Abstract
The utility model discloses a cooling device of internal combustion engine comprising a cylinder block, a cooling water tank outside the cylinder block, and a flywheel housing with flywheel below the cylinder block. The utility model is characterized in that, said flywheel is provided with a fan, and the flywheel housing is provided with an air guide cover which directs the air flow caused by fan rotation to the water tank. The utility model of cooling device of internal combustion engine has advantages of simple structure, good cooling effect and low cost.
Description
Technical field
The utility model relates to a kind of cooling unit of internal-combustion engine.
Background technique
In the prior art, the water-cooled cooling unit of mobile internal-combustion generally all has cooling water tank.And for the cooling of water tank, a kind of is with the fan that self driving mechanism directly drives water tank to be carried out distinguished and admirable cooling by internal-combustion engine; Another is to utilize motor ventilating fan that water tank is cooled off.The former need be provided with fan and corresponding driving mechanism, and the latter then needs to set up additional power supply and motor ventilating fan, and both are more complicated structurally, have all increased the manufacture cost of internal-combustion engine, and uses and safeguard all inconvenient.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of good cooling results and internal-combustion engine cooling unit simple in structure.
The purpose of this utility model is achieved in that a kind of cooling unit of internal-combustion engine, comprise cylinder block and be arranged on the outer cooling water tank of cylinder block, the cylinder block bottom is provided with flywheel casing, be provided with flywheel in the flywheel casing, it is characterized in that: described flywheel is provided with flabellum, and flywheel casing is provided with the wind scooper that the air-flow that the flabellum rotation is produced is guided water tank into.
The utility model replaces traditional separate fan by existing internal-combustion engine cooling unit is improved with the flabellum that is contained on the internal combustion engine flywheel.Internal-combustion engine drives the flabellum rotation in the running, and the air communication that flabellum produces is crossed the wind scooper that is located on the flywheel casing, directly delivers to water tank, takes away the heat that water tank produces because of heat exchange.Because the driving of flywheel flabellum is directed to the running of internal-combustion engine, need not to be provided with in addition separate fan again, also need not extra driving mechanism or fan electromotor and power supply.Therefore, this cooling unit is simple in structure, with low cost, easy to use and reliable.
Description of drawings
Fig. 1 is the structural representation of the utility model internal-combustion engine cooling unit.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
According to shown in Figure 1, internal-combustion engine cooling unit of the present utility model comprises cylinder body 1 and the cooling water tank 2 that is arranged on outside the cylinder body 1.Cylinder body 1 bottom is provided with flywheel casing 3, is provided with a flywheel that can pivot 4 in the flywheel casing 3.Flywheel 4 is provided with flabellum 5, and flabellum 5 can rotate under the drive of flywheel 4, and flabellum 5 is communicated with cooling water tank 2 by a wind scooper 6, and wind scooper 6 is fixed on the flywheel casing 3.During work, internal combustion engine operation, flywheel 4 are being with flabellum 5 rotations when rotating, and flabellum 5 arrives cooling water tank 2 places because of the air-flow that rotation produces along wind scooper 6.With air-flow cooling water tank 2 is taken away because of the heat that heat exchange produces, reached cooling purpose.The utility model is by the guiding of wind scooper 6, and the air-flow that the flabellum 5 that is contained on the flywheel 4 is produced because of rotation affacts on the cooling water tank 2, and water temperature is reduced.This internal-combustion engine cooling unit is simple in structure, with low cost, easy to use and reliable.
