1. A portable system for cold therapy with optional compression therapy, applied to a body wrap, comprising a cooling mechanism, a reservoir, and a control assembly; wherein the cooling mechanism comprises a compressor, a condenser, a fan, and a heat exchanger, and the control assembly is electrically connected to the compressor, and the fan, respectively; and wherein:
the compressor, the condenser, the fan, and the heat exchanger are placed outside the reservoir, respectively;
the compressor has an air inlet connected to the heat exchanger through a first tube;
the heat exchanger is connected to the condenser through a second tube;
the condenser is connected to an air outlet of the compressor through a third tube;
the first tube and the second tube are connected by fluid, and the second tube and the third tube are connected by fluid;
the fan has a working surface facing the condenser; and wherein,
the reservoir comprises a liquid outlet of the reservoir; the heat exchanger comprises an air inlet of the heat exchanger, an air outlet of the heat exchanger, a liquid inlet of the heat exchanger, and a liquid outlet of the heat exchanger;
wherein the air outlet of the heat exchanger is connected to the first tube, the air inlet of the heat exchanger is connected to the second tube, the liquid inlet of the heat exchanger is connected to the liquid outlet of the reservoir, the liquid outlet of the heat exchanger is connected to a liquid inlet of the body wrap, and a liquid outlet of the body wrap is connected to the liquid outlet of the reservoir and the liquid inlet of the heat exchanger;
wherein the liquid in the reservoir flows into the heat exchanger first through the liquid outlet of the reservoir and the liquid inlet of the heat exchanger, and then flows into the body wrap through the liquid outlet of the heat exchanger and the liquid inlet of the body wrap; the liquid in the body wrap can flow into the heat exchanger first through the liquid outlet of the body wrap and the liquid inlet of the heat exchanger, and then flow into the body wrap again, or the liquid in the body wrap can flow back to the reservoir through the liquid outlet of the body wrap and the liquid outlet of the reservoir.
