Abstract

The application belongs to the technical field of aircraft thermal management, and particularly relates to a skin temperature regulating system based on heat storage and a control method thereof. The skin temperature regulating system based on heat storage drives a power unit to send fluid heated by an onboard heat source or a cold side of an onboard heat source heat exchange channel into a skin heat exchange unit through a fluid circulation channel, so as to realize temperature regulation of the skin. After the fluid completes heat exchange in the skin heat exchange unit, the fluid is sent into the onboard heat source or the cold side of the onboard heat source heat exchange channel again. The skin temperature regulating system based on heat storage can also send fluid cooled by an onboard cold source or a hot side of an onboard cold source heat exchange channel into the skin heat exchange unit through the fluid circulation channel, so as to realize temperature regulation of the skin. After the fluid completes heat exchange in the skin heat exchange unit, the fluid is sent into the onboard cold source or the hot side of the onboard cold source heat exchange channel again. The application can meet the skin temperature control requirement, improve the ability to cope with extreme environmental conditions, and has flexible control and strong adaptability to the onboard cold source and the onboard heat source.
