Abstract

The utility model relates to a waveform vacuum plate (2) which is made of solar thermal connection and reflection glass, can improve the working state of the heat-collection cylinder of vacuum-plate solar water heaters, and improve the heat availability. The utility model is an arc-glass waveform plate. A full-spectrum conduction heat absorption layer is coated on the inner arc surface; a specular layer is closely covered on the opening of the case (1) of the heat-collection cylinder; the collected heat energy converted from the sunshine is reflected to an endothermic pipe group (3) at the focal point to heat; the sunshine need not penetrate through the double glass layer of the glass vacuum plate, and the arc structure need not be added with a cervical rib. Since the arc specular focusing effect makes the surface heating temperature of the endothermic pipe group (3) higher than the temperature of the heat absorption layer of the arc plate, the waveform face drops the temperature in the space inside the case, achieving the purpose of optimizing the working state of the heat-collection cylinder and improving the heat availability. The utility model can be used to design novel roof energy parts and widen the application of solar thermal engineering.

Description

Sunlight thermal-arrest reflecting glass wave-type vacuum plate

The utility model relates to a kind ofly can be converted to sunlight heat energy and reflexing to of assembling heated on the endothermic tube group and the sunlight thermal-arrest reflecting glass wave-type vacuum plate heat insulation with the external world.

At present, the glass vacuum tube chain of known " solar vacuum-tube water heater " is equipped and is located on the plane skylight face and can not accepts sunlight by gross area, and the heat absorption reflecting surface of inner tubal wall directly adds hot water and causes the scale deposition dirt, makes the forfeiture of thermal conductivity decline minute surface reflection effect; Patent evacuated panel sunlight water heater (patent No.: glass vacuum plate 99241823.2), only rise in the printing opacity heat-blocking action sheet separation and must establish ribbed stiffener, sunlight just can be converted to heat energy after seeing through double glazing, thereby influence heat is imitated.

The purpose of this utility model provides a kind of sunlight thermal-arrest reflecting glass wave-type vacuum plate, and it all very leads sunlight behind the plate face by daylighting area and the vacuum gap and is converted to the endothermic tube group that heating that heat energy assembled by the minute surface reflection simultaneously is arranged on this arc focus place on the heat absorbing coating in the full spectrum of internal layer arc face.Its arch structure must not established ribbed stiffener again, thereby makes the glass vacuum plate and the sunlight heat absorption reflecting plate (patent No.: 01260629.4) unite two into one, avoided the deficiency and the drawback of above-mentioned present situation.

The purpose of this utility model is achieved in that and replaces intrinsic glass vacuum plate tightly to be covered on the case mouth on evacuated panel sunlight water heater heat-collecting box, very lead in the full spectrum of internal layer cambered surface through outer globoidal glass and vacuum gap when sunlight and to be converted to heat energy on the heat absorbing coating and to heat through reflexing on the endothermic tube group that is arranged on this focus place of assembling of arc minute surface simultaneously, replaced the former sunlight heat absorption reflecting plate that is arranged under the glass vacuum plate, still formed an airtight minute surface reflection space with the minute surface reflected bottom plate.Sunlight thermal-arrest reflecting glass wave-type vacuum plate is the new parts that glass vacuum plate and sunlight heat absorption reflecting plate unites two into one, and it does not sincerely make the configured in one piece of evacuated panel sunlight water heater and structure be improved and optimizes and also improved hot effect; Can design new type roof energy parts as prototype, the application of sunlight heat enginnering is expanded.

Below in conjunction with drawings and Examples the utility model is described further.

Fig. 1 is the install figure of the utility model at evacuated panel sunlight water heater heat-collecting box mouth.

Fig. 2 is the I-I cutaway view of Fig. 1.

Fig. 3 is the structure chart of sunlight thermal-arrest reflecting glass wave-type vacuum plate.

Among the figure 1, heat-collecting box shell 2, sunlight thermal-arrest reflecting glass wave-type vacuum plate 3, endothermic tube group 4, cycle heat exchange water pipe 5, minute surface reflected bottom plate.

In Fig. 1, heat-collecting box shell (1), sunlight thermal-arrest reflecting glass wave-type vacuum plate (2), endothermic tube group (3), cycle heat exchange water pipe (4), minute surface reflected bottom plate (5) are formed the heat-collecting box of evacuated panel sunlight water heater.

In the embodiment shown in fig. 1, the case mouth that is sealed on heat-collecting box that sunlight thermal-arrest reflecting glass wave-type vacuum plate (2) is tight is also formed the minute surface reflection space of a heat-insulating and sealing jointly with minute surface reflected bottom plate (5), medium in the heating endothermic tube group (3) that the heat energy that sunlight is converted to is assembled, the medium that obtains heat carries out heat exchange heating water wherein with cycle heat exchange pipe (4) again, thereafter, the water that is heated is circulated to heat preservation storage water tank (reservoir, boiled water tank) by thermodynamic principles and finishes the work that evacuated panel sunlight water heater is produced hot water and boiling water.

In the embodiment shown in fig. 3; Sunlight thermal-arrest reflecting glass wave-type vacuum plate (2) is to make with high-quality glass blow pressure, and the thickness of inside and outside corrugated sheet face is 1.5～3 millimeters, 5～8 millimeters of plate intermediate gaps, vacuum 0.05Pa.Outer corrugated glass plate and vacuum gap play the printing opacity heat-blocking action; Internal layer spraying full-spectrum good-conductive heat absorption layer plates specular layer again, and the endothermic tube group (3) that reflexes to that the heat energy that plays that sunlight is converted to is also assembled goes up heating.Its global shape is a waveform arch cored slab structure, mechanical property is good, practical make glass vacuum plate and sunlight heat absorption reflecting plate unite two into one, thereby structure, the raising heat of having optimized whole heat-collecting box are imitated and duty, can design new type roof energy parts as original shape, make the sunlight heat enginnering be equipped with New Terms to the indoor heating wound.

Claims

A kind of thermal-arrest reflecting glass wave-type vacuum plate, it is to be thermal source with sunlight, with transform light energy is the parts of assembling again behind the heat energy that heat on the heat sink that reflex to, it is characterized in that: on the internal layer cambered plate that connects the arc glass evacuated panel, be coated with full-spectrum good-conductive heat absorption layer and specular layer, outer arc glass plate face and vacuum gap play the printing opacity heat-blocking action, be used on the evacuated panel sunlight water heater heat-collecting box tight capping case mouth and form the minute surface space of sealing jointly with the minute surface reflected bottom plate on the thermal insulation layer at the bottom of the heat-collecting box, by the principle heating endothermic tube group of mirrored effect, can expand novel sunlight heat enginnering as original shape.
