As shown in fig. 1 to 3, the present invention provides a door body 100, the door body 100 is suitable for a refrigerator (not shown), the door body 100 includes a first door body 10, a storage frame 30 and a heat conducting member, the first door body 10 includes an opening 14; the storage frame 30 is assembled at the rear side of the first door 10, and comprises a storage space 31, and the front end of the storage space 31 is communicated with the opening 14; the heat conducting piece is arranged on one side of the storage frame body 30; wherein, when the door body 100 is closed at the front side of the cabinet of the refrigerator, the heat conductive member is located in the compartment in the cabinet.
In this embodiment, the heat conducting member is located in the compartment in the case, and heat in the storage space 31 is conducted toward the compartment through the heat conducting member, so that the temperature in the storage space 31 is reduced, and refrigeration of the storage space 31 is achieved. The storage space 31 is completely independent relative to the compartment in the box body and is not mutually communicated, so that the problem of odor tainting caused by air cooling and refrigeration of the existing door storage space can be solved. And, the heat conducting member cools the storage space 31 in a manner similar to "direct cooling" cooling.
The "the heat conductive member is disposed on one side of the storage frame 30" means that a portion of the storage frame 30 is a heat conductive member, for example, the rear sidewall 303 (as shown in fig. 5) of the storage frame 30 is a heat conductive member made of a metal material, including but not limited to an aluminum alloy plate, a copper plate, an aluminum plate, and the like; alternatively, the heat conductive member is, for example, an aluminum alloy plate, a copper plate, an aluminum plate, or the like made of a metal material, and is bonded to the outside of the storage frame 30 by adhesion, fixation, or the like; alternatively, as shown in fig. 2 and 3, the heat conducting member 40 is, for example, an aluminum alloy plate, a copper plate, or an aluminum plate made of a metal material, and forms an outer frame together with other structures, and the outer frame is covered on the outer side of the storage frame 30 (as shown in fig. 1 to 3).
As shown in fig. 1 to 5, the outer frame body is covered on the rear side of the first door body 10, and the outer frame body is covered on the outer side of the storage frame body 30, so that an air flow channel 60 is formed between the outer frame body and the storage frame body 30, one end of the air flow channel 60 is communicated with the air inlet of the storage frame body 30, and the other end of the air flow channel 60 is communicated with the air return opening 32 of the storage frame body 30, so that the air flow channel 60 and the storage space 31 are mutually communicated.
In this embodiment, the temperature in the compartment of the case is low, that is, the temperature of the heat conductive member 40 toward the compartment is lower than the temperature toward the storage frame 30. Because of the temperature difference between the two sides of the heat conducting member 40, the air in the air flow channel 60 exchanges heat on the surface of the heat conducting member 40, the heat diffuses toward the compartments, the cold provided by the compartments enters the air flow channel 60 through the heat conducting member 40, and the air in the air flow channel 60 is cooled; the cooled air enters the storage space 31 from an air inlet (not shown) of the storage frame 30, exchanges heat with the air in the storage space 31, then enters the air flow channel 60 from the air return opening 32 of the storage frame 30, and continuously exchanges heat on the surface of the heat conducting member 40 to be cooled, thereby realizing the refrigeration cycle of the storage space 31.

As shown in fig. 2 and 3, the outer frame further includes an upper cover 41 and a lower cover 42 disposed opposite to each other, and the upper cover 41 and the lower cover 42 are combined at opposite ends of a frame, i.e., the heat conductive member 40.

In addition, it was verified through experiments that the heat conductive member 40 shown in fig. 2 and 3 was used to have a similar effect of lowering the storage space 31 as compared with the integrated outer frame made of an aluminum alloy material.
As shown in fig. 2 to 4, 7 and 8, the heat conducting member 40 includes a rear wall 401 and two opposite side walls 402, 403, the two opposite side walls 402 being located on two opposite sides of the rear wall 401 and protruding toward the front side of the first door body 10, and the two opposite side walls 402, 402 being respectively formed with flanges 404, the flanges 404 being parallel to the rear wall 401 and protruding toward the outside of the storage frame body 30.

Specifically, the present invention relates to a method for manufacturing a semiconductor device. The air in the air flow channel 60 exchanges heat on the surface of the heat conducting member 40, the heat diffuses toward the compartments, the cold provided by the compartments enters the air flow channel 60 through the heat conducting member 40, and the air in the air flow channel 60 is cooled; the fan rotates, and the cooled air in the air flow channel 60 is blown into the storage space 31 from the air inlet on the top plate 301; the air flows back into the airflow path 60 through the return air inlet 32 in the base plate 302. That is, the air flows through the storage space 31 from top to bottom, and flows through the air flow channel 60 from top to bottom. The cooled air introduced from the air flow channel 60 circulates from top to bottom, so as to quickly cool the storage space 31.
