Embodiment approach
[0056] On the one hand, in order to achieve the above purpose, a cooling device for a frequency conversion cabinet of the present invention includes;
[0057] Condenser assembly 4: used to reduce the temperature of high temperature liquid, see Figure 4 As shown, it is mainly composed of a casing 44, a water cooling pipe 42, a water pump 43 and a condenser. The condenser and the water pump 43 are connected through the water cooling pipe 42 to form a circulating water circuit. The water pump 43 provides power for the flow of circulating water. The liquid flowing through the condenser is cooled under the action of the condenser. In order to optimize the overall solution, part of the water-cooling pipe 42 passes through the casing 44, and the water-cooling pipe 42 passing through the casing 44 is distributed in a spiral shape. It is worth noting Yes, the water pump 43 and the condenser are both existing components, so I won’t make too many statements here. During the specific sel...
