Description

Technical Field

[0001] This invention patent relates to the field of channel cooling plates, and more particularly to a spider web-shaped channel cooling plate for energy storage. Background Technology

[0002] Cooling plates are commonly used in electronic devices, automotive engines, and industrial machinery to maintain the normal operating temperature of the equipment and prevent overheating damage. The working principle of cooling plates is based on heat conduction and convection heat dissipation. Channel cooling plates should also be used to cool battery modules.

[0003] The existing channel cooling plates, which do not use a spider web-like cooling plate, have poor heat dissipation effect. The overall temperature distribution of the coolant is uneven, and the surface temperature difference is large, which will cause the overall heat dissipation of the entire energy storage battery module to fail to meet the requirements, and the heat exchange efficiency between the cooling plate and the battery module is low.

[0004] Therefore, it is necessary to provide a spider web-shaped channel cooling plate for energy storage to solve the above-mentioned technical problems. The information disclosed in this background section is only intended to enhance the understanding of the overall background of the present invention, and is not necessarily to be regarded as an admission or in any way implying that the information constitutes prior art that has become known to those skilled in the art.

[0005] Invention Patent Content

[0006] This invention patent provides a spider web-shaped channel cooling plate for energy storage, which solves the technical problems of poor heat dissipation, uneven temperature distribution of the coolant, large surface temperature difference, and failure of the entire energy storage battery module to meet the heat dissipation requirements when the cooling plate is not spider web-shaped, and low heat exchange efficiency between the cooling plate and the battery module.

[0007] To solve the above-mentioned technical problems, this invention provides a spider web-like channel cooling plate for energy storage, comprising a cooling substrate and cooling pipes. The cooling pipes are disposed on the front side of the cooling substrate. One side of the cooling pipe, located at the top left side of the front side of the cooling substrate, is a water inlet pipe, and the other side of the cooling pipe, located at the bottom left side of the front side of the cooling substrate, is a water outlet pipe. The cooling pipes include an alloy substrate layer, a reinforcing layer is disposed on the outer surface of the alloy substrate layer, an outer surface layer is disposed on the outer surface of the reinforcing layer, and the outer surface layer is an electroplated corrosion-resistant material layer. The inner surface of the alloy substrate layer is disposed of a corrosion-resistant layer, which includes an anti-oxidation alloy layer. The outer surface of the anti-oxidation alloy layer is disposed of a nickel alloy layer, and the outer surface of the nickel alloy layer is disposed of a corrosion-resistant oxide film layer.

[0008] Preferably, the reinforcing layer includes a steel alloy layer, and a copper alloy layer is disposed on the outer surface of the steel alloy layer.

[0009] Preferably, the outer surface of the corrosion-resistant layer is bonded to the inner surface of the alloy substrate layer, and the thickness of the corrosion-resistant layer is the same as the thickness of the outer surface layer.

[0010] Preferably, the diameter of the cooling pipe is 7mm, the spacing between the cooling pipe channels is 16mm, and the thickness of the cooling substrate is 12mm.

[0011] Preferably, the diameter of the inlet pipe and the diameter of the outlet pipe are the same, and the diameter of the inlet pipe is 7mm.

[0012] Preferably, the outer surface of the alloy substrate layer is bonded to the inner surface of the reinforcing layer, and the outer surface of the reinforcing layer is bonded to the inner surface of the outer surface layer.

[0013] Preferably, the outer surface of the steel alloy layer is bonded to the inner surface of the copper alloy layer.

[0014] Preferably, the outer surface of the antioxidant alloy layer is bonded to the inner surface of the nickel alloy layer, and the outer surface of the nickel alloy layer is bonded to the inner surface of the corrosion-resistant oxide film layer.

[0015] Compared with related technologies, the spiderweb-shaped channel cooling plate for energy storage provided by this invention patent has the following beneficial effects:

[0016] This invention patent provides a spiderweb-shaped channel cooling plate for energy storage. When the diameter of the cooling pipes is 7mm, the thickness of the cooling substrate is 12mm, and the spacing between the cooling pipe channels is 16mm, the heat exchange effect between the cooling substrate and the external battery module requiring cooling is optimal. The maximum temperature and temperature difference of the external battery module requiring cooling decrease with increasing diameter, spacing, and thickness. Through a reasonable layout, the cooling channels of the cooling substrate and cooling pipes are designed in a spiderweb shape, resulting in more efficient and energy-saving heat exchange between the cooling substrate and the external battery pack. The maximum temperature and temperature difference of the external battery module are lower, but the pressure drop in the cooling pipe channels is slightly lower and higher. The flow direction of the coolant in the cooling pipes has a significant impact on the heat dissipation of the battery module. A more uniform overall temperature distribution in the direction of the coolant flow results in a smaller temperature difference on the surface of the cooling substrate, leading to better overall heat dissipation of the battery module. This solves the technical problems of poor heat dissipation when not using a spiderweb-shaped cooling plate, where uneven overall temperature distribution in the direction of the coolant flow and large surface temperature differences cause the overall heat dissipation of the energy storage battery module to fail to meet requirements, and low heat exchange efficiency between the cooling plate and the battery module.

[0017] This invention patent provides a spiderweb-shaped channel cooling plate for energy storage, which employs a corrosion-resistant layer, an anti-oxidation alloy layer, a nickel alloy layer, and a corrosion-resistant oxide film layer. It exhibits exceptionally good physical properties, including good ductility, high hardness, attractive color, corrosion resistance, and deep-drawing performance. It is widely used in shipbuilding, petrochemicals, electrical appliances, instruments, medical machinery, daily necessities, and handicrafts. Its strong corrosion resistance extends the corrosion resistance and service life of the cooling pipe, solving the leakage problem caused by corrosion in traditional cooling pipes. Through the addition of reinforcing layers, steel alloy layers, and copper alloy layers, it possesses advantages such as high strength, high hardness, and strong chemical corrosion resistance, increasing the strength and corrosion resistance of the cooling pipe and further extending its service life. Even in harsh environments, it significantly enhances the strength of the cooling pipe. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0025] Example 1:

[0026] Please see Figure 1-5This invention patent provides a technical solution: a spider web-shaped channel cooling plate for energy storage, including a cooling substrate 1 and a cooling pipe 2. The cooling pipe 2 is disposed on the front side of the cooling substrate 1. One side of the cooling pipe 2 and located at the top left side of the front side of the cooling substrate 1 is a water inlet pipe 3, and the other side of the cooling pipe 2 and located at the bottom left side of the front side of the cooling substrate 1 is a water outlet pipe 4. The cooling pipe 2 includes an alloy substrate layer 5. A reinforcing layer 6 is disposed on the outer surface of the alloy substrate layer 5. An outer surface layer 7 is disposed on the outer surface of the reinforcing layer 6. The outer surface layer 7 is an electroplated corrosion-resistant material layer. A corrosion-resistant layer 8 is disposed on the inner surface of the alloy substrate layer 5. The corrosion-resistant layer 8 includes an anti-oxidation alloy layer 81. A nickel alloy layer 82 is disposed on the outer surface of the anti-oxidation alloy layer 81. A corrosion-resistant oxide film layer 83 is disposed on the outer surface of the nickel alloy layer 82.

[0027] In this implementation scheme, when the diameter of the cooling pipe 2 is 7mm, the thickness of the cooling substrate 1 is 12mm, and the channel spacing of the cooling pipe 2 is 16mm, the heat exchange effect between the cooling substrate 1 and the external battery module requiring cooling is optimal. The maximum temperature and temperature difference of the external battery module requiring cooling decrease with the increase of diameter, spacing, and thickness. Through reasonable layout, the cooling channels of the cooling substrate 1 and the cooling pipe 2 are designed in a spider web shape, which makes the heat exchange efficiency between the cooling substrate 1 and the external battery pack more efficient and energy-saving. The maximum temperature and temperature difference of the external battery module are lower, but the pressure drop of the cooling pipe 2 channel is slightly lower and higher. The flow direction of the coolant in the cooling pipe 2 has an important impact on the heat dissipation of the battery module. The overall temperature distribution of the coolant flowing towards the coolant is more uniform, the surface temperature difference of the cooling substrate 1 is smaller, and the overall heat dissipation of the battery module is better. This solves the technical problems of poor heat dissipation when not using a spider web-shaped cooling plate, where the overall temperature distribution of the coolant flowing towards the coolant is uneven, the surface temperature difference is large, and the overall heat dissipation of the entire energy storage battery module fails to meet the requirements, resulting in low heat exchange efficiency between the cooling plate and the battery module.

[0028] Example 2:

[0029] Please see Figure 1-5As shown, based on Embodiment 1, this invention provides a technical solution: the reinforcing layer 6 includes a steel alloy layer 61, a copper alloy layer 62 is disposed on the outer surface of the steel alloy layer 61, the outer surface of the corrosion-resistant layer 8 is bonded to the inner surface of the alloy substrate layer 5, the thickness of the corrosion-resistant layer 8 is the same as the thickness of the outer surface layer 7, the diameter of the cooling pipe 2 is 7mm, the channel spacing of the cooling pipe 2 is 16mm, the thickness of the cooling substrate 1 is 12mm, the diameter of the water inlet pipe 3 is the same as the diameter of the water outlet pipe 4, the diameter of the water inlet pipe 3 is 7mm, the outer surface of the alloy substrate layer 5 is bonded to the inner surface of the reinforcing layer 6, the outer surface of the reinforcing layer 6 is bonded to the inner surface of the outer surface layer 7, the outer surface of the steel alloy layer 61 is bonded to the inner surface of the copper alloy layer 62, the outer surface of the anti-oxidation alloy layer 81 is bonded to the inner surface of the nickel alloy layer 82, and the outer surface of the nickel alloy layer 82 is bonded to the inner surface of the corrosion-resistant oxide film layer 83.

[0030] In this embodiment, the use of a corrosion-resistant layer 8, an anti-oxidation alloy layer 81, a nickel alloy layer 82, and a corrosion-resistant oxide film layer 83 results in exceptionally good physical properties, including good ductility, high hardness, attractive color, corrosion resistance, and deep-drawing performance. It is widely used in shipbuilding, petrochemicals, electrical appliances, instruments, medical machinery, daily necessities, and handicrafts, exhibiting strong corrosion resistance, extending the corrosion resistance and service life of the cooling pipe 2, and solving the problem of leakage caused by corrosion in traditional cooling pipes 2. Furthermore, the use of a reinforcing layer 6, a steel alloy layer 61, and a copper alloy layer 62 provides advantages such as high strength, high hardness, and strong chemical corrosion resistance, increasing the strength and corrosion resistance of the cooling pipe 2, further extending its service life, and significantly increasing its strength even in harsh environments.

[0031] The working principle of the spider web-shaped channel cooling plate for energy storage provided by this invention patent is as follows:

[0032] Implementation steps for the first innovation point:

[0033] Step 1: When the diameter of cooling pipe 2 is 7mm, the thickness of cooling substrate 1 is 12mm, and the channel spacing of cooling pipe 2 is 16mm, the heat exchange effect between cooling substrate 1 and the peripheral battery module that needs to be cooled is optimal. The maximum temperature and temperature difference of the peripheral battery module that needs to be cooled decrease as the diameter, spacing and thickness increase.

[0034] Step 2: Through reasonable layout, the cooling channels of cooling substrate 1 and cooling pipe 2 are designed in a spider web pattern. The heat exchange efficiency between cooling substrate 1 and external battery pack is more efficient and energy-saving, and the maximum temperature and temperature difference of external battery module are lower. However, the pressure drop of cooling pipe 2 is slightly lower and higher. The flow direction of coolant in cooling pipe 2 has an important impact on the heat dissipation of battery module. The overall temperature distribution of the flowing coolant is more uniform, the surface temperature difference of cooling substrate 1 is smaller, and the overall heat dissipation of battery module is better. This solves the technical problems of poor heat dissipation effect when not using a spider web-shaped cooling plate, where the overall temperature distribution of the flowing coolant is uneven and the surface temperature difference is large, which will cause the overall heat dissipation of the entire energy storage battery module to fail to meet the requirements and the heat exchange efficiency between cooling plate and battery module is low.

[0035] Implementation steps for the second innovation point:

[0036] Step 1: The design incorporates a corrosion-resistant layer 8, an anti-oxidation alloy layer 81, a nickel alloy layer 82, and a corrosion-resistant oxide film layer 83. These layers exhibit exceptionally good physical properties, including excellent ductility, high hardness, attractive color, and strong corrosion resistance and deep-drawing performance. They are widely used in shipbuilding, petrochemicals, electrical appliances, instruments, medical machinery, daily necessities, and handicrafts. This design provides strong corrosion resistance, extends the corrosion resistance and service life of the cooling pipe 2, and solves the problem of leakage caused by corrosion in traditional cooling pipes 2.

[0037] The second step: By setting up the reinforcing layer 6, the steel alloy layer 61 and the copper alloy layer 62, it has the advantages of high strength, high hardness and strong chemical corrosion resistance, which increases the strength and corrosion resistance of the cooling pipe 2 and further extends the service life of the cooling pipe 2. Even in harsh environments, it greatly increases the strength of the cooling pipe 2.
