literally a coolant pump?
just get a water cooling kit with all the parts you need.
But keep in mind this things only lower the temperature down to room temperature, just they are more efficient than just a fan.
Same as the one in your picture.
In order to really cool the air you need a compressor, an evaporator and a condenser in your circuit, same as in a fridge or any AC unit.
Of course this is expensive to make and it needs proper tools, materials and processes only a professional is capable to operate.
So you do better and cheaper by getting that portable AC unit soon or later in the end.
