Definitions
- the present invention relates to a working fluid for a latent heat transport device and a method for operating a latent heat transport device using the same.

- the major feature of each is that the working fluid can be circulated without using external force such as a pump.
- Heat pipes are applied to relatively small cooling devices, such as cooling devices for heat generating parts of semiconductor elements and electronic devices, and two-phase sealed thermosyphons do not require wigs and are simple in structure. It is widely used for gas heat exchangers, promoting snow melting on roads and preventing freezing.

The evaporated gas diffuses in the pipe and releases the latent heat at the other end (low temperature part) to condense. The liquid returns to one end (hot part) of the pipe again by gravity or capillary force, and heat is transported from the hot part to the cold part.
- a heat pipe is mainly composed of three elements: (1) hydraulic fluid, (2) a wig or capillary structure, and (3) a container or container.
- the required requirements for hydraulic fluid are as follows: However, the first thing to consider is the operating steam temperature range.
- ⁇ is the surface tension of the hydraulic fluid (NZm)
- L is the latent heat of vaporization of the hydraulic fluid (kj / kg)
- ⁇ is the viscosity of the hydraulic fluid (Pa ⁇ s).
- the merit number varies with temperature.
