Abstract
Description
Technical Field
[0001] This application relates to the field of logistics storage and transportation equipment technology, and in particular to a tank heat exchange system and a tank storage and transportation equipment. Background Technology
[0002] In order to preserve the loaded goods effectively, tank storage and transportation equipment typically requires temperature control within the equipment. Current technology generally achieves temperature control by installing heat exchange pipes outside or inside the tank, allowing heat exchange between the tank and the heat exchange medium within these pipes.
[0003] Tanks are typically used to store liquids. The heat exchange pipes located inside the tank make its internal structure complex, difficult to clean, and prone to cross-contamination when storing different items. Existing tank storage and transportation equipment with heat exchange pipes located outside the tank uses semi-enclosed pipe fittings welded to the outer surface of the tank to form a closed flow channel. During operation, the heat exchange pipes carry heat exchange media such as steam, hot water, or ethylene glycol. In the welded structure of these pipes, the heat exchange media comes into direct contact with the tank. Impurities and chloride ions in the heat exchange media, under high temperature and pressure, can chemically react with the tank wall metal, potentially corroding the heat exchange pipe base material and welds, and even posing a risk of tank wall leakage.

To make the purpose, technical solution, and effects of this application clearer and more explicit, the following detailed description is provided with reference to the accompanying drawings and embodiments.

[0039] Tank storage and transportation equipment is a type of mobile container used for storing and transporting various liquid food and chemical products. The properties or state of the goods stored in these containers may change under high or low temperatures. For example, milk will spoil at high temperatures, and vegetable oil will solidify and become unusable at low temperatures. Therefore, tank storage and transportation equipment requires heating, cooling, or temperature control within a preset range during storage, transportation, loading, and unloading. Heat exchange equipment installed outside or inside the tank body allows for heat exchange with the tank, thereby controlling the internal temperature and minimizing changes in the properties of the goods inside.
[0040] This application provides a tank-type storage and transportation equipment, including a tank container heat exchange system capable of insulating objects stored inside the tank to extend their shelf life. The equipment also includes a vehicle body capable of carrying the tank container heat exchange system.
[0041] For details, please refer to Figure 1 The tank heat exchange system includes a tank body 1 and heat exchange tubes 2. A heat exchange medium can flow through the heat exchange tubes 2, so that the heat exchange tubes 2 can exchange heat with the tank body 1, thereby controlling the temperature inside the tank body 1.
[0042] The heat exchange tube 2 is located on the outer wall of the tank body 1, which avoids increasing the complexity of the internal structure of the tank body 1 by placing the heat exchange tube 2 inside the tank body 1, increasing the difficulty of cleaning the inside of the tank body 1, and reducing the risk of cross-contamination of the contents inside the tank body 1.
[0043] At least part of the heat exchange tube 2 is connected to the outer wall of the tank 1 so that heat can be transferred between the heat exchange tube 2 and the tank 1. The heat exchange tube 2 is in direct contact with the tank 1 to transfer heat, which ensures the heat exchange effect between the heat exchange tube 2 and the tank 1.
[0044] A flow channel space 21 is formed inside the heat exchange tube 2, in which the heat exchange medium can flow to achieve heat transfer with the tank 1. The flow channel space 21 is isolated from the tank 1, that is, the heat exchange tube 2 is a closed pipe, which avoids the heat exchange medium from contacting the tank 1 and causing corrosion to the tank 1, thus improving the safety of the storage and transportation equipment.
[0045] In some embodiments, the heat exchange medium can be selected from steam, hot water, or ethylene glycol, etc. The specific choice depends on the actual heat exchange requirements. For example, steam has high thermal efficiency and heating speed, making it a suitable heat exchange medium when heating the contents of tank 1 is required. Conversely, ethylene glycol has a low freezing point and good thermal stability, making it a suitable cooling medium when cooling the contents of tank 1 is required. Furthermore, the selection of the heat exchange medium must also consider its chemical stability, corrosiveness to the materials of the storage and transportation equipment, and economic factors.
[0046] like Figures 2 to 4 As shown, in some embodiments, the heat exchange tube 2 includes multiple heat exchange sub-tubes 22 and connectors 23, with adjacent heat exchange sub-tubes 22 connected by connectors 23. The heat exchange tube 2 is constructed by connecting the heat exchange sub-tubes 22 and connectors 23 into one unit, which facilitates the arrangement of the pipeline and reduces the manufacturing difficulty of the heat exchange tube 2.
[0047] like Figure 2As shown, in some embodiments, the heat exchange sub-tubes 22 extend axially along the tank body 1, and multiple heat exchange sub-tubes 22 are connected sequentially and distributed circumferentially along the tank body 1. The heat exchange sub-tubes 22 are connected in series, and the connector 23 between two adjacent heat exchange sub-tubes 22 can be a bend, which can be connected to the heat exchange sub-tube 22 by a quick coupling to improve assembly efficiency. In the above structure, the heat exchange medium flows axially along the tank body 1 and circumferentially rotates around the tank body 1, improving the uniformity of the heat exchange effect of the heat exchange medium on the tank body 1 along the axial direction.
[0048] like Figure 3 As shown, in some embodiments, the heat exchange sub-tubes 22 extend circumferentially along the tank body 1, and multiple heat exchange sub-tubes 22 are connected sequentially and distributed along the axial direction of the tank body 1. The heat exchange sub-tubes 22 are connected in series, and adjacent heat exchange sub-tubes 22 can be connected by bends. Quick couplings can be used to connect the bends to the heat exchange sub-tubes 22 to improve assembly efficiency. In the above structure, the heat exchange medium rotates circumferentially around the tank body 1 and flows axially towards the tank body 1, improving the uniformity of the radial heat exchange effect of the heat exchange medium on the tank body 1.
[0049] like Figure 4 As shown, in some embodiments, at least two heat exchange sub-tubes 22 are connected in parallel to form a heat exchange tube group, and adjacent heat exchange tube groups are connected in series. Exemplarily, a heat exchange tube group can be composed of two, three, four, or even more heat exchange sub-tubes 22. The heat exchange sub-tubes 22 can extend axially or circumferentially along the tank 1. The heat exchange sub-tubes 22 employ a combination of parallel and series connections, allowing the heat exchange medium to flow simultaneously in at least two heat exchange sub-tubes 22, thereby improving the heat exchange efficiency of the heat exchange medium to the tank 1.
[0050] like Figure 5 As shown, in some embodiments, the heat exchange sub-tube 22 includes a first sub-pipe 22a and a second sub-pipe 22b, which are arranged side by side and connected at their closest points. The arrangement of the heat exchange sub-tube 22 with the first sub-pipe 22a and the second sub-pipe 22b connected side by side along the extension direction increases the pressure-bearing capacity of the heat exchange tube 2.
[0051] like Figure 6As shown in the figure, the heat exchange sub-tube 22 includes a connection part 221, a transition part 222 and a heat exchange part 223. Connection parts 221 are provided at both ends of the heat exchange sub-tube 22. One end of the connection part 221 is connected to one end of the heat exchange part 223 through the transition part 222. The transition part 222 gradually changes along its extension direction and smoothly transitions with the heat exchange part 223 and the connection part 221 respectively. The connection part 221, the transition part 222 and the heat exchange part 223 can be integrally formed to improve the sealing performance and integrity of the heat exchange sub-tube 22. The heat exchange part 223 and the connection part 221 have different cross-sections. The cross-section of the heat exchange part 223 is a non-circular structure, and the cross-section of the connection part 221 is arranged as an annular shape. The inner surface of the pipe connector used between the heat exchange sub-tubes 22 is generally cylindrical. The connection part 221 with a circular cross-section is provided at both ends of the heat exchange sub-tube 22, which facilitates the connection between the heat exchange sub-tube 22 and the connector 23 and can improve the connection sealing performance between the heat exchange sub-tube 22 and the connector 23. The shape of the inner surface of the transition part 222 gradually transitions from the shape of the inner surface of the heat exchange part 223 to the shape of the inner surface of the connection part 221 along its extension direction. This not only enables the side of the heat exchange part 223 connected to the tank body 1 to have a larger contact surface, but also enables the inner wall of the heat exchange part 223 and the inner wall of the connection part 221 to smoothly transition, avoiding the disturbance of the heat exchange medium by the pipe wall and ensuring the stability of the heat exchange effect between the heat exchange tube 2 and the tank body 1.
[0052] Further, as Figure 1 shown in the figure, in some embodiments, the cross-section of the heat exchange tube 2 includes a first straight line segment 2231a, a first arc segment 2232a and a second arc segment 2233a. The first straight line segment 2231a is connected to the outer wall of the tank body 1. A first arc segment 2232a is provided at each end of the first straight line segment 2231a. The second arc segment 2233a is provided between the two first arc segments 2232a and is arranged opposite to the first straight line segment 2231a. The first straight line segment 2231a, the first arc segment 2232a and the second arc segment 2233a are smoothly transitioned. The surface of the heat exchange tube 2 not connected to the tank body 1 is set as an arc surface, which improves the smoothness of the surface of the heat exchange tube 2.
[0053] Further, the inner radius of the first arc segment 2232a is R1, and the inner radius of the second arc segment 2233a is R2, and R1 < R2. In this way, when the flow area inside the heat exchange tube 2 is certain, the length of the first straight line segment 2231a opposite to the second arc segment 2233a is larger, and the heat exchange tube 2 has a larger contact area with the outer wall of the tank body 1, improving the heat exchange effect. The radius of R1 is smaller, that is, the distance between the outer side of the heat exchange tube 2 and the tank body 1 is smaller, which improves the compactness between the heat exchange tube 2 and the tank body 1 and the integrity of the storage and transportation equipment to a certain extent.
[0054] As Figure 7As shown, in some other embodiments, the cross-section of the heat exchange tube 2 includes a first straight segment 2231b, a second straight segment 2234b, a first arc segment 2232b, and a second arc segment 2233b. The first straight segment 2231b and the second straight segment 2234b are disposed close to the tank body 1, and at least a part of the first straight segment 2231b and the second straight segment 2234b are connected to the outer wall of the tank body 1. The first straight segment 2231b and the second straight segment 2234b are connected and disposed at an angle. The other ends of the first straight segment 2231b and the second straight segment 2234b are respectively connected to a first arc segment 2232b. The second arc segment 2233b is connected between the two first arc segments 2232b and is disposed opposite to the first straight segment 2231b and the second straight segment 2234b. A bending structure directed into the heat exchange tube 2 is formed between the first straight segment 2231b and the second straight segment 2234b. After a heat exchange medium is introduced into the heat exchange tube 2, the bending structure will deform, so that the first straight segment 2231b and the second straight segment 2234b can be tightly attached to the outer wall of the tank body 1. The connection structure of the first straight segment 2231b and the second straight segment 2234b provides a deformation space for the heat exchange tube 2 and improves the pressure-bearing capacity of the heat exchange tube 2 channel.
[0055] The included angle between the first straight segment 2231b and the second straight segment 2234b is greater than 120°. Exemplarily, the included angle between the first straight segment 2231b and the second straight segment 2234b can be but is not limited to 120°, 125°, 130°, 140°, 145°, 150°, etc. On the basis of satisfying the deformation effect of the first straight segment 2231b and the second straight segment 2234b, a larger included angle can be set between the first straight segment 2231b and the second straight segment 2234b to reduce the distance between the heat exchange tube 2 and the tank body 1 and ensure a good heat exchange effect between the heat exchange tube 2 and the tank body 1.
[0056] Further, the inner radius of the first arc segment 2232b is R1, and the inner radius of the second arc segment 2233b is R2, and R1 < R2. In this way, when the flow area inside the heat exchange tube 2 is certain, the length of the first straight segment 2231b opposite to the second arc segment 2233b is larger, and the heat exchange tube 2 has a larger contact area with the outer wall of the tank body 1, improving the heat exchange effect. And the radius of R1 is smaller, that is, the distance between the outer side of the heat exchange tube 2 and the tank body 1 is smaller, which improves the compactness between the heat exchange tube 2 and the tank body 1 and the integrity of the storage and transportation equipment to a certain extent.
[0057] As Figure 8As shown, in some other embodiments, the cross-section of the heat exchange tube 2 includes a first arc segment 2232c, a second arc segment 2233c, and a third arc segment 2235c. The third arc segment 2235c abuts against the outer wall of the tank body 1. A first arc segment 2232c is provided at each end of the third arc segment 2235c. The second arc segment 2233c is provided between the two first arc segments 2232c and is disposed opposite to the third arc segment 2235c. The first arc segment 2232c, the second arc segment 2233c, and the third arc segment 2235c are in smooth transition, ensuring that the heat exchange medium can flow stably in the heat exchange tube 2. One side of the heat exchange tube 2 connected to the tank body 1 is set as an arc surface, improving the connection compactness between the heat exchange tube 2 and the tank body 1, thereby enhancing the heat exchange effect between the heat exchange tube 2 and the tank body 1.
[0058] Furthermore, the inner radius of the first arc segment 2232c is R1, the inner radius of the second arc segment 2233c is R2, and the inner radius of the third arc segment 2235c is R3, and R1 < R2 < R3; thus, a relatively large contact area is formed between the heat exchange tube 2 and the outer wall of the tank body 1, improving the heat exchange efficiency between the heat exchange tube 2 and the tank body 1 to a certain extent.
[0059] In the above, the structure of the cross-section of the heat exchange tube 2 is the structure of the cross-section of the heat exchange part 223 of the heat exchange sub-tube 22.
[0060] The heat exchange tube 2 can be connected to the tank body 1 by various fixing methods, with high flexibility and improving the assembly efficiency of the storage and transportation equipment.
[0061] As Figure 9 shown, in some embodiments, the heat exchange tube 2 and the tank body 1 can be connected by intermittent welding. That is, spaced welding points 6 can be respectively provided on both sides of the side walls of the heat exchange tube 2 and the tank body 1 that are close to each other. Compared with the full-welding connection method, the intermittent welding method is faster and can meet the stable connection between the heat exchange tube 2 and the outer wall of the tank body 1.
[0062] ]>As Figures 10 to 14 shown, in some embodiments, the storage and transportation equipment may include a fixing member 3, and the heat exchange tube 2 is connected to the tank body 1 through the fixing member 3. In this way, a detachable structure is adopted between the heat exchange tube 2 and the tank body 1, facilitating the disassembly, assembly, and maintenance of the heat exchange tube 2.
[0063] As Figure 10 and Figure 12 shown, the fixing member 3 abuts against the side of the heat exchange tube 2 away from the tank body 1, and both ends of the fixing member 3 are respectively connected to the tank body 1 through fasteners 4. The fixing member 3 abuts the heat exchange tube 2 against the tank body 1, which not only ensures the stable connection between the heat exchange tube 2 and the tank body 1 but also guarantees the heat exchange effect between the heat exchange tube 2 and the tank body 1.
[0064] In some embodiments, the fixing member 3 has through holes at both ends, and bolts are welded to the tank body 1 at positions opposite to the through holes. The fastener 4 is a nut with internal threads that is compatible with the bolts. When fixing the heat exchange tube 2 to the tank body 1, the fixing member 3 presses the heat exchange tube 2 against the outer wall of the tank body 1. The bolts on the tank body 1 pass through the through holes at both ends of the fixing member 3, and then the nuts are fitted onto the bolts and tightened to complete the fixing of the heat exchange tube 2. If it is necessary to remove the heat exchange tube 2, the above steps are reversed.
[0065] like Figure 13 and Figure 14 As shown, in some embodiments, one end of the fixing member 3 is connected to the tank body 1 via a fastener 4, and the other end of the fixing member 3 is arc-shaped and closely fitted to the heat exchange tube 2. Specifically, one end of the fixing member 3 may have a through hole, and a bolt corresponding to the through hole is welded to the outer wall of the tank body 1. The fastener 4 may be a nut compatible with the bolt. When installing the heat exchange tube 2, the heat exchange tube 2 is fixed by abutting it between the fixing member 3 and the tank body 1, then passing the bolt through the through hole of the fixing member 3, and tightening the nut. Only one end of the fixing member 3 needs to be installed when installing the heat exchange tube 2, improving the convenience of fixing the heat exchange tube 2.
[0066] Multiple fasteners 3 can be provided, and multiple fasteners 3 are distributed sequentially along the extension direction of heat exchange tube 2 to ensure that heat exchange tube 2 can be stably connected to tank 1 in the extension direction.
[0067] Furthermore, such as Figure 12 As shown, the storage and transportation equipment also includes a heat-conducting component 5, which is disposed between the heat exchange tube 2 and the tank 1. The heat-conducting component 5 can be made of heat-conducting putty or heat-conducting felt, etc. The heat-conducting putty or heat-conducting felt can fill the gap between the heat exchange tube 2 and the tank 1. This not only reduces the gap between the heat exchange tube 2 and the tank 1, but also, because the heat-conducting component 5 has good thermal conductivity, it can efficiently transfer heat from the heat exchange tube 2 to the tank 1, improving heat utilization. Furthermore, the use of the heat-conducting component 5 can reduce heat loss and improve the energy efficiency of the entire storage and transportation equipment.
[0068] like Figure 15 As shown, the heat exchange tube 2 is connected to the tank 1 by adhesive 7. Adhesive 7 not only has sufficient bonding strength to ensure the stability of the connection between the heat exchange tube 2 and the tank 1, but also has a certain degree of elasticity to accommodate the slight deformation caused by temperature changes between the heat exchange tube 2 and the tank 1, thereby maintaining the reliability of the connection.
[0069] When installing the heat exchange tube 2, apply adhesive 7 evenly to the outer wall of the heat exchange tube 2 facing the tank 1 and the outer wall of the tank 1, and then press the heat exchange tube 2 tightly onto the tank 1. The adhesive force of the adhesive 7 achieves a tight connection between the heat exchange tube 2 and the tank 1.
[0070] The selection of adhesive 7 should take into account its temperature resistance and chemical stability to ensure that adhesive 7 can maintain its performance for a long time under the working temperature and medium environment of the storage and transportation equipment, thereby extending the service life of the storage and transportation equipment.
[0071] In summary, this application, by setting heat exchange tubes with enclosed flow channel spaces on the outer wall of the tank, ensures that the heat exchange medium flowing inside the heat exchange tubes does not directly contact the outer wall of the tank, effectively preventing the heat exchange medium from corroding and contaminating the tank wall.
[0072] The connection between the closed heat exchange tube structure and the tank can be achieved by intermittent welding, fixing with fasteners, or adhesive fixing, eliminating the need for traditional continuous welding. This reduces the workload of connecting the heat exchange tubes and the tank, improves the production efficiency of storage and transportation equipment, and also reduces the risk of weld corrosion.
[0073] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and concept of this application, and all such substitutions or changes should fall within the protection scope of the appended claims.
