner chamber, forming a solid product. A coolant is passed through the inner chamber to cool the carrier gas of the outer chamber. A means for causing the inner chamber to flex is provided, causing the solid product to fall from the outer surface of the inner chamber for collection. In this manner, the vapor component is separated from the carrier gas.

摘要： A heat exchanger includes a plurality of principal heat exchange sections and auxiliary heat exchange sections. Each of the auxiliary heat exchange sections is in series connection to a corresponding one of the principal heat exchange sections. The number of the flat tubes constituting each of the heat exchange sections is compared to the number of the flat tubes constituting a corresponding one of the auxiliary heat exchange sections, creating a tube number ratio, wherein the first principal heat exchange section, which is lowermost, has the smallest tube number ratio. Consequently, discharge of liquid refrigerant from a lower portion of the first principal heat exchange section is accelerated during defrosting, thereby shortening the time required for defrosting.
