Application of PTC heater in automobile
Water heaters should have more opportunities. Because it takes into account the needs of battery heating and defrosting heating heating, the staggered battery heating time period, charging phase and static parking phase. Although air heating is the mainstream. At this time, the probability of turning on the air conditioner is relatively small. When the user is using the air conditioner, it is generally in a driving state. At this time, the battery basically does not need to be heated, so the heating demand of the whole vehicle can be met with a high-power water heater. With CAN communication and PWM energy consumption can be effectively controlled.
The new type of water and electricity integrated heating water tank provides a new material to enhance the defrosting effect, which should dispel most people's doubts. The principle is to convert the heating water tank into a water heater, a water tank type water heater. The latest and currently considered the best heating method for PTC heaters has the advantages of low water resistance and high heat exchange efficiency, but the disadvantage is the common faulty welding of the heating water tank. The PTC installed on the cold water plate is used for battery heating. The water circuit is welded to the aluminum plate. The aluminum plate between the water pipes is pasted and fixed with the PTC heating element. This heating method is not complete water heating, but more like a water cooling and heating The boards are joined together.
