Abstract
A system for cooling plungers which operate in high pressure pumps. The system uses a plunger having a blind bore formed therein. The blind bore may receive a number of different objects, some of which are fixed to the plunger. A heat exchanger may be installed within the blind bore. The heat exchanger may have internal passages or openings which allow for the circulation of fluid within the blind bore, thus cooling the plunger. The heat exchanger may be formed of a material having a higher thermal conductivity than the material used to form the plunger. This allows the heat exchanger to cool the plunger more effectively than if the plunger were solid or filled with an empty air space. The heat exchanger may be sealed within the bore of the plunger, or exposed.
