What Causes a Car Fan Fuse to Blow?
1 Answers
Electric vehicle battery cooling fan fuses often blow due to excessive current. Relevant information about car fans is as follows: 1. Function: Primarily used for engine heat dissipation and coolant cooling to prevent engine failure caused by overheating. The car engine must be adequately cooled in high-temperature working environments to maintain optimal operating temperatures, ensuring good performance, durability, and meeting exhaust emission requirements. The engine cooling system plays a key role here, mainly consisting of components such as the cooling fan, radiator, and thermostat. 2. Principle: To avoid engine overheating and ensure cooling effectiveness, components around the combustion chamber (cylinder liners, cylinder heads, valves, etc.) must be properly cooled. The car cooling system typically consists of a radiator, thermostat, water pump, cylinder block water passages, cylinder head water passages, and fan. The radiator is responsible for cooling the circulating water, with its water pipes and fins mostly made of aluminum. The aluminum water pipes are flat-shaped, and the fins are corrugated, emphasizing heat dissipation performance. The installation direction is perpendicular to the airflow direction to minimize wind resistance and maximize cooling efficiency. The coolant flows inside the radiator core, while air passes outside it. The hot coolant cools down by dissipating heat to the air, while the cold air warms up by absorbing the heat from the coolant, making the radiator a heat exchanger.
