[0049] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the present invention, the specific implementation method, structure, characteristics and effects proposed by the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0050] The utility model provides an I-shaped radiator core structure, which comprises: a first connecting tube 1, a second connecting tube 2, and a third heat dissipation core tube 3 arranged between the first connecting tube 1 and the second connecting tube 2; the first connecting tube 1, the second connecting tube 2 and the third heat dissipation core tube 3 are internally connected and integrally formed to form an I-shaped structure; annular grooves 4 are provided on the inner walls of the tube openings at both ends of the first connecting tube 1 and the second connecting tube 2; a first internal thread 51 is provided in the annular groove 4 on the same side of the first connecting tube 1 and the second connecting tube 2; a second internal thread 52 is provided in the annular groove 4 on the other side of the first connecting tube 1 and the second connecting tube 2.

[0051] In this embodiment, the first connecting tube 1 and the second connecting tube 2 are respectively arranged in parallel up and down, and the third heat dissipation core tube 3 between the first connecting tube 1 and the second connecting tube 2 can be placed vertically or tilted to form a similar "I-shaped structure", and the two ends of the third heat dissipation core tube 3 are respectively integrally formed with the first connecting tube 1 and the second connecting tube 2 and are internally connected. The first connecting tube 1, the second connecting tube 2 and the third heat dissipation core tube 3 are not limited to the selection of round tubes and square tubes, and the variable inner diameter tubes composed of round tubes and square tubes. The inner diameters of the first connecting tube 1 and the second connecting tube 2 can be the same or different. For example, the first connecting tube 1 is at the top, the second connecting tube 2 is at the bottom, and the inner diameter of the second connecting tube 2 is greater than the inner diameter of the first connecting tube 1. The third heat dissipation core tube 3 includes: any one or more combinations of straight tubes, arc tubes and curved tubes, which are not specifically limited here. The annular groove 4 is set according to the outer diameters of the tube openings at both ends of the first connecting tube 1 and the second connecting tube 2. Generally, the thickness of the tube opening at the annular groove 4 is not less than 5 cm to avoid the structural strength at the tube opening at the annular groove 4. The length or inner diameter of the annular groove 4 at one end of the first connecting tube 1 may be the same as or different from the length or inner diameter of the annular groove 4 at the other end of the first connecting tube 1. The length or inner diameter of the annular groove 4 in the first connecting tube 1 may be the same as or different from the length or inner diameter of the annular groove 4 in the second connecting tube 2. The actual size of the length and / or inner diameter of the annular groove 4 depends on the specific implementation situation and will not be repeated here.

[0052] In this embodiment, the length of the internal thread provided in each annular groove 4 is the same as the length of the corresponding annular groove. For example, the length of the first internal thread 51 is the same as the length of the corresponding annular groove 4, and the height of the first internal thread 51 is not greater than the height of the step of the corresponding annular groove 4 in the radial direction. Figure 1 and Figure 2 As shown, in order to reduce the cost of mass production, simplify processing and assembly by using unified parts and reduce the labor intensity of operation, the depth of the annular groove 4 on the first connecting pipe 1 and the second connecting pipe 2 along the tube axis direction, the inner diameter of the annular groove 4, and the height of the step of the annular groove 4 in the radial direction are all set to be consistent.

[0053] As an optional implementation, Figure 1 and Figure 2 As shown, the first connecting tube 1 and the second connecting tube 2 have the same structure. The first connecting tube 1 and the second connecting tube 2 adopt the same length, inner diameter and wall thickness structural dimensions, so that the produced I-shaped radiator core structure is easy to connect, and adopts a universal structural dimension, which is more convenient and efficient during use and assembly.

[0054] As an optional implementation, Figure 1 and Figure 2As shown, the length of the first internal thread 51 is the same as the length of the second internal thread 52; and the lead of the first internal thread 51 is the same as the lead of the second internal thread 52, and the winding direction of the spiral line is opposite. The utility model sets the first internal thread 51 and the second internal thread 52 as opposite structures, so that when the I-shaped radiator core structure is assembled and connected, the first internal thread 51 and the corresponding second internal thread 52 can be connected and assembled at the same time by using an adaptive connector, thereby improving the assembly efficiency.

[0055] As an optional implementation, Figure 1 and Figure 2 As shown, the inner diameter of the third heat dissipation core tube 3 is not greater than the inner diameter of the first connecting tube 1 or the second connecting tube 2. In actual production and use, the first connecting tube 1 is generally located at the upper part for input circulation of incoming water; the second connecting tube 2 is located at the lower part for output of circulating water in the I-shaped radiator core structure. The inner diameter of the third heat dissipation core tube 3 located between the first connecting tube 1 and the second connecting tube 2 is not greater than the inner diameter of the first connecting tube 1 or the second connecting tube 2, so as to ensure that the hot water entering the first connecting tube 1 is fully circulated and dissipated in the third heat dissipation core tube 3, and the low-temperature water cooled after circulating heat dissipation is then transported to the second connecting tube 2 through the water outlet at the bottom of the third heat dissipation core tube 3 for output, so as to ensure that the hot water entering from the first connecting tube 1 can be fully dissipated and cooled and then output through the second connecting tube 2.

[0056] As an optional implementation, Figure 1 and Figure 2 As shown, the height of the third heat dissipation core tube 3 is in the range of 20cm to 180cm. The size and height range of the third heat dissipation core tube 3 is, on the one hand, convenient for production and improving production efficiency; on the other hand, convenient for transportation and assembly and reducing transportation and assembly costs. As a preferred real-time method, the height of the third heat dissipation core tube 3 is in the range of 40cm to 60cm. When the height of the third heat dissipation core tube 3 is in this height range, in addition to being suitable for transportation, it is more suitable for arrangement and application during heating. When the height of the third heat dissipation core tube 3 is at any value of 40cm to 60cm, it is more suitable for subsequent processing of the I-shaped radiator core structure of this size and application in various application scenarios requiring heating.

[0059] As an optional implementation, when the third heat dissipation core tubes 3 are a plurality of straight tubes, they can be arranged in parallel at a certain interval along the space between the first connecting tube 1 and the second connecting tube 2, which will not be described in detail here.

[0061] In this embodiment, the angle generally ranges from 15° to 75°, and the angle of the elbow is not limited to any value in the range of 90° to 150°. The above-mentioned structural arrangement can ensure that when multiple I-shaped radiator core structures are connected and expanded along the axis of the first connecting tube 1 and the second connecting tube 2, the spacing between adjacent third heat dissipation core tubes 3 remains consistent. In addition to being an angled elbow with a certain angle, the above-mentioned elbow can also be an arc tube to further increase the surface area of ​​heat dissipation on the outer surface of the I-shaped radiator core structure.

[0062] As another preferred embodiment, when the above-mentioned angle is 90° and the bending angle of the elbow is 120-150°, on the one hand, it can ensure that the heat dissipation distance between the two third heat dissipation core tubes 3 meets the heat dissipation requirements, which is conducive to sufficient heat dissipation; on the other hand, when the connection and expansion are carried out along the axis of the first connecting tube 1 and the second connecting tube 2, it is also possible to ensure that the distance between adjacent third heat dissipation core tubes 3 remains consistent.

[0063] As an optional implementation, Figure 4 As shown, there are three third heat dissipation core tubes 3; the three third heat dissipation core tubes 3 include a straight tube, and third heat dissipation core tubes 3 with bent tubes symmetrically arranged on both sides of the straight tube; a distance is maintained between the three third heat dissipation core tubes 3; the axis of the straight tube is consistent with the intersection line of the first plane and the second plane.

[0064] The angle of the bend is not limited to any angle greater than 90° to 150°, and can also be a right angle, such as similar to Figure 5 The third heat dissipation core tubes 3 with right-angle bends on both sides are not described in detail here.

[0065] As an optional embodiment, the number of the third heat dissipation core tubes 3 is three; the three third heat dissipation core tubes 3 include a straight tube, and a third heat dissipation core tube 3 with a bent tube symmetrically arranged on one side of the straight tube; a certain angle is maintained between the two third heat dissipation core tubes 3 with bent tubes; the axis of the straight tube and the intersection line of the plane formed by the two third heat dissipation core tubes 3 with bent tubes are consistent.

[0066] As an optional embodiment, the number of the third heat dissipation core tubes 3 is three; the three third heat dissipation core tubes 3 include a straight tube, and a third heat dissipation core tube 3 with a bent tube symmetrically arranged on one side of the straight tube; a certain angle is maintained between the two third heat dissipation core tubes 3 with bent tubes; the axis of the straight tube and the intersection line of the plane formed by the two third heat dissipation core tubes 3 with bent tubes are consistent.

[0069] As an optional implementation, the I-shaped radiator core structure has no straight tubes, and only has at least three third heat dissipation core tubes 3 with curved tubes. The structure is as above and will not be repeated here.

[0070] As an optional implementation, the I-shaped radiator core structure has no straight tubes and only has at least three third heat dissipation core tubes 3 with curved tubes, which can also be evenly distributed in the space on one side of the first connecting tube 1, which will not be repeated here.

[0071] As an optional implementation, Figure 5As shown, the number of the third heat dissipation core tubes 3 is four; the four third heat dissipation core tubes 3 include four third heat dissipation core tubes 3 with bent tubes, and the bent tubes of two third heat dissipation core tubes 3 are right-angle bent tubes and are symmetrically arranged on the outward side. In this embodiment, in order to make the third heat dissipation core tubes 3 with bent tubes have efficient heat dissipation effect, the four third heat dissipation core tubes 3 between the first connecting tube 1 and the second connecting tube 2 are arranged side by side and symmetrically on both sides of the plane formed by the axis of the first connecting tube 1 and the second connecting tube 2. In addition, the right angle portion of the third heat dissipation core tube 3 with right-angle bent tubes has a smooth chamfer.

[0072] As an optional implementation, the wall thickness of the third heat dissipation core tube 3 is less than the wall thickness of the first connecting tube 1 or the second connecting tube 2. In this embodiment, the thin wall of the third heat dissipation core tube 3 can save production materials, and is more conducive to the third heat dissipation core tube 3 to quickly and efficiently conduct and diffuse the heat of the hot water circulating inside the third heat dissipation core tube 3 to the outside.

[0073] As an optional embodiment, the material of the integrally cast I-shaped structure is iron or iron alloy. The I-shaped radiator core structure of the utility model can be integrally formed by using molten iron by a casting process, replacing the current cast aluminum and cast aluminum alloy radiators.

The shell making process is completed after a series of operations such as hanging sand, dipping slurry, air drying and supporting wax are performed on the assembled wax mold. After the manufactured shell is roasted, the shell is post-processed, such as correcting, shot blasting, sand blasting and pickling the roasted shell, and after chemical analysis (spectroscopy), it is reserved for casting. The molten iron is poured into the placed mold area for casting, and after the casting is completed and condensed, the residue is cleaned, and then heat treatment is performed, and then the pre-machining treatment of shell shaking, gate cutting and gate grinding is performed, as well as post-processing of sand blasting, shot blasting, correction and pickling is performed.
