How do you prevent convectional heat in a cooler?

You cannot prevent it but you can minimize the convection by putting the ice cube to the lowest portion of the cooler.

convection is the transfer of heat by the flow of air. Duct tape prevents air from flowing outside of the ducks.

You have a couple of options.\n\n1. Install insulation in the ceiling and walls.  Be sure to prevent the insulating material from contaminating the chickens.  This won't really reduce the humidity, but it should keep the house from warming up as fast in the morning.\n\n2. Replace the pad coolers with air conditioners.  Would need insulated walls and ceiling to prevent this from becoming hugely expensive.\n\n3. Put the poultry house underground.  Make sure it is properly ventilated to prevent build up of radon.

Get a higher rating transistor and provide a generous heat sink. The general rule of thumb is that you can touch the heat sink and it should just feel warm and not burn you.

It's overheating.  You need to get a cooling pad.

1.  Do the easy things first.  Make sure that air gets to the air cooling system; clear leaves, dead raccoons, etc.\n\n2.  Since this is a chilled water system, make sure the water (or other fluid) is chemically correct.\n\n3.  Make sure the compressors are compressing properly, the pumps are pumping, and the fans are blowing.\n\n4.  If you get to #4, you're in major retrofit/replace territory.  You might get away with retrofitting with water cooling.  Otherwise, you'll have to gut the thing and start over with a bigger system.

A desert cooler takes advantage of very low relative humidity to acheive its cooling properties.   Rather than relying upon a refrigerant system (i.e. Freon) with a compressor to circulate the refrigerant, a desert cooler uses evaporation of water to remove heat.  With a low relative humidity, water can evaporate quite rapidly, taking a lot of heat energy along with it.  \n\nThere are a variety of different techniques to exchange and remove heat from the air.  One that is used in less arid climates is called a swamp cooler, in which water is pumped from a pond, through a heat exchanger and then back through a fountain in the pond.  The fountain aids in the evaporative process, helping to keep water cooler.  \n\nWhile a desert cooling system may not be able to develop as cold of temperatures as a refrigerant-based system, it still can effectively reduce the air temperature, and do so using less electricity since a compressor is not required to run.

How far below?\n\nWater has quite a high thermal conductivity value.  Depressing the freezing point can be obtained by adding a salt, such as table salt (sodium chloride) or even calcium chloride.  Maple Leaf Gardens (the old NHL hockey arena in Toronto, Ontario) use to use a brine (salt water) solution in the cooling system to keep the ice frozen.\n\nIf you weren't worried about corrosion, you could try a brine (saturated salt solution) in your cooling system.  Water has a thermal conductivity of approximately k=5 to 6 mW/cm/K (relative to carbon tetrachloride or toluene being close to 1 and still able to go well below 0C/32F and remain liquid).  (CRC Handbook of Physics and Chemistry...do your own unit conversions)\n\nDon't let the brine leak though....

get a cooling pad, it's a base you put your laptop on with fans in it that keeps it cool.  You can get them anywhere, and they're relatively decent priced.  I got one at the local computer store for $40

Get a couple of fans and make a "wind tunnel" effect, to move air thru your room, and not just push it around.  By pulling air from another room, you should be able to cool down yours.\n\nI found that putting a bowl (metal works best) of ice in front of a fan will cool things down until the ice melts.

i would not use water cooled. add more case fans, pci slot fans, and a bigger heat sink. water cooled are very prone to leaks.

Use a bigger heatsink. Or add more case fans, If the insides of your comp are a bores nest of wires try bundling and cleaning them up. That will improve airflow.

Either drop the temperature (remove the enthalpic - heat - energy) or increase the pressure (the less space it has to move freely the closer to solid it becomes) or both

Peltier Coolers\n\nFor those that are serious about processor cooling, there is a heavy-duty solution for keeping the processor at a comfortable operating temperature. These devices are called Peltier coolers, named after the Peltier effect, the scientific principle that explains how they function.\n\nIn a nutshell, the Peltier cooler works like a tiny "air conditioner" for your processor, except it is a solid state air conditioner that works without any liquids or compressors. A Peltier device pumps heat from one of its sides to the other, so one is cool and the other warm. The cool side is placed next to the processor, and the warm side has a heat sink attached to it. In this way heat is constantly pumped away from the surface of the CPU.\n\nThe Peltier cooler is the best form of processor cooling currently available. It keeps the processor at a low temperature, and since the Peltier cooler does not use moving parts, it is not subject to failure the way CPU fans are. Of course this performance comes at a cost, and these devices are more expensive than other cooling options. They can also be complicated to set up, and if done incorrectly, can cause problems or even equipment failure. For most people, the Peltier cooler is overkill and not worth the extra money (or hassle). These devices are popular amongst those who engage in overclocking, who run their systems over their rated speed specs and therefore have more heat problems than the average user.\n\n\n--------------------------------------------------------------------------------\n\nFan Failure / Over-Temperature Alarms\n\nAs mentioned in the section on active heat sinks, failure of the CPU fan can lead to rapid overheating of the system. To combat this problem, companies have invented devices intended to detect this situation and warn the user, who can take action to correct it before the heat becomes a problem.\n\nThese devices usually work in one of two ways. One type monitors the electrical level on the power line supplying the CPU fan, directly detecting if the fan fails. If it does, an audible alarm is sounded. The other type uses a thermometer to monitor the temperature of the processor. If the temperature exceeds a certain threshold value, an audible alarm is sounded. This is sometimes also called an over-temperature alarm, and is more robust than the other kind since it will warn you of any condition that might be causing the processor to overheat, not just fan failure.\n\nNote: These devices can cost more than a good quality active heat sink itself, so they are typically only used by those for whom system failure is a major concern. Also, putting this sort of protection on a cheap $5 CPU fan is probably kind of silly compared to just spending a few dollars more to get a good one.
