Estimating the term…
The present invention is a cooling plate including a groove, which becomes a passage of a coolant, inside a body, wherein one or more fins are provided inside the groove, wherein the groove is covered with a lid having width larger than the groove, wherein the lid is joined to the body by friction stir welding, and wherein a weld bead formed by: the joining is outside the passage, and the weld bead formed by the joining is formed within the body and further, is characterized by a manufacturing method of a cooling plate that has a first groove, which becomes a passage of a coolant, and a second groove, which has width larger than the first groove and receives a lid on the first groove, inside a body, receives the lid on the second groove, and is joined to the body, the manufacturing method of a cooling plate wherein, while the lid and the body are joined together by the friction stir welding owing to insertion of a-rotation tool having a shoulder and a pin, the joining is performed so that a weld bead formed by the joining may become out of the passage, and furthermore, is characterized in that a target for sputtering is joined to the cooling plate.
A manufacturing method of a cooling plate that has a first groove, which becomes a passage of a coolant, and a second groove, which has width larger than the first groove and receives a lid on the first groove, inside a body, places the lid on the second groove, and is joined to the body, comprising joining the lid and the body together by friction stir welding owing to insertion of a rotation tool having a shoulder and a pin so that a weld bead formed by the joining may become outside the passage while the joining is performed.
A manufacturing method of a cooling plate which has a groove, which becomes a passage of a coolant, inside a body, and in which a lid is joined to the groove, comprising joining the lid and the body by friction stir welding owing to insertion of a rotation tool which has a shoulder and a pin, and making the groove be a left-hand side to a traveling direction of joining when the rotation tool rotates to the left, and a right-hand side to a traveling direction of joining when the rotation tool rotates to the right while joining the lid and the body.
A manufacturing method of a cooling plate which has a groove, which becomes a passage of a coolant, inside a body, and in which a lid is joined to the groove, comprising joining the lid and the body by friction stir welding owing to insertion of a rotation tool which has a shoulder and a pin, and setting a center of the rotation tool in a position which is apart from an edge of the groove by a radius of the pin or more.
A manufacturing method of a cooling plate which has a groove, which becomes a passage of a coolant, inside a body, and in which a lid is joined to the groove, comprising joining the lid and the body by friction stir welding owing to insertion of a rotation tool which has a shoulder and a pin, wherein a joining direction where the rotation tool rotates is a direction opposite to a rotational direction of the rotation tool when the joining direction by the rotation tool passes a curve while joining the lid and the body.
A manufacturing method of a cooling plate which has a groove, which becomes a passage of a coolant, inside a body, and in which a lid is joined to the groove, comprising joining the lid and the body by friction stir welding, wherein joining becoming a folding of the joining is made to be joining by two straight lines while joining the lid and the body.
A manufacturing method of a cooling plate which has a groove, which becomes a passage of a coolant, inside a body, and in which a lid is joined to the groove, wherein a joining of the body and the lid has a projection thicker than other sections, comprising joining to the projection by friction stir welding owing to insertion and movement of a rotation tool having a shoulder and a pin.
A manufacturing method of a cooling plate which has a groove, which becomes a passage of a coolant, inside a body, and in which a lid covers the groove, comprising joining the lid to the body by friction stir welding, and providing an air vent in a portion forming the passage while the lid and the body are joined by friction stir welding.
A manufacturing method of a cooling plate which has a groove, which becomes a passage of a coolant, inside a body, and in which a lid covers the groove, comprising joining the lid to the body by friction stir welding, and forming at least an end portion of the joining out of the joining while the lid and the body are joined by friction stir welding owing to insertion of a rotation tool which has a shoulder and a pin.
