Abstract
The device and methods described herein relate to the isothermal heat transport through an intermittent liquid supply to an evaporator device, thereby enabling high evaporative heat transfer coefficients. A liquid and vapor mixture flows through miniature and micro-channels in an evaporator and addresses flow instabilities encountered in these channels as bubbles rapidly expand. Additionally, a high percentage of the fins are exposed to vapor and limit the required charge of refrigerant t within the system due to effective condensate removal in the condenser.
Claims6
A condenser;
- an evaporator fluidly coupled to the condenser through a vapor tube and a liquid tube;
- the evaporator having a top, a bottom and sides, wherein the top is configured with an orifice in fluidic communication with the vapor tube, and the top is also configured with an orifice in fluidic communication with the liquid tube;
- wherein liquid enters the evaporator from the liquid tube and vapor exits the evaporator to the vapor tube;
- a plurality of evaporator fins positioned within the evaporator creating channels therebetween, wherein at least a portion of the plurality of evaporator fins having cut-outs allowing vapor to flow between the channels, wherein each of the plurality of evaporator fins also having cut-outs allowing liquid to flow between the channels;
- and
- a vapor blocking fin configured without cut-outs allowing vapor to flow between channels to limit the vapor backflow from the evaporator into the liquid tube.
