Abstract
The utility model discloses a take turbo charger of adiabatic volute of air gap, including the volute body, the volute body constitute in outer metal sheet (1) welding by inner layer metal lamellar body (2) that form the runner and cladding, just inner layer metal lamellar body (2) and outer metal sheet (1) between be equipped with the air intermediate layer, inner layer metal lamellar body (2) inner chamber a plurality of main entrances (4) and a plurality of branched passage (5) that correspond exhaust manifold connector department that are equipped with volute runner (3) in proper order, are linked together with volute runner (3). The utility model discloses adiabatic effectual, with low costs, can satisfy the lightweight demand.
Description
Technical field
The utility model relates to automobile field of turbochargers, particularly a kind of turbosupercharger with the adiabatic volute of air gap.
Background technique
Turbosupercharger be utilize motor to discharge waste gas inertial force to promote the turbine in turbine chamber, turbine drives again coaxial impeller, the air that impeller force feed is sent here by air-strainer pipeline, makes it supercharging and enters cylinder.Be equipped with the automobile of turbosupercharged engine, not only on power and these performance of power, far be more than the automobile product of same discharge capacity, more in the using process of reality can with discharge capacity on be equal to than the automobile of a grade on oneself, not only do not need to buy huge discharge automobile in order to pursue two-forty to spend more expense, and noise during engine operation is less.Adopt the lighter motor of deal to reduce complete vehicle weight in addition, minimizing oil consumption benefits especially.In addition, polluting the today be on the rise, protection of the environment is extremely urgent, and environmental protection, energy-conservation emission standard are also prior advantages of turbosupercharger, therefore, adopt turbosupercharger to be trend of the times in family-sized car.For the small displacement family-sized car that market share is huge, require its turbosupercharger lightweight, with low costization.
Volute is the main part that motor is connected with pressurized machine, and faces the working environment of High Temperature High Pressure, and therefore the thickness of volute can not do very thin.Traditional turbosupercharger, generally all uses the volute of full casting, guides back blast turbine.And the volute entirely cast needs to use a large amount of metallic material, the volute especially with enmgine exhaust, can make the metallic material of needs be multiplied; Exactly because also like this, the lightweight of volute is also a difficult problem.Meanwhile, because metal has good heat-conducting property, using the volute of full casting to be very easy to by the heat conduction of engine exhaust to pressurized machine periphery, is also a challenge to the part life of pressurized machine periphery.Thicker volute can make raw material use amount more, and pressurized machine is heavier, does not also meet current cost pressure and light-weighted requirement.
Summary of the invention
Technical problem to be solved in the utility model is: provide that a kind of insulation effect is good, cost is low, can meet the turbosupercharger of the adiabatic volute of the band air gap of lightweight demand.
The technical scheme in the invention for solving the above technical problem is: a kind of turbosupercharger with the adiabatic volute of air gap, comprise volute body, described volute body by forming the inner layer metal lamellar body of runner and being coated on outer field outer layer metal lamellar body and being welded to form, and is provided with air blanketing between described inner layer metal lamellar body and outer layer metal lamellar body; Described inner layer metal sheet intracoelomic cavity is provided with volute flow passage, multiple branched bottoms with multiple main passage that volute flow passage is connected and corresponding gas exhaust manifold connection mouth place successively.
Compared with prior art, the utility model has the advantage of: the volute body of the turbosupercharger of the adiabatic volute of this band air gap is by forming the inner layer metal lamellar body of runner and being coated on outer field outer layer metal lamellar body and being welded to form, and be provided with air blanketing between inner layer metal lamellar body and outer layer metal lamellar body, a natural air blanketing is defined between inner layer metal lamellar body and outer layer metal lamellar body, because the capacity of heat transmission of air will far below metal, because the heat of engine exhaust is also not easy to be delivered to pressurized machine outside, serve adiabatic effect to a certain extent.Inner layer metal sheet intracoelomic cavity is provided with volute flow passage, multiple branched bottoms with multiple main passage that volute flow passage is connected and corresponding gas exhaust manifold connection mouth place successively.That is the inner layer metal lamellar body of this practicality constitutes new volute flow passage or gas exhaust manifold, and outer layer metal lamellar body is then wrapped in outside it, defines protective layer, and insulation effect is good, cost is low, can meet lightweight demand.
As preferably, the corresponding gas exhaust manifold connection mouth place of described volute body is welded with multiple flange for installing.
As preferably, the side of described volute body is welded with the joint for being connected with outlet pipe, and is welded with link between described joint and described inner layer metal lamellar body.
As preferably, the quantity of described branched bottom is four, and the outlet port correspondence of described branched bottom is welded with four flanges for installing.
