Description

Technical Field

[0001] The present invention belongs to the technical field of new energy vehicles, and in particular relates to an automotive thermal management system integrated component and a preparation method thereof. Background Art

[0002] At present, the automotive thermal management system pipelines, whether traditional models, hybrid models, or new energy pure electric models, still use traditional hose + clamp connections, nylon tube + quick-plug connections, or TPV pipeline connections. They are all designed for single pipeline and interface connection, single pipeline processing and manufacturing, and single pipeline installation and fixation to the vehicle body. With the current increasingly compact interior layout requirements and modular vehicle design trends, traditional pipelines are becoming increasingly difficult to adapt, often resulting in complex and redundant structural designs, more inconvenience in loading and subsequent interference, and other problems. There are also pipeline integration forms in the prior art, but the prior art solutions generally perform integral injection molding on the runner plate or pipeline module, and then assemble parts such as water pumps and water valves, such as Fig.15 As shown, the water pump and the water valve are connected to the injection molded base plate by bolts. This solution is generally limited to the integrated module. This solution is more limited in terms of product size specifications and demolding direction, and has high requirements for product shape accuracy. Otherwise, parts such as the water pump and the water valve will be difficult to match for subsequent assembly. Summary of the invention

[0003] In view of the above problems existing in the prior art, the technical problem to be solved by the present invention is to provide an automotive thermal management system integrated component and a preparation method thereof, which integrates pipelines and related parts, reduces the occupied space and is easy to install.

[0010] Furthermore, the functional components are arranged in the integrated board.

[0011] Furthermore, the number of the water valve, water pump and sensor is more than one.
