Problems solved by technology
[0005] 1. Centrifugal fan blades replace axial flow fan blades, which cannot produce the required air volume for heat dissipation;
[0006] 2. There are no reinforcing ribs on the centrifugal fan blades. At high speeds, the fan blades are prone to backward deformation, resulting in a drop in pressure and air volume.
[0007] 3. The wind bucket is easily deformed and damaged;
[0008] 4. Set the air outlet, the air outlet needs to be additionally equipped, which increases the manufacturing cost

Embodiment Construction
[0027] As shown in the figure, a kind of oxygen supply heat radiation supercharging device of the present invention comprises casing part and wind vane part, and casing part comprises front casing 1 and rear casing 13, and front casing 1 and rear casing 13 surface Reinforcing ribs 12 are provided, and the reinforcing ribs 12 include annular reinforcing ribs and radial reinforcing ribs. The annular reinforcing ribs and radial reinforcing ribs are arranged alternately. The setting of reinforcing ribs 12 makes the probability of thermal deformation of the entire casing smaller. , the front half air outlet 11 and the rear half air outlet 18 are respectively fixedly connected to the front casing 1 and the rear casing 13, and the front half air outlet 11 and the rear half air outlet 18 are combined to form an air outlet, so that no additional An air outlet is added to save costs. A groove ring 10 and a convex ring 17 are respectively arranged on the outer side walls of the front casi...

The invention provides an oxygen supply heat dissipation supercharging device, belonging to the technical field of the internal combustion engine. The device comprises a frame and fan blades arranged in the frame; wherein the frame comprises a front frame and a rear frame which are provided with a strengthening rib on the surfaces respectively; the front frame and the rear frame are combined and connected to form an annular ventilation duct; the fan blades are formed by a wind wheel, an axial fan blade and a centrifugal fan blade which are connected from the inside to the outside; a stator isarranged in the wind wheel; a reinforcing rib of the wind wheel is arranged between the inside wall of the wind wheel and the stator in a fitting manner; the axial fan blade is fixedly connected withoutside of the wind wheel, and is fixedly connected with the centrifugal fan blade through a matched circular ring; a triangular reinforcing rib is arranged between the centrifugal fan blade and the circular ring; the wind wheel and the axial fan blade are positioned in the inner circle of the annular ventilation duct; and the centrifugal fan blade is positioned in the annular ventilation duct. The device is formed by combining the front frame and the rear frame which are provided with air outlets, and is assembled a draught fan which is integrally formed by the wind wheel, the axial fan blade and the centrifugal fan blade in the frame, and is added the reinforcing ribs on each key position, so that the device has better oxygen supply, heat dissipation and supercharging, and has longer service life.
Description
technical field [0001] The invention belongs to the technical field of internal combustion engines, and in particular relates to an oxygen supply, heat dissipation and supercharging device installed on an internal combustion engine. Background technique [0002] There are currently two types of air intake for diesel engines: naturally aspirated and turbocharged. Both techniques have different drawbacks. [0003] Due to insufficient intake pressure, naturally aspirated diesel engines work under anoxic conditions most of the time, which are prone to black smoke and poor power performance, and are currently being eliminated by supercharged engines; There are three difficult problems to overcome: 1. Turbine hysteresis, because the turbine has a certain inertia, the amount of exhaust gas discharged when the engine speed is low is not enough to drive the turbine to rotate, and the supercharger cannot play a role, so when rapid acceleration is required, There will be a short dela...
