On April 14, 2020, Huawei applied for new patents for powertrain and electric vehicles. The patent was published on February 12, 2021, and the publication number in China is CN212529295U.
According to this information, the specification shows that the power assembly includes: a motor controller including a housing; and a first functional unit that is arranged in the housing and can be used during operation and the heat exchanger Generate heat.
The heat exchanger is placed in a housing that includes a first circulation passage for cooling medium and a second circulation passage for circulating the second cooling medium, wherein the first circulation passage has a first external cooling surface and is connected to The first functional unit. Heat conduction is achieved at the first external cooling surface.
The first circulation channel has a second external cooling surface and conducts heat with the inner surface of the housing at the second external cooling surface. The powertrain and electric vehicle provided by this application can make full use of the external cooling surface of the heat exchanger.
- Improve the efficiency of heat exchanger utilization
- Improve the heat dissipation of the motor controller
- More compact structure
- Low space consumption
In addition, the document also emphasizes Huawei’s long-term “car-free” status, but focuses on ICT technology to help automakers manufacture high-quality cars and become smart network cars and incremental parts suppliers.
Huawei’s rotating chairman Xu Zhijun (openly) said: “Huawei does not produce cars, but it can help automobile companies produce high-quality cars.”
Based on previous information, Huawei’s goal is to help traditional manufacturers use the latest Huawei technology to develop better products.
