Bidirectional heat exchange system for automobile

The invention belongs to the technical field of automobile components, and provides a bidirectional heat exchange system for an automobile. The bidirectional heat exchange system comprises a main loop, a heating branch path and a cooling branch path, wherein the heating branch path and the cooling branch path are arranged in parallel; the main loop comprises a water cooling plate which is fitted on a device to be subjected to heat exchange, and a first port and a second port of the water cooling plate are respectively located at the two ends of the device to be subjected to heat exchange; the main loop further comprises a reversing module which controls liquid of the water cooling plate to flow between the first port and the second port, one end of the reversing module is connected with a second end, and the other end of the reversing module is connected with a first common end of the heating branch path and the cooling branch path; a second common end of the heating branch path and the cooling branch path is connected with a first end. According to the bidirectional heat exchange system for the automobile, the reversing module is additionally provided, so that the temperature difference of two ends in a process of heating or cooling a battery pack is reduced, the heating or cooling efficiency is improved, and the regular operation of the battery pack is ensured.
