When the mystery of boiling of fluids in the form of micro-channels was unveiled by scientists, formulas and models that can be used to cool high-power electronic gadgets was cracked. The high-power electronics in question include hybrid and electric cars, computers, aircraft, and several other devices. According to Suresh Garimella of Purdue University, Mechanical Engineering department, if a liquid is set in cooling system, it is possible to analyze the amount of fluid removed rather than heating the liquid to a temperature that is less than the boiling point.

Liquids that are boiled in tiny channels would behave differently from those boiled in large cooling systems. Spherical bubbles are not formed when liquid is boiled in the tiniest channels. Instead, a long continuous oblong slug or liquid annulus is created in liquid form. The influence of the liquid’s boiling behavior is determined by each channel’s cross sectional area. The innovative cooling system that makes use of the smallest channels can also be employed in electric and hybrid cars. The cooling system can help in preventing such devices from overheating. Some of the devices susceptible to overheating include high-power and bipolar transistors that are often fitted in green and clean electric and hybrid cars. Chips are required when accelerating a car from zero to 60 mph in ten or less seconds. These chips play a vital role in driving of electric motors, as well as switching large power amounts to electric coils from the battery pack. Electric motors function as generators when braking the car and this leads to production of power for recharging battery packs. It has been proven that high-power gadgets produce an amount of heat that is four times that produced by normal computer chips.

Researchers have discovered that a dielectric liquid can be used in electric and hybrid cars. This is a fluid that does not conduct electricity and can be directly used in circuits where they do not cause electric shots. Micro-channels were also directly engraved on silicon chips’ tops. Since both the chip and channels are made of silicon, expansion from heating does not cause a significant difference. With the cooling channels between each chip, it is extremely easy for the chips to be arranged on top of each other. The benefits of high-speed camera have also been utilized by researchers to capture the circulating fluid’s behavior. Researchers aimed at testing a broad range of channel sizes. Generally, the system is effective for cooling electric controls in hybrid and electric vehicles.
