Thermal simulations give engineers a visual representation of the temperature and airflow inside the equipment. Thermal simulations enable engineers to design the cooling system; to optimise a design to reduce power consumption, weight and cost; and to verify the thermal design to ensure there are no issues when the equipment is built.
Cooling systems using liquids such as liquid metals, water, and stream [13] also actively manage high power LED's temperature. Liquid cooling systems are made up of a driving pump, a cold plate, and a fan-cooled radiator. [14] The heat generated by a high power LED will first transfer to liquids through a cold plate.
Thermal management can mean: Thermal management (electronics) Thermal management of high-power LEDs; Thermal management of spacecraft; Exhaust heat management of internal combustion engines; Thermoregulation in biological organisms; Thermostat, a thermal control and management device for heating and cooling systems
Immersion cooling is a promising thermal management technique to address these challenges. [26] Immersion cooling of batteries is specifically beneficial in abuse conditions, where the thermal propagation is needed to be avoided across the battery module or pack.
The thermal control subsystem can be composed of both passive and active items and works in two ways: Protects the equipment from overheating, either by thermal insulation from external heat fluxes (such as the Sun or the planetary infrared and albedo flux), or by proper heat removal from internal sources (such as the heat emitted by the internal electronic equipment).
Battery thermal management systems can be either passive or active, and the cooling medium can either be air, liquid, or some form of phase change. Air cooling is advantageous in its simplicity. Such systems can be passive, relying only on the convection of the surrounding air, or active, using fans for airflow.
The EATCS is capable of rejecting up to 70 kW, and provides a substantial upgrade in heat rejection capacity from the 14 kW capability of the Early External Active Thermal Control System (EEATCS) via the Early Ammonia Servicer (EAS), which was launched on STS-105 and installed onto the P6 Truss.

The polyacrylate hydrogel film [70] from the 2022 study has broader applications, including potential uses in building construction and large-scale thermal management systems. This research focused on a film developed for hybrid passive cooling.
