[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] Example: See Figure 1 , the utility model provides a technical solution: a motor driver with efficient heat dissipation.
[0025] Among them, a heat-conducting base plate 2 is embedded and installed on the left and right sides of the base 1, a heat-conducting connecting rod 3 is provided on the top of the heat-conducting base plate 2, a heat-conducting seat 4 is fixedly connected between the two heat-conducting connecting rods 3, a heat-conducting seat 4 is provided on the top of the heat-conducting seat 4, a fan frame 6 is provided on the front of the heat-conducting fin 5, and a cooling fan 7 is installed inside the fan frame 6.
[0026] The heat dissipation fan 7 is arranged on the top of the heat dissipation fan 6, and the heat dissipation fan 7 is arranged on the top of the heat dissipation fan 6. ...
[0027] A protective cover 12 is provided above the base 1 , and a heat dissipation hole 13 is provided on the back side of the protective cover 12 near the top.
[0028] In this embodiment, a protective cover 12 is installed on the top of the base 1 to wrap the entire heat dissipation device. The heat in the protective cover 12 is blown away from the heat dissipation holes 13 by the heat dissipation fan 7, so that the internal temperature will not continue to rise. In this way, the operator will not touch the heat-conducting material when picking up the device, and will not be burned by accidentally touching the working heat-conducting material.
[0029] Among them, a slideway 8 is provided horizontally through the center of the base 1, and U-shaped rods 9 are provided at both ends of the slideway 8. A fixing screw 10 is provided at one end of the U-shaped rod 9, and an installation screw 11 is provided at the other end of the U-shaped rod 9. The fixing screw 10 is rotatably installed inside the slideway 8.
[0030] In this embodiment, the U-shaped rod 9 is pulled out from the slide 8, the fixing screw 10 passes through the top of the base 1, and the fixing screw 10 is continuously rotated until it presses the U-shaped rod 9 to fix the U-shaped rod 9. The mounting screw 11 at the other end is screwed into the mounting hole of the driver to install the device on the corresponding driver. The heat-conducting base plate 2 fits the driver to absorb the heat generated by the driver. The length of the U-shaped rod 9 is adjusted so that the device can be installed on drivers of different sizes.
[0031] The bottom area of the heat-conducting bottom plate 2 is larger than the top area.
[0032] In this embodiment, the heat-conducting bottom plate 2 is in a trapezoidal plane with a smaller top and a larger bottom, which maximizes the contact area between the bottom and the driver and provides a better heat absorption effect.
[0033] Among them, the heat-conducting base plate 2, the heat-conducting connecting rod 3 and the heat-conducting seat 4 are all made of metal materials with good heat transfer effect, the heat sink 5 is made of aluminum alloy or copper alloy, and the protective cover 12 is made of non-metallic material with good heat insulation effect.
[0034] In this embodiment, metal materials have better thermal conductivity. The aluminum heat sink 5 is lightweight and has a lower cost. Copper has a better heat dissipation effect but is more expensive. Generally, the material of the thermal conductive base plate 2, the thermal conductive connecting rod 3 and the thermal conductive seat 4 is the same as that of the heat sink 5. This makes the joints smoother and the heat transfer effect better. The protective cover 12 needs to be insulated and its own temperature cannot be too high. Therefore, it needs to be made of non-metallic materials with good thermal insulation effect to prevent operators from being burned when touching it.
[0035] The slideway 8 has embedded areas at both ends of the base 1 .
[0036] In this embodiment, the middle of the slide 8 is connected, the U-shaped rod can extend into the interior of the slide 8, and the mounting screws 11 are left in the embedded area on the side of the base 1, so that there are no additional protrusions on the side of the base 1. This makes it more convenient to transport and install the device and avoids bumps.
[0037] Working principle: Pull the U-shaped rod 9 out of the slide 8, continue to rotate the fixing screw 10 until the U-shaped rod 9 is pressed to fix the U-shaped rod 9, and screw the mounting screw 11 at the other end into the mounting hole of the driver to install the device on the corresponding driver. Install the device on the top of the driver, and the heat-conducting base plates 2 on both sides of the bottom of the base 1 fit the surface of the driver. At the same time, install the protective cover 12. The heat generated by the driver is transferred to the heat-conducting base plate 2, and flows from the heat-conducting base plate 2 to the heat-conducting connecting rod 3 and into the heat-conducting seat 4, and finally reaches the heat sink 5. The airflow generated by the cooling fan 7 takes away the heat, and finally install the protective cover 12.
