I have some electronic equipment that requires cooling. The cabinet is 36 x 30 inche Hoffman enclosure, the cabinet is not located close enough to pipe air-conditioned air into it. I need to find a small cooling unit or heat-exchanger to maintain proper temp and humidity. If anyone has any suggestions to help me I would appreciate it.

These make use of the thermoelectric effect: current through the device cools one junction and heats the other. You can buy devices sized suitably for, say, a picnic cooler. NOTE: efficiency is terrible, but they're solid state, silent, and EXTREMELY reliable. The best way to use them would probably be to put the parts that need cooling on a heatsink and cool the heatsink. You also need a heat dissipator on the hot side to get rid of the heat you're pumping + the heat dissipated by the cooler itself. Sources are: MELCOR in New Jersey and MARLOW Industries Inc, Garland Texas. They're generally happy to supply application information. PS: They're fascinating devices, they're also reversible. heat one side, cool the other and you get current (again very inefficient) out the wires.
