A refrigeration device, characterized in that: It includes: A box body, one side of which is open; An inner liner, the inner liner is disposed in the box body, the inner liner has an opening and faces the same direction as the opening of the box body; An air duct plate, the air duct plate is arranged in the inner liner, one side of the air duct plate and the inner liner form an air supply duct, and the other side of the air duct plate and the inner liner form a storage chamber; Wind shields, the wind shields are arranged on both sides of the air duct plate in the width direction, and the wind shields are inclined toward the air supply duct; A sealing member, the sealing member being arranged on a side of the air duct plate facing the air supply duct; A first mounting hole, the first mounting hole being opened on the air duct plate; A second mounting hole, the second mounting hole being opened in the inner container; A fastener passes through the first mounting hole and the second mounting hole so that the side of the wind shield plate close to the inner tank abuts against the inner wall of the inner tank to form a first seal between the storage chamber and the air supply duct, and at the same time, the two sides of the seal respectively abut against the side wall of the air duct plate and the inner wall of the inner tank to form a second seal between the storage chamber and the air supply duct.

2. The refrigeration equipment according to claim 1, characterized in that: The wind shield plate is a flange formed by extending from both sides of the air duct plate in the width direction toward a side away from the storage chamber, and the flange and the sealing member are spaced apart along the width direction of the air duct plate.

3. A refrigeration device, characterized in that: It includes: A box body, wherein the box body is hollow; An inner liner, the inner liner is arranged in the box body, the inner liner has a containing cavity, and the inner liner has an opening communicating with the containing cavity; An air duct plate, the air duct plate is arranged in the accommodating cavity, one side of the air duct plate and the inner liner form an air supply duct, and the other side of the air duct plate and the inner liner form a storage chamber; A sealing member, wherein the sealing member is multiple, each of the sealing members is arranged on a side of the air duct plate facing the air supply duct, and each of the sealing members is located on both sides of the air duct plate in the width direction; A first mounting hole, the first mounting hole being opened on the air duct plate; A second mounting hole, the second mounting hole being opened in the inner container; A fastener passes through the first mounting hole and the second mounting hole so that two sides of each seal are respectively in contact with the side wall of the air duct plate and the inner wall of the inner tank to form a multi-channel seal between the storage chamber and the air supply duct.

4. The refrigeration device according to any one of claims 1 to 3, characterized in that: The inner container has a step portion, the step portion is arranged between the inner wall of the air supply duct and the inner wall of the storage chamber, and the step portion abuts against the sealing member on a side facing the storage chamber.

5. The refrigeration device according to claim 4, characterized in that: The side of the step portion close to the air supply duct abuts against the sealing member, so that the sealing member seals the gap between the step portion and the air duct plate.

6. The refrigeration device according to claim 5, characterized in that: The air duct plate has bending parts on both sides in the width direction, and the bending part on one side away from the storage chamber faces the step part, and the bending part on one side away from the storage chamber abuts against the sealing member.

7. The refrigeration device according to claim 6, characterized in that: The air duct plate has mounting parts on both sides in the width direction, the length direction of the mounting parts is the same as the length direction of the air duct plate, the mounting parts are connected to the bending parts, and the first mounting holes are opened in the mounting parts.

8. The refrigeration device according to claim 7, characterized in that: The first mounting hole is a countersunk hole recessed toward the air supply duct side, and there are a plurality of the first mounting holes, which are spaced apart along the length direction of the mounting portion.

9. The refrigeration device according to any one of claims 1 to 3, characterized in that: The sealing member is a sealing foam, and the sealing foam is used to seal the gap between the storage chamber and the air supply duct.

10. The refrigeration device according to any one of claims 1 to 3, characterized in that: The length direction of the sealing member is the same as the length direction of the air duct plate, and the length of the sealing member is not less than the length of the air duct plate.
