Problems solved by technology

[0003] When the diesel engine is working, the diesel engine will generate a lot of heat. If the diesel engine is overheated, the diesel engine will be overloaded and run at low speed for a long time, which will cause the diesel engine to overheat and cause the water temperature to be too high, which is very harmful to the diesel engine, such as damaging the cylinder head gasket and burning the bearing bush. , a mechanical failure occurs, and the temperature is too high, which will also cause a decrease in the amount of air inflated, a decrease in power, boiling of the water tank, boiling and evaporation of cold water, smaller gaps between parts of the engine, and increased wear until the diesel engine stops
[0004] In order to overcome the problem of diesel engine overheating, cooling system and air-cooling system are used in the prior art, and the cooling system is equipped with a relatively complicated liquid circuit structure and high cost, while the structure of the air-cooling system is relatively simple, and the fan wheel is fixed on the crankshaft of the diesel engine In the above, when the crankshaft is working, the fan wheel is driven to blow the diesel engine. However, due to the limitation of the diesel engine body, the structure of the fan wheel is limited in the air cooling system, and the cooling gas generated by the fan wheel is limited, resulting in limited cooling effect of the diesel engine.
In order to overcome the problem of poor cooling of the air-cooled system, it is necessary to improve the air-cooled system

Embodiment 1

[0041] Basic as attached figure 1 , attached figure 2 And attached image 3 As shown, a forced air-cooled diesel engine body includes a mounting base 1, a housing 2 is integrally formed on the mounting base 1, a crankshaft hole 7 is opened on one side of the housing 2, and a ball bearing is installed in the crankshaft hole 7 (in the figure Not shown), the other side of the box body 2 has an installation port, the installation port is used to install the main structure of the diesel engine, the diesel engine in this embodiment is: 168FA diesel engine.

[0042] The cooling head 5 is integrally formed on the box body 2, and the cooling head 5 is fixed to the cylinder head 6 by fastening bolts. Several first cooling fins 51 are integrally formed on the cooling head 5, and a first air deflector is integrally formed on the first cooling fin. 61, the first heat dissipation groove 52 is formed between two adjacent first heat dissipation fins 51, the first heat dissipation hole 53 i...

Embodiment 2

[0048] The difference between embodiment two and embodiment one is that, as attached figure 1 As shown, there are several lightening grooves 4 on the top surface of the box body 2. In this embodiment, the longitudinal section of the lightening grooves 4 is rectangular, and the box body 2 is integrally formed with a support shaft 3, combined with the attached figure 2 The left end of the support shaft 3 is low and the right end is high, so that the support shaft 3 is inclined, and the support shaft 3 has an assembly hole (not shown).

[0049] The weight of the box body 2 can be reduced as a whole by the lightening groove 4, because the top surface of the box body 2 will be thinned due to the lightening groove 4, so that the thickness of the top wall of the box body 2 is reduced, so that the box body 2 Heat dissipation.

[0050] When installing the casing of the diesel engine body, the casing is installed on the support shaft 3, and the support shaft 3 makes the casing and the...

Abstract

The invention relates to the technical field of diesel engines, and discloses a forced air cooling diesel engine body. The forced air cooling diesel engine body comprises a box body and a cylinder head, a mounting opening is formed in one side of the box body, a crankshaft hole is formed in the other side of the box body, a mounting hole used for installing an oil sprayer is formed in one side ofthe cylinder head, and a heat dissipation head fixed to the box body is arranged between the box body and the cylinder head; heat dissipation holes are formed in the heat dissipation head and the cylinder head; and an air inlet located in one side of the mounting opening is formed in the cylinder head, an air channel communicating with the air inlet is formed in the cylinder body, and a cooling opening communicating with the air channel is formed in one side of the mounting hole. The forced air cooling diesel engine body is simple in structure, the diesel engine body can be rapidly cooled, andthe defects of an existing diesel engine air cooling system are overcome.

Description

technical field [0001] The invention relates to the technical field of diesel engines, in particular to a forced air-cooled diesel engine body. Background technique [0002] A diesel engine is an engine that burns diesel for energy release. The advantages of diesel engines are large torque and good economic performance. [0003] When the diesel engine is working, the diesel engine will generate a lot of heat. If the diesel engine is overheated, the diesel engine will be overloaded and run at low speed for a long time, which will cause the diesel engine to overheat and cause the water temperature to be too high, which is very harmful to the diesel engine, such as damaging the cylinder head gasket and burning the bearing bush. , Mechanical failure occurs, and the temperature is too high, which will also cause a decrease in the amount of air inflated, a decrease in power, boiling of the water tank, boiling and evaporation of cold water, smaller gaps between parts of the engine...
