What is the car cooling pipe support assembly?
The automotive cooling pipe support assembly refers to the structural component used for fixing, supporting, and protecting the cooling pipes (or cooling pipelines) in the automotive cooling system. Its main function is to prevent the pipes from displacement, deformation, wear, or leakage due to vibration, thermal expansion and contraction, or external forces, thereby ensuring the stable operation of the cooling system.
According to the latest publicly available information, this type of component typically has the following functions and structural characteristics:
Fixing and Limiting : By using clamping, locking, or support methods, the cooling pipes are firmly fixed in the vehicle body or engine compartment to avoid deviation.
Buffering and Shock Absorption : Some designs include buffer layers, flexible connectors, etc., to absorb engine vibrations and reduce fatigue damage to the pipeline.
Protective Function : It may integrate heat insulation, anti-corrosion, flame retardant, etc., to enhance the durability of the pipeline in high-temperature and corrosive environments.
Easy Installation and Maintenance : It adopts a detachable structure (such as a split-type support), facilitating maintenance and replacement.
Typical structure examples
Wuhan Juhetiancheng Patent (CN223622463U): Uses toothed locking strips, clamping plates, and threaded adjustment structures to achieve quick clamping and anti-loosening .
Foton Daemler Patent (CN223791312U): Composed of two detachable half-slots, suitable for the fixation of cooling pipes in special space positions .
Mocheng Automobile Patent (CN223794790U): Combines a pipe clamp with a locking component to prevent the clamping from loosening, improving the reliability of the clamping connection .
These support components are widely used in the cooling systems of traditional fuel vehicles and new energy vehicles, being an important part for ensuring the sealing performance and system safety of the cooling fluid circulation.
The main function of the automotive cooling pipe support assembly is to fix, support, and protect the cooling pipeline , ensuring its stable operation under complex conditions. According to the latest publicly available information, its specific functions can be summarized as follows:
Preventing pipe vibration and displacement : Through adjustable support frames or combined fixed pipe clamps, the cooling pipe is reduced from the vibration caused by engine operation or vehicle movement, reducing noise and improving driving comfort .
Avoiding pipe deformation or damage : During the processing of bent pipes or use, the support component (such as the internal support mechanism) can prevent the collapse, wrinkling, or excessive thinning at the bending point, ensuring smooth circulation of the cooling fluid .
Maintaining the correct installation position : Ensuring that the cooling pipe is arranged according to the design path, preventing interference with other components, and optimizing the heat dissipation efficiency and system layout .
Enhancing connection reliability : Through locking components, teeth plates, locking assemblies, etc., to improve the anti-loosening ability of the fixation points, preventing cooling fluid leakage due to long-term vibration .
Adapting to lightweight and high safety requirements : Especially in new energy vehicles, the support component also needs to take into account the fixing spacing of the battery liquid cooling pipes (usually 150–200mm), flame retardancy, pressure resistance, etc., to enhance the overall safety of the thermal management system .
In conclusion, although the cooling pipe support assembly is an auxiliary component, it has a key impact on the sealing, durability, and thermal management efficiency of the cooling system.
There is no official standard term "cooling pipe support assembly" in the automotive cooling system, but based on the context and common industry expressions, "cooling pipe support assembly" is likely to refer to the fixing brackets, clamps, or support structures for the cooling pipes (such as upper and lower pipes, bypass pipes, etc.) , used to fix the position of the pipes and prevent vibration wear or bending deformation.
If such components fail, the common failure manifestations are:
Loose, displaced, or detached pipes
Damage or leakage of the pipes due to long-term friction
Breakage, aging, or failure of the support components or clamps
Common failure manifestations and handling suggestions
Cooling fluid leakage : Check if there is green, pink, or orange liquid seeping from the pipe joint, and check if the support/clip is loose or damaged. Abnormal engine temperature: If the hose is flattened or bent, it may obstruct the coolant circulation, causing the water temperature to rise.
Abnormal noise or vibration: Loose supporting parts may cause the hose to collide with other components, generating noise.
Maintenance suggestions
Stop immediately for inspection: When coolant leakage or abnormal water temperature is detected, stop the vehicle immediately to avoid engine overheating and damage.
Inspect the hose and supporting parts:
Check if the hose is aging, cracking, or bulging;
Inspect the clamps for rust, looseness or fracture;
Confirm if the support frame is deformed or missing.
Temporary treatment: Minor leakage can be temporarily sealed with coolant leak prevention agent, but this is only an emergency measure.
Replace components:
Aged hose should be replaced entirely;
Damaged clamps or supporting parts need to be replaced with original or compatible parts.
Regular maintenance: Check the cooling system pipes and fixings every 2 years or 40,000 kilometers to preventive replacement can reduce the failure rate.
If you cannot identify the fault point by yourself, or if the vehicle has already experienced water temperature alarm, rapid consumption of coolant, or emulsified engine oil, it is recommended to immediately contact a professional repair agency to avoid severe engine damage.
