[0019] The cooling backpack 2 is divided into an upper cavity 12 and a lower cavity 13 by a supporting isolation plate 11. The semiconductor cooler 7, the fan 8 and the supporting isolation frame 6 are all located in the lower cavity 13. The supporting isolation frame 6 and the supporting isolation plate 11 are tightly connected by bolts to ensure the stable support of the internal space of the cooling backpack 2.

[0020] The back cushioning layer 10 consists of a soft fabric cover and highly elastic memory foam. The memory foam is placed on the fabric cover, which is sewn onto the inner wall of the cooling backpack 2 with fine stitching, providing comfortable back support. The cushioned connecting tube 9 is a soft connecting hose that passes through the back cushioning layer 10 and connects to the cooling protective suit 1, ensuring smooth airflow.

[0021] The support isolation frame 6 adopts a directional frame design. The inner filter screen 5 is firmly installed on the support isolation frame 6 with bolts. The surfaces of the support isolation frame 6 and the support isolation plate 11 are covered with cloth covers, and the cloth covers, support isolation frame 6 and support isolation plate 11 are connected to the refrigeration backpack 2 by needle and thread, so that the overall structure is stable.

[0022] Two fans 8 are symmetrically distributed on both sides of the semiconductor cooler 7, which is connected to the power supply and control unit 14 via wires to ensure the normal operation of the cooling system. The cooling backpack 2 is made of waterproof material and has a water storage bag at the bottom inside for emergencies.

[0023] The upper and lower ends of the front flap 3 are designed as air inlets, while the buffered connecting pipe 9 is an air outlet.
