Description

Technical Field

[0001] The utility model relates to the technical field of air-water cooling treatment, and more specifically, to an air-water cooling device in a frequency converter device. Background Art

[0002] The inverter will have a certain amount of heat loss during operation. Since the inverter is installed indoors, if the heat cannot be discharged in time, the indoor ambient temperature will gradually rise. If the inverter works in a high temperature environment for a long time, its life will be shortened. Therefore, an air-water cooling device is needed to cool the inverter. When the existing air-water cooling device cools the inverter, it is not convenient to adjust the air outlet angle, resulting in local high temperature inside the inverter and uneven cooling, which affects the service life of the inverter.

[0003] Patent application publication number: CN218335725U An air-water cooling device for a frequency conversion cabinet achieves the effect of adjusting the wind direction by setting an adjustment mechanism, so that the frequency conversion cabinet is cooled evenly, which can avoid local high temperature inside the frequency conversion cabinet, thereby not affecting the service life of the frequency conversion cabinet, and by setting a filtering mechanism, the coolant is filtered to avoid clogging of the water inlet pipe.

[0004] However, when this structure is actually used, the hot air generated by the inverter during operation is transported to the inner cavity of the air-to-water cooling device body through the air inlet pipe, and heat exchange is performed through the cold air output by the air-to-water cooler, thereby cooling the air, rather than directly acting on the heating elements of the inverter. As a result, it is difficult to introduce the cold air into the heating elements quickly and in multiple directions, thereby affecting the heat dissipation and cooling effects of the inverter.
