Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of plastic parts for cooling systems, specifically a plastic part for cooling systems with strong anti-shrinkage ability. Background Technology
[0002] Plastic components are widely used in cooling systems across numerous fields, including automobiles and industrial equipment, due to their advantages such as light weight, low cost, and ease of processing and molding. However, existing plastic components for cooling systems suffer from several serious problems regarding shrinkage resistance, which significantly limit the performance, reliability, and service life of the cooling systems.
[0003] During operation, cooling systems experience frequent and significant temperature changes. Most existing cooling system plastic components are made of ordinary plastic materials, which have a relatively high coefficient of thermal expansion. When the cooling system starts and the temperature rises, the plastic components expand due to thermal expansion; conversely, when the system stops and the temperature drops, the plastic components contract due to cooling. This repeated process of thermal expansion and contraction causes significant changes in the dimensions of the plastic components, leading to gaps or interference fits between them and other components in the cooling system. For example, gaps may form at the connection between the plastic components and pipes due to contraction, causing coolant leakage, affecting the normal operation of the cooling system, and potentially even triggering [further problems]. Serious consequences such as equipment overheating and damage; In cold regions or low-temperature winter environments, the performance of existing cooling system plastic components will be severely affected. Ordinary plastics become brittle and hard at low temperatures, the movement of their molecular chains is restricted, and the toughness of the material is greatly reduced. When plastic components are subjected to external forces or due to the release of their own stress, they are prone to brittle shrinkage and cracking. For example, plastic water tanks in the cooling system may crack at low temperatures, leading to coolant leakage. This not only affects the cooling effect but may also cause corrosion and damage to surrounding equipment. Moreover, this brittle shrinkage is often irreversible. Once the plastic component cracks, it needs to be replaced, increasing maintenance costs and downtime. Utility Model Content
[0004] The purpose of this invention is to provide a cooling system plastic component with strong shrinkage resistance, addressing the issue mentioned in the background art. During operation, cooling systems experience frequent and significant temperature changes. Existing cooling system plastic components mostly use ordinary plastic materials, which have relatively high coefficients of thermal expansion. When the cooling system starts and the temperature rises, the plastic component increases in size due to thermal expansion; conversely, when the system stops working and the temperature drops, the plastic component decreases in size due to cooling contraction. This repeated thermal expansion and contraction process causes significant changes in the size of the plastic component, leading to gaps or interference fits between it and other components in the cooling system. For example, gaps may form at the connection between the plastic component and the pipe due to contraction, causing coolant leakage. This can affect the normal operation of the cooling system and may even lead to serious consequences such as overheating and damage to equipment. In cold regions or low-temperature winter environments, the performance of existing cooling system plastic components will be severely affected. Ordinary plastics become brittle and hard at low temperatures, the movement of their molecular chains is restricted, and the toughness of the material is greatly reduced. When plastic components are subjected to external forces or when their own stress is released, they are prone to brittle shrinkage and cracking. For example, plastic water tanks in the cooling system may crack at low temperatures, leading to coolant leakage. This not only affects the cooling effect but may also cause corrosion and damage to surrounding equipment. Moreover, this brittle shrinkage is often irreversible. Once a plastic component cracks, it needs to be replaced, increasing maintenance costs and downtime.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a cooling system plastic component with strong anti-shrinkage capability, comprising a plastic sheet, wherein a protective layer is fixedly connected to the outer surface of the plastic sheet, and the interior of the protective layer includes a chemical corrosion resistant layer, a thermal expansion buffer layer, a structural reinforcement core layer, and a stress dispersion transition layer, wherein the structural reinforcement core layer is disposed outside the stress dispersion transition layer, the thermal expansion buffer layer is disposed outside the structural reinforcement core layer, and the chemical corrosion resistant layer is disposed outside the thermal expansion buffer layer.
[0006] Compared with the prior art, the beneficial effects of this utility model are: This cooling system's plastic components, characterized by strong shrinkage resistance, feature a fluoropolymer coating in a chemically resistant layer. This coating boasts extremely low surface energy and excellent chemical stability, effectively resisting the erosion of various chemical components in the coolant and reducing the rapid heat transfer to the plastic sheet. A nano-silica cross-linked layer further enhances the coating's density and stability, forming a robust barrier. A thermal expansion buffer layer, adjacent to the chemically resistant layer, incorporates a shape memory polymer layer with unique shape memory properties. As temperature rises, it absorbs some of the stress generated by thermal expansion through its elastic deformation, mitigating the expansion tendency of the plastic sheet. The microporous foam layer is filled with numerous tiny pores, which can buffer thermal expansion. The impact effect disperses stress and prevents excessive enlargement of plastic parts. These two elements work together to significantly reduce the thermal expansion of the plastic parts as temperatures rise, effectively preventing gaps between the plastic parts and other components in the cooling system due to thermal expansion. This ensures the sealing and normal operation of the cooling system. The continuous glass fiber braided layer in the structural reinforcement core layer has high strength and high modulus, providing strong structural support for the plastic parts and enhancing their resistance to cold shrinkage deformation. The carbon nanotube modified interface layer improves the interfacial bonding performance between the continuous glass fiber and the plastic matrix, allowing for more uniform stress transmission and reducing stress concentration. The gradient elastic modulus layer in the stress dispersion transition layer has a gradually changing elastic modulus, which can gradually disperse stress in the plastic parts. The cooling stress generated by temperature drop prevents stress concentration and cracking of plastic parts. The microcapsules in the microencapsulated lubricant layer rupture under stress, releasing lubricant to reduce friction between internal layers and further alleviate cooling stress. These two layers work together to effectively resist brittle shrinkage of plastic parts at low temperatures, preventing cracks in components such as plastic water tanks, avoiding coolant leakage, and ensuring the reliability of the cooling system and the safety of surrounding equipment. The shape memory polymer layer of the thermal expansion buffer layer maintains a certain degree of flexibility at low temperatures, unlike ordinary plastics which quickly become brittle. It absorbs energy through elastic deformation when the plastic part is subjected to external forces or releases its own stress, reducing the plastic's brittleness. The microporous structure of the microporous foam layer reduces the possibility of brittle shrinkage and cracking in plastic parts. It also provides a buffering effect at low temperatures, dispersing stress and reducing the brittleness of the plastic parts. This allows the cooling system plastic parts to maintain good performance in cold regions or low-temperature winter environments, extending their service life and reducing maintenance and replacement costs caused by low-temperature brittle shrinkage. The continuous glass fiber braided layer and carbon nanotube modified interface layer of the structural reinforcement core layer synergistically enhance the toughness of the plastic parts at low temperatures. The high strength and high modulus of the continuous glass fiber braided layer limit the deformation of the plastic parts, while the carbon nanotube modified interface layer improves the interfacial bonding between the fibers and the matrix, making stress transmission more uniform and improving the impact resistance of the plastic parts at low temperatures.Even under low-temperature conditions and subjected to external forces, the plastic parts are not prone to brittle fracture, ensuring the normal operation of the cooling system under low-temperature conditions. The fluoropolymer coating of the chemical corrosion resistant layer has excellent chemical corrosion resistance, resisting the erosion of various chemical components in the coolant, such as ethylene glycol, preservatives, and additives. The nano-silica cross-linked layer and the fluoropolymer coating cross-link with each other, forming a denser protective structure, further improving the chemical corrosion resistance. This dual protective structure effectively prevents the coolant from directly contacting the plastic sheet, avoiding the degradation of material properties such as reduced strength caused by chemical corrosion. This design addresses issues such as reduced toughness and shrinkage, thereby minimizing the shrinkage of plastic parts caused by chemical corrosion under temperature changes and extending their service life. The multi-layered protective layer and the internal reinforcing skeleton of the plastic sheet work together to reduce coolant penetration and corrosion. The reinforcing skeleton increases the overall structural strength of the plastic part, making it less prone to deformation and shrinkage under chemical corrosion. Simultaneously, the tight bonding between layers prevents the diffusion of corrosive media within the plastic part, reducing the impact of chemical corrosion on the shrinkage resistance of the plastic part and ensuring the long-term durability of the cooling system's plastic parts in complex chemical environments. Stable operation is ensured by the reinforcing skeleton within the plastic sheet, which provides basic structural support and enhances the overall strength of the plastic component. The continuous glass fiber braided layer and carbon nanotube modified interface layer of the structural reinforcement core further strengthen the structure of the plastic component. The high-strength fiber network of the continuous glass fiber braided layer can withstand greater external forces, while the carbon nanotube modified interface layer improves the bonding strength between the fibers and the plastic matrix, allowing stress to be transferred and dispersed more effectively. The combination of these two elements enables the plastic component to better resist external forces such as pressure, vibration, and impact during the operation of the cooling system, reducing deformation and shrinkage caused by external forces and improving the structural stability and reliability of the plastic component. The gradient elastic modulus layer and microcapsule lubricant layer of the stress dispersion transition layer optimize the stress distribution inside the plastic component. The gradual change in elastic modulus of the gradient elastic modulus layer allows stress to be gradually dispersed, avoiding localized stress concentration. The lubricant released by the microcapsule lubricant layer reduces the friction between layers, reducing energy loss during stress transmission and allowing stress to be distributed more evenly inside the plastic component. This optimized stress distribution helps reduce shrinkage and deformation of the plastic component under temperature changes and external forces, improving the overall performance and service life of the plastic component. , Attached Figure Description

[0010] Please see Figure 1-6 This utility model provides a technical solution: a cooling system plastic part with strong anti-shrinkage ability, including a plastic plate 1, a protective layer 3 fixedly connected to the outer surface of the plastic plate 1, and the interior of the protective layer 3 including a chemical corrosion resistant layer 4, a thermal expansion buffer layer 5, a structural reinforcement core layer 6 and a stress dispersion transition layer 7.

[0015] The stress dispersion transition layer 7 includes a gradient elastic modulus layer 14 and a microcapsule lubricant layer 15.
[0016] In summary: This cooling system plastic component with strong shrinkage resistance, through the fluoropolymer coating 8 in the chemical corrosion resistant layer 4, possesses extremely low surface energy and excellent chemical stability. It not only effectively resists the erosion of various chemical components in the coolant but also reduces the rapid heat transfer to the plastic plate 1 to a certain extent. The nano-silica cross-linked layer 9 further enhances the density and stability of the coating, forming a robust barrier. The thermal expansion buffer layer 5 is adjacent to the chemical corrosion resistant layer 4, and its shape memory polymer layer 10 has a unique shape memory function. When the temperature rises, it can absorb some of the stress generated by the thermal expansion of the plastic component through its own elastic deformation, alleviating the expansion tendency of the plastic plate 1. The microporous foam layer 11 is filled with a large number of tiny pores. The gaps can act as a buffer during thermal expansion, dispersing stress and preventing excessive enlargement of plastic parts. Working together, these two elements significantly reduce the degree of thermal expansion of the plastic parts as temperatures rise, effectively preventing gaps between the plastic parts and other components in the cooling system due to thermal expansion. This ensures the sealing and normal operation of the cooling system. The continuous glass fiber braided layer 12 in the structural reinforcement core layer 6 has high strength and high modulus, providing strong structural support for the plastic parts and enhancing their resistance to cold shrinkage deformation. The carbon nanotube modified interface layer 13 improves the interfacial bonding performance between the continuous glass fiber and the plastic matrix, allowing stress to be transmitted more evenly and reducing stress concentration. The gradient elastic modulus layer 14 in the stress dispersion transition layer 7 has elasticity... The gradual modulus variation helps to disperse the shrinkage stress generated in plastic parts as the temperature decreases, preventing stress concentration and cracking. The microcapsules in the microencapsulated lubricant layer 15 rupture under stress, releasing lubricant and reducing friction between the internal layers of the plastic part, further alleviating shrinkage stress. These two layers work together to effectively resist brittle shrinkage of the plastic part at low temperatures, preventing cracks in components such as plastic water tanks, avoiding coolant leakage, and ensuring the reliability of the cooling system and the safety of surrounding equipment. The shape memory polymer layer 10 of the thermal expansion buffer layer 5 maintains a certain degree of flexibility at low temperatures, unlike ordinary plastics which quickly become brittle. It can withstand external forces or its own stress release within the plastic part. At low temperatures, the plastic parts absorb energy through elastic deformation, reducing the possibility of brittle shrinkage and cracking. The microporous structure of the microporous foam layer 11 also plays a certain buffering role at low temperatures, dispersing stress and reducing the brittleness of the plastic parts. This allows the plastic parts of the cooling system to maintain good performance in cold regions or low-temperature winter environments, extending the service life of the plastic parts and reducing maintenance and replacement costs caused by low-temperature brittle shrinkage. The continuous glass fiber braided layer 12 and the carbon nanotube modified interface layer 13 of the structural reinforcement core layer 6 can synergistically enhance the toughness of the plastic parts at low temperatures. The high strength and high modulus of the continuous glass fiber braided layer 12 can limit the deformation of the plastic parts, while the carbon nanotube modified interface layer 13 improves the interfacial bonding between the fibers and the matrix.This design ensures more uniform stress distribution and improves the impact resistance of plastic parts at low temperatures. Even when subjected to external forces at low temperatures, the plastic parts are less prone to brittle fracture, guaranteeing the normal operation of the cooling system under low-temperature conditions. The fluoropolymer coating 8 of the chemical corrosion resistant layer 4 has excellent chemical corrosion resistance, resisting the erosion of various chemical components in the coolant, such as ethylene glycol, preservatives, and additives. The nano-silica cross-linked layer 9 cross-links with the fluoropolymer coating 8, forming a denser protective structure that further improves chemical corrosion resistance. This dual protective structure effectively prevents direct contact between the coolant and the plastic plate 1, avoiding damage to the plastic parts caused by chemical corrosion. Corrosion leads to a decline in material properties, such as reduced strength and toughness. This reduces shrinkage of plastic parts caused by chemical corrosion under temperature changes, extending their service life. The multi-layered structure of the protective layer 3, along with the reinforcing skeleton 2 inside the plastic plate 1, works together to reduce coolant penetration and corrosion into the plastic parts. The reinforcing skeleton 2 increases the overall structural strength of the plastic parts, making them less prone to deformation and shrinkage under chemical corrosion. Simultaneously, the tight bonding between layers prevents the diffusion of corrosive media within the plastic parts, reducing the impact of chemical corrosion on the shrinkage resistance of the plastic parts and ensuring the cooling system's plastic parts withstand complex conditions. During long-term stable operation in a chemical environment, the reinforcing skeleton 2 inside the plastic plate 1 provides basic structural support for the plastic component, enhancing its overall strength. The continuous glass fiber braided layer 12 and the carbon nanotube modified interface layer 13 of the structural reinforcement core layer 6 further strengthen the structure of the plastic component. The high-strength fiber network of the continuous glass fiber braided layer 12 can withstand greater external forces, while the carbon nanotube modified interface layer 13 improves the bonding strength between the fiber and the plastic matrix, enabling stress to be transferred and dispersed more effectively. The combination of these two elements allows the plastic component to better resist external forces such as pressure, vibration, and impact during the operation of the cooling system, reducing stress caused by external forces. The stress dispersion transition layer 7, consisting of a gradient elastic modulus layer 14 and a microcapsule lubricant layer 15, optimizes the stress distribution within the plastic part, reducing deformation and shrinkage. This improves the structural stability and reliability of the plastic part. The gradient elastic modulus layer 14's gradual change in elastic modulus allows stress to be gradually dispersed, preventing localized stress concentration. The lubricant released by the microcapsule lubricant layer 15 reduces friction between layers, minimizing energy loss during stress transmission and allowing for a more uniform stress distribution within the plastic part. This optimized stress distribution helps reduce shrinkage and deformation of the plastic part under temperature changes and external forces, improving its overall performance and service life.
