[0002] During the use of the snowplow, the motor and controller will generate a large amount of heat. If the heat is not discharged in time, the machine will overheat and burn, shortening the service life of the machine.

[0030] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0031] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0032] like Figures 1 to 6 As shown, a heat dissipation device includes a main body 100, a shielding structure 200, a first shielding surface 210, a first air inlet 300, a first air outlet 310, a second shielding surface 220, a first limiting portion 230, a second limiting portion 240, a second air inlet 101, a third air inlet 102, a second air outlet 103, and a centrifugal fan blade 110.

[0033] like Figures 1 to 4 As shown, a heat dissipation device is installed between a controller 500 and a driving component 600 in a snowplow, and the heat dissipation device includes a main body 100, and the main body 100 has a first air duct and a second air duct for respectively dissipating heat of the controller 500 and the driving component 600, wherein the first air duct includes an air guide channel formed by the controller 500 and the shielding structure 200; on the one hand, the heat dissipated by the controller 500 is gathered in the air guide channel, thereby avoiding the heat interference of the controller 500 to other components; on the other hand, the heat dissipated by the controller 500 can be accelerated to flow into the main body 100, thereby effectively improving the heat dissipation efficiency of the controller 500.

[0034] Specifically, in this embodiment, the main body 100 is formed by an upper cover 120 and a lower cover 130, and forms a detachable connection with the inner wall of the snowplow accommodating chamber 410. The main body 100 is connected to the driving component 600 and the controller 500 from left to right in sequence, wherein the driving component 600 is placed inside the main body 100, and the main body 100 has a first air duct and a second air duct for heat dissipation of the controller 500 and the driving component 600 respectively. The first air duct is located on the right side of the main body 100, and includes an air guide channel formed by the controller 500 and the shielding structure 200. The air guide channel allows a relatively closed space to be provided between the controller 500 and the heat dissipation device, thereby avoiding heat dissipation of the controller 500 and effectively reducing the heat interference of the controller 500 to other components.

[0035] In this embodiment, the shielding structure 200 includes a first shielding surface 210 arranged on the side of the main body 100 close to the controller 500, and forms a covering shape on the surface of the controller 500, so that the air guide channel has only a first air inlet 300 connected to the outside. This not only effectively prevents the heat of the controller 500 from being dissipated from other surfaces, ensuring the protection of other components and improving the stability and service life of the snow blower, but also allows cold air to enter the controller 500 through the first air inlet 300 to achieve heat dissipation of the controller 500.

[0036] In this embodiment, the shape of the first shielding surface 210 is adapted to the shape of the ventilation surface of the controller 500, and is arc-shaped, irregular, or plate-shaped. Preferably, in this embodiment, the first shielding surface 210 is plate-shaped, extending in a direction away from the main body 100, and the extension length is adapted to the length of the controller 500.

[0037] To further ensure the heat dissipation efficiency of the controller 500, in this embodiment, the shielding structure 200 also includes a second shielding surface 220, which is plate-shaped and arranged perpendicular to the first shielding surface 210. One end of the second shielding surface 220 is connected to the first shielding surface 210, and the other end extends toward the direction close to the first air inlet 300, thereby forming a partial blockage on the first air inlet 300 to reduce the size of the first air inlet 300, thereby increasing the wind speed in the air guide channel, thereby effectively improving the heat dissipation efficiency of the controller 500.

[0038] In this embodiment, when the second shielding surface 220 abuts against the first air inlet 300, the controller 500 is clamped between the second air inlet 101 and the second shielding surface 220, which effectively prevents the controller 500 from moving laterally along the length direction of the radiator during the heat dissipation process and ensures the stability of the installation of the controller 500.

[0039] like Figure 4 As shown, in order to further improve the stability of the controller 500 during the heat dissipation process, in the present embodiment, the shielding structure 200 also includes a first limiting portion 230 and a second limiting portion 240, and the first limiting portion 230 and the second limiting portion 240 are respectively engaged with the surface of the controller 500 away from the first air inlet 300 to form a limit on the longitudinal and height directions of the controller 500, so that the controller 500 does not vibrate or shake with the airflow during the heat dissipation process, thereby effectively ensuring the stability of the controller 500 during the heat dissipation process.

[0040] In this embodiment, the first limiting portion 230 is arranged on the opposite side of the first shielding surface 210, extends along the width direction of the controller 500, and is engaged with the outer surface of the controller 500 to limit the height direction of the controller 500, thereby preventing the controller 500 from moving up and down in the height direction during the heat dissipation process.

[0041] Preferably, in this embodiment, the first limiting portion 230 is in the shape of a strip plate, and is arranged on the opposite side of the first shielding surface 210 and close to one end of the first air inlet 300, one end of which is connected to the inner wall of the snowplow accommodating chamber 410, and the other end is clamped to the outer surface of the controller 500.

[0042] In this embodiment, the second limiting portion 240 is arranged on the vertical side of the first shielding surface 210 away from the snowplow accommodating chamber 410, extends along the height direction of the controller 500, and is clamped with the outer surface of the controller 500 to form a limit on the longitudinal direction of the controller 500, thereby preventing the controller 500 from moving forward and backward in the width direction during the heat dissipation process.

[0043] Preferably, in this embodiment, the second limiting portion 240 is in the shape of a strip plate and is arranged in the middle of the width direction of the controller 500. One end of the second limiting portion 240 is detachably connected to the inner wall of the snowplow accommodating chamber 410 through a fastener to adjust the clamping tightness to facilitate the installation of the controller 500, and the other end is clamped to the outer surface of the controller 500.

[0044] In order to achieve heat dissipation of the controller 500, in this embodiment, the air guide channel includes a first air outlet 310 connected to the first air inlet 300, and the main body 100 includes a second air inlet 101 connected to the first air outlet 310, so that the heat in the controller 500 enters the second air inlet 101 through the first air outlet 310 and is discharged through the main body 100, thereby achieving heat dissipation of the controller 500.

[0045] In this embodiment, the driving component 600 is located inside the main body 100, and the main body 100 includes a third air inlet 102 connected to the outside. The third air inlet 102 corresponds to and is connected to the driving component 600, so that external cold air can enter the main body 100 through the third air inlet 102 to cool the driving component 600, thereby achieving heat dissipation of the driving component 600.

[0046] like Figure 5 to Figure 6 As shown, in order to achieve efficient heat dissipation of the controller 500 and the driving component 600, in the present embodiment, a centrifugal fan blade 110 connected to the output end of the driving component 600 is provided in the main body 100, and the main body 100 also includes a second air outlet 103 corresponding to and connected to the rotation direction of the centrifugal fan blade 110, so that when the centrifugal fan blade 110 rotates, the heat generated by the controller 500 and the driving component 600 can be respectively absorbed into the main body 100, and discharged through the second air outlet 103, thereby achieving efficient heat dissipation of the controller 500 and the driving component 600.

[0047] Among them, the centrifugal fan blade 110 includes a partition 111 located in the middle of the second air outlet 103 channel, and a first blade 112 and a second blade 113 arranged on the opposite surface of the partition 111. The first blade 112 corresponds to the controller 500 through the second air inlet 101, and the second blade 113 corresponds to the driving component 600. Since the first blade 112 and the second blade 113 are separated by the partition 111, there is no interference between the two when they rotate, so that the controller 500 and the driving component 600 can be cooled separately, avoiding interference between the controller 500 and the driving component 600 when cooling.

[0048] In this embodiment, the first blade 112 cooperates with the partition 111, the second air inlet 101, the air guide channel and the second air outlet 103 to form a first air duct, and the second blade 113 cooperates with the partition 111, the third air inlet 102 and the second air outlet 103 to form a second air duct. When the first air duct dissipates heat, the driving component 600 drives the first blade 112 to rotate, so that the external cold air enters the air guide channel through the first air inlet 300 to cool the controller 500, and at the same time contacts the controller 500. The formed hot air enters the second air inlet 101 through the first air outlet 310, and is discharged through the second air outlet 103 under the action of the first blade 112, thereby achieving heat dissipation of the controller 500; at the same time, the second blade 113 rotates synchronously, so that external cold air enters the main body 100 through the third air inlet 102 to cool the driving component 600, and at the same time, the hot air formed by contact with the driving component 600 is discharged through the second air outlet 103 under the action of the second blade 113, thereby achieving synchronous heat dissipation of the driving component 600.

[0050] A snowplow body 400, wherein the snowplow body 400 has a receiving chamber 410, and a controller 500 and a driving component 600 are installed in the receiving chamber 410 and are arranged adjacent to each other;

[0051] The heat dissipation device is arranged between the controller 500 and the driving component 600, and includes a main body 100, which has a first air duct and a second air duct for dissipating heat of the controller 500 and the driving component 600 respectively, wherein the first air duct includes an air guide channel formed by the controller 500 and the shielding structure 200.

[0052] In this embodiment, the controller 500 includes a ventilated first contact surface 510, a second contact surface 520 and a third contact surface 530, wherein the first contact surface 510 is in contact with the second air inlet 101 of the main body 100 and is connected to the interior of the main body 100 so that the heat of the controller 500 can be absorbed into the main body 100, the second contact surface 520 is arranged perpendicular to the first contact surface 510, and is fittedly connected to the first shielding surface 210 to prevent the heat of the controller 500 from being conducted from the bottom to other components, the third contact surface 530 is arranged perpendicular to the second contact surface 520, and is opposite to the first contact surface 510, and the third contact surface 530 is fully or partially connected to the outside, so that the air guide channel has only one first air inlet 300 connected to the outside, which effectively ensures the heat concentration and heat dissipation efficiency of the controller 500.

[0053] To ensure the stability of the placement of the controller 500, in this embodiment, a plurality of convex ribs 420 protruding toward the direction close to the controller 500 are provided on the inner wall of the accommodating cavity 410 corresponding to the installation position of the controller 500. The convex ribs 420 can fill the height of the curved surface of the accommodating cavity 410 so that the controller 500 can be placed horizontally.
