[0028] As shown in Figures 1 to 8 , the cooling device of the vehicle-mounted refrigerator of the utility model includes the refrigerator liner 1, the solid cold storage block 2, the semiconductor refrigerator 3, the radiator 5, the fixed column 6 and the screw 7, the fixed column 6 sequentially passes through the radiator 5, the semiconductor refrigerator 3, the solid cold storage block 2 and the refrigerator liner 1 and is screwed by the screw 7, so as to lock and fix the radiator 5, the semiconductor refrigerator 3, the solid cold storage block 2 and the refrigerator liner 1 by cooperation of the fixed column 6 and the screw 7. By this arrangement, the refrigerator liner 1, the solid cold storage block 2, the semiconductor refrigerator 3 and the radiator 5 are fixed together in series by cooperation of the fixed column 6 and the screw 7, which is convenient to assemble, has low labor cost and is stable after assembly (in the traditional technology, the refrigerator liner and the radiator are not coaxially connected by the screw, but are connected to the plastic pipe of the solid cold storage block respectively, which is not stable after assembly and is prone to shaking after long-term use), and is convenient to disassemble and maintain. In practical application, the semiconductor refrigerator 3 is provided with double wire columns 32 for assembly with wires.

In this way, the structure is simple and convenient to assemble.

[0030] Further, the bottom of the inner liner 1 of the refrigerator is provided with a hole one 11 matched in size with the connecting end one 62, the solid cold storage block 2 is provided with a hole two 21 matched in size with the connecting end one 62, the semiconductor refrigerator 3 is provided with a hole three 31 matched in size with the connecting end one 62, and the heat sink 5 is provided with a hole four 51 matched in size with the connecting end one 62, and when the connecting end one 62 of the upper end of the fixed column 6 is sequentially threaded through the hole four 51 of the heat sink 5, the hole three 31 of the semiconductor refrigerator 3, the hole two 21 of the solid cold storage block 2 and the hole one 11 of the inner liner 1 of the refrigerator, the end of the connecting end one 62 is flush with the upper surface of the bottom of the inner liner 1 of the refrigerator.

In this way, after assembly, the heat insulation cotton is arranged around the outer periphery of the semiconductor refrigerator 3, which can reduce the loss of cold energy, so that the cold energy generated by the semiconductor refrigerator 3 acts on the solid cold storage block 2, and then is transmitted to the inner liner 1 of the refrigerator, and the refrigeration effect is better.

[0034] Further, the bottom of the inner liner 1 of the refrigerator is formed with a limiting installation groove 12 matched in size with the solid cold storage block 2, and the hole one 11 is located in the limiting installation groove 12.
