Abstract
In a radiation image detecting apparatus having its image receiving means constituted of a two-dimensional array of composite radiation detecting units each of which includes a radiation sensor and a signal processing circuit, the composite radiation detecting units are provided with circuit cooling means for suppressing heat generation at the above signal processing circuits. The circuit cooling means consists only of piping in thermal contact with the composite radiation detecting units, or consists both of the the piping or the duct-and-coolant intakes combination and of porous-walled gas piping stretched through the clearances left between two adjacent composite radiation detecting units constituting the two-dimensional or the one-dimensional composite radiation detecting unit array. The piping and the duct-and-coolant intakes combination are supplied with a liquid coolant, while the porous-walled gas piping supplied with a gaseous coolant. The gaseous coolant turbulently leaks out through the porous wall of the gas piping and drives away heat stagnation in the above clearances.
