Abstract

A cooling water connector includes a column with a circular hole at one end. An axial inlet and an axial outlet are formed at the bottom of the circular hole. The axial inlet has a first threaded hole along its axis, and the axial outlet has a second threaded hole along its length. The other ends of the first and second threaded holes extend to the other end of the column. A radial inlet is connected to the axial inlet. An inner column is located inside the circular hole, and a connecting hole and a drain hole are formed on the inner column. The connecting hole and the axial inlet are connected, and the drain hole and the axial outlet are connected. A core tube is connected to the connecting hole. An inlet pipe is threaded into the radial inlet, and an outlet pipe is connected into the radial outlet. A first end plug is connected to the first threaded hole, and a second end plug is connected to the second threaded hole. This invention improves the utilization rate of the column by setting the axial outlet in a crescent shape. Furthermore, the crescent shape design ensures that the wall thickness between the axial inlet and outlet is equal, preventing any impact on the incoming cooling.
