Description

Technical Field

[0001] The utility model belongs to the technical field of radiators and relates to a radiator. Background Art

[0002] At present, general radiators, as a heating structural device, are mainly used in cold seasons and cold regions for heating and warming. Previously, cast iron was often used as the chip of the radiator, and the casting process was usually adopted for production. Generally, it has a large thickness, poor heat dissipation performance, large structural dimensions, and heavy weight, resulting in inconvenient production, transportation, and assembly, and high costs for production, transportation, and assembly. In addition, many current radiators also use steel materials to make the radiator chips, reducing the thickness of the chip structure. However, the radiators made of steel materials often adopt the welding process during production. The connection at the welding part is rough, the inner wall is rough, and the outer wall often requires secondary processing. The complex production leads to high costs and affects the production efficiency. In addition, currently, alloy heat dissipation fin structures that are separately die-cast are mostly welded on the outer side of the radiator core structure. The welding process is complex and the welding production efficiency is low. Moreover, the heat dissipation efficiency of the heat dissipation fin structure outside the current radiator core structure is difficult to meet the requirements, resulting in poor heating effects.

[0048] To further elaborate on the technical means and effects adopted by the present utility model to achieve the intended utility model purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation manners, structures, features and their effects proposed according to the present utility model as follows.

[0049] The present utility model provides a radiator, as Figures 1 to 9As shown in the figure, the radiator includes: a radiator core structure 1 made of I-shaped metal material formed by integral casting, heat dissipation fins 2 arranged on the outer side of the radiator core structure, a stud 3 connecting the radiator core structure, and a plug 4 blocking the radiator core structure; a through accommodating cavity 5 is provided in the radiator core structure 1; the heat dissipation fins 2 and the radiator core structure 1 are integrally formed by die casting; it includes: a first heat dissipation fin 21 with a corrugated surface structure whose vertical plane extends in the front-rear direction, and the first heat dissipation fin 21 is connected to the radiator core structure 1; a plurality of second heat dissipation fins 22 extending along the axis direction of the accommodating cavity 5, and the second heat dissipation fins 22 are connected to the first heat dissipation fin 21 and are perpendicular or obliquely connected; a plurality of second heat dissipation fins 22 facing forward and the first heat dissipation fin 21 form a first heat dissipation channel 81; the first heat dissipation fin 21 and the second heat dissipation fin 22 enclose an unclosed heat dissipation cavity 6. In the present invention, both side surfaces of the first heat dissipation fin 21 have a corrugated surface structure, and the height of the corrugations on the corrugated surface structure is less than the minimum height of the second heat dissipation fin 22 on the corrugated surface structure. The convex corrugated surface structure of the corrugated surface structure is coated with a copper film layer, and the corrugated structure and the copper film layer (not shown in the figure) can further increase the heat dissipation area and heat dissipation performance of the first heat dissipation fin 21 in the heat dissipation cavity 6, enhance the heat dissipation efficiency, and improve the heat dissipation effect.

[0050] As an alternative embodiment, the metal material of the radiator core structure 1 includes one or more of gray iron, ductile iron, steel, and copper. For example, the inner core structure of the metal material of the radiator core structure 1 made of I-shaped metal material formed by integral casting is not limited to the metal inner core of one or more materials among gray iron, ductile iron, steel, and copper.

[0051] As an alternative embodiment, the corrugated surface structure of the first heat dissipation fin 21 can be replaced by rectangular blocks protruding along the axis direction of the stud 3.

[0052] As an alternative embodiment, the width of the second heat dissipation fin 22 located on the front side in the direction of the stud 3 is greater than the width of the second heat dissipation fin 22 located on the rear side in the direction of the stud 3.

[0053] In the present invention, as Figure 8 and Figure 9As shown in the figure, the width of the second heat dissipation fin 22 on the front side is smaller than the width of the radiator core structure 1 in the axial direction of the stud 3. The second heat dissipation fin 22 on the front side is located at the middle position in the front part of the heat dissipation fin 2, and the second heat dissipation fin 22 on the rear side is located at the middle position in the rear part of the heat dissipation fin 2. Among them, the width of the second heat dissipation fin 22 on the front side in the axial direction of the stud 3 is slightly smaller than the width of the radiator core structure 1 in the axial direction of the stud 3, and there is a certain distance between the second heat dissipation fin 22 on the front side and the second heat dissipation fin 22 on the front side of another adjacent radiator core structure 1. The width of the second heat dissipation fin 22 on the rear side in the axial direction of the stud 3 is slightly larger than the width of the radiator core structure 1 in the axial direction of the stud 3, and the second heat dissipation fin 22 on the rear side overlaps with the second heat dissipation fin 22 on the rear side of another adjacent radiator core structure 1 to ensure that the second heat dissipation fin 22 on the rear side is a closed structure. The sequentially connected radiators are sequentially connected in the rear side direction, which avoids the heat dissipated in the heat dissipation cavity 6 from being conducted in the direction of the rear-side leaning objects such as walls and seats, avoiding damage to the above-mentioned leaning objects, further ensuring that the heat in the heat dissipation cavity 6 can be efficiently conducted in the direction of the channel formed by the front spacing to the area to be heated, improving the performance of directional heat dissipation, enhancing the heat dissipation efficiency, reducing the heat loss during the heating process, and enhancing the heating performance of the radiator.

[0054] As another optional implementation manner, in the present utility model, as Figure 2 and Figure 7 shown, the width of the second heat dissipation fin 22 on the foremost side is larger than the width of the second heat dissipation fin 22 on the rearmost side. Such a setting can ensure that the heat in the heat dissipation cavity 6 can be transmitted forward through the gaps between the second heat dissipation fins 22 on the foremost side, so as to further improve the heat dissipation efficiency of the radiator and enhance the experience of the high-efficiency heat dissipation efficiency of the radiator.

[0055] As an optional implementation manner, the middle part of the accommodation cavity 5 of the I-shaped radiator core structure 1 includes at least one through cavity in the vertical direction. For example, when the accommodation cavity 5 includes a through cavity extending up and down, the shape of the integrally cast I-shaped radiator core structure 1 made of iron material is in the shape of "I". When the accommodation cavity 5 includes two through cavities extending up and down, the shape of the integrally cast I-shaped radiator core structure 1 made of iron material is in the shape of. And so on, when the above-mentioned accommodation cavity 5 includes three or more through cavities extending up and down, it will not be elaborated here. The multiple through cavities extending up and down included in the accommodation cavity 5 can, on the one hand, expand the heat dissipation area of the accommodation cavity 5 in the integrally cast I-shaped radiator core structure 1 made of iron material; on the other hand, it can improve the throughness of the accommodation cavity 5 in the through state, enhance the mutual convection of the heat dissipation medium in the accommodation cavity 5, and improve the heat dissipation efficiency of the radiator.

[0056] As an alternative embodiment, the heat dissipation fins 2 further include a wrapping layer heat dissipation fin 20 wrapped around the outer surface of the radiator core structure 1. The wrapping layer heat dissipation fin, as a die-casting layer structure on the outer surface of the radiator core structure 1, wraps around the entire outer surface of the radiator core structure 1. The thickness of the wrapping layer heat dissipation fin 20 can generally be 0.5 - 3 cm. In the present utility model, by tightly wrapping the wrapping layer heat dissipation fin 20 around the outer surface of the radiator core structure 1, on the one hand, it protects the outer surface of the radiator core structure 1 from being corroded during use; on the other hand, it improves the heat conduction performance of the radiator core structure 1 through the wrapping layer heat dissipation fin 20 and enhances the heat dissipation efficiency of the radiator.

[0057] As an alternative embodiment, the second heat dissipation fins 22 include a plurality of vertical heat dissipation fins 221 that are parallel in the vertical direction and extend along the axis direction of the stud 3; and a plurality of horizontal heat dissipation fins 222 that are spaced apart in the vertical direction and horizontally parallel to both sides of the first heat dissipation fins 21; the height of the horizontal heat dissipation fins 222 along the axis direction of the stud 3 is less than the height of the vertical heat dissipation fins 221 along the axis direction of the stud 3.

[0058] In the present utility model, a plurality of vertical heat dissipation fins 221 form a plurality of heat dissipation channels in the vertical direction or along the axis direction of the stud 3. Similarly, a plurality of horizontal heat dissipation fins 222 form a plurality of heat dissipation channels in the horizontal direction or along the front-rear direction of the radiator core structure 1. By setting the height of the horizontal heat dissipation fins 222 along the axis direction of the stud 3 to be less than the height of the vertical heat dissipation fins 221 along the axis direction of the stud 3, the present utility model enables the heat dissipated by the plurality of vertical heat dissipation fins 221 and the horizontal heat dissipation fins 222 to flow in the through heat dissipation cavity 6 and output forward along the spacing between the second heat dissipation fins 22 in the front, improving the heat transfer efficiency in the heat dissipation cavity 6 and enhancing the heating performance of the radiator.

[0059] As an alternative embodiment, the last vertical heat dissipation fin 221 on the above-mentioned side is provided with a fourth heat dissipation channel 84 (such as Figure 4 ) at the neck near the top, and this fourth heat dissipation channel 84 can also communicate the heat dissipation cavity 6 with the outside, enabling the heat in the heat dissipation cavity 6 to be quickly transferred to the outside of the radiator.

[0060] As an alternative embodiment, the second heat dissipation fins 22 further include a first upper channel heat dissipation fin 2211 provided at the top of the vertical heat dissipation fins 221 and extending forward and upward to the front side of the radiator.

[0061] In the present utility model, the first upper channel heat dissipation fin 2211 enables the heat in the upper part of the heat dissipation cavity 6 to be quickly transferred and output to the outside through the first upper channel heat dissipation fin 2211.

[0062] As an alternative embodiment, the first upper-channel heat dissipation fin 2211 includes a first flat heat dissipation fin 2211a arranged obliquely upward or a first curved-panel heat dissipation fin 2211b arranged obliquely.

[0063] In the present utility model, the first upper-channel heat dissipation fin 2211 may include a first flat heat dissipation fin 2211a. As Figure 8 shown, as an alternative embodiment, in addition to the vertical heat dissipation fins 221 and the horizontal heat dissipation fins 222, a first flat heat dissipation fin 2211a may be additionally provided on the corrugated surface structure between the second heat dissipation fins 22 at the rear side and the second heat dissipation fins 22 at the front side, and the height of the first flat heat dissipation fin 2211a located within the vertical heat dissipation fins 221 and the horizontal heat dissipation fins 222 is set to be not higher than the height of the vertical heat dissipation fins 221, so as to facilitate the flow and transmission of the heat in the heat dissipation cavity 6 between the second heat dissipation fins 22 at the rear side and the second heat dissipation fins 22 at the front side.

[0064] As an alternative embodiment, the second heat dissipation fin 22 further includes a second lower-channel heat dissipation fin 2212 provided at the bottom end of the vertical heat dissipation fin 221 and extending downward and forward to the front side of the radiator. In the embodiment of the present utility model, the second lower-channel heat dissipation fin 2212 may be symmetrically arranged up and down with the first upper-channel heat dissipation fin 2211, or may be asymmetrically arranged, which is not limited herein. By providing the second lower-channel heat dissipation fin 2212, the heat in the lower part of the heat dissipation cavity 6 can be quickly transferred outwards through the second lower-channel heat dissipation fin 2212.

[0065] As an alternative embodiment, the second lower-channel heat dissipation fin 2212 includes a second flat heat dissipation fin 2212c arranged obliquely downward or a second curved-panel heat dissipation fin 2212d arranged obliquely. In the embodiment of the present utility model, through the first upper-channel heat dissipation fin 2211, the vertical heat dissipation fin 221 and the second lower-channel heat dissipation fin 2212, the first heat dissipation channel 81 located above and facing forward and the heat dissipation channel located below can be communicated, further promoting the heat in the heat dissipation cavity 6 to be efficiently dissipated outwards through the vertically communicated first heat dissipation channel 81, and improving the heating performance of the radiator.

[0066] As an alternative embodiment, as Figure 8 and Figure 9 shown, the second heat dissipation fin 22 further includes an inverted U-shaped top cover heat dissipation fin 223 provided above the I-shaped radiator core structure 1 and a fixed connection heat dissipation fin 225 arranged along the axis direction of the pair of screws 3; the fixed connection heat dissipation fin 225 is arranged between the top cover heat dissipation fin 223 and the wrapping layer heat dissipation fin 20, and both ends of the fixed connection heat dissipation fin 225 are fixedly connected to the top cover heat dissipation fin 223 and the wrapping layer heat dissipation fin 20 respectively.

[0067] In an embodiment of the present utility model, the fixedly connected heat dissipation fins 225 are in a plate-like structure and are arranged at intervals around the screw pair 3 between the outer surface of the wrapped heat dissipation fins 20 and the inner wall of the top cover heat dissipation fins 223. The fixedly connected heat dissipation fins 225 can quickly transfer the heat in the radiator core structure 1 to the heat dissipation cavity 6 efficiently. The width of the fixedly connected heat dissipation fins 225 in the axial direction of the screw pair 3 is not greater than the width of the radiator core structure 1 in the axial direction of the screw pair 3, so that the heat in the heat dissipation cavity 6 formed by the wrapped heat dissipation fins 20, the top cover heat dissipation fins 223 and the fixedly connected heat dissipation fins 225 can flow through, promoting the heat dissipation from the heat dissipation cavity 6.

[0068] As an alternative embodiment, the top cover heat dissipation fins 223 are provided with a second heat dissipation channel 82 facing upwards. In an embodiment of the present utility model, the second heat dissipation channel 82 is arranged on the top cover heat dissipation fins 223, which can promote the heat in the heat dissipation cavity 6 to be output upwards along the vertical channel and the second heat dissipation channel 82, enhancing the heat output efficiency of the heat dissipation cavity 6.

In an embodiment of the present utility model, the structure of the base heat dissipation fin 224 can be symmetrically arranged up and down with the top cover heat dissipation fin 223, or asymmetrically arranged, which is not limited herein. In addition, a third heat dissipation channel 83 is opened on the front side of the base heat dissipation fin 224. On the one hand, it can promote the heat transfer of the heat in the space surrounded by the base heat dissipation fin 224 in the heat dissipation cavity 6 to the outside; on the other hand, it can enable the heat in the heat dissipation cavity 6 between the second heat dissipation fins 22 at the rear side and the second heat dissipation fins 22 at the front side to be output forward through the third heat dissipation channel 83 on the base heat dissipation fin 224.

[0070] In addition, support legs 2241 are further provided at the bottom end of the base heat dissipation fin 224. One support leg 2241 is arranged at the lower part of the second heat dissipation fin 22 at the rear side, and the other support leg 2241 is arranged at the front position of the bottom of the base heat dissipation fin 224. The two support legs 2241 are arranged in a spread shape for support and external heat dissipation, which will not be elaborated here.

[0071] As an alternative embodiment, on the second heat dissipation fin 22 at the front side, a fourth heat dissipation channel is opened at the middle position of the heat dissipation cavity 6 formed by two adjacent transverse heat dissipation fins 222. The fourth heat dissipation channels are arranged in sequence in the up and down direction on the second heat dissipation fin 22 at the front side, which can further output the high-temperature heat in the heat dissipation cavity 6 forward through the fourth heat dissipation channels.

[0072] As an alternative embodiment, when the accommodation cavity 5 has a plurality of communicating cavities in the vertical direction, the above Figures 1 to 9When there is a single connected cavity, the structural form is extended and / or expanded in the front-back direction.

[0074] In the embodiment of the present utility model, the material of the heat dissipation fins 2 is aluminum material. In addition to reducing the weight of the radiator, it can also improve the heat transfer efficiency of the I-shaped radiator core structure 1 to the outside. In the present utility model, the radiator composed of the external cast aluminum material heat dissipation fins 2 adopts the wax mold precision casting process and the metal mold die-casting process, realizing that the I-shaped radiator core structure 1 integrally cast from iron material is used as the inner core structure of the corrosion-resistant radiator; the precision casting process of aluminum die-casting is adopted for the outside of the radiator core structure 1, so that the aluminum material is laminated on the surface of the I-shaped iron material radiator core structure 1 integrally cast. By using corrosion-resistant cast iron material for the inner core of the radiator and casting high-strength aluminum (or aluminum alloy) material fins on the outside for heat dissipation, it combines the structural and heat dissipation advantages of cast iron radiators, cast aluminum radiators, and steel-aluminum radiators. The structure of the present utility model can be thinner and lighter, the external structure form is more beautiful, the heat dissipation amount is large, and the service life is long, and it can be applicable to the requirements of poor heating water quality and high heat dissipation performance requirements of heating buildings.

[0075] Furthermore, in order to reduce costs, the material of the heat dissipation fins 2 can be changed from aluminum material to aluminum-magnesium alloy material to further reduce the material cost of radiator production.

[0076] As an alternative implementation, a protective coating is further included on the outer surface of the heat dissipation fins 2. When producing and manufacturing the radiator core structure of the present utility model, first, the openings of the I-shaped radiator core structure 1 are blocked, and the mold structure designed according to the external heat dissipation fins of the radiator core structure 1 is placed in the die-casting mold. After the position of the radiator core structure 1 in the die-casting mold is placed well, the molten aluminum liquid or aluminum-magnesium alloy solution is injected into the mold structure, and it is adjusted to a suitable temperature and die-cast by a stamping machine to press the aluminum or aluminum-magnesium alloy material into heat dissipation fins and wrap or fix them on the outer surface of the radiator core structure 1. After cooling down, demolding treatment is carried out to obtain the manufactured radiator. Finally, the heat dissipation fins 2 are put into storage. In addition, the outer surface of the heat dissipation fins 2 can be coated according to the use environment, such as spraying or brushing protective paint or protective resin and other materials to protect the outer surface of the radiator and extend the service life.
