The invention discloses a medium automatic compensation pipeline, the main pipeline is a closed pipeline of a series circulating pump, through a branch pipeline, a liquid storage tank is connected in parallel at the inlet and outlet ends of the circulating pump, and the branch pipeline at the outlet end is provided with a closed valve. The solar heat conduction pipeline is composed of the main pipeline of the medium automatic compensation pipeline, the solar collector plate and the water tank in series in the main pipeline, and the heat transfer medium in the main pipeline transmits heat energy. The closed main pipeline is replaced by the open one, and the circulating pipeline is in the state of micro-pressure when it is running, so that the heat transfer medium in the main pipeline is always in the state of filling; the loss of heat transfer medium can also be pumped back by the circulating pump; the defects of pressure balance in the pipe and the difficulty of heat transfer medium compensation are solved; compared with the existing technology, the top exhaust valve, expansion tank and pressure valve are removed. It greatly reduces the failure rate of operation and maintenance cost, improves the efficiency of solar energy collection, and has strong practicability and wide applicability.

一种介质自动补偿管路及太阳能导热管路
本专利技术涉及一种自动补偿管路,具体涉及一种介质自动补偿管路及太阳能导热管路。
技术介绍
现有的平板承压式太阳能传热介质(防冻液)导热循环管路,其管路压力是变化的,随着温度的升高而增大;因此,现阶段大部分厂家采用压力膨胀罐、顶端排气阀、管道压力阀等组件,来调节因循环管路导热介质(防冻液)温度变化造成的管路压力变化。且,同时存在传热介质(防冻液)易损耗缺陷,例如:①、温度升高时,管路压力增大,各接口处易泄露传热介质(防冻液)。②、顶端排气阀工作时传热介质(防冻液)易少量排除出。传热介质(防冻液)损耗后,膨胀罐能有少量补偿,当膨胀罐压力释放后就补偿不了。循环管路因缺少传热介质(防冻液)而出现空泡,会导致循坏系统工作异常,甚至不工作,大大降低导热效果,造成太阳能集热效率降低。正常状态下,太阳能安装在楼顶,经常维护极为不方便,间接增加了使用成本。
