Abstract
The invention relates to an overhead intercooler for a diesel engine. The overhead intercooler comprises an air inlet pipe, a first diversion chamber, a heat exchanger, a second diversion chamber, an air outlet pipe and a support which is fixed on a cylinder cover of the diesel engine; the air inlet pipe is connected with an inlet end of the first diversion chamber; an outlet end of the first diversion chamber is connected with an inlet end of the heat exchanger; an outlet end of the heat exchanger is connected with an inlet end of the second diversion chamber; an outlet end of the second diversion chamber is connected with the air outlet pipe; the overhead intercooler also comprises a water circulation device which comprises an annular water pipe, a water tank and a water pump; the annular water pipe sleeves the heat exchanger; one end of the annular water pipe is connected with the water tank; the other end of the annular water pipe is connected with one end of the water pump; the other end of the water pump is connected with the water tank. According to the overhead intercooler for the diesel engine, the heat exchange efficiency of the intercooler can be improved.
Description
Technical field
The present invention relates to use for diesel engine overhead intercooler.
Background technique
In order to improve power character and the fuel economy of diesel engine, modern diesel engine is generally equipped with turbosupercharger, and its effect compresses the air participating in burning, the power of diesel engine so both can have been made to be improved, can reduce again the fuel consume of complete machine.But due to the compression through turbosupercharger, the temperature of air can be elevated to more than 150 DEG C, the air density participating in burning greatly reduces, and is unfavorable for so again diesel engine work.In order to reduce the intensification of the rear air of compression, modern supercharged diesel engine is provided with air intercooler (intercooler), and this diesel engine is called turbocharged and intercooled diesel engine.The intercooler of traditional design, is arranged in car load front end cooling water tank anterior, being cooled by pressurization gas windward when relying on gas garage to walk.But the intercooler of this structure needs to connect very long inlet, outlet air pipe line on car load, takies very large space, makes intercooler system cost very high.Simultaneously because intercooler stops cooling water tank, have impact on the radiating effect of car load, easily cause again diesel engine water temperature higher; The sealing of intercooler turnover air pipe is also difficult to ensure in addition, and easily leak air phenomenon, causes diesel engine fault, bring hidden danger to traffic safety.
A kind of use for diesel engine overhead intercooler is disclosed in prior art, it comprises heat exchanger, support, diesel engine cylinder cover, diversion chamber, suction tude and steam outlet pipe, heat exchanger support is fixed on the top of diesel engine cylinder cover, import and the outlet end of heat exchanger are equipped with diversion chamber, suction tude and steam outlet pipe are connected with respective diversion chamber respectively, described heat exchanger is air cooling fin tubular type, participate in burning air and fin tube outside cool air carry out exchange heat.The heat exchange efficiency of this intercooler is not high, reason is, in the internal-combustion engine bin of automobile, due to narrow space, after Cang Gai covers, the passage that can enter into the air in storehouse is located air-inlet grille substantially, therefore, be placed in by intercooler after above diesel engine cylinder cover, air is very limited to the cooling of fin, thus, cause the situation that heat exchange efficiency is not high.
Summary of the invention
For above-mentioned technical problem, main purpose of the present invention is to provide use for diesel engine overhead intercooler, and the present invention can improve the heat exchange efficiency of intercooler.
The technological scheme solved the problems of the technologies described above is as follows:
Use for diesel engine overhead intercooler, comprise suction tude, first diversion chamber, heat exchanger, second diversion chamber, steam outlet pipe and be fixed on the support that cylinder of diesel engine covers, suction tude is connected with the entrance point of the first diversion chamber, the outlet end of the first diversion chamber is connected with the entrance point of heat exchanger, the outlet end of heat exchanger is connected with the entrance point of the second diversion chamber, the outlet end of the second diversion chamber is connected with steam outlet pipe, also comprise a water circulator, this water circulator comprises annular conduit, water tank and water pump, annular conduit cover on heat exchangers, one end of annular conduit is connected with water tank, the other end of annular conduit is connected with one end of water pump, the other end of water pump is connected with water tank.
Further, described annular conduit is spirally wound around on heat exchangers.
Have employed such scheme, also comprise a water circulator, this water circulator comprises annular conduit, water tank and water pump, annular conduit cover on heat exchangers, one end of annular conduit is connected with water tank, and the other end of annular conduit is connected with one end of water pump, and the other end of water pump is connected with water tank.By the cooling water of water pump to annular conduit input circulation, because heat exchanger transfers heat to annular conduit by thermaltransmission mode, when the cooling water of circulation circulates in annular conduit, the heat come by heat trnasfer is taken away, like this, intercooler and compressed-air actuated heat exchange efficiency is made greatly to promote.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
1 is suction tude, and 2 is the first diversion chamber, and 3 is heat exchanger, and 2a is the second diversion chamber, and 4 is steam outlet pipe, and 5 is support, and 6 is annular conduit, and 7 is water tank, and 8 is water pump,
