Focused 45-degree angle special-shaped heat preservation medium tank under parabolic reflector

Abstract

The invention discloses a focused 45-degree angle special-shaped heat preservation medium tank under a parabolic reflector, and belongs to the field of manufacture of high-temperature utilization equipment in solar energy. The heat preservation medium tank mainly solves the problem that the rotation of a parabolic reflecting surface is blocked by the heat preservation tank when the heat preservation is relatively immobile. The invention has the innovation that: the heat preservation tank is changed into a special-shaped heat preservation medium tank, namely the vertical sections of an inner container and the skin of the heat preservation medium tank are of 45-degree angle trapezoid, the special-shaped heat preservation medium tank or only the upper part of the heat preservation medium tank is of a round table, and the bus of the round table and the bottom surface form a 45-degree angle. The angle can ensure that the parabolic reflecting surface rotates for 45 degrees front and back, left and right by using a central symmetrical line as the axis and can rotate in a range of east-west or south-north 90 degrees. The heat preservation tank can move at an angle according to the gears, namely the heat preservation tank can move at one angle in the morning and at the other angle in the afternoon so as to ensure that the parabolic reflecting surface receives sunlight in a range of east-west 180 degrees. The upper bottom of the round table is made into an opening serving as a light through hole, and the lower bottom of the round table or the lower edge of the heat preservation tankis made into an absorption surface for absorbing the sunlight.

Description

[0001] Technical field: medium and high temperature solar energy Background technique: [0002] Molten salt phase change materials for medium and high temperature utilization of solar energy have been widely studied and applied in some fields, but small-scale phase change energy storage technology suitable for ordinary people has not been effectively developed. Invention content: [0003] At present, the medium and high temperature technology of solar energy generally concentrates light to generate high temperature to melt salts to promote phase change. The medium and high temperature phase change solar energy of the parabolic reflector downward focusing type adopts the change of the "upper focusing" of the solar cooker to the "lower focusing", which can solve the problem. It has the characteristics of storing phase change energy, not blocking sunlight, reducing exercise load, and facilitating engineering connection. However, if the incubator below does not move, it will aff...
