The form of the external circulation fan 4 blowing air outward is not easy to form internal dust accumulation, and the exhaust air can be directly discharged to the matching gap of the outer side of the automobile auxiliary instrument panel frame, and the gap is used to absorb cold / hot air, without the need to design an additional air duct.

[0027] The heating and cooling box body 1 is integrated with the frame of the automobile's auxiliary instrument panel, including an outer panel 11 and an inner liner 12. The outer panel 11 cooperates with the frame of the automobile's auxiliary instrument panel to fix the heating and cooling box body 1 with the frame of the automobile's auxiliary instrument panel to form an integral auxiliary instrument panel; the inner liner 12 is nested in the outer panel 11, forming a cavity for accommodating items, and the gap between the outer panel 11 and the inner liner 12 is filled with an inner liner insulation layer 13. The fan outer panel 5 is fixed to the outer panel 11 by screws. The armrest cover 14 is rotatably connected to the outer panel 11 by a pin shaft.

[0030] The air cooling system implemented by the internal circulation module is adopted inside the cold and warm box to achieve the temperature balance inside the cold and warm box. The internal circulation module is arranged on the inner side of the inner tank 12, and its position matches the position of the semiconductor cold and hot module 3. The internal circulation module includes an inner baffle 15, an inner circulation fan 16 and a heat conductive block 17. An inner circulation air duct is formed between the inner baffle 15 and the inner wall of the inner tank 12. The heat conductive block 17 is arranged in the middle of the inner circulation air duct and fits the inner wall of the inner tank 12. The position of the heat conductive block 17 corresponds to the position of the semiconductor cold and hot module 3 to receive the heat transfer of the semiconductor cold and hot module; the internal circulation fan 16 is arranged in the inner circulation air duct to promote the air circulation in the inner circulation air duct. In this embodiment, the inner circulation air duct is designed vertically, with air inlet at the bottom and air outlet at the top.

A semiconductor cold and hot module 3 and a corresponding heat dissipation module 31 and an external circulation module are arranged on one side of the cold and warm box body 1 facing the auxiliary instrument panel frame 2 in the length direction. The external circulation fan of the external circulation module directly discharges the exhaust air to the auxiliary instrument panel frame 2 of the automobile, and absorbs the exhaust air by using the matching gap of the auxiliary instrument panel itself. There is no need to design an additional air inlet and outlet channel, which does not affect the integration and aesthetics of the auxiliary instrument panel. The cold and warm box body 1 and the outer side (both sides in the width direction) of the auxiliary instrument panel frame 2 of the automobile are connected with side guard plates, and the side guard plates include a left guard plate 6 and a right guard plate 7. The outer side of the side guard plate faces the interior of the automobile and is smooth. The inner side has a buckle that is compatible with the cold and warm box body 1 and the auxiliary instrument panel frame 2 of the automobile. After being connected, the cold and warm box body 1 and the auxiliary instrument panel frame 2 of the automobile form the overall structure of the auxiliary instrument panel. Ventilation holes are provided on the side guard plates to realize air intake and exhaust, meet the gas circulation requirements, and facilitate the cold and hot gases generated by the semiconductor cold and hot module to be dispersed to ensure reliability.

[0032] A controller is also fixedly arranged on the cooling and heating box assembly body 1, and the controller is used to control the operation of the semiconductor cooling and heating module according to the received instructions, and adjust the working state of the internal circulation and external circulation fans. The controller can be fixed to the bottom of the outer plate 11 or other convenient installation position by screws.

The overall body of the cooling and heating box is integrated with the frame of the car sub-instrument into an integrated assembly structure, and side guard plates are provided on both sides to form an overall sub-instrument structure. The overall structure has a high degree of integration and occupies a small space. Accordingly, the cooling and heating box can be easily enlarged to meet large-capacity storage needs. The cooling and heating box adopts an air-cooling design to achieve temperature balance inside the cooling and heating box. The external circulation fan takes away the cold / heat, and absorbs the cold / hot air through the matching gap of the sub-instrument itself to achieve heat exchange. There is no need to specially design the inlet and outlet ducts, which not only reduces the cost, but also does not affect the overall appearance, making the interior more refined and coordinated.
