Definitions

  • the present disclosure relates to magnetrons that generate microwaves.
  • the fastener is disposed between the pair of pipe joints, and a discontinuous part between both ends of the cooling block facing each other extends in a tilted manner in the annular direction of the cooling block relative to the flow direction of the cooling liquid at a connecting part of the pair of pipe joints and circulation passage.
  • the fastener passing the discontinuous part extends in a direction tilted in a face perpendicular to the flow direction of the cooling liquid at the connecting part of the pair of pipe joints and circulation passage.
  • the fastener is engaged with both ends of the cooling block facing each other, and pushes an inner peripheral face of the cooling block toward the outer peripheral face of the anode cylinder by tightening and narrowing a distance between both ends.
  • the pair of pipe joints are provided on the outer peripheral face of the cooling block to communicate with the circulation passage.
  • the fastener extends in a direction perpendicular to the discontinuous part in the first embodiment.
  • the embodiment enables to further uniformly tighten the cooling block and the anode cylinder, and thus further reliable tightening becomes feasible.
  • the fastener extends in a direction parallel to a plane including the annular direction of the cooling block in the first embodiment.
  • the embodiment enables to further reliably tighten the cooling block and anode cylinder, compared to a case of extending the fastener in a direction tilted relative to a plane including the annular direction of the cooling block.
  • space S is set to, for example, about 3 mm before being tightened.
  • cooling block 10 in the exemplary embodiment also offers high flexibility in setting the extending direction of fastener 15.
  • the exemplary embodiment refers to the case that pipe joints 14a and 14b have a straight shape with the Y direction in the longer-hand direction.
  • the present disclosure is not limited to this structure.
  • a range of shapes e.g., L shape
  • the flow direction of the cooling liquid at the connecting parts of pair of pipe joints 14a and 14b and circulation passage 9 and the longer-hand direction of pipe joints 14a and 14b match the Y direction.
