An atmospheric pressure loop heat pipe type solar heating device

Abstract

The invention discloses a normal-pressure loop heat pipe type solar heat supply method and device. The device mainly comprises an evaporation system, a condensation system, a sealing system and a water replenishing system. The evaporation system is mainly used for liquid heat absorption vaporization, the condensation system is used for vapor condensation heat supply, and the evaporation system andthe condensation system are connected through a vapor discharging pipe and a liquid backflow pipe to form a loop heat pipe. The device needs no vacuumizing treatment, liquid sealing is formed througha pressure balance pipeline and a water tank, operating is achieved under normal pressure, and non-condensable gas is discharged out during work. According to the device, the loop heat pipe is applied to the solar heat supply device, work is done under the normal pressure, the efficient heat supply efficiency is guaranteed, and the problem about high cost caused by vacuumizing is avoided; and thestructure is simple, design is compact, the device is safe and light, and the method and means for effectively utilizing solar energy are provided.
