The effect of decontaminants on vehicle cooling system

Abstract

This study analyzed the performance of the water pump and radiator under process of as-it-is condition, contamination, and decontamination among three types of radiator, namely used, new, and new coated radiators. Contamination process is completed by spraying the mixture of fine clay and water onto the radiator’s surface for 30 layers Decontamination process is done by AirestecSdnBhd, a local company. Internal analysis covers replacing the cooling fluid with used radiator water, tap water and tap water with additive to run experiments. As result, water pump displays similar trends for each set of experiment and air flow velocity, and its highest efficiency is 8.20 %. For external treatment, the effectiveness after decontamination process for new coated radiator, new radiator and used radiator are 43.60%, 31.42% and 30.16% respectively. While for internal treatment, tap water with additive, tap water and used radiator water exhibits 31.79%, 31.42% and 28.98% of effectiveness. As a conclusion, decontaminants towards radiator are effective to increase the performance of the radiator, but no impact on the efficiency of the water pump.For internal treatment, cooling fluid with additive help enhance the radiator performance in cooling system.
