Peltier Cooler


SKU: 000285 Categories: , Tags: , , ,


A Peltier cooler, also known as a thermoelectric cooler or TEC, is an innovative and solid-state cooling device that utilizes the Peltier effect to create a temperature differential across its surface. This temperature differential enables the device to transfer heat from one side to the other, making it a valuable tool in various cooling and heating applications.

Key Features:

Solid-State Operation: Peltier coolers have no moving parts, making them reliable and low-maintenance. This solid-state operation distinguishes them from traditional refrigeration methods.

Electrically Driven: They are powered by an electrical current, typically using a direct current (DC) power source. Reversing the current direction allows for both cooling and heating operations.

Compact Design: Peltier coolers come in various sizes, with a compact design that suits a wide range of applications, from small electronic devices to industrial systems.

Rapid Temperature Control: These devices can quickly achieve temperature changes, making them suitable for applications that require precise temperature control.

Energy Efficiency: Peltier coolers can be energy-efficient in certain situations, particularly when used for small-scale cooling and heating tasks.

No Refrigerants: They do not use refrigerants or compressors, making them environmentally friendly and reducing the risk of leaks.


Electronics Cooling: Peltier coolers are used to cool electronic components, such as CPUs and laser diodes, preventing overheating and extending the lifespan of devices.

Thermal Management: They play a crucial role in thermal management systems in laboratories and industrial settings.

Medical Devices: Peltier coolers are used in medical equipment to maintain precise temperatures for samples and diagnostic devices.

Food and Beverage: These coolers are employed in portable coolers and beverage coolers for camping and outdoor activities.

Photonic Devices: Peltier coolers are used in laser diode modules and photonic equipment for temperature stabilization.

Aerospace: They are utilized in aerospace applications, including cooling sensitive components in spacecraft and satellites.

Peltier coolers are versatile devices, valuable for both cooling and heating applications. Their solid-state operation, compact design, and precise temperature control make them essential components in various industries, from electronics and healthcare to aerospace and beyond.
