AI Technical Summary

Technical Problem

Existing automotive thermal management systems have numerous and complex cooling pipes that are long and bulky. These pipes are prone to problems such as being too soft, difficult to shape due to their length, and easily bent. Furthermore, increasing the size of the aluminum pipes can lead to interference and vibration.

Method used

The system employs a piping and fixing mechanism that combines the inner and outer walls of the pipes. The piping mechanism includes clamps, fixing columns, springs, and clamping blocks, while the fixing mechanism includes a fixing frame, sleeve, and finned tube. By combining rubber hoses and rigid pipes using braiding and knitting processes, the pipe layout is optimized, and the strength and rigidity are enhanced. The clamps and fixing columns are used to adjust the position, the springs push the clamping blocks to clamp the cooling components, the fixing frame is connected to the sleeve through fixing holes, and the adjusting blocks adjust the tightness of the connection, thus achieving pipe stability and heat dissipation.

Benefits of technology

It achieves safe coolant delivery and noise reduction, improves pipeline stability and vibration resistance, optimizes cooling pipeline layout, enhances vehicle quality and safety reliability, and meets the needs of the automotive industry.
