1. A closed-loop liquid cooling system comprising:
a liquid coolant conduit in proximity to a heat-generating electrical component, the liquid coolant conduit allowing circulation of a liquid coolant to extract heat from the heat-generating electrical component, the liquid coolant conduit including an inner portion that surrounds and contains the liquid coolant, the liquid coolant including an outer portion configured to prevent or inhibit leakage of the liquid coolant from the inner portion and also detect any leakage from the inner portion, the outer portion of the liquid coolant conduit including a liquid detect sensor and a leakage/spray prevention shell;
at least one cold plate in thermal communication with the liquid coolant;
at least one pump configured to transport the liquid coolant in the liquid coolant conduit; and
at least one heat exchanger coupled to the liquid coolant conduit to extract heat therefrom,
wherein the inner portion of the liquid coolant conduit is a metal tube,
wherein the leakage/spray prevention shell includes polyvinyl chloride (PVC), polyethylene terephthalate (PET), ethylene propylene diene monomer (EPDM), or any combination thereof,
wherein the liquid detect sensor includes an external braided component and a plurality of internal braided components, each of the plurality of internal braided components includes and surrounds an electrode located therein.
