Introduction Overview Function

How it works

In the thermal management system of electric vehicles, the coolant flow rate is regulated and the flow direction is automatically switched:

1) PTC heater + three-way valve to realize the switching of the heating pipeline of the passenger compartment or battery pack

2) Four-way valve to realize the cooling of the motor and electronic control

It is miniaturized and intelligently transformed on the basis of traditional electric valves

Main technical indicators:

Communication protocol: LIN 2.1

Operating temperature: -40~+120°C

Rated working voltage: 12VDC, voltage range 9~16V

Action time: ≤5S

Internal leakage: ≤20ML/min, 30kPA

External leakage: 4ml/min, 320Kpa

Rated flow: 600L/h 5Kpa

Degree of protection: IP67

The drive module and valve body are split structure

It adopts a bottom-mounted structure, and the bonnet is designed at the bottom of the valve body, which is slightly different from the electric control valve used by Liuqi

The main external dimensions and installation dimensions are consistent with those of Liuqi
