Description

一种用于冷却塔的散热装置 A cooling device for cooling towers

技术领域 technical field

本实用新型涉及一种用于冷却塔的散热装置,特别适用于安装在冷却塔的洒水盘内进行散热的装置。The utility model relates to a heat dissipation device for a cooling tower, and is particularly suitable for being installed in a sprinkler tray of a cooling tower for heat dissipation.

背景技术 Background technique

传统冷却塔的洒水盘内没有任何散热装置,空调机排出的热水经管道通入冷却塔的洒水盘中,然后由洒水盘分布落入填料片层中进行冷却散热。在此过程中,热水在洒水盘中基本没有任何散热的机会,因此直接落入填料片层的热水温度较高,致使冷却塔的散热效能无法进一步提高。There is no heat dissipation device in the sprinkler pan of the traditional cooling tower. The hot water discharged from the air conditioner is passed through the pipeline into the sprinkler pan of the cooling tower, and then distributed by the sprinkler pan and falls into the packing sheet layer for cooling and heat dissipation. During this process, the hot water basically does not have any opportunity to dissipate heat in the sprinkler pan, so the temperature of the hot water directly falling into the packing layer is relatively high, so that the heat dissipation efficiency of the cooling tower cannot be further improved.
