Description

Technical Field

[0001] The present application relates to residential heating devices, and more particularly to radiators, and more particularly to a copper-aluminum radiator. Background Art

[0002] With the development of industrialization worldwide, energy consumption is increasing day by day. Traditional fossil fuel resources will eventually be exhausted, and fossil fuels will also cause environmental pollution during use. In order to achieve long-term development, it is necessary to alleviate or even solve the energy and environmental crisis through the development of renewable energy, production of sustainable energy and improvement of energy efficiency. This has become a general consensus.

[0003] Among them, improving energy efficiency is an indispensable part. Increasing the existing energy utilization rate by 1% is also a very significant improvement. It can not only save the total energy consumption, but also reduce emissions and reduce pollution to the environment.

[0004] For a long time, most areas in northern my country have been heating their homes in winter. Floor heating is relatively beautiful because the pipelines are buried under the floor, and it can provide a relatively ideal heating effect with the insulation wall. However, traditional metal radiators still occupy a large market share for many reasons. For example, in small-sized houses or rooms, the installation cost of radiators is much lower, but the heating effect is almost the same as floor heating, or even better. In addition, due to thermal radiation and convection, the floor of the room with floor heating is more likely to accumulate dust and cause dust to rise, while the radiator is hung on the wall to reduce such situations. Another advantage of the radiator is that it does not sacrifice the floor height of the house, and it can be installed in rooms with waterproofing requirements. For example, radiators are widely used for heating in bathrooms and kitchens. In some southern regions, if there are conditions to install heating furnaces, fuel heating can also be used. Due to the high humidity in the south, floor heating may cause moisture on the floor and walls after the heating ends, so metal radiators will also be considered for heating in the living room that needs heating.

[0005] At present, copper-aluminum radiators occupy a considerable share of the radiator market, and their advantages lie in the following aspects:

[0006] Excellent thermal conductivity: The thermal conductivity of copper is much higher than that of aluminum, so the thermal conductivity of copper-aluminum composite heat sink is better than that of pure aluminum heat sink. This means that the heat sink can transfer heat to the surrounding environment faster, improving the heat dissipation efficiency.

[0007] High structural strength: Aluminum alloy has good mechanical properties and corrosion resistance, and can be manufactured into various complex shapes and structures through extrusion molding to enhance the structural strength of the radiator.

[0008] Light weight: Although the density of copper is greater than that of aluminum, in the copper-aluminum composite radiator, there is usually only a thin layer of copper, and most of the material is still aluminum, so the overall weight is relatively light, which is convenient for handling and installation.

[0009] Cost-effectiveness: Copper materials are relatively expensive, but through the copper-aluminum composite method, the cost can be reduced while ensuring heat dissipation performance. Copper is used for the internal heat conduction channel, while aluminum is used as the main material. This combination can balance performance and cost.

[0010] Corrosion resistance: A dense oxide film can form on the aluminum surface to protect the internal materials from further corrosion. In addition, the radiator surface is usually treated with an additional anti-corrosion coating to enhance corrosion resistance.

[0011] Easy to process and manufacture: Aluminum is easy to process into various sizes and shapes, suitable for large-scale production, which helps to reduce manufacturing costs.

[0012] Strong adaptability: Copper-aluminum radiators can be applied to a variety of different working environments and conditions, including different working media (such as water, oil, etc.) and different temperature ranges.

[0013] In summary, the copper-aluminum heat sink combines the excellent thermal conductivity of copper with the light weight, cost-effectiveness and processing convenience of aluminum. It is a high-performance and economical heat dissipation solution.

[0014] However, the structure of the copper-aluminum radiator still has certain limitations. For example, the panel is often made of pultruded aluminum profiles, which imposes many restrictions on the shape of the panel. If the panel width is large, it is necessary to either thicken the specifications, otherwise it is difficult to ensure strength; or increase the support structure to avoid panel deformation. Thickening will increase material loss, increase costs, and increase the overall weight of the radiator. Adding a support structure will increase the number of closed holes in the profile section, making it more difficult to develop and manufacture the mold. In other words, there is room for improvement in balancing the structural strength of the radiator, manufacturing costs, and processing difficulty.

[0015] In addition, the structural panels of current copper-aluminum radiators are all planar structures. When heat exchange is performed, the airflow presents a laminar state on the panel surface, the heat exchange contact effect is relatively poor, and the heat exchange is insufficient. There is also room for improvement.

[0016] In addition, the radiator hopes to achieve a lightweight design while ensuring the heat dissipation effect. However, a significant defect of a thin and light structure is that it is difficult to perform thermal processing, such as welding or thermal assembly, and it is easy to deform or damage during the processing. Utility Model Content

At the same time, the panel is set to a folding plate structure to improve the strength of the folding plate, so as to achieve a lightweight design of the panel. The folding plate structure can also allow the airflow to form turbulence when flowing through the panel, making the heat exchange more sufficient and improving the heat exchange efficiency, achieving multiple goals at one stroke. The folding plate structure is combined with the slot connection method of the upper buckle cover and the lower buckle cover, and can replace thermal processing or riveting with mechanical plug-in.

DETAILED DESCRIPTION

[0066] In order to more clearly illustrate the overall concept of the present application, a detailed description is given below in an illustrative manner in conjunction with the accompanying drawings.

[0067] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present application. However, the present application can also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific implementation methods disclosed below.

[0068] In the description of the present application, it should be understood that the terms "upper", "lower", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In the present application, unless otherwise clearly specified and limited, a first feature being "upper" or "lower" than a second feature may be that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

[0069] In this application, unless otherwise clearly specified and limited, the terms "installation", "connection" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. However, if it is indicated as a direct connection, it means that the two connected bodies are not connected through a transition structure, but are only connected to form a whole through a connecting structure. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0070] In this application, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0071] Combination Figures 1 to 4 , depicting a copper-aluminum heat sink, combined with Figure 7 , including a copper tube group 100, including an upper transverse tube 101, a lower transverse tube 102, and a group of vertical tubes 103 connected between the upper transverse tube 101 and the lower transverse tube 102; Figure 7 Ignoring other structures, the two ends of the vertical pipe 103 are respectively connected to the upper horizontal pipe 101 and the lower horizontal pipe 102 to form a channel for the heat exchange medium, and the heat exchange medium can be clean water or clean oil. The radiator is connected through the pipeline, and the heat exchange medium flows in the copper tube group, dissipating the heat carried by the heat exchange medium to the outside of the radiator. This heat exchange process realizes the heating function.

[0072] On the basis of the copper tube group 100, an aluminum profile 200 corresponding to each vertical tube 103 is configured, combined with Figure 8 and Fig. 9 , the aluminum profile 200 includes a central tube 201, referring to Figure 3 The inner wall of the central tube 201 forms an interference fit or transition fit with the outer wall of the vertical tube 103, and a plurality of wings 202 extend outward from the outer wall of the central tube 201; a pair of panels 300 formed separately from the aluminum profile 200 are arranged on both sides of the aluminum profile 200, and part of the wings 2021 of each aluminum profile abuts against the inner side of the panel 300. In the figure, part of the wings 2022 does not directly contact the panel 300, as a structure to increase the heat dissipation contact surface. The panel 300 is a corrugated bent plate.

[0073] The existing copper-aluminum radiator has the panel formed at the end of the aluminum profile wing, that is, a panel is extended from the end of two or more wings. This will inevitably form a hole structure in the cross-section of the aluminum profile, which means that the pultrusion mold needs to form a corresponding core structure, which increases the difficulty of mold development and manufacturing. Separately molding the panel and the aluminum profile can make the wings an open structure instead of a closed structure, eliminating the need for core pulling and reducing the difficulty of the pultrusion process.

[0074] At the same time, separating the panel and the aluminum profile will bring additional benefits and may also better control costs. The price of aluminum profiles pultruded by customized molds is higher than that of aluminum plates. Making the panel part independently can reduce the proportion of aluminum profiles, thereby reducing costs overall. At the same time, due to the requirements of the molding process, pultrusion molding cannot make the panel part too thin, otherwise the product quality cannot be ensured. However, an independent panel can make the size thinner, further reducing costs while achieving overall lightweighting of the radiator.

[0075] The lightweight panel combined with the bending structure can increase the overall strength of the panel through bending. At the same time, due to the structure of the bending surface, turbulence is continuously formed when the airflow flows on the surface of the panel to achieve heat exchange. This turbulence is conducive to full contact between the airflow and the panel, improving the efficiency of heat exchange, and thus improving the overall heating efficiency of the radiator.

[0076] In addition, the bent panel structure also increases the airflow contact area, that is, the heat dissipation area of ​​the radiator. The panel is separated from the aluminum profile, which has the advantage of removing the gap between adjacent aluminum profiles, which can reduce the dust accumulation inside the radiator. Figure 3 and Figure 4 The two ends of the bent panels can be set to fit together to seal the inside of the radiator. This reduces dust accumulation, and also encapsulates aluminum profiles inside the two panels to achieve an aesthetically pleasing industrial design. From the outside, the radiator is a structure of a row of diamond-shaped columns connected together.

[0077] In other words, by independently molding the panel from the aluminum profile, many unexpected beneficial effects can be obtained. The current market mainstream is still to form each sub-panel structure during the aluminum profile molding process, and then assemble and splice the panels. No radiator with an obvious folded panel structure has been found.

[0078] In addition, combined Figures 10 to 13 , providing an embodiment of a radiator that reduces welding and drilling connection methods. The radiator includes a lower buckle cover 400 that covers and supports the lower cross tube 102, including a bottom plate, a lower support member 403 disposed between the bottom plate and the lower cross tube 102, and a pair of lower vertical plates extending from the edges of both sides of the bottom plate. The lower vertical plates and the bottom plate together form a groove structure 401, which is the main body of the lower buckle cover. The lower vertical plates are provided with a pair of slots 402, and the position and size of the slots 402 correspond to the bending shape of the panel 300, so that a pair of panels 300 can be plugged into a pair of lower vertical plates; that is, Figures 2 to 4In the lower part of the structure shown, the panel is inserted into the slot formed by the lower vertical plate, partly protruding from the outside of the lower vertical plate and partly recessed into the interior of the lower vertical plate, forming a stable and reliable fixed structure to limit the movement of the panel. The width of the slot is set to be slightly larger than the thickness of the panel. Specifically, the thickness of the panel is set to H1, the thickness of the lower vertical plate is H2, and the width of the slot is W, so that 1.1X (H2 / +H1 / )>W≥H2 / +H1 / ; Since the bent plate itself has a certain elasticity, within the above-mentioned size range, since the panel itself is supported by the aluminum profile, the bent plate will fit tightly with the slot, and the plug-in length is not less than 20mm, which will generate a certain friction force. This friction force can make the panel and the lower buckle cover relatively fixed and not easy to separate. With the assistance of other positioning structures, there is no need to use welding to reinforce them.

[0079] Similarly, the radiator also includes an upper buckle cover 500 that covers and supports the upper cross tube 101, including a top plate, an upper support member 5031 arranged between the top plate and the upper cross tube 101, and a pair of upper vertical plates extending from the edges of both sides of the bottom plate. The upper vertical plates 501 are provided with a pair of slots (roughly the same as the lower buckle cover structure), and the position and size of the slots correspond to the bending shape of the panel so that a pair of panels can be plugged into a pair of upper vertical plates.

[0080] Through the slot structure, the upper buckle cover, panel and lower buckle cover are cleverly connected, and then the various parts of the radiator are assembled into one, which can be directly plugged in without welding or drilling, and is also suitable for the design of thin panels. Thin panels are difficult to weld, and drilling holes for threaded connections or riveting will add extra steps and affect the appearance of the product. By using the elasticity of the bent plate itself to achieve plug-in fixation, a stable connection structure can be obtained.

[0081] Combination Fig.11 and Fig.12 The lower side of the lower support member 403 is connected to the bottom plate, and the lower support member 403 forms a connecting hole 4031 corresponding to the lower transverse tube for the lower transverse tube to pass through; the upper side of the upper support member 503 is connected to the top plate, and the upper support member forms an arc groove 5031 corresponding to the upper transverse tube to support the upper transverse tube.

[0082] The upper cross tube and the upper buckle cover, the lower cross tube and the lower buckle cover are reliably positioned and connected through the upper and lower supports, and the upper and lower buckle covers are then plugged into the panel. At the same time, the aluminum profile supports the inside of the panel to form a stable structure of the radiator. The overall weight of the radiator is supported by the copper tube group, and then the lower cross tube in the copper tube group is supported by a group of lower supports. When the radiator is placed, the radiator is supported by the bottom plate as a whole and then pressed on the ground. Or in the case of a suspended radiator, you can choose to suspend the end of the copper tube group. Since the radiator adopts a lightweight design as a whole, as long as the copper tube group is reliably fixed, the load on other structures is very small. During transportation, the copper tube group is also used as the lifting point or bearing point.

[0083] Through the above-mentioned various optimization schemes, in various embodiments of the present application, the panel can be designed to be lightweight and thin, and the thickness can reach 0.2mm to 0.3mm, which can meet the processing requirements of bending and punching.

[0084] Combination Figure 5 and Figure 6 The bending angle α of the panel 300 is in the range of 80° to 100°. When the bending angle is in a suitable range, the panel provides sufficient airflow contact area, which is about 1.5 times that of a flat plate, and also meets the demand for improving structural strength. In addition, it is also conducive to controlling the overall thickness of the radiator. Combined with Figure 3 , the bending angle is, for example, 90°, and a pair of panels are relatively buckled to form a column with a nearly square cross-section, which completely covers the aluminum profile and separates it into several separate units, which is quite aesthetic. The distance between the central tube or vertical tube and the panel is also relatively uniform, which can also improve the efficiency of heat dissipation. As an optimization scheme of this implementation scheme (not shown in the figure), the protruding bend of the panel can be set to form a larger fillet to form a wavy visual perception, while also making the distance between the vertical tube and the panel more uniform.

[0085] Considering the requirements for panel strength and processability, the panel is made of semi-hard alloy aluminum plate. Alloy aluminum can be used for sheet metal parts, such as 3003, 3005, 5052 and other semi-hard sheet metal bending parts.

[0086] refer to Figures 16 to 19 In the heat sink shown in the figure, the panel 310 is formed with a plurality of through holes 311, and the distance L between the through holes 311 and the bending position of the panel 310 is not less than 2 cm. As shown in the figure, the distance L is the distance from the center of the bend to the center of the through hole.

[0087] The through hole can be drilled before bending, avoiding the bending position and not affecting the bending formation. The through hole can form a new airflow path, increase the airflow inside and outside the panel, and also increase the turbulence intensity of the turbulent flow, thereby improving the heat exchange efficiency. As shown in the figure, the through hole 311 is a circular hole. In other embodiments not shown in the figure, for aesthetic considerations, the through hole can be set as a diamond hole or other shaped special-shaped hole, which can be obtained by punching.

[0088] Combination Fig.14 and Fig.15 In one embodiment, in the aluminum profile 210, the edge of the wing 213 is formed with a flat plate with a width of not less than 1 cm, and the flat plate is attached to the panel. The flat plate formed by the edge of the wing can increase the abutment support area, reliably support the panel, and make the radiator more stable as a whole. It can also be used to set a thinner panel.

[0089] The manufacturing method of the copper-aluminum radiator as described above mainly comprises the following steps:

[0090] Cut the upper horizontal pipe, lower horizontal pipe and vertical pipe;

[0091] Cut the aluminum profile, the length of the aluminum profile should be at least 50mm shorter than the vertical pipe;

[0092] The aluminum sheet is bent into a corrugated bent sheet to form a panel;

[0093] The aluminum plate is bent into a groove shape to form an upper buckle cover and a lower buckle cover. The aluminum plate is punched into an upper support member and a lower support member. The upper support member is fixedly installed in the upper buckle cover. The upper buckle cover and the lower buckle cover are opened into a pair of installation grooves corresponding to the shape of the panel bending.

[0094] The aluminum profile is matched with the vertical tube, and both ends of the vertical tube extend out by at least 25 mm;

[0095] The vertical tubes are connected in a row with the upper horizontal tube and the lower horizontal tube to form a copper tube group. During the connection process, a lower support is mounted on the lower horizontal tube, wherein the lower support is arranged at intervals with the vertical tube;

[0096] The lower horizontal tube in the copper tube group is placed together with the lower support piece into the lower buckle cover. The support piece is fixedly connected to the inner wall of the lower buckle cover. The panel fits the wing of the aluminum profile and is inserted into the installation groove opened in the lower horizontal tube. The upper buckle cover is installed so that the upper end of the panel is also inserted into the installation groove opened in the upper buckle cover. At the same time, the upper horizontal tube is supported by the upper support piece.

[0097] The copper-aluminum radiator mentioned above can be manufactured by the above method. Fig. 20 As shown, during the production of the copper tube group, a tooling structure 600 with a size and shape corresponding to the panel can be used, and the aluminum profile 200 with the vertical tube 103 inserted can be placed in the tooling structure, and the two ends can be aligned to ensure that the direction of the aluminum profile is consistent and accurate. This is also the process optimization brought by the copper-aluminum radiator structure.

[0098] In addition, when the panel needs to be opened, several through holes should be opened before the aluminum plate is bent into a wavy bent plate, avoiding the bending position. The through hole structure can be formed by stamping or multi-layer stacking drilling.

[0099] Anything not described in this application can be achieved by adopting or drawing on existing technologies.

[0100] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0101] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
