Union Elbow is a brass-based composite elbow joint designed specifically for intelligent temperature-controlled fluid systems. It combines PTC/PTCR materials with the brass structure to achieve an integrated pipeline connection and temperature protection.

 

 

1. New energy battery liquid cooling system

Problem: The right-angle bend of the cooling pipeline is prone to local overheating due to pump pressure fluctuations

Plan:

The PTCR module monitors the temperature at the elbow in real-time 65℃ automatically triggers resistance jump, reducing the coolant flow rate

Brass body heat conduction belt design (thermal conductivity≥120 W/m·K), balanced pipe wall temperature field

Case: A certain car company's battery pack module reduces the risk of thermal runaway by 37% (measured data)

 

2. Industrial hydraulic servo system

Problem: The sharp bend of the high-pressure oil pipe causes turbulent heating, and the traditional solution requires an external temperature sensor

Plan:

Built in PTC matrix locates hotspots and provides feedback to the controller through a 4- 20mA signal

45°version optimized flow channel design, reducing pressure drop by 55% (verified by CFD simulation)

Case: Injection molding machine hydraulic station, energy-saving by 12%, reduced downtime due to faults by 80%

 

3. Smart home underfloor heating system

Problem: Abnormal water temperature at the bend of the water separator, difficult to monitor

Plan:

Integrated WiFi module (optional), real-time monitoring of elbow temperature through mobile app

Self recovery feature to avoid repairing and breaking walls after winter frost cracking

Case: A European underfloor heating brand saw a 60% decrease in after-sales costs
