Laird Thermal Systems offers a broad range of thermal management solutions for the medical industry to address heat issues and precise temperature control of medical devices, imaging and diagnostic systems.
Medical samples are typically stored in a refrigerator, and then moved to a temperature-controlled storage chamber closer to the test equipment while awaiting analysis. Storage chambers used with mass spectrometers, liquid chromatography, and protein analyzers are generally small units that are stacked on top of one another to save bench space. Temperature control inside the sample storage chamber is important, as temperature fluctuations can influence the interaction between the sample components and the adsorbents. The thermoelectric cooler assembly cooling units are designed with size, efficiency, cost, and continuous reliable operation in mind. Additional design factors include speed of cooling response, temperature stability, resilience against temperature cycling, and resistance to damage by moisture intrusion. Space-saving thermoelectric cooler assemblies optimize storage chamber cooling performance thanks to monitoring and alarm capabilities, low noise, higher efficiency and greater reliability.

Reagents are used in medical diagnostics to help analyze liquid samples obtained from patients to diagnose an illness. Cooling reagent chambers below ambient is critical to extend life of reagents and keep replacement costs down. Thermoelectric coolers refrigerate the reagents to extend their life and keep costs down.

Medical lasers are medical devices that use precisely focused light sources to treat or remove tissues. Lasers use compact thermoelectric coolers and assemblies to keep laser optics stable and at peak operating performance. This is achieved by controlling the operating temperature of the medical laser within defined parameters. The use of thermoelectrics provide reliable solid-state operation with no vibration to ensure long life operation with low maintenance requirements, resulting in lower total cost of ownership.

The PowerCycling Series is a thermoelectric cooler designed for thermal cycling between medical imaging systems, providing detailed images of the body structure in multiple topographies. Detailed contrasts are visible between the different soft tissues and are useful in neurology, cardiology and oncology. CT and PET Scanners use ion radiation created by X‐rays to capture topographical images and MRI’s use magnetic and radio frequency fields. During operation, components such as amplifiers and power suppliers generate a large amount of heat that needs to be managed within the system. Thermal management systems that feature liquid cooling offer higher efficiencies than air‐based heat transfer mechanisms. This translates into higher reliability, less field maintenance, higher system uptime and lower total cost of ownership.
