Function

• Coolant Flow Control: This three - way valve is mainly responsible for controlling the flow path of the coolant in the HVAC system. When the battery needs to be heated, the coolant flows through the W - PTC (heating element) and the water - cooled plate close to the battery under the control of the three - way valve to achieve the purpose of heating the battery. When the battery needs to be cooled, the three - way valve changes the flow path of the coolant, allowing the coolant to flow through the chiller to exchange heat with the air - conditioning refrigeration circuit and cool the battery. In addition, it also plays a role in the cooling loop of the motor, electronic control unit, and charger, controlling the coolant to flow through the low - temperature radiator to dissipate heat.
• Temperature Regulation: By precisely controlling the flow rate and direction of the coolant, the three - way valve helps to accurately regulate the temperature inside the vehicle cabin. Whether it is heating in cold weather or cooling in hot weather, it can ensure that the air - conditioning system provides a comfortable temperature environment for passengers.
