An x-ray tube for emitting x-rays which includes an anode assembly and a cathode assembly is disclosed herein. The x-ray tube includes a vacuum vessel, an anode assembly disposed in the vacuum vessel and including a target, a cathode assembly disposed in the vacuum vessel at a distance from the anode assembly, and a heat pipe is supported relative to the anode assembly. The cathode assembly is configured to emit electrons which hit the target of the anode assembly and produce x-rays. The heat pipe transfers thermal energy away from the target through the vacuum vessel. The heat pipe provides for greater thermal transfer down the bearing shaft of the anode assembly, thereby providing greater cooling of the anode assembly.
