Thermoelectric integrated device with solar vacuum tubes

Abstract

The invention relates to a heat utilizing device with vacuum tubes, and discloses a thermoelectric integrated device with solar vacuum tubes, which comprises a water tank, at least two vacuum tubes and heat tubes. The quantity of the heat tubes is identical to that of the vacuum tubes; a support with an n-shaped section is arranged in each vacuum tube along the length direction of the vacuum tube, each support is provided with a horizontal plate and two vertical plates, each horizontal plate is positioned at a sectional chord of the corresponding vacuum tube, the upper end of each vertical plate is connected with the corresponding horizontal plate while the lower end of the vertical plate contacts with the inner wall of the corresponding vacuum tube, the horizontal plates are heat absorbing plates, silicon cells are laid on upper surfaces of the horizontal plates and are serially connected according to required voltage, leads of the silicon cells extend out of openings of the vacuum tubes, a suspension hollow bracket is arranged on the lower surface of each horizontal plate and positioned between the corresponding two vertical plates at intervals, and the heat tubes penetrate through the hollow brackets; the openings of the vacuum tubes are sealed by sealing plugs, and exposed heat discharge ends of the heat tubes are inserted into the water tank; and bottoms of each two adjacent vacuum tubes are connected by a reflector. By the aid of the thermoelectric integrated device, solar energy can be simultaneously converted into electric energy and heat energy, thermoelectric conversion efficiency of the solar energy is improved, loss due to the fact that electricity and heat are generated after light rays penetrate through glass and are focused is reduced, and the thermoelectric integrated device is high-efficiency and is low in cost.

Description

technical field [0001] The invention relates to a vacuum tube heat utilization device, in particular to a solar vacuum tube thermoelectric integration device. Background technique [0002] Most of the existing solar vacuum tubes are used in water heaters. Sunlight shines on the outer wall of the vacuum tube, and the heat is absorbed by the inner heat-absorbing coating through the vacuum tube wall, thereby heating the water, and the hot water and the cold water in the water tank circulate alternately; A heat pipe is placed inside, and the inner wall of the pipe is coated with an absorbing coating to absorb heat. The heat is transferred to the water tank through the heat pipe to heat the water. Increase heat, but this method wastes too much space and blocks part of the sunlight; there are also vacuum tubes that use concentrated light to generate electricity; however, the existing vacuum tube heat utilization devices have certain shortcomings and cannot fully utilize solar ener...

[0002] Most of the existing solar vacuum tubes are used in water heaters. Sunlight shines on the outer wall of the vacuum tube, and the heat is absorbed by the inner heat-absorbing coating through the vacuum tube wall, thereby heating the water, and the hot water and the cold water in the water tank circulate alternately; A heat pipe is placed inside, and the inner wall of the pipe is coated with an absorbing coating to absorb heat. The heat is transferred to the water tank through the heat pipe to heat the water. Increase heat, but this method wastes too much space and blocks part of the sunlight; there are also vacuum tubes that use concentrated light to generate electricity; however, the existing vacuum tube heat utilization devices have certain shortcomings and cannot fully utilize solar energy, regardless of concentrated light generation or heat generation, are relatively simple, and the light has to pass through the glass several times, the loss is relatively large, and the heat utilization and power generation efficiency is not high
