AI Technical Summary
Traditional sheet-like heat dissipation tooth structures limit the flexibility of controller placement in new energy vehicles, resulting in poor component selection compatibility and increased development costs.
The traditional sheet-like heat dissipation fins have been replaced with columnar heat dissipation fins to ensure that the ventilation between the heat dissipation fins is not affected by the layout direction of the controller and the wiring direction. The columnar heat dissipation structure is integrally molded with the heat dissipation base to ensure good air circulation.
It improves the adaptability and compatibility of the controller in the overall vehicle layout, saves materials, reduces weight, and maintains the same heat conduction and heat dissipation effect.

TECHNICAL FIELD
[0001] The utility model relates to electric automobile controller heat dissipation structure design technical field, concretely relates to a kind of heat dissipation tooth shape and arrangement structure. BACKGROUND
[0002] With the rapid development of new energy vehicle industry in our country, the space inside whole vehicle is more and more compact, and the arrangement of each component is more and more demanding to meet the demand of space arrangement and space shortage of whole vehicle.
[0003] The controller arranged by traditional sheet-shaped heat dissipation tooth structure must keep the ventilation direction between heat dissipation teeth consistent with the running direction of vehicle, but the ventilation direction between heat dissipation teeth of controller cannot keep consistent with the running direction of vehicle due to the influence of three-phase line and positive and negative line of controller.
[0004] Traditional sheet-shaped heat dissipation tooth limits the product selection in the arrangement stage of new energy vehicle, and the compatibility of component selection of vehicle enterprises on the market is poor, so if there is conflict in arrangement, vehicle enterprises must adjust the space of whole vehicle to adapt to components or vehicle enterprises must reselect, which will increase development cost. UTILITY MODEL CONTENT
[0005] The utility model aims at providing a heat dissipation tooth structure not affected by the arrangement direction of controller, changing traditional sheet-shaped heat dissipation tooth into columnar shape, so that the air flow around heat dissipation column is not affected whether the controller is arranged horizontally or vertically due to other arrangement requirements, sufficient air flow is ensured to realize heat dissipation of controller, and the compatibility and adaptability of controller in vehicle arrangement are higher.
[0006] In order to achieve the above purpose, the technical scheme of the utility model is as follows: a heat dissipation structure of electric automobile controller includes controller upper shell and controller heat dissipation base, traditional sheet-shaped heat dissipation tooth is changed into columnar shape, and the controller with the heat dissipation structure can be arranged flexibly on whole vehicle, the arrangement of controller is changed after the influence of wiring sequence and wiring direction of U-phase line interface (2), V-phase line interface (3) and W-phase line interface (4) and the outlet direction of controller positive terminal (5) and controller negative terminal (6), columnar heat dissipation tooth (1) can still ensure ventilation between teeth, so that the ventilation and heat dissipation of heat dissipation tooth are not affected.
[0007] Similarly, the ventilation condition between heat dissipation tooth (1) of the structure can not be affected by the direction of environmental wind during vehicle driving.
[0008] The utility model discloses a beneficial effect is: compared with traditional radiating tooth structure, this structure does not control the arrangement direction influence, need not strictly require and vehicle operation direction is identical, makes the compatibility of the adaptation of controller on whole vehicle arrangement higher, and this radiating structure adopts die casting form and radiating base integral moulding simultaneously, is more material saving under the same heat conduction radiating effect, and material utilization is higher, and the weight is lighter.

[0016] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0017] like Figure 1 Figure 2 As shown, this embodiment proposes a heat dissipation structure for a motor controller, including an upper housing (8), a heat dissipation base (7), and columnar heat dissipation teeth (1). The columnar heat dissipation teeth (1) are located below the base (7). The upper housing (8) and the heat dissipation base (7) are fixed with bolts. The U-phase wire connection port (2), V-phase wire connection port (3), W-phase wire connection port (4), controller positive wire connection port (5), and controller negative wire connection port (6) are arranged side by side on the upper part of the upper housing (7).
[0018] Furthermore, the columnar heat dissipation teeth (1) are located below the controller heat dissipation base (7) and are integrally cast with the controller heat dissipation base (7). The controller heat dissipation base (7) and the columnar heat dissipation teeth (1) have better heat conduction effect. With the same amount of material, this structure has a larger heat dissipation area.
[0019] Furthermore, the cylindrical heat dissipation tooth (1) has an overall cylindrical shape. The controller with this heat dissipation structure can be flexibly arranged on the vehicle. After the overall arrangement of the controller is changed due to the influence of the three-phase line and the positive and negative line output direction, the windward area of the cylindrical heat dissipation tooth (1) itself is not affected.
[0020] Furthermore, such as Figure 2 As shown, the columnar heat dissipation teeth (1) are evenly distributed horizontally, vertically, and diagonally below the controller heat dissipation base (7), so that the controller can ensure good ventilation between the teeth regardless of the arrangement, thus ensuring that the heat dissipation effect is not affected.
[0021] Compared with traditional heat dissipation tooth structure, columnar heat dissipation tooth (1) has a larger heat dissipation area under the same material weight compared with traditional plate heat dissipation tooth. This structure saves more material under the same heat conduction and heat dissipation effect, with higher material utilization and lighter weight.
[0022] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
