Technical field
The utility model relates to a kind of closed cooling tower, and especially radiator coil tube is a closed cooling tower capillaceous.
Background technology
Cooling tower is a kind of heat power equipment of extensive use, its effect is by heat, matter exchange the heat of high-temperature cooling water to be spilt into atmosphere, thereby reduce the temperature of cooling water, its cold water effect mainly is to mix contact by cold and hot two fluid streams in tower, partly evaporates also by the partial pressure of water vapor official post hot fluid between two fluid streams and self cools off.
Traditional cooling tower generally adopts the open type water cooling, adopt the overbottom pressure of water circulating pump recirculated cooling water to be got on the filler of cooling tower, adopt blower fan through the water cooling of filler then, enter water pond at the bottom of the tower, be extracted in the system of being cooled by water pump then and cool off.The disadvantage of this kind type of cooling is exactly that recirculated water is contaminated easily, cause fouling in pipeline and the cooling system, make cooling effectiveness lower, and clean these dirts and also need the manpower and materials that cost a lot of money, in addition, the filler easy-weathering that this kind mode adopts, equipment uses a period of time will change filler.Therefore be not suitable for various cooling systems that cycle water is had relatively high expectations, as industries such as electric power, chemical industry, iron and steel, food.
In order to address the above problem, prior art adopts closed cooling tower, adopts heat exchanger coils that the air and the medium that is cooled are isolated, and water spray heat exchanger coils is strengthened cooling effect simultaneously.When this closed cooling tower was worked, the medium that is cooled flow through in pipe, and air flows through outside pipe, no longer directly ingress of air of medium is cooled, after water at the bottom of the tower in the cistern is extracted by circulating pump, be sent to that pipe is outer spray equably, by the effect of shower water enhancing heat and mass.Though overcome the shortcoming of traditional cooling tower, because the medium that is cooled no longer directly contacts with air, the heat exchange effect is poor, therefore will further improve the heat exchange effect, the essential heat exchanger coils of improving.
Present its heat exchanger coils of widely used closed cooling tower is made up of copper pipe, in order to obtain heat exchange effect preferably, employing adds the size of large copper pipe, the contact area that promptly increases heat exchanger coils and air and shower water is to reach predetermined heat exchange effect, but strengthen the heat exchanger coils area, just increased simultaneously the space that heat exchanger coils occupies the cooling tower tower body, therefore big to the tower body volume requirement, and do not reach good heat exchange effect.
The utility model content
The utility model provides a kind of closed cooling tower, to improve the heat exchange effect of heat exchanger coils.
In order to achieve the above object, the utility model provides a kind of closed cooling tower, comprise the blower fan that is arranged on cat head, be arranged on water leg, medium inlet and media outlet at the bottom of the tower, be arranged on the heat exchanger coils in the tower, an and spray water division system, wherein, the two ends of described heat exchanger coils are connected with medium inlet and media outlet respectively, described spray water division system is connected to water leg by a water circulating pump, and also be provided with a plurality of nozzles on the spray water division system, wherein said heat exchanger coils is made up of capillary.
Further, described capillary is arranged in the cooling tower in the mode of array module.
Further, described capillary links to each other with media outlet with described medium inlet by water spraying pipe.
Further, described capillary is connected in inner water spraying pipe by the mode of welding.
Further, fill up filler around the described capillary.
Further, described filler is PVC material or film-type heat sink material.
Further, 2 or 2 above filters are used in described medium inlet.
Further, described a plurality of nozzle is positioned at top capillaceous.
The utility model utilizes capillary as heat exchanger coils, capillary network has that heat exchange area is big, the thin thermal conductivity of wall is good, heat exchange is even, therefore can improve the heat exchange effect of cooling tower on the one hand, on the other hand, be equal under the condition of heat exchange, it is littler that the heat exchanger coils of being made up of capillary occupies the cooling tower space, thereby make the volume of cooling tower littler.
