Temperature hysteresis heat pipe
WebThe loop heat pipe (LHP) was invented in Russia in the early 1980's. It is a two-phase heat transfer device that utilizes the evaporation and condensation of a working fluid to transfer heat, and the capillary forces developed in fine porous wicks to circulate the fluid. ... Peculiar behaviors in LHP operation such as temperature hysteresis and ... Web16 Jun 2004 · Hysteresis in five different Thermochromic Liquid Crystals (TLCs), both narrow-band and broad-band, has been investigated. All were found to exhibit a similar hysteresis behavior during cooling relative to heating. This hysteresis is characterized by a decrease in reflectivity and a shift in the temperature associated with the peak reflected …
