Problems solved by technology

However, due to part manufacturing and assembly errors and the fact that the fan and the windshield are not on the same vibration source, the smaller the blade tip clearance is, the easier it is for the tip of the fan to come into contact with the windshield when the fan vibrates, which affects the use of the fan.

Embodiment Construction

[0027] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention is capable of various changes in different embodiments without departing from the scope of the present invention, and that the description and illustrations therein are illustrative in nature and not limiting. this invention.

[0028] The present invention provides a heavy-duty truck, which includes a frame and an engine fixed on the frame, and the engine includes an engine body, a radiator, a fan 200 and a windshield 100 . The radiator is fixed on the engine body, the windshield 100 is fixed on the radiator, and the fan 200 is rotatably connected to the windshield 100 . The heat generated when the engine is working is transferred to the radiator, and the rotation of the fan 200 drives the flow of air to realize heat exchange between the radiator and the outside. The windshield...

Abstract

The invention relates to a heavy truck, an engine and a fan guard. The fan guard is provided with a fan guard ring used for containing a fan, and a fixing hole is formed in the fan guard ring; the fan guard further comprises an annular brush, the annular brush comprises a base body and a plurality of flexible bristles fixed to the base body, and the base body can be fixed to the fixing hole through a fastener, so that the outer periphery of the base body is attached to the inner periphery of the fan guard ring, and the fixing hole is sealed; and each bristle extends in the radial direction of the air guard ring. Due to the arrangement of the annular brush, a gap which is small enough is formed between the fan guard and the blade tips of a fan, and therefore the heat dissipation efficiency of a heat dissipation device is improved. When the fan runs, the blade tips of the fan are prevented from being in contact with the fan guard ring, and mutual interference between the fan guard ring and fan blades is avoided. The gaps between the tail ends of the bristles and the tips of the fan blades of the fan are 3-8 mm, and the performance of the fan can be improved by about 8%.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a heavy-duty truck, its engine and a windshield. Background technique [0002] The main components of the cooling system in the car are the radiator and the fan, and the windshield is a transitional part between the radiator and the fan. The effect of airflow. [0003] With the improvement of engine power and emission control, the heat dissipation required by the engine is increasing, and the requirements for the cooling system of the vehicle are getting higher and higher. Maximizing the performance of the fan will help meet the heat dissipation requirements of the vehicle, and at the same time reduce Fan specifications to reduce power consumption. The function of the windshield is to ensure that all the air generated by the fan flows through the radiator to improve the efficiency of the fan; to make the air more evenly distributed on the heat dissipation core and to prevent th...
