Abstract
A method of and apparatus for cooling equipment including exposing a fluid to a tool comprising electronic components at a temperature T and pressure P, compressing the fluid to a temperature T1 and pressure P1, exposing the fluid to a surface in communication with liquid or gas or both external to the tool wherein the fluid after exposure to the surface is at a temperature T2 and pressure P2, and allowing the fluid to expand to a temperature T3 and pressure P3 wherein the equipment is a tool in a subterranean formation and T is less than T2 and P is less than P2. Apparatus and methods for cooling oil field services tools including a fluid that conducts heat from the tool to the fluid, a compressor that, a heat exchanger that accepts fluid from the compressor and that rejects heat from the fluid, and a valve or orifice.
