DOUBLE VACUUM TUBE TYPE SOLAR HEAT COLLECTOR

摘要

PURPOSE: A solar heat collection apparatus with dual vacuum pipes is provided to prevent damage to the dual vacuum pipes as an inflow pipe and a discharge pipe are connected by a diagonal connecting pipe. CONSTITUTION: A solar heat collection apparatus with dual vacuum pipes comprises an inflow pipe(1), a discharge pipe(2), and a plurality of heat medium pipes(10). The first and second circulation pipes of the heat medium pipes are integrally connected to a connection pipe. One side of the heat medium pipes is connected to the inflow pipe, and the other side is connected to the discharge pipe. The first and second circulation pipes are inserted into the dual vacuum pipe. The inflow pipe and discharge pipe comprise a curved portion on each side. One upper side of the heat medium pipe is connected to the inflow pipe by a first diagonal connecting pipe. The other upper side of the heat medium pipe is connected to the discharge pipe by a second diagonal connecting pipe.
