Medical equipment is becoming more and more powerful, how to deal with heat dissipation and electromagnetic compatibility issues

      Medical equipment is increasingly associated with artificial intelligence, machine learning and the Internet of Things. As the connections between devices become closer and more data collected, patients, healthcare professionals, and medical device manufacturers will all benefit from it. At the same time, the accuracy and stability requirements of medical equipment are also higher.    

      Ensuring the safety and normal performance of medical equipment is very important and challenging. 

      Challenges facing medical equipment   

      In order to improve the performance of medical equipment, it is necessary to improve the efficiency of the equipment to send and receive signals and the processing capacity of equipment information, which leads to an increase in heat load and more electromagnetic interference.    

      Since electromagnetic interference and heat are interrelated, the radiator can help reduce the heat load. However, electromagnetic interference may be aggravated.    

      Solving these two major challenges at the same time ensures that manufacturers deal with electromagnetic interference and heat issues in a way that maximizes product performance.

      Overall solution for medical equipment   

      Considering the factors affecting heat, electromagnetic interference and sensitive structure of the equipment from the overall and early stage, the reasonable application of thermal interface materials, absorbing materials and electromagnetic shielding materials that reduce electromagnetic interference can detect defects as early as possible and bring the equipment to the market faster.    

      There are many materials that can be used for thermal management of medical equipment, such as thermal interface materials: thermal pads, thermally conductive phase change materials, thermally conductive gels, etc.

      Compared with heat dissipation, medical electronic equipment needs to solve the problem of electromagnetic interference. Most of the medical equipment is low-frequency interference, and some absorbing materials can be used. And more often use electromagnetic shielding materials, such as: conductive rubber, conductive foam, shielding cover, shielding ventilation plate, conductive cloth tape, copper foil tape and so on.

      Before the complete layout of the circuit board, by evaluating various device components under the background of the large system in the early design stage, design engineers can optimize the limited space in the device to solve electromagnetic interference, Challenges in heat dissipation and structural design.
