Description

Technical Field

[0001] This utility model belongs to the field of intercoolers, and specifically relates to an adjustment structure for the inner and outer fins of an intercooler. Background Technology

[0002] When a fuel cell stack is working, hydrogen and air are introduced through different inlets. The air needs to pass through an air filter, an air compressor, an intercooler, and a humidifier in sequence before entering the stack. To increase the power generation, the air compressor needs to pressurize the gas. As the pressure increases, the gas temperature will rise, so an intercooler is required because its function is to cool the gas to the temperature required by the stack.

[0003] In existing technology, the fin structure of an intercooler includes inner fins and outer fins, with several inner and outer channels formed on the inner and outer fins respectively. The length directions of the inner and outer channels are perpendicular, and both the inner and outer channels are straight channels. The two fluids that need heat exchange pass through the inner and outer channels respectively. The disadvantages are: the heat exchange area is small, the hot and cold fluids cannot exchange heat fully, and the heat exchange efficiency is low. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable structure for the inner and outer fins of an intercooler, which can increase the heat exchange area, enable sufficient heat exchange between hot and cold fluids, and improve heat exchange efficiency.

[0005] The purpose of this utility model is achieved as follows: an adjustment structure for the inner and outer fins of an intercooler, including inner fins, wherein the inner fins include several sets of fin assemblies arranged longitudinally in sequence, each set of fin assemblies including a fin one located on the front side and a fin two located on the rear side, the fin one and fin two are arranged laterally and staggered in the lateral direction, the fin one and fin two are respectively provided with several transversely arranged channels one and channels two, the channels one and channels two are arranged longitudinally in the length direction, the corresponding channel one of the fin one is connected to the corresponding two channels two of the adjacent fin two, and the corresponding channel two of the fin two is connected to the corresponding two channels one of the adjacent fin one.

[0006] As a further improvement of this utility model, both fin one and fin two include several transversely arranged inverted U-shaped channel portions one, with a connecting portion one between each two adjacent channel portions one, and a mounting portion one at the lower end of each channel portion one on the left and right sides. Channels are formed on both the inner and outer sides of the channel portions one, and the mounting portions one facilitate the installation and fixing of fin one and fin two.

[0007] As a further improvement of this utility model, partitions are provided on both the upper and lower sides of the inner fin, and outer fins are provided on the upper side of the upper partition and the lower side of the lower partition. The outer fins are provided with several parallel transverse outer channels. The length directions of the outer channels are perpendicular to those of channel one and channel two.

[0008] As a further improvement of this utility model, the outer fin includes several longitudinally arranged inverted U-shaped channel portions II, with a connecting portion II between each adjacent channel portion II, and a mounting portion II at the lower end of each channel portion II on both the left and right sides. Channels are formed on both the inner and outer sides of the channel portions II, facilitating the installation and fixing of the outer fin through the mounting portions II.

[0009] As a further improvement of this utility model, the height ratio of the inner fin to the outer fin is (3:1) to (4:1). Reducing the wave height of the outer fin results in higher heat exchange efficiency, and the preferred height ratio of the inner to outer fin is 3.2:1.

[0010] As a further improvement of this utility model, the channel portion is provided with several protrusions, which are arc-shaped or rectangular. This increases the heat exchange area and improves the heat exchange efficiency.

[0011] As a further improvement of this utility model, the channel section is provided with a plurality of enhanced heat exchange fins. This increases the heat exchange area and improves the heat exchange rate.

[0012] In operation, the hot and cold fluids pass through the channels of the inner and outer fins, respectively. The channels of the inner and outer fins are staggered at 90° along their lengths, allowing for heat exchange between the hot and cold fluids. Compared to existing technologies, the advantages of this invention are: by designing the inner fins as serrated, the fluid sequentially passes through multiple sets of staggered channels one and two on the inner fins, moving in a meandering manner. This reduces the wave height of the outer fins, increases the number of inner and outer channels, enlarges the cross-sectional area of ​​the flow channels, and reduces the flow velocity, thereby increasing the heat exchange area, ensuring thorough heat exchange between the hot and cold fluids, and improving heat exchange efficiency.

Detailed Implementation Example 1

[0025] like Figure 1-9 As shown, an intercooler inner and outer fin adjustment structure includes an inner fin 1, which comprises several sets of fin assemblies arranged longitudinally. Each set of fin assemblies includes a fin 101 located on the front side and a fin 2 102 located on the rear side. The fin 101 and fin 2 102 are arranged laterally and are staggered laterally. The fin 101 and fin 2 102 are respectively provided with several transversely arranged channels 1 2 and channels 2 3. The channels 1 2 and channels 2 3 are arranged longitudinally in the length direction. The corresponding channel 1 2 of the fin 101 is connected to the corresponding two channels 2 3 of the adjacent fin 2 102, and the corresponding channel 2 3 of the fin 2 102 is connected to the corresponding two channels 1 2 of the adjacent fin 101.

[0026] Both fin 101 and fin 102 include several transversely arranged inverted U-shaped channel sections 4. A connecting section 5 is provided between adjacent channel sections 4, and a mounting section 6 is provided at the lower end of the channel sections 4 on both the left and right sides. Channels are formed on both the inner and outer sides of the channel sections 4, facilitating the installation and fixing of fins 101 and fin 102 via the mounting sections 6. Several enhanced heat exchange fins 11 are provided on the channel sections 4 to increase the heat exchange area and improve the heat exchange rate.

[0027] Baffles 7 are provided on both the upper and lower sides of the inner fin 1. Outer fins 8 are provided on the upper side of the upper baffle 7 and the lower side of the lower baffle 7. Several parallel transverse outer channels 9 are provided on the outer fins 8. The length direction of the outer channels 9 is perpendicular to that of channels 2 and 3. The outer fins 8 include several longitudinally arranged inverted U-shaped channel portions 8a. A connecting portion 8b is provided between two adjacent channel portions 8a. The lower ends of the channel portions 8a on both the left and right sides are provided with mounting portions 8c. Channels are formed on both the inner and outer sides of the channel portions 8a, and the mounting portions 8c facilitate the installation and fixation of the outer fins 8. The height ratio of the inner fin 1 to the outer fin 8 is (3:1) to (4:1). Reducing the wave height of the outer fin 8 results in higher heat exchange efficiency. The preferred height ratio of the inner to outer fins 8 is 3.2:1.

[0028] In operation, hot and cold fluids pass through the channels of the inner fin 1 and the outer fin 8, respectively. The channels of the inner fin 1 and the outer fin 8 are staggered along their length at 90°, allowing the hot and cold fluids to exchange heat. The advantages of this invention are: by setting the inner fin 1 in a serrated shape, the fluid passes through multiple sets of staggered channels 1 2 and 2 3 of the inner fin 1 in sequence, moving forward in a meandering manner. This reduces the wave height of the outer fin 8, increases the number of layers of inner and outer channels 9 of the inner and outer fins 8, increases the cross-sectional area of ​​the flow channels, and reduces the flow velocity, thereby increasing the heat exchange area, ensuring sufficient heat exchange between the hot and cold fluids, and improving heat exchange efficiency. Example 2

[0029] like Figure 10 The difference from Embodiment 1 is that the channel section 4 is provided with several protrusions 10, which are arc-shaped. This increases the heat exchange area and improves the heat exchange efficiency. Example 3

[0030] like Figure 11 The difference from Embodiment 1 is that the channel section 4 is provided with several protrusions 10, which are rectangular in shape. This increases the heat exchange area and improves the heat exchange efficiency.
