1. Relationship between motor cooling water channel and flow rate

The flow rate of motor cooling water channel is directly related to the cooling effect: the larger the flow rate, the more heat is taken away per unit time, and the better the cooling effect; However, excessive flow will increase the workload of the system pump and need to be matched with the waterway structure design. 1. The influence of flow rate on cooling effect: Flow rate is positively correlated with heat dissipation capacity: an increase in coolant flow rate can quickly remove the internal heat of the motor, preventing overheating of the winding and iron core and wheel hiding. For example, high-power motors often adopt high flow designs (such as 10-20 liters per minute) to cope with high thermal loads. The risk of insufficient flow: If the flow rate is too low (such as below 70% of the design value), the temperature rise of the coolant may be too high, which may cause insulation material aging or even burn the motor

2. The restriction of the water channel structure on the flow rate: the larger the cross-sectional area, the stronger the flow capacity, but the flow rate needs to be balanced - a large cross-sectional area may lead to a low flow rate, which in turn reduces heat transfer efficiency. The diameter of the waterway is usually designed to be 5-15 millimeters (adjusted according to the size of the motor). Waterway layout resistance: Excessive bending or long flow channels can increase hydraulic resistance, and the required flow rate needs to be maintained by increasing pump pressure (such as 0.2-0.5MPa). Optimizing design (such as reducing sharp turns and using spiral channels) can reduce resistance. 3. Key parameters in desig

n and operation. Target flow calculation: It needs to be calculated based on the motor loss power (kW) and the allowable temperature rise of the coolant (usually ≤ 10 ° C), formula: flow rate (L/min) ≈ motor loss power (kW) × 0.86/coolant temperature rise (° C). Actual flow monitoring: It is recommended to install a flow meter to ensure that the actual flow rate is not less than 85% of the design value, to avoid cooling failure due to blockage or decreased pump efficiency. Water quality management: Scale or impurities can clog waterways, and regular water quality testing (such as hardness ≤ 50mg/L) and filtration are required. Summary: Flow and waterway design need to be optimized synergistically - high flow can improve cooling efficiency, but it needs to be matched with low resistance waterway structure and sufficient pump power; Continuous monitoring of flow is required during actual operation to prevent blockage and failure.

2. Research on Cooling in Injection Molding Process

Cooling research in injection molding process mainly focuses on mold temperature control, cooling circuit design, coolant selection, and pipeline layout. The following is a specific analysis: The importance of mold temperature control is to control the heat transfer rate: the mold temperature controls the heat transfer rate. After the hot plastic melt is injected into the cold mold cavity, it comes into contact with the mold steel and begins to cool until the product is ejected at the end of molding.

. The temperature difference between the mold and the melt affects heat transfer, and maintaining a constant mold temperature is crucial for consistent heat transfer efficiency, which in turn affects injection consistency, including
