Description
Technical field
The present invention is relevant with cooling tower, more specifically refers to a kind of heat-dissipating structure of cooling tower.
Background technology
Cooling tower general at present is mainly generally divided into two kinds, one is open, another kind is then closed, wherein open cooling tower is directly cooled by fin and fan, via pump, cooling water and thermal source are done cold and hot exchange, and spatter loss during the heat radiation of open type cooling water tower, dust in air, dirty gas and cooling water mix, cooling water enrichment accelerated accumulation (being about 20 ~ 30 times of former water source), make the cooling water of highly enriched degree when exchange cold and hot with thermal source, incrustation scale (calcium carbonate) can be produced, this is the puzzlement using cooling tower, incrustation scale (calcium carbonate) not only affects the cold and hot exchange of thermal source, more can affect the running of machine, make inefficiency, expend the energy, easy disorderly closedown, and then impact is produced.But, incrustation scale (calcium carbonate) be removed, acid must be used, basic agent decomposes, but the copper pipe easily injured on the contrary in cooling system and system materials and parts, cause entire machine to be scrapped, therefore incrustation scale is puzzlement common in open cooling system.
Another kind of closed-type water cooling tower is then exchanged by the cold and hot metal of many one decks; namely secondary cooling water cools indirectly, does not have the concentrated cooling water of accumulation and thermal source to do cold and hot exchange, so there is no the puzzlement of incrustation scale in pipe; also need not the risk of useful pickling, more do not shut down and fault because disturbing.But, in the streets all closed-type water cooling towers are all square design at present, the making of cooling twice metal pipe coil elbow used, welding, main is very complicated, although closed adopts many one decks indirectly to cool, the puzzlement of open type cooling water tower incrustation scale can be overcome completely, but in the streets selling price is after 10 times of general style of opening, causes buyer to step back because of price.
