Reliable cooling of electronics in modern medical technology

The electronics in an MRI device fulfil several critical functions, including the generation of a strong and homogeneous magnetic field, which is necessary for imaging. MRI electronics transmit and receive radio waves in radio frequency coils that stimulate and measure the resonance of hydrogen atoms in the body. The superconducting magnet used in magnetic resonance imaging, which requires extremely low temperatures, is cooled towards absolute zero using special refrigeration machines and helium.
For electronic cooling tasks in magnetic resonance imaging, we at EKL are your solution partner with a very wide range of products, manufacturing technologies and over 30 years of experience in innovative cooling technology.

In a computer tomograph (CT), the electronics fulfil several key functions: It controls the X-ray tube that generates the beams required for imaging, processes the signals recorded by the detectors and reconstructs images from them. The X-ray tube in the computer tomograph, especially the anode, must be cooled effectively to ensure efficient performance and a long service life. It is also important to cool the detectors, as they can react sensitively to heat, which would impair the image quality of the CT.

The electronics in surgical robots play a crucial role in the precise control and movement of the robotic arms. For complex surgical procedures in robotic operating theatres, these electronics must function reliably at all times. Electronic components process the data from the high-resolution cameras and sensors to provide the surgeon with a detailed view and control during the robotic operation. These components generate a lot of heat loss and require efficient, rapid cooling. The heat sources usually include the processors and power electronics, which are responsible for controlling the motors and processing the signals. Their cooling system must prevent overheating, which could impair the precision and reliability of the surgical robot.

In LED endoscopes, modern electronics improve image quality through advanced image processing algorithms that increase image sharpness and contrast. Powerful processors in the endoscope PC support diagnostic procedures using digital technologies and artificial intelligence. Good cooling is particularly necessary for the high-performance LEDs used in modern endoscopes, as these can generate a considerable amount of heat. EKL develops effective thermal management for you to optimise the interaction of endoscope + camera + PC so that temperatures do not exceed the permissible limits for medical devices.

High-performance electronics are required to control the laser intensity, the duration of the laser pulses and the monitoring of the safety systems. These precise control mechanisms are crucial for the effectiveness and safety of the treatments. Good cooling of all electronic components and the lasers prevents the performance from being impaired and the service life of your medical lasers from being shortened. In particular, the laser components, which can reach high temperatures, must be cooled quickly and effectively. EKL offers customised high-performance heat sinks for laser devices and laser coolers. They are usually based on cold air or liquid cooling to ensure safe operation of your laser technology within the permissible temperature corridor.

Precisely operating medical laboratory equipment is essential for modern diagnostics and medical research. Frequently used devices include centrifuges, which are used to separate substances of different densities, and thermal cyclers for the polymerase chain reaction (PCR), which is used to amplify DNA segments. EKL develops and supplies specific heat sinks for the electronic components in your laboratory equipment that generate a lot of heat loss during operation - such as high-performance processors in analysers. From our broad product portfolio of heat sinks, fans, heat pipes and liquid coolers, we work with you to select the perfect laboratory equipment cooling system that guarantees an ideal operating temperature and a long service life for your equipment.

Medical light and therapy devices are used in the treatment of various skin diseases, mood disorders and certain sleep disorders through phototherapy, which utilises specific wavelengths of light for therapeutic effects. Electronic components in the light device/therapy device often require cooling in order to dissipate the power loss of the components from the device to the environment.

From simple medical computers and mini Medic PCs in doctors' surgeries and operating theatres to servers, switches, routers and storage devices, modern electronic devices have become indispensable in the healthcare sector. Standards such as IEC 60601-1 provide a legal framework for the safety requirements for medical panel PCs and medical hardware in general. Reliable cooling of the many components that generate heat loss is our core expertise at EKL. The cost-optimised individual solution for your medical PC is our ambition.
