Description

Cooling fan

A cooling fan, especially a cooling fan that can help the locomotive engine to dissipate heat and remove the dirt or other dirt between the cooling fan and the electric disk.

A generator is a device that converts kinetic energy and other forms of energy into electrical energy, and there are many types of generators. For example, the generator disk on the locomotive is a generator. In addition to generating electricity to recharge the battery, the generator disk can also Responsible for the power to the headlights, night lights, automatic choke, and the generator panel will generate high temperature after operation. Excessively high temperature will make the hysteresis phenomenon generated by the generator panel itself more serious, which will affect the power generation efficiency. Therefore, A cooling fan is installed on the generator disk of a general locomotive to draw in external air to radiate the generator disk and the engine. However, in order not to increase the load on the generator disk when rotating, the size and blade structure of the general cooling fan All of them are mainly lightweight, which results in the limited air volume and pressure generated by the cooling fan, so the cooling effect of the engine is greatly reduced. Or rain on rainy days, and dust and rain will be accumulated between the cooling fan and the power generation plate, which will indirectly affect The rotation efficiency of the cooling fan needs to be improved.

In view of the above problems, this creator based on years of experience in the design of cooling fan related industries, research and analysis of the structure of the cooling fan; for this reason, the main purpose of this creation is to provide a way to increase the air pressure and air volume to Improve the heat dissipation efficiency of the engine, and the heat dissipation fan to clean the dust or water accumulation between the fan and the power generation plate.

In order to achieve the above purpose, the cooling fan of the present invention is mainly formed by forming a number of first fan blades on one side of a blade body, and forming a number of second fan blades on the other side, wherein each first blade is formed separately There is a guide part and a pressurizing part. After the cooling fan sucks in the outside air, the sucked air can be further guided to the pressurizing part by the guide part, and then pressurize the air through the pressurizing part and send it to the engine for heat dissipation. Reduce the working temperature of the engine, and after the outside air is sucked in by the cooling fan, it can be further blown into the other side of the cooling plate body through the perforation, and the water accumulated between the cooling fan and the electric plate is cleared through the guide of several second fan blades Or dirt such as dust.
