Problems solved by technology
At present, in order to make the overall layout of the multi-motor controller meet the requirements of miniaturization, light weight, and compactness, the heat sink is usually placed under the power module and the controller, which makes the heat sink only for the power module and the controller. Heat dissipation at the bottom, on the one hand, is not conducive to the internal heat dissipation of multi-motor control; on the other hand, since only one side of the radiator performs the heat dissipation function, it itself has not been fully utilized
Therefore, the heat dissipation efficiency of the heat sink in the existing multi-motor controller is very low

Embodiment approach
[0045] In the second embodiment of the multi-motor controller provided by the present invention, on the basis of the above-mentioned first embodiment, the heat dissipation main board of the multi-motor controller is changed from a plate shape to a square ring shape.
[0046] The cross-sectional shape of the heat sink main board is changed to a square ring shape. Not only the outer surface of the heat sink main board can realize the heat dissipation function, but also the inner wall can realize the heat dissipation function. Obviously, the surface area of the heat sink increases, which not only increases the heat dissipation area of the heat sink, At the same time, the supporting area of the heating device is increased, which is convenient for use in occasions with many heating devices and high heat.
[0047] Compared with the above-mentioned first embodiment, the heat dissipation of the main board is changed from two sides to eight sides, and the heat dissipation efficien...

The invention discloses a multi-motor controller which comprises a plurality of heat generating devices and a heat dissipating device (1) for dissipating the heat of the heat generating devices and acasing (2) which supports the heat dissipating device (1) and has a cavity, wherein the heat dissipating device (1) extends from a side of the casing (2) into a middle portion of the inner cavity suchthat the heat dissipating device (1) can dissipate heat of the heat generating devices mounted around. A positioning device (3) is further included to facilitate the fixation of the relative positionof the heat dissipating device (1) and the casing (2). Since the heat dissipating device (1) is located at the centers of the heat generating devices, each side of the heat dissipating device (1) canfully play a heat dissipating role, and the heat dissipating efficiency is significantly improved. The invention also discloses a control device, since the control device comprises the multi-motor controller with high heat dissipation efficiency described above, the control device is more stable, and the improvement of the reliability of a product is facilitated.
