Generator with simultaneous cooling of multiple components

Abstract

The invention provides a multi-component simultaneously cooled generator, which at least includes an engine, a motor assembly connected to the engine transmission, and a frame for installing the engine and the motor assembly, and is characterized in that it also includes a centrifugal fan and an inverter And the muffler, the centrifugal fan is arranged at one end of the motor assembly and the motor assembly is located between the fan and the engine to form a double air intake heat dissipation passage where the air flows from the engine to the centrifugal fan and from the outside of the centrifugal fan, The fan is connected to the engine drive, the muffler and inverter are arranged on the air outlet side of the centrifugal fan and the muffler is located at the air outlet of the heat dissipation channel; cooling, and has a simple structure and is easy to manufacture, reducing the manufacturing difficulty and cost of the generator.

Description

technical field [0001] The invention relates to a generator, in particular to a generator with simultaneous cooling of multiple components. Background technique [0002] Generators are extremely important power supply equipment in modern life, and are widely used in backup power supply, field operations and other fields. Existing generator comprises following structure: engine, motor assembly (motor assembly includes rotor and stator), cooling fan, inverter, muffler, frame and oil tank; Generator can produce a large amount of heat in the course of work, and these heat It mainly comes from the engine, motor components and inverter. The high-temperature exhaust gas generated by the engine will also cause the temperature of the muffler to rise. This heat will seriously affect the performance of the generator. For example, if the temperature is too high, the insulation of the motor components will decrease. , and even cause the generator to burn out; if the temperature is too h...

Existing generator comprises following structure: engine, motor assembly (motor assembly includes rotor and stator), cooling fan, inverter, muffler, frame and oil tank; Generator can produce a large amount of heat in the course of work, and these heat It mainly comes from the engine, motor components and inverter. The high-temperature exhaust gas generated by the engine will also cause the temperature of the muffler to rise. This heat will seriously affect the performance of the generator. For example, if the temperature is too high, the insulation of the motor components will decrease. , and even cause the generator to burn out; if the temperature is too high, the performance of the inverter will decrease; although the engine itself has a cooling system, its local temperature will also be too high, resulting in a decrease in the performance of the engine. If the temperature is too high, it will also affect the motor components. For the temperature problem of the generator, there are currently many designs. Although it can play a role in the heat dissipation of the generator, it cannot simultaneously control the inverter, the engine and the motor components. Cooling, if all the above-mentioned components are cooled, but the design structure of the cooling air duct is extremely complicated, which will increase the difficulty of manufacturing the generator itself, thereby increasing the manufacturing cost of the generator
