Abstract

The utility model relates to an outboard machine with a cooling assembly. The outboard machine comprises an engine; the engine comprises the cooling assembly; the cooling assembly comprises an engine driving shaft, an impeller, a water pump inner container, an underwater device and a water pipe; the water pump inner container is arranged in the underwater device and is communicated with the outside of the underwater device; an eccentric hole is arranged on the water pump inner container; the engine driving shaft penetrates through the eccentric hole; the impeller is arranged on the engine driving shaft and is positioned in a cavity of the water pump inner container; a water outlet is arranged on the water pump inner container and is close to the eccentric hole; the outer radius of the impeller is larger than the maximum distance from the center of the eccentric hole to the inner wall of the water pump inner container, and the thickness of the impeller is consistent with that of the inner cavity of the water pump inner container; the water outlet is connected with one end of the water pipe; and the other end of the water pipe is connected with the engine. According to the scheme, the outboard machine has the advantages that the water-carrying capacity of a cooling device is high owing to the thickened impeller and the thickened water pump inner container, temperature rise of the engine is low, furthermore, the efficiency of the engine is improved, and the service life of the engine is prolonged.

Description

A kind of outboard machine with cooling package

Technical field

The utility model relates to a kind of outboard machine, and particularly more simple, the cooling effect of a kind of device belongs to the outboard machine technical field better with the outboard machine of cooling package.

Background technique

Outboard machine is mean engine in the hull outside, or directly is soaked in the water, or on the water surface, multiplex in small volume hulls such as yachts, such as the ship of fishing above the rivers, rubber dinghy etc., be common in river, lake fishery City Regions; The motor of outboard machine generally adopts the method for water-cooled to cool off, and namely by feedway near the water the hull is transported to the heat that absorbs motor in the cooling unit on the motor, hot water is discharged again; But the water cooling plant of prior art generally all is the external device on the outboard machine, and manufacture cost is high, and comparatively complicated; And the water yield of water receiving device for cooling transmission is too small in the outboard machine, does not reach good cooling effect.

The model utility content

The utility model purpose be provide in order to overcome the deficiencies in the prior art that a kind of device is more simple, cooling effect is better with the outboard machine of cooling package.

For achieving the above object, the technical solution adopted in the utility model is: a kind of outboard machine with cooling package comprises motor; Described motor comprises cooling package; Described cooling package comprises engine-driving axle, impeller, water pump inner bag, underwater units, water pipe; Described water pump inner bag is arranged in the underwater units; Described water pump inner bag is communicated with outward with underwater units; Be provided with eccentric opening on the described water pump inner bag; Described engine-driving axle passes described eccentric opening; Described impeller is arranged on the engine-driving axle and is positioned at the cavity of water pump inner bag; Be provided with water outlet near on the position of eccentric opening on the described water pump inner bag; The outer radius of described impeller is greater than the center of the eccentric opening ultimate range to the inwall of water pump inner bag, the inner chamber consistency of thickness of the thickness of impeller and water pump inner bag; Described water outlet is connected with an end of water pipe; The other end of described water pipe links to each other with motor.

Preferably, the inner chamber consistency of thickness of the thickness of described impeller and water pump inner bag, and greater than 20 millimeters.

Because the utilization of technique scheme, the utility model compared with prior art has following advantages:

The outboard machine with cooling package of the utility model scheme, comprise the impeller and the water pump inner bag that are connected with the engine-driving axle, the motor that is arranged so that outboard machine is like this worked at the beginning, and the constituent of motor will automatically start and carry out water delivery, and motor is cooled off; The impeller of thickening and water pump inner bag are so that the water flow of this cooling unit is larger, and the temperature rise of motor is lower, and then has improved the efficient of motor, the working life of also having improved motor simultaneously; And the cooling unit production of this outboard machine motor simple and fast that gets up, greatly reduce the cost of production of outboard machine, and improved manufacturing efficiency.

Description of drawings

Below in conjunction with accompanying drawing technical solutions of the utility model are described further:

Accompanying drawing 1 is the sectional view of the cooling package of the motor of the outboard machine with cooling package of the present utility model;

Accompanying drawing 2 is the water pump inner bag of the cooling package of the motor of the outboard machine with cooling package of the present utility model and the plan view of impeller;
