Attaining PhD in thermodynamics is my next major aim. I am interested to research on
the future cooling technique.I thought 2-phase evaporative cooling system techniques might
become a future cooling system that will be used by cars and industries. The proposed research
intended to develop the model to assess the pool boiling and flow boiling heat transfer rates
through the excessive speed optical diagnostic system. This cooling option is considerably more
energy efficient than cooling with refrigerant (standard air conditioning), but it's unsuitable for
all cooling applications. In terms of phases the evaporative cooling occurs in two steps, initial
phase cooling and secondary phase cooling. In the first phase hot air is passed through a heat
exchanger which is cooled by evaporation on the outside of heat exchanger. The air current from
outside of the heat exchanger helps in cooling by convection. In the initial phase the air doesn't
collect any excess moisture. In the second step the air from the heat exchanger is passed through
a water-soaked pad that helps in extra cooling of the air and the air picks up extra humidity. A 2-
phase evaporative cooling system provides cool indoor air that has humidity range of 50%-60%,
while the typical direct evaporative system delivers cool indoor air with humidity range around
70 % .The reason is that 2 phase evaporative cooling system consist of both evaporation and
condensation though heat exchanger, while for the single phase the cold plate helps to ensure the
cooling process.
The majority of people know about siphoned single stage cooling. It's utilized in vehicle
radiators and as cold plates to cool electronic components and automotive systems. In such
frameworks, a liquid, for example, water, ethylene glycol, or a refrigerant is transmitted from a
siphon through a cold plate where it expels the waste warmth from the device. Now the working
fluid at an elevated temperature is carried out to a heat exchanger, where the waste heat is
vanished. After this the working fluid is deployed to a reservoir tank from where it prepares and
proceeds to the next cycle. These systems work effectively in many applications, but for a place
that has significantly high amount of enthalpy then it becomes necessary to have a high amount
of liquid flow rate, which requires larger pumps and consume more power. As the liquid passes
through the cold plate passage, it gains heat. The gain in enthalpy delta T from inlet to outlet is
significant. Two phase evaporative cooling system use the same fundamental components of a
