Abstract
The utility model relates to a solar-energy heat collector of drum type, comprising a bracket, a heat collecting drum with two ends coated with installation material. The heat collecting drum is a ring-shaped cavity formed by a transparent outer drum and an inner drum with a selective coating; the two drums are concentric; the space between the inner drum and the outer drum is separated at least two cavities by a oblong transparent plate; the insulation layer on the two ends of the heat collecting drum are separately fixed with two bearings, the inner holes of which is fixed with two heat exchanging pipes of a welding support; one end of the insulation layer are fixed with a large gear and is concentric with the heat collection drum; the large gear meshes with a small gear of a motor fixed on the support and drives the heat collecting drum to rotate; the air in the cavity formed by the outer and the inner heat collecting drum and the transparent plate also rotates; under the radiation of sunshine, the surface temperature of the inner heat collecting drum is higher than that of the outer heat collecting drum; the air rotates with the heat collecting drums synchronously; when the rotary angular velocity keeps unchanging, air convection can be reduced, thus effectively decreasing heat loss of air convection, so as to improve heat utilization efficiency.
Description
Technical field
The utility model relates to a kind of cylinder solar thermal collector.
Background technology
Existing flat-plate solar collector heat insulation effect is poor, and heat utilization efficiency is low.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes flat-plate solar collector, and a kind of cylinder solar thermal collector is provided.
The cylinder solar thermal collector, comprise support, having two ends is heat collecting cylinders of heat-insulation layer, heat collecting cylinder is concentric drums by transparent urceolus with the inner core with selection coating, the looping cavity, be divided at least two cavitys by at least one rectangle transparent panel between inner core and the urceolus, the heat-insulation layer at heat collecting cylinder two ends is affixed two bearings respectively, the endoporus of bearing respectively with welding support on two heat exchanger tubes affixed, the affixed gear wheel of heat-insulation layer one end is also concentric with heat collecting cylinder, gear wheel and the pinion that is fixed in the motor on the support.
Cylinder solar thermal collector horizontal positioned, pinion gear wheel drive heat collecting cylinder rotation when motor, gas rotation in the cavity that heat collecting cylinder urceolus inner core and transparent panel constitute, sunlight is through the surface of urceolus irradiation heat collecting cylinder inner core, the inner core temperature is higher than urceolus, gas is synchronized with the heat collecting cylinder rotation, and rotate perpendicular to horizontal direction, when angular velocity of rotation one timing, gas is subjected to the effect of centrifugal force and gravity simultaneously, the centrifugal force of gas place radius is during greater than gravity, the convection current of gas will be reduced, thereby effectively reduced the convection heat losses of heat collector,, thereby improved heat utilization efficiency because the absorber of heat collecting cylinder scribbles the radiation heat loss who selects coating to reduce heat collector.
