Claim Text:
1. A thermal management system for an electric vehicle, comprising a device for cooling one or more heat generating components and a heat pump device, a first air-cooled heat exchanger, and an in-cabin heat exchanger wherein the heat pump device comprises a compressor, a first heat exchanger, a throttling element and a second heat exchanger, which are connected in the sequence listed through a first set of pipelines which form a first loop such that refrigerant is circulated through the first set of pipelines, the heat pump device further comprises a reversing element for controlling a flowing direction of the refrigerant, wherein the first heat exchanger is a dual channel exchanger having a first channel and a second channel, and the second heat exchanger is a dual channel exchanger having a first channel and a second channel, each of the first and second channels of each of the first and second heat exchangers being sealed and isolated respectively, wherein the first channel of the first heat exchanger and the second channel of the first heat exchanger are fluidly isolated from each other, wherein the first channel of the second heat exchanger and the second channel of the second heat exchanger are fluidly isolated from each other, wherein the first channel of the first heat exchanger and the first channel of the second heat exchanger communicate with other components of the heat pump device through the first set of pipelines, the device for cooling one or more heat generating components communicates with the second channel of the first heat exchanger through a second set of pipelines to form a second loop which can be shut off, the device for cooling one or more heat generating components communicates with the second channel of the second heat exchanger through a third set of pipelines to form a third loop which can be shut off, and the first air-cooled heat exchanger communicates with the device for cooling one or more heat generating components through a fourth set of pipelines to form a fourth loop which can be shut off, the in-cabin heat exchanger communicates with the second channel of the second heat exchanger and the device for cooling one or more heat generating components through a fifth set of pipelines respectively to form a fifth loop which can be shut off, wherein only one of the second, third, fourth, and fifth loops is not shut off at any given time, and then one or more heat generating components can always be cooled.
