How to calculate the power of die casting aluminum heater?
Calculation method of cast aluminum heater power.
First of all, the calculation of heating power should pay attention to the following three aspects:
1. Heat loss in the system
2. Power at starting
3. Power during operation
Second, consider the following worst cases when calculating:
1. Maximum operating temperature
2. The shortest operating cycle
3. The lowest ambient temperature
4. The maximum weight of the heating medium (the flow medium is the maximum flow)
Third, the steps of cast aluminum heater power design:
1. According to the process, draw the heating process flow chart (not involving material form and specifications).
2. Calculate the heat and time required for system startup.
3. Calculate the heat required for the process.
Fourth, consider the appropriate safety factor to determine the total power of the cast aluminum heater.
1. Determine the power supply and control system of the cast aluminum heater.
2. Determine the sheath material and power density of the heating element.
3. Determine the form, size and quantity of cast aluminum heaters.
