Electric locomotives are locomotives which is powered by overhead lines, third tracks, or onboard energy storage devices (such as batteries or supercapacitors).
Electric locomotives benefit from the high efficiency of electric motors, typically exceeding 90%. Regenerative braking can achieve additional efficiency, allowing for the recovery of kinetic energy during the braking process and re-transmission of electricity to the line.
Compared to diesel locomotives, electric locomotives are quieter because there is no engine and exhaust noise, and mechanical noise is lower. Electric locomotives are easier to operate on the track, reducing track maintenance. Electric locomotives can have higher power output than diesel locomotives, and they can generate higher short-term surge power to achieve rapid acceleration.
Electric locomotives are an ideal choice for frequently stopping commuter railway services. Therefore, electric locomotives are used on freight routes with consistently high traffic volume, or in areas with advanced railway networks.
When an electric locomotive is in operation, the electric motor and other electromechanical equipment will generate heat. If this heat is not dissipated in time, it will cause damage to the electromechanical equipment of the electric locomotive due to overheating, thereby affecting the transportation of the electric locomotive.
Liquid cool plate utilize the high specific heat capacity of water and the high thermal conductivity of aluminum to quickly absorb and dissipate heat from mechanical and electrical equipment. Compared to fans, Liquid cool plate do not produce noise, are quieter, do not generate additional heat, and are more environmentally friendly.
