These devices are intended for heat dissipation of electronic control elements in a controlled way, by using liquid CO2 at the temperature of e.g. -40 0C, which flows through the nano-pipes placed in electronic systems absorbs the produced heat. The liquid CO2 takes the heat and returns as vapour to the monoblock through the cable (transfer line), it is directed then to an exchanger, where it becomes condensed by a factor R407. In the liquid form, sucked up by the pump, it is pressed in to the installation again, through the monoblock (connection box) for cooling the electronics. Due to the fact that CO2 occurs in liquid form, it is a closed system. The system uses throttle valves made of austenitic steel 1.4404, manufactured in our company, which find application in controlling the flow of liquid CO2 at the temperature up to -600 0C.
"Marta” is a device which makes it possible to dissipate heat of 400W at using the liquid CO2 and which will become almost a series product used for science institutes. The first presentation of the Marta project at the conference in Bonn raised considerate interest of many science institutes in Europe, carrying out research on decay of particles. The first presentation of Marta project during conference in Bonn raised considerate attention of many science institutes in Europe dealing with research on decay of particles.
The second device developed for CERN is the so-called „Baby Demo” of heat power of 9200 W, which is currently in design stage. For building the elements of the “Monoblock”, “Connection Box” and “Local Box” and elements of piping installation steel of austenitic structure 1.4404 was used. Product and design cooperation with CERN resulted in new products and technologies which will be used in the future projects of this institute.
