Abstract

The inventio provides an energy storage motor cooling system fan. The energy storage motor cooling system fan comprises a first fan, a second fan and a support. The first fan and the second fan are mounted on the support. The first fan comprises a first impeller and a first motor. The first impeller and an output shaft of the first motor are connected. The first impeller comprises a reinforced ring and wide blades evenly distributed along the circumference of the first impeller. The reinforced ring is connected with each wide blade. The first fan is used for providing high-flow cooling air. The second fan comprises a second impeller and a second motor. The second impeller is connected with an output shaft of the second motor, and the second motor is used for providing power for the secondimpeller. The second impeller comprises long blades and short blades units. The short blade units are evenly distributed in the circumferential direction of the second impeller. The long blades are evenly arranged between the short blade units at intervals. Each short blade unit comprises at least one short blade. The second fan is used for providing low-flow cooling air. The energy storage motorcooing system fan meets different cooling needs of the two motors of an energy storage motor, and compared with a conventional fan, the fan has the advantage that the fan efficiency is improved by 6%to 8%.

Description

technical field [0001] The invention relates to the technical field of motor cooling, in particular to a fan of an energy storage motor cooling system. Background technique [0002] With the rapid development of my country's equipment manufacturing technology in recent years, higher requirements have been put forward for the performance, appearance, reliability and safety of products; the fan of the energy storage motor cooling system, as the core component of the heat dissipation of the energy storage motor cooling system, has been Efficiency improvement, vibration reduction, noise reduction and weight reduction are gradually required. The energy storage motor consists of two motors. The first motor has higher heat dissipation requirements and needs to provide high-flow cooling air. The second motor has lower heat dissipation requirements, and the cooling requirements of the two fans are quite different. Cooling with high-flow fans will cause energy waste. If low-flow fans ...
