Abstract

The utility model discloses a pressurized airflow cooling device for cooling a waterway side cover. The pressurized airflow cooling device is characterized by comprising a housing and three ring-shaped waterway pipes arranged in the housing; each waterway pipe is provided with a cooling water inlet; the cooling water inlets are formed in the side wall of the housing; two adjacent waterway pipes are communicated through a radiating water pipe; a cooling air inlet is formed in one end of the housing, and a cooling air outlet is formed in the other end of the housing. The housing is arranged on the position of a waterway side cover outside an engine body, is as long as the engine body, and replaces a waterway and a side cover of an original engine; the cooling air inlet is communicated with a mechanical pressurizer; the cooling air outlet is communicated with an exhaust pipe of an engine; the three cooling water inlets are communicated with the waterway of the engine. The pressurized airflow cooling device does not influence the low-speed power output of the engine, and can lower the exhaust air temperature, thereby reducing the heating to inlet air in the engine during the pressurizing process of a turbocharger.

Description

A kind of cooling water channel limit lid pressurized air stream cooler

Technical field

The utility model relates to engine art, especially a kind of cooling water channel limit lid pressurized air stream cooler.

Background technique

The existing motor with pressurized machine, turbosupercharger is wherein to utilize engine exhaust to promote turbine to drive gas compressor to engine booster, and turbosupercharger is transmitted on metal shell affecting function of the engine after air-flow heating by waste-gas heat in entering gas compressor process pressurization gas; When motor is not when running up, cannot open turbine supercharging, cannot be to engine turbine supercharging, turbosupercharger is a kind of obstruction to the air inlet of motor, affects the output of low engine speed power; The raising that turbosupercharged engine brings engine power due to the lifting of cylinder pressure and the lifting of fuel oil, the problem of simultaneously thereupon bringing be engine temperature higher than natural intake engine, need to improve the heat dispersion of motor.

Model utility content

The purpose of this utility model is for the deficiencies in the prior art, and provide a kind of cooling water channel limit to cover pressurized air stream cooler, this pressurized air stream cooler do not affect low engine speed power output, can reduce delivery temperature, thereby alleviate turbosupercharger heating to engine charge in pressurization.

The purpose of this utility model is to realize by following technological scheme:

A cooling water channel limit lid pressurized air stream cooler, comprises housing and is arranged on three water annulus pipes in housing, each water pipe is equipped with cooling water inlet, and cooling water inlet is arranged on the sidewall of housing; Between adjacent water pipe, by heat dissipation pipe, be communicated with; One end of housing is cooling air inlet, and the other end is cooling air outlet.

Between described water pipe and inner walls, leave ventilation voids.

Described heat dissipation pipe is provided with radiating fin or radiating wire.

Described housing is arranged on the water channel Bian Gai position outside engine body, housing and engine body are isometric, the water channel and the Bian Gai that replace former motor, cooling air inlet is communicated with mechanical supercharger, cooling air outlet is communicated with waste pipe, and three cooling water inlets are communicated with the water channel of motor.

Adopt above-mentioned technological scheme, the air-flow that mechanical supercharger produces is first given engine radiating, then to turbocharger of motor, make to promote air-flow again, promote turbosupercharger to engine booster together with engine exhaust, low engine speed turbosupercharging also can complete turbosupercharging, and more radiating airflow enters outlet pipe, and engine radiating air-flow is lower than engine exhaust, can reduce delivery temperature, thereby alleviate turbosupercharger heating to engine charge in pressurization.

Embodiment

Below in conjunction with drawings and Examples, the utility model content is further elaborated, but is not to restriction of the present utility model.

Embodiment:

With reference to Fig. 1, a kind of cooling water channel limit lid pressurized air stream cooler, comprises housing 1 and is arranged on three water annulus pipes 2 in housing 1, each water pipe 2 is equipped with cooling water inlet 4, and cooling water inlet 4 is arranged on the sidewall of housing 1; Between adjacent water pipe 2, by heat dissipation pipe 3, be communicated with; One end of housing 1 is cooling air inlet 5, and the other end is cooling air outlet 7.

Between water pipe 2 and housing 1 inwall, leave ventilation voids, so that the cooling of water pipe.

Heat dissipation pipe 3 is provided with radiating fin 6 or radiating wire, so that cooling.

With reference to Fig. 2, housing 1 is arranged on the water channel Bian Gai position outside engine body, housing 1 is isometric with engine body, the water channel and the Bian Gai that replace former motor, cooling air inlet 5 is communicated with mechanical supercharger 8, cooling air outlet 7 is communicated with waste pipe 9, and three cooling water inlets 4 are communicated with the water channel of motor.

During engine operation, crank pulley is by the 8 running work of belt driving mechanical pressurized machine, the air-flow that mechanical supercharger 8 produces enters in this cooler from cooling air inlet 5, the air-flow of cooler of flowing through is taken away water pipe 2 and heat dissipation pipe's 3 heat, with the air-flow of heat, from cooling air outlet 7, at the suction port of turbosupercharger 11, enters outlet pipe 9.Impeller gas compressor 10 is communicated with supercharging feed channel 12, the air-flow that mechanical supercharger 8 produces first dispels the heat and enters engine exhaust pipe 9 again to motor, promoting turbosupercharger 11 work together with engine exhaust can be when low engine speed be worked, turbosupercharger 11 also can be opened as engine booster, strengthen the power of calming the anger of mechanical supercharger 8, the one, can improve heat dispersion, the 2nd, in the time of can improving low engine speed, can open turbine pressurized machine 11 be engine turbine supercharging, the air-flow strengthening can reduce the temperature in engine exhaust pipe 9, outlet pipe 9 temperature reduce can allow turbosupercharger 11 in pressurization, alleviate heating to air inlet.
