The interior temperature of the massive concrete should be controlled to avoid cracks caused by the trapped hydration heat. In this paper, an enhanced heat transfer pipe array with spiral fins (PSF) is proposed to reduce the interior temperature of concrete blocks. Numerical simulations of massive concrete blocks embedded with traditional cooling water pipe (TCWP) and newly proposed PSF were conducted to investigate the interior temperature distribution of massive concrete. Meanwhile, validity of the finite element model was verified by both theoretical results and available experimental data. Based on the calculated temperature distribution of the points located in the interior area of the massive concrete, it is shown that when the TCWP was replaced by the PSF, the interior temperature can be significantly reduced. Therefore, compared to the TCWP, the proposed PSF has excellent heat transfer performance for cooling the interior temperature of massive concrete.

大块混凝土的内部温度应加以控制，以免因水化热的夹带而产生裂缝。本文提出了一种增强的带有螺旋肋片的传热管阵列（PSF），以降低混凝土砌块的内部温度。为了研究大体积混凝土的内部温度分布，对采用传统冷却水管（TCWP）和新提出的PSF的大体积混凝土砌块进行了数值模拟。同时，通过理论结果和现有实验数据验证了有限元模型的有效性。根据计算得出的位于大体积混凝土内部区域的点的温度分布，可以看出，当用PSF代替TCWP时，可以显着降低内部温度。因此，
