Technical Field

The utility model relates to a solar device field, in particular to energy storage type solar water heater thermal-arrest board.

Background

The solar water heater is a heating device for converting solar energy into heat energy, and heats water from low temperature to high temperature so as to meet the requirement of hot water in life and production of people. The heat collector of the water heater is the core part of the water heater, and the solar energy is dispersed, so that the solar energy must be concentrated, the radiant energy of the sun can be converted into heat energy, the solar radiation is absorbed, and the generated heat energy is transferred to the water in the water tank. The heat collector can be flexibly arranged on a roof, a skylight, a balcony or a wall.

The flat plate structure in the solar water heater: the solar heat collector comprises a heat absorbing plate, a cover plate, a heat insulating layer, a shell and the like, belongs to a metal tube plate type structure, can directly or indirectly heat the heat of the heat absorbing plate to heat a circulating water pipe, and has the advantages of low manufacturing cost, large heat collecting area, high heat efficiency, no maintenance, high cost performance and the like. The circulating water pipe of the flat-plate solar water heater has various forms such as a coil pipe type, a flat box type and the like.

Traditional thermal-arrest board is the example, and the apron is glass manufacturing commonly used, has the empty spacer layer of one deck between glass apron and the absorber plate, and the glass apron is isolated hot-air between apron and absorber plate, strengthens the heat absorption effect, and sunshine passes glass and shines on the absorber plate, and the circulating pipe who conducts the heat to the absorber plate lower floor by the absorber plate again to and in the built on stilts air bed of circulating pipe layer, through the indirect heating circulating pipe of heated air, the circulating pipe lower floor sets up thermal-insulated heat preservation. However, the existing flat plate type heat collecting plate has the following defects:

1. the heat storage capacity is limited, the heat collecting plates absorb the heat of solar energy every day and store the heat in the hot water in the water tank, the water amount in the water tank is limited, the requirement of using a large amount of hot water cannot be met, if the heat storage capacity needs to be increased, the volume of the water tank needs to be increased, and the volume of the water tank is limited by the area, the bearing and the like of a house roof.

2. The existing flat plate type heat collecting plate is fragile in structure, due to the fact that an overhead structure between a cover plate and a heat absorbing plate exists and an overhead layer structure of a circulating water pipe layer exists, the whole flat plate type heat collecting plate is made to be just like an eggshell due to the existence of multiple layers of cavities, therefore, the pressure of a heavy object cannot be borne above the heat collecting plate, the heat collecting plate can only be arranged above a roof independently, and the heat collecting plate is easy to damage due to impact of hail or other noons.

We have found some relevant data about the heat collecting plate of the solar water heater with honeycomb structure through patent and literature search, for example:

1. honeycomb solar collector panel, application No.: CN 201510098362.3; the applicant: liu Jun could be obtained; and (3) abstract: a honeycomb solar heat-collecting plate, namely the heat-absorbing coating of box solar cooker and vacuum solar heat pipe water heater can be directly replaced by the soft active carbon honeycomb plate sold in the market, while the solar heat-absorbing plate of the flat plate solar water heater, the high-temperature heat collector at the top of the solar thermal power generation high tower and the heat-absorbing end of the superconducting heat pipe of the waste heat boiler can be replaced by the rigid honeycomb plate containing the heat-absorbing coating.

2. A heat collecting plate having a honeycomb structure; application No.: CN 201621224823.3; the applicant: ningbo wavelength Generator science and technology, Inc.; and (3) abstract: the utility model provides a thermal-arrest board with honeycomb, is fixed by the coincide of double-deck sheet metal and forms together, form the runner between the double-deck sheet metal, the runner is including flowing into the passageway, outflow passageway and honeycomb structure passageway, the honeycomb structure passageway comprises a plurality of hexagon pore structure passageways, and arbitrary two adjacent regular hexagon pore structure passageways communicate each other, the passageway intercommunication of flowing into the regular hexagon pore structure passageway of honeycomb structure passageway one end, the outflow passageway intercommunication the regular hexagon pore structure passageway of the honeycomb structure passageway other end. The utility model discloses the runner structure sets up rationally, has effectively solved the inhomogeneous uneven problem that makes the runner of pressurized in the inflation manufacturing process.

As seen from the above publications, the honeycomb structure used in the existing solar heat collecting panel, as in reference 1, is used on the heat absorbing plate for increasing the heat absorbing area and increasing the heat absorbing efficiency; reference 2 is to arrange the water flow channel in a honeycomb shape to solve the problem of uneven flow channel caused by uneven pressure in the blowing manufacturing process.
