The invention discloses a compression and cold-storage portable powerless refrigerating device with an externally-connected power source. The refrigerating device comprises an externally-connected driving device, a refrigeration phase-change processor, an indication control device, a heat exchange pipeline group and a heat exchange package plate box, wherein the externally-connected driving device is detachable and is connected with a gas-liquid conveying pump arranged on the refrigeration phase-change processor; one end of the gas-liquid conveying pump is connected with a low-pressure gas-liquid bin by virtue of a low-pressure one-way valve, and the other end of the gas-liquid conveying pump is connected with a high-pressure gas-liquid cold storage bin by virtue of a high-pressure one-way valve; the refrigeration phase-change processor is connected with the heat exchange package plate box by virtue of the heat exchange pipeline group so as to form a closed loop. The refrigerating device is convenient to disassemble and convenient to carry, needs an external power source, can adapt to rotary driving and linear driving, is capable of refrigerating instantly for any need at any environment and any place, is safe and environment-friendly, is low in cost, can automatically adapt to the shapes and sizes of to-be-refrigerated objects, and is direct in refrigeration and high in efficiency.
