Abstract

The utility model discloses a cooling device shallow draft launches, automatic pontoon bridges and other ship dynamical systems. The cooling device comprises a gear box cooler, an engine oil cooler in an engine and a built-in fresh water pump of the engine. In the utility model, an outboard cooler and an outboard water pipe are connected between a water inlet of the gear box engine oil cooler and a water outlet of the engine and are respectively installed on the position of a water inlet of a ship propeller and the outer side of a ships; an expansion water tank is arranged on a deck of the ship; a ventilating opening and a water supplying opening of the expansion water tank are respectively connected with the water outlet and a water inlet by the water pipe. The utility model can not generate water break condition and can not damage the engine.

Description

Cooling unit

The utility model relates to a kind of cooling unit of power system.Specifically, be shallow draft motorboat, the power system cooling unit of boats and ships such as bridge of boats voluntarily.

Motorboat, boats and ships such as the bridge of boats voluntarily often need contain the shoal navigation of a large amount of silts, pasture and water and drift.Compound cooling is mostly adopted in the cooling of its power system, promptly utilizes the outboard water pump with in river (lake) the water suction ship, and realizes the cooling of power system circulating water through filter, inboard heat exchanger.Adopt this method, though also can realize the cooling of power system circulating water, but because river (lake) water need pass through outside water intake gate (Sea Chest), outside water water valve (sea cock and valve), water recirculator (inboard heat exchanger), outboard water pump (sea water pump) and outside water filter etc., pasture and water and drift easily stop up the outboard water intake, silt easily is deposited in the filter, thereby cause and cut off the water supply, make motorboat, the engine overheat of boats and ships such as the bridge of boats damages voluntarily.

The purpose of this utility model is to provide a kind of cooling unit, and this cooling unit the situation of cutting off the water supply can not occur, and can not damage motor.

For achieving the above object, the utility model is taked following technical solution:

Cooling unit of the present utility model, comprise the gear-box cooler, the built-in fresh water pump of in-engine machine oil cooler and motor, its structural feature is to be connected to outboard cooler and outboard water pipe between the water outlet of the water intake of gear-box machine oil cooler and motor, and this outboard cooler and outboard water pipe are installed in the water inlet of marine propeller and the outside of boats and ships respectively.Swelling water tank is arranged on the deck of boats and ships, and its ventilation mouth and water supplement port join by the water outlet and the water intake of water pipe and motor respectively.

Because cooler of the present utility model is arranged on the water inlet of marine propeller, and its water intake joins by the water outlet of outboard water pipe and motor, thereby form the enclosed outboard type of cooling, utilize river (lake) water directly power system to be implemented cooling, can not occur cutting off the water supply, engine overheat and situation about damaging at the outboard of boats and ships.Again owing to adopt cooling means of the present utility model, devices such as outside water intake gate (Sea Chest), outside water water valve (sea cock and valve), water recirculator (inboard heat exchanger), outboard water pump (sea water pump) and outside water filter have been saved, not only simplify the structure greatly, also can save manufacture cost.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Fig. 1 is a cooling unit principle schematic of the present utility model;

Fig. 2 is a cooling unit structural representation of the present utility model;

Fig. 3 is the schematic top plan view of Fig. 2.

As shown in Figure 1, cooling unit of the present utility model comprises the built-in fresh water pump 10 of gear-box cooler 12, in-engine machine oil cooler 6 and motor.The water outlet of gear-box machine oil cooler 12 is connected with the water intake of

motor

11, and 5 of the water outlets of its water intake and motor are connected to outboard cooler 1 and outboard water pipe 3.Wherein, outboard cooler 1 is the pipe row formula cooler made from copper tube, is arranged in the water jet propulsion pump water intake 15.5 of the water outlets of the water intake 2 of 13 of the water outlets of the water intake of gear-box machine oil cooler 12 and outboard cooler 1, outboard cooler 1 and the water outlet of outboard water pipe 3 and outboard water pipe 3 and motor all are connected by the side of a ship inner conduit 4 in the cabin 14.One swelling water tank 9 also is installed on the deck of boats and ships, is processed with ventilation mouth 7 and water supplement port 8 on this swelling water tank, ventilation mouth 7 wherein joins by the water outlet 5 of side of a ship inner conduit 4 with motor, and water supplement port 8 links to each other with the water intake 11 of motor by side of a ship inner conduit 4.

As Fig. 2, shown in Figure 3, the present invention is under user mode, and outboard cooler 1 is installed in the water intake 15 of bottom of ship water jet propulsion pump, and outboard water pipe 3 is installed in a side of boats and ships.

This shows, adopt cooling unit of the present invention, do not need in the outside water suction ship, systemic circulation water can be added by swelling water tank 9 with the soft water of cleaning.When engine operation, by in side of a ship inner conduit 4 and the outboard water pipe 6 ascending pipes row formula outboard cooler 1, circulating water in the outboard cooler 1 and river (lake) water carries out heat exchange to its built-in fresh water pump (10), and the temperature of circulating water is reduced with circulating water.The circulating water that has been cooled enters in gear-box machine oil cooler 12 and the motor, thereby gear-box and motor cooled off fully.

Claims

1. cooling unit, the built-in fresh water pump (10) that comprises gear-box cooler (12), in-engine machine oil cooler (6) and motor, it is characterized in that being connected to outboard cooler (1) and outboard water pipe (3) between the water outlet (5) of the water intake of gear-box machine oil cooler (12) and motor, this outboard cooler and outboard water pipe are installed in the water inlet of marine propeller and the outside of boats and ships respectively; Swelling water tank (9) is arranged on the deck of boats and ships, and its ventilation mouth (7) and water supplement port (8) join by the water outlet (5) and the water intake (11) of water pipe and motor respectively.
