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 T&#x3e;T, opening the solenoid valve SVand adjusting the electronic expansion valveto a preset initial opening degree; obtaining an update real-time temperature Tof the heat generating component after a setting time period; if the update real-time temperature T&#x3e;T, performing the following steps every set period of time, obtaining a refrigerant temperature refrigerant temperature Tat the inlet end of the refrigerant heat dissipation pipe and a refrigerant temperature Tat the outlet end of the refrigerant heat dissipation pipe; calculating a real-time temperature difference &#x394;Tof the inlet end temperature Tand the outlet end temperature T, wherein &#x394;T=T&#x2212;T, obtaining a preset target temperature difference &#x394;Tand calculating a deviation &#x394;T, &#x394;T=&#x394;T&#x2212;&#x394;T; calculating a deviation change rate &#x394;&#x394;T=&#x394;T&#x2212;&#x394;T, and adjusting the opening degree of the electronic expansion valve based on the deviation &#x394;Tand the deviation change rate &#x394;&#x394;T, enables the temperature difference between the inlet end and the outlet end of the refrigerant heat dissipation pipe reaches the target temperature difference so as to ensure a good heat dissipation effect and keep the heat generating component working in a good condition and also lowers the cost by using refrigerant for transferring heat from the heat generating component. With the method, the reliability and stability of the air conditioning operation are improved, and the problem of poor heat dissipation reliability and high heat dissipation cost in the prior art is solved.
