The invention belongs to the technical field of aircraft thermal management, and particularly relates to an aircraft cold source cooperative use method and device. The method comprises the steps that S1, the ram air heat sink capacity is determined based on the airflow temperature of ram air and the flow of the ram air; s2, the fuel heat sink capacity is determined based on the fuel quantity, the fuel temperature and the reference temperature value; s3, determining the heat dissipating capacity demand of the airborne equipment; and S4, whether a ram air heat dissipation channel connected with the airborne equipment is opened or not is determined according to the heat dissipation capacity requirement of the airborne equipment, the ram air heat sink capacity and the fuel heat sink capacity, and/or whether a fuel heat dissipation channel connected with the airborne equipment is opened or not is determined. According to the invention, the heat dissipation capability of the airborne equipment is improved.
