TRENDS IN COOLING YOUR ELECTRONIC GADGETS

In today's technical world electronic devices have a great role in our daily lives, for that it     needs  a suitable performance, but due to it's huge amount of unwanted heat dissipation most of the   electronic components may fail. So for the prevention from this failure you must be having some     cooling techniques. You can use heat pipe method, designing some heat sinks and blowers for the   better performance. Although water is the best cooling component which is a conventional source.      Following are the some types of cooling system used in electronics gadgets recently.

         

  • Air cooling
  • Vacuum cooling fans
  • Liquid cooling 
  • Heat Pipes   
     
                         



Cooling systems plays important role in the manufacture of electronic devices .

   
   Cooling system is classified as follows:

              1)   Liquid cooling:

                   Liquid cooling is a little more complicated. Referring back to high school chemistry,  there is a term called thermodynamics. Thermodynamics states that heat moves from warmer  objects to colder objects. This is the same principle that goes into liquid cooling. In a liquid cooled system a thermally conductive material, such as copper, transfers heat from a warm    component to the liquid in the tube. The liquid then moves to the actual cooling device which absorbs the heat from the liquid. The liquid loops back around and continuously repeats this process keeping the desktop at a cool temperature to perform at its’ peak level.
                 It transfer heat up to four times better than an equal mass of air. This allows higher performance cooling to be provided with a smaller system. A liquid cooled cold plate can replace space-consuming heat sinks and fans and, while a liquid cold plate requires a pump, heat exchanger, tubing and plates, there are more placement choices for cold plates because they can be outside the airflow .

       The most commonly used coolants for liquid cooling applications today are:
                    *Water
                    *Deionized Water
                    *Inhibited Glycol and Water Solutions
                    *Dielectric Fluids.


       2)Air cooling:

                 Air cooling is a standard method of system cooling used to method of dissipate heat. The object being cooled will have a flow of air moving over its surface. Most air cooling systems use a combination of fans and heat sinks, which exchanges heat with air. It works by expanding the surface area or increasing the flow of air over the object to be cooled, or both. 
                The addition of fins to a heat sink increases its total surface area, resulting in greater cooling effectiveness. he key to understanding air cooling is very simple – fans. A good air cooling system involves a plethora of fans including case fans, graphics card fans, and CPU fans with a strong heat sink on the bottom. All of these fans work cohesively to keep the vital components in the system at an optimal temperature level .

      3)Vacuum cooling fans :


       Vacuum cooling fans work on a unique principal. By attaching to the air outlet, they are able to      suck air through at a higher velocity than your stock cooling system.
        Some of these systems have boosted cooling performance by a significant margin.  Opolar has produced several iterations of their laptop vacuum cooler.
        Vacuum cooling has notable advantages including fast cooling rate, cleanness, and high energy   efficiency.

        3)Heat pipes

                  Heat pipes are not in general a low cost solution to the cooling problem, but they are         most effective and have great potential as power levels and volume requirements increase. For 
these reasons heat pipes have been applied up to now mainly in applications with special working conditions and requirements, such as in space thermal control, in aircraft devices, in traction drives in audio amplifiers, in cooling of closed cabinets in harsh environmental conditions, etc.           
                Heat pipes, because of their high thermal conductivity, provide an essential isothermal environment with very small temperature gradients between the individual components. THE high heat transfer characteristics, the ability to maintain constant evaporator temperatures under different heat flux levels, and the diversity and variability of evaporator and condenser sizes make the heat pipe an effective device for the thermal control of electronic components.

              Benefits  of  using cooling system :

                 A cooling system must be provided not only to prevent damage to the vital parts of the         electronic gadgets, but the temperature of these gadgets are maintained to within certain limits  in   order to obtain maximum performance of the electronic gadgets .

   Advantages of liquid cooling over air cooling:


            



      Liquid cooling  is  is more efficient in removing excess heat. This advantage comes from the fact that water or any liquid coolant has higher heat capacity, density, and thermal conductivity than air. This allows the system to transfer more heat over greater distances .
    Liquid cooling offers higher thermal conductivity than air cooling. Water has unusually high specific heat capacity among commonly available liquids at room temperature and atmospheric pressure allowing efficient heat transfer over distance with low rates of mass transfer.

      2 . One plus :
          To prevent the One Plus 7 Pro from overheating, Company is once again installing a special cooling system. A ten-layer liquid cooling system is intended to ensure a cool  smartphone, especially when playing games.
