Abstract
Description
Technical Field
[0001] The utility model belongs to the field of railway containers, and in particular relates to a heat-insulating heat-collecting container. Background Art
[0002] Railway container transportation has been widely used in various aspects such as national defense science and technology construction, transportation industry, and medical scientific research. However, since containers are generally closed boxes, their internal environment is easily affected by the external environment, and the internal environmental conditions are relatively worse. Therefore, how to ensure the safety of transportation in order to better adapt to and meet the needs of actual social production is an urgent problem faced by the railway department. Among all the factors that affect the conditions of cargo transportation, temperature is the most important factor affecting container transportation. In railway container transportation, high and low temperature weather will affect the goods inside the container. In the plateau environment, the temperature is often too low. Some goods will be affected by the low temperature and the use of them cannot be guaranteed. The safety and effectiveness of railway container transportation cannot be guaranteed.
[0003] Taking the above problems into consideration, the present invention designs a railway insulated heat-collecting container, which solves the problem of heat preservation and heat collection of containers in high-cold environments. Taking full advantage of the strong solar radiation in plateau environments, light energy is converted into heat energy and transferred into the interior of the container, so as to avoid the situation where the temperature of the container is too low due to being in high-cold conditions for a long time, which affects the normal use of the goods in the container. The present invention also takes into account the problem of unified operation of containers. Its external structure is the same as that of ordinary railway containers, which is convenient for loading and unloading operations and will not affect the efficiency of railway operations. In addition, the present invention also takes into account the problem of corrosion prevention, preventing certain goods from corroding and damaging the box body, so as to extend the life of the product, ensure the safe and effective transportation of goods in high-cold environments, and improve the reliability of railway container transportation.

[0019] The following will be combined with the embodiment of the present utility model Figure 1-Figure 4 , the technical solutions in the embodiments of the utility model are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.
[0020] A heat-insulating heat-collecting container, comprising a container body 1 and a heat-collecting device 2;
[0021] A mounting hole adapted to the heat collecting device 2 is opened on the side of the box body 1 , and the heat collecting device 2 is fixed in the mounting hole. The heat collecting device 2 is used to receive irradiated heat to achieve heat collection inside the box body 1 .
[0022] Furthermore, the heat collecting device 2 includes a light-transmitting layer 3, an air interlayer 4 and a heat-absorbing plate 5 from the outside to the inside.
[0023] Furthermore, the heat absorbing plate 5 is provided with a black nickel coating.
[0024] Furthermore, a fin base surface 8 is provided at intervals inside the heat absorbing plate 5 , and a plurality of heat-conducting metal tubes 6 are provided between the fin base surface 8 and the heat absorbing plate 5 .
[0025] Furthermore, a heat insulating material 7 is filled between the fin base surface 8 and the heat absorbing plate 5 .
[0026] Furthermore, a plurality of fins 9 are fixedly disposed on the inner side of the fin base surface 8 .
[0027] Furthermore, heat transfer oil is arranged in the heat transfer metal pipe 6 .
[0028] Furthermore, the wall surface of the box body 1 includes a box body outer shell 10, a heat-insulating interlayer 11 and a box body inner shell 12 in sequence from the outside to the inside.
[0029] The specific structure of the utility model is as follows:
[0030] The box body 1 is mainly composed of three parts: the box shell 10, the insulation interlayer 11 and the box inner shell 12. The outer shell is made of ordinary steel container materials. Steel containers have the advantages of firm structure, high strength, good water tightness and high weldability. The insulation interlayer 11 requires materials with large thermal resistance. Rock wool glass cloth has the characteristics of small volume weight, good thermal insulation performance and low price. Its thermal conductivity at 0°C is only 0.031W / (mK), which can effectively prevent the loss of internal heat at low temperatures and effectively ensure the relative stability of the temperature inside the liner bag. The box inner shell 12 is also made of ordinary steel container materials, but the steel material has poor corrosion resistance. A 0.4mm thick epoxy resin coating must be applied to the inner surface of the box to prevent corrosion to the box when transporting certain corrosive goods, which affects its use.
[0031] The heat collecting device 2 includes a light-transmitting layer 3, a heat-absorbing plate 5, a heat-conducting metal tube 6, and a fin 9 with a rectangular cross section and straight ribs. The heat collecting device 2 is preferably distributed on the top of the box 1, and can receive sunlight, other irradiation heat sources, etc. For the light-transmitting layer 3, a tempered glass with a length of 1m, a width of 1m, and a thickness of 50mm is used, so that not only can the sunlight be radiated smoothly onto the heat-absorbing plate 5, but the air itself has a large thermal resistance and is a good insulation material. While utilizing the greenhouse effect, it reduces the convection heat loss with the outside world.
[0032] For the heat absorbing plate 5, its surface size is the same as that of the light-transmitting layer 3, and its material needs to have a good absorption capacity for solar radiation, so a 10mm thick copper material is used, and a 0.9mm thick black nickel coating is plated on it to improve the spectral absorption rate. For the heat-conducting metal tube 6, it needs to have good thermal conductivity, and aluminum alloy has excellent thermal conductivity, so the heat-conducting metal tube 6 can use an aluminum alloy material with a diameter of 20mm and a wall thickness of 2mm, and internally sealed heat-conducting oil as a heat-conducting liquid. As for the space between the heat absorbing plate 5 and the fins 9, rock wool glass cloth is filled in the gap between the heat-conducting metal tubes 6 as an insulating material 7 to prevent heat loss. For the fins 9, under the condition that the heat transfer coefficient of the convective heat transfer surface is inconvenient, increasing the heat exchange area is an effective method to enhance heat transfer, so fins can be used to increase the heat exchange area and speed up the rate of heat transfer into the container. The fins 9 are still made of aluminum alloy material, and their basic surface size is the same as that of the light-transmitting layer, 10mm thick, and 25mm thick fins are placed on it. The fins are 100mm high and 1m long.
[0033] like Figure 1 The figure shows the structure of the railway thermal insulation container. Figure 2 This is a schematic diagram of the location of the railway thermal insulation container heat collection device. Figure 3The schematic diagram of the heat collecting device is shown in FIG. 1 . The box 1 and the heat collecting device 2 are mainly connected by screws. The light-transmitting layer 3 is made of 50 mm thick tempered glass, and the position is 5 mm lower than the box shell 10 to prevent the light-transmitting layer from being subjected to excessive pressure. There is a 50 mm thick air interlayer 4 between the light-transmitting layer and the heat absorbing plate 5. In this way, not only can the sunlight be radiated to the heat absorbing plate smoothly, but the air itself has a large thermal resistance and is a good insulation material. While utilizing the greenhouse effect, it reduces the convection heat loss with the outside world. The heat absorbing plate is made of 10 mm thick copper material, which is plated with a 0.9 mm thick coating of black nickel to improve the heat absorption efficiency. A cylindrical heat-conducting metal pipe 6 with a length of 1 m, a diameter of 20 mm, and a wall thickness of 2 mm is placed between the heat absorbing plate 5 and the fin base surface 8. The heat-conducting metal pipe is placed every 50 mm, and the heat-conducting oil is sealed inside as the heat-conducting liquid. It is placed between the heat absorbing plate and the rectangular cross-section straight ribs. The gap between the heat-conducting metal pipes is filled with rock wool glass cloth as an insulation material to prevent heat loss. The fin base surface 8 and the fin 9 need to be cast as one piece with aluminum alloy. The base surface is 1m long, 1m wide and 10mm thick. The fins are arranged every 37.5mm. Each fin is 25mm thick, 100mm high and 1m long. Figure 4 Schematic diagram of box material: the outer shell 10 and the inner shell 12 are both made of steel, the middle insulation interlayer is made of rock wool glass cloth to prevent heat loss in the box, and the inner surface of the inner shell is coated with 0.4mm thick epoxy resin paint to prevent corrosion to the box when transporting certain corrosive goods, thereby affecting its use.
[0034] The equipment fully considers the characteristics of the plateau environment and utilizes its strong solar radiation to achieve heat preservation and heat collection inside the railway container under severe cold conditions, solving the problem that the quality of goods is easily affected by temperature during railway container transportation. The required materials are relatively common and low in cost, saving transportation costs. In addition, the external structure of the equipment is not much different from that of ordinary railway containers, and will not affect the normal operation of railway freight operations. In addition, the problem of corrosion protection is taken into consideration to extend the service life of the product.
[0035] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations, modifications, and substitutions made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
