Description
Technical field
The present invention relates to a kind of water cooling system, particularly a kind of constituent that is used for the internal-combustion engine cooling.
Background technique
The function of the cooling system of internal-combustion engine is that heat energy a part of in the combustion process is in time conducted, and the influence that makes the internal-combustion engine various piece not changed by use condition and external condition is in best working state always.But there are following two problems in general internal-combustion engine cooling system: the water that the existing internal-combustion engine cooling system of one side will cool off is directly discharged, and does not recycle, and has wasted great amount of water resources; Whole cooling procedure is not carried out temperature control on the other hand, when engine temperature is too high, can not cool off timely like this and have influence on the service behaviour of internal-combustion engine; Can make again that when temperature is low friction between piston and the cylinder increases, thereby influence the service behaviour of internal-combustion engine.
Summary of the invention
The technical issues that need to address of the present invention provide a kind of internal-combustion engine cooling system that can implement temperature control to the internal-combustion engine cooling procedure.
For solving the problems of the technologies described above, internal-combustion engine temperature control cooling system of the present invention comprises cooling waterpump and water inlet and outlet return, and said internal-combustion engine temperature control cooling system also comprises the temperature control water tank, Flow valve, waste pipe and temperature transducer; Said cooling waterpump, water inlet and outlet return and waste pipe all are connected on the temperature control water tank; Said Flow valve is arranged on the connecting tube of cooling waterpump and temperature control water tank; In the said temperature control water tank first temperature transducer is set, in the water inlet return second temperature transducer is set; Said drainage pipe is provided with control valve.
Fixing a lot of radiating fin on the said temperature control water tank.
After adopting said structure, second temperature transducer that is provided with on the water inlet return can be monitored the temperature regime of internal-combustion engine, in time understands the height of engine temperature; First temperature transducer that is provided with in the temperature control water tank can be monitored the temperature of the cooling water that internal-combustion engine is cooled off.Data through temperature transducer are regulated Flow valve, and the input quantity of control cold water reaches temperature controlled purpose.The water inlet return is connected on the temperature control water tank, makes cooling water to recycle, and has practiced thrift water resources.Be fixed with a lot of radiating fin on the temperature control water tank, can better dispel the heat, reduced the input quantity of cold water, improved radiating efficiency the water in the temperature control water tank.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed explanation.
Fig. 1 is the structural representation of internal-combustion engine temperature control cooling system of the present invention.
Among the figure: 1 is the temperature control water tank, and 2 is cooling waterpump, and 3 is cylinder, and 4 are the water outlet return, and 5 are the water inlet return, and 6 is waste pipe, and 7 is control valve, 8 Flow valves, 9 first temperature transducers, 10 second temperature transducers
Embodiment
Internal-combustion engine temperature control cooling system as shown in Figure 1 comprises cooling waterpump 2 and water inlet and outlet return, and cooling waterpump 2 employing compact structures, the centrifugal water pump that carrying capacity is big can replenish cold water rapidly like this and cool off when engine temperature is higher.The water inlet and outlet return comprises water outlet return 4 and water inlet return 5, and both are integrated, are attached on cylinder 3 walls of internal-combustion engine.Cooling water is a water outlet return 4 through the part before the casing outer wall, is water inlet return 5 through the part after the casing outer wall.Turnover described here for temperature control water tank 1, cooling waterpump 2, the water inlet and outlet return all is connected on the temperature control water tank 1.Be provided with Flow valve 8 between cooling waterpump 2 and the temperature control water tank 1, come the cold water water output of 2 pairs of temperature control water tanks 1 of cooling waterpump through regulating Flow valve 8, and then reach the purpose of regulating the water temperature in the temperature control water tank 1.
Said internal-combustion engine temperature control cooling system also comprises waste pipe 6 and temperature transducer.Waste pipe 6 also is connected on the temperature control water tank, and waste pipe 6 is provided with control valve; Main like this is when reaching the highest for the water level in temperature control water tank 1, and discharge section water can cool off so that the water in the cooling waterpump 2 joins in the temperature control water tank 1 fast timely.First temperature transducer 9 is set in the said temperature control water tank 1, in the water inlet return 5 second temperature transducer 10 is set; Can monitor the water temperature that gets into outlet conduit 4 and water inlet return 5 so simultaneously; Can recognize the cold and hot situation of cylinder 3 so indirectly; Control the temperature of cooling water in the temperature control water tank 1 through regulating Flow valve 8, make water temperature can not cross cold and cause the friction between piston and the cylinder 3 to increase.When the temperature of cylinder 3 is higher, can also be through opening large-capacity valve 8, cooling waterpump replenishes cold water countercylinder 3 rapidly and cools off.
