摘要	A cooling system (100) for an imaging device (10) having a light source for exposing a media in which the cooling system (100) comprises a filter (124) for purifying coolant flowing through the cooling system (100) and a filter bypass (150) for limiting the purity of the coolant. In this way, the coolant, such as water, is prevented from becoming too pure, such that it begins to attack or etch the metal components in the coolant loop in the cooling system (100). This problem typically arises in the closed loop DI-filtered systems is that the water coolant becomes too pure. It is known that if water becomes more pure than approximately 10 MegaOhms (MΩ), referring to the water's resistance to electrical current which increases with increasing purity, the water can actually begin to etch metal such as copper in copper pipes of the loop.
其他摘要	一种用于成像装置（10）的冷却系统（100），其具有用于暴露介质的光源，其中冷却系统（100）包括用于净化流过冷却系统（100）的冷却剂的过滤器（124）和过滤器旁路（150）用于限制冷却剂的纯度。以这种方式，防止诸如水的冷却剂变得太纯，使得其开始侵蚀或蚀刻冷却系统（100）中的冷却剂回路中的金属部件。这个问题通常出现在闭环DI过滤系统中，水冷却剂变得太纯。众所周知，如果水变得比大约10兆欧姆（MΩ）更纯净，指的是水对电流的抵抗力随着纯度的增加而增加，水实际上可以开始在环路的铜管中蚀刻金属，例如铜。
