Description

Technical Field

[0001] This utility model relates to the field of heat dissipation device technology, and specifically to a heat dissipation structure. Background Technology

[0002] Loaders are earthmoving machinery widely used in construction projects such as highways, ports, and mines. When loaders operate under extreme conditions, the engine generates a lot of heat, and the engine radiator cannot dissipate the heat in time, which can easily lead to high temperatures in the engine and transmission oil. In order to solve the problem of poor heat dissipation of the engine radiator, the engine cover is designed at present. The wind deflector with wind baffle can be referred to in the application publication number CN106870330A. The four corners of the wind deflector are beveled to improve the utilization rate of the workpiece, thereby reducing the turbulence phenomenon in the flow field and improving airflow.

[0003] The above solution reduces flow field turbulence and can improve heat dissipation. However, the loader's engine generates a lot of heat, and the hot air exhausted from the radiator returns to the air-cooled fan intake, causing a hot air recirculation phenomenon where the air temperature at the air-cooled radiator inlet increases. This hot air recirculation still affects the heat dissipation effect. Utility Model Content

[0004] To achieve the above objectives, one or more embodiments of this utility model provide the following technical solutions.

[0005] This utility model proposes a heat dissipation structure, including a chassis, an air guide shroud, and rubber baffles. The air guide shroud is fixedly installed on one side of the chassis, and the four corners of the air guide shroud are provided with bevels. A wind tunnel is installed through the air guide shroud, and a fan is rotatably installed inside the wind tunnel. Rubber baffles are inclinedly installed on both sides of the air guide shroud, and the rubber baffles have notches.

[0006] Further configured, the notch is a rectangular hole that penetrates the edge of the rubber windshield.

[0007] Further configured, the rubber wind deflector has an L-shaped cross-section, and the rubber wind deflector is fixedly mounted on the chassis by an L-shaped plate.

[0008] A further modification involves providing a beveled edge at the top of the rubber wind deflector.

[0009] Further configured, the chassis is a directional thin plate, and the chassis has several mounting holes.

[0010] A further provision is made that a reinforcing plate is fixedly installed at the connection between the air guide cover and the chassis.

[0011] A further configuration includes a bottom baffle on one side of the chassis, located between the rubber wind deflectors, with a cut surface between the two inclined surfaces near the baffle.

[0012] A further configuration is that the air duct passes through the air guide cover, and the air duct has a circular perforation.

[0013] Further configuration involves the fan being mounted inside a circular perforation, with the fan connected to a power supply cable.

[0014] Further configuration: the air guide cover and the chassis are integrated.

[0015] The beneficial effects of one or more of the above technical solutions:

[0016] The overlapping rubber wind deflector is fixed to the hood by an L-shaped plate, ensuring a tight fit between the wind deflector and the loader hood. When hot air recirculation occurs, the hot air blows towards the rubber wind deflector, which is then pressed tightly against the loader hood by the wind force. This physical barrier effectively limits the hot air recirculation and improves the cooling effect. A cross-section is set between the two inclined surfaces near the deflector to further improve space utilization and reduce airflow turbulence. Attached Figure Description

Detailed Implementation

[0021] The specific implementation of this embodiment will now be described with reference to the accompanying drawings.

[0022] A heat dissipation structure, as shown in the figure Figure 1 The system includes a chassis 1, an air guide shroud 2, and rubber wind deflectors 3. The air guide shroud 2 is fixedly installed on one side of the chassis 1. Sloping surfaces 4 are provided at the four corners of the air guide shroud 2. An air duct 5 is installed through the air guide shroud 2, and a fan 6 is rotatably installed inside the air duct 5. Rubber wind deflectors 3 are installed at an angle on both sides of the air guide shroud 2. Notches 8 are provided in the rubber wind deflectors 3; the notches 8 are rectangular holes that penetrate the edges of the rubber wind deflectors 3. (Refer to...) Figure 2 The notch 8 is attached to the rib 12 of the hood 13. When hot air backflow occurs, the hot air blows towards the rubber wind deflector. Under the action of the wind, the rubber wind deflector is pressed tightly against the loader hood, effectively limiting the hot air backflow through physical barrier.

[0023] The rubber wind deflector 3 has an L-shaped cross section and is fixedly mounted on the chassis 1 by an L-shaped plate 9. The L-shaped plate 9 has mounting holes 7. The chassis 1 is a thin plate with several mounting holes 7. The rubber wind deflector 3 can be mounted on the chassis 1 by bolts through the mounting holes 7.

[0024] The top of the rubber wind deflector 3 is provided with a bevel. The bevel can improve the disulfide trapping of airflow. A cross-section is provided between the two bevels 4 near the deflector to further improve space utilization and reduce flow field turbulence.

[0025] A reinforcing plate 10 is fixedly installed at the connection between the air guide shroud 2 and the chassis 1. An L-shaped reinforcing plate 10 is installed at the right-angle connection between the air guide shroud 2 and the chassis 1. The L-shaped reinforcing plate 10 is connected to the side wall of the air guide shroud 2 and the chassis 1 by welding, so that the L-shaped reinforcing plate 10 is connected to the air guide shroud 2 and the chassis 1 as a whole, further improving the connection strength between the air guide shroud 2 and the chassis 1.

[0026] A bottom baffle 11 is provided on one side of the chassis 1 and between the rubber wind deflectors 3. A cut surface is provided between the two inclined surfaces 4 near the baffle. The side of the chassis 1 between the two inclined surfaces 4 is cut off by the cut surface, which further improves the space utilization and reduces the flow field turbulence.

[0027] The air duct 5 passes through the air guide cover 2. The air duct 5 is a circular perforation. The inner diameter of the air duct 5 is larger than the vertical drop of the circular perforation. The fan 6 is rotatably installed in the circular perforation. The fan 6 is connected to the power supply line. The fan 6 is connected to the motor through the existing shaft. The motor drives the shaft to rotate. The power supply line is connected to the power source on the outside. The power source supplies power to the fan motor through the power supply line.

[0028] The air guide cover 2 and the chassis 1 are integrated into one piece. Specifically, they are made by integral molding and bending. There are no welds at the connection, so they will not break under long-term vibration, which extends the service life and reduces the production cost.

[0029] The principle for preventing hot air backflow is as follows:

[0030] Reference Figure 2 When hot air recirculation occurs, the direction of hot air recirculation is direction A. The hot air blows towards the rubber baffle 3. Under the action of the wind, the rubber baffle 3 is pressed tightly against the loader hood 13, which effectively restricts the hot air recirculation through physical isolation and improves the cooling effect.

[0031] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
