Description

Technical Field

[0001] This utility model relates to the field of aluminum pot technology, specifically to a high thermal conductivity aluminum pot with a composite bottom structure. Background Technology

[0002] In the field of modern kitchen utensils, aluminum pots have become a common cooking utensil in many homes and restaurants due to their excellent properties such as light weight, durability, rapid heating, uniform heat conduction and corrosion resistance. Existing aluminum pots mostly adopt a composite bottom and outer shell structure to ensure heat retention.

[0003] A search revealed that patent CN221730284U discloses a double-layered aluminum pot. While the vacuum gaps in the side of this device provide insulation during heating and heat preservation during cooling, resulting in rapid heating and good heat retention, this vacuum-based insulation design, while enhancing heat retention to some extent, inevitably negatively impacts the thermal conductivity of the aluminum pot. The presence of the vacuum layer reduces heat transfer efficiency, leading to longer heating times during cooking. This not only reduces cooking efficiency but also wastes a significant amount of energy, failing to meet users' demands for efficient and energy-saving cooking. Therefore, there is an urgent need to improve the existing aluminum pot structure to balance the trade-off between heat retention and thermal conductivity. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a high thermal conductivity aluminum pot with a composite bottom structure, which solves the problems mentioned in the background art.

[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0006] A high thermal conductivity aluminum pot with a composite bottom structure includes a composite bottom body, an aluminum pot body is sleeved inside the composite bottom body, and a pot lid is provided on the aluminum pot body.

[0007] The bottom end face of the composite base body is fixedly installed with heat-conducting fins, and the side end face of the composite base body is embedded with a filling pipe.

[0008] The inner wall bottom surface of the composite bottom body is provided with a first wavy groove, and the bottom surface of the aluminum pot body is provided with a second wavy groove.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, a handle and a locking block are installed on the outer surface of the composite bottom body, and a locking bracket is installed on the pot lid, the locking bracket being limited by the locking block.

[0011] The beneficial effects of adopting the above-mentioned further solutions are:

[0012] The handle provides a grip for the user, making it easy to hold the aluminum pot; the locking block and the locking bracket work together to ensure that the lid can be firmly installed on the aluminum pot body, preventing the lid from accidentally falling off during cooking and ensuring the safety of the cooking process.

[0013] Furthermore, there are a total of several heat-conducting fins, which are connected by heat-conducting blocks, and flow channels are provided between the heat-conducting fins.

[0014] The beneficial effects of adopting the above-mentioned further solutions are:

[0015] Multiple heat-conducting fins are connected by heat-conducting blocks to form an integral structure, which greatly increases the contact area between the composite bottom body and the heat source. This allows for rapid absorption of heat and conduction to the aluminum pot body, significantly improving the heat conduction efficiency of the aluminum pot. The presence of flow channels can promote the flow of air or other media between the heat-conducting fins, accelerate heat transfer, further enhance heat conduction performance, and also help avoid local overheating and extend the service life of the aluminum pot.

[0016] Furthermore, the filling tube is connected to the composite base body, and a sealing cap is installed on the filling tube by threads.

[0017] The beneficial effects of adopting the above-mentioned further solutions are:

[0018] The design of the filling pipe and sealing cap allows users to easily add heat-conducting oil to the composite base body according to their actual needs. The heat-conducting oil has excellent thermal conductivity; once filled into the composite base body, it can fill any tiny gaps between the composite base body and the aluminum pot body, eliminating thermal resistance and allowing for smoother heat transfer, further improving the heat conduction effect of the aluminum pot. Simultaneously, the sealing cap, with its threaded connection, ensures a tight connection, preventing heat-conducting oil leakage and ensuring safety and stability during use.

[0019] Furthermore, the inner wall of the composite bottom body is equipped with guide posts, and the outer surface of the aluminum pot body is provided with guide grooves. The aluminum pot body is sleeved on the guide posts of the composite bottom body through the guide grooves.

[0020] The beneficial effects of adopting the above-mentioned further solutions are:

[0021] The combination of the guide post and the guide groove provides positioning and guidance for the aluminum pot body to be installed into the composite base body, making the installation process more convenient and reducing installation difficulty and time. This structural design also ensures that the relative position between the aluminum pot body and the composite base body is fixed, ensuring that the heat conduction performance of the composite base body can be stably and efficiently transferred to the aluminum pot body, avoiding uneven heat conduction caused by installation deviation.

[0022] Furthermore, the aluminum pot body is fitted with the first wavy groove of the composite bottom body through the second wavy groove.

[0023] The beneficial effects of adopting the above-mentioned further solutions are:

[0024] The first wave-shaped groove fits into the second wave-shaped groove. Compared to flat contact, this wave-shaped fit greatly increases the contact area between the composite bottom body and the aluminum pot body, effectively reducing the thermal resistance between the two. More contact points allow heat to be conducted more efficiently between the two, thereby improving the overall thermal conductivity of the aluminum pot, enabling the aluminum pot body to be heated faster and more evenly, improving cooking efficiency and food cooking quality.

[0025] Furthermore, a limiting spring is installed on the inner wall of the composite bottom body, and an installation spring is installed on the outer surface of the aluminum pot body, with the installation spring sleeved inside the limiting spring.

[0026] The beneficial effects of adopting the above-mentioned further solutions are:

[0027] The combination of the limiting spring and the mounting spring enables a detachable connection between the aluminum pot body and the composite bottom body. When either the aluminum pot body or the composite bottom body is damaged, the user does not need to replace the entire pot; only the damaged part needs to be disassembled for repair or replacement, reducing operating costs. Simultaneously, this flexible connection provides cushioning and tightening force after installation, ensuring a stable connection between the aluminum pot body and the composite bottom body during use, preventing easy loosening and ensuring normal operation of the aluminum pot. Furthermore, sealing gaskets can be attached to both the limiting spring and the mounting spring, ensuring a tight seal after connection.

[0028] This invention provides a high thermal conductivity aluminum pot with a composite bottom structure. It has the following beneficial effects:

[0029] This invention improves the heat conduction efficiency of aluminum pots through various design features. The heat-conducting fins significantly increase the contact area with the heat source, the flow channels promote heat transfer, and the heat-conducting block connects multiple fins into a single unit, enabling rapid and even heat transfer to the aluminum pot body. Furthermore, the composite bottom body and the aluminum pot body are bonded together through the first and second wavy grooves, further increasing the contact area, reducing thermal resistance, and achieving highly efficient heat conduction. This allows the aluminum pot body to heat up faster and more evenly, greatly improving cooking efficiency and food quality.

[0030] The locking block and locking bracket work together to ensure the lid is securely installed during cooking, preventing accidental detachment and ensuring safety. The design of the filling tube and sealing cap not only facilitates the addition of heat transfer oil to improve heat conduction, but also effectively prevents oil leakage, ensuring safety and stability during use.

[0031] The guide post and guide groove provide positioning and guidance for the installation of the aluminum pot body. The detachable connection design of the limiting spring and the mounting spring allows users to easily repair or replace any damaged component of the aluminum pot body or composite bottom body without replacing the entire unit, effectively reducing operating costs.

[0032] The presence of flow channels promotes the flow of air or other media between the heat-conducting fins, helping to avoid localized overheating, reducing damage to the pot material caused by high temperatures, and extending the lifespan of the aluminum pot. Furthermore, the composite bottom structure disperses heat and pressure, reducing the risk of pot deformation and further improving the durability of the aluminum pot. Attached Figure Description

Detailed Implementation

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] Please see Figures 1 to 4 As shown, the embodiments provided by this utility model are as follows:

[0043] Example 1

[0044] A high thermal conductivity aluminum pot with a composite bottom structure includes a composite bottom body 1, an aluminum pot body 5 is sleeved inside the composite bottom body 1, and a pot lid 3 is provided on the aluminum pot body 5.

[0045] A heat-conducting fin 4 is fixedly installed on the bottom end face of the composite base body 1, and a filling pipe 2 is embedded in the side end face of the composite base body 1.

[0046] The bottom surface of the inner wall of the composite bottom body 1 is provided with a first wave-shaped groove 104, and the bottom surface of the aluminum pot body 5 is provided with a second wave-shaped groove 502.

[0047] The outer surface of the composite base body 1 is equipped with a handle 101 and a locking block 102. The lid 3 is equipped with a locking bracket 301. The locking bracket 301 is limited by the locking block 102. The handle 101 provides a gripping part for the user, making it convenient to hold the aluminum pot. The cooperation between the locking block 102 and the locking bracket 301 allows the lid 3 to be firmly installed on the aluminum pot body 5, preventing the lid 3 from accidentally falling off during cooking and ensuring the safety of the cooking process.

[0048] There are several heat-conducting fins 4, which are connected by heat-conducting blocks 402. There are flow channels 401 between the heat-conducting fins 4. The multiple heat-conducting fins 4 are connected by heat-conducting blocks 402 to form an integral structure, which greatly increases the contact area between the composite bottom body 1 and the heat source. It can quickly absorb heat and conduct it to the aluminum pot body 5, significantly improving the heat conduction efficiency of the aluminum pot. The presence of flow channels 401 can promote the flow of air or other media between the heat-conducting fins 4, accelerate the heat transfer, further enhance the heat conduction performance, and at the same time help to avoid local overheating and extend the service life of the aluminum pot.

[0049] The aluminum pot body 5 is attached to the first wavy groove 104 of the composite bottom body 1 through the second wavy groove 502. The first wavy groove 104 is attached to the second wavy groove 502. Compared with flat contact, this wavy attachment method greatly increases the contact area between the composite bottom body 1 and the aluminum pot body 5, effectively reducing the thermal resistance between the two. More contact points allow heat to be conducted more efficiently between the two, thereby improving the thermal conductivity of the entire aluminum pot, enabling the aluminum pot body 5 to be heated faster and more evenly, improving cooking efficiency and food cooking quality.

[0050] Example 2

[0051] To avoid the gap between the composite bottom and the aluminum pot affecting heat conduction and to increase the heat retention effect, for example, such as Figures 1 to 4 As shown, this utility model also includes:

[0052] The filling pipe 2 is connected to the composite bottom body 1. A sealing cap 201 is threaded onto the filling pipe 2. The design of the filling pipe 2 and the sealing cap 201 allows users to easily add heat-conducting oil into the composite bottom body 1 according to actual needs. The heat-conducting oil has excellent thermal conductivity. After being filled into the composite bottom body 1, it can fill any tiny gaps that may exist between the composite bottom body 1 and the aluminum pot body 5, eliminating thermal resistance and making heat transfer smoother, further improving the heat conduction effect of the aluminum pot. At the same time, the sealing cap 201 is threaded to ensure a tight connection, prevent heat-conducting oil leakage, and ensure safety and stability in use.

[0053] Example 3

[0054] To allow for easy installation and removal of the composite bottom from the aluminum pot, avoiding the need for complete replacement after damage to a single component, for example, such as... Figures 1 to 4 As shown, this utility model also includes:

[0055] The inner wall of the composite base body 1 is equipped with guide posts 103, and the outer surface of the aluminum pot body 5 is provided with guide grooves 501. The aluminum pot body 5 is sleeved on the guide posts 103 of the composite base body 1 through the guide grooves 501. The cooperation between the guide posts 103 and the guide grooves 501 provides positioning and guidance for the installation of the aluminum pot body 5 into the composite base body 1, making the installation process more convenient and reducing the installation difficulty and time. This structural design can also ensure that the relative position between the aluminum pot body 5 and the composite base body 1 is fixed, ensuring that the heat conduction performance of the composite base body 1 can be stably and efficiently transferred to the aluminum pot body 5, avoiding uneven heat conduction caused by installation deviation.

[0056] The inner wall of the composite base body 1 is equipped with a limiting spring 105, and the outer surface of the aluminum pot body 5 is equipped with an installation spring 503. The installation spring 503 is sleeved within the limiting spring 105. The cooperation between the limiting spring 105 and the installation spring 503 realizes a detachable connection between the aluminum pot body 5 and the composite base body 1. When one part of the aluminum pot body 5 or the composite base body 1 is damaged, the user does not need to replace the whole thing, but only needs to disassemble the damaged part for individual repair or replacement, reducing the cost of use. At the same time, this elastic connection method can provide a certain buffer and fastening force after installation, ensuring that the aluminum pot body 5 and the composite base body 1 remain stably connected during use and will not easily loosen, ensuring the normal use of the aluminum pot. Moreover, sealing gaskets can be attached to both the limiting spring 105 and the installation spring 503 to ensure the sealing of the connection after installation. The sealing gaskets can be ceramic fiber sealing gaskets.

[0057] Working principle:

[0058] Positioning of the composite bottom body 1 and the aluminum pot body 5

[0059] The guide post 103 on the inner wall of the composite bottom body 1 is inserted into the guide groove 501 on the outer surface of the aluminum pot body 5 to achieve the initial positioning and guiding installation of the two.

[0060] The first wavy groove 104 on the inner wall of the composite bottom body 1 fits into the second wavy groove 502 on the bottom surface of the aluminum pot body 5. The wavy structure increases the contact area and reduces thermal resistance.

[0061] The limiting spring 105 on the inner wall of the composite bottom body 1 locks the mounting spring 503 on the outer surface of the aluminum pot body 5, forming an elastic and detachable connection, ensuring structural stability after installation, and facilitating maintenance and replacement of parts.

[0062] Fixing the lid 3 to the composite base body 1

[0063] The snap-fit ​​bracket 301 on the lid 3 is fastened to the snap-fit ​​block 102 on the outer surface of the composite bottom body 1, thereby limiting and fixing the lid 3 and preventing it from falling off during cooking.

[0064] Heat absorption and conduction

[0065] The heat-conducting fins 4 at the bottom of the composite base body 1 are connected as a whole by the heat-conducting block 402, which greatly increases the contact area with the heat source (such as gas stove or induction cooker) and quickly absorbs heat.

[0066] The flow channels 401 between the heat-conducting fins 4 promote the flow of air or medium, accelerate heat transfer, and avoid local overheating.

[0067] Internal thermal conductivity enhancement

[0068] Heat-conducting oil is injected into the composite bottom body 1 through the filling pipe 2 (and sealed with the sealing cap 201 after filling). The heat-conducting oil fills the gap between the composite bottom body 1 and the aluminum pot body 5, eliminates thermal resistance, improves heat conduction efficiency, and increases heat preservation capacity after heating.

[0069] The heat absorbed by the composite bottom body 1 is transferred to the aluminum pot body 5 through the heat-conducting oil and the corrugated groove bonding surface, so as to achieve uniform heat conduction.

[0070] Heating process of aluminum pot body 5

[0071] Heat is conducted from the composite bottom body 1 to the aluminum pot body 5. Due to the increased contact area caused by the wavy grooves, the bottom surface of the aluminum pot body 5 is heated quickly and evenly, improving cooking efficiency.

[0072] The combination of the flow channel 401 and the heat-conducting fins 4 promotes heat diffusion, avoids local overheating of the aluminum pot body 5, and ensures the quality of food cooking.

[0073] Sealing and Leakage Prevention

[0074] The sealing cap 201 of the filling pipe 2 is connected by threads to prevent heat transfer oil leakage; the limiting spring 105 and the mounting spring 503 can be fitted with sealing gaskets to enhance the connection sealing.

[0075] Disassembly and repairable design

[0076] When the aluminum pot body 5 or the composite bottom body 1 is damaged, the parts can be replaced individually by disassembling the limiting spring 105 and the mounting spring 503, thus reducing the cost of use.

[0077] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
