我国当前通常采用内嵌水管通水冷却以降低混凝土温度,但在干旱地区或混凝土结构较高部分采用通水冷却施工较不方便,以空气作为冷却介质进行混凝土冷却能够较好地避免上述问题.相较于通水冷却,通风冷却施工设备较为简单,且由于空气密度较小,可采用竖直方向通风冷却.采用热流耦合单元,充分考虑风、水的沿程温度变化以及冷却管附近混凝土、远离冷却管混凝土不同的温度变化规律,进行通风冷却敏感性分析及通风冷却、通水冷却效果对比.仿真模拟结果表明:通风冷却能够较好地削减混凝土温度峰值;通风风速越快、通风温度越低、混凝土截面越小,通风冷却效果越好;选取适当的风速及通风温度,通风冷却能够达到与通水冷却近似的冷却效果. In our country, water pipe cooling is usually adopted to reduce the temperature of concrete. However, it is not convenient to adopt water cooling in the arid area or the higher part of the concrete structure. Concrete cooling using air as the cooling medium can better avoid the above problems. Compared with the water cooling, ventilation and cooling construction equipment is relatively simple, and because the air density is smaller, the vertical direction can be used for ventilation and cooling.Using the heat flow coupling unit, taking full account of wind and water along the temperature changes and the cooling pipe near the concrete, The results show that: Ventilation cooling can reduce the concrete temperature peak value better; Ventilation air speed is faster, ventilation temperature is higher Low, concrete cross section is smaller, the ventilation cooling effect is better; select the appropriate wind speed and ventilation temperature, ventilation and cooling can achieve the cooling effect similar to the water cooling.
