Description

Technical Field

[0001] The invention belongs to the technical field of intelligent drivers, and in particular relates to an intelligent driver. Background Art

[0002] Intelligent servo drive, also known as "programmable servo drive", is a fully digital drive that integrates servo drive technology, PLC technology, and motion control technology. It can be programmed with ladder diagrams to complete PLC logic and data operations, and realize multi-axis motor synchronization control functions through unique motion control instructions. Intelligent servo drive is part of the servo system and is mainly used in high-end equipment and core control components of intelligent machines. Intelligent servo drive can be widely used in textile machinery, woodworking machinery and other fields. Existing intelligent drives will generate a lot of heat during operation, and the existing heat dissipation method generally has a heat dissipation port or a heat dissipation fan outside the shell, but the heat dissipation effect is poor, and this method makes it easy for intelligent drives to accumulate dust, and most intelligent drives are relatively sophisticated, and dust will affect the life of the intelligent drive. Summary of the invention

[0003] The invention provides an intelligent driver, which has the characteristics of good heat dissipation effect and dust prevention.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an intelligent driver, comprising a driver, an inner shell is arranged on the outside of the driver, a second heat dissipation pipe is arranged on the bottom of the inner shell, the second heat dissipation pipe is arranged around the outside of the bottom of the driver, the second heat dissipation pipe is connected end to end to form a circulation pipe, the upper ends of both sides of the second heat dissipation pipe are connected to the first heat dissipation pipe, the first heat dissipation pipe is arranged on the outside adjacent to the upper end, a plurality of support rods are fixedly connected to the bottom of the inner shell, the lower ends of the support rods are connected to the bottom of the outer shell, the inner shell and the outer shell form a cavity, the heat dissipation fins penetrate the inner shell and are arranged in the cavity, and a fan is fixedly arranged on the outer wall of the outer shell at a position corresponding to the heat dissipation fins.

[0005] Preferably, a liquid inlet pipe is provided at the upper end of the first heat dissipation pipe, and a sealing cover is provided at one end of the liquid inlet pipe extending through the outer shell.

[0006] Preferably, a protective cover is provided on the outer side of the fan.

[0007] Preferably, a shock-absorbing pad is provided at the bottom of the housing.

[0008] Preferably, a plurality of heat dissipation holes are provided on the surface of the shell at positions corresponding to the cavity.

[0009] Preferably, the lower surface of the heat dissipation fin is arranged as an inclined surface in the direction toward the first heat dissipation tube.

[0010] Preferably, the first heat dissipation pipe is closely attached to the outer side of the driver.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The first heat dissipation tube and the second heat dissipation tube of the present invention absorb heat, and the second heat dissipation tube is filled with a working fluid. The liquid state of the working fluid evaporates into a vapor state when heated, and the fan blows air to make the vapor state of the working fluid move upward to the heat dissipation fins, and then transform into liquid when cooled, and then flow into the second heat dissipation tube along the lower surface of the heat dissipation fins, and then absorb heat and transform into vapor state, and repeat the cycle again, forming a liquid-vapor cycle to take away heat, thereby ensuring that the driver can dissipate heat efficiently, quickly and effectively.

[0013] 2. The driver of the present invention does not circulate with the outside air during the heat dissipation process, so that dust cannot enter the driver, thereby ensuring that the driver is not affected by dust and extending its service life. BRIEF DESCRIPTION OF THE DRAWINGS
