Cold Plates
Cold plates are usually the best choice of cooling method when the object to be cooled can be attached directly to the cold plate. The direct contact between the object and the cold plate allows the heat to be efficiently conducted to the thermoelectric (Peltier) modules. This, in turn, keeps the system operating as efficiently as possible and improves the stability and accuracy of temperature control.The cooling surfaces of these cold plates have been machined flat for optimum thermal transfer, and they have threaded holes for easy attachment of the object to be cooled. The user can also add extra threaded holes into the cold plate if needed (consult with TE Technology before drilling to determine locations in the plate to avoid). A threaded hole is also included in the side of the cooling surface for easy attachment of a temperature sensor.
If the object being cooled does not have a flat surface that is directly attachable to the cold plate, the user can make an adapter plate to bridge the surfaces. So, for example, you can cool a cylindrical object by making an adapter plate that is flat on one side and semi-cylindrical on the other. This aluminum adapter plate is attached to the cold plate using the threaded holes, leaving the cylindrical surface facing outward for interfacing to the cylindrical object. This principal can be applied to many other shapes and adapter types. If a larger cooling surface is needed a flat adapter plate can be added.

Model CP-031  Capacity Rating: 31 watts at a 0 °C temperature difference Example Applications: Small laser diodes and laboratory instruments. Features: This cold plate provides effective direct contact cooling in our lowest cost standard assembly. The lack of an extender block between the module and cold plate helps make this our smallest cold plate. The cooler is best suited for small heat loads where a large temperature difference is not needed. Powered by 12VDC, it has the lowest power consumption of any of our standard cold plates, which makes it compatible with all of our temperature controllers. |  |
| Model CP-036 Capacity Rating: 36 watts at a 0 °C temperature difference Example Applications: Medical and laboratory instruments. Features: Provides good cooling for small heat loads at low temperatures. This is made possible by using a large heat sink for only one thermoelectric module and an extender block that allows extra insulation between the heat sink and cold plate. Powered by 12VDC, its low power consumption makes it compatible with all of our temperature controllers. |  |
| Model CP-065 Capacity Rating: 65 watts at a 0 °C temperature difference Example Applications: Medical and laboratory instruments, thermal stabilization of electronic components, and laser diodes. Features: Two-module cold plate increases the heat-pumping capacity for cooling medium sized heat loads. Like all of our coolers, it can be easily customized to meet your production requirements: special cold plates, smaller heat sinks, different operating voltages, lower power consumption, et cetera. This cooler is powered by 24 VDC and is compatible with the TC-24-10, TC-24-12, and the TC-24-25 series temperature controllers. |  |
| Model CP-110 Capacity Rating: 110 watts at a 0 °C temperature difference Example Applications: Laboratory instruments, laser diodes, medical products, and cooling corrosive liquids with an optional stainless-steel liquid exchanger. Features: This cold plate uses two large thermoelectric modules for cooling medium sized heat loads. The high efficiency bonded-fin heat sink keeps the cooler small yet effective. One stainless-steel liquid exchanger can also be attached for cooling of corrosive liquids (please inquire for this option). This cooler is powered by 24 VDC and is compatible with the TC-24-12 and TC-24-25 series temperature controllers. |  |
| Model CP-200 & CP-200 HT Capacity Rating: 200 watts at a 0 °C temperature difference Example Applications: Laboratory instruments, component test benches, high-power laser diodes, and cooling corrosive liquids with optional stainless-steel liquid exchangers. Features: Our largest standard cold plate uses six thermoelectric modules, a bonded fin heat sink, and extender blocks for large heat loads and improved cooling at low temperatures. A high-temperature version is also available (the heating temperature is extended from 70 °C to 100 °C). Additionally, two stainless steel heat exchangers can also be attached for cooling of corrosive liquids. All versions of this cooler are powered by 24 VDC (uses the PS-24-20 Power Supply) and are compatible with the TC-24-25, TC-36-25 RS232, and TC-48-20 series temperature controllers. |  |
| Model CP-200 TT, CP-218 TT & CP-200 HT TT Capacity Rating: 200 watts at a 0 °C temperature difference Example Applications: Table top applications where for laboratory instruments, component test benches, high-power laser diodes, and cooling corrosive liquids with optional stainless-steel liquid exchangers. Features: A table-top version of our largest standard cold plate series (above), these units have a shroud that encloses the fan and legs to allow air to enter over the table top. A high-temperature version is also available (the heating temperature is extended from 70 °C to 100 °C). All versions of this cooler are powered by 24 VDC (uses the PS-24-20 Power Supply) and are compatible with the TC-24-25, TC-36-25 RS232, and TC-48-20 series temperature controllers. |  |
