Description

Technical Field

[0001] The utility model relates to the technical field of drivers, and more specifically to a multifunctional driver with a high temperature protection function. Background Art

[0002] Multifunctional drives play a vital role in modern technological environments, not only because they can reduce the number of individual drivers required to operate equipment, but also because they increase the flexibility and efficiency of the system. Such drives are able to control and regulate different mechanical and electrical devices, such as servo motors, frequency converters, etc., ensuring that these devices can work together efficiently, thereby optimizing overall system performance.

[0003] When existing multifunctional drivers control multiple electrical appliances at the same time, they mainly rely on the natural flow of air and the heat absorption and heat dissipation effects of the structure to achieve the discharge of heat generated by internal components. They lack active heat dissipation structures. By setting up external exhaust equipment to discharge hot air from the driver, dust can easily enter the device through the air inlet on the driver, blocking the air inlet and causing high dust content inside, further exacerbating the problem of internal heat dissipation difficulties, posing certain safety hazards. In view of this, we propose a multifunctional driver with high temperature protection function. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet actual needs, and provide a multifunctional driver with a high-temperature protection function to solve the current technical problems that when the multifunctional driver controls multiple groups of electrical appliances, the internal components easily dissipate heat slowly, lack an active heat dissipation structure, and have certain safety hazards.

[0007] The utility model can increase the heat dissipation range by opening a through groove on the top of the driver body. At the same time, the heat dissipation fan arranged on the fixed ring can blow air into the driver body to improve the fluidity of the internal airflow. The design of the guide piece can disperse the blown wind to the surroundings, so as to speed up the delivery of internal heat to the heat dissipation port position of the driver body, thereby achieving the effect of accelerating the heat dissipation. In this way, excessive accumulation of internal heat can be reduced, the probability of high temperature of components can be reduced, and the high-temperature protection effect in the driver body can be effectively increased. The design of the dust cover can reduce the entry of external dust, thereby reducing the influence of dust on the heat dissipation of components.

[0008] Preferably, a hollow tube is fixedly provided at the bottom of the heat dissipation fan, two air inlet nozzles are fixedly provided on the outer tube wall of the hollow tube, and the air inlet nozzles are connected to the hollow tube.

[0009] Preferably, a ventilation cavity is provided downwardly through the top of the truncated cone-shaped diverter plate, and the ventilation cavity is detachably connected to the hollow tube.

[0010] Preferably, the dust cover comprises a shielding cover, the bottom of the shielding cover is symmetrically provided with two arc-shaped air inlet grooves, and dustproof nets are fixedly provided in the two air inlet grooves, and the inner edge of the bottom of the shielding cover is in contact with the outer wall of the fixing ring.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model can increase the heat dissipation range by opening a through groove on the top of the driver body. At the same time, the heat dissipation fan arranged on the fixed ring can blow air into the driver body to improve the fluidity of the internal airflow. The design of the guide piece can disperse the blown wind to the surroundings, so as to speed up the delivery of internal heat to the heat dissipation port of the driver body, thereby achieving the effect of accelerating heat dissipation. In this way, excessive internal heat accumulation can be reduced, the probability of high temperature of components can be reduced, and the high-temperature protection effect in the driver body can be effectively increased. The design of the dust cover can reduce the entry of external dust, thereby reducing the influence of dust on the heat dissipation of components.

[0015] 2. The utility model can also compress the wind blown downward by the diverter plate structure arranged obliquely on the guide member, so that the inclined surface of the diverter plate away from the inclined side can provide spiral flow guidance for the air when it flows through, so that after the air flows into the driver body in a dispersed manner, it has a certain flow angle, avoiding the problem of cooling dead corners caused by straight-line flow, and further improving the effect of discharging internal heat.

[0024] In an embodiment of the utility model, a ventilation cavity 304 is provided downwardly through the top of the truncated cone-shaped diverter disk 301, and the ventilation cavity 304 is detachably connected to the hollow tube 202; through the combination of the two, the wind in the hollow tube 202 can be blown to the bottom of the inner cavity of the driver body 1 through the connection with the ventilation cavity 304, thereby increasing the blowing and heat dissipation effect on the bottom.
