The convection cooling box 100 according to some embodiments of the present invention may include a cooling box 110 and a cooling module 120 configured to be detachable from the cooling box 110 . Specifically, the convection cooling box 100 may have a structure in which at least a portion 123 of the cooling module 120 is inserted into an opening 112 provided on one side wall of the cooling box 110 and coupled thereto.

For coupling with the cooling module 120, the cold box 110 may be composed of a box body 111 having an accommodation space and a lid 119 closing the accommodation space.

An opening 112 to which a cooling module 120 for convectively circulating by supplying cold air to the accommodation space is docked may be formed on one side wall of the box body 111 .

In some embodiments, cooling module seating grooves may be formed on the box body 111 and the lid 119 to be coupled to the shape of the cooling module 120, as shown in FIG. 2, and these cooling module seating grooves may be formed. As the cooling module 120 is combined according to the shape, the insulation performance of the inner accommodation space of the cold box 110 can be increased, and the loading efficiency of the plurality of cold boxes 110 inside the logistics warehouse or transportation means 300 can be increased. can be raised

In some embodiments, convection guide irregularities 113 may be formed on the bottom surface of the receiving space of the box body 111 . For smooth circulation of the airflow generated by the cooling module 120, each of the convection guide irregularities 113 extends from the front side of the box where the opening 112 is located to the rear side (first direction, X-axis direction). Each of the convection guide irregularities 113 may be spaced apart from each other in a second direction (ie, Y-axis direction) perpendicular to the first direction on the bottom surface of the accommodation space. As the convection guide irregularities 113 are formed, even if the items accommodated in the accommodation space (S in FIG. 3, for example, fresh food, etc.) fill the floor, a convection circulation passage can be secured below the items. Accordingly, the cooled airflow generated by the cooling module 120 circulates smoothly, so that the cold air inside the accommodation space can be uniformly circulated and maintained.

The cooling module 120 is provided with an internal mounting space and can be detachably docked with the housing 121 forming the outer shape and the cold box, and the convection generating part 123 protruding from the housing 121 so that convection is formed inside the cold box. ) may be included.

That is, the inside of the cold box 110 in a state in which the cooling module 120 is coupled can be insulated from external heat without being in fluid communication with external air.

Although not shown, inside the housing 121, there is a Peltier element that generates cold air toward the inside of the cold box 110, and the cool air generated by the Peltier element toward the inside of the cold box 110 (X-axis direction) is kept cool.

The control unit can precisely control the internal temperature of the cold box by controlling the Peltier element and the cooling fan. It may be performed based on a control signal transmitted from

As shown, the convection generator 123 may have a protruding shape to be detachable from the opening 112 of the cold box. The convection generator 123 may be integrally formed with the housing 121 by injection molding, or may be assembled to the housing 121 as a separate part from the housing 121 .

The convection generating unit 123 includes an inlet 124 for introducing the inner air (internal air) of the cold box 110 into the convection generating unit 123, and at least one for discharging cold air cooled inside the convection generating unit 123. One discharge port 125 may be formed. For simplicity of description, the shapes and positions of the inlet 124 and the outlet 125 are simplified and illustrated, and therefore, the configuration of the present invention is not limited thereto.

The inside of the cold box sucked in through the inlet 124 is converted into cold air by heat exchange with the Peltier element, and the cold air may be discharged back into the cold box through the outlet 125 . That is, air between the cold box and the low-temperature portion of the Peltier element is convected to diffuse cold air into the cold box.

The cooling module may be controlled to operate. That is, in this case, the cooling module does not supply power to the Peltier element and the internal fan, but can operate in a sleep mode in which the reconnection with the cold box is sensed by the docking sensor, thereby increasing the power efficiency of the cooling module and increasing the lifespan of the battery. can try

On the other hand, as described above, in the case where the cooling module is configured to be detachable from the cold box, in a state where the cooling module is removed from the cold box, air or cold air inside the cold box may be discharged to the outside through the opening. Accordingly, a decrease in cooling efficiency due to re-cooling and a decrease in reliability due to temperature change of fresh food may occur.

In order to minimize this problem, the convection cooling box of the present invention is further provided with a link assembly 130 that automatically opens and closes the opening 112 of the cooling box according to the detachment state of the cooling module, or A cover (not shown) capable of manually closing and closing may be further provided.
