Description

TECHNICAL FIELD

[0001] The utility model relates to building material technical field, concretely relates to a prevent melting ice brick. BACKGROUND

[0002] At present, ice products such as ice sculpture, ice building, ice landscape and ice decoration have been more maturely applied in the cold winter in the north, and its manufacturing process mainly depends on natural low-temperature environment or low-temperature storage condition.However, with the growing demand for the application of ice culture and ice landscape throughout the year or even in the south, the traditional method of relying on external low-temperature condition to maintain the stability of ice body cannot meet the long-term use requirements of ice products in summer or warm environment.

[0003] The main solutions of traditional technology are concentrated in the following aspects:

[0004] Low-temperature storage and transportation: after the completion of ice products, it needs to rely on cold storage, refrigerator or refrigerated vehicle for storage to avoid rapid melting in high-temperature environment.This way not only limits the application scene of ice products, but also greatly increases the operation cost and logistics difficulty.

[0005] Thermal insulation measures: some technologies try to slow down the heat exchange between ice body and surrounding high-temperature environment by adding thermal insulation layer or spraying special coating on the surface of ice body, but this method is still difficult to achieve effective anti-melting effect when exposed to high temperature for a long time.

[0006] Local cooling means: some solutions use local cooling device to cool the ice body, but often have problems such as high energy consumption, complex system and insufficient control precision, which is difficult to achieve stable effect in large area or dynamic environment.

[0007] Therefore, the existing technology has not yet provided an economical and efficient structured solution to make the ice body remain frozen in an environment above zero degrees Celsius.For this problem, the utility model provides a technical solution that sets up hollow refrigerant pipeline inside or at the edge of ice brick, and uses low-temperature refrigerant circulation and heat exchange device to actively take away the environmental heat absorbed by the ice body, so that the ice brick remains in low-temperature state in high-temperature environment. CONTENT OF THE UTILITY MODEL

[0008] The utility model provides a prevent melting ice brick, this scheme utilizes ice's higher thermal conductivity, forms efficient heat conduction channel through the close contact between pipeline and ice brick, overcomes the limitation of traditional low-temperature storage, avoids the energy consumption and system complexity problems faced by simple thermal insulation or local cooling, and provides new technical support for the application of ice products in all year and various environments.

[0009] The utility model solves the above technical problems through the following technical scheme: a prevent melting ice brick, the ice brick comprises:

[0010] Pre-fabricated ice brick, the surface is provided with a groove for installing the pipeline;

[0011] Hollow refrigerant pipeline arranged along the inside or edge of the ice brick, the refrigerant pipeline is made of metal material, and is installed in the groove of the pre-fabricated ice brick or the adjacent part thereof;

[0012] The refrigerant pipeline and the ice brick form a closed contact interface after water spraying freezing, so as to realize the heat transfer channel between the ice brick and the refrigerant pipeline;

[0013] One end of the refrigerant pipeline is connected with a heat exchange device for carrying away the heat transferred through the refrigerant pipeline.

[0014] The hollow refrigerant pipeline is made of copper, aluminum or stainless steel material to improve the heat conduction efficiency of the pipeline.

[0015] The pre-fabricated ice brick is manufactured in a low-temperature environment, and a plurality of grooves adapted to the refrigerant pipeline are formed on the surface of the pre-fabricated ice brick in advance, so as to facilitate the installation of the refrigerant pipeline and the subsequent freezing sealing formed by water spraying.

[0016] The ice brick further comprises an auxiliary device for fixing the position of the pre-fabricated ice brick and the refrigerant pipeline, which is used to ensure the close contact between the ice brick and the pipeline and improve the heat exchange effect.

[0017] The ice brick has the advantages that:

[0018] 1. By arranging the hollow refrigerant pipeline in the ice brick or on the edge and circulating the low-temperature refrigerant, the heat absorbed by the ice brick can be effectively carried away, the ice brick can be prevented from melting in a high-temperature environment, and the service life of the ice brick can be prolonged. This makes the ice product can maintain stability for a long time in a higher environment temperature, and widens the application scene of the ice product.

[0019] 2. Unlike the traditional ice product which needs to rely on low-temperature storage, cold storage or refrigerator, the ice brick is actively cooled by the internal refrigerant system, and the dependence on external low-temperature environment is avoided. In this way, the ice brick can maintain a stable state for a long time in the high-temperature south or the summer north, and breaks the limitation of season and region.

[0020] 3. By accurately controlling the temperature and flow rate of the refrigerant, it is ensured that the heat carried away by the refrigerant is greater than or equal to the heat absorbed by the ice brick, and the excess heat is discharged in time through the heat exchange device, so as to avoid the waste of energy.

Obviously, the drawings in the following description are only embodiments of the present application, and those skilled in the art can obtain other drawings according to the provided drawings without any creative effort.

[0023] Figure 1 Fig. 1 shows a structural schematic diagram of an anti-melting ice brick embodiment 1;

[0026] The following will take two embodiments and combine the drawings to more clearly and completely illustrate the present application.

[0027] The reason why ice melts is that ice absorbs heat. If ice is placed in an environment below zero degrees Celsius, such as winter in the north, an ice cabinet or a refrigerator, the ice will not melt. However, there is no effective solution if the ice is exposed to an environment above zero degrees Celsius.

[0028] The technical solution of the present application is as follows: In order to prevent ice from melting in a high-temperature environment, although it is impossible to directly control the amount of heat absorbed by ice from the surrounding environment, the heat absorbed by ice can be absorbed through a physical method. As long as the heat absorbed by ice through the physical method is greater than or equal to the heat absorbed by ice from the surrounding environment, the ice will not melt. In the present application, a hollow pipeline (the shape of the pipeline is not limited) is arranged in the interior or at the edge of the ice. The pipeline is filled with refrigerant (a liquid or gas below zero degrees Celsius). The refrigerant circulates in the pipeline and absorbs the heat of ice through the pipeline wall. The heat absorbed by ice from the surrounding environment is transferred through: ice itself - pipeline wall - refrigerant. The heat is taken away by the refrigerant, and the excess heat is replaced by a heat exchange device. The refrigerant circulates and runs according to the temperature of the environment and the temperature of the ice body, so as to control the temperature and flow rate of the refrigerant, make the heat taken away by the refrigerant greater than or equal to the heat absorbed by the ice itself, and prevent the ice from melting.

[0029] Embodiment 1: Refrigerant pipeline arranged in the interior of ice brick

[0030] 1. Ice brick pre-preparation

[0031] Mold design and size

[0032] A plastic mold with the same size as a standard building red brick is used, with the size of 240mm in length, 115mm in width, and 53mm in height. An internal channel is designed in the mold, which runs through the length of the ice brick. The diameter of the channel is set to 10mm, and the position is arranged along the center line of the 240mm long side of the ice brick, ensuring that the channel is evenly distributed in the ice brick.

[0033] Ice-making process

[0034] Pure water is injected into the mold, and a hollow copper pipe with an outer diameter of about 9mm and a suitable wall thickness is pre-placed in the channel area, ensuring that the copper pipe can be freely placed in the channel but with a suitable gap. Then the mold is placed in a low-temperature freezing device (temperature about -20℃ or lower), and after about 4 to 6 hours of freezing, an ice brick with a copper pipe inside and completely frozen water is obtained.

[0035] 2. Installation and close contact formation

[0036] Channel and pipe gap treatment

[0037] After the ice brick is taken out, a small gap may be formed between the copper pipe and the ice body due to water shrinkage during the ice-making process. At this time, a water spraying device is used to uniformly spray water along the contact area between the copper pipe and the ice body, and the low temperature of the copper pipe surface causes the sprayed water to freeze quickly, filling the gap and achieving full heat conduction contact between the copper pipe and the ice body.

[0038] Sealing and fixing

[0039] If necessary, a thin layer of ice liquid can be sprayed on the outside of the contact surface between the ice brick and the pipe, and after re-freezing, a natural bond is formed, improving the sealing and stability during long-term operation.

[0040] 3. System connection and operation

[0041] Connection of heat exchange system

[0042] The ends of the refrigerant pipe are reserved for connection, one end is connected to the multilayer semiconductor refrigeration type heat exchange device through the heat preservation pipeline, and the other end is provided with a return pipeline to form a complete refrigerant circulation system.

[0043] Refrigerant and operating parameters

[0044] The refrigerant is selected as an antifreeze for vehicles, and after being cooled by the heat exchange device, its temperature is maintained between -5℃ and -15℃; the circulation flow rate is set to meet the demand of transferring more heat than the environmental heat absorption of the ice brick per unit time.

[0045] Monitoring and adjustment

[0046] Temperature sensors can be arranged in the system (installed inside the ice brick and at the inlet and outlet of the pipe), and the refrigerant temperature and flow rate can be monitored and automatically adjusted in real time by the control unit to ensure that the temperature of the entire ice brick is maintained below the freezing point, thereby achieving the anti-melting effect.

[0047] This embodiment embeds the refrigerant pipe inside the ice brick, utilizes the high thermal conductivity of the ice body to achieve uniform heat dissipation, and ensures that the overall cooling effect of the ice brick is balanced, making it suitable for occasions where the uniformity of the internal temperature of the ice body is highly required.

[0048] Embodiment 2: Ice brick surface with refrigerant pipe

[0049] 1. Ice brick pre-fabrication

[0050] Mold design and size

[0051] A plastic mold with the same size as a standard building red brick (240mm x 115mm x 53mm) is used, and several recesses with a length of about 200mm and a depth of about 5-8mm are designed on the upper part of the mold (i.e., the outer side of the subsequent ice brick) to match the shape of the refrigerant pipe (e.g., outer diameter of 9mm) for subsequent installation.

[0052] Ice-making process

[0053] Pure water is injected into the mold to form an ice brick with pre-designed surface recesses. The pre-designed recesses are fixed on the surface of the ice body during the formation of the ice brick, and do not require subsequent processing, ensuring that the edges of the recesses are smooth and the depth is uniform.

[0054] 2. Refrigerant pipe laying

[0055] Pipe selection and installation

[0056] A stainless steel hollow refrigerant pipe made of copper or aluminum is selected, and its outer diameter matches the size of the pre-designed recess. The refrigerant pipe is laid in the recess on the surface of the ice brick according to the predetermined path, ensuring that the pipe is completely placed in the recess.

[0057] The close contact process is used to achieve close contact between the refrigerant pipe and the ice brick. Water is sprayed uniformly along the contact surface of the pipe and the recess during the laying process. The low temperature inside the pipe causes the sprayed water to freeze quickly, filling the gap between the pipe and the ice brick in the recess, thereby forming a sealed and heat-conducting interface.

[0058] Fixing method

[0059] If necessary, a thin layer of ice can be sprayed on the outside of the pipe to increase the fixing strength of the pipe and prevent the pipe from shifting or detaching from the recess due to external vibrations.

[0060] 3. System connection and operation

[0061] Pipe interface and heat exchange

[0062] The refrigerant pipe is provided with a connecting interface at both ends, one end of which is connected with the heat exchange device, and the other end serves as a return passage, forming a closed loop with the heat exchange system.

[0063] The refrigerant parameter setting selects the antifreeze for vehicles as the refrigerant, which is cooled by the heat exchange device and maintained at about -5℃ to -15℃, ensuring that it can still quickly take away the heat absorbed by the ice brick surface in a high temperature environment.

[0064] Real-time monitoring

[0065] Temperature sensors are arranged near the ice brick surface and the refrigerant pipe to monitor the temperature of the ice brick surface and the temperature at the inlet and outlet of the refrigerant pipe in real time. The automatic control system is used to adjust the flow rate and temperature of the refrigerant, achieving a sustained and stable anti-melting effect.

[0066] This embodiment uses the ice brick surface to set the refrigerant pipe, which is relatively simple in construction technology and does not need to reserve a channel inside the ice brick. It is suitable for application occasions that require to control the temperature of the ice brick surface, ensure the continuity of the appearance, and have high requirements for local cooling. At the same time, it is also convenient for local construction when maintaining and replacing the refrigerant pipe later.

[0067] Both of the above two embodiments describe the specific process steps, size parameters and key process control points in detail, and ensure that the ice brick can maintain a low temperature state in a high temperature environment from the perspective of installing the refrigerant pipe inside and on the surface, respectively, achieving the technical effect of anti-melting. In actual application, the appropriate scheme can be selected according to the project requirements and site conditions, or the optimized design can be combined with the advantages of both.
