The secondary refrigerant absorbs heat through the hose inner container 2, then converges to the main liquid return pipe 5 from the corresponding four liquid return pipes 22, and enters the soft box for cooling.

As shown in fig. 2, two closed flexible molds (i.e., a first flexible mold 3 and a second flexible mold 4) are connected in series in the coolant circuit, and the first flexible mold 3 and the second flexible mold 4 are connected in series. After the two soft boxes are respectively provided with the hole 8 with the shape and the area equal to those of the semiconductor 7, the graphene sheet 6 with extremely high plane heat conductivity coefficient is respectively attached to the two soft boxes from the inside, and the graphene sheet 6 exposed out of the hole 8 is directly attached to the cold end of the semiconductor 7, so that the heat conduction area of the cold end is increased. The soft type box is connected with the cold end of the semiconductor 7 through the graphene sheet 6, and cold energy generated by the cold end of the semiconductor 7 is introduced into secondary refrigerant.

The two soft type boxes are horizontally laid, are connected in series through the hose and keep a certain distance, and sufficient horizontal space is provided for the air-cooled heat pipe radiating device. The joint of the main liquid return pipe 5 of the secondary refrigerant and the first-level flexible mold box 3 is positioned at the upper part of the first-level flexible mold box 3, the hose at the joint of the first-level flexible mold box 3 and the second-level flexible mold box 4 is positioned in the middle of the two flexible mold boxes, and the joint of the main liquid supply pipe 9 of the secondary refrigerant and the second-level flexible mold box 4 is positioned at the lower part of the second-level flexible mold box 4.
