  • Patent number: 11309771
    Abstract: A cooling jacket has cooling units coupled in a row. The cooling unit comprises a plate-shaped cooling unit body with flow channel, a socket joint extending from one end of the flow channel, and a spigot joint extending from one end of the flow channel. The spigot joint is fitted to the socket joint to connect the cooling units to each other. The socket joint has a spherical-shaped inner surface, and the spigot joint has a spherical-shaped outer surface that matches the inner surface of the socket joint to detachably connect the cooling units to each other and be rotatable about an axis orthogonal to a coupling direction of the cooling units. The socket joint and the spigot joint are provided with through-holes that penetrate through the socket joint and the spigot joint, respectively, to communicate with the flow channels of the cooling units.

  • Patent number: 10520117
    Abstract: A cooling pipe joint which enables easy fine adjustment of the length of a cooling pipe which extends from the cooling pipe joint. The cooling pipe joint is provided with a base part, a fastening member which is fastened to the base part, a deforming member which is arranged between the base part and the fastening member, and a first slanted surface which slants with respect to a center axis. This first slanted surface presses against the deforming member by the force of fastening the fastening member to the base part and makes the deforming member deform to a direction approaching the center axis.
