Description

Technical Field

[0001] This utility model belongs to the field of heat exchange energy storage technology, and in particular relates to a solid-state multi-channel heat exchange energy storage device. Background Technology

[0002] A heat exchanger is a device that transfers heat from one fluid to another. Multi-channel heat exchange and energy storage devices are suitable for equipment such as chiller water tank heat exchangers, air conditioning heat exchangers, air conditioning evaporator heat exchangers, chemical heat exchangers, food processing heat exchangers, and power industry heat exchangers.

[0003] Current heat exchange energy storage devices employ liquid heat conduction technology. However, this technology is limited by the high-temperature boiling and vaporization of the liquid, as well as its freezing point. Liquid boiling causes molecules to evaporate into the atmosphere, leading to air pollution, while freezing can cause pipes to expand and rupture. Liquid leaks are also prone to occur during use and transportation, resulting in heat loss. Furthermore, using liquid heat conduction technology in heat exchange energy storage devices requires the installation of additional pipe replenishment systems, further complicating the structure. Summary of the Invention

[0004] The technical problem to be solved by this invention is to overcome the defects of the prior art and to solve the problem that the heat exchange effect of existing heat exchange energy storage devices is easily affected by temperature changes.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a solid-state multi-channel heat exchange energy storage device, including a shell, a second heat-conducting tube body arranged in a spiral shape is provided inside the shell, a first heat-conducting tube body is provided inside the second heat-conducting tube body, and a heat-conducting sleeve is fitted into the inner wall of the first heat-conducting tube body.

[0006] A heat-conducting block is provided between the first heat-conducting pipe body and the second heat-conducting pipe body. A central cavity is opened in the middle of the heat-conducting block, and the heat-conducting sleeve and the first heat-conducting pipe body are placed inside the central cavity.

[0007] In the preferred embodiment of this utility model, the first heat pipe body, the second heat pipe body, and the heat-conducting block are made of solid metals such as copper, iron, aluminum, lead, and tin.

[0008] In a preferred embodiment of this invention, rectangular grooves are provided around both the upper and lower ends of the heat-conducting block, and an elastic sealing frame that is tightly attached to the surface of the second heat-conducting tube is embedded inside the groove.

[0009] In a preferred embodiment of this utility model, the first heat-conducting tube and the second heat-conducting tube extend outward from either end of the housing. A through groove is provided in the middle of the upper end of the housing, positioned directly above the heat-conducting sleeve. The through groove is located between the first heat-conducting tube and the second heat-conducting tube.

[0010] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0011] The heat-conducting block fills the gap between the first heat-conducting tube body and the second heat-conducting tube body, thereby enhancing the stability and thermal conductivity of the first heat-conducting tube body and the second heat-conducting tube body when they are assembled together inside the shell.

[0012] This heat exchange energy storage device uses solid metal heat exchange technology to replace the existing liquid heat exchange technology. Compared with the original technology, this technology makes up for the defect that the heat exchange effect changes due to changes in liquid state.

[0013] Solid metals offer superior and faster thermal conductivity, have a simple structure, and are less prone to volatilization and secondary pollution. Liquid leakage is not a concern during handling and transportation. Their exchange temperature can far exceed the boiling point of liquids, and their lower limit for low-temperature heat exchange is even lower. The absence of liquid eliminates concerns about the destructive power of freezing. They boast higher exchange efficiency and a wider temperature range, enabling energy storage and release functions similar to liquids. This reduces the volumetric burden of heat exchange, resulting in higher efficiency. They overcome the limitations of high and low temperature heat transfer, have a simple structure, and are less prone to volatilization and secondary pollution. The absence of evaporation eliminates the need for complex protective devices and accessories, minimizing costs associated with accessories and reducing subsequent maintenance and upkeep costs.

[0022] Please see Figure 1-7This utility model provides a technical solution: a solid-state multi-channel heat exchange energy storage device, including a shell 1, inside which a second heat-conducting pipe body 5 is arranged in a spiral pattern, and a first heat-conducting pipe body 4 is arranged inside the second heat-conducting pipe body 5, with a heat-conducting sleeve 3 fitted into the inner wall of the first heat-conducting pipe body 4; a heat-conducting block 6 is arranged between the first heat-conducting pipe body 4 and the second heat-conducting pipe body 5, and a central cavity 9 is opened in the middle of the heat-conducting block 6, with the heat-conducting sleeve 3 and the first heat-conducting pipe body 4 placed inside the central cavity 9; the first heat-conducting pipe body 4 and the second heat-conducting pipe body 5... The first and second heat-conducting tubes extend outward from either end of the housing 1. A through groove 2 is located in the middle of the upper end of the housing 1, directly above the heat-conducting sleeve 3. The through groove 2 is positioned between the first heat-conducting tube 4 and the second heat-conducting tube 5. The first heat-conducting tube 4 and the second heat-conducting tube 5 are arranged in a spiral shape inside the same housing 1. The first and second heat-conducting tubes 4 and 5 extend upward from both ends of the upper end of the housing 1 to connect with external equipment. The inside of the through groove 2 is filled with a mixture of highly thermally conductive solid metals such as copper, iron, aluminum, lead, and tin. The heat is transferred to the interior of the shell 1 through the first heat-conducting pipe 4 to enhance the thermal conductivity of the shell 1. The heat generated by the external equipment is transferred to the interior of the shell 1 through the first heat-conducting pipe 4. The heat comes into contact with the heat-conducting sleeve 3 at the spiral part of the first heat-conducting pipe 4. The heat-conducting sleeve 3 can both support and reinforce the tubular busbar cylindrical structure formed by the interconnected spiral parts of the first heat-conducting pipe 4, and concentrate the heat transferred to the spiral part of the first heat-conducting pipe 4. The materials of the first heat-conducting pipe 4, the second heat-conducting pipe 5, and the heat-conducting block 6 are copper, iron, aluminum, lead, and tin. The heat-conducting block 6 is made of copper casting. Since the second heat-conducting tube 5 originally had no heat, there is a temperature difference between the second heat-conducting tube 5 and the first heat-conducting tube 4. Heat will be transferred from the first heat-conducting tube 4 to the second heat-conducting tube 5. The heat is transferred from the first heat-conducting tube 4 through the heat-conducting block 6 and the heat is concentrated on the surface of the heat-conducting block 6. The temperature of the heat-conducting block 6 is higher than the temperature of the second heat-conducting tube 5. Heat is transferred from the heat-conducting block 6 to the second heat-conducting tube 5 and then from the second heat-conducting tube 5 to other external devices to achieve the heat exchange effect.The heat-conducting block 6 has a central cavity 9 that can accommodate the heat-conducting sleeve 3 and the first heat-conducting tube 4. The heat-conducting sleeve 3 ensures that the spiral portion of the first heat-conducting tube 4 is tightly attached to the inner wall of the central cavity 9. The outer periphery of the heat-conducting block 6 contacts the spiral portion of the second heat-conducting tube 5. Rectangular grooves 8 are formed around both the upper and lower ends of the heat-conducting block 6. An elastic sealing frame 7, which is tightly attached to the surface of the second heat-conducting tube 5, is embedded inside the groove 8. (The shape of the groove 8 is consistent with and matches the shape of the elastic sealing frame 7.) The annular groove 8 can embed the elastic sealing frame 7 between the upper and lower ends of the heat-conducting block 6 and the inner side of the spiral portion of the second heat-conducting tube 5. The elastic sealing frame 7 allows the heat-conducting block 6 to conduct heat through the spiral portion of the second heat-conducting tube 5. The heat block 6 can fit more tightly into the inner side of the spiral part of the second heat-conducting tube 5. The heat-conducting sleeve 3 and the first heat-conducting tube 4 are placed inside the central cavity 9 and can maintain a distance from the second heat-conducting tube 5. The heat-conducting block 6 allows the first heat-conducting tube 4 and the second heat-conducting tube 5 to be assembled with a distance between them. The heat-conducting block 6 fills the gap between the first heat-conducting tube 4 and the second heat-conducting tube 5. The heat-conducting block 6 enhances the stability and thermal conductivity of the first heat-conducting tube 4 and the second heat-conducting tube 5 assembled inside the shell 1. The heat-conducting block 6 can enhance the heat exchange effect between the first heat-conducting tube 4 and the second heat-conducting tube 5.

[0023] This heat exchange energy storage device uses solid metal heat exchange technology to replace the existing liquid heat exchange technology. The first heat-conducting pipe 4 and the second heat-conducting pipe 5 form multiple heat exchange paths inside the shell. The first heat-conducting pipe 4 and the second heat-conducting pipe 5 can exchange heat by switching directions. The solid metal uses copper with good thermal conductivity as the heat transfer medium (copper surface electroplated protective layer). By using solid metal instead of liquid metal as the heat transfer medium, the shape of solid metal is less affected by temperature changes, the exchange temperature can be far higher than the boiling temperature of liquid, and the lower limit of the low temperature of heat exchange is lower. Solid metal has no liquid flow, so there is no need to consider the destructive force caused by freezing, eliminating the impact of temperature changes, and it is not easy to volatilize and cause secondary pollution. There is no need to consider the problem of liquid leakage during handling and transportation.

[0024] Solid metals offer superior and faster thermal conductivity, a simpler structure, higher exchange efficiency, and a wider temperature range. They can perform energy production, storage, and release functions similar to liquids. They also facilitate the design of multiple heat exchange paths, overcoming the limitations of high and low temperature heat transfer. Their simple structure prevents evaporation and secondary pollution. The solid metal form is unaffected by temperature changes, reducing the volumetric weight of heat exchange and increasing efficiency. They eliminate the need to consider evaporation and avoid the need for complex protective devices and accessories, minimizing costs associated with accessories and reducing subsequent maintenance costs.

[0025] Compared with the original technology, this technology makes up for the defect that the heat exchange effect changes due to changes in liquid state.
