Thermal - Thermoelectric, Peltier Modules

OT1.5-31-F2A thermoelectric cooling module has been widely adopted in various kinds of heating and cooling applications due to its main advantages. Firstly, it is simple in construction with superior temperature control and is able to be wide temperature range. With one side working as cold side while the another side generate heat, OT1.5-31-F2A module can offer steady and solid cooling performance. Secondly, no external power supply is necessary for it to work properly under the circumstances that the modules have an adequate thickness. Lastly, it is also easier to use and maintain.

OT1.5-31-F2A Module Application Fields

OT1.5-31-F2A thermoelectric cooling module is widely used in many fields, such as medical, pharmaceutical, industrial control, laser, security detection, automobile electronics, household appliances, etc.

• Medical: It is used for cooling medical devices, such as medical laser.
• Pharmaceutical: It helps to lower temperature in pharmaceutical lab and bottle shipments.
• Industrial Control: It is applied for laser cutting and welding, precision die cutting, soldering, and etc.
• Laser: It is used for cooling tight mark precision laser welding and laser marking.
• Security Detection: It used for laser marking, binding, lens detection, security and fire prevention, liquid crystal display.
• Automobile Electronics: It helps to cool automotive electronics as the temperature inside the car usually changes for a few months.
• Household Appliances: It is applied for cooling air-conditioning, microwave oven, laundry washing machine, dish washing machine, refrigerator and etc.

OT1.5-31-F2A Module Working Principle

OT1.5-31-F2A thermoelectric cooling module has two parts: the hot side and the cold side. Both parts are assumed to be hollow cylinders in this paper. To make a closed thermoelectric cooling system, the top and bottom of both the hot and cold sides should remain closed. The heat exchange process takes place between the hot and cold sides.

When an electric current passes through these two cylinders, the temperature difference between the two sides will be amplified. The top side of the hot side will be hotter while the bottom side of the cold side will be colder. The heat will be absorbed from the hot side and transferred to the cold side. This thermoelectric cooling process forms the working principle of OT1.5-31-F2A module.

The thermoelectric cooling is not limited by the size of the object to be cooled or heated. In this way, it can be used for cooling small areas to large ones. In addition, due to its superior cooling performance, it is able to achieve a wide temperature range, which is suitable for many applications.
