Description
Technical field:
The present invention relates to the solar energy utilization technique field, specifically is a kind of solar energy heat collector.
Background technology:
Solar energy heat collector commonly used now generally is made up of glass heat-collecting vacuum tube.This glass heat-collecting vacuum tube is to be formed by connecting at common open end by inside and outside two glass blind pipes, and forms vacuum chamber between two pipes, at interior glass blind pipe outer surface heat-sink shell is set, and gives heat transferring medium in the interior glass blind pipe with the thermal energy transfer that absorbs.This thermal-collecting tube technology difficulty in manufacture process is big, cost is high, easily be damaged in transportation, the installation process, owing to inner and outer pipes temperature difference, inner and outer pipes is damaged easily because of long-term expanded by heating degree is different, the replacement cost height after the damage, replacing difficulty are big in the use.During use inner glass tube is directly and heat transferring medium---and as water, contact, because glass tube can not pressure-bearing, so the water yield of passing through in the pipe is few, thereby in the unit light-receiving area, photo-thermal conversion efficiency is low, and heat time heating time is long.
Summary of the invention:
The object of the invention is to provide that a kind of manufacturing is simple, cost is low, and transportation, simple installation are easy to safeguard, and the solar energy heat collector of thermal conversion rate preferably can be provided.
The technical solution adopted for the present invention to solve the technical problems is as follows:
A kind of solar energy heat collector comprises heat-sink shell 3 that is located at this device middle part and the heat exchange container that is contained in its underpart, and heat transferring medium is housed in heat exchange container.Its top also is provided with a stay-warm case, and this stay-warm case is made up of the glass tube of arranging side by side more than at least three or three, links to each other side by side between the glass tube.
The inside of described glass tube is vacuum.
The cross section of described glass tube is circular.
The described glass tube that links to each other side by side is arranged in planar shaped or curved surface shaped and matches with the top of heat exchange container.
Described heat-sink shell is made up of the heat-absorbing material that is coated in the heat exchange container outer surface of upper, and heat exchange container touches near the bottom of stay-warm case or with the bottom connection of stay-warm case.
Described heat-sink shell is made up of the heat-absorbing material that is coated in the stay-warm case bottom outer surface, and heat exchange container top becomes an opening, and stay-warm case covers on the opening of heat exchange container, and heat-sink shell contacts with heat transferring medium.
Described heat-sink shell is made up of the heat-absorbing material that is coated in the glass tube bottom interior surface, and heat exchange container top becomes an opening, and stay-warm case covers on the opening of heat exchange container, and the bottom of stay-warm case contacts with heat transferring medium.
Stay-warm case among the present invention is the mono-layer tube structure, so be easy to actual production, processing and transportation, compares more durable, not fragile with the heat collector of traditional double-layer sleeve structure.Because heat transferring medium needn't pass through from glass tube, thereby does not have the pressure-bearing problem.Because heat-sink shell can directly contact with heat transferring medium shell or heat transferring medium, so the thermal conversion rate height, Jia Re area is big simultaneously, firing rate is fast simultaneously.The installation of stay-warm case is very easy, both can many glass tubes be connected side by side in factory, also can be with glass tube---and such as glass tube with vacuum, be transported to the scene earlier, then glass tube with vacuum arranged to bond to together side by side and can form stay-warm case.Independently glass tube transports convenient.Heat-sink shell can be selected various selective coatings for use, for example: vulcanized lead coating, aluminium nitrogen aluminium paint.
Glass tube among the present invention is arranged in planar shaped or curved surface shaped and matches with the shell shape at heat exchange container top, and high insulating effect, and simple installation can also adapt to the different heat exchange container of top shape.For example, being shaped as of heat exchange container is cylindrical, and glass tube is connected to form stay-warm case side by side along the top of heat exchange container, and the cross section semicircular in shape of stay-warm case matches high insulating effect with the top of heat exchange container.
Compared with prior art, the invention has the beneficial effects as follows:
Provide that a kind of manufacturing is simple, cost is low, transportation, simple installation are easy to safeguard, and the solar energy heat collector of thermal conversion rate preferably can be provided.Promptly solar water heater be can be applied to, closing-sunning type water heater or shallow pond formula water heater also can be applicable to.
