The team members of the Faculty of Mechanical Engineering of the Czech Technical University in Prague have been working together on projects at CERN for more than 22 years. Some work is related to cooling systems for the inner detector of the ATLAS experiment and to forward types of detectors. Such as TOTEM experiment, today incorporated under CMS as PPS2 and AFP ATLAS. Based on our prototypes, two cooling systems in the LHC tunnel have been implemented so far, namely a compressor cooling circuit with C3F8 refrigerant for TOTEM and the second system for the AFP project using AIRCOOLER-Split type units It was designed by us and worked for the last 5 years without failure and free of maintenance for needs of AFP forward detectors. We are starting work on systems for forward-type detectors to withstand increased luminosity conditions in the LHC tunnel to be expected after 2027. A substantial part of our paper is related to this ongoing research work and to the possibilities of variable 3D metal printed heat exchangers. These could be used for cooling forward detectors and their electronics under demanding operating conditions and limits given by their dimensions soon.
