[0035] Specifically, as shown in Figure 1As shown, the first axis and the second axis, which pass through the center of the mounting hole 11 and are perpendicular to each other, divide the plate 1 into a first region, a second region, a third region and a fourth region. Each of the first region, the second region, the third region and the fourth region is provided with a vent 14. The vent 14 in each region can allow the cooling airflow to be blown from each position of the plate 1 to the lubrication oil circuit of the gearbox, thereby ensuring a uniform cooling effect on the lubrication oil circuit.
[0036] Specifically, the plate 1 is made of stainless steel, and the mounting hole 11 is circular. The two ends of the plate 1 are welded or bolted to the gearbox housing. The motor is fixed in the mounting hole 11, the motor body is located above the plate 1, and the fan blades of the cooler are located below the plate 1.

[0039] Furthermore, such as Figure 2As shown, the cooler support further comprises a first convex rib 2 and a second convex rib 3, which are distributed on the other two opposite edges of the plate body 1, and can enhance the rigidity and strength of the plate body 1, prevent the edge position of the plate body 1 from being distorted due to uneven force, and further improve the stability of the cooler support; specifically, the plate body 1 is rectangular, the mounting hole 11 is arranged at the center position of the plate body 1, the first slot hole 12 and the second slot hole 13 are symmetrically arranged on the opposite two edges of the plate body 1 about the first axis, the first convex rib 2 and the second convex rib 3 are the same shape, and the first convex rib 2 and the second convex rib 3 are symmetrically arranged on the other two opposite edges of the plate body 1 about the second axis, and the length of the first convex rib 2 and the length of the second convex rib 3 are the same as the length of the edge of the plate body 1.
[0040] The corners of the first convex rib 2 and the second convex rib 3 are rounded to prevent the corners from being too sharp to scratch the construction personnel, thereby improving the safety of the cooler support; at the same time, it can also reduce the stress concentration at the corners to avoid wear and tear and cracks.

The first slot hole 12 and the second slot hole 13 are symmetrically formed on the edge of the plate body 1 about the first axis, and the first slot hole 12 and the second slot hole 13 are symmetric about the second axis, so that the cooler support has an axis of symmetry, and the symmetry axes are the first axis and the second axis, which is simple in structure, easy to manufacture, and greatly improves the stability of the cooler support during the operation of the cooler, and reduces the risk of resonance.
[0046] In order to ensure the structural rigidity of the plate body 1 and improve the carrying capacity of the plate body 1, in this embodiment, the wind hole 14 is not communicated with the first slot hole 12 and the second slot hole 13, and the wind hole 14 is not communicated with the mounting hole 11, that is, the four wind holes 14 and the mounting hole 11 are independent and closed holes.
