[0002] When the motor controller runs, the internal power conversion module will heat, and the heat needs to be introduced to the casing through the contact surface to dissipate heat, so as to maintain the temperature of the power conversion module not to exceed a certain value, and guarantee the stable operation of the motor controller. Figure 1 As shown in the figure, the lower part of the casing is used for installing the controller, the upper part of the casing is arranged with a certain height and a wave-shaped heat dissipation rib, and the heat on the casing is dissipated through the heat dissipation rib and air convection. The heat dissipation rib increases the contact area of the casing and air, improves the convection heat dissipation of air, and the casing is provided with a fan below, which plays a role of sucking the cold air above downward, and the air enters the heat dissipation rib and improves the convection heat dissipation of air, so as to guide the heat of the module from the middle to the surrounding environment. The existing casing has the following disadvantages: the heat dissipation rib is arranged on the whole casing, and more materials are used, and due to the unreasonable arrangement of the heat dissipation rib, the heat conduction and dissipation capacity of the air in the heat dissipation rib is poor, and the heat dissipation effect is general.

[0005] The blank area is used for arranging cables, plastic shells and the like, and the heat generation is small, so the heat dissipation rib can be omitted to reduce the material consumption; the long heat dissipation ribs and the short heat dissipation ribs are distributed at intervals, which ensures the speed of the hot air in the middle part dissipating from the heat dissipation rib, improves the heat dissipation area, and thus improves the heat dissipation efficiency; the setting mode of the heat dissipation rib diverging from the center to the periphery makes the hot air in the middle part diverge to the periphery after being fully disturbed and absorbing heat, increases the export direction of the hot air, and improves the heat dissipation efficiency.

[0007] As preferred, the line connecting each guide heat dissipation rib to the end of the middle heat dissipation rib is parallel to the middle heat dissipation rib. The heat dissipation rib is more beautiful and the mold is convenient to manufacture.
[0008] As preferred, the blank area and the middle heat dissipation rib are further provided with several front heat dissipation ribs with "U" shape and opening forward, the middle part of the front heat dissipation rib is parallel to the middle heat dissipation rib, and the two ends of the front heat dissipation rib extend to the edge of the shell. The front heat dissipation rib improves the heat dissipation capacity of the edge of the blank area.
[0009] As preferred, the shell is provided with short heat dissipation ribs in the area between the two ends of the front heat dissipation rib and the middle heat dissipation rib, improving the heat dissipation capacity of the edge of the blank area.
[0010] As preferred, the short heat dissipation rib is parallel to the end part of the front heat dissipation rib, improving the outflow rate of air.
[0011] As preferred, all the heat dissipation ribs are integrally formed by die casting, and the draft angle is between 1-1.5°.
[0012] Compared with the prior art, the utility model has the advantages of:
[0013] The blank area is used for arranging cables and plastic shells and the like, and heat generation is small, so the heat dissipation rib can be omitted to reduce the material usage;

[0024] Embodiment one, as Figures 2-4 Shown, a kind of controller shell structure with heat dissipation rib, including shell 1 and the heat dissipation rib 2 of vertically arranged setting in the outer surface of shell 1, the middle part of shell 1 is provided with two ends extend to the middle heat dissipation rib 21 of the edge of shell 1, for easy to illustrate, when the heat dissipation rib of shell 1 is vertically placed, the direction of heat dissipation rib relative to shell 1 is upper, the horizontal extension direction of middle heat dissipation rib 21 is left-right direction, shell 1 is provided with the blank area 11 of not being provided with heat dissipation rib in the side of middle heat dissipation rib 21, and with this side as the front side of shell 1, shell 1 is provided with several long heat dissipation ribs 22 and the several short heat dissipation ribs 23 of length shorter than long heat dissipation rib 22 in the rear of middle heat dissipation rib 21, long heat dissipation rib 22 and short heat dissipation rib 23 are distributed with interval, one end of long heat dissipation rib 22 extends to the edge of shell 1, the other end is towards the middle part of middle heat dissipation rib 21 and does not connect with middle heat dissipation rib 21, one end of short heat dissipation rib 23 extends to the edge of shell 1, the other end is towards the middle part of middle heat dissipation rib 21.
[0025] Four long heat dissipation ribs 22 located close to the middle position are respectively connected with guide heat dissipation rib 24 towards the end of middle heat dissipation rib 21, guide heat dissipation rib 24 is perpendicular to middle heat dissipation rib 21 and does not connect with middle heat dissipation rib 21. Guide heat dissipation rib 24 is parallel to each other, avoids the condition that air cannot be dissipated to occur due to long heat dissipation rib 22 in the center place distance too close.
[0026] The connecting line of every guide heat dissipation rib 24 towards the end of middle heat dissipation rib 21 is parallel to middle heat dissipation rib 21. Make the heat dissipation rib more beautiful, at the same time, facilitate the production of mould.
[0027] Several U-shaped, forward-facing front heat dissipation ribs 26 are also provided between the blank area 11 and the central heat dissipation rib 21. The middle part of the front heat dissipation rib 26 is parallel to the central heat dissipation rib 21, and both ends of the front heat dissipation rib 26 extend to the edge of the shell 1. The front heat dissipation ribs 26 improve the heat dissipation capacity of the edge of the blank area 11.
[0028] The housing 1 has a front short heat dissipation rib 27 in the area between the two ends of the front heat dissipation rib 26 and the middle heat dissipation rib 21, which improves the heat dissipation capacity of the edge of the blank area 11.
[0029] The short front heat dissipation fin 27 is parallel to the end of the front heat dissipation fin 26, which increases the air outflow rate.
[0030] All cooling fins are integrally formed by die casting, with a draft angle between 1 and 1.5°.
[0031] Compared with the prior art, this embodiment has the following beneficial effects:
[0032] The blank area is used for laying cables and plastic shells, etc., which generate little heat, so the heat dissipation fins can be omitted to reduce the amount of material used; the long heat dissipation fins 22 and the short heat dissipation fins 23 are distributed alternately, which increases the heat dissipation area while ensuring the speed at which the hot air in the middle is dissipated from the heat dissipation fins, thereby improving the heat dissipation efficiency; the way the heat dissipation fins are arranged from the center to the surrounding areas allows the hot air in the middle to absorb heat after being fully disturbed before dissipating to the surrounding areas, which increases the direction of hot air output and improves the heat dissipation efficiency.
[0033] Verified through numerical simulation. Figure 5 and Figure 6 The existing solution and this embodiment are compared respectively. Compared with the original solution, the heat dissipation effect achieved by this design solution reduces the average temperature of the module by 1.38℃ and reduces the volume of materials used by 23.64%.
