Description
Technical Field
[0001] The present application belongs to the field of automobile auxiliary tools, and specifically relates to a wind shield with an air guide structure and an engine heat dissipation device. Background Art
[0002] At present, the cooling system of water-cooled engines in fuel-powered vehicles uses a vertical water tank with a heat pipe and heat belt structure, combined with the engine's own cooling fan or electronic fan to cool the coolant circulating between the engine water channel and the radiator, so that the engine can always maintain a reasonable temperature range and allow the engine to operate stably.
[0003] Since the effective working area of the fan is disc-shaped when it rotates, and the radiator mostly adopts a vertical rectangular shape, a wind shield must be designed to collect all the hot air that penetrates the radiator and pass through the engine fan to ensure the effective heat dissipation of the radiator.
[0004] Traditional wind shields are mostly sheet structures, with one side connected to the rectangular radiator and the other side connected to the circular engine fan. This structure makes it more difficult for the hot air at the four corners of the radiator to be discharged from the cooling system than the area where the fan sweeps the radiator. In addition, the rotating airflow caused by the high-speed rotation of the fan is prone to turbulence at the four corners of the radiator, which brings additional resistance, noise and vibration.
[0005] To this end, a wind shield with an air guide structure is designed to effectively improve the heat dissipation efficiency of traditional radiators and reduce wind noise and vibration. Utility Model Content
[0006] The present application provides a wind shield with an air guide structure, which solves the problem in the prior art that hot air escapes when flowing through the radiator to the engine fan, and the hot air is difficult to be discharged at the four corners of the radiator, resulting in low heat dissipation efficiency. In addition, turbulence occurs under the influence of the rotating airflow caused by the high-speed rotation of the engine fan, resulting in large vibration and noise during the operation of the radiator.

[0010] As a preferred embodiment, the wind gathering piece extends from the edge of the guard plate toward the center and the width gradually increases. The extension direction of the wind gathering piece is the same as the rotation direction of the blades of the engine fan.
[0011] As a preferred embodiment, the guard plate includes a plurality of splicing plates, and the plurality of splicing plates are connected end to end to enclose and form the guard plate, and each splicing plate is provided with a wind gathering piece.

[0013] As a preferred embodiment, the guard plate is integrally formed and is provided with a plurality of wind gathering pieces.
[0014] As a preferred embodiment, the wind collecting piece and the guard plate are integrally formed.
[0015] Alternatively, the wind gathering piece and the guard plate are formed separately.
[0016] As a preferred embodiment, the guard plate protrudes from the first mounting portion to the second mounting portion, and the radiator, guard plate and engine fan are surrounded to form an assembly gap between the engine fan and the radiator, and an annular airflow is formed in the assembly gap, flowing circumferentially along the first mounting portion, and the gas at the assembly gap converges into the annular airflow at the assembly gap along the wind gathering plate.

[0018] This solution also includes: an engine cooling device, including a radiator and a fan, and a wind shield as described above is arranged between the radiator and the fan.
[0019] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:
[0020] (1) By setting an air guide channel between the wind shield and the radiator, the gas in the assembly gap, that is, the hot air passing through the radiator, is collected and concentrated through the air guide channel, so that the hot air flows to the engine fan, thereby preventing the hot air from escaping to the corners in the assembly gap and becoming difficult to discharge, thereby improving the heat dissipation efficiency of the radiator, and preventing the hot air from escaping to the corners of the assembly gap and being affected by the high-speed rotation of the engine fan to cause turbulence, thereby avoiding noise and vibration caused by turbulence during the operation of the radiator.

[0034] The present application provides a wind shield 3 with a wind guide structure and an engine heat dissipation device, such as Figures 1 to 4 As shown, the wind shield 3 is located between the engine fan 2 and the radiator 1. The wind shield 3 includes a first mounting portion 31 connected to the radiator 1 and a second mounting portion 32 connected to the engine fan 2, and a guard plate 33 arranged between the first mounting portion 31 and the second mounting portion 32. An assembly gap is provided between the engine fan 2 and the radiator 1, and an air guide channel is provided on the side of the guard plate 33 facing the radiator 1. The gas at the assembly gap flows to the engine fan 2 along the air guide channel.
[0035] First, the starting point of this solution is explained: the radiator 1 is rectangular in shape. In order to match the circular engine fan 2, a wind shield 3 device needs to be designed between the radiator 1 and the engine fan 2. Since the two ends of the wind shield 3 need to complete a smooth transition between the rectangle and the circle, a large assembly gap is formed between the radiator 1 and the engine fan 2; cold air enters from one side of the radiator 1, and the hot air escaping from the other side after passing through the radiator 1 is driven by the rotation of the blades of the engine fan 2. The airflow in the wind shield 3 will form a circular airflow. The high-temperature gas flowing out from the four corners of the radiator 1 can easily form turbulence before reaching the fan under the action of the circular airflow, thereby causing the radiator 1 to have large noise and vibration during operation. Since there is no guide structure design at the four right angles of the radiator 1, the hot air in the corners is not easy to dissipate.
[0036] The present application scheme arranges an air guide channel between the wind shield 3 and the radiator 1, and collects the gas in the assembly gap, that is, the hot air passing through the radiator 1, through the air guide channel, so that the hot air flows to the engine fan 2, thereby preventing the hot air from escaping to the corners in the assembly gap and becoming difficult to discharge, thereby improving the heat dissipation efficiency of the radiator 1, and preventing the hot air from escaping to the corners of the assembly gap and being affected by the high-speed rotation of the engine fan 2 to cause turbulence, thereby avoiding noise and vibration caused by turbulence during the operation of the radiator 1.
[0037] In addition, the wind shield 3 can be made of an integrally formed plastic material, or can be made of a metal material by multi-faceted welding.
[0038] In one embodiment, the guard plate 33 is provided with an air gathering piece 4, which is arc-shaped, and its inner side surface faces the center of the guard plate 33. The air gathering piece 4 includes a positioning end 41 located on the guard plate 33, and extends along the positioning end 41 toward the radiator 1, and its extended end forms a raised end 42. The air gathering piece 4, the radiator 1 and the guard plate 33 are enclosed to form an air guide channel.
[0039] The wind collecting piece 4 has a simple structure and low cost, and is located on the guard plate 33 without taking up extra space, and can be enclosed with the radiator 1 and the guard plate 33 to achieve a wind guiding effect.
[0040] It should be noted that, in the enclosure described here, the wind collecting piece 4 is not in contact with the radiator 1 , but since the wind collecting piece 4 is arc-shaped, it can form a wind guiding effect in terms of its positional relationship with the radiator 1 .
[0041] Furthermore, the wind gathering pieces 4 extend from the edge of the guard plate 33 toward the center and their width gradually increases. The extending direction of the wind gathering pieces 4 is the same as the rotation direction of the blades of the engine fan 2 .
[0042] Since the width of the wind-collecting sheet 4 gradually increases from the edge of the guard plate 33 to the middle, and its extension direction is the same as the rotation direction of the blades of the engine fan 2, on the one hand, it is beneficial to form a shield for the corners and reduce the escape of gas to the corners. On the other hand, it is beneficial to guide and converge the hot air passing through the radiator 1 along the airflow direction formed by the engine fan 2, and guide the airflow to the center, thereby improving the hot air exhaust efficiency.
[0043] The guard plate 33 can be in various forms, and the following embodiments may be referred to for details:
[0044] Embodiment 1: The guard plate 33 includes a plurality of splicing plates 34 , and the plurality of splicing plates 34 are connected end to end to enclose and form the guard plate 33 , and each splicing plate 34 is provided with a wind gathering piece 4 .
[0045] The processing difficulty is low, the molding method is simple, and each splicing plate 34 is provided with a wind gathering piece 4, which is conducive to enhancing the wind guiding effect.
[0046] Preferably, the splicing plates 34 are four triangular plates, which are connected end to end to make the guard plate 33 rectangular. The wind collecting pieces 4 are located at the corners of the guard plate 33 to cover at least part of the corners.
[0047] Embodiment 2: The guard plate 33 is integrally formed and is provided with a plurality of wind gathering blades 4 .
[0048] In addition, the processing form between the wind gathering piece 4 and the guard plate 33: the wind gathering piece 4 can be formed as one piece with the guard plate 33, which reduces the difficulty of installation and avoids the wind gathering piece 4 from being unstable due to long-term use.
[0049] Alternatively, the air collecting fins 4 can also be formed separately from the guard plate 33 to reduce the difficulty of processing, and the appropriate installation position and number of the air collecting fins 4 can be rotated according to the actual size of the radiator 1.
[0050] In one embodiment, the guard plate 33 protrudes from the first mounting portion 31 to the second mounting portion 32, and the radiator 1, the guard plate 33 and the engine fan 2 are surrounded to form an assembly gap between the engine fan 2 and the radiator 1. An annular airflow is formed in the assembly gap, flowing circumferentially along the first mounting portion 31, and the gas at the assembly gap converges into the annular airflow at the assembly gap along the wind gathering plate 4.
[0051] Specifically: cold air enters the radiator 1, and the hot air after passing through the radiator 1 forms an annular airflow in the assembly gap under the rotation of the engine fan 2 blades. Since the wind shield 3 is designed with a wind collecting piece 4, the wind collecting piece 4, the surface of the radiator 1 and the guard plate 33 form a semi-closed cavity at the four corners of the radiator 1. The high-temperature gas flowing out of the four corners of the radiator 1 is driven by the negative air pressure generated by the action of the annular airflow and the guidance of the air guide channel. The airflow smoothly merges from the cavity into the annular airflow, and finally the hot air is discharged into the atmosphere through the engine fan 2.
[0052] It should be noted that since the air collecting piece 4 is arc-shaped, the air flow at the corner cavity flows out from the corner along the arc-shaped outer wall. At this time, the air guide channel can be regarded as formed by the arc-shaped outer wall, the radiator 1 and the guard plate 33.
[0053] Due to the combined effect of the wind collecting sheet 4 and the guard plate 33, the hot air at the four corners of the radiator 1 can be smoothly discharged from the radiator 1, thereby improving the overall heat dissipation efficiency of the radiator 1. In addition, this structure will not form air turbulence in the wind shield 3, thereby effectively improving the heat dissipation efficiency of the radiator 1 and reducing noise and vibration.
[0054] In one embodiment, the first mounting portion 31 is provided with a fastener connecting the wind shield 3 and the radiator 1, the engine fan 2 is provided with a mounting bracket connected to the second mounting portion 32, one of the mounting bracket and the second mounting portion 32 is provided with a limiting groove, and the other is provided with a limiting protrusion adapted to the limiting groove.
[0055] The fasteners may be bolts or other commonly used fasteners in the prior art, and preferably, a limiting protrusion is provided on the mounting bracket and a limiting groove is provided on the second mounting portion 32 to achieve connection between the engine fan 2 and the second mounting portion 32 .
[0056] In addition, the connection method between the radiator 1, the wind shield 3 and the engine fan 2 can adopt other connection and fixing methods in the existing technology, and there is no specific limitation on this.
[0057] The present application also includes an engine cooling device comprising a radiator 1 and an engine fan 2, with a wind shield 3 as described in the above embodiment disposed between the radiator 1 and the engine fan 2. The wind shield 3 acts on the engine cooling system to guide gas flow in the assembly gap, thereby improving the cooling efficiency of the conventional radiator 1 and reducing wind noise and vibration caused by turbulence in the radiator 1.
[0058] Anything not described in this application can be achieved by adopting or drawing on existing technologies.
[0059] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on the differences from other embodiments.
[0060] The foregoing is merely an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should all be included within the scope of the claims of the present application.
