Technical Field

[0001] The utility model belongs to the technical field of heat dissipation of insulation monitors, and particularly relates to a heat dissipation structure for an internal power supply of an insulation monitor. Background Technique

[0002] An insulation monitor is a device for online real-time detection and management of the insulation status of the bus and branches of a DC power supply system. When the existing internal power supply of the insulation monitor is operating, the generated heat cannot be quickly discharged from the inside of the instrument, resulting in too high a surface temperature of the internal power supply and reducing its service life. For this reason, we propose a heat dissipation structure for the internal power supply of an insulation monitor. Content of the Utility Model

[0003] The purpose of the utility model is to provide a heat dissipation structure for the internal power supply of an insulation monitor. By designing an insulation monitor chassis, heat dissipation holes, an internal power supply, and a heat dissipation mechanism, when the internal power supply of the insulation monitor is operating, the generated heat can be quickly discharged from the inside of the insulation monitor chassis, so that the internal power supply will not have its service life shortened due to excessive temperature during operation, effectively improving the service cycle of the internal power supply. The overall structure is compact and has strong practicability.

[0004] To achieve the above object, the utility model provides the following technical solution: A heat dissipation structure for the internal power supply of an insulation monitor, including an insulation monitor chassis. Heat dissipation holes for dissipating heat are provided on both sides of the insulation monitor chassis. An internal power supply is installed inside the insulation monitor chassis. A heat dissipation mechanism is arranged outside the internal power supply. The heat dissipation mechanism includes an aluminum heat conduction base attached to the top surface of the internal power supply. A copper heat conduction pipe for heat conduction is arranged inside the aluminum heat conduction base. Aluminum heat conduction fins are fixedly sleeved on the surface of the copper heat conduction pipe. Vertical plates are arranged on both sides of the aluminum heat conduction fins. The bottom ends of the vertical plates are fixedly connected to the inner bottom surface of the insulation monitor chassis. Holes are provided on the side surfaces of the vertical plates, and heat dissipation fans are installed inside the holes.

[0005] Preferably, a dust prevention mechanism is further included. The dust prevention mechanism includes slide rails. The number of the slide rails is two in total. The two slide rails are respectively located at the top ends of both sides of the insulation monitor chassis. A connecting slide plate is slidably connected to the bottom ends of the slide rails. A dust prevention net is arranged at the bottom end of the connecting slide plate.

[0006] Preferably, heat conduction silicone grease is coated on the contact surface between the internal power supply and the aluminum heat conduction base.

[0007] Preferably, the heat dissipation fans are flush with the aluminum heat conduction fins, and the heat dissipation fans are electrically connected to an external power supply.

[0008] Preferably, the dust prevention net is detachably connected to the connecting slide plate.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0010] 1. By designing the insulation monitor chassis, heat dissipation holes, built-in power supply, and heat dissipation mechanism, when the built-in power supply of the insulation monitor is running, the generated heat can be quickly discharged from the inside of the insulation monitor chassis, so that the built-in power supply will not have its service life shortened due to excessive temperature during operation, effectively improving the service life of the built-in power supply.

Heat dissipation holes 2 for dissipating heat are provided on both sides of the insulation monitor chassis 1. A built-in power supply 3 is installed inside the insulation monitor chassis 1. A heat dissipation mechanism is arranged outside the built-in power supply 3 for quickly guiding the heat generated by the built-in power supply 3 out of the interior of the insulation monitor chassis 1. The heat dissipation mechanism includes an aluminum heat conduction base 4 attached to the top surface of the built-in power supply 3. A copper heat conduction pipe 5 for heat conduction is arranged inside the aluminum heat conduction base 4.

Heat dissipation fans 9 are installed inside the holes 8. A heat conduction silicone grease is applied to the contact surface between the built-in power supply 3 and the aluminum heat conduction base 4, so that when the built-in power supply 3 operates, the generated heat can be transferred to the aluminum heat conduction base 4 more quickly. The heat dissipation fans 9 are flush with the aluminum heat conduction fins 6, and the heat dissipation fans 9 are electrically connected to an external power supply, so that the heat dissipation fans 9 can take away the heat conducted by the aluminum heat conduction fins 6 more quickly, and the heat dissipation performance of the heat dissipation fans 9 is better; when the insulation monitor operates, the heat generated by the built-in power supply 3 will be quickly transferred to the copper heat conduction pipe 5 by the aluminum heat conduction base 4, and then absorbed and transferred by the copper heat conduction pipe 5, and finally quickly absorbed and transferred and dissipated by the aluminum heat conduction fins 6. Then, the heat dissipation fans 9 in operation quickly guide the heat transferred by the aluminum heat conduction fins 6 to the heat dissipation holes 2 and discharge it out of the interior of the insulation monitor chassis 1 through the heat dissipation holes 2, realizing the quick heat dissipation operation of the built-in power supply 3 of the insulation monitor; when the existing built-in power supply of the insulation monitor operates, the generated heat cannot be quickly discharged from the interior of the instrument, resulting in too high a surface temperature of the built-in power supply and reducing its service life; by designing the insulation monitor chassis 1, the heat dissipation holes 2, the built-in power supply 3, and the heat dissipation mechanism, the heat generated by the built-in power supply 3 of the insulation monitor can be quickly discharged from the interior of the insulation monitor chassis 1 when it operates, so that the built-in power supply 3 will not have its service life shortened due to too high a temperature during operation, effectively improving the service cycle of the built-in power supply 3. The overall structure is compact and the practicability is strong.

[0018] In this embodiment, preferably, a dust-proof mechanism is further included. The dust-proof mechanism includes a slide rail 10. The number of the slide rails 10 is set to two.
