Cooling element

Abstract

Cooling element for vacuum pump comprising a base element wherein by the base element an internal void is defined. Further, an inlet is connected to the base element and is in fluent connection with the void. Further, an outlet is connected to the base element and in fluent connection with the void such that a coolant can flow from the inlet through the void to the outlet to dissipated heat. Therein, the base element is connected to a housing of a vacuum pump.
