Setting up heat exchanger in the diesel engine cooling water tank, utilizing the abundant seawater resource of ship operation on the sea, the great problem of marine diesel fresh water consumption has been solved in the cooling of cooling down of the fresh water used the diesel engine cooling system, it replaces fresh water to get into the easy corrosion of diesel engine inner chamber that the diesel engine cooling system arouses, the technical problem that diesel engine life is short to have solved direct use sea water simultaneously.
Description
Technical field
This utility model belongs to engine-cooling system technical field, and in particular to a kind of cooling of marine diesel engine
System.
Background technology
The effect of diesel engine cooling system be when diesel engine works in good time by the partial heat of strong heated component and
When distribute, it is ensured that diesel engine works under optimum state of temperature.
At present, the ship of operation on the sea typically adopts water-cooled diesel engine as power, when diesel engine works, cooling water
Constantly the cooling to diesel engine is realized in circulation to fresh water in case in diesel engine cooling system, with the prolongation of working time, water
Cooling fresh water temperature in case is constantly raised, or even evaporation.Thus conventional water-cooled diesel engine, it is larger to consume fresh water, when needing
Often supplement fresh water.And the particularity of long-time operation on the sea, the carrying of fresh water and supplement it is relatively difficult；During operation on the sea because sea
Water is taken conveniently, common to have marine diesel directly to replace fresh water to enter diesel engine cooling system enforcement cooling using sea water, but
Its technical problem for existing is, due to the corrosivity of sea water, the easy corrosion of diesel engine cooling system inner chamber, and so as to failure is multiple,
Diesel engine service life is greatly shortened.
The content of the invention
The purpose of this utility model is to provide a kind of cooling system of new suitable marine diesel, solves existing ship and uses
Diesel engine fresh water consumes larger, and replaces the short technical problem of the diesel engine inner chamber easy-to-rust of fresh water, service life with sea water.
To achieve these goals, this utility model is adopted the following technical scheme that：
A kind of marine diesel engine cooling system, including cooling water tank, water saving funnel, heat exchanger, the water saving leakage
Bucket is fixedly installed in cooling water tank top, and the heat exchanger is respectively arranged at two ends with water inlet and outlet, inlet end and goes out
Mouth of a river end is upward through water saving funnel, heat exchanger is located in cooling water tank internal cooling fresh water；The water inlet connection sea
Water water inlet pipe, outlet connection sea water outlet pipe.
Preferably, a sea water tank is also connected between the heat exchanger water inlet and sea water water inlet pipe, it is described
Sea water tank is arranged aboard ship higher than the position of diesel engine radiator.
Preferably, the heat exchanger is made using copper pipe or stainless steel tube.
Operation principle of the present utility model is：Fresh water in diesel engine cooling water tank to diesel engine implement cooling structure and
Principle keeps constant.Heat exchanger is fixedly installed in diesel engine cooling water tank internal cooling fresh water, its water inlet and water outlet
Mouth is connected respectively through water saving funnel with sea water water inlet pipe, sea water outlet pipe.When diesel engine works, by hull outside spiral shell
Rotation paddle blade drives the sea water of room temperature, Jing sea water water inlet pipes to enter heat exchanger, and with the fresh water of heat in cooling water tank heat is carried out
Exchange, realize the cooling down to fresh water in cooling water tank, finally discharge from sea water outlet pipe, flow back to sea.
The beneficial effects of the utility model are：Heat exchanger is set in diesel engine cooling water tank, preferably using ship
The abundant seawater resources of operation on the sea, to the fresh water of diesel engine cooling cooling down is implemented, and makes the fresh water temperature in cooling water tank
Degree will not constantly be raised with the increase of diesel engine working time, even evaporated, so as to reach the effect of fresh-water-saving consumption, solution
Certainly marine diesel fresh water consumes larger problem；Meanwhile, can avoid directly using sea water to replace fresh water to enter diesel engine
Inner chamber cooling system, solves and directly replaces fresh water easily to become rusty into the diesel engine inner chamber that diesel engine cooling system causes using sea water
The short technical problem of erosion, diesel engine service life.

Specific embodiment
Below in conjunction with the accompanying drawings 1-2 is described in detail to this utility model.
Embodiment 1：As shown in figure 1, a kind of marine diesel engine cooling system, is applied to operation on the sea ship, including
Cooling water tank, water saving funnel, heat exchanger, wherein water saving funnel is fixedly installed in cooling water tank top, heat exchanger two ends point
Water inlet and outlet are not provided with, inlet end and water outlet end are upward through water saving funnel, make heat exchanger be relatively fixed position
In cooling water tank internal cooling fresh water；Heat exchanger water inlet connects sea water water inlet pipe, its outlet connection sea water outlet pipe.
When diesel engine works, diesel engine implements the structure and principle of cooling using the fresh water in cooling water tank to diesel engine
Keep constant.Wherein cool down fresh water temperature can be over time prolongation and raise.The present embodiment utilizes hull external helicoid blade
Piece drives the sea water of room temperature, Jing sea water water inlet pipes to enter heat exchanger, with the fresh water in diesel engine cooling water tank heat friendship is carried out
After changing, sea is entered along sea water outlet pipe, take away most of heat of fresh water after heating up in cooling water tank, realized to cold in water tank
But the cooling down of water, makes the fresh water in cooling water tank be unlikely to thermal evaporation.The present invention utilizes sea water pair by heat exchanger
Fresh water in cooling water tank is cooled down, and so as to reach the effect of fresh-water-saving consumption, solves operation on the sea diesel engine peculiar to vessel light
The larger problem of water consumption, directly replaces fresh water to enter diesel engine cooling system while also solving marine diesel using sea water
