Multiple sets of grooves are provided on the other side of the guide plate, with the length of each groove equal to the width of the guide plate. This device solves the problem that existing refrigerated containers' cooling fans cannot deliver air to multiple areas.

Description

Technical Field

[0001] This utility model belongs to the technical field of refrigerated transport equipment, specifically relating to a refrigerated container. Background Technology

[0002] A refrigerated container is a special type of container equipped with refrigeration equipment to maintain a constant low temperature during transportation and storage. It is the core equipment of modern cold chain logistics, ensuring that perishable goods (such as food and medicine) are kept in a suitable temperature environment from the place of origin to the place of consumption. The uniformity of cold air circulation in its refrigeration system directly determines the preservation quality of the goods.

[0003] However, existing refrigerated containers typically have a cooling fan installed at the end furthest from the door, along with a deflector to guide the airflow. But traditional deflectors are mostly flat or single-arc structures, with limited functionality. They can only guide airflow in one direction and cannot meet the needs of uniform airflow to multiple areas, including the front, middle, and sides of the container. This can easily lead to significant temperature differences in different parts of the container, especially for temperature-sensitive goods such as fruits, vegetables, and pharmaceuticals transported over long distances. This can easily cause localized spoilage. Therefore, this phenomenon has become a problem that urgently needs to be solved by those in the field. Utility Model Content

[0004] The purpose of this invention is to provide a refrigerated container to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a refrigerated container, including a container body, a container door, and a cooling fan. The container door is hinged to one end of the container body, and the cooling fan is fixedly connected to the inside of the container body away from the container door. It is used to drive the circulation of cold air to achieve refrigeration and cooling. A guide plate is provided on the side of the cooling fan near the container door. A protrusion is provided on one side of the guide plate. The protrusion is herringbone shaped and multiple protrusions are arranged along the width direction of the guide plate. The protrusion can guide the airflow to diffuse in the length direction of the guide plate, thereby leading the airflow to both sides of the container body to achieve uniform cooling.

[0006] The present invention further explains that baffles are fixed at both ends of the air guide plate, and the baffles are set on the same side of the protrusion. The baffles can further guide the airflow of the protrusion to the lower sides of the box.

[0007] The present invention further explains that multiple sets of grooves are provided on the other side of the air guide plate. The length of each set of grooves is equal to the width of the air guide plate. The grooves are arc-shaped, which can further guide the airflow to diffuse along the trajectory. At the same time, the grooves can also disperse the stress generated by the airflow impact and improve the deformation resistance of the air guide plate.

[0008] The present invention further describes that both sides of the air cooler are fixedly connected to slide rails, and sliders are slidably connected to the slide rails. A bracket is fixedly connected to the slider, and a rotating shaft is rotatably connected to one end of the bracket near the air guide plate. The rotating shaft is fixedly connected to the air guide plate.

[0009] This utility model further explains that a micro motor is keyed to the end of the rotating shaft away from the air guide plate, and the rotation of the air guide plate angle is achieved by driving the micro motor.

[0010] This utility model further illustrates that the micro motor is fixedly connected to the bracket.

[0011] Compared with existing technologies, the beneficial effects achieved by this utility model are as follows: In this utility model, the air guide plate has a protrusion on one side and a groove on the other. When the protruding side of the air guide plate faces the evaporative cooler, the herringbone-shaped protrusion can quickly divert the airflow output by the cooler and precisely guide it to the two sides of the housing. Combined with the baffle on the same side as the protrusion, the airflow can further diffuse downwards, eliminating temperature dead zones on both sides of the bottom of the housing. When the arc-shaped groove on the other side of the air guide plate faces the cooler, the airflow diffuses smoothly along the arc-shaped trajectory of the groove, reaching the front and middle areas of the housing. Ultimately, it can achieve all-round airflow coverage to the front, middle, and sides of the housing. Attached Figure Description

[0013] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0014] Please see Figure 1-6 This utility model provides a technical solution: a refrigerated container, including a container body 1, a container door 4, and a cooling fan 2. The container door 4 is hinged to one end of the container body 1. The cooling fan 2 is fixedly connected to the inside of the container body 1 away from the container door 4 and is used to drive the circulation of cold air to achieve cooling. A guide plate 3 is provided on the side of the cooling fan 2 near the container door 4. A protrusion 5 is provided on one side of the guide plate 3. The protrusion 5 is herringbone shaped and multiple protrusions are provided along the width direction of the guide plate 3. The protrusion 5 can guide the airflow to diffuse in the length direction of the guide plate 3, thereby leading the airflow to both sides of the container body 1 to achieve uniform cooling.

[0015] The air guide plate 3 has baffles 7 fixed at both ends. The baffles 7 are located on the same side as the protrusion 5. The baffles 7 can further guide the airflow of the protrusion 5 to the lower sides of the box 1.

[0016] On the other side of the air guide plate 3, there are multiple sets of grooves 6. The length of each set of grooves 6 is equal to the width of the air guide plate 3. The grooves 6 are arc-shaped, which can further guide the airflow to diffuse along the trajectory. At the same time, the grooves 6 can also disperse the stress generated by the airflow impact and improve the deformation resistance of the air guide plate 3.

[0017] The air cooler 2 has slide rails 8 fixedly connected to both sides, sliders 9 are slidably connected to the slide rails 8, and brackets 10 are fixedly connected to the sliders 9. The end of the bracket 10 near the air guide plate 3 is rotatably connected to the rotating shaft 11, and the rotating shaft 11 is fixedly connected to the air guide plate 3.

[0018] The end of the rotating shaft 11 away from the air guide plate 3 is keyed to a micro motor 12, and the rotation angle of the air guide plate 3 is achieved by driving the micro motor 12.

[0019] The micro motor 12 is fixedly connected to the bracket 10.

[0020] Working principle: When airflow needs to be guided to the front and middle of the housing 1, the drive slider 9 operates on the slide rail 8, which in turn drives the bracket 10 to operate on the slide rail 8, thereby moving the air guide plate 3 to the upper middle part of the air cooler 2. The micro motor 12 is then driven to operate, adjusting the angle of the air guide plate 3. At this time, the side of the air guide plate 3 with the groove 6 faces the air cooler 2. The groove 6 can further guide the airflow to diffuse along the trajectory and prevent airflow turbulence. When airflow needs to be guided to the sides of the housing 1, the drive micro motor 12 is driven to operate, so that the side of the air guide plate 3 with the protrusion 5 faces the air cooler 2. The herringbone shape of the protrusion 5 can guide the airflow to the sides of the housing 1. At the same time, the baffle 7 further guides the airflow to the bottom of the housing 1. Finally, it can achieve all-round coverage of the front, middle and sides of the housing 1, ensuring the temperature consistency of the housing 1.
