Description

Technical Field

[0002] A diesel generator set consists of an engine, a generator and a control system. A diesel generator set is a power supply device that uses a diesel engine as the prime mover to drive a synchronous generator to generate electricity. It is a power generation device that has quick start-up, convenient operation and maintenance, low investment, and strong environmental adaptability. It has a very wide range of application prospects and is divided into common units, standby units and emergency units according to their uses. In daily use, a large amount of high-temperature hot air is difficult to diffuse inside the diesel generator, making the temperature of the diesel generator set itself high for a long time, which can easily cause short circuit and burning of components in the diesel generator assembly. Therefore, it is necessary to dissipate heat from the diesel generator set.

[0003] A fast heat dissipation device for a diesel generator set is introduced in CN202122792362.7. After the motor is working, the drive rod and the drive column are driven to rotate, so that the movable rod can swing left and right, and then the fan connected to the movable rod can swing left and right, which can increase the area of ​​the fan's wind sweeping on the surface of the diesel generator set body, thereby speeding up the heat dissipation speed of the diesel generator set body. By setting the heat dissipation fins and the connecting holes, the disc-shaped heat dissipation fins can increase the contact area with the cold water in the fixed box, so as to efficiently dissipate heat. The connecting holes can interconnect the inside and outside of the heat dissipation fins, so that the cold water can effectively flow into the heat dissipation fins, fully dissipate heat, and solve the problem of poor heat dissipation effect. The present application provides a new heat dissipation structure to dissipate heat on the surface of the diesel generator set, accelerate the heat conduction efficiency inside and outside the diesel generator set, and facilitate the heat dissipation of the diesel generator set.
