Abstract
An air conditioning heat dissipation structure control method and a system includes the steps obtaining a real-time temperature Te of the heat generating component; if Te>Ted, opening the solenoid valve SV2 and adjusting the electronic expansion valve 4 to a preset initial opening degree; obtaining an update real-time temperature Te of the heat generating component after a setting time period; if the update real-time temperature Te>Tmax, performing the following steps every set period of time, obtaining a refrigerant temperature refrigerant temperature Tin at the inlet end of the refrigerant heat dissipation pipe and a refrigerant temperature Tout at the outlet end of the refrigerant heat dissipation pipe; calculating a real-time temperature difference ΔTreal-time of the inlet end temperature Tin and the outlet end temperature Tout, wherein ΔTreal-time=Tout−Tin, obtaining a preset target temperature difference ΔTtarget and calculating a deviation ΔTdeviation, ΔTdeviation=ΔTreal-time−ΔTtarget; calculating a deviation change rate ΔΔTdeviation=ΔTdeviation−ΔTdeviation′, and adjusting the opening degree of the electronic expansion valve based on the deviation ΔTdeviation and the deviati…
