Thermoelectric Coolers for Handheld Cosmetic Lasers

Introduction

Handheld lasers have become a standard device in cosmetic surgery and medical spa applications. Handheld cosmetic lasers offer a wide range cosmetic benefits with minimal damage to the body and reduced patient recovery time. Even though thousands of microscopic laser beams make pinpoint contact with the skin, the process does not affect the surrounding tissue. However, lasers generate a significant amount of heat that must be quickly and efficiently dissipated to protect the patient, and the laser electronics.

DA-024-12-02 Direct-to-Air

The DA-024-12-02 is a Direct-to-Air Thermoelectric Assembly (TEA) that uses impingement flow to transfer heat. It offers dependable, compact performance by cooling objects via conduction. Heat is absorbed through a cold plate and dissipated thru a high density heat exchanger equipped with an air ducted shroud and brand name fan. It has a maximum Qc of 24 Watts when ΔT = 0 and a maximum ΔT of 44 °C at Qc = 0.

Thermoelectric Coolers and Assemblies for Medical Applications

Introduction

Medical lasers are designed for use in hospitals, outpatient surgical centers, and physician offices. They combine cutting, ablation, and coagulation properties for precise, virtually bloodless procedures; minimizing thermal damage to the surrounding tissue and increasing recovery time. They also sanitize the area through the heat of the laser, destroying any microbiological bodies that could lead to infection.

Medical & Cosmetic Lasers

Medical lasers are used in a broad range of surgeries, such as cosmetic, arthroscopic and general surgery. It combines cutting, ablation, and coagulation properties for precise, virtually bloodless procedures; minimizing thermal damage to the surrounding tissue and increasing recovery time. The heat of the laser also destroys any microbiological bodies that could lead to infection. Laser systems also generate waste heat, and require sophisticated cooling systems to remove this heat and keep the laser stable and operating at peak performance during operation.
