Intermittent Thermosyphon

摘要

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 within the system due to effective condensate removal in the condenser.

主权项

1. A thermosyphon, comprising:
a condenser having a first condenser orifice configured to allow vapor to enter the condenser; the condenser further having a second condenser orifice configured to allow liquid to leave the condenser; an evaporator having a first evaporator orifice configured to allow vapor to exit the evaporator; the evaporator further having a second evaporator orifice located below the second condenser orifice and configured to allow liquid to enter the evaporator; a plurality of evaporator fins positioned within the evaporator, wherein the evaporator fins direct movement of fluid within the evaporator from the second evaporator orifice towards the first evaporator orifice; a vapor tube fluidly coupling the first evaporator orifice to the first condenser orifice; and a liquid tube fluidly coupling the second condenser orifice to the second evaporator orifice.
