MEDICAL APPLICATIONS

The medical industry offers diverse and unique thermal challenges, requiring the consideration of a wide range of thermal technologies. For example, surgical equipment may only need to dissipate a couple of Watts, but the spatial limitations and touch temperature requirement compound the thermal challenge considerably. Other, large scale equipment could need to dissipate 100s of kWs and may need to consider component temperature control as well as system energy consumption.

ACT has experience in a wide range of applications including:

  1. Imaging Systems Thermal Control
  2. PCR Devices
  3. Diagnostic Equipment
  4. Surgical Devices
  5. Test and Measurement Equipment
  6. Laser diodes
  7. Sample Transportation Containers

Examples of Thermal Control in the Medical Industry

Examples of Thermal Control in the Medical Industry by Advanced Cooling Technologies Imaging equipment, such as CT scanners, require extreme levels of temperature control. The sensors and components in these systems provide better results when operating at uniform temperatures to adjacent components. Most sensors operate on a duty cycle as the angle and orientation with respect to the patient changes. In many cases, the mounting plate nor metallic heat spreader are able to maintain adequate temperature uniformity across its length. ACT has designed and implemented heat pipes in imaging devices to enhance thermal conductivity while passively controlling temperature across the contact surface of the sensors. This not only provides better cooling and consistent operating temperatures, but increases the image quality.

Examples of Thermal Control in the Medical Industry by Advanced Cooling TechnologiesPolymerise Chain Reaction (PCR) devices are used routinely in the medical industry to diagnose various imperfections within blood samples. These devices were used significantly during the COVID-19 pandemic to provide reliable testing and diagnosis. Thermal cycling is an important process in the operation of PCR and the transient responsiveness is a key feature. Some of the most capable devices utilize specialized vapor chamber technology to achieve this rapid response. Vapor chambers can take point loads and rapidly spread the heat across a larger surface, allowing all sample wells of the PCR to rapidly cool or heat.

Examples of Thermal Control in the Medical Industry by Advanced Cooling TechnologiesSample containers have fairly unique thermal requirements based on the specimen being transferred or stored. In many cases, the containers must maintain an active coolant to control the temperature to the level of precision required. As the containers grow in size, the thermal challenge of maintaining temperature becomes more and more challenging, often exceeding the capabilities of off the shelf chillers and vapor compression systems. ACT’s expertise in designing active systems has supported our customers’ ability to meet some of the most challenging requirements in temperature control for this segment of the medical industry.

Electronics Control Equipment is important to the operation of many key medical equipment. In most cases, these electronics cabinets are maintained in well air-conditioned rooms, however they must maintain a rated (NEMA or IP) seal to avoid moisture or debris from damaging the long-term operation of the electronics. In these cases, above-ambient Enclosure Coolers such as ACT’s Heat Sink Cooler (HSC) provide a low cost, readily available product option that can easily be integrated, increasing both the reliability and longevity of these systems.
