Description

Technical Field

[0001] The present invention relates to the technical field of containers, and in particular to a refrigerated container. Background Art

[0002] Refrigerated containers can be used to transport goods that have temperature requirements. Temperature control generally uses mechanical refrigeration to keep the transported goods within a certain temperature range. For general non-breathing goods, only temperature adjustment is generally required, and the air volume requirement is not high. The circulation of cold air can offset the heat leakage of the wall panels. However, for goods with breathing heat (such as fruits, etc.), in addition to providing cold air to offset the cold air of the wall panels, the heat generated by the goods must be replaced by the refrigeration unit. This requires a higher air circulation speed between the goods, especially when the fan is running at a low speed, the fan of the refrigeration machine itself may not be able to meet the ventilation volume requirements between the goods.

[0003] Therefore, it is necessary to provide a refrigerated container to at least partially solve the above problems. Summary of the invention

[0042] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the embodiments of the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the embodiments of the present invention, some technical features well known in the art are not described.

[0043] In order to fully understand the embodiments of the present invention, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art.

[0044] The present invention provides a refrigerated container 100, which mainly includes a box body 110 and a refrigeration unit 120. The refrigeration unit 120 is arranged on the box body 110 and is located at one end of the box body 110. Figures 1 to 8 The refrigerated container 100 of the present invention will be described in detail.

[0045] like Figure 1 and Figure 2 As shown, the box body 110 is roughly constructed as a rectangular parallelepiped structure. The box body 110 includes an end door 113 located at one end and an end plate 119 located above the end door 113, and the refrigeration unit 120 is arranged above the end door 113 and extends through the end plate 119. The box body 110 can also include four top corner pieces 114 and four bottom corner pieces 115. The four top corner pieces 114 are located at the four corner positions of the top of the box body 110, and the four bottom corner pieces 115 are located at the four corner positions of the bottom of the box body 110. The projections of the four top corner pieces 114 and the four bottom corner pieces 115 in the vertical direction overlap. The refrigeration unit 120 is located on the inner side of the rectangular area surrounded by the four top corner pieces 114, so that the overall external dimensions of the box body 110 will not be increased.

[0046] The box body 110 includes an inner top plate 112. The inner top plate 112 is located on the inner side of the top of the box body 110. Figure 3 As shown, an air duct 111 may be provided inside the box 110. The air duct 111 may be provided below the inner top plate 112 along the length direction of the box 110. One end of the air duct 111 is connected to the refrigeration unit 120 and can extend to the other end of the box along the length direction of the box, so as to transport the low-temperature gas discharged from the refrigeration unit 120.

[0047] like Figure 5 As shown, the cross section of the air duct 111 is configured as a semi-ellipse. The air duct 111 may be made of a flexible material and may be fixed to the inner top plate 112 by fasteners (such as rivets). For example, the air duct 111 may be made of canvas.

[0048] like Figure 6 As shown, in a variant embodiment, the cross section of the air duct 111 can be configured as a rectangle. The air duct 111 can be made of a metal material or a non-metal material. In addition, the air duct 111 can be fixed and supported by a plurality of support members 116 between the air duct 111 and the inner top plate 112.

[0049] like Figure 4As shown, the refrigeration unit 120 mainly includes a compression condensing unit 121 and an evaporator 122. The compression condensing unit 121 is arranged on the outside of the box body 110, and the evaporator 122 is connected to the compression condensing unit 121 and arranged on the inside of the box body 110. The compression condensing unit 121 can provide refrigerant for the evaporator 122. Specifically, an opening 117 can be provided on the end plate 119. The evaporator 122 extends from the outside of the box body 110 through the opening 117 and enters the inside of the box body 110.

[0050] In this embodiment, the air outlet of the evaporator 122 is connected to the air duct 111. Specifically, the evaporator 122 may include a fan 123, a heat exchanger 124, a first chamber 125, a second chamber 126, and a third chamber 127. The second chamber 126 connects the compression condensing unit 121 and the fan 123. The first chamber 125 connects the fan 123 and the heat exchanger 124, and the third chamber 127 connects the heat exchanger 124 and the air duct 111. When it is necessary to explain, the "air outlet of the evaporator 122" here specifically refers to the outlet of the third chamber 127. The refrigerant provided by the compression condensing unit 121 can be transported to the heat exchanger 124 through a pipeline, so that the gas flowing through the heat exchanger 124 can exchange heat with the refrigerant.

[0051] The bottom of the second chamber 126 may be provided with a return air port (not shown). More specifically, the return air port may be provided between the fan 123 and the end plate 119. Those skilled in the art will appreciate that the location of the return air port is not limited to the present embodiment, and the return air port may be provided at any suitable location as required. In addition, the first chamber 125, the second chamber 126, and the third chamber 127 may be connected to the outside through a pipeline to achieve a fresh air function.

[0052] The air inlet (not shown) of the fan 123 is connected to the second chamber 126, and the air outlet (not shown) of the fan 123 is connected to the first chamber 125. It should be noted that since the fan 123 is an existing known device, in this embodiment, only the structure of the fan 123 is schematically shown, and the air inlet and air outlet of the fan 123 are not shown.

[0053] When the refrigeration unit 120 is working, under the action of the fan 123 and the heat exchanger 124, a negative pressure area is formed in the second chamber 126, a positive pressure high temperature area is formed in the first chamber 125, and a positive pressure low temperature area is formed in the third chamber 127. Specifically, after the fan 123 is running, the gas in the second chamber 126 enters the fan 123 through the air inlet of the fan 123, and enters the first chamber 125 through the air outlet of the fan 123, and then enters the heat exchanger 124 and enters the third chamber 127 after heat exchange and temperature reduction in the heat exchanger 124, and then enters the air duct 111, and the cold air is transported to the interior of the box through the air duct 111 to provide cold air to the goods arranged in the box 110, and the air inside the box 110 can enter the second chamber 126 through the return air port, so that the gas inside the box 110 forms an internal cycle.

[0054] In this embodiment, in order to increase the air circulation volume in the box 110, an auxiliary fan 130 is further provided in the box 110, and the air outlet of the auxiliary fan 130 is connected to the air duct 111. Specifically, the auxiliary fan 130 is arranged above the evaporator 122, and the air outlet (not shown) of the auxiliary fan 130 is connected to the evaporator 122. More specifically, the auxiliary fan 130 can be arranged between the evaporator 122 and the inner top plate 112. It can be understood that the air inlet (not shown) of the auxiliary fan 130 can be connected to the internal space of the box 110, so that the gas inside the box 110 can enter the auxiliary fan 130 through the air inlet (not shown) of the auxiliary fan 130.

[0055] Specifically, the air outlet of the auxiliary fan 130 can be connected to the first chamber 125, so as to increase the flow rate of the gas entering the heat exchanger 124, so as to increase the air circulation volume inside the box 110. A baffle 118 can also be provided between the evaporator 122 and the inner top plate 112, and the baffle 118 is located on the side of the auxiliary fan 130 away from the end plate 119 and is spaced from the auxiliary fan 130, so as to form a seal between the air outlet of the auxiliary fan 130 and the first chamber 125, so that the high-pressure gas discharged from the air outlet of the auxiliary fan 130 can all enter the first chamber 125.

[0056] In this embodiment, a plurality of auxiliary fans 130 may be disposed in the box body 110 . The air outlets of the plurality of auxiliary fans 130 may all be connected to the first chamber 125 .

[0059] In this embodiment, the auxiliary fans 223 are arranged on both sides of the evaporator 222, and the air outlets of the auxiliary fans 223 are connected to the air duct 211. Specifically, Figure 7 2 shows by way of example that four auxiliary fans 230 are arranged in the housing 210, and two auxiliary fans 230 are arranged on each side of the evaporator 222. A fourth chamber 231 is connected between the two auxiliary fans 230 and the air duct 211, and the air outlets of the two auxiliary fans 230 are respectively connected to the fourth chamber 231, and the fourth chamber 231 is connected to the air duct 211, so that the air outlets of the two auxiliary fans 230 are connected to the air duct 211. The high-pressure gas formed after the operation of the fan 223 directly enters the air duct 211, and the high-pressure gas formed after the operation of the auxiliary fan 230 enters the air duct 211 through the fourth chamber 231, thereby increasing the air circulation volume in the housing 210.
