3. General Specifications (Environment Conditions) 3.3 Heat Radiation Countermeasures The following shows an example of calculation applied to heat radiation countermeasures for the operation panel. Because heat will accumulate in the upper portions of the unit, install an agitating fan as required. Display unit 200 (Agitating fan) 500 260 140 120 600 (1) Calculation of unit heating value Heating value (W) Total heating value of units (W): 28W (= control unit + display unit + keyboard unit + operation panel I/O unit) Total heating value (W) by machine input (D1): 5.6W (= 24V; total heating value when the 32 points are simultaneously turned ON × 7.3mA × 32) ... 24V; current consumption per point of the operation panel I/O unit DI ÷ 3.3kΩ ≒ 7.3mA Total heating value W = 33.6W (28 + 5.6) 9
3. General Specifications (Environment Conditions) 3.3 Heat Radiation Countermeasures (2) Calculation of operation panel cooling capacity Tolerance value for temperature rise (Δt) Panel internal temperature (according to each unit’s specification) T ≤ 55C° Panel peripheral temperature (according to machine’s specification) Ta ≤ 45C° Tolerance value for internal temperature rise ΔT = 10C° (T – Ta) Heat radiation area (A) The surface of the molded unit, which has lower radiation capacity than the metal plate surface, should be excluded for the heat radiation area in principle. The bottom of the operation panel, which has difficulty in radiating due to the temperature distribution, should also be excluded for the heat radiation area in principle. Heat radiation area A = 0.71mm 2 (≒ 0.6 × 0.12 + 0.6 × 0.5 × 2 – (0.26 + 0.14) × 0.2 + 0.12 × 0.5 × 2) (Top surface) (Front, rear surface) (Unit surface) (Both sides surface) Operation panel cooling capacity (W1) Calculate the cooling capacity to keep the temperature rise in the operation panel less than 10°C. Cooling capacity W1 = 42.6W (6 × A × ΔT) (3) Comparison of heating value and operation panel cooling capacity The operation panel cooling capacity is over the heating value, which presumed no need to install the heat exchanger. (4) Confirmation with the actual machine The result of the calculation above is only a rough indication. The actual temperature rise may differ according to the structure of the operation panel. Be sure to confirm the temperature rise value in the operation panel when the machine is running. 10
