Description

Bunkoeler met maximale zeewater-instromingBin cooler with maximum seawater inflow

De uitvinding heeft betrekking op bunkoelers met horizontale pijpen welke gebruikt worden voor de warmte-afvoer van gesloten koelsystemen aan boord van schepen. Dergelijke koelers bestaan uit een pijpenbundel zonder omhullende mantel, waarbij de pijpen aan beide uiteinden zijn bevestigd in verzamel-kasten, en waarbij het te koelen medium door de pijpen stroomt. In deze verzamelkasten kunnen verdeelschotten worden aangebracht om het te koelen medium meerdere malen door (verschillende delen van) de bundel heen en weer te leiden.The invention relates to horizontal pipe-type box coolers which are used for the heat dissipation of closed cooling systems on board ships. Such coolers consist of a pipe bundle without an enveloping jacket, the pipes being fixed at collectors in both cases, and the medium to be cooled flowing through the pipes. In these collection boxes, dividers can be fitted to guide the medium to be cooled several times through (different parts of) the bundle.

Deze koeler wordt in een zgn. bunkast opgehangen. Deze bun-kast heeft voor een vrije doorstroming met zeewater instroom-openingen in de bodem van het schip, en uitstroom-openingen aan de bovenzijde in de zijkant, juist onder de waterlijn.This cooler is hung in a so-called bunker. This bun cabinet has for free flow with seawater inflow openings in the bottom of the ship, and outflow openings at the top in the side, just below the waterline.

In de bunkast is ten gevolge van de vaarbeweging van het schip, of bij stilliggend schip door de thermische werking van het opwarmende zeewater, een opwaartse stroming van dit koelende zeewater aanwezig.In the bunker there is an upward flow of this cooling seawater as a result of the sailing movement of the ship, or when the ship is stationary due to the thermal effect of the warming seawater.

Bij de gebruikelijke bunkoelers waarin horizontale pijpen worden toegepast treedt alleen langs de onderzijde van het pijpennest water binnen, hetgeen op haar weg naar boven door elke nieuwe pijp die het tegenkomt verder zal worden opgewarmd, en daarmee minder effectief zal worden. Teneinde een tegenstroom-effeet te bereiken zal bij deze koelers, zodra er meerdere pijp-passeringen nodig zijn, altijd sprake zijn van een aanvoerleiding aan de bovenzijde en een afvoerlei-ding aan de onderzijde van de bundel.In the conventional bin coolers in which horizontal pipes are used, water enters only along the underside of the pipe nest, which will be further heated up on its way up through each new pipe it encounters, and thus become less effective. In order to achieve a countercurrent effect, these coolers will always have a supply line at the top and a discharge line at the bottom of the bundle as soon as several pipe passes are required.

De uitvinding bestaat nu hieruit, dat door toepassing van pijpen met een langwerpige doorsnede (d.w.z. rechthoekig met al of niet afgeronde hoeken, ellipsvormig of anderszins langwerpig), waarbij deze pijpen langs de zijden van het pijpennest onder een zodanige hoek verdraaid zijn, dat hierdoor over de volledige hoogte van het pijpennest een instroom van 'vers' zeewater in de pijpenbundel gerealiseerd wordt.The invention now consists in that by using pipes with an elongated cross-section (ie rectangular with rounded or unrounded corners, elliptical or otherwise elongated), these pipes are rotated at such an angle along the sides of the pipe nest that at the full height of the pipe nest, an influx of 'fresh' seawater into the pipe bundle is realized.

Het effect hiervan is in thermisch en konstruktief opzicht posit ie f : le) Doordat ook bovenin de pijpenbundel vers buitenwater binnenstroomt zal het effectief temperatuursverschil (LMTD) groter zijn, hetgeen de capaciteit van de koeler vergroot.The effect of this is positively f: le) From a thermal and constructive point of view: le) Because fresh outside water also flows in at the top of the tube bundle, the effective temperature difference (LMTD) will be greater, which increases the capacity of the cooler.

2e) Konstruktief vervalt de noodzaak van het tegenstroom-effect, zodat bij koelers met meerdere pijp-passerin-gen het te koelen medium d.m.v. de verdeelschotten 'rond' geleid kan worden door het pijpennest, waardoor zowel de inlaat als de uitlaat bovenop de verdeelkasten kunnen worden aangesloten. Dit bespaart veel (meestal beperkt aanwezige) ruimte welke anders nodig is voor de afvoer-leiding.2e) Constructively, the need for the countercurrent effect is eliminated, so that in coolers with multiple pipe passages, the medium to be cooled by means of the dividers can be guided 'round' through the pipe nest, so that both the inlet and the outlet can be connected on top of the distribution boxes. This saves a lot of (usually limited) space which is otherwise required for the discharge pipe.
