Cold Plate Coolers (13)
Cold plate coolers are usually the best method of cooling an object when the object can be attached directly to the cold plate. The direct contact allows the heat to be efficiently conducted to the thermoelectric (Peltier) modules. This keeps the system operating as efficiently as possible and improves the stability and accuracy of temperature control.
Air Coolers (9)
Air coolers, sometimes called air-to-air heat exchangers, are the best choice for cooling electrical enclosures and refrigerated cabinets containing objects that can not be easily cooled by direct contact to a cold plate. There may be irregularly shaped components, parts that need freedom to move, or objects that do not have any one good surface from which to remove heat. While not as efficient as the direct contact of a cold plate, air coolers are ideal in these cases because the cooled air adapts to any and all shapes within the cabinet.
Liquid Coolers (3)
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.
Peltier - Thermoelectric Cooler Modules (122)
TE Technology’s high quality Thermoelectric or Peltier Cooling Modules (also known as a TEC or a TEM) are offered in High-Performance and High-Temperature varieties as well as a wide variety of standard types and sizes. While typically used for cooling, they can also be used for heating (by reversing the electric current flow) and even power generation.
Temperature Controllers (12)
TE Technology offers numerous temperature controllers for cooling-only applications as well as heating and cooling applications. Our temperature controllers use fast pulse-width modulation to provide control that does not cause harmful thermal cycling of the thermoelectric (Peltier) device as can happen when using common on/off type controllers. TE Technology controllers offer various computer interfaces including USB, RS-232 and RS-485 communications.
Standard Coolers and Temperature Controllers Catalog
Thermistors are the temperature sensors used for all TE Technology controllers.
Thermistors are used to provide:
• feedback/control for the primary control loop,
• as a secondary over-temperature safety sensor with most of our controllers, or
• for monitoring secondary system temperatures.
They can replace the primary sensor that is included with each temperature controller or be used on the secondary thermistor input which is available on all controllers except the TC-24-10.
Selection is based on physical characteristics and temperature range. Be sure to use a thermistor that is compatible with the particular controller being used. Not all controllers have every resistance-versus-temperature curve available.
The lead wires can be lengthened if necessary (within a reasonable amount) using standard copper wire of any gauge recommended for the controllers; special alloy wire is not necessary.
Power Supplies (9)
TE Technology offers a line of economical power supplies for use with our thermoelectric coolers and temperature controllers. These power supplies are all compact switch-mode designs with 115/230 VAC 50/60 Hz operation. They feature overload, over voltage and short circuit protection and are shipped ready to use with the AC power cord attached.
