Description

Technical Field

[0001] The utility model belongs to the technical field of exciters, and in particular relates to an air duct structure of a rotating silicon rectifier exciter. Background Art

[0002] The rotating silicon rectifier exciter itself is a motor, which will generate heat during actual operation. The designs of the exciters for various units are varied. When the exciter generates heat during operation, the internal fan will be started for ventilation and heat dissipation. During this period, the air inlet and outlet pipes at the bottom of the exciter will intake and exhaust air accordingly. However, the air inlet and outlet pipes are usually designed as open ducts, and the air inlet and outlet are designed in the outlet room, resulting in a higher temperature in the outlet room. At the same time, the open design of the exciter air duct has the risk of inhaling foreign matter, so it is considered to be modified. For this purpose, a rotating silicon rectifier exciter air duct structure is designed. Utility Model Content

[0003] The utility model aims to provide an air duct structure of a rotating silicon rectifier exciter to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rotating silicon rectifier exciter air duct structure, comprising a fixed platform, on which an exciter assembly and a generator assembly are respectively fixedly arranged, an air inlet pipe and an air outlet pipe are respectively connected on the lower surface of the exciter assembly, and the adjacent ends of the air inlet pipe and the air outlet pipe are commonly connected with a cooling frame, the upper surface of the cooling frame is fixedly connected to the lower surface of the fixed platform, an inner cooling pipe is arranged inside the cooling frame, a plurality of fixed rods are fixedly connected to the lower surface of the fixed platform, and the bottom ends of the plurality of fixed rods are commonly fixedly connected with a cooling machine frame, an outer cooling pipe is arranged on the cooling machine frame, and the two ends of the outer cooling pipe are respectively connected with the two ends of the inner cooling pipe, an air cooler assembly is arranged below the fixed platform, a fan is arranged on the air cooler assembly, two circulation pipes are connected on the air cooler assembly, one end of the two circulation pipes is connected and arranged on the generator assembly, and a circulation pump is arranged on the outer cooling pipe.

[0005] By connecting the air inlet pipe and the air outlet pipe to the cooling frame, when the fan in the exciter assembly blows the hot air into the cooling frame through the air outlet pipe, the hot air will be cooled by the internal cooling pipe in the cooling frame, and then the cooled gas will be circulated into the exciter assembly through the air inlet pipe to achieve the effect of circulating heat dissipation of the exciter assembly. During this period, since the air inlet pipe and the air outlet pipe are connected as a whole through the cooling frame, the heat dissipation air duct in the exciter assembly is sealed. Compared with the traditional open air duct, there is no risk of foreign matter being sucked into the air inlet, which helps to ensure the operating safety of the machine body. In addition, by cooling the hot gas sent from the air outlet pipe into the cooling frame, it helps to ensure the stability of the temperature between the outlet lines.

[0006] As a preferred implementation manner, the exciter assembly is coaxially connected to the generator assembly.

[0007] As a preferred implementation, the adjacent ends of the air inlet pipe and the air outlet pipe are connected via a cooling frame.

[0008] As a preferred implementation, the cooling frame is located above the air cooler assembly.

[0009] By setting the cooling machine frame above the air cooler assembly, when the fan is started, the start of the fan will not only drive the heat exchange operation of the air cooler assembly, but also simultaneously blow to the external cooling pipe on the cooling machine frame, so that the coolant in the external cooling pipe can dissipate heat and cool down, and then the external cooling pipe can exchange hot and cold liquid with the internal cooling pipe under the pump power of the circulating pump, thereby achieving the cooling effect of the hot air in the cooling frame.

[0010] As a preferred implementation manner, a first supporting leg is fixedly connected to the lower surface of the fixing platform.

[0011] As a preferred implementation, a second supporting leg is fixedly connected to the lower surface of the air cooler assembly.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model connects the air inlet pipe and the air outlet pipe on the cooling frame. When the fan in the exciter assembly blows the hot air into the cooling frame through the air outlet pipe, the hot air will be cooled by the internal cooling pipe in the cooling frame. Thereafter, the cooled gas is circulated into the exciter assembly through the air inlet pipe to achieve the effect of circulating heat dissipation of the exciter assembly. During this period, since the air inlet pipe and the air outlet pipe are connected as a whole through the cooling frame, the heat dissipation air duct in the exciter assembly is sealed. Compared with the traditional open air duct, there is no risk of foreign matter being sucked into the air inlet, which helps to ensure the operating safety of the machine body. In addition, by cooling the hot gas sent from the air outlet pipe into the cooling frame, it helps to ensure the stability of the temperature between the outlet lines.

[0014] The utility model arranges the cooling machine frame above the air cooler assembly. When the fan is started, the start of the fan will not only drive the heat exchange operation of the air cooler assembly 11, but also simultaneously blow to the external cooling pipe on the cooling machine frame, so that the coolant in the external cooling pipe can dissipate heat and cool down. Then, the external cooling pipe can exchange hot and cold liquid with the internal cooling pipe under the pump power of the circulating pump, thereby achieving the cooling effect of the hot air in the cooling frame.
