  The cooling water pipe switching unit 53 can be provided with a branching function so that the flow rate can be switched in a plurality of stages. For example, when the first stage is configured to the fourth stage, the first stage has a flow rate of 100%, the second pipe has a flow rate of 0%, and the second stage has a first level. The flow rate of the pipeline: 70%, the flow rate of the second pipeline: 30%, in the third stage, the flow rate of the first pipeline: 30%, the flow rate of the second pipeline: 70%, in the fourth stage The flow rate of the first pipeline is 0%, and the flow rate of the second pipeline is 100%.

The first pipe line 5211 can be attached to the lower surface of the plate portion 511 by making the linear shape into a zigzag shape. In this case, it is needless to say that the shape of the groove between the pipe coupling bodies 5121 and 5122 matches the first pipe line 5211.
