Space vehicle comprising cooling system

A space vehicle, comprising:

• one or more heat-producing components;
• and
• a closed loop cooling system configured to remove heat generated by the one or more heat-producing components, the closed loop cooling system comprising
• a coolant passageway defining a closed loop,
• a hydrocarbon coolant located within the coolant passageway, wherein the hydrocarbon coolant is in a single liquid phase through the coolant passageway,
• one or more pumps configured to move the hydrocarbon coolant through the coolant passageway,
• a first heat exchange component disposed along the coolant passageway, the first heat exchange component configured to transfer heat from the heat-producing components of a payload to the hydrocarbon coolant, and
• a second heat exchange component disposed along the coolant passageway, the second heat exchange component configured to remove heat from the hydrocarbon coolant.

A space vehicle, comprising:

• a payload comprising one or more heat-producing components;
• and
• a vehicle platform comprising a closed loop cooling system configured to remove heat generated by the one or more heat-producing components of the payload, the closed loop cooling system comprising
• a coolant passageway defining a closed loop, the coolant passageway comprising a platform coolant passageway portion and a payload coolant passageway portion,
• a hydrocarbon coolant located within the coolant passageway, wherein the hydrocarbon coolant is in a single liquid phase through the coolant passageway,
• one or more pumps configured to move the hydrocarbon coolant through the coolant passageway,
• a first heat exchange component disposed along the payload coolant passageway portion, the first heat exchange component configured to transfer heat from the heat-producing components of the payload to the hydrocarbon coolant,
• quick disconnect fittings coupling the platform coolant passageway portion to the payload coolant passageway portion, and
• a second heat exchange component disposed along the platform coolant passageway portion, the second heat exchange component configured to remove heat from the hydrocarbon coolant.
