Description

Technical Field

[0001] This utility model relates to a high heat dissipation online soft starter. Background Technology

[0002] Online soft starters are devices used for starting and controlling electric motors, and are widely used in machinery, power systems, and other fields. Traditional online soft starters typically employ a side-mounted single-fan cooling and heat dissipation structure. While this design can meet basic cooling requirements, its heat dissipation capacity is relatively limited and cannot effectively cope with the demands of high-power operation or high-temperature environments. Especially under prolonged continuous operation, the accumulation of heat inside the device can lead to overheating, thereby affecting the stability and lifespan of the equipment. Improvements and optimizations are needed to address these issues. Utility Model Content

[0003] To address the above problems, the technical problem to be solved by this utility model is to provide a high-heat-dissipation online soft starter.

[0004] The technical solution adopted by this utility model of a high-heat-dissipation online soft starter is characterized by comprising a soft starter base, a soft starter bottom plate, a soft starter upper shell disposed above the soft starter base, an air-gathering plate, a cooling fan, and a fan cover disposed sequentially on both sides of the soft starter base. The soft starter base has an internal cavity, and the soft starter base has internal grooves on the upper and lower sides of the internal cavity. The internal grooves have air inlets communicating with the internal cavity, and the internal grooves also have positioning posts. The air-gathering plate includes an air-gathering plate body, and the air-gathering plate body has conical air-gathering holes spaced apart, communicating with the air inlets. The air-gathering plate body also has air-gathering plate docking holes corresponding to the positioning posts. The soft starter bottom plate is detachably installed below the soft starter base, and the bottom plate bottom plate has exhaust holes spaced apart in the middle, communicating with the internal cavity. The bottom of the soft starter bottom plate has a bottom plate lifting block.

[0005] It also includes a filter screen plate, and the front of the soft starter base plate is provided with a base plate positioning groove for installing and positioning the filter screen plate, and the base plate positioning groove is provided with a base plate exhaust hole.

[0006] The soft starter base plate is provided with base plate locking blocks on the left and right sides, and the bottom of the inner wall of the base cavity is provided with a base locking slot that engages with the base plate locking blocks.

[0007] The air-collecting plate body has an air-collecting plate partition block on the side near the cooling fan.

[0008] The fan cover includes a cover body, a cover plate docking seat inside the cover body, a cover plate docking hole inside the cover plate docking seat for inserting the top of the base positioning column, a cover plate elastic locking block on the cover body, and an inner recessed groove slot on the inner wall of the base groove that is opposite to the cover plate elastic locking block.

[0009] The advantages of this high-heat-dissipation online soft starter are as follows: the dual-fan convection structure and the exhaust vents on the bottom plate of the soft starter significantly improve the airflow inside the soft starter, enabling the equipment to cool down continuously and quickly, avoiding overheating and effectively extending the service life of the equipment; the air concentrator plate makes the cold air blown in by the fan more concentrated, effectively improving the cooling efficiency and ensuring a more significant heat dissipation effect, while reducing the leakage of cold air and the overflow of hot air from the air inlet, avoiding problems that affect the heat dissipation effect.

Detailed Implementation

[0012] like Figure 1-7As shown, the high-heat-dissipation online soft starter of this utility model includes a soft starter base 1, a soft starter bottom plate 2, a soft starter upper shell 3 disposed above the soft starter base 1, an air-gathering plate 6, a cooling fan 4, and a fan cover plate 5 sequentially disposed on both sides of the soft starter base 1. The soft starter base 1 has a base internal cavity 10, and the soft starter base 1 has a base internal groove 11 on the upper and lower sides of the base internal cavity 10. The base internal groove 11 has a base air inlet 12 communicating with the base internal cavity 10, and a base positioning post 13 is also provided on the base internal groove 11. The air-gathering plate 6 includes an air-gathering plate body 15, and the air-gathering plate body 15 has conical air-gathering holes 16 spaced apart and communicating with the base air inlet 12.
