What is TEC cooling technology?

TEC Semiconductor cooling, also known as thermoelectric cooling, is based on the Peltier effect, which is a phenomenon where an electric current flowing through a junction of two dissimilar conductors creates a temperature difference across the junction. This effect is utilized in semiconductor cooling devices, commonly known as thermoelectric or Peltier modules.

The component of TEC

The fundamental component of a thermoelectric cooling system is the thermoelectric module, which consists of two ceramic plates sandwiching a series of semiconductor elements, typically made of bismuth telluride or other thermoelectric materials. These semiconductor elements are doped to create an n-type (electron-rich) and p-type (hole-rich) junction.

¿Como funciona?

When a direct current is applied to the thermoelectric module, electrons in the n-type material gain energy and move to the p-type material. This movement of electrons causes heat to be absorbed from the cold side (the side in contact with the object to be cooled) and transferred to the hot side (the opposite side). The absorbed heat is then dissipated into the surrounding environment through a heat sink or fan.

To enhance the cooling performance of thermoelectric modules, various techniques are employed, including optimizing the choice of thermoelectric materials, improving the module’s design, and incorporating additional heat dissipation mechanisms such as heat sinks or fans.

Advanced water-cooled & air-cooled system

Water-cooled Systems with TEC

The basic setup consists of several components: TEC modules, a water-cooled heat exchanger, a pump, and a control system.

• TEC Modules: These modules utilize the Peltier effect to create a temperature difference. They are placed in direct contact with the target area or applicator used in the cosmetic procedure. By applying an electrical current, the TEC modules can actively cool the treatment area.
• Water-Cooled Heat Exchanger: The heat generated by the TEC modules needs to be dissipated efficiently to maintain their cooling capacity. The water-cooled heat exchanger consists of water channels or pipes through which chilled water flows. The heat from the TEC modules is transferred to the chilled water, which carries it away, thereby cooling the TEC modules.
• Pump: A pump is used to circulate the chilled water through the heat exchanger. It ensures a continuous flow of water, facilitating effective heat transfer and cooling. The pump maintains the circulation of chilled water, enabling efficient cooling of the TEC modules.
• Control System: The control system monitors and regulates the temperature of the chilled water to maintain it within the desired range. It ensures precise temperature control and can be adjusted according to the specific requirements of the procedure and patient comfort.

Air-Cooled Cooling Systems with TEC

Air-cooled cooling systems utilize fans or blowers to dissipate heat from the TEC modules. These systems are often compact and portable, making them suitable for certain medical aesthetics applications.

• TEC Modules: Similar to water-cooled systems, TEC modules generate the cooling effect by utilizing the Peltier effect. They are placed in contact with the treatment area or applicator to actively cool the target area.
• Air-Cooled Heat Sink: Instead of a water-cooled heat exchanger, air-cooled systems incorporate a heat sink with fins or a cooling plate. The TEC modules are attached to the heat sink, and the airflow generated by the fans or blowers removes the heat.
• Fans/Blowers: Fans or blowers are employed to create airflow across the heat sink. The moving air carries away the heat generated by the TEC modules, effectively cooling them.
• Control System: The control system in air-cooled systems performs the same function as in water-cooled systems. It monitors and regulates the temperature to ensure precise control and optimal cooling performance.

Both water-cooled and air-cooled cooling systems combined with TEC technology offer advantages in medical aesthetics applications. They provide precise and controlled cooling, preventing thermal damage and enhancing patient comfort during cosmetic procedures. The choice between water-cooled and air-cooled systems depends on factors such as the specific procedure, equipment requirements, and portability considerations.
