Phase-change energy pile based on flexible phase-change material and preparation method of phase-change energy pile
The invention discloses a phase-change energy pile based on a flexible phase-change material, which comprises a cylindrical structure reinforcement cage defined by a plurality of longitudinal main reinforcements and transverse stirrups, a spiral structure support rod is welded in the middle position from bottom to top, and the tubular flexible phase-change material is spirally wound on the spiral structure support rod; the tubular flexible phase-change material comprises a flexible phase-change material, a heat exchange tube and a metal hoop, the outer end of the heat exchange tube is sleeved with the flexible phase-change material in a segmented mode, and the connector of the two segments of the flexible phase-change material is fixed through the metal hoop; one end of each heat exchange pipe is a water inlet, the other end of each heat exchange pipe is a water outlet, the heat exchange pipes are fixed to the same transverse stirrup, and other gaps in the pile body are filled with concrete. The flexible phase change material is formed by mixing paraffin, white oil and an olefin block copolymer through a melt blending method. The energy storage performance of the pile body can be obviously improved, the strength of the pile body is prevented from being reduced while the heat exchange efficiency of the pile body is improved, a series of problems caused by temperature fluctuation of the pile body are reduced, and the application field is wide.
本发明公开了一种基于柔性相变材料的相变能源桩，包括由若干根纵向主筋和横向箍筋围成的筒状结构钢筋笼，从下到上中间位置焊接有螺旋结构支撑杆，螺旋结构支撑杆上螺旋缠绕有管状柔性相变材料；管状柔性相变材料包括柔性相变材料、换热管和金属卡箍，换热管外端分段套设有柔性相变材料，两段柔性相变材料的接口处通过金属卡箍固定；换热管一端为进水口、另一端为出水口，固定在同一根横向箍筋上，混凝土填充桩体内部其它缝隙；柔性相变材料由石蜡、白油和烯烃嵌段共聚物通过熔融共混法混合而成。本发明可以明显提升桩体储能性能，在提升桩体换热效率的同时避免了桩身强度下降，减少了桩体因温度波动产生的一系列问题，应用领域广阔。
