Transmission Oil Cooler line

    information to be updated

The Transmission Oil Cooler Line is a piping system connecting the automatic transmission and the transmission cooler. Its core function is to circulate automatic transmission fluid. Designed and manufactured specifically for modern, high-performance automatic transmissions, it is a critical thermal management component. This product maintains transmission temperatures within the optimal operating range, effectively preventing premature oxidation and failure of ATF and eliminating the risk of overheating and wear of internal components.

Product Features:
Efficient Heat Dissipation
Optimized internal wall finish and bend radius ensure minimal ATF fluid circulation resistance and maximum flow rate, maximizing cooling efficiency.

Adaptable to Extreme Environments
The pipe body features a chemically resistant synthetic rubber inner layer, a high-strength fiber or wire braided middle layer, and an ozone- and aging-resistant outer layer. This eliminates the aging and rust-clogging issues of traditional rubber hoses and metal hoses, while also improving resistance to vibration fatigue.

Leak-Proof Safety
Engineered with either integrated snap-fit ??or patented push-fit connectors, the connection is secure and easy to install, and features double or multiple O-ring seals.

Flexibility and Ease of Installation
The pipe shape is custom-made to original equipment (OE) specifications, perfectly fitting the complex spaces of the vehicle chassis and engine compartment. Wide Range of Vehicle Coverage
Flexible use of steel, aluminum, or composite hoses allows for tailored fit to meet varying pressure and vibration absorption requirements.

News and Information

Transmission Oil Cooler line Industry knowledge
In the technological iteration of automotive transmission systems, the popularization of?high-performance automatic transmissions?has brought significant thermal management challenges: frequent gear shifts of transmissions in urban congestion can cause a sharp rise in ATF (Automatic Transmission Fluid) temperature. Under extreme working conditions, traditional cooling lines are prone to aging and leakage, insufficient heat dissipation efficiency and other issues, which in turn lead to premature oxidation of ATF, wear of internal components, and ultimately transmission failures.
JIATIAN Transmission Oil Cooler Line, as a core thermal management component specially designed for modern high-performance automatic transmissions, accurately targets industry pain points. With core technologies such as efficient heat dissipation, extreme environment resistance and leakage prevention, it builds a stable thermal cycle protection system for transmissions, serving as a key technical solution to solve transmission thermal management problems.

I. Basic Cognition: Core Connection Between Transmission Thermal Management and Cooler Lines

1. Definition of Core Concepts

Concept Professional Definition
Transmission Oil Cooler Line A piping system connecting the automatic transmission and the transmission cooler, whose core function is to realize directional circulation of ATF and complete heat exchange
ATF Thermal Management A technical system that prevents ATF oxidation failure and overheating wear of internal transmission components by controlling ATF temperature within the optimal range (usually 80-90℃)
Pipeline Weather Resistance The ability of pipelines to maintain structural integrity and performance stability under complex environments such as high and low temperatures, corrosion and vibration
JIATIAN's customized forming process (matching OE specifications) enables the pipeline to perfectly adapt to the complex space of the vehicle chassis/engine compartment, ensuring no bending and blockage in the circulation path and guaranteeing the efficient operation of the thermal management closed loop.

II. Core Technology: Key Industry Indicators and Technical Advantages of JIATIAN Products

1. Key Industry Technical Indicators and JIATIAN Product Performance

Key Industry Indicators Industry General Standards JIATIAN Product Parameters Technical Selling Point Support
Heat Dissipation Efficiency Pipelines must ensure ATF flow rate ≥2L/min and heat exchange efficiency ≥60% ATF flow rate increased by 15% and heat exchange efficiency reached 72% Optimized inner wall finish and bending radius reduce circulation resistance and maximize flow rate
Temperature Resistance Range -40℃ to 120℃ -50℃ to 150℃ Outer ozone aging-resistant material + inner chemical corrosion-resistant rubber, suitable for extreme temperature environments
Sealing Reliability Static sealing without leakage for ≥5000h Static sealing without leakage for ≥8000h Integrated snap-fit/patented push-fit connectors + double O-ring seals to eliminate leakage risks
Vibration Fatigue Resistance Can withstand 10-2000Hz vibration with cycle times ≥10^6 times Can withstand 5-3000Hz vibration with cycle times ≥2×10^6 times Middle layer of high-strength fiber/steel wire braid enhances vibration fatigue resistance

2. Technical Comparison Between Traditional Pipelines and JIATIAN Pipelines

Pipeline Type Material Structure Core Defects Technical Breakthroughs of JIATIAN Pipelines
Traditional Rubber Pipeline Single-layer rubber + metal joints Prone to aging and cracking, poor temperature resistance, and joint falling off under vibration Three-layer composite structure (inner corrosion-resistant + middle vibration-resistant + outer aging-resistant) eradicates aging problems
Traditional Metal Pipeline Single steel/aluminum pipeline Difficult to bend, prone to rust and blockage, and poor adaptability Supports customization of steel/aluminum/composite materials and OE specification forming to adapt to complex installation spaces
Relying on the industry-leading water expansion bellows technology of its own R&D center and CNC fully automatic pipe bending equipment, JIATIAN can achieve high-precision customization of pipelines and ensure the stable achievement of technical indicators from the production end.
