Liquid coolers excel at delivering cooling to concentrated heat sources such as laser diodes and for delivering cooled fluid into remote or compact locations where the cooling assembly itself cannot be located. The basic operation is simple: fluid flows in one tube, it is cooled, and then it flows out the other tube. An external pump is required, and typically small DC magnetic-drive pumps are used to minimize the amount of pump power (heat) that is imparted to the fluid.

Capacity Rating: 54 watts at a 0°C temperature difference.
Example Applications: Recirculating water chillers, cooling in-process fluid, and gas drying in analytical instruments.
Features: A four-pass liquid loop provides a very good thermal link between the fluid and the two thermoelectric modules. The aluminum portions of the liquid path are hard-coat anodized to prevent corrosion. For stainless steel liquid paths select a cold-plate style cooler and add an optional LC-SSX1 stainless steel liquid plate. Can be used for heating and cooling. This cooler is powered by 24 VDC and is compatible with all of our temperature controllers.
Capacity Rating: 184 watts at a 0°C temperature difference.
Example Applications: Laboratory instruments, laser diode cooling, medical products, recirculating chillers, temperature baths.
Features: High-density bonded-fin heat sink, an eight-pass liquid loop, and six thermoelectric modules for high capacity in a compact size. As with all of our liquid coolers it can be customized with swirl inserts in the liquid loop to improve efficiency at low flow rates. Can be used for heating and cooling. This cooler is powered by 24 VDC and is compatible with the TC-720 series, TC-36-25 series, and TC-48-20 series temperature controllers.
Typically attached to our standard cold plate coolers to make a liquid cooler with a 316 stainless steel (SS) liquid path. The LC-SSX1 is a heat sink / passive exchanger only; and the capacity of system will vary depending on the cold plate cooler to which it is attached. Used alone it has a 0.033 K/W thermal resistance at a 25 °C, 1.6 L/minute water flow rate. Useful for laboratory instruments, laser diode cooling, medical products, recirculating chillers, or temperature baths utilizing high purity or corrosive liquids.
