Description

Technical Field

[0001] This utility model relates to the field of automotive radiator technology, specifically a louvered fin structure for an automotive radiator. Background Technology

[0002] The car radiator is the core component of the vehicle's cooling system. It consists of internal porous fins, circulating water pipes, and coolant. A water pump drives the coolant to circulate between the engine and the radiator. The fins increase the heat exchange area, and the fan and natural airflow during driving quickly dissipate the heat generated by engine combustion into the air. This continuously regulates the engine temperature to a reasonable range, preventing overheating that could lead to wear, performance degradation, or malfunctions, and ensuring the safe and efficient operation of the vehicle.

[0003] Based on existing automotive radiator technology, it has been found that in environments with abundant lint and insects, a large amount of lint and insects will adhere to the radiator during vehicle operation, which can lead to radiator failure or even damage. In this case, vehicle safety cannot be guaranteed, and a lot of time needs to be spent on cleaning afterwards. Based on this, this utility model designs a louvered fin structure for automotive radiators to solve the above problems. Utility Model Content

The shielding mechanism includes a first mounting frame and a second mounting frame symmetrically arranged. The first mounting frame is mounted on the right end of the radiator body via a first fixing rod, and the second mounting frame is mounted on the left end of the radiator body via a second fixing rod. Both mounting frames contain rotating shaft assemblies. The first mounting frame contains multiple sets of vertically distributed first rotating shafts, each with a first airflow fin.

[0007] Optionally, the first mounting bracket, the first rotating shaft, and the first airflow fin are in a tilted state, while the second mounting bracket, the second rotating shaft, and the second airflow fin are in a mirror tilted state. The two airflow fin assemblies and the V-shaped guide plate together form a closed protective structure.

[0008] Optionally, the inner wall of the first connecting rod of the control mechanism is provided with a first bearing seat, which is connected to a second bearing seat on the first mounting bracket through a first cylinder body; the inner wall of the second connecting rod is provided with a third bearing seat, which is connected to a fourth bearing seat on the second mounting bracket through a second cylinder body.

[0012] Optionally, the shielding mechanism maintains an airflow channel between itself and the vehicle radiator body, with each airflow fin forming an inclined angle with the radiator body when closed and parallel to the radiator body surface when unfolded.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, a shielding mechanism is provided. The side-tilted layout of the first airflow fins and the second airflow fins, combined with the V-shaped guide plate, forms a dual protection of physical barrier and aerodynamic flow, which significantly reduces the attachment rate of mosquitoes.

A shielding mechanism 2 and an adjustment mechanism 3 are provided at the front of the automotive radiator body 1, and an electrical control box 4 is fixedly installed at the upper end of the automotive radiator body 1. The shielding mechanism 2 includes a first mounting bracket 201 and a second mounting bracket 205 symmetrically arranged. The first mounting bracket 201 is installed at the right end of the automotive radiator body 1 via a first fixing rod 202, and the second mounting bracket 205 is installed at the left end of the automotive radiator body 1 via a second fixing rod 206. Both mounting brackets are equipped with rotating shaft assemblies inside, wherein the first mounting bracket 201 is equipped with multiple sets of vertically distributed first rotating shafts 203, each first rotating shaft 203... The first airflow fin 204 is installed on the first mounting frame 201. Multiple sets of vertically distributed second rotating shafts 207 are provided inside the second mounting frame 205, and second airflow fins 208 are installed on each second rotating shaft 207. A support column 209 is provided at the connection between the first mounting frame 201 and the second mounting frame 205, and a V-shaped guide plate 210 is installed at the front end of the support column 209. The control mechanism 3 includes linkage components respectively disposed on the sides of the two airflow fins. The side of the first airflow fin 204 is connected to the first connecting rod 301 via a first rotating rod 302, and the side of the second airflow fin 208 is connected to the second connecting rod 306 via a second rotating rod 307. The electrical control box 4 drives the connecting rod to move via a cylinder assembly.

[0030] The shielding mechanism 2 adopts a symmetrical layout:

[0031] Right side component: The first fixing rod 202 fixes the first mounting bracket 201 to the right end of the heat sink body. Inside it, an array of vertically arranged first rotating shafts 203 are provided, and each shaft is welded with a first airflow fin 204 made of aluminum alloy.

[0032] Left side assembly: The second fixing rod 206 is mounted on the second mounting bracket 205, and the second rotating shaft 207 and the second airflow fins 208 are arranged in a mirror image inside.

[0033] The flow guiding structure is as follows: the two mounting brackets are connected by support columns 209, and a V-shaped flow guide plate 210 (formed by stamping stainless steel) is installed at the front end.

[0034] The telescopic end of the first cylinder body 304 is movably connected to the first bearing seat 303, and its fixed end is mounted on the first mounting bracket 201 through the second bearing seat 305; the telescopic end of the second cylinder body 309 is movably connected to the third bearing seat 308, and its fixed end is mounted on the second mounting bracket 205 through the fourth bearing seat 310.

[0035] Control mechanism 3 executes the instructions from control box 4:

[0036] Drive phase: The first cylinder 304 pulls the first connecting rod 301, which in turn drives all the first airflow fins 204 to retract through the first connecting rod 301 and the first rotating rod 302, thus achieving the closing effect.

[0037] Linkage phase: The second cylinder 309 pulls the second connecting rod 306, and controls the movement of the second airflow fins 208 through the second connecting rod 306 and the second rotating rod 307.

[0038] Closed state: The airflow fins on both sides and the guide plate 210 form a complete V-shaped protective cover.

[0039] Open state: The airflow fins are parallel to the surface of the car radiator body 1.

[0040] The working principle of this utility model is as follows: the louvered fin structure of the car radiator effectively prevents lint and insects from clogging the radiator through the coordinated action of the shielding mechanism 2 and the regulating mechanism 3. During vehicle operation, the electrical control box 4 controls the cylinder assembly according to environmental conditions: the first cylinder body 304 pushes the first connecting rod 301, which drives the first rotating rod 302 to make multiple sets of first airflow fins 204 rotate synchronously around the first rotating shaft 203; at the same time, the second cylinder body 309 pushes the second connecting rod 306, which drives the second airflow fins 208 to rotate around the second rotating shaft 207 through the second rotating rod 307. When in an environment with high lint content, the airflow fins on both sides close, forming a complete protective cover with the V-shaped guide plate 210, using its inclined surface to guide the airflow to divert foreign objects to both sides; during normal driving, the airflow fins unfold to be parallel to the car radiator body 1 to ensure heat dissipation efficiency. The support column 209 provides structural stability, the bearing seat ensures smooth transmission, and the linkage design of the rotating rod and the connecting rod realizes synchronous adjustment of multiple fins.
