Description
Technical field
This utility model relates to turbo-charger technical field, particularly a kind of turbocharger volute.
Background technology
Turbocharger is used for improving the efficiency of internal combustion engine, obtains waste gas stream by turbine in turbocharger
Kinetic energy and the kinetic energy of waste gas stream via the axle of turbine and the common mistake of compressor for air fuel is mixed
Compound press-in internal combustion engine.The fixing work of internal combustion engine can be filled by this way with larger amount of mixture
Volume, thus can realize bigger lift when burning and therefore realize bigger engine power.
The axle of turbocharger generally by sliding supported condition in turbocharger housing, thus just exist
A large amount of frictional energies of hot form at release in the bearing receiving portion of turbocharger housing, existing turbine increases
Although the housing of depressor is by pouring the preferable heat conductivity that has that metal constitutes, but costly, improves and produce
Cost.
Summary of the invention
This utility model technical issues that need to address are by arranging helical form cooling tube in cooling cavities
Extend the gases at high pressure time in cooling cavities, make that coolant contacts with gases at high pressure more fully, from
And ensure that temperature when gases at high pressure temperature enters in electromotor meets the requirements；A kind of turbocharger is provided
Spiral case.
For solving above-mentioned technical problem, structure of the present utility model includes chassis body, described casing master
Offer on body the first intake channel, the second intake channel, the 3rd intake channel, the first air outlet passage,
Two air outlet passage, cooling cavities, coolant channel and electromotor install cavity, the first described intake channel
Being connected with one end of the second intake channel, the other end of the second described intake channel is connected with cooling cavities
Logical, described cooling cavities is installed cavity by the 3rd intake channel with electromotor and is connected, described cooling
Agent path is connected with cooling cavities, and the second described air outlet passage is pacified with electromotor by the first air outlet passage
Body of behaveing affectedly is connected, and described chassis body is further opened with air inlet branch road, described air inlet branch road and first
Intake channel is connected, and is provided with electromagnetic valve and installs cavity in described air inlet branch road.
Further: compressor impeller, the second described air outlet passage are installed in the first described intake channel
Turbine wheel, described compressor impeller and turbine wheel coaxial linkage are inside installed.
Further: described cooling cavities is rectangle hollow cavity, the both sides of described cooling cavities are respectively opened
Being provided with a through hole, described cooling cavities is connected with coolant channel by the through hole of both sides, described
Being provided with helical form cooling tube in cooling cavities, the two ends of described helical form cooling tube are through cooling cavities
Sidewall is connected with the second intake channel and the 3rd intake channel respectively.
After using said structure, this utility model extends by arranging helical form cooling tube in cooling cavities
The gases at high pressure time in cooling cavities, make that coolant contacts with gases at high pressure is more abundant, thus really
Protect temperature when gases at high pressure temperature enters in electromotor to meet the requirements；And the design also has structure letter
Single, the easily fabricated and advantage of practicality and high efficiency.
