Cooling systems, devices, and related methods

A cooling system comprising:

• a plurality of refrigeration units, wherein each refrigeration unit of the plurality of refrigeration units comprise:
• a thermoelectric element in thermal communication with a heat exchanger;
• a fluid pump in fluid communication with a fluid inlet and a fluid outlet;
• tubing positioned within each of the refrigeration units of the plurality refrigeration units, wherein the tubing connects the fluid inlet to the fluid outlet;
• a fluid cooling element in thermal contact with the thermoelectric element;
• a fan;
• and
• a temperature sensor positioned to detect a temperature of fluid within the tubing;
• wherein each of the refrigeration units of the plurality of refrigeration units is configured to comprise an independent closed-loop fluid circuit with a patient cooling device and a fluid cable and each of the refrigeration units of the plurality of refrigeration units are thermally independent from one another;
• and
• a control unit communicatively coupled with and configured to independently operate each of the refrigeration units of the plurality of refrigeration units, wherein the control unit comprises:
• a user interface;
• a power connector configured to provide power to the cooling system;
• a power controller configured to adjust cooling power of the plurality of refrigeration units;
• and
• a power switch;
• wherein the plurality of refrigeration units are configured to operatively interface with the control unit interchangeably at a plurality of discrete locations associated with the control unit;
• and
• wherein the fluid cable is configured to interface with at least one of the refrigeration units of the plurality of refrigeration units and the patient cooling device is configured to interface with the fluid cable.
