The non-uniform fin imitating the streamline shape of the sword fish is formed by arranging two different sword fish imitating fins in a staggered mode. Through differentiated design of structural parameters of the two sword-like fins, flow resistance is reduced through sparse arrangement of the fins in the front half section and the streamline shape of the sword-like fins, and heat exchange efficiency is improved through dense arrangement and staggered arrangement of the fins in the rear half section.

Description

Technical Field

[0001] This invention relates to the field of cooling equipment technology, and in particular to a non-uniform fin structure with a streamlined shape resembling a swordfish. Background Technology

[0002] Conventional plate-fin radiators achieve efficient gas-liquid heat exchange through their staggered fin structure. Their compact, lightweight, and high specific surface area characteristics make them widely used in various subsystems of vehicle thermal management, such as engine cooling systems, oil coolers, intercoolers, new energy vehicle battery cooling, and integrated controller cooling modules.

[0003] Due to the compact design of automotive interiors, plate-fin radiators must meet both the vehicle's internal heat dissipation requirements and the constraints of internal airflow resistance. Common fin structures for plate-fin heat exchangers include cylindrical, semi-circular, square, and S-shaped fins, which enhance the heat transfer surface. However, while enhancing heat transfer, these structures significantly increase flow resistance losses within the channels. Therefore, researching new structures that can reduce flow resistance while maintaining heat transfer performance is essential for automotive plate-fin heat exchangers. Summary of the Invention

[0004] The purpose of this invention is to provide a non-uniform fin structure with a streamlined shape resembling a swordfish, which solves the problem that it is difficult to balance heat dissipation performance and airflow resistance requirements in a compact space for vehicle radiators.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This invention provides a non-uniform fin structure with a streamlined shape resembling a swordfish, comprising at least two flow channel baffles and swordfish-shaped fins arranged alternately between two opposite flow channel baffles; The swordfish-like fins include sparsely arranged fins and densely arranged fins; the offset between adjacent swordfish-like fins is 20%-50%; the offset between adjacent sparsely arranged fins is no greater than the offset between adjacent densely arranged fins.

[0006] In this embodiment, both the sparsely arranged fins and the densely arranged fins are streamlined structures, and both include a streamlined head and a variable cross-section body structure.

[0007] Furthermore in this embodiment, the maximum thickness of the sparsely arranged fins is less than the maximum thickness of the densely arranged fins.

[0008] Furthermore in this embodiment, the maximum thickness of the sparsely arranged fins and the maximum thickness of the densely arranged fins are both located at approximately 1 / 4 to 1 / 3 of the length of the streamlined head.

[0009] Furthermore, in this embodiment, the thickness of the imitation swordfish fin is 0.2-0.4 mm.

[0010] Furthermore in this embodiment, the spacing between adjacent sparsely arranged fins in the thickness direction is smaller than the spacing between adjacent densely arranged fins in the thickness direction.

[0011] Furthermore, in this embodiment, the spacing between adjacent swordfish-like fins is 1.2-2.2 mm.

[0012] Furthermore, in this embodiment, the length of the imitation swordfish fin is 5mm.

[0013] Furthermore, in this embodiment, the thickness of the flow channel baffle is 0.5 mm.

[0014] This embodiment provides a radiator, which includes a housing and a plurality of heat dissipation fins disposed within the housing, wherein the heat dissipation fins are the aforementioned swordfish-inspired fins.

[0015] Compared with the prior art, the beneficial technical effects of the present invention are as follows: The non-uniform fins with a swordfish-like streamlined shape in this invention are formed by two different swordfish-like fins arranged in an alternating manner. Through the differentiated design of the structural parameters of these two swordfish-like fins, the sparse arrangement of the fins in the front half and the swordfish-like streamlined shape reduce flow resistance, while the dense arrangement and alternating arrangement of the fins in the rear half improve heat exchange efficiency.

[0017] Explanation of reference numerals in the attached figures: 1-Flow plate partition, 2-Sparse section with fins, 3-Dense section with fins. Detailed Implementation

[0018] refer to Figure 1This embodiment discloses a non-uniform fin structure with a streamlined shape resembling a swordfish, comprising a flow channel baffle 1 and multiple swordfish-shaped fins connecting two opposing flow channel baffles 1; wherein the swordfish-shaped fins include two different arrangements: sparsely arranged fins 2 and densely arranged fins 3. The sparsely arranged fins 2 are located upstream of the air inflow, and the densely arranged fins 3 are located downstream of the air inflow.

[0019] In practical applications, non-uniform fin structures can be used in automotive radiators to meet the vehicle's internal heat dissipation requirements, while also taking into account the requirements for internal airflow resistance, and they also have high compactness.

[0020] refer to Figure 1 and Figure 3 The two parallel imitation swordfish fins form a group, and each group is arranged between two opposing flow channel baffles 1 in a staggered manner with the adjacent group of imitation swordfish fins. In specific applications, depending on the scenario, three or N parallel imitation swordfish fins can also be grouped together.

[0021] refer to Figure 2 The length L of the two types of single-piece swordfish fins mentioned above is uniformly distributed along the flow direction.

[0022] refer to Figure 3 and Figure 4 The non-uniform fin structure consists of two types of swordfish-like fins with different thicknesses δ, spacing W, and offset W1 / W.

[0023] Note: Length L is the distance from the streamlined head to the tail; δ is the maximum thickness; W is the distance between the center lines of the two swordfish-like fins; W1 is the distance between the tail end and the center line of the adjacent swordfish-like fin.

[0024] The two swordfish fin-like structural parameters in this embodiment are as follows: The sparsely arranged fins 2 have a thickness of 0.3 mm, a spacing of 2.2 mm, and a stagger of 35%.

[0025] The thickness of the densely arranged fins 3 is 0.4 mm, the spacing is 1.7 mm, the stagger is 50%, and the length of both types of fins is 5 mm.

[0026] The non-uniform structure of the two biomimetic fin combinations used in this embodiment is compared with the simulation results of fins 2 with only sparse sections and fins 3 with only dense sections. The non-uniform fins achieved better heat transfer performance and lower flow resistance, as detailed in Table 1:

[0027] The non-uniform fin structure with a swordfish-like streamlined shape of the present invention consists of two different swordfish-like fins arranged in an alternating pattern. Through the differentiated design of the structural parameters of these two swordfish-like fins, the sparse arrangement of the fins and the swordfish-like streamlined shape in the front half reduce flow resistance, while the dense arrangement and alternating pattern of the fins in the rear half improves heat exchange efficiency. This solves the problem of vehicle radiators struggling to balance heat dissipation performance and airflow resistance requirements in a compact space.

[0028] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
