Description

Technical Field

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

[0002] Cold storage refers to facilities or buildings specifically designed for storing refrigerated and frozen products. Cold storage facilities are typically equipped with specialized refrigeration equipment and control systems to regulate temperature and humidity. To ensure the freshness and safety of stored products, the internal temperature of cold storage facilities is generally set at -70 degrees Celsius. A temperature of -70 degrees Celsius effectively protects the freshness and safety of stored products and reduces the growth and occurrence of bacteria. Cold storage facilities are widely used in industries such as food processing, pharmaceuticals, and chemicals, and are important facilities for ensuring product quality and extending the shelf life of goods.

[0003] A search revealed a utility model patent with publication number CN221648857U, which discloses a cold storage anti-frost structure. This anti-frost structure is fixed to the cold storage wall and includes an anti-frost base with a cavity. The cavity is open on the left side, and a heat-conducting base is fixedly connected within it. The heat-conducting base is open on the right side, and a heating plate is installed on it. The heating plate is in contact with the heat-conducting base, forming a heating chamber between them. An air inlet pipe is connected above the heat-conducting base. The anti-frost structure uses a combined structure, fixing multiple anti-frost structures to the cold storage wall to achieve defrosting. Heating by the heating plate provides heat to the anti-frost base, preventing heat transfer between the cold air and the cold storage wall, reducing frost formation, and achieving anti-frost effects while being low-cost and easy to maintain.

[0004] The aforementioned patent uses a heating plate to heat the anti-frost seat, preventing heat transfer between the cold air inside the cold storage and the walls, reducing frost buildup, and avoiding condensation. This achieves an anti-frost effect while being low-cost and easy to maintain. However, the anti-frost structure relies solely on the heating plate to prevent heat transfer between the cold air and the walls. As frost melts, water droplets form, and these droplets, if left on the heating plate for an extended period, can affect its heating efficiency, thus reducing the anti-frost effect.

[0005] Therefore, it is necessary to propose a cold storage with an anti-condensation structure to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a cold storage unit with an anti-frost structure. Through the cooperation of the internal parts of the anti-frost mechanism, the condensation of frost on the inner wall of the cold storage unit can be reduced, and the water droplets adhering to the inner wall of the cold storage unit can be easily drained, thereby reducing the frost formation on the inner wall of the cold storage unit. Through the cooperation of the internal parts of the spray mechanism, the humidity inside the cold storage unit can be increased, thereby reducing the probability of frost formation. This solves the problem in the prior art where the anti-frost structure only relies on heating plates for heating, thus preventing heat transfer between the cold air and the inner wall of the cold storage unit. Furthermore, the melting of frost produces water droplets, and the long-term adhesion of water droplets to the heating plates affects the heating effect of the heating plates, thereby reducing the anti-frost effect.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a cold storage with an anti-condensation structure, comprising a cold storage body, an anti-condensation mechanism installed and fixed on the outer wall of the cold storage body and extending through to the inner wall of the cold storage body, and a spray mechanism installed and fixed around the outer wall of the cold storage body and extending through to the inner wall of the cold storage body and located at the top of the anti-condensation mechanism;

[0008] The anti-condensation mechanism includes multiple anti-condensation plates, which are installed and fixed at a certain angle on the inner wall of the cold storage body. The outer wall of the cold storage body is bolted to the air inlet and extends into the interior of the cold storage body. The outer wall of the cold storage body is bolted to the air outlet, which is located at one end of the air inlet and extends into the interior of the cold storage body. A circulating air duct is bolted between the air inlet and the air outlet and is located inside the cold storage body.

[0009] The spraying mechanism includes a water tank, which is installed on the outer wall of the cold storage body and located below the air inlet and outlet. A water pump is bolted to the top of the water tank and extends into the interior of the water tank. Water inlet pipes are sealed and connected to both sides of the outer wall of the water pump and extend through the cold storage body to the inner wall of the cold storage body. An installation plate is sealed and fixed to the inner wall of the cold storage body and is sleeved with the outer wall of the water inlet pipe. Multiple atomizing nozzles are threadedly connected to the outer wall of the installation plate and are located above the anti-condensation plate.

[0010] Preferably, the anti-condensation mechanism further includes a heat-conducting plate, which is disposed between the anti-condensation plate and the main body of the cold storage, and a heat insulation plate is installed and connected to the outer wall of the main body of the cold storage.

[0011] Preferably, the anti-condensation plate is conical in shape, and drainage grooves are left between multiple anti-condensation plates. The surface of the anti-condensation plate is provided with an inert anti-condensation coating, the main component of which is polyethylene glycol.

[0012] Preferably, the connection between the air inlet, air outlet and the circulating air duct has excellent sealing performance, and the inner cavity of the cold storage body has an installation groove that matches the circulating air duct and fits snugly against the outer wall of the circulating air duct.

[0013] Preferably, the heat-conducting plate is mainly made of stainless steel, and the heat insulation plate is a polyurethane cold storage panel, mainly made of color steel plate as surface layer and rigid polyurethane foam as core layer.

[0014] Preferably, a temperature sensor and a controller are installed and fixed on the inner wall of the cold storage body, and the controller is connected to the atomizing nozzle through the mounting plate for control.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. Hot air is delivered to the circulating air duct through the air inlet. The hot air circulates in the circulating air duct to heat the main body of the cold storage. The heated main body of the cold storage is transferred to the inner wall of the cold storage through the heat conduction plate. This prevents heat transfer between the cold air in the cold storage and the inner wall of the cold storage, reducing the formation of frost. At the same time, the anti-frost plate is conical in shape and has drainage grooves between multiple anti-frost plates. The surface of the anti-frost plate is equipped with an inert anti-frost coating, which helps to reduce the interaction between water droplets and the surface of the cold storage, thereby reducing the possibility of frost formation and facilitating the dripping of water droplets from the surface of the cold storage, thus reducing the formation of frost on the inner wall of the cold storage.

[0017] 2. By starting the water pump, the water in the water tank is delivered to the inlet pipe, and then flows into the mounting plate. Temperature sensors and controllers are installed and fixed on the inner wall of the cold storage body. The controller passes through the mounting plate and is connected to the atomizing nozzles for control. The atomizing nozzles can spray quantitatively or at regular intervals under the control of the controller, thereby reducing the temperature and humidity inside the cold storage body, reducing the formation of frost, improving the anti-frost performance of the cold storage body, and ensuring the stability of the storage environment for the items placed in the cold storage body.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-5 The cold storage shown includes a cold storage body 1, an anti-condensation mechanism 2 installed and fixed on the outer wall of the cold storage body 1 and extending through to the inner wall of the cold storage body 1, and a spray mechanism 3 installed and fixed around the outer wall of the cold storage body 1 and extending through to the inner wall of the cold storage body 1 and located at the top of the anti-condensation mechanism 2.

[0028] The anti-condensation mechanism 2 includes multiple anti-condensation plates 201, which are installed and fixed at a certain angle on the inner wall of the cold storage body 1. The outer wall of the cold storage body 1 is bolted to the air inlet 202 and extends into the interior of the cold storage body 1. The outer wall of the cold storage body 1 is bolted to the air outlet 203, which is located at one end of the air inlet 202 and extends into the interior of the cold storage body 1. A circulating air duct 204 is bolted between the air inlet 202 and the air outlet 203 and is located inside the cold storage body 1.

[0029] The spraying mechanism 3 includes a water tank 301, which is installed on the outer wall of the cold storage body 1 and located below the air inlet 202 and the air outlet 203. A water pump 302 is bolted to the top of the water tank 301 and extends into the interior of the water tank 301. Water inlet pipes 303 are sealed and connected to both sides of the outer wall of the water pump 302 and extend through the cold storage body 1 to the inner wall of the cold storage body 1. An installation plate 304 is sealed and fixed to the inner wall of the cold storage body 1 and is sleeved with the outer wall of the water inlet pipe 303. Multiple atomizing nozzles 305 are threadedly connected to the outer wall of the installation plate 304 and are located above the anti-condensation plate 201.

[0030] By cooperating with each other among the internal parts of the anti-frost mechanism 2, the condensation of frost on the inner wall of the cold storage body 1 can be reduced, and the water droplets attached to the inner wall of the cold storage body 1 can be diverted, thereby reducing the frost formation on the inner wall of the cold storage body 1. By cooperating with each other among the internal parts of the spray mechanism 3, the humidity inside the cold storage body 1 can be increased, thereby reducing the probability of frost formation.

[0031] Refer to the instruction manual appendix Figure 1-5 The anti-condensation mechanism 2 also includes a heat-conducting plate 205, which is disposed between the anti-condensation plate 201 and the cold storage body 1. An insulation plate 206 is installed and connected to the outer wall of the cold storage body 1. Through the heat-conducting plate 205 and the insulation plate 206 inside the anti-condensation mechanism 2, it is easy to prevent the heat transfer between the cold air inside the cold storage body 1 and the outer wall.

[0032] Refer to the instruction manual appendix Figure 1-5 The anti-condensation plate 201 is conical in shape, and drainage grooves are left between multiple anti-condensation plates 201. The surface of the anti-condensation plate 201 is provided with an inert anti-condensation coating, the main component of which is polyethylene glycol. The conical shape of the anti-condensation plate 201 and the drainage grooves between multiple anti-condensation plates 201, along with the inert anti-condensation coating on the surface of the anti-condensation plate 201, facilitate the reduction of the interaction between water droplets and the surface of the cold storage body 1, thereby reducing the possibility of frost formation and facilitating the dripping of water droplets from the surface of the cold storage body 1.

[0033] Refer to the instruction manual appendix Figure 1-5 The connection between the air inlet 202, the air outlet 203 and the circulating air duct 204 has excellent sealing performance. The inner cavity of the cold storage body 1 has an installation groove that matches the circulating air duct 204 and is in close contact with the outer wall of the circulating air duct 204. The installation groove that matches the circulating air duct 204 and is in close contact with the outer wall of the circulating air duct 204 facilitates the heating of the inner cavity of the cold storage body 1 by the circulating air duct 204 and prevents the cold air in the cold storage from exchanging heat with the inner wall of the cold storage.

[0034] Refer to the instruction manual appendix Figure 1-5 The heat-conducting plate 205 is mainly made of stainless steel, while the insulation plate 206 is a polyurethane cold storage panel, mainly made of color steel plate as the surface layer and rigid polyurethane foam as the core layer. The main material of the heat-conducting plate 205 is stainless steel, and the insulation plate 206 is polyurethane cold storage panel, which makes it easy for the heat-conducting plate 205 to maintain stable performance in an environment of minus seventy degrees Celsius. In addition, the insulation plate 206 has good thermal insulation performance, which can effectively reduce the heat transfer between the inside and outside of the cold storage.

[0035] Refer to the instruction manual appendix Figure 1-5A temperature sensor and a controller are installed and fixed on the inner wall of the cold storage body 1. The controller passes through the mounting plate 304 and is connected to the atomizing nozzle 305 for control. By installing and fixing the temperature sensor and the controller on the inner wall of the cold storage body 1, and by connecting the controller through the mounting plate 304 to the atomizing nozzle 305 for control, the atomizing nozzle 305 can spray quantitatively or at regular intervals under the control of the controller, thereby reducing the temperature and humidity inside the cold storage body 1 and reducing the formation of frost.

[0036] The working principle of this practical application is as follows:

[0037] Refer to the instruction manual appendix Figure 1-5 Hot air is delivered to the circulating air duct 204 through the air inlet 202. The hot air circulates in the circulating air duct 204 to heat the cold storage body 1. The heated cold storage body 1 transfers heat to the inner wall of the cold storage body 1 through the heat conduction plate 205, which can prevent the cold air in the cold storage body 1 from exchanging heat with the inner wall of the cold storage body 1 and reduce the formation of frost. At the same time, the anti-frost plate 201 is conical in shape and has drainage grooves between multiple anti-frost plates 201. The surface of the anti-frost plate 201 is provided with an inert anti-frost coating, which makes it easier for the anti-frost plate 201 to reduce the interaction between water droplets and the surface of the cold storage body 1, thereby reducing the possibility of frost formation and making it easier for water droplets to drip off the surface of the cold storage body 1. Thus, in the low temperature cold storage of -70 degrees, the formation of frost on the inner wall of the cold storage body 1 can be reduced.

[0038] Refer to the instruction manual appendix Figure 1-5 By starting the water pump 302, the water pump 302 delivers water from the water tank 301 to the water inlet pipe 303, and then flows through the water inlet pipe 303 into the mounting plate 304. A temperature sensor and controller are installed and fixed on the inner wall of the cold storage body 1, and the controller passes through the mounting plate 304 and is connected to the atomizing nozzle 305 for control. The atomizing nozzle 305 can spray quantitatively or at regular intervals under the control of the controller, thereby reducing the temperature and humidity inside the cold storage body 1, keeping the internal temperature of the cold storage body 1 stable at -70 degrees Celsius, and reducing the formation of frost. This improves the anti-frost performance of the cold storage body 1 and ensures the stability of the storage environment for the items placed in the cold storage body 1.
