Description

Technical Field

[0001] This utility model relates to the field of concrete cooling technology, and in particular to a concrete hydration heat cooling device. Background Technology

[0002] The chemical reaction between cement and water in concrete produces hydration products and releases a large amount of heat; this process is called heat of hydration. In large-volume concrete, the heat of hydration increases due to the higher cement content. During concrete pouring, the internal temperature of the concrete rises rapidly due to the heat of hydration, while the external temperature remains relatively low. This temperature difference causes uneven expansion and contraction, resulting in thermal stress. When this thermal stress exceeds the tensile strength of the concrete, thermal cracks can form on the surface or inside the concrete. These cracks not only weaken the overall structural strength of the concrete but also provide pathways for the intrusion of external moisture and chemicals (such as sulfates and chloride ions), thus accelerating steel corrosion and concrete carbonation, ultimately shortening the service life of the concrete structure.

[0003] Currently, traditional cooling equipment mainly relies on water pipe circulation for refrigeration. These devices are relatively large, typically requiring numerous cables, resulting in complex wiring and cumbersome installation. Furthermore, due to the reliance on water pipe circulation systems, it is difficult to achieve precise local temperature control, which not only reduces the temperature control effect but also leads to water waste; if water pipe blockage occurs, repair costs are high. Utility Model Content

[0004] The purpose of this invention is to provide a concrete hydration heat cooling device that can effectively absorb and disperse the hydration heat of large-volume concrete during the solidification process. It does not require a complex water pipe circulation system, thus avoiding resource waste and water pipe blockage, reducing maintenance and operating costs. At the same time, the device does not require complex cable connections, is easy to carry, adapts to various construction environments, and improves the stability and durability of large-volume concrete construction.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A concrete hydration heat cooling device, comprising:

[0007] Multiple cooling components are embedded in concrete. Each cooling component includes a heat-conducting outer shell, a melting trigger shell, a cooling agent, and cooling water. The melting trigger shell is located inside the heat-conducting outer shell, the cooling agent is encapsulated within the melting trigger shell, and the cooling water fills the space between the melting trigger shell and the heat-conducting outer shell. The heat-conducting outer shell can conduct the heat released during the concrete solidification process to the melting trigger shell, causing it to melt. After melting, the melting trigger shell can release the cooling agent encapsulated within it, and the cooling agent can react with the cooling water to absorb heat.

[0008] Furthermore, the melting trigger housing includes a hollow housing and a melting plate. The hollow housing is disposed inside the heat-conducting outer shell, and the melting plate is fixedly embedded on the outer surface of the hollow housing. The cooling agent is encapsulated inside the hollow housing. The heat-conducting outer shell can conduct the heat released during the concrete solidification process to the melting plate, causing it to melt. After the melting plate melts, it can release the cooling agent inside the hollow housing.

[0009] Furthermore, the hollow shell is configured as a hollow cubic structure, and each side of the hollow shell is fixedly embedded with at least one of the molten sheets.

[0010] Furthermore, the melt-triggered housing also includes a seal, which is disposed between the molten sheet and the hollow housing to prevent leakage of the cooling agent before the molten sheet melts.

[0011] Furthermore, the thermally conductive outer shell is made of stainless steel; and / or

[0012] The hollow shell of the melt-triggered shell is made of stainless steel.

[0013] Furthermore, the heat-conducting outer shell is configured as a hollow cubic structure or a hollow spherical structure.

[0014] Furthermore, the molten sheet includes a potassium sheet.

[0015] Furthermore, the cooling agent includes calcium nitrate powder.

[0016] Furthermore, the multiple cooling components are distributed in layers along the vertical direction of the concrete.

[0017] Furthermore, the number density of the multiple cooling components distributed within the same horizontal layer of the concrete gradually decreases from the central region of the concrete outwards.

[0018] The beneficial effects of this utility model are:

[0019] This invention provides a concrete hydration heat cooling device, comprising multiple cooling components embedded within the concrete. Each cooling component includes a heat-conducting outer shell, a melting trigger shell, a cooling agent, and cooling water. By embedding these components in the concrete, the heat released during the concrete's solidification process is conducted to the melting trigger shell, triggering it to melt and release the cooling agent. This releases the cooling agent, which then reacts with the cooling water. The reaction is endothermic, absorbing the heat of hydration during concrete solidification and helping to lower the concrete's internal temperature, preventing cracks or strength reduction caused by hydration heat. This concrete hydration heat cooling device eliminates the need for a complex water pipe circulation system, reducing reliance on water pipes during construction, minimizing resource waste, avoiding the risk of pipe blockage, and reducing long-term maintenance and management costs. The device's overall design is portable, adaptable to various construction environments, and capable of stably controlling concrete temperature changes, thus improving the overall stability and durability of large-volume concrete construction.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0030] Please refer to Figures 1 to 3As shown, this utility model provides a concrete hydration heat cooling device that can effectively absorb and disperse the hydration heat of large-volume concrete 100 during the solidification process. It does not rely on a complex water pipe circulation system, thus avoiding resource waste and water pipe blockage, reducing maintenance and operating costs. At the same time, the device does not require complex cable connections, is easy to carry, adapts to various construction environments, and improves the stability and durability of large-volume concrete 100 during construction. A concrete hydration heat cooling device includes multiple cooling components 1, which are embedded in concrete 100. Each cooling component 1 includes a heat-conducting shell 2, a melting trigger shell 3, a cooling agent 4, and cooling water 5. The melting trigger shell 3 is located inside the heat-conducting shell 2, the cooling agent 4 is encapsulated inside the melting trigger shell 3, and the cooling water 5 fills the space between the melting trigger shell 3 and the heat-conducting shell 2. The heat-conducting shell 2 can conduct the heat released during the solidification process of the concrete 100 to the melting trigger shell 3, causing it to melt. After melting, the melting trigger shell 3 can release the cooling agent 4 encapsulated inside, and the cooling agent 4 can react with the cooling water 5 to absorb heat.

[0031] By embedding multiple cooling components 1 within the concrete 100, the heat released during the solidification of the concrete 100 due to the heat of hydration is conducted to the melting trigger shell 3 via the heat-conducting shell 2. This triggers the melting of the melting trigger shell 3, releasing the cooling agent 4 inside. The cooling agent 4 then reacts with the cooling water 5, and the reaction is endothermic, absorbing the heat of hydration during the solidification of the concrete 100. This helps reduce the temperature inside the concrete 100, preventing cracks or strength reduction caused by the heat of hydration. The concrete hydration heat cooling device does not rely on a complex water pipe circulation system, reducing dependence on the water pipe system during construction, reducing resource waste, avoiding the risk of water pipe blockage, and reducing maintenance and management costs during long-term operation. The overall design of the device is portable, adaptable to various construction environments, and can stably control the temperature changes of the concrete 100, contributing to improved overall stability and durability during the construction of large-volume concrete 100.

[0032] Combination Figure 2 and Figure 3As shown, specifically, the melting trigger shell 3 includes a hollow shell 31 and a melting plate 32. The hollow shell 31 is disposed inside the heat-conducting shell 2, and the melting plate 32 is fixedly embedded on the outer surface of the hollow shell 31. The cooling agent 4 is encapsulated inside the hollow shell 31. The heat-conducting shell 2 can conduct the heat released during the solidification of the concrete 100 to the melting plate 32, causing it to melt. After the melting plate 32 melts, it can release the cooling agent 4 inside the hollow shell 31. By fixing the melting plate 32 to the outer surface of the hollow shell 31, it can sense changes in the external temperature in a timely manner and more accurately control its own melting, thereby ensuring that the release of the cooling agent 4 occurs at the optimal time, thus improving the cooling effect. At the same time, the melting plate 32, as a triggering device, controls the release amount of the cooling agent 4 during its melting process, which helps to ensure that the cooling agent 4 is released gradually during the solidification of the concrete 100, avoiding the release of the cooling agent 4 too early or too late, thereby achieving a stable cooling effect.

[0033] To increase the release area of ​​the cooling agent 4, in some embodiments, the hollow shell 31 is designed as a hollow cubic structure, with at least one molten sheet 32 ​​fixedly embedded on each side of the hollow shell 31. By setting molten sheets 32 on each side of the hollow shell 31, the contact area during the melting process can be increased. The hollow cubic structure design allows the molten sheets 32 to uniformly contact the heat released by the concrete 100 on each side, ensuring a faster and more uniform release of the cooling agent 4, thereby ensuring the uniformity of heating of the molten sheets 32. The molten sheets 32 are distributed in different directions, effectively improving the cooling effect, allowing the cooling agent 4 to be released in more areas, thereby improving the overall cooling efficiency. Furthermore, the molten sheets 32 are located at the center of each side of the hollow shell 31, which ensures that the molten sheets 32 are heated more uniformly. Heat can be transferred from the periphery of the hollow shell 31 to the center, ensuring the uniformity of heating of the molten sheets 32, helping to avoid overheating or undercooling in certain areas, ensuring that the melting process of the entire molten sheet 32 ​​is consistent, thereby improving the cooling effect.

[0034] To prevent premature release of the cooling agent 4, in some embodiments, the melt-triggered housing 3 further includes a seal. The seal is located between the molten sheet 32 ​​and the hollow housing 31 to prevent leakage of the cooling agent 4 before the molten sheet 32 ​​melts. The seal effectively prevents premature leakage of the cooling agent 4 before the molten sheet 32 ​​melts, ensuring that the cooling agent 4 will not leak out before the molten sheet 32 ​​has received sufficient heat. This ensures that the cooling agent 4 is released only after the molten sheet 32 ​​has completely melted during the concrete 100 solidification process, achieving precise control over the release timing of the cooling agent 4. The seal may, but is not limited to, using a rubber sealing ring; no specific limitation is made here.

[0035] To enhance heat transfer efficiency, in some embodiments, the heat-conducting outer shell 2 is made of stainless steel; and / or the hollow shell 31 of the melt-triggered shell 3 is made of stainless steel. Stainless steel has good thermal conductivity, and using stainless steel for the heat-conducting outer shell 2 allows for efficient conduction of the heat released during the hydration of the concrete 100, ensuring rapid heat transfer to the melt-triggered shell 3, thereby effectively triggering the release of the cooling agent 4 and guaranteeing the cooling effect. Simultaneously, stainless steel also has strong corrosion resistance; using stainless steel for the hollow shell 31 of the melt-triggered shell 3 effectively resists erosion from moisture, the cooling agent 4, and other environmental factors.

[0036] Furthermore, the heat-conducting outer shell 2 is configured as a hollow cubic structure or a hollow spherical structure; wherein, the hollow cubic or hollow spherical structure can optimize the heat conduction path, so that the heat released by the concrete 100 during the solidification process can be quickly conducted to the melting trigger shell 3.

[0037] In some embodiments, the molten sheet 32 ​​may be, but is not limited to, a potassium sheet; wherein, potassium metal is solid at room temperature, but its melting point is low (its melting point is degrees), and potassium has good thermal conductivity, which can effectively absorb the heat from the hydration heat of concrete 100 degrees, and can melt rapidly when the temperature reaches its melting point. When the potassium sheet is heated and melted, it can quickly initiate a cooling reaction, thereby triggering the release of the cooling agent 4; and potassium is a relatively stable element that is not easily oxidized and corroded, and can maintain stability and reliability for a long time, effectively avoiding the premature release of the cooling agent 4.

[0038] To improve heat absorption efficiency, in some implementations, the cooling agent 4 includes calcium nitrate powder. Since calcium nitrate powder absorbs a large amount of heat when it dissolves, and its heat absorption effect is rapid and strong, it can quickly react and consume excessive heat. Therefore, when calcium nitrate powder is used as cooling agent 4, after the molten sheet 32 ​​of the molten trigger shell 3 melts, the calcium nitrate powder can quickly come into contact with and react with the cooling water 5, absorbing a large amount of heat of hydration, thereby effectively reducing the temperature of the concrete 100 and preventing the concrete 100 from becoming too hot due to the accumulation of heat of hydration during the solidification process, thus preventing quality problems such as hot cracks.

[0039] To improve the cooling effect of the concrete hydration heat cooling device, in some embodiments, multiple cooling components 1 are distributed in layers along the vertical direction of the concrete 100. By distributing multiple cooling components 1 in layers along the vertical direction of the concrete 100, it can be ensured that the hydration heat of different depth areas of the concrete 100 can be effectively controlled. Since the release of hydration heat of the concrete 100 is a layer-by-layer process, the multiple cooling components 1 distributed in layers can cool down in layers according to the temperature rise of different layers, avoiding excessive local temperature differences.

[0040] like Figure 1 As shown, furthermore, the quantity density of multiple cooling components 1 distributed within the same horizontal layer of concrete 100 gradually decreases from the center of concrete 100 to the surrounding areas. During the pouring and hydration process of concrete 100, heat is mainly concentrated in the central area of ​​concrete 100 because the central area is thicker and releases more heat from the hydration reaction, while the surrounding areas are relatively thinner and release less heat from hydration. Therefore, by gradually decreasing the distribution density of multiple cooling components 1 within the same horizontal layer from the center to the outside, it helps to more accurately match the heat distribution in different areas of concrete 100, ensuring that areas with higher heat receive more cooling treatment, thereby improving the overall cooling efficiency.

[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
