[0005] The purpose of the present utility model is to provide an internal air-cooling structure for a new energy vehicle-mounted refrigerator. By integrating the evaporator and the fan on the same air duct component to form an air-cooling module, it is convenient to install the entire air-cooling module on the whole vehicle-mounted refrigerator, realizing modular assembly. In addition, only one fan sucks the air in the inner container, passes it through the evaporator, and then transports it back into the inner container. The structure is simple, the air-cooling structure is simplified, and the cost is reduced. The air-cooling module is installed on the outer side of the inner container without occupying the internal space of the inner container.

[0006] The purpose of the present utility model is realized as follows:

[0007] An internal air-cooling structure for a new energy vehicle-mounted refrigerator, including an evaporator and a fan arranged on the outer side of an inner container.

[0008] The evaporator and the fan are integrally arranged on the same air duct component.

[0009] The air duct component, the evaporator and the fan form an air-cooling structure built in the main body of the vehicle-mounted refrigerator.

[0010] The air inlet of the fan is communicated with the inner container, the air outlet of the fan is correspondingly arranged with the evaporator, and the air in the inner container is sucked by the fan, exchanges heat through the evaporator to form cold air, and returns along the air duct component to be transported back into the inner container, forming an air-cooling structure for internal circulation refrigeration in the inner container.

[0011] The main body of the vehicle-mounted refrigerator includes a box body covering the inner container. An installation cavity for installing the air duct component is formed between the inner side of the box body and the outer side of the inner container. One side of the air duct component is installed on the outer side of the inner container, and the other side of the air duct component abuts against the inner side of the box body.

[0012] The evaporator and the fan are encapsulated in the air duct component through the inner side of the box body, so as to form a relatively airtight cold air conveying air duct in the air duct component, effectively preventing the gas entering the air duct component from leaking.

[0013] The cold air conveying air duct is communicated with the inner cavity of the inner container.

[0014] The air duct component is provided with an inner container air inlet and an inner container air outlet.

[0015] The air outlet of the fan and the inner cavity of the inner container are both communicated with the inner container air inlet.

[0016] The air inlet of the fan and the inner cavity of the inner container are both communicated with the inner container air outlet.

[0017] The height position of the inner tank air inlet on the air duct member is higher than the height position of the fan on the air duct member, and the evaporator is arranged between the inner tank air inlet and the fan, so that the cold air passes through the fan, the evaporator and the inner tank air inlet from bottom to top and enters the inner tank. Cold air is denser than hot air. This is because the higher the temperature, the more active the molecular activity, the larger the gap between molecules, the larger the volume, and the lower the density, that is, the density decreases; conversely, as the temperature decreases, the molecular activity weakens, the gap between molecules becomes smaller, the volume becomes smaller, and the density increases, that is, the density increases. Therefore, the cold air entering the inner tank sinks, and the cold air sucked into the inner tank by the fan is cooled by heat exchange in the evaporator and then returned to the inner tank through the upper inner tank air inlet, thereby improving the refrigeration effect of the inner tank, so that the refrigerator inner tank can reach the set refrigeration temperature in a shorter time.

[0018] The air duct member is provided with a fence for surrounding the evaporator, the fan and the air inlet of the inner tank, one side of the fence abuts against the inner side of the vehicle refrigerator body, and a cold air delivery duct connecting the air inlet of the inner tank and the inner tank is formed between the fence and the inner side of the vehicle refrigerator body. The fence surrounds the evaporator, the fan and the air inlet of the inner tank, preventing the cold air entering the air inlet of the inner tank from passing through the fan and the evaporator to leak outward to the outside of the fence, thereby ensuring the circulation refrigeration effect in the inner tank.

[0019] A circulating fan is provided inside the inner tank, and the circulating fan drives the cold air entering the inner tank to circulate in the inner tank. A circulating fan is provided inside the inner tank, and the cold air in the inner tank circulates in the inner tank through the circulating fan, thereby avoiding uneven distribution of refrigeration temperature in the inner tank.

[0020] The circulation fan inside the inner tank is arranged corresponding to the air inlet of the inner tank.

[0021] A VIP plate is provided on the outer peripheral side of the inner liner, and the VIP plate covers the outer peripheral side of the inner liner to form a heat preservation layer on the outer side of the inner liner.

[0022] The vehicle refrigerator body comprises a box body, which covers an inner tank and a VIP plate on the outer peripheral side of the inner tank, and a foaming layer is provided between the inner side of the box body and the VIP plate.

[0023] The combination of VIP board and foam layer enables the refrigerator to achieve maximum insulation effect within a limited space and can effectively reduce the loss of internal cold air.

[0024] The vehicle refrigerator body is provided with a machine compartment for installing a condenser and a compressor, and the compressor, the condenser and the evaporator are connected to each other through pipelines to form a refrigeration device of the vehicle refrigerator body.

[0025] The beneficial effects of the utility model are as follows:

[0026] The evaporator and the fan are integrally arranged on the same air duct component to form an air-cooling module, which is convenient for installing the whole air-cooling module on the vehicle-mounted refrigerator body to achieve modular assembly. In addition, only one fan sucks the air in the inner container, passes it through the evaporator and then transports it into the inner container. The structure is simple, the air-cooling structure is simplified, and the cost is reduced. The air-cooling module is installed on the outer side of the inner container without occupying the internal space of the inner container. Description of the Drawings
