US 11,309,771 B2 · Cooling jacket and cooling unit

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.
