20150121922 | THERMAL MANAGEMENT SYSTEM FOR AN ELECTRIC VEHICLE - An electric vehicle thermal management system includes a dynamic heat dissipating unit, an air conditioner unit, a heat exchange unit, and a control unit. The heat exchange unit is connected to the dynamic heat dissipating unit and the air conditioner unit for transferring heat therebetween. The control unit adjusts the flow rate of a coolant in the dynamic heat dissipating unit for controlling and adjusting the heat dissipating ability of the dynamic heat dissipating unit to meet the heat dissipation of the system, thereby improving distribution and management of heat energy in the system. | 05-07-2015 |
