Description

Technical Field

[0001] This utility model relates to the field of double-helix cast aluminum technology, and in particular to a double-helix cast aluminum heating coil. Background Technology

[0002] Cast aluminum heating coils are electric heaters that use tubular electric heating elements as the heating body and high-quality aluminum alloy materials as the outer shell, formed by die casting. Cast aluminum heaters are generally produced using a casting process. During casting production, high-purity aluminum blocks are used, which are transformed from solid to liquid in a high-temperature furnace. The liquid is then injected into a mold with heating tubes already installed. After cooling and solidification, it is then precision-machined. For example, a double-helix cast aluminum heating coil disclosed in application number 202222135670.7 can achieve direct contact between cold water and the heating coil body, thereby improving the absorption efficiency of cold water on the surface of the heating coil body.

[0003] However, the above structure cannot effectively isolate the heat during use, thus preventing it from forming a double layer. This can easily lead to heat leakage and damage, reducing its insulation and usage efficiency. Furthermore, it cannot be easily installed and disassembled, reducing its maintenance and cleaning efficiency. Therefore, we propose a double-helix cast aluminum heating coil. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a double-helix cast aluminum heating coil that can effectively isolate the heat, thereby forming a double-layer structure that is less likely to cause damage caused by heat leakage, improving its heat insulation efficiency and usage efficiency, and enabling convenient installation and disassembly, thus improving its maintenance and cleaning efficiency.

[0005] To achieve the above objectives, a double-helix cast aluminum heating coil is provided, comprising: two mutually fitted outer arc-shaped plates, each of the two outer arc-shaped plates having an inner arc-shaped plate inside, a first spiral heating coil being disposed within the two inner arc-shaped plates, and a second spiral heating coil being fitted over the first spiral heating coil; a first connector is connected to the left side of the first spiral heating coil near the top and bottom, and the first connector extends beyond the outer arc-shaped plates; a second connector is connected to the right side of the second spiral heating coil near the top and bottom, and the second connector extends beyond the outer arc-shaped plates.

[0006] According to the aforementioned double-helix cast aluminum heating coil, the front and rear walls of the two outer arc plates are welded with butt blocks near the top and bottom, and the two butt blocks that fit together are connected by fastening screws.

[0007] According to the aforementioned double-helix cast aluminum heating coil, the outer arc plate and the inner arc plate located on the same side are both connected to fixing screws near the top and bottom via threaded holes.

[0008] According to the aforementioned double-helix cast aluminum heating coil, an outer circulation pipe is provided on the outer sleeve of the two inner arc plates, and an inner circulation pipe is connected to the inner wall of the front and rear sides of the inner arc plates. The inner circulation pipe is internally connected to the outer circulation pipe.

[0009] According to the aforementioned double-helix cast aluminum heating coil, horizontal pipes are connected to both sides of the outer circulation pipe near the top and bottom, and valves are installed on the horizontal pipes extending to the outer arc plate.

[0010] The above solution has at least one of the following beneficial effects: This technical solution, through the cooperation between the two outer arc plates, the inner arc plate, the outer circulation pipe and the inner circulation pipe, enables it to effectively isolate the structure, thereby forming a double-layer structure. This makes it less likely to cause damage caused by heat leakage, improves its heat insulation efficiency and usage efficiency, and allows for convenient installation and disassembly, thus improving its maintenance and cleaning efficiency.

[0019] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0020] Reference Figures 1 to 4 This utility model discloses a double-helix cast aluminum heating coil, comprising two mutually fitted outer arc-shaped plates 1, each containing an inner arc-shaped plate 3. A first spiral heating coil 12 is disposed within each inner arc-shaped plate 3, and a second spiral heating coil 13 is fitted over the first spiral heating coil 12. First connectors 2 are connected to the left side of the first spiral heating coil 12 near its top and bottom, extending beyond the outer arc-shaped plates 1. Second connectors 4 are connected to the right side of the second spiral heating coil 13 near its top and bottom, extending beyond the outer arc-shaped plates 1.

[0021] Two outer arc-shaped plates 1 have butt joints 7 welded to their front and rear walls near the top and bottom, respectively. Fastening screws 6 connect the two mating butt joints 7. Fixed screws 5 are connected to the outer arc-shaped plate 1 and the inner arc-shaped plate 3 on the same side near the top and bottom via threaded holes. This structure allows for effective insulation, creating a double-layer design that reduces the risk of heat leakage and improves insulation and usability. It also facilitates easy installation and disassembly, enhancing maintenance and cleaning efficiency.

[0022] Two inner arc-shaped plates 3 are fitted with outer circulation pipes 10, and inner circulation pipes 11 are connected to the inner walls of the front and rear sides of the inner arc-shaped plates 3. The inner circulation pipes 11 are connected to the interior of the outer circulation pipes 10. Horizontal pipes 8 are connected to the left and right sides of the outer circulation pipes 10 near the top and bottom, and valves 9 are installed on the horizontal pipes 8 extending to the outside of the outer arc-shaped plates 1. Through this structure, cold water can be added and discharged to achieve the purpose of auxiliary cooling.

[0023] Working Principle: In this technical solution, the two outer arc-shaped plates 1 are first fixed using the connecting block 7 and fastening screw 6. The outer circulation pipe 10 is then fitted over the two closely fitting inner arc-shaped plates 3 and connected to the inner circulation pipe 11. The inner arc-shaped plates 3 are then placed inside the two outer arc-shaped plates 1 and fixed using the fixing screw 5. This allows the first connector 2, the second connector 4, and the horizontal pipe 8 to extend beyond the outer arc-shaped plates 1, effectively isolating them and forming a double-layer structure. This prevents heat loss and reduces the risk of damage, improving insulation and efficiency. It also allows for convenient installation and disassembly, increasing maintenance and cleaning efficiency. Cold water is injected into the outer circulation pipe 10 through the upper horizontal pipe 8, filling both the outer and inner circulation pipes 10 and 11. Opening the lower valve 9 allows water to be discharged through the lower horizontal pipe 8, enabling the addition and discharge of cold water for auxiliary cooling.

[0024] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
