Embodiment
For the purpose, technological scheme and the advantage that make the utility model embodiment clearer, below in conjunction with the accompanying drawing among the utility model embodiment, technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment's main technical schemes is, on the respiratory cavity shell of gas and oil separating plant, increase heat sink design, improve the external heat dissipation potential of gas and oil separating plant, utilize the air ventilation in the vehicle driving to cool off, realize improving the purpose of oil gas separation by the condensation of strengthening oil gas, reach better Oil-gas Separation purpose.Below by the drawings and specific embodiments, the technical solution of the utility model is described in further detail.
Fig. 1 is the utility model gas and oil separating plant embodiment's a structural representation, and as shown in Figure 1, the gas and oil separating plant of present embodiment comprises respiratory cavity 11, suction port 12, air outlet 13, return opening 14 and mounting hole 15.
Wherein, this gas and oil separating plant can be fixed on the outside of engine body by mounting hole 15, suction port 12 can be connected with engine crankcase by pipeline, be used to make that the waste gas in the crankcase enters in the respiratory cavity 11 by this suction port 12, waste gas can carry out Oil-gas Separation in respiratory cavity 11.Air outlet 13 can be connected with the gas handling system of motor by pipeline, is used for the gas after the Oil-gas Separation is imported the gas handling system of motor.Return opening 14 can be connected with oil sump by pipeline, is used for the machine oil after the Oil-gas Separation is led the oil return drain pan again, reduces the consumption of machine oil and to the pollution of atmosphere.
The structure of the gas and oil separating plant of present embodiment and the main distinction of prior art are, have set up radiating fin 16 on the shell of respiratory cavity 11.Concrete, the metal construction that this radiating fin 16 can adopt heat exchange to use for example, can be iron, aluminium or copper etc.
This radiating fin 16 can be made by kinds of processes.For example, it can be the extruding radiating fin of aluminium matter, radiating fin adopts the material of aluminium, thermal conductivity is bigger, and radiating fin can be extruded fins, and each sheet fin all can come out from respiratory cavity 11 extruding by extrusion process, be connected fully with tube wall, form linear connection, can enlarge heat-conducting area, improve radiating efficiency.Perhaps, it also can pass through welding procedure, and radiating fin 16 is fixing with the shell welding of respiratory cavity 11, can adopt ferrous material, and welding manner can adopt spot welding.Perhaps, it also can adopt casting technique, with the radiating fin on respiratory cavity 11 and the shell thereof 16 structure one-step casting shaping as a whole.
In addition, this radiating fin 16 can be solid thermal conductive metal plate, also can be for hollow.When its when being hollow, it can be an one with respiratory cavity 11, can strengthen the tube wall of respiratory cavity 11, strengthens the body of respiratory cavity 11 and the area of contact of external agency, and heat exchange efficiency is improved.When concrete the making, radiating fin 16 can be perpendicular to the shell setting of respiratory cavity 11, and a plurality of described radiating fin can equidistantly be evenly arranged on the shell of described respiratory cavity, also can adopt other the form that is provided with.
Specifically describe the working principle of the gas and oil separating plant of present embodiment below:
The waste gas that contains atomizing machine oil, carbon dioxide etc. can enter from engine crankcase in the respiratory cavity 11 of this gas and oil separating plant by suction port 12, rotates mobile in respiratory cavity 11.Because oil is different with the density of gas, oil will gather under action of centrifugal force on the inwall of respiratory cavity 11, and inwall is got back to oil sump by return opening 14 in the action of gravity lower edge.Suction port 12 and air outlet 13 are designed in different heights, and towards different direction, and the gas after the separation can be led in the gas handling system of motor by air outlet 13 and participate in rekindling.Owing on the shell of respiratory cavity 11, increased radiating fin 16, after waste gas enters respiratory cavity 11 by suction port 12, except centrifugal action plays the function of Oil-gas Separation, because the air flows on the outer wall between a plurality of radiating fin 16 just produces condensation effects to the oil gas in the respiratory cavity 11, aggravated the aggtegation of oil mist particles in the oil gas, make Oil-gas Separation more thorough, thereby utilize condensation and centrifugal dual functions to reach the purpose of Oil-gas Separation.
The gas and oil separating plant of present embodiment, by on the shell of respiratory cavity, increasing heat sink design, and rely on the air flows between a plurality of radiating fin that the oil gas in the respiratory cavity is produced condensation effects, aggravated the aggtegation of oil mist particles in the oil gas, solved the bad problem of gas and oil separating plant separating effect of the prior art, make Oil-gas Separation more thorough, improved the effect of Oil-gas Separation.
