Description
Technical field
The present invention relates to the hose assembly technical field, particularly a kind of automotive hose assembly with external thermostat.
Background technique
The heat that engine-cooling system is taken away account for fuel total release heat 20%～30%, motor is under the low temperature environment sub load, the heat that cooling system is taken away can be more.On the one hand, if the heat that engine-cooling system is taken away is too much, can make motor cold excessively, thereby produce combustion instability, it is slow to burn, and power descends, and fuel consumption raises.Lubricating oil viscosity is increased, cause insufficient lubrication, serious consequences such as parts depreciation aggravation.On the other hand, if in the motor cooling liquid to take away heat very few, can cause engine overheat; Thereby make petrol engine produce pre-ignition, pinking ablation piston head; Diesel injector gum deposit, overheated burning to death, cylinder cap thermal stress-cracking, a series of problems such as gas inlet outlet valve base distortion and gas leakage ablation valve.Therefore, the temperature of precision controlling cooling liquid, reasonable distribution cooling liquid are taken away heat and are become particularly important.
Thermostat can be regulated the water yield that gets into radiator automatically according to the height of cooling water temperature, changes the range of DO of water, and to regulate the heat dissipation potential of cooling system, the assurance motor is worked in suitable temperature range.The engine cooling degree is mainly carried out big short circle by thermostat control cooling liquid at present; Thereby the heat that the control cooling liquid is taken away; Using maximum thermostats in the positive drive type constituent is waxtype thermostat, and the working mechanism of waxtype thermostat is that the paraffin that is mixed with copper powder or aluminium powder is housed in the space between rubber pipe and the inductor, during normal temperature; It is solid-state that paraffin is, and valve is pressed on the valve seat.At this moment valve closing leads to the water route of radiator, from the cooling liquid of engine body water outlet, flows back to again in the body water jacket, carries out short circle.When the engine water temperature rise, paraffin is liquefy gradually, and volume increases thereupon, promotes valve opening, flows to radiator from the cooling liquid of body water outlet, and carries out major cycle.
Early stage thermostat is installed in the water intake or the water outlet of body, and the metal shell structure is because sealing and valve body complex manufacturing technology; The invention of the thermostat of nylon shell, its light weight, preparation process is simple; And use flexible pipe to be connected, avoided a sealing difficult problem with motor and annex.But the space is narrow and small in the engine compartment; The pipeline that is connected with thermostat, motor intake-outlet, radiator, annex is above 5; Tie point is more than 10; Thermostat is fixing on body, causes online being installed on man-hour, bulk assurance, the assembling operability of main engine factory all to have very big difficulty.Design a kind of assembly; The thermostat that wherein comprises plastic casing; And thermostat is connected on the interface that size circulates in engine body and radiator; Can not only solve the installation question of thermostat, can also simplify complicated engine-cooling system pipeline, the bulk that the time of the online installation of shortening main engine factory, reduction installation difficulty, assurance are installed.
Summary of the invention
The present invention proposes the automotive hose assembly with external thermostat, and concrete technological scheme is following:
The automotive hose assembly is by sebific duct motor water outlet sebific duct 1, short circle sebific duct 3, water inflow of the engine sebific duct 5, radiator water inlet sebific duct 6, radiator water outlet sebific duct 7, and thermostat 2, threeway 4 and jointing clip are formed; Motor water outlet sebific duct 1 connects motor water outlet connecting end joint and thermostat 2 connecting end joints; Short circle sebific duct 3 connects thermostat 2 connecting end joints and threeway 4; Water inflow of the engine pipe 5 connects threeway 4 and engine water inlet; Radiator inleting pipe 6 connects thermostat 2 connecting end joints and water inlet of radiator connecting end joint, and radiator water outlet sebific duct 7 connects radiator outlet and threeway 4.
All sebific ducts be connected the joint, termination, the interior warp of sebific duct is than the little 1～2mm of connecting end joint external diameter.
Thermostat of the present invention is commercially available external thermostat;
Threeway material of the present invention is PA66+GF30;
The clip that use pipeline assembly of the present invention joint divides two kinds of situation:
1, the port that is connected with radiator with motor uses turbine and worm clip or spring clip connected, also strip slip-collar not, and clip is assembled by main engine factory.
2, use the electrodeless clip of monaural, turbine and worm clip or spring clip with the port that thermostat is connected with threeway;
Clip of the present invention is the position that is connected with sebific duct of fastening thermostat, threeway, radiator, motor water inlet and outlet joint.
Pipeline assembly of the present invention can be realized when engine start or low-temperature working; Coolant temperature is lower; Thermostat cuts out major cycle; Cooling liquid flow through engine water outlet 1, thermostat 2, short circle sebific duct 3, threeway 4, water inflow of the engine pipe 5 are through the short circle motor that refluxes rapidly, the rapid warming-up of motor;
Pipeline assembly of the present invention can be realized when motor cruising or hot operation; Coolant temperature reaches the paraffin melt temperature; The thermostat main valve is opened; The high temperature coolant engine water outlet 1, thermostat 2, radiator inleting pipe 6 of flowing through gets into radiators, and the cryogenic liquid behind radiator heat-dissipation is through radiator outlet pipe 7, threeway 4, water inflow of the engine pipe 5 backflow motors, and cryogenic liquid is once more to engine cooling.According to the difference of coolant temperature, thermostat main valve lift is different, thereby control flows is regulated the coolant temperature of motor through the coolant rate of radiator major cycle.
The present invention passes through combined engine cooling system pipeline and annex, the bulk that the time of the online installation of shortening main engine factory, reduction installation difficulty, assurance are installed.
