TH33069B - Vents of hoods and formwork assemblies for casting of hoods - Google Patents

Abstract

The DC60 provides a louvre mounted in a cover plate that covers the ventilated material for optimum performance. Effectively prevent foreign matter from entering the cover plate. and ventilation Heat smoothly enters the cover plate, forming 84 fins in a shape that allows the distance between the outer ends of the fins to be located. Closer to each other is narrower than the distance between the inner ends of the fins that are close to each other. Provide a vent flap installed in a cover plate that covers the ventilated material for Effectively prevent foreign matter from entering the cover plate. and ventilation Heat smoothly enters the cover plate, forming 84 fins in a shape that allows the distance between the outer ends of the fins to be located. Closer to each other is narrower than the distance between the inner ends of the fins that are close to each other.

Claims (4)

1. A number of fins (84) flanged vents hood covers that are positioned in the free space. Inside the cooling air inlet (82) and dividing that space into air flow channels (83), several sections are arranged into the same unit as the hood. (80) where the straight line (L) is linked between the center of the outer end. Each channel is tilted from the center (C) of the cooling air inlet (82) to the resin cover (80). Synthetic, which has a cooling air inlet (82) with its inner end opening to the object (69) to be cooled. And has the outer end of It opens to the outside and covers the said object (69) to be cooled. It is unique that each fin (84) is made up of the main part of the fin (84a) facing the side approaching the object (69) to be cooled from the outer end of the internal space. Of air inlet The cooling air inlet (82) is and is tilted away from the center line (C) of the said cooling air inlet (82) and the outer end is connected in an even way to the surrounding edge. At the outer end of the aforementioned cooling air inlet (82), and the protrusion (84b), angled to the outer end of the dorsal fin (84a), is towed evenly. Which will be filed at The sides of the fins are close to each other (84) and are formed into shapes that allow the distance between the fish outside of The adjacent fins (84) narrower than the distance between the inner ends in the space inside the air inlet. Cooling (82) 2. The engine, which has a vented flake cover, as described in Clause 1, is screwed to the end wall (36a) of the generator cover. The binder is located on the front side of the engine housing (32,33), characterized by that the aforementioned object (69) has a cooling fan for air intake. For cooling through the cooling air inlet (82) and the said object (69) to be cooled, it is positioned between the facing pages between the object (69) to be cooled and the Pai wall. (36a) is located on the outside of the end wall (36a) of the generator shield (36), the cooling fan (70) and the aforementioned object (69) to be cooled. Such a cooling fan (70) is attached to the end of the crankshaft 31) through which the rod through the through-hole (87) located at The end wall (36a) is said to and is made up between the inner face of that through hole (87) and the outer face of the The tip of the crankshaft (31) is an annular gap that contacts the inside of the cover. Attach the aforementioned airway scales (80) 3. Engines as defined in claim 2, are characterized by the fact that the object to be cooled is a radiator (69) for water-cooled cooling for such engine cooling fan (70). It is positioned between the radiator (69) and the alternator (68) within the aforementioned generator cover (36), along the axis of the aforementioned crankshaft (31), whose axis runs along the plane. Horizontal The said intake flanges (80) are positioned in such a way that they face the said cooling air inlet (82) on the outside of the aforementioned radiator (69) along the crankshaft axis (31). ) Such 4. Formwork assembly for forming the cover plate for the assembly of the cover plate. Attach the vent scale in claim 1, which is unique in that it includes the first mold part (91), with the first mold part (91a) for the outer face forming. And the end face of the main part of the flanges (84a) together with the anterior and distal face of the aforementioned (84b) and the second formwork (92) with the second casting (92a) for the Forming the inner face and the inner end face of the said main part of the fin (84a) together with the inner face of the overhang (84b).
