PTC Liquid Water Heater New Energy Heating System

Short Description:

Pure electric vehicles is the inevitable trend of future auto development. In order to improve the driving comfort and market competitiveness of pure EV, assembling a set of air conditioning system is indispensable to pure EV. The air conditioning system of traditional fuel cars keep warm by engine waste heat. Because of pure EV is without engine. So how to heating for the air conditioning system design of pure electric vehicle has brought new challenges. The PTC water heater heating system is mature and safe heating system of pure EV. There was a huge loss of battery for this system, which shortens the driving range of pure EV. So develop a set of energy-efficient of the PTC water heater heating system has very important significance.

Product Description

Since new energy pure electric vehicles do not have an engine, they cannot use the waste heat of the engine as a heat source for heating and air conditioning. The heating system provides a heat source, and its overall structure is composed of a radiator (including a PTC heating pack), a coolant flow channel, a main control board, a high-voltage connector, a low-voltage connector, and an upper case. It is part of the thermal management system of new energy vehicles.

Advantages

New energy vehicle PTC water heater is a device that uses PTC heating elements to heat vehicle coolant. Its main function is to provide heat to the vehicle in a low-temperature environment, so that key components such as the engine, motor and battery can operate normally.

The PTC heating element is a self-recovery thermistor element, which has the characteristics of high efficiency, stability and reliability. When the current passes through the PTC heating element, a thermal effect will be generated, which will increase the surface temperature of the element and achieve the purpose of heating the coolant. Compared with traditional electric heaters, PTC water heaters have the advantages of power self-regulation and temperature stability.

In a low temperature environment, the PTC water heater adjusts the heating power and temperature by controlling the magnitude of the current to keep the vehicle's coolant within a suitable temperature range and ensure the normal operation of key components such as the engine, motor and battery. At the same time, the PTC water heater has high heating efficiency, which can heat the coolant to an appropriate temperature in a short period of time, shorten the warm-up time of the vehicle, and improve driving comfort and safety.
