[0002] With the rapid development of the new energy vehicle industry, consumer demand for new energy vehicles is increasing, driving the rapid iteration and updating of new technologies in the field. Integrated and compact design has become the mainstream development direction in the new energy vehicle sector, and integrated modules are bringing integrated design into a new design paradigm.

[0003] The original design had a high-temperature and high-pressure area and a low-temperature and low-pressure area in the integrated module refrigerant side flow channel plate. Without isolation between the two areas, heat transfer would be severe and affect system efficiency. In the original design, the isolation was mainly achieved by machining, milling out the insulation groove or wire cutting out the insulation groove. This method greatly increased the processing cost of the flow channel plate and affected the processing cycle efficiency. Utility Model Content

The sixth docking port is connected to the inlet of the first set of the regenerator. The third flow channel loop is interconnected with the fifth and sixth docking ports respectively.

[0009] Preferably, the flow channel plate is also provided with interface seven, interface eight and interface nine on its side, and a fourth flow channel loop is provided inside the flow channel plate.
