Beschreibung
Zusammenfassung:	The invention discloses a soil test box bottom closed-loop refrigerating system which comprises a soil test box and a refrigerator used for cooling the soil test box, the interior of a bottom plate interlayer of the soil test box is divided into at least two independent areas, and each independent area is internally provided with a snakelike groove; and one end of each snakelike groove is connected with a liquid outlet of the refrigerator, and the other end of each snakelike groove is connected with a liquid inlet of the refrigerator. According to the invention, the S-shaped grooves with at least two independent areas are formed in the interlayer of the bottom plate of the soil test box, the liquid outlets and the liquid inlets of the S-shaped grooves are communicated with the refrigerator, and the flowing time of cooling liquid in the S-shaped grooves is prolonged through the bent structures of the S-shaped grooves; and the bottom plate of the large soil test box can fully cool the soil body in the soil test
