Technical field
The present invention relates to a kind of multi-cylinder engine water temperature cooling air inlet boosting device.
Background technology
At present, the cooling of multi-cylinder engine water temperature, by stand alone type cistern circulated water, fan coolling, for improving the power of internal combustion engine, internal combustion engine uses plenum system.The plenum of internal combustion engine, waste gas by gas extraction system drives axial flow blower high speed rotating, supercharging air is made to enter cylinder, for reducing the exhaust high temperature damage to supercharger, multiplex middle cold water storage cistern system reduces temperature, the most not only cost is high, and when internal-combustion engine rotational speed is low, not only few because of capacity, supercharger speed does not reaches, have impact on the pressurized effect of gas handling system, and have influence on the cooling-down effect of middle cold water storage cistern refrigeration system, cause the damage of supercharger, owing to plenum system cost is high, maintenance cost height and disadvantages described above, the four following internal combustion engines of cylinder the most do not use charger boost means.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of low cost, effective internal combustion engine water temperature cooling air inlet boosting device, solves the water temperature cooling plenum problem of the four following internal combustion engines of cylinder.
For solving above-mentioned technical problem, the present invention includes engine cycle water cooling fan, described cooling fan has fan hub, fan hub is provided with internal fan blade, it is structurally characterized in that wind scooper in internal fan blade outer is provided with annular, interior wind scooper outer peripheral face is provided with external fan blade, fan blade and interior wind scooper peripheral ring are provided with outer wind scooper outside, supercharging air chamber is formed between inside and outside wind scooper, outer wind scooper is provided with air inlet and gas outlet, on described air inlet, air strainer is installed, connect with the cylinder air inlet of multi-cylinder engine through intake elbow after air filter being installed on described gas outlet.
Described outer wind scooper include radiator grille, rear mask and connect before and after the ring cover of face shield outer, described rear mask and ring cover are integrative-structure, and described radiator grille is dismantled and assembled structure relative to ring cover.
Described outer wind scooper is axially external with external fan blade outer and two is provided with gap, and this gap is 13 millimeters.
The quantity of described internal fan blade is 4 10, and the quantity of described external fan blade is 10 30.
Described interior wind scooper is circle shape, and described outer wind scooper radial cross-sectional shape is U-shaped.
After using said structure, due to wind scooper in being provided with annular in internal fan blade outer, interior wind scooper outer peripheral face is provided with external fan blade, fan blade and interior wind scooper peripheral ring are provided with outer wind scooper outside, fan is fabricated to a composite fan, by internal fan blade, air is blowed to water tank, cooling circulating water, reduce the temperature of IC engine airframe, each cylinder of internal combustion engine will be entered after supercharging air by external fan blade, owing to after supercharging, fresh air makes each cylinder intake air quantity of internal combustion engine sufficient, cylinder fuel burning is fully, improve the power of internal combustion engine, reduce exhaust emission degree, protect environment.The present invention, compared with the type using supercharger, owing to decreasing the axial flow blower involved great expense and middle cold water storage cistern refrigeration system, greatly reduces cost, decreases maintenance cost.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is described in further detail:
Fig. 1 is the structural representation of the present invention；
