Automotive coolant line fittings are an important part of the automotive cooling system, and their main function is to transfer coolant between the engine, radiator, warm air system and other components, so as to effectively dissipate heat and heating. The following is a detailed description of automotive coolant line fittings:
Definition and Function
Coolant line fittings are the piping system connecting the engine, radiator, warm air system and other major components, transferring the heat generated by the engine work to the radiator for cooling by transmitting the coolant, and transferring the coolant after dissipating the heat back to the engine for the next heat cycle. In addition, the coolant piping is also responsible for transferring coolant to the warm air system to heat the cockpit.
Materials and construction
Ethylene-Propylene-Dimethyl-Diphenyl Rubber (EPDM): three-layer construction with an inner diameter of 15 mm and a wall thickness of 3.5 mm, with good heat resistance and aging resistance.
Thermoplastic dynamic vulcanized rubber (TPV): three-layer structure, inner diameter of 15mm, wall thickness of 2.5mm, with good elasticity and wear resistance.
Nylon (PA): three-layer structure, inner diameter of 15mm, wall thickness of 1.25 ~ 1.5mm, with light weight, easy to assemble, the advantages of small radial space occupation.
Design and Manufacturing Standards
The design of coolant piping needs to consider the following points:
Heat resistance: able to withstand the high temperature generated by the engine work.
Pressure resistance: able to withstand the pressure changes of the coolant in the circulation process.
Corrosion resistance: to prevent the coolant on the corrosion of the pipeline.
Flexibility: to ensure that the engine vibration can still work properly.
Lightweight: Reduce the weight of the whole vehicle and improve fuel economy.
Application Scenarios and Installation Methods
Coolant lines are widely used in the engine compartment, at the chassis and in the battery pack. According to the temperature, pressure and assemblage requirements at different locations, nylon materials and structure types with different temperature resistance levels are selected. For example, nylon piping can be used in the motor compartment, at the chassis and inside the battery pack. The specific forms include smooth pipe and corrugated pipe, and the connection methods include cold plugging and laser welding.
