Chiller-less cooling system and method for interventional detector

摘要

The present invention provides a chiller-less cooling system and method for an interventional detector. A cooling method comprises using a heat pipe 12 to connect a tray 101 and a lift frame 102 of a detector housing 10 so as to reduce a thermal resistance between the detector tray 10 and the lift frame 102 and transfer more heat from the detector; using an external heat sink 13 connected with the heat pipe 12 so as to reduce a thermal resistance between the lift frame 102 and an ambient environment; and embedding a high heat transfer coefficient device 11 into the detector tray 10 so as to collect heat leading to the heat pipe 12, obtain a uniform temperature distribution, and reduce a thermal resistance of the detector tray 10. Another cooling method comprises using a loop heat pipe 14 to connect the detector tray 10 and a C-arm 20 of an interventional imaging system; embedding a condenser end 141 of the loop heat pipe 14 into the detector tray 10; embedding a evaporator end 142 of the loop heat pipe 14 into a heatspreader which is fixed onto the C-arm 20. The present invention further discloses a method for cooling a detector using a fan/heat sink/loop heat pipe module 30 in a C-arm 20.
