Description

Technical Field

[0001] The utility model relates to the technical field of automobile pipelines, in particular to a warm air return pipe component. Background Art

[0002] The main function of the heater return pipe is to provide a coolant return channel for the heater, ensuring the circulation of coolant between the engine and the vehicle heater. It is usually connected between the vehicle heater and the engine water pump and is an important component of the cooling system.

[0003] Since the distance between the heater and the engine water pump on the vehicle body is relatively far, and the layout of other engine parts must be taken into consideration, the heater return pipe is usually long and has a strange shape. Therefore, the heater return pipe is usually designed from an overall structure to a segmented structure of metal pipe-hose-metal pipe to reduce the manufacturing cost and difficulty of the metal pipe. However, the segmented heater return pipe mainly relies on the metal pipe to connect with the vehicle body. After the overall length of the metal pipe is shortened, it is also necessary to consider the fixing requirements between the vehicle wiring harness to meet the fixing requirements of the compact space of multiple staggered pipelines. In order to solve this problem, the existing technology sets multiple wiring harness brackets on the metal pipe to support and fix the pipelines in the space, and sets multiple connection brackets connected to the vehicle body to support and fix the metal pipe. However, this arrangement will result in too many brackets, and it is difficult to arrange multiple wiring harness brackets, and it is impossible to arrange multiple wiring harnesses in the space.
