[0012] like Figures 1 to 5 As shown, a spare tire type vehicle refrigerator includes a semicircular vehicle refrigerator 10, the curvature center of the vehicle refrigerator 10 coincides with the curvature center of the spare tire cavity A, and a turntable 20 is arranged at the bottom of the vehicle refrigerator 10, and the rotation center of the turntable 20 coincides with the center of the spare tire cavity A. The vehicle refrigerator 10 is arranged using the original space of the spare tire cavity A, and the bottom of the vehicle refrigerator 10 is assembled with a turntable 20 to realize the rotation function of the vehicle refrigerator 10. When the vehicle refrigerator 10 needs to be opened to take out items, the control console gives a signal, and the vehicle refrigerator 10 is rotated to the back door, which is convenient for opening the vehicle refrigerator 10. After the operation is completed, the door cover of the vehicle refrigerator 10 is closed, and the control console receives a signal that the door has been closed, and rotates the vehicle refrigerator 10 back to the original position.

[0013] The specific structure is as follows: the vehicle-mounted refrigerator 10 includes a semicircular cylindrical refrigerator body 11, and the upper edge of the straight side of the refrigerator body 11 is hinged to the refrigerator cover 12 through a hinge shaft 111. The axis core of the hinge shaft 111 is arranged in the horizontal direction and is consistent with the length direction of the straight side of the refrigerator body 11. The arc edge of the refrigerator cover 12 is locked with the arc edge of the refrigerator body 11 through a push-type lock 15.

[0014] Furthermore, the push-type lock 15 is arranged in the middle position of the arc edge of the refrigerator cover 12, and multiple hinge shafts 111 are evenly and spacedly arranged at the upper edge of the straight side of the refrigerator body 11 to ensure the stability of the refrigerator cover 12 when opening and closing.

[0015] A semiconductor refrigeration unit 30 is arranged on the straight-edge wall of the refrigerator body 11. The semiconductor refrigeration unit 30 includes a heat dissipation pipe 31 fixed on the outer wall of the outer shell of the refrigerator body 11 and a semiconductor refrigeration sheet arranged in a cavity between the outer shell and the inner tank. A cooling plate is fixed to the inner end of the semiconductor refrigeration sheet, and the cooling plate is attached to the outer wall of the inner tank. The cold surface of the semiconductor refrigeration sheet cools and is transferred to the inner tank through the cooling plate, thereby refrigerating the food in the inner tank, and the exchanged heat is promptly and effectively dissipated through the heat dissipation pipe 31, further ensuring the refrigeration effect of the refrigerator.

[0016] In order to improve the heat conduction efficiency, two semiconductor refrigeration units 30 are provided on the straight-side cylinder wall of the refrigerator body 11 and are arranged symmetrically with respect to the midline of the straight-side cylinder wall. The straight-side cylinder wall provides sufficient space for the connection of the semiconductor refrigeration units 30. At the same time, the two semiconductor refrigeration units 30 can meet the use requirements in a short refrigeration time. Moreover, both refrigeration units adopt semiconductor refrigeration, which has the advantages of environmental protection, no pollution, small size, low cost, no vibration and noise during operation, and long service life.

[0017] As a preferred solution of the present invention, fans 32 are provided at the ends of the two heat dissipation pipes 31 adjacent to each other, and the two fans 32 are also arranged symmetrically with respect to the midline of the straight-side tube wall. The advantage of such an arrangement is that the fans 32 can dissipate heat from the heat dissipation pipes 31 while also dissipating heat and cooling the control circuit board 40 located between the two fans 32, thereby extending the service life of the refrigerator.

[0018] A boss 13 is provided at the middle position of the straight-side wall of the refrigerator body 11, on which a control circuit board 40 is provided, and the control circuit board 40 is connected to a power source through a wire 41. The two fans 32 can drive air disturbance around the control circuit board 40, dissipate heat and cool the control circuit board 40, and thus extend the service life of the refrigerator.

[0019] In order to ensure that the rotation center of the refrigerator body 11 coincides with the center of the spare tire cavity A, the radius of the semicircular cylinder of the refrigerator body 11 is smaller than the radius of the spare tire cavity A, so as to reserve space for installing components such as the control circuit board 40. An external flange 14 extends outward from the upper cylinder mouth of the refrigerator body 11. The radius of the semicircular area formed by the arc-edged external flange 14 and the straight-edged external flange 14 is equal to the radius of the spare tire cavity A, which is beautiful and elegant.

[0020] The push-type lock 121 is arranged on the external flange 14 of the arc edge, and the heat dissipation pipe 31, the fan 33 and the control circuit board 40 are arranged below the straight-edge external flange 14. From the user's perspective, that is, the top-down perspective, the heat dissipation pipe 31, the fan 33 and the control circuit board 40 are all hidden, which is beautiful and elegant.

[0021] Since the space of the spare tire cavity A is very large, the vehicle refrigerator 10 does not need to be set so large, and therefore a semicircular tool box 50 is also provided on the turntable 20. The semicircular tool box 50 and the vehicle refrigerator 10 form a circular structure, and the radius of the circular structure coincides with the radius of the spare tire cavity A, thereby maximizing the utilization rate of the spare tire cavity A, and the semicircular tool box 50 is also provided on the turntable 20 for convenient placement of tools.
