Title: Innovations by Terry L. Brown in Refrigeration Technology

Introduction

Terry L. Brown is an accomplished inventor based in San Diego, California. He has made significant contributions to the field of refrigeration technology, particularly in the development of miniature refrigeration systems. With a total of two patents to his name, his work has the potential to impact various applications in medical and industrial settings.

Latest Patents

Terry's latest patents include a "Precooling system for Joule-Thomson probe," which describes a miniature refrigeration system and method of operation. This innovative system utilizes a primary refrigerant that is pressurized by a compressor to a relatively low pressure for safety reasons. The compressed primary refrigerant is then passed through a primary-to-secondary heat exchanger to precool the gas mixture. The secondary side of this heat exchanger is cooled by a secondary refrigeration system. The primary refrigerant exits the primary outlet of the heat exchanger and flows to a primary Joule-Thomson expansion element, where it is expanded to a lower temperature. This low-temperature gas is designed to cool a heat transfer element mounted in the outer wall of a catheter or cryoprobe, effectively cooling surrounding tissue.

Another patent by Terry is also titled "Precooling system for Joule-Thomson probe," which details a miniature mixed gas refrigeration system. This system formulates an optimum gas mixture from a group of component fluids based on calculated thermodynamic properties. The gas mixture is pressurized by a compressor and passed through a primary heat exchanger and a primary-to-secondary heat exchanger for precooling. The system is designed to solidify and trap liquid contaminants, ensuring a clean gas mixture for efficient cooling.
