After the calculation is completed, the heat sink is simulated and optimized. The temperature of the optimized heat sink parameter scheme can be reduced by 2 ° C, and subsequent attempts to optimize other parameters of the heat sink have no good effect. Try to open the air vent on the middle partition board and design an air duct independent air duct system. Figure 11 shows the temperature variation curves of the optimized two air duct systems and the original machine solution. The optimization scheme (opening a double-row round hole with a diameter of 4 mm on the partition). For the original machine plan and optimize the temperature values ​​of each measuring point of the air duct system, the temperature change curves of the measuring points of each program tested in the paper are compared. As can be seen from the figure, both schemes reduce the temperature of each measuring point. In particular, scheme 2 can reduce the temperature of each measuring point by 3~4 °C. When the temperature rise of electronic components is high, this scheme can be considered. 1 Analyze the air duct, electronic heat dissipating components and heat sink of the inverter outdoor unit through CFD simulation calculation method, estimate and calculate the thermal power consumption of the four main electronic heat dissipating components, and finally walk through the simulation analysis process. ; 2 When calculating the power consumption of the calibration component, you can first set a rough range value based on experience, and then perform calculation and check, which can save simulation time and cost; 3 Experimental tests were carried out on several heat sinks with good simulation optimization results. The temperature change trend of each measuring point is basically consistent with the experimental test. It shows that the CFD simulation calculation of electronic heat dissipation has certain accuracy and can provide directional guidance for the design. 4 For this kind of inverter outdoor unit, although the middle partition hole can reduce the temperature of each electronic component (about 3 °C), it also increases the interaction between the low-frequency noise on the fan side and the high-frequency noise on the compressor side, which deteriorates the noise. Sound quality. Therefore, when the temperature of the electronic components under the operating conditions of the inverter outdoor unit is too high, this method can be considered to achieve the cooling; when the temperature rise of the electronic components under the operating conditions of the inverter outdoor unit is normal, this method is not recommended. .
