Abstract
The utility model discloses an internal combustion engine cooling device which comprises an internal combustion engine body and a cooking water tank arranged outside the internal combustion engine body. The utility model is characterized in that the cooling water tank is communicated with the internal combustion engine body through a set of natural circulation waterway which is composed of an upper water pipe and a lower water pipe that are respectively communicated with the internal combustion engine body. The upper water pipe of the water tank is higher than the upper water outlet of the internal combustion engine body, and the lower water pipe of the water tank is higher than the lower water inlet of the internal combustion engine body. A motor fan is arranged on the cooling water tank. The internal combustion engine cooling device of the utility model has the advantages of simple structure, favorable cooling effect and low cost.
Description
Technical field
The utility model relates to a kind of internal-combustion engine cooling unit.
Background technique
The internal-combustion engine cooling unit of prior art generally is divided into two kinds.A kind of is pump circulation cooling, is provided with one group of circulation waterway between the low temperature area of the high-temperature zone of the cylinder sleeve of internal combustion engines, cylinder cap and outer tank.This circulation waterway utilizes the running of water pump, to the cooling water between high-temperature zone and the low temperature area circulate, heat exchange, reach the purpose of cooling cylinder sleeve, cylinder cap.Help flow of cooling water though the cooling unit of this structure has water pump to drive, cooling effect is better, because water pump needs extra motivational drive, so the internal structure more complicated and the cost of cooling unit are higher.Another is not circulating and evaporating cooling, directly is full of cooling water between internal combustion engine cylinder jacket, the cylinder cap, comes cooling internal combustion engines by evaporation of water.This cooling unit need not water pump and external impetus drives, and relatively simple for structure, cost is also lower, but its cooling effect is relatively poor.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, good cooling results, internal-combustion engine cooling unit with low cost are provided.
The purpose of this utility model is achieved in that a kind of internal-combustion engine cooling unit, comprises internal combustion engine main body and is located at the outer cooling water tank of internal combustion engine main body, and it is characterized in that: described cooling water tank is communicated with internal combustion engine main body by one group of natural circulation water route.
Described natural circulation water route is made up of water inlet that is communicated with internal combustion engine main body respectively and sewer.
Described water tank water inlet is higher than the upper water-out mouth of internal combustion engine main body, and the water tank sewer is higher than the following water intake of internal combustion engine main body.
Described cooling water tank is provided with motor ventilating fan.
The utility model is by improving existing internal-combustion engine cooling unit, and the water tank that is interconnected with water inlet and sewer replaces traditional water pump cyclic water tank.The water of water tank is heated when entering cylinder body by sewer, and density reduces.Hot water rises along inboard wall of cylinder block, discharges through water inlet, is back to water tank, and the low temperature water of water tank is in time replenished into cylinder body from the bottom.This structure does not need the circulating water pump of additionaling power, and the cooling water in the water tank promptly can automatic cycle flow, and internal-combustion engine is cooled off, thereby its cost is lower, and cooling effect is better.
Description of drawings
Fig. 1 is the structural representation of the utility model most preferred embodiment.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
According to shown in Figure 1, internal-combustion engine cooling unit of the present utility model comprises internal combustion engine main body 1 and is located at internal combustion engine main body 1 cooling water tank 2 outward.Be communicated with one group of natural circulation water route between cooling water tank 2 and the internal combustion engine main body 1, this natural circulation water route is made up of water inlet 3 and sewer 4, and water inlet 3 all is communicated with internal combustion engine main body 1 with sewer 4.The water outlet of water tank water inlet 3 is higher than the upper water-out mouth of internal combustion engine main body 1, and the water intake of water tank sewer 4 is higher than the following water intake of internal combustion engine main body 1, can normally move to guarantee cooling water recirculation system.During work, the water in the cooling water tank 2 is in sewer 4 enters internal combustion engine main body 1.When water temperature raise, its density reduced, and hot water rises, and discharged internal combustion engine main body 1 through water inlet 3, was back in the cooling water tank 2, so was concatenated to form natural circulation.Along with the variation of internal-combustion engine machine-heating load, the speed of circulation of cooling water also can be adjusted accordingly automatically, and the efficient of cooling can not descended.For the hot water of discharging from water inlet 3 can be cooled off fast, a motor ventilating fan 5 independently is set cooling water tank 2 outside, be used to quicken the cooling of cooling water tank 2 interior water.The utility model adopts natural cooling circuit water route structure, need not extra cooling waterpump, and is simple in structure, and good cooling results.
