Abstract

Claims (7)

1. A remote heat removal system for removing heat from a first fluid maintained in a hazardous environment, comprising:

a heat exchanger positioned within the hazardous environment within proximity to the first fluid, the heat exchanger having a primary side in heat exchange relationship with a secondary side with the first fluid in fluid communication with the primary side;

a remote reservoir located outside of the hazardous environment, containing a second fluid at a temperature below a temperature of the first fluid, with the second fluid in fluid communication with the secondary side of the heat exchanger;

a first pump operable to drive at least a portion of the second fluid through the secondary side of the heat exchanger, with the first pump positioned outside of the hazardous environment;

a hydraulic fluid transport mechanism having a first section in fluid communication with the second fluid and a second section in fluid communication with the first fluid, with the first section fluidly isolated from the second section, the first section being configured to have the second fluid drive a second pump, which drives the first fluid through the second section; and

wherein the hydraulic fluid transport mechanism comprises the second pump having a first impeller located in the first section that is driven by the second fluid and a second impeller located in the second section that is driven by the first impeller and in turn drives the first fluid over the secondary side of the heat exchanger.

2. The remote heat removal system of claim 1 wherein the first fluid is a gas and the second impeller is a fan that drives the first fluid over the secondary side of the heat exchanger.
