Description

Technical Field

[0001] This utility model relates to the field of container technology, and more specifically to a refrigerated container. Background Technology

[0002] In the refrigerated container industry, with the diversification of special containers and refrigerated containers, the application of electrical technology in refrigerated containers has become very common. For example, the overhead lighting system, the alarm light system at the end door, and the intelligent electrical cabinet for multi-temperature zones inside the container all ultimately draw power from the refrigeration unit at the front end of the refrigerated container. Therefore, the power and signal cables for all electrical components inside the container are ultimately connected to the refrigeration unit or the electrical cabinet installed at the refrigeration unit for power.

[0003] Because the refrigerated container has a foam layer, for aesthetic reasons, these cables are usually pre-embedded in the foam layer of the top panel of the container. The front and rear ends are connected to the external refrigeration unit and the electrical equipment interface (such as switches) on the rear panel inside the container through the decorative panel. This type of pre-embedded cable in the top panel is now very common.

[0004] The cables embedded in the top panel of existing refrigerated containers are all encased in a corrugated conduit to prevent the cable sheath from being damaged by the high temperatures during the foaming process. Nylon is the most commonly used material for the corrugated conduit, although PVC and aluminum-plastic composite pipes are also used in some cases.

[0005] Overall, nylon corrugated pipes are currently the most widely used. Their material is soft, possessing excellent bending and flexibility, but this advantage comes at the cost of cable replaceability. There are two main reasons for this: First, during the foaming process, the foam compresses the corrugated pipe, easily causing deformation and thus compressing the internal cables. This leaves the cables under continuous pressure after foaming, making them difficult to remove or replace. Second, when cables embedded in the top plate need to be turned 90° to connect to switches on the side plate, the annular grooves on the inner wall of the corrugated pipe form grooves, hindering the cable head from being easily inserted. Even if forced through, it easily causes cable damage or even breakage, ultimately making effective replacement impossible.

[0006] In contrast, aluminum-plastic composite (APC) pipes have higher rigidity due to their smooth inner layer and outer aluminum alloy coating. In scenarios where cables are pre-embedded in a straight line in the ceiling without bending, their smooth inner wall supports subsequent cable replacement. However, APC pipes are ill-suited for 90° turns from the ceiling to the side panel electrical interfaces. This is because APC pipes are too rigid and lack the flexibility and plasticity of nylon corrugated pipes; they are prone to permanent deformation after bending to a certain angle, thus failing to meet cable replacement requirements.

[0007] Therefore, a refrigerated container is needed to at least partially solve the above problems. Utility Model Content

[0025] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings.

[0026] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4This application provides a refrigerated container 100, which includes a side wall 110 and a top wall 120, with the top wall 120 connected to the upper end of the side wall 110. The refrigerated container 100 also includes rigid conduit and metal adapter 130.

[0027] The side wall 110 has multiple through holes. The rigid conduit includes a first tube 141, which extends at least partially within the side wall 110, with its end disposed within the side wall 110. The metal adapter 130 includes a wire-passing portion 131 and a first adapter portion 132, wherein the first adapter portion 132 is connected to the end of the wire-passing portion 131, and a first included angle α is formed between the first adapter portion 132 and the wire-passing portion 131. The metal adapter 130 also includes a first adapter 130A, the wire-passing portion 131 of which is disposed within the side wall 110 and abuts against the first tube 141, and the first adapter portion 132 of the first adapter 130A extends out of the side wall 110 through the through holes.

[0028] According to the refrigerated container 100 of this application, a metal adapter 130 with an elbow is used to connect with a rigid conduit to realize the reversal of the cable in the elbow of the metal adapter 130. Furthermore, the metal adapter 130 and the rigid conduit have high mating strength and will not deform during the foaming process, allowing for the replacement of the cable later.

[0029] refer to Figure 2 and Figure 3 The metal adapter 130 also has a second adapter portion 133, which is connected to the end of the wire-passing portion 131 opposite to the first adapter portion 132. The first adapter portion 132 and the plane containing the wire-passing portion 131 and the second adapter portion 133 form a first included angle α, and the second adapter portion 133 and the wire-passing portion 131 form a second included angle β. The second adapter portion 133 of the first adapter 130A is connected to the first tube 141.

[0030] The first included angle α is preferably 85°~95°. In an optional embodiment, the second included angle β can also be 85°~95°. Preferably, the second included angle β is an obtuse angle. More preferably, the second included angle β is 115°~125°. Thus, by utilizing the first adapter 132, which is approximately perpendicular to the side wall 110, it can be smoothly extended to the corresponding wire hole. Furthermore, the large angle of the second included angle β provides less resistance when threading or replacing cables.

[0031] The rigid conduit is constructed of aluminum-plastic composite, PP, or PVC. Preferably, the rigid conduit is aluminum-plastic composite. The metal adapter 130 can be constructed as a stainless steel adapter. Furthermore, the side wall 110 has an inner side plate, to which the metal adapter 130 is fixedly connected.

[0032] refer to Figure 5 The rigid conduit also includes a second conduit 142, which extends at least partially along the length of the refrigerated container 100 at the junction of the top wall 120 and the side wall 110, with its end located at the junction of the top wall 120 and the side wall 110. The second conduit 142 can be an integral intermediate conduit at the junction, or it can be the end portion of a conduit extending from the top wall 120 towards the side wall 110 at a large angle.

[0033] The metal adapter 130 also includes a second adapter 130B. A second adapter portion 133 and a cable guide portion 131 of the second adapter 130B are disposed in the side wall 110. The second adapter portion 133 of the second adapter 130B abuts against the end of the second tube 142, and the first adapter portion 132 of the second adapter 130B extends out of the side wall 110 through a cable pass-through hole. Thus, the cable in the end of the second tube 142 located at the top can be turned along the side wall 110 and extended into the housing.

[0034] As an optional embodiment, the rigid conduit also includes a third conduit (not shown) disposed in the top wall 120 and extending at an angle to the side wall 110 to the junction of the top wall 120 and the side wall 110. (See reference) Figure 1 The metal adapter 130 also includes a third adapter 130C. A first adapter portion 132 of the third adapter 130C extends into the sidewall 110 and connects to the end of the third tube. The wire-passing portion 131 and the second adapter portion 133 of the third adapter 130C are located within the sidewall 110. Thus, by utilizing the right-angle turn of the first adapter portion 132, the cable in the third tube extending perpendicularly to the sidewall 110 is turned to extend into the sidewall 110. In this embodiment, since the cable in the third tube is turned into the sidewall 110, an additional rigid conduit is needed to connect to the second adapter portion 133 of the metal adapter 130. This additional rigid conduit can form the aforementioned first tube 141. That is, both ends of the rigid conduit in the sidewall 110 can be connected to the second adapter portions 133 of the two metal adapters 130.

[0035] In one implementation, the inner diameter of the metal adapter 130 matches the outer diameter of the rigid conduit, allowing the rigid conduit to be inserted into the metal adapter 130. A securing strap is wrapped around the joint between the metal adapter 130 and the rigid conduit for fixation.

[0036] More specifically, the rigid conduit can have an inner diameter of 20mm and an outer diameter of 25mm. The metal adapter 130 can have an inner diameter of 25mm and an outer diameter of 28mm. When the two are connected, the rigid conduit extends approximately into the metal adapter 130.

[0037] Unless otherwise defined, the technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein is for descriptive purposes only and is not intended to limit the scope of the invention. Features described in one embodiment may be applied, alone or in combination with other features, to another embodiment, unless that feature is not applicable in that other embodiment or is otherwise stated.
