Abstract

The utility model provides a solar energy collector which comprises a vacuum heat-preservation shell with a cavity and an inlet and an outlet on the shell. The solar energy collector is characterizedin that a cavity of the vacuum heat-preservation shell is filled with heat-absorbing and energy-storage materials, so that after being delivered into the cavity through an inlet, the fluid to be heated is fast heated by heat exchange with the heat-absorbing and energy-storage materials through various methods of heat transfer by convection, heat radiation and heat conduction, the hot water for production or life is further provided for the users, the hot air for warmth is provided, or the hot air used for production of cured tobaccos, roasted grains and roasted tea is provided. The utility model has the advantages of simple structure, high heat transfer efficiency, wide range of heat utilization and the like, extends the application field of the solar energy, and enables the solar energy to provide more and wider purposes to benefit human beings.

Description

Solar thermal collector

Technical field

The utility model relates to a kind of solar thermal collector, belongs to the solar thermal collector technical field.

Background technology

Fall sharply in resource, in the real society of limited energy, people are when studying and seeking new forms of energy, and also in the utilization of effort research and exploitation solar energy, comparatively successful application simultaneously also worked as the number solar water heater the most widely in the middle of this.The solar water heater of prior art mainly absorbs solar energy by solar vacuum heat-collecting pipe or the board-like heat collector of solar energy, behind the water of continuous heating in it, the hot water of producing or living usefulness is provided to the user, thereby maximally utilise solar energy heating water, save limited electricity, oil and combustion gas equal energy source.But because existing solar thermal collector can only add hot water mostly, and can not heat other heating medium, make the utilization of solar energy be subjected to very big restriction.Therefore, be necessary fully prior art is improved,, allow this inexhaustible heat energy benefit for the mankind to enlarge the range of application of solar energy.

Summary of the invention

The purpose of this utility model is to provide a kind of solar thermal collector, makes it to add hot water, can also add hot-air or other medium, to enlarge the range of application of solar energy, allows solar energy provide efficient heat energy for more wider fields.

The utility model is finished by following technical proposal: a kind of solar thermal collector, comprise the vacuum heat-preserving housing of being with cavity and the import and export on the housing, it is characterized in that in the cavity of vacuum heat-preserving housing, filling heat absorption, energy-accumulation material, so that fluid to be heated is after cavity is sent in import, carry out heat exchange with heat absorption, energy-accumulation material with convection heat transfer' heat-transfer by convection, heat radiation, heat conducting multiple mode, provide high heat fluid such as hot water or hot-air to the user afterwards.

The bottom of described vacuum heat-preserving housing is made as flat board, and the top is made as the arc arch bar, and base platform can conveniently be installed or place, and the arc arch bar helps increasing endotherm area, fully absorbs solar energy.

Be provided with demarcation strip in the described vacuum heat-preserving housing, import and export is established at the two ends of the lattice between the demarcation strip respectively, can improve the intensity of housing first, second helps uniformly transfer heat, to improve heat transfer efficiency.

Described vacuum heat-preserving housing is made as rectangle or polygon or shaped form, so that specifically be provided with as required, to satisfy the demand of user to multiple shape heat collector.

Described vacuum heat-preserving housing is made of double-layer transparent glass and interior vacuum layer thereof, with the convenient solar energy that absorbs, strengthens heat insulation effect simultaneously.

The utility model compared with prior art has following advantage and effect: adopt such scheme, can be by transparent vacuum arc arch bar, make on the direct irradiation of sunlight packing material within it, allow packing material fully absorb heat, accumulation of energy and heating up, make the fluid sent into such as water or air and packing material with convection heat transfer' heat-transfer by convection, heat radiation, heat conducting multiple mode carries out heating up rapidly after the heat exchange, thereby provide the high hot water of producing or living usefulness to the user, the hot-air of heating usefulness perhaps is provided, perhaps flue-cured tobacco, roasting grain, the hot-air of production usefulness such as roasting tea, thereby enlarged the application of solar energy, make solar energy provide more wider purposes for the mankind, to bring benefit to the mankind, the utility model also has simple in structure, heat transfer efficiency height, advantage such as heat utilization is wide.

Description of drawings

Fig. 1 is the concrete application structure schematic diagram of the utility model;

Fig. 2 is the cross-section structure of the utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further, is not limited thereto but hold within the utility model.

The solar thermal collector that the utility model provides, comprise advancing on the vacuum heat-preserving housing 1 of being with cavity 2 and the housing, outlet, in the cavity 2 of vacuum heat-preserving housing 1, fill heat absorption, energy-accumulation material 3 (being sand and rubble), wherein vacuum heat-preserving housing 1 is made as rectangle, constitute by double-layer transparent glass and interior vacuum layer thereof, its bottom is made as dull and stereotyped 6, the top is made as arc arch bar 5, be provided with demarcation strip 4 in the vacuum heat-preserving housing 1, as Fig. 1, the upper end of the lattice 11 between the demarcation strip 4 is established hot water outlet 7 respectively, and each exports 7 and is communicated with hot water house steward 8, hot water house steward 8 is communicated with storage tank 9 tops, the lower end of the lattice 11 between the demarcation strip 4 is established cooling water inlet 12 respectively, and each import 12 is communicated with cold water house steward 10, and cold water house steward 10 is communicated with storage tank 9 bottoms, so that the water in the storage tank 9 are circulated after the heating, provide hot water through hot water outlet 15 to the user, 14 is cooling water inlet, links to each other with the tap water supply pipe, to replenish cold water, as Fig. 2 to storage tank 9.
