1. Working Principle
The electric water heater heats the liquid through an electric heating element (such as a PTC ceramic element or thermal film heating technology). The heated liquid flows through the heater pipe through a circulating water pump, transferring the heat to the heat exchanger (such as a heater) inside the vehicle compartment, thereby achieving interior heating. In addition, the electric water heater can also be used to preheat the battery pack to improve the performance of the battery in low temperature environments.
2.Main functions
In-vehicle heating: In cold weather, quickly heat the interior of the vehicle compartment to improve riding comfort.
Battery preheating: In low temperature environments, heat the battery pack to ensure its working performance and life.
Defrosting and defoggering: By heating the liquid heating system, frost and fog are quickly removed from the front windshield and side windows.
Auxiliary heating: Used in conjunction with traditional fuel heating systems to provide additional heat, especially in extremely cold environments.
3. Product application
This product is a liquid heater, specially designed for pure electric buses. PTC coolant heaters rely on on-board power to provide heat for pure electric buses. The rated voltage of the product is 600V and the power is 20KW, which can be adapted to various pure electric bus models. The heating power is strong, providing sufficient and sufficient heat, providing a comfortable driving environment for drivers and passengers, and can also be used as a heat source for battery heating.
This product can be used alone to replace traditional oil-fired liquid heaters to achieve complete energy saving, emission reduction and cost reduction. In extremely cold areas, considering the lack of electricity, it can assist the use of traditional oil-fired liquid heaters. The use method is to connect the pure electric heater and the oil-fired heater in series, and confirm whether it is necessary to increase the water pump according to the actual demand to improve the circulation efficiency.
