Description
Technical field
The invention belongs to engine cooling technical field, be specifically related to a kind of intercooler of motor.
Background technique
Diesel engine is the core drive of automobile-used, engineering machinery and generating at present, is transported to again in motor after adopting turbosupercharger to compress air and carries out air-fuel mixture burning, and be effective measures that improve engine power output.But air temperature is after compression up to 200 DEG C, high temperature air density is relatively little, enters air quality in cylinder few, and air-fuel mixture is of poor quality, causes in-cylinder combustion quality to worsen, engine performance index error.How to improve in-cylinder combustion effect, conventionally way is that air-cooler (being intercooler) is installed after pressurized machine, the gas after compression is carried out cooling, improves density of the induced air.
According to the difference of cooling medium, intercooler can be divided into air-air intercooler and water-air inter cooler.Air-air intercooler is to utilize ambient air to carry out cooling to the air by intercooler.Water-air inter cooler is that to utilize cooling water to carry out the air by intercooler cooling, and it comprises the air chamber at heat radiation core body and two ends, and heat radiation core body is mainly made up of runner pipe and radiating fin.
Water-air inter cooler is to utilize recirculated cooling water to carry out cooling to the air by intercooler.Water-cooled intercooler comprises heat radiation core body and intercooler housing, and heat radiation core body is mainly made up of runner pipe and radiating fin.On the housing of water-cooled intercooler, be connected with circulating pipe, cooling water is constantly circulation under the effect of water pump, by the pressure-air cooling in runner pipe.Water-cooled intercooler is generally used on the vehicle and large-duty engine of engine in front of rear wheel mid-engine or postposition.
Traditional water-air inter cooler is designed to a hexahedron, a side air inlet, and respective side is given vent to anger, opposite side water inlet, respective side water outlet, this intercooler volume is large, Heavy Weight, efficiency are low.
The model utility of application number 201120438698.7 discloses a kind of intercooler, the suction port and the air outlet that comprise radiating core and be communicated with radiating core fluid, be communicated with turnover air cavity in one end of radiating core, the other end is communicated with transfer chamber, turnover air cavity is divided into air-inlet cavity and outlet chamber by internal partition, and air-inlet cavity and outlet chamber are directly communicated with.Suction port and air outlet are arranged in to same one end of radiating core, can solve the space Layout Problem of part vehicle.Hot air enters air-inlet cavity by suction port in addition, then after radiating core, transfer chamber, radiating core and outlet chamber, then enters motor by air outlet, has indirectly extended the circulation distance of hot air, thereby has improved the utilization ratio of radiating core.But this intercooler exists that cooling water flow path is little, the operating time is short, the problem that heat exchange efficiency is low.
Summary of the invention
In order to overcome, the intercooler volume of above-mentioned prior art is large, quality heavy, inefficient technical problem, the invention provides a kind of high efficiency intercooler.
Technological scheme of the present invention: a kind of intercooler, comprise compressed air inlet port 1, pressurized air air-inlet cavity 2, heat radiation core body 3, coolant outlet 4, cooling water intake 5, in cold rear air cavity 6, in cold rear air outlet slit 7, cooling water chamber 9, there are intake tunnel 12 and exhalant canal 13 in described heat radiation core body 3 inside, intake tunnel 12 is connected by cooling water chamber 9 with exhalant canal 13, described compressed air inlet port 1 with in cold rear air outlet slit 7 lay respectively at the relative both sides of intercooler, it is characterized in that: coolant outlet 4 and cooling water intake 5 are positioned at the homonymy of intercooler, intake tunnel 12, cooling water chamber 9 and exhalant canal 13 are " U " type in heat radiation core body 3 inside and arrange.
The present invention compared with prior art has following beneficial effect: intercooler provided by the invention has increased the flow path of cooling water in intercooler, be conducive to cooling water and pressurized air and carry out sufficient heat exchange, can effectively improve the cooling capacity of intercooler, for cooling identical high temperature air, intercooler volume reduces 10%, weight reducing 15%, efficiency improve 20%.
