The cooling water pipe of the engine has the advantages that the effect of sealing between the cooling water pipe and a cylinder cover can be improved, the heat dissipation effect of a whole heat dissipation system can be improved, the product weight is reduced, and the number of the installation steps is reduced.
Description
Technical field
The utility model belongs to engine-cooling system accessory field, especially relates to a kind of cooling water pipe of engine.
Background technique
In motor, need a cold water pipe, this water pipe is connected with engine cylinder cap, and engine coolant flows through water-cooling tube from cylinder head inside, then the radiator of flow direction engine, plays motor is carried out to cooling effect.At present, people know that the cooling water pipe of engine generally using with factory is to enter casting by aluminum alloy altogether, and its appearance quality is poor and weight is large, and inboard wall of tube body is coarse, and cooling liquid can produce larger resistance while flowing therein, affects radiating effect; Employing aluminium Foundry Production cost is high, the easily pollution of generation to environment in process of production, and installation steps are loaded down with trivial details, and sealing effect is subject to the impact of operation factors larger.Have that product appearance is of poor quality, weight is large, complex installation process, sealing effect are poor, inner wall roughness high-technology problem.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of cooling water pipe of engine, can improve sealing effect and radiating effect, reduces product weight simultaneously, easy for installation.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of cooling water pipe of engine, comprise slice and lower, described upper slice and lower structure that is injection molding, upper slice and lower become a cavity by Vibration welding, described cavity comprises a main channel and at least one tributary waterway being communicated with main channel, tributary waterway water intake is positioned at lower, tributary waterway water inlet is provided with a circle sealed groove, in described sealed groove, be provided with rubber seal, the height of described rubber seal is greater than the degree of depth of sealed groove.
Further, described tributary waterway water intake sidewall is provided with mounting hole, and described mounting hole is upper slice and lower combination and the common through hole forming.
Further, described tributary waterway water intake is quadrilateral, and described mounting hole comprises two and be positioned on tetragonal diagonal.
Further, in described mounting hole, be provided with steel bushing.
Further, described upper slice close main channel water outlet is provided with temperature transducer mounting hole.
Further, described upper slice and lower outer surface be provided with stiffening rib.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, can improve itself and the sealing effect of cylinder cap and the radiating effect of whole radiation system, meanwhile reduce product weight and simplify installation steps.

Embodiment
As Figure 1-4, a kind of cooling water pipe of engine of the utility model, comprise slice 1 and lower 2, upper slice 1 and lower 2 structure that is injection molding, upper slice 1 and lower 2 become a cavity by Vibration welding, cavity comprises a main channel 4 and at least one tributary waterway 3 being communicated with main channel 4, tributary waterway water intake 5 is positioned at lower 2, tributary waterway water intake 5 places are provided with a circle sealed groove 7, in sealed groove 7, be provided with rubber seal 8, the height of rubber seal 8 is greater than the degree of depth of sealed groove 7; Tributary waterway water intake 5 sidewalls are provided with mounting hole 9, mounting hole 9 for upper slice 1 and lower 2 in conjunction with the common through hole forming; Tributary waterway water intake 5 is quadrilateral, and mounting hole 9 comprises two and be positioned on tetragonal diagonal; In mounting hole 9, be provided with steel bushing 10; Upper slice 1 be provided with temperature transducer mounting hole 11 near main channel water outlet 6 places; Upper slice 1 and lower 2 outer surfaces be provided with stiffening rib 12.Upper slice 1 and lower 2 be the structure of nylon PA66 material molding and forming, the goods of comparing metallic material can loss of weight 50%, the product surface smoothness of nylon injection-molding is high simultaneously, outward appearance good; Upper slice 1 and the junction plane of lower 2 be provided with multiple boss, thereby melt both connected together at upper 1 boss during with lower 2 Vibration welding, form the cavity of an inner wall smooth, reduce coolant flow resistance, improve cooling effect; Because water-cooling tube length greatly increases product rigidity, therefore the appearance at product forms stiffening rib 12 when molding and forming; The effect of steel bushing 10 is further to connect upper slice 1 and lower 2, plays the effect of supporting construction bolt simultaneously.
The working procedure of this example: tributary waterway water intake 5 is tightly connected cylinder cap is communicated with tributary waterway 3 with cylinder cap, main channel water outlet 6 is tightly connected with water inlet of radiator; Flow through after the cooling liquid of cylinder cap absorbs cylinder heat and flow into the tributary waterway 3 of water-cooling tube and collect in main channel 4, in final inflow radiator, after heat radiation, enters next cool cycles.When installation, use bolt by the mounting hole 9 on tributary waterway water intake 5 outer walls, tributary waterway water intake 5 and cylinder cap to be tightly connected cylinder cap is communicated with tributary waterway 3, rubber seal 8 is highly greater than the degree of depth of sealed groove 7, be mounting plane 1mm～2mm that rubber seal 8 exceeds tributary waterway and go out water intake 5 places, rubber seal 8 produces deformation to reach sealing effect under the interaction force of bolt and cylinder cap attachment face, compared with the mode of this kind of sealing means and traditional use asbestos washer sealing, reduce the impact of installation process on sealing effect, simplify installation process, improve installation efficiency.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variation and improvement etc. of doing according to the utility model application range, within all should still belonging to patent covering scope of the present utility model.
