1. A portable system for cold therapy with optional heat and compression therapy, applied to a first 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, and the fan are placed outside the reservoir; the heat exchanger is placed inside or underneath the reservoir, and is in direct or indirect contact with liquid in the reservoir to cool the liquid;
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, enabling refrigerant in the compressor to pass through the condenser first and then through the heat exchanger to achieve a cooling effect;
the fan has a working surface facing the condenser; and
the reservoir comprises a first liquid inlet of the reservoir and a first liquid outlet of the reservoir; wherein the liquid in the reservoir flows into the first body wrap through the first liquid outlet of the reservoir, and liquid in the first body wrap flows into the reservoir through the first liquid inlet of the reservoir;
the heat exchanger comprises a first cooling plate placed inside the reservoir; wherein the first cooling plate comprises a first air inlet of the first cooling plate, a first air outlet of the first cooling plate, a second liquid inlet of the first cooling plate, and a second liquid outlet of the first cooling plate; and wherein the first air outlet of the first cooling plate is connected to the first tube, and the first air inlet of the first cooling plate is connected to the second tube; and the second liquid inlet of the first cooling plate is connected to the first liquid inlet of the reservoir through a fourth tube.
