The aerial cooler of marine engine water
Technical field the present invention relates to a kind of motor intercooler, specifically is the aerial cooler of a kind of marine engine water.
The background technique diesel engine is the power core of present engineering machinery, generator set, large truck and steamer, in marine engine, in order to improve the engine power output performance, normal employing turbocharger compresses the back to air and carry out oil gas mixed combustion in being delivered to motor, to improve engine power performance.Air after turbosupercharger compression temperature generally about 200 degrees centigrade, the air of this range temperature pair with can not bring into play desirable power performance in the engine cylinder internal combustion, for this reason, extensively the way that adopts is the air after the compression to be carried out heat exchange cool, and used technology implementation means have all adopted the absolutely empty intercooler with the radiator fan type of cooling to cool off.The technological means of this absolutely empty intercooler is owing to adopt natural air as cold working medium, and the cabin inner air flow slowly causes temperature higher on the one hand, and air specific heat is less on the other hand, thereby causes final cooling effect undesirable.The present invention is directed to this problem, proposed with the seawater of outboard or river method as cooling working medium, invented the aerial cooler of a kind of marine engine water at the method that with seawater or river is cold working medium, it can reach and reduce the intercooler volume because of fan need not be installed.
Summary of the invention the present invention is directed to the problem and the present situation of present above-mentioned existence, and design has proposed a kind of new-type aerial cooler of marine engine water.
The present invention is adopted technological scheme to be by the problem of the above-mentioned solution of realization: the aerial cooler of marine engine water is mainly by radiator body, heat exchanging tube, the radiator suction port, the radiator air outlet is formed, it is characterized in that, the aerial cooler of marine engine water also comprises support, the support mounting hole, water inlet of radiator, radiator outlet, support is the arched surface structure, have 2 support mounting holes on the bi-side of support, radiator body is installed on the cradle top surface by bolt, support is embraced with bolt by the support mounting hole and is contained in the flywheel casing both sides, and radiator body is fixedly installed in directly over the flywheel casing by support.
Press such scheme, the air outlet of turbosupercharger connects by being connected sebific duct with the radiator suction port, and the radiator air outlet is connected with engine intake by connecting sebific duct; Water inlet of radiator is connected with pump outlet, and radiator outlet is connected with drain opening peculiar to vessel.
Press such scheme, the radiator body case is an ironcasting, and heat exchanging tube is that pipe sheet type structure and material are alloyed copper.
Press such scheme, the hot working fluid of the aerial cooler of marine engine water derives from the high temperature compressed air of turbosupercharger output, and hot working fluid flows in shell side; Cold working medium is that water pump draws next normal temperature seawater or river, and cold working medium flows in tube side.
The invention has the advantages that: owing to adopted normal temperature seawater or river is cold working medium, and cold working medium temperature is low relatively and stable, makes the heat exchange effect better and stable, and better effects and if engine combustion that pressurized air is cooled are more stable; Simultaneously, owing to fan need be installed, thus can effectively reduce the installing space of the peripheral power of motor, structure is compact more.
