Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation boxes, in particular to a fully assembled passive thermal insulation box internal temperature control chamber structure. Background Art

[0002] With the rapid development of the global cold chain logistics industry, the demand for the storage and transportation of temperature-sensitive goods is growing. In this context, insulated containers, as key equipment in cold chain transportation, have a direct impact on the quality and safety of goods transported. Currently, insulated containers on the market primarily utilize two temperature control methods: active and passive.

[0003] Active temperature control methods typically rely on dedicated temperature control components such as refrigerators. These components require continuous external energy input and pose the risk of temperature runaway in the event of unstable conditions, such as power failures. Furthermore, active temperature control systems consume a lot of energy and have poor environmental adaptability.

[0004] Compared to active temperature control, passive temperature control utilizes the inherent insulating properties of insulation materials to achieve long-term insulation of the goods inside by constructing an effective temperature-controlled container. The advantage of this method is that it avoids dependence on external energy sources, reduces energy consumption, and reduces the risk of temperature loss due to equipment failure. Passive insulated boxes are mainly composed of an external box structure, an internal insulation material layer, and a temperature-control medium layer. The temperature-control medium layer usually uses dry ice or phase change material (PCM) to maintain a stable temperature inside the box.

[0005] However, existing passive insulated boxes have several limitations. First, the fixed size and volume of traditional insulated boxes make it difficult to accommodate cargo of varying sizes and shapes, resulting in low loading efficiency. Second, large insulated boxes, especially pallet-type insulated boxes used in conjunction with forklift pallets, often lack flexibility in their internal structure, making it difficult to meet the changing demands of cargo loading. Furthermore, insulated boxes in the prior art are difficult to operate during loading and unloading, and the temperature control within the box is not precise enough during long-term transportation, which may affect the quality and safety of the cargo.

[0006] To address the shortcomings of existing technologies, those skilled in the art have been seeking a more efficient, flexible, and reliable insulation solution. This solution needs to be adaptable to cargo of varying sizes and shapes, while ensuring excellent insulation performance while enabling easy loading and unloading and precise temperature control. In response to these needs, this utility model proposes a fully assembled passive insulated box temperature control chamber structure, aiming to address the existing issues. Utility Model Content

A hook is provided on the bottom support rod 33, and the hook is used to fix the bottom of the gel-type PCM board hanging bag 2. A connecting rod and a tightening screw are provided on the vertical support rod 32. The vertical support rod 32 is divided into upper and lower vertical support rods 32, and the upper and lower vertical support rods 32 are connected by connecting rods and tightening screws to complete the height switching of the inner frame.

The top support rod 31, vertical support rod 32 and bottom support rod 33 of the support frame 3 are of unified specifications and are aluminum profiles with national standard cross-sectional dimensions.

[0038] The supporting top plate 34 is made of a plastic honeycomb plate with a thickness of 10 mm and is assembled on the top of the inner temperature control chamber supporting frame 3 to support the top gel-type PCM.

[0039] The gel-type PCM board 1 is a plastic film packaging structure with uniform size, placed in a gel-type PCM board hanging bag 2 and laid flat on the supporting top plate 34 .

[0040] The general installation method of the internal temperature control chamber structure is to assemble from bottom to top in sequence. All connections are completed through supporting angle pieces and supporting fasteners. First, the bottom support rod 33 pre-installed with hooks and bases is connected to the overall bottom frame, and the top support rod 31 pre-installed with hooks, bases and supporting top plates 34 is connected to the top frame. Then, the bottom frame and the top frame are connected through the vertical support rod 32. The gel-type PCM board hanging bag 2 is fixed to the top and low frames through the hooks and bases. Finally, the gel-type PCM board is placed in the hanging bag and laid flat on the supporting top plate 34 to complete the construction of the internal temperature control chamber.

[0041] Example 2

[0042] An outer structure of the insulation box is provided on the outside of the support frame 3, including: side panels 4, top panel 5, bottom panel 6 and middle enclosure 7, which cooperate with the internal temperature control chamber structure to realize the switching of the full volume and half volume working states of the insulation box. The side panels 4 are installed with tensioning locks 41 and corner guards 42, which cooperate with the middle enclosure 7 to complete the fixed support interlocking when the upper and lower side panels 4 of the box are disassembled and assembled.

[0043] In this embodiment, the full-volume and half-volume operating modes of the interior and exterior structures are switched by disassembling and assembling the vertical support rods 32 of the internal temperature control chamber structure and the side panels 4 of the exterior structure. In the specific implementation of the half-volume operating mode of the interior and exterior structures, the bottom plate 6 is arranged in sequence, the bottom support rods 33 are connected and arranged above the bottom plate 6, the lower vertical support rods 32 are connected, the bottom support rods 33 and the top support rods 31 are connected via the vertical support rods 32, the top support plate 34 is connected to the top support rods 31, the cargo is placed on the top surface of the bottom plate 6, the gel-type PCM panel hanging bag 2 is fixed to the top support rods 31 and the bottom support rods 33 using hooks, the lower gel-type PCM panel 1 is placed in the gel-type PCM panel hanging bag 2, the top gel-type PCM panel is horizontally placed on the top support rod 34, the lower side panels 4 are arranged, the top panel 5 is covered, and the tightening locks on the side panels 4 are tightened to complete the assembly of the interior and exterior structures in the half-volume operating mode.

This process is completely reversible. The implementation steps of converting the full-volume working state of the internal and external structure of the box to the half-volume working state are the reverse operations of the above specific implementation.

[0045] In this embodiment, the top support rods 31, vertical support rods 32, and bottom support rods 33 of the support frame within the internal temperature-controlled chamber structure are all standard aluminum profiles with a cross-sectional size of 30*30*1.8mm.
