Technical Field

[0001] The utility model relates to the technical field of cold chain transportation, and specifically discloses an energy-saving and heat-insulating refrigerated truck. Background Art

[0002] The existing refrigeration unit installed in the refrigerated truck compartment generates cold air that is directly delivered to the interior of the compartment. Since the air outlet of the refrigeration unit is located at a high position, items in the compartment far away from the air outlet cannot be fully exposed to the cold air for cooling. Therefore, the refrigeration unit needs to run for a long time to meet the cooling requirements for items far away from the air outlet, resulting in a low cooling rate for the items.

[0008] Beneficial effects:

[0009] 1. The energy-saving and heat-insulating refrigerated truck installs air outlet ducts with equal spacing on the inner side of the car, so that the cold air generated by the refrigeration unit can be evenly transported to the inside of the car through the exhaust holes on the air outlet ducts, thereby ensuring that the items in the car can be fully exposed to the cold air for rapid cooling. The servo motor can drive the baffle to rotate while adjusting the air intake of each first connecting pipe, thereby controlling the air outlet of each group of air outlet ducts.

DETAILED DESCRIPTION

[0019] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0020] The accompanying drawings in the embodiments of the present invention: different types of section lines in the drawings are not marked according to national standards, nor do they impose any requirements on the materials of the components. Instead, they are used to distinguish the cross-sectional views of the components in the drawings.

[0021] See also Figure 1-6 , an energy-saving and heat-insulating refrigerated truck, comprising a compartment 1 fixedly installed on the refrigerated truck, a refrigeration unit 2 fixedly mounted on the inner side of the front of the compartment 1, and a feed port 3 arranged on one side of the compartment 1. An air supply pipe 4 connected to the refrigeration unit 2 is fixedly installed on the top of the inner side of the compartment 1 through a fixing component. A first connecting pipe 5 distributed at equal intervals is arranged on the outer side of the air supply pipe 4. Second connecting pipes 6 are arranged on both sides of the first connecting pipe 5. The second connecting pipe 6 is connected to an air outlet pipe 8 fixedly installed on both sides of the inner side of the compartment 1 through a fixing component through a connecting sleeve 7. The two air outlet pipes 8 are symmetrically distributed on both sides of the first connecting pipe 5 in a group. An air volume regulating mechanism 9 is installed on the inner side of the first connecting pipe 5. The air volume regulating mechanism 9 is provided with a control unit in the refrigerated truck, and the control unit can separately control each air volume regulating mechanism 9, so as to control and adjust the opening and closing angle of each baffle 96 separately, thereby realizing the precise delivery of cold air.

[0022] The air volume regulating mechanism 9 comprises a first fixed sleeve 91 and a second fixed sleeve 92 arranged on the outside of the first connecting tube 5 and a servo motor 93 fixedly installed on the outside of the second connecting tube 6. The interiors of the first fixed sleeve 91 and the second fixed sleeve 92 are rotatably connected to a rotating shaft 95 movably sleeved inside the first connecting tube 5 through a bearing 94. A baffle 96 is sleeved inside the rotating shaft 95. The outer side of the bottom end of the rotating shaft 95 is fixedly sleeved with the output shaft of the servo motor 93 through a sleeve 97. The servo motor 93 drives the baffle 96 to rotate around the axial direction of the rotating shaft 95 while adjusting the opening and closing angle of the baffle 96, so as to control the air intake of each first connecting tube 5 and ensure that the cold air can be accurately delivered to the compartment. The temperature is relatively high in the area, so as to quickly cool down the items in the car and reduce the driving time of the refrigeration unit 2. The outer thread of the first fixed sleeve 91 is sleeved with a first sealing cover 98, and the outer thread of the second fixed sleeve 92 is sleeved with a second sealing cover 99 movably sleeved on the outer side of the bottom end of the rotating shaft 95. The first sealing cover 98 and the second sealing cover 99 can seal the first fixed sleeve 91 and the second fixed sleeve 92 to ensure that the cold air inside the first connecting pipe 5 will not directly leak to the outside of the first connecting pipe 5. The surface of the baffle 96 is provided with a boss 910 located on one side of the rotating shaft 95. The baffle 96 can be positioned by the boss 910, so that after the baffle 96 is sleeved on the inner side of the rotating shaft 95, it is convenient to install the second bolt 13.

[0023] Among them, the inside of the air outlet duct 8 is provided with exhaust holes 10 distributed at equal intervals, and the fixed components on the air outlet duct 8 are staggered with the exhaust holes 10, so that the cold air inside the air outlet duct 8 can be transported to various areas inside the compartment 1 through the exhaust holes 10, thereby ensuring that the cold air can fully contact the objects.

[0024] Among them, a sealing plate 12 is fixedly installed inside the bottom of the first connecting tube 5 by a first bolt 11. The first bolt 11 and the sealing plate 12 can seal the opening at the bottom of the first connecting tube 5, and the baffle 96 can be disassembled and assembled from the opening by removing the sealing plate 12.

[0025] Among them, the internal thread of the rotating shaft 95 is sleeved with a second bolt 13 located on the inner side of the top of the baffle 96. The baffle 96 can be limited and fixed by the second bolt 13, and the limitation of the baffle 96 can be released by removing the second bolt 13, so that the baffle 96 can be removed from the opening at the bottom of the first connecting pipe 5.

[0026] When the refrigerated truck is working, the cold air generated is transported to the inside of the air supply duct 4 through the refrigeration unit 2, the cold air inside the air supply duct 4 is transported to the inside of the air outlet duct 8 through the first connecting pipe 5, and the cold air inside the air outlet duct 8 is transported to various areas inside the compartment 1 through the exhaust holes 10, and the objects are cooled by the contact between the cold air and the objects. The servo motor 93 is controlled to start through the control unit on the refrigerated truck, and the baffle 96 is driven by the servo motor 93 to rotate around the axial direction of the rotating shaft 95 while adjusting the opening and closing angle of the baffle 96, thereby controlling and adjusting the air outlet volume of each group of air outlet ducts 8, and accurately transporting the cold air to the required areas.
