Abstract
Description
Technical Field
[0001] The invention relates to a foldable compressor-free heat-insulating container, belonging to the technical field of logistics equipment. Background Art
[0002] In the prior art, insulated containers used for cold chain transportation generally need to use compressors for refrigeration to ensure that the temperature inside the container is low enough. However, the compressor takes up a large space, making it difficult to achieve effective use of the overall space. Secondly, its refrigeration can only be mainly fully open or fully closed, and the switching time is long. It cannot be directly controlled by PWM, so it is actually impossible to truly achieve accurate temperature control. Due to these two reasons, the comprehensive cost of cold chain transportation in terms of insulated container equipment cost, transportation volume and loss remains high. Summary of the invention
[0003] In order to solve the above technical problems, the present invention provides a foldable compressor-free insulated container. Based on the setting of a refrigeration rod and a detachable box body, the foldable compressor-free insulated container can effectively realize accurate temperature control refrigeration without a compressor, greatly reducing the equipment cost, transportation volume and loss of the insulated container, thereby effectively reducing the overall cost of cold chain transportation.

[0018] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.
[0019] A first embodiment of the present invention relates to Figures 1 to 4 A foldable compressor-free insulated container is shown, comprising a box body 1; a plurality of photovoltaic panels 31 are fixedly mounted on the top of the box body 1, a plurality of cooling rods 32 are mounted in the box body 1 close to the side panels, the photovoltaic panels 31 are connected to the battery 21 for power supply, the battery 21 is connected to the cooling rods 32 for power supply, and the cooling rods 32 are made of semiconductor cooling sheets; the box body 1 is composed of a detachable top panel 11, a bottom panel 12, a rear panel 13, a front panel 14, and a side panel 15 to form a closed box body.
[0020] Therefore, compared with the traditional compressor refrigeration box: ①It can quickly reach the target temperature, realize ultra-low temperature refrigeration and accurately control the temperature; ② It occupies less space than the compressor, which is conducive to the effective use of the overall space of the box; ③ Longer service life and higher equipment reliability; ④ More environmentally friendly and hygienic, the semiconductor adopts physical refrigeration to the stored objects inside the box without any chemical pollution of the refrigerant, which is more suitable for the refrigerated transportation of fruits, vegetables and meat products.
[0021] The second embodiment of the present invention is substantially the same as the first embodiment, mainly in that the top plate 11 has an extension section at the mounting position of the rear panel 13 , and the battery 21 is mounted on the extension section.
[0022] Furthermore, a generator 22 is installed closely to the installation position of the battery 21 , and the generator 22 supplies power to the battery 21 .
[0023] Furthermore, a voltage stabilizing controller 23 is installed at the installation position of the battery 21 , and the photovoltaic panel 31 is connected to the voltage stabilizing controller 23 and charges the battery 21 through the voltage stabilizing controller 23 .
[0024] The solar panel on the top uses a charging and voltage-stabilizing controller to stably and continuously store the energy generated by sunlight when the container is operating outdoors into the battery. The micro gasoline generator is flexibly supplemented by gasoline power generation according to the remaining power in the battery, fully saving fuel costs.
[0025] Furthermore, a temperature controller 24 is installed at the installation position of the battery 21 , and the temperature controller 24 is electrically connected to control the cooling rod 32 .
[0026] Furthermore, the temperature controller 24 is also electrically connected to a temperature sensor 34 , and the temperature sensor 34 is fixed on the bottom surface of the top plate 11 .
[0027] The temperature power controller monitors the ambient temperature inside the box in real time based on the temperature sensor installed inside the box, and controls the connected semiconductor cooling rods to output cooling, achieving precise temperature control while also achieving effective use of energy. Since the cooling rod module uses a parallel circuit, when individual cooling rods are not working, the temperature controller can monitor other cooling rods to work normally and automatically compensate for the cooling power to ensure the overall temperature balance inside the box.
[0028] The third embodiment of the present invention is substantially the same as the first embodiment, mainly in that a plurality of cooling rods 32 are installed in parallel on the inner surfaces of the side plates 15 on both sides.
[0029] Furthermore, there is a slot on the inner surface of the side plate 15, and the cooling rod 32 is correspondingly inserted into the slot for installation. Therefore, the installation and maintenance of the cooling rod 32 are very convenient, and the cold surface of the cooling rod 32 directly faces the cavity space, while the hot surface of the cooling rod 32 can dissipate heat through the side plate 15, which greatly improves the overall structural integration, reduces structural redundancy, and ensures the cooling effect.
[0030] Furthermore, a groove is formed on the top surface of the top plate 11 , and the shape of the groove matches the photovoltaic panel 31 , and a plurality of photovoltaic panels 31 are arranged in parallel.
[0031] Furthermore, the height of the side panels 15 is equal to the width of the bottom panel 12, and the sum of the heights of the rear panel 13 and the front panel 14 is not greater than 1.1 times the length of the bottom panel 12. This ensures that the whole can be folded into a relatively regular flat rectangular shape when folded, and the cold chain transport vehicle can pull more than 5 layers at a time when empty (assembled during transportation, one car and one box), which greatly facilitates transportation planning.
[0032] Therefore, the present invention adopts an inward foldable compressible structure for designing the left and right side bodies. After the front and rear doors are disassembled, they can completely cover the solar panels on the top plate. The folded square body has a neat structure, which is convenient for transportation and storage in various occasions.
