Laser aesthetic treatment devices work by directing specific wavelengths of laser light to heat target tissue, achieving purposes such as pigmentation treatment, scar removal, hair removal, skin rejuvenation, and fat reduction.

During operation, these devices generate significant heat. Inadequate cooling directly impacts the device's lifespan and can even cause skin damage. Traditionally, most laser treatment devices relied on natural air cooling, which has limited cooling capacity, provides suboptimal heat dissipation, and fails to achieve a skin-cooling (ice compress) effect at the treatment head.

Cooling the device's light source assembly and the air intake on the front of the heat sink via forced air is slow, resulting in poor temperature reduction, a negative user experience, and compromised hair removal efficiency and results. It can also lead to condensation (fog or water droplets), potentially damaging control circuit boards.

Therefore, achieving effective cooling for laser treatment devices, ensuring they do not overheat or burn skin during prolonged use, and enhancing user experience are critical for product improvement. Currently, thermoelectric cooling technology is widely used in cooling elements for aesthetic devices, especially for IPL (Intense Pulsed Light) hair removal handpieces.

Thermoelectric cooling, also known as thermoelectric or Peltier cooling, is a technology that emerged in the 1950s, intersecting the fields of refrigeration and semiconductor technology. It utilizes specialized semiconductor materials to form P-N junctions, creating thermocouples that generate the Peltier effect—a new refrigeration method using direct current.

It stands alongside vapor-compression and absorption refrigeration as one of the world's three major refrigeration methods. Thermoelectric cooling technology offers advantages like high temperature control precision, no noise, no pollution, and compact size. As the technology advances, its application benefits are increasingly recognized by the market.

HuaJing Temperature Control's Liquid-to-Air series thermoelectric cooling modules dissipate heat to air, use circulating liquid for refrigeration, and exchange heat with the target equipment to provide cooling capacity. They are typically used for cooling tissues during laser or microwave thermotherapy; cooling or heating in capillary electrophoresis and cooling high-power lasers and other sensitive electronic equipment.
