Description
Technical field
The invention belongs to cold technical field of temperature control in engine charge, more particularly to a kind of cryogenic gas bypass type temperature
Control air inlet pipe.
Background technology
Engine can operationally produce very high temperature, and engine is typically mounted in closed space, so
Temperature can be caused in enging cabin apparently higher than environment temperature.When ambient temperature is high, such as, in hot summer, start
Machine is deteriorated with extraneous heat exchange, and natively ambient temperature is high in addition for the engine of high temperature, directly results in engine charge
Temperature is too high, can at this time cause many problems, such as dynamic property is poor, less economical, combustion knock etc., can cause when serious
Parking, or even engine are scrapped.
The content of the invention
The technical problems to be solved by the invention are：A kind of cryogenic gas bypass type temperature control air inlet pipe is provided, to solve hair
Motivation intake air temperature height causes the technical problem of various faults.
In order to solve the above technical problems, the technical scheme is that：Cryogenic gas bypass type temperature control air inlet pipe, including enter
Offered on tracheae body, the air inlet tube body and be additionally provided with cryogenic gas on air inlet and exhaust outlet, the air inlet tube body
Entrance and cryogenic gas outlet, the air inlet pipe body interior are provided with cryogenic gas pipeline, and the cryogenic gas pipeline connects respectively
Logical cryogenic gas entrance and the cryogenic gas outlet.
As an improvement, the cryogenic gas pipeline includes helical pipe and the rectilinear duct linked together, described
Rectilinear duct is located inside the helical pipe.
As an improvement, the air inlet tube body includes housing and the cover plate positioned at the shell one end, the air inlet
Mouth and the exhaust outlet are respectively arranged on the two side of the housing, and cryogenic gas entrance and the cryogenic gas outlet is located at described
The outside of cover plate, the cryogenic gas pipeline is located at the inner side of the cover plate.
As an improvement, the cryogenic gas is the liquefied natural gas after vaporization or the compressed natural gas after decompression.
Employ after above-mentioned technical proposal, the beneficial effects of the invention are as follows：
Because the air inlet tube body of cryogenic gas bypass type temperature control air inlet pipe is provided with cryogenic gas entrance and cryogenic gas
Outlet, the air inlet pipe body interior is provided with cryogenic gas pipeline, and the cryogenic gas pipeline is respectively communicated with the cryogenic gas
Entrance and cryogenic gas outlet, thus when Engine Inlet Temperature is high, drawn cryogenic gas by cryogenic gas entrance
Enter cryogenic gas pipeline, heat exchange is carried out with the intrinsic high-temperature gas of air inlet pipe, reach the effect of reduction Engine Inlet Temperature
Really, the cryogenic gas after heat exchange is exported by cryogenic gas and discharged；When Engine Inlet Temperature is low, blocked by outside control
The supply of cryogenic gas, so as to be unlikely to make the cold start-up of the too low influence engine of intake air temperature.
The cryogenic gas bypass type temperature control air inlet pipe that the present invention is provided, by introducing cryogenic gas, reduces engine and enters
Temperature degree, it is ensured that engine causes in high environment temperature, high cabin temperature etc. under the high environment of Engine Inlet Temperature, engine
Dynamic property and reliability and good economy.
Because the cryogenic gas pipeline includes the helical pipe linked together and rectilinear duct, thus pass through helix tube
Road can increase the circulation area of cryogenic gas so that good effect of heat exchange.
Because the air inlet tube body includes housing and the cover plate positioned at the shell one end, thus facilitate manufacture and pacify
Dress.
Brief description of the drawings
Fig. 1 is the structural representation of the embodiment of the present invention；
In figure：1- air inlet tube bodies, 11- housings, 12- cover plates, 2- air inlets, 3- exhaust outlets, 4- cryogenic gas entrances, 5-
Cryogenic gas is exported, 6- cryogenic gas pipelines, 61- helical pipes, 62- rectilinear ducts.
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
As shown in figure 1, a kind of cryogenic gas bypass type temperature control air inlet pipe, including air inlet tube body 1, on air inlet tube body 1
Offer and cryogenic gas entrance 4 and cryogenic gas outlet 5, air inlet pipe are additionally provided with air inlet 2 and exhaust outlet 3, air inlet tube body 1
The inside of body 1 is provided with cryogenic gas pipeline 6, and cryogenic gas pipeline 6 is respectively communicated with cryogenic gas entrance 4 and cryogenic gas outlet 5.
In order to obtain good heat transfer effect, it is preferred that cryogenic gas pipeline 6 includes the helical pipe 61 linked together
With rectilinear duct 62, rectilinear duct 62 is located inside helical pipe 61, so can increase cryogenic gas by helical pipe 61
Circulation area.In the present embodiment, the connection cryogenic gas of helical pipe 61 entrance 4, the connection cryogenic gas of rectilinear duct 62 goes out
Mouth 5.Certainly, alternatively, it would however also be possible to employ the connection cryogenic gas of helical pipe 61 outlet 5, rectilinear duct 62 connects
Connect cryogenic gas entrance 4.
Manufacture and install for convenience, in the present embodiment, above-mentioned air inlet tube body 1 includes housing 11 and positioned at housing 11
The cover plate 12 of one end, air inlet 2 and exhaust outlet 3 are respectively arranged on the two side of housing 11, and exhaust outlet 3 has four, and cryogenic gas enters
Mouth 4 and cryogenic gas outlet 5 are located at the outsides of cover plate 12, and cryogenic gas pipeline 6 is located at the inner side of cover plate 12.
