Cooling medium is a key component of the thermal management system for electric forklifts, which directly affects the operating stability of core power components in long-hour working scenarios. Unlike internal combustion forklifts, the thermal management system of new energy electric forklifts targets the heat dissipation of motors, battery packs and electric control components, so the application of cooling medium has different requirements in actual operation.

In practical selection scenarios, users are advised to choose cooling medium products specially adapted for new energy electric industrial vehicles, instead of using coolant products for traditional internal combustion engines blindly. Qualified electric forklift cooling medium usually has low electrical conductivity, which can avoid potential safety risks caused by accidental leakage touching electronic components. Users can also select products with corresponding freezing point according to the local annual minimum ambient temperature, to prevent the cooling medium from icing and damaging the conveying pipeline in low temperature winter environment.

In the daily inspection part of practical operation, operators can check the cooling medium level before the daily work shift, to confirm the liquid level is kept between the upper and lower standard scales on the expansion tank. If the liquid level drops obviously in a short period, users need to check the sealing performance of the whole cooling pipeline, to find out potential leakage points in time. It is not recommended to mix cooling medium of different components or different brands, as the chemical reaction between different formulas may reduce the heat dissipation efficiency and cause corrosion to the pipeline.

For the replacement operation of cooling medium, users can follow the cycle specified in the product operation manual. Before injecting new cooling medium, users need to completely drain all the old remaining medium in the pipeline, and flush the whole circulation loop with clean flushing fluid to remove the sediment inside. After injecting new cooling medium, users need to start the equipment and run it at no load for 10 to 15 minutes, and discharge all the accumulated air in the pipeline to avoid air blockage that affects the heat dissipation effect.
