Abstract
A cooling oil circuit (D) circulates cooling oil over an x-ray tube absorbing its waste heat. A refrigeration circuit (E) then cools the cooling oil. A heat buffer (52) absorbing peak heat loads from the cooling fluid when the x-ray tube is generating x-rays. Valves (58, 60) regulate a relative amount of cooling oil entering the heat buffer to increase heat transfer efficiency. The heat buffer enables the system to handle peak heat loads with a smaller, more condensed refrigeration system, by absorbing heat during operation of the x-ray tube and releasing heat between operations.
