Abstract

Disclosed is a natural water cooler. End caps provided with inlet and outlet are oppositely arranged on left and right, and are connected with a grid plate densely distributed with a plurality of holes. A plurality of water pipes are welded on the grid plate to form water pipe bundles which are parallel to each other with a certain space, and the water pipes are communicated with the inner cavity of the end caps via the grid plate to form a freshwater single-pass, or double-pass, or three-pass circulation pipeline according to a flange position and the arrangement of a baffle plate arranged in the inner cavity of the end caps. A cooler is arranged on a ship bottom plate, and sea water enters the gap of the water pipe bundles to flow alternatively through a multi-hole guard plate fixed on the end caps. The utility model cools freshwater by the flow rate of sea water or the propelling water speed of a screw propeller, which solves the problem that original freshwater coolers have poor radiation effect, enhances the power of a diesel machine, reduces oil consumption and prolongs service life.

Description

Natural water cooler

The utility model relates to the heat exchange rig of diesel engine for boats.

Hydrocooler is the requisite annex of diesel engine for boats, and it is contained in the front upper place of diesel engine.The shell-and-tube hydrocooler of traditional diesel engine for boats, fresh water closed-cycle system device and seawater open-cycle system device need be set in the cabin, complex structure but also be to rely on sea water pump that seawater is pumped into the cooling vessel hydroecium to enter water pipe not only, take away the fresh water heat through several flow processs and flow into the sea, thereby reach the interior fresh water purpose of cooling fresh-water tank.Because the easy contamination dirt of connecting the sea water in the conventional cooler water pipe, and it is blocked, water pipe is outer because the plate baffle effect, cause water speed uneven, make water speed locate easy contamination dirt slowly, the cooling vessel heating area reduces gradually, radiating effect is poor, cause the fresh water in the fresh-water tank not cool off and often reach boiling and evaporating state,, after working in 1-2 hour, will in fresh-water tank, add fresh water in order to solve this contradiction, but the fisherman is busy with fishing, day and night operation can't be accomplished this point, therefore, in the domestic coastal, small fishing vessel is generally removed cooling vessel, and utilize the seawater direct quenching, because diesel engine requires about 60 ℃ of inflow temperatures, and seawater inflow temperature in winter has only 2-5 ℃, also have only summer about 30 ℃, make engine long be in running under the cold friction duty period, cause diesel engine power to descend consumption increase, kinematic pair weares and teares too early, the dirty again perishable metal of seawater makes the diesel engine lost of life, and cylinder head breaks even.Therefore, how to change cycle mode give full play to cooling vessel should have the effect existing structure cooling vessel be to be beyond one's reach.

The purpose of this utility model provides a kind of untreated water cooling vessel simple in structure that cools off fresh water in the seawater, by seawater that is immersed at the deficiencies in the prior art, improve heat transfer capability, solve the fresh water cooling problem of diesel engine for boats, overcome disadvantages such as diesel engine power decline that direct cooled with seawater brings, consumption increase, the lost of life.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the A-A cutaway view of Fig. 1.

Fig. 3 is the B-B cutaway view of Fig. 1.

Followingly be described in detail according to above-mentioned accompanying drawing embodiment.

The design of the utility model untreated water cooling vessel is based on cooling vessel is immersed in the seawater, allow nature seawater in the channelling of festoon outer wall, the fresh water that has heat that the diesel engine for boats that advances water speed to cool off to flow through 1～3 flow process in festoon by seawater velocity or propeller is discharged reaches cooling performance.

Untreated water cooling vessel (referring to Fig. 1-3) has two split type housings part in addition, it is fixedly connected on the ship outer casing base plate, be about the end cap 2 of configuration relatively, have on the end cap 2 to connect the flange 1 that the diesel engine freshwater source advances (or going out) mouth, fresh water enters end cap 2 inner chambers thus or discharges thus.Be that corrosion resistant copper is the many water pipes 11 of raw material between the left and right sides end cap 2, with brazing or soldering on the densely covered pory left and right sides screen 6 that copper material is made, form parallel to each other and have the festoon in certain distance gap, how many water pipes 11 is decided on diesel engine power, as 150 horsepowers diesel engines just with 107 water pipes.Water pipe 11 endoporus are 16 millimeters of φ 5～φ, communicate and connect with end cap 2 inner chambers with through hole on the left and right sides screen 6, and the aperture of screen 6 is slightly larger than water pipe 11 internal diameters.Left and right sides screen 6 again with about the end cap 2 of relative configuration be fixedly connected, the pad 5 that leakproof seal is used is equipped with in its junction, pad 5 is made with varnished pressboard or sheepskin.The bottom of end cap 2 is being fixed has the pory backplate 4 that gathers, and just eyelet and another side enter in the gap of festoon and fresh water in pipe outer wall channelling cooling pipe seawater thus.

The profile of end cap 2 is a principle to reduce the seawater resistance as far as possible conveniently to the influence and the coastal works of ship's speed, is designed to half moon or semicircle or two disc mid-plane or trapezoidal.

The light hot water that diesel engine for boats is discharged enters fresh-water tank after the cooling vessel cooling, cooling vessel and fresh-water tank branch are arranged and are convenient to management, cancellation seawater open-cycle system.The fresh water flow process can be one way or round trip or three journeys in the festoon.Be configured in 2, one of the end caps in left side when being configured in right side end cap 2 when connecting 1 one of flanges that freshwater source enters (or going out) mouthful, form the fresh water one-way stream and thread a pipe.

When connecting flange 1 centralized configuration that freshwater source enters (or going out) mouthful at left side end cap 2 or right side end cap 2, at this moment left side or right side end cap 2 inner chambers should have a disjunctor dividing plate 8 that end cap 2 inner chambers are divided into two hydroeciums mutually, promptly form fresh water round trip circulation duct.

1 one of flanges that advance (or going out) mouth when the connection freshwater source are configured in left side end cap 2, one is configured in right side end cap 2, and end cap 2 inner chambers in the left and right sides all have dividing plate 8 to be separated by, constitute hydroecium I 3 and hydroecium II 10, hydroecium III 7 and hydroecium IV 9, promptly form fresh water three journey circulation ducts, present embodiment is three journey circulation ducts.

Diesel coolant with heat enters end cap 2 inner chamber hydroecium I 3 → festoon → hydroecium III 7 → festoon → hydroecium II 10 → festoon → hydroecium IV 9 by flange 1 import, enter fresh-water tank by flange 1 outlet through coolant outlet pipe again, the fresh water that process 3 flow processs like this flow has fully been cooled off by the outer seawater of festoon has taken away heat, makes the cooling water expansion tank of diesel engine remain on about 60 ℃ of inflow temperatures.

Natural water cooler according to the utility model design, cancel original seawater open-cycle system, eliminated the trouble and worry that therefore system reason produces, cooler separates with fresh-water tank, fresh-water tank suitably amplified and be positioned over the outer appropriate location of bridge, be convenient to management, in addition, the wind-force that ship's speed is produced helps further to its cooling, this cooler is arranged on ship outer casing and is immersed in the seawater, advance water speed to come the interior fresh water of cooling water tube bank by seawater velocity or propeller, thoroughly solved the problem of the former fresh-water cooler weak heat-dissipating of marine diesel, guarantee that the diesel engine inflow temperature about 60 ℃, improves power to diesel engine, life-saving has a positive effect. This is simple in structure, enforcement is easy, is worthy of popularization.
