Mini Desktop AirConditioner

Step 2 Cuttin Holes

Hehe.. cut holes.. for the fan... fitting nicely fot the fan to be fitted in..

then cut another hole at the other side so that the air will come thru it..

mount the fan at the opening of hole with folded monting tape..
i use mounting tape and and not glue because glue will eat up the styrofoam and will eat up ...causing holes!OMG serious.!

place the wires to the outside of your box so that power will be supplied in for the fan

 hey dude i am not as good as you are at this so 1 question ! 
why do we need a heat sink ?? & how effective is it ?

[Schober]

Getting into the science of it, the heatsink is made of a material (typically aluminum) with a low specific heat (it heats and cools quickly). The water that the heatsink is in has a relatively high specific heat (takes quite a lot longer to heat and cool). By design the heatsink has a number of thin fins on it to increase surface area and increase the dispersal of heat. By placing the fins of the heatsink in the water the energy is rapidly removed from it.. As the air is pulled past the heatsink it gives some of its energy to the heatsink, that energy quickly flows to an area of lower energy (the ice water) through the fins.

This system may be made more efficient by placing the larger part of the heatsink in the water instead of the fins. This would increase the surface area that is coming in contact with the air and more quickly remove the energy from it. Because of how thick the base of the heatsink is, it is going to take longer for it to cool than the fins and will store some heat inside it. Because it takes longer to heat the water than the heatsink it is okay to store some of that heat so that it may be dispersed at a rate that the water is able to agree with. It's better to store heat in the base than to try to force it to absorb the heat from the air.

This should make the air coming out of the unit cooler but it will also mean that you will need to replace the water more frequently because the speed at which the energy flows will be increased.
