Title:
VOLTAGE TRANSFORMER FOR MACHINE TOOL, AND MACHINE TOOL HAVING THE SAME
Document Type and Number:
Japanese Patent JP2016047579
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a voltage transformer and a machine tool having the same in which a transformer can be sufficiently cooled when it is mounted to the machine tool.SOLUTION: A voltage transformer 20 is mounted to a machine tool having an air blowing mechanism that generates airflow for cooling a heat source. The voltage transformer comprises a transformer 30 and a body 21 in which the transformer 30 is stored. The body 21 comprises: a connection part 29 connected to a flow channel of the airflow after cooling, which is generated by the air blowing mechanism; an intake port 26a formed in a side plate 26, where the connection part 29 is provided, to take the airflow after cooling to the inside; and an exhaust port 23a provided in a bottom plate 23 and formed so as to exhaust the airflow taken from the intake port 26a through the flow channel which is in contact with the transformer 30.SELECTED DRAWING: Figure 4
