Description

Technical Field

[0001] This utility model relates to the field of cold storage technology, specifically to a cold storage anti-condensation device. Background Technology

[0002] In the fields of cold chain logistics, food storage, and pharmaceutical refrigeration, cold storage facilities, as core storage equipment, have long been hampered by frost buildup on their inner walls and surfaces, which restricts their operational efficiency and lifespan. During operation, the temperature difference between the low-temperature environment inside the cold storage and the external environment causes moisture in the air to easily condense into frost on the surface of the storage unit. At the same time, the respiration of goods inside the storage unit or the evaporation of moisture carried by packaging also leads to the accumulation of frost layers on the surface.

[0003] The main problems with frost buildup in cold storage are as follows: Frost adheres to the surface of the storage unit, significantly reducing its heat exchange efficiency. This forces the refrigeration system to consume more energy to maintain the set low temperature, increasing operating costs. Furthermore, long-term frost accumulation can lead to uneven local temperatures within the storage unit, affecting the quality and stability of stored goods, particularly fresh food and pharmaceuticals requiring strict temperature control. In addition, traditional cold storage solutions primarily rely on periodic manual defrosting or electric defrosting. Manual defrosting is labor-intensive, inefficient, and requires interrupting normal operation, disrupting storage continuity. Electric defrosting, on the other hand, is energy-intensive, prone to uneven heating leading to localized temperature fluctuations, and if melted water is not promptly removed, it can refreeze and form new frost layers, failing to fundamentally solve the frost problem.

[0004] Meanwhile, although some existing cold storage facilities have attempted to improve the frost problem by optimizing the sealing of the storage body or adding simple water guiding structures, the sealing structure is prone to failure due to low-temperature aging after long-term use, which leads to the infiltration of external water vapor and aggravates frost; and traditional water guiding structures are mostly single-groove designs, which cannot achieve rapid and complete drainage of water, and there is still a situation where water remains and freezes.

[0005] Therefore, there is a need to provide a cold storage anti-condensation device to solve this problem. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a cold storage anti-condensation device, which has the advantages of high efficiency in anti-condensation, full utilization of heat, thorough drainage of moisture and strong adaptability. It solves the problems of existing cold storage bodies being prone to condensation of frost on the surface due to temperature differences, resulting in reduced heat exchange efficiency and increased operating energy consumption; low efficiency and easy temperature fluctuations caused by manual or electric heating defrosting methods; and incomplete drainage and easy secondary freezing of traditional water guiding structures.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cold storage anti-condensation device, comprising a cold storage body, the surface of which is fixedly connected with a plurality of uniformly and equidistantly distributed grooves, the bottom of which is fixedly connected with a bottom strip, the top of which is provided with a guide groove, which is used in conjunction with the cold storage body and the grooves respectively, the inner side of which is provided with a heating chamber, the side of which near the grooves is fixedly connected with a heat-conducting plate adapted to the plurality of grooves, the surface of which is bonded with an insulation board, the area between which the heat-conducting plate and the insulation board is provided with a serpentine connecting groove, the inside of which is installed with a heat exchange tube adapted to the shape of the connecting groove, the two ends of which pass through the bottom strip and are connected to a circulating pump with a heating function, the top of which is fixedly connected with a diverter strip, the bottom of which is connected to a plurality of uniformly arranged atomizing nozzles, and the plurality of atomizing nozzles are respectively in a one-to-one correspondence with the plurality of grooves.

[0010] As a preferred embodiment of this invention, the heat-conducting plate is fixedly connected to a uniformly arranged heat-conducting block on the side near the groove, and the heat-conducting block is in contact with the container body.

[0011] As a preferred embodiment of this utility model, a plurality of longitudinally uniformly arranged heat-spreading grooves are provided between the heat-conducting plate and the insulation plate, and the heat-spreading grooves are connected to the connecting grooves. Heat-conducting pipes are installed inside the heat-spreading grooves, and the heat-conducting pipes are in contact with the heat exchange pipes.

[0012] As a preferred embodiment of this invention, the inner side of the storage body is provided with an anti-frost coating, and the surface of the anti-frost coating is provided with a low-temperature resistant and wear-resistant coating.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by setting several evenly distributed grooves on the surface of the silo body, combined with the guide grooves on the bottom strip of the silo body that cooperate with the silo body and the grooves, can guide condensate to quickly collect and drain, avoiding water accumulation on the surface of the silo body and freezing into frost; at the same time, the heat-conducting plate in the heating cavity inside the silo body is adapted to the grooves, and the heat exchange tube in the groove is connected to the insulation plate.

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.

[0018] like Figures 1 to 6As shown, the present invention provides a cold storage anti-condensation device, comprising a cold storage body 1, a plurality of uniformly and equidistantly distributed grooves 2 fixedly connected to the surface of the cold storage body 1, a bottom strip 3 fixedly connected to the bottom of the cold storage body 1, a guide groove 4 opened at the top of the bottom strip 3, and the guide groove 4 is used in conjunction with the cold storage body 1 and the grooves 2 respectively, a heating chamber 5 is opened on the inner side of the cold storage body 1, a heat-conducting plate 6 adapted to the plurality of grooves 2 is fixedly connected to the side of the heating chamber 5 near the grooves 2, an insulation plate 7 is bonded to the surface of the heat-conducting plate 6, a serpentine connecting groove 8 is opened in the area between the heat-conducting plate 6 and the insulation plate 7, a heat exchange tube 9 adapted to the shape of the connecting groove 8 is installed inside the connecting groove 8, the two ends of the heat exchange tube 9 pass through the bottom strip 3 and are connected to a circulating pump 10 with heating function, and a diversion strip 11 is fixedly connected to the top of the cold storage body 1, a plurality of uniformly arranged atomizing nozzles 12 are connected to the bottom of the diversion strip 11, and the plurality of atomizing nozzles 12 are respectively in a one-to-one correspondence with the plurality of grooves 2.

[0019] refer to Figure 1 and Figure 4 The groove 2 has several evenly arranged guide ports 13 on its groove wall, and the guide ports 13 are used in conjunction with the guide groove 4.

[0020] As a technical optimization of this utility model, by opening a number of evenly arranged guide ports 13 on the wall of the groove 2 and using them in conjunction with the guide channel 4, the water formed after condensation in the groove 2 can be quickly introduced into the guide channel 4, preventing the water from accumulating in the groove 2 and freezing into frost again, thereby further improving the anti-frost effect.

[0021] refer to Figure 2 and Figure 3 The inlet of the diversion bar 11 is connected to the heater 14, the input end of the heater 14 is connected to the water storage tank 15, the bottom of the water storage tank 15 is connected to the water inlet pump 16, and the input end of the water inlet pump 16 is connected to the guide channel 4.

[0022] As a technical optimization of this utility model, a water circulation system is constructed by connecting the inlet of the diversion strip 11 to the heater 14, the input end of the heater 14 to the water storage tank 15, and the bottom of the water storage tank 15 to the inlet pump 16 connected to the guide channel 4. The inlet pump 16 pumps water from the guide channel 4 to the water storage tank 15, heats it after being heated by the heater 14, and then delivers it to the diversion strip 11. It is then sprayed onto the groove 2 by the atomizing nozzle 12, using warm water to further suppress the formation of frost, while realizing the recycling of water resources.

[0023] refer to Figure 6 A uniformly arranged heat-conducting block 17 is fixedly connected to the side of the heat-conducting plate 6 near the groove 2, and the heat-conducting block 17 is in contact with the housing 1. The heat-conducting block 17 is made of a composite material of graphite and copper.

[0024] As a technical optimization of this utility model, several heat-conducting blocks 17, which are in contact with the heat-conducting plate 6 and made of graphite and copper composite material, are fixedly connected to the side of the heat-conducting plate 6 near the groove 2. The graphite and copper composite material has excellent thermal conductivity, which can transfer the heat of the heat-conducting plate 6 to the surface of the heat-conducting plate 1 more efficiently and evenly, and avoid the local temperature of the heat-conducting plate 1 from being too low and condensing frost.

[0025] refer to Figure 3 and Figure 5 A number of longitudinally uniformly arranged heat-spreading grooves 18 are provided between the heat-conducting plate 6 and the insulation plate 7, and the heat-spreading grooves 18 are connected to the connecting grooves 8. Heat-conducting pipes 19 are installed inside the heat-spreading grooves 18, and the heat-conducting pipes 19 are in contact with the heat exchange pipes 9.

[0026] As a technical optimization of this utility model, several longitudinal heat-spreading grooves 18 connected to the connecting grooves 8 are opened between the heat-conducting plate 6 and the insulation plate 7, and heat-conducting pipes 19 that are in contact with the heat exchange pipes 9 are installed in the heat-spreading grooves 18. The heat-conducting pipes 19 can conduct the heat of the heat exchange pipes 9 to each area of ​​the heat-spreading grooves 18, so that the heat-conducting plate 6 is heated more evenly and the heating and anti-condensation effect on the storage body 1 is improved.

[0027] refer to Figure 1 The inner side of the cold storage body 1 is provided with an anti-condensation coating, which can be made of fluorosilicone modified acrylic coating. The surface contact angle of this coating can reach more than 150°, and it is superhydrophobic. Water vapor is difficult to adhere to the inner surface of the cold storage body 1, which can delay the frost time by 5 to 8 hours. At the same time, it has good low temperature resistance, and there is no cracking or peeling at -60°C. It does not peel even when exposed to the humid environment of the cold storage for a long time. The surface of the anti-condensation coating is provided with a low temperature wear-resistant coating, which can be made of polyurethane modified epoxy resin coating. The polyurethane modified epoxy resin coating has both elasticity and wear resistance, and can resist the slight impact when the goods are handled in the cold storage, protecting the anti-condensation coating below from being scratched.

[0028] As a technical optimization of this utility model, by setting an anti-frost coating and a low-temperature wear-resistant coating, the anti-frost coating can reduce the adhesion of frost from the source, while the low-temperature wear-resistant coating can protect the anti-frost coating from wear in low-temperature environments and daily use, extend the service life of the anti-frost coating, and continuously ensure the anti-frost effect.

[0029] The working principle and usage process of this utility model are as follows: When using this cold storage anti-condensation device, firstly, the circulating pump 10 with heating function is started. The circulating pump 10 drives the heat exchange medium to flow in the heat exchange tube 9. The heat exchange tube 9 is installed in the serpentine connecting groove 8 opened between the heat-conducting plate 6 and the insulation plate 7. The heat carried by the heat exchange medium is transferred to the heat-conducting plate 6 through the heat exchange tube 9. At the same time, the heat-conducting tube 19 (installed in the longitudinal heat-equalizing groove 18 opened between the heat-conducting plate 6 and the insulation plate 7 and connected to the connecting groove 8) which is in contact with the heat exchange tube 9 further conducts the heat to various areas of the heat-conducting plate 6, so that the heat-conducting plate 6 is heated evenly. The heat-conducting block 17, which is fixedly connected to the side of the heat-conducting plate 6 near the groove 2 and is in contact with the cold storage body 1 and is made of graphite and copper composite material, efficiently transfers the heat of the heat-conducting plate 6 to the surface of the cold storage body 1, avoiding local temperature drops in the cold storage body 1. At the same time, the anti-condensation coating set on the inner side of the cold storage body 1 reduces the adhesion of water vapor on the inner side of the cold storage body 1, and the low-temperature resistant and wear-resistant coating set on its surface protects the cold storage body 1. The anti-frost coating is protected from wear. Then, the water inlet pump 16 is started. The water inlet pump 16 pumps the water in the guide channel 4 opened at the top of the bottom strip 3 and used in conjunction with the tank body 1 and the groove 2 to the water storage tank 15. The water in the water storage tank 15 is delivered to the heater 14. After being heated by the heater 14, it is delivered to the diversion strip 11 fixedly connected to the top of the tank body 1. The atomizing nozzle 12 connected to the bottom of the diversion strip 11 and corresponding to the groove 2 sprays warm water into several uniformly distributed grooves 2 fixedly connected to the surface of the tank body 1, further inhibiting the formation of frost in the grooves 2. Several uniformly arranged guide ports 13 opened on the groove wall of the groove 2 (used in conjunction with the guide channel 4) guide the water condensed in the groove 2 into the guide channel 4, realizing the recycling of water resources. Throughout the process, the heat insulation plate 7 prevents the heat in the heating chamber 5 (opened on the inside of the tank body 1, with a heat-conducting plate 6 fixedly connected to the side near the groove 2 that is compatible with the groove 2) from dissipating outward, ensuring that the heat is used efficiently for anti-frost and maintaining the stable operation of the device.

[0030] In some feasible embodiments, temperature and humidity sensors and controllers can be added inside the storage tank 1 to achieve automatic temperature and humidity control.

[0031] It should be noted that the material of the heat-conducting plate 6 can be, but is not limited to, ALSiC-10 (aluminum silicon carbide composite material) or 6063-T5 aluminum alloy. ALSiC-10 composite material combines lightweight and high thermal conductivity, enabling rapid heat transfer from the heat exchange tube 9 to the cold storage body 1, preventing localized low-temperature frost formation. It also has a low coefficient of thermal expansion, ensuring high compatibility with the metal substrate of the cold storage body 1 and preventing cracking due to thermal expansion and contraction over long-term use. 6063-T5 aluminum alloy is less expensive than composite materials and has excellent processing performance, allowing for customized fit structures based on the shape of the groove 2, balancing thermal conductivity and installation compatibility. The material of the insulation board 7 can be, but is not limited to, polyurethane foam board or vacuum insulation board. Polyurethane foam board effectively blocks heat loss from the heating chamber 5 to the outside, reducing the heating energy consumption of the circulating pump 10. It also exhibits excellent low-temperature resistance, adapting to the low-temperature environment of the cold storage, and exhibits no shrinkage or deformation over long-term use. Vacuum insulation board has an extremely low thermal conductivity, only 1 / 5 to 1 / 8 of traditional insulation materials, enabling… The thickness of the insulation board 7 is significantly reduced, saving internal space in the heating chamber 5 and further reducing heat loss, thus improving the overall energy efficiency of the device. This design is suitable for compact cold storage interiors. The heat pipe 19 can be made of, but is not limited to, soft seamless copper or stainless steel. Copper has a high thermal conductivity, which can quickly transfer the heat from the heat exchanger 9 to the entire heat spreader 18, ensuring uniform heating of the heat exchanger 6 (temperature difference can be controlled within ±2℃), and preventing frost formation caused by local temperature fluctuations in the storage chamber 1. Copper is also highly corrosion-resistant and has good compatibility with the circulating medium (such as antifreeze) in the heat exchanger 9, preventing rust and blockage during long-term use. Stainless steel has excellent low-temperature performance (maintaining toughness even at -196℃), making it suitable for ultra-low temperature cold storage (such as below -40℃). 316L material has strong resistance to chloride ion corrosion, which can prevent corrosion and perforation inside the pipe if the circulating medium contains trace impurities, extending its service life. Furthermore, stainless steel has high mechanical strength, making it less prone to bending and deformation during installation, thus improving heat conduction.
