Description

technical field

[0001] The invention relates to the technical field of medical imaging equipment, and more specifically relates to an air-cooled heat dissipation device for a PET system. Background technique

[0002] The detectors of the PET system are evenly distributed on the entire circumference of the ring, and the heat and power consumption is scattered. After the outer cover is covered, the internal air flow field is relatively chaotic, and the cold air from the outside cannot be well guided to the detector air inlet, and the detector air outlet comes out. The hot air cannot be effectively discharged to the outside of the housing, which will cause the temperature of the detector to be high and affect various performance indicators and image quality of the system. At the same time, the operation of CT will also affect the heat dissipation of the PET system. In the patent documents whose publication numbers are CN103860187B and CN105704982B, it is announced that a centr...
