Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The regularity of distribution of the heat flow density in the heat-absorbing chamber of focusing-type solar energy heat dump is: intermediate heat current density is the highest, radially reduces gradually.Thus, the heat absorption coil pipe being positioned at heat-absorbing chamber centre position is more owing to being heated, and easily burns.For this reason, the invention discloses a kind of novel focusing-type solar energy heat dump.
The structural representation of a kind of W type of the present invention Columnating type solar heat dump is shown see Fig. 1.In the present embodiment, this heat dump comprises: shell 1, be positioned at the heat-absorbing chamber 2 of shell 1 inside, be arranged at the bottom of heat-absorbing chamber 2, by the sunshine non-uniform reflection that is irradiated to bottom heat-absorbing chamber 2 to the reflection unit on heat-absorbing chamber 2 sidewall.Wherein, attachment heat absorption coil pipe 3 on the sidewall of heat-absorbing chamber, this heat absorption coil pipe is divided into inside and outside two-layer, and internal flow has heat absorption working medium, and this heat absorption working medium temperature under the irradiation of solar energy raises, thus solar energy is converted to heat energy.
It should be noted that, this reflection unit comprises: curved reflecting surface 4, and curved reflecting surface 4 to be rotated around rotary middle spindle by satisfactory curve and forms.This curved reflecting surface 4 has identical tip, and is bolted to connection, and the periphery of curved reflecting surface 4 is all connected with the bottom margin of heat-absorbing chamber 2.Like this, when solar irradiation is mapped to curved reflecting surface 4, curved reflecting surface 4 by sunshine non-uniform reflection on the sidewall being positioned at the corresponding heat-absorbing chamber of this curved reflecting surface 42, thus can avoid the direct irradiation of sun pipe to heat absorption coil pipe 3.
In addition, be furnished with heat absorption coil pipe 3 equally in the below of curved reflecting surface 4, for absorbing the heat that reflection unit passes over, reduce the temperature of reflection unit, improve the utilization rate of solar energy simultaneously.
In the technological design of reality, in order to fix this curved reflecting surface 4.This reflection unit also comprises: the support arm 5 being arranged at heat-absorbing chamber 2 center.
The connection layout of the reflection unit of a kind of W type of the present invention Columnating type solar heat dump is shown see Fig. 2.
One end of this support arm 5 is connected with the tip of curved reflecting surface 4, and the other end runs through heat-absorbing chamber 2 and the shell 1 of heat dump, and is connected with the base plate 6 be positioned at below shell.Wherein base plate 6 and shell 1 are provided with screwed hole, and by being connected with the bolt 7 that this screwed hole matches.
It should be noted that, in the present embodiment, the tip of curved reflecting surface 4 goes out to be embedded with nut 8, and this support arm 5 is connected with this tip by the screw thread being arranged on support arm 5 one end, reaches the object of fixing curved reflecting surface 4.
Optionally, in order to prevent heat in heat-absorbing chamber 2 to external diffusion, improving the utilization rate of solar energy, preventing outside pollutant such as: dust, enters heat-absorbing chamber 2, causes damage to heat-absorbing chamber 2 simultaneously.In the present invention, the top of this heat-absorbing chamber 2 is also provided with transparency glass plate 9.Meanwhile, in the space between heat-absorbing chamber 2 and shell 1, be also filled with heat-insulating material 10, to avoid heat-absorbing chamber 2 and external environment generation heat exchange as much as possible.
It should be noted that, in order to more solar irradiation is mapped in heat-absorbing chamber 2.Optionally above the shell of this heat dump, also can arrange an arc-shaped reflecting mirror (not shown in FIG.), sunshine, after the reflection of arc-shaped reflecting mirror, forms the sun light beam assembled and is irradiated in heat-absorbing chamber 2.
But due in the manufacturing process of reality, due to processing technology, this type speculum occurs error in processing, the sunshine that part is reflected by arc-shaped reflecting mirror is caused not shine directly in heat-absorbing chamber 2.For this reason, in the present invention, this heat dump also comprises: the ceramic protective sleeve 11 being arranged on the accent both sides of heat-absorbing chamber 2.
Wherein, the opening of this ceramic protective sleeve 11 is towards the direction of curved reflector; and design the angle of dehiscing of heat dump ceramic protective sleeve according to the subtended angle size of curved reflector, for the sunshine secondary counter reflexed on heat dump protective sleeve is injected in heat-absorbing chamber 2 directly not entering heat absorption accent.Wherein, the transparency glass plate 9 of above-mentioned introduction is arranged between ceramic protective sleeve 11 and shell 1, and this ceramic protective sleeve 1, transparency glass plate 9 and shell 1 are provided with screw thread mouth, and three is fixedly connected with connected by bolt 12.
It should be noted that, usually arrange a heat absorption coil pipe in the heat-absorbing chamber of traditional heat dump, pipeline is longer, reduces the utilization rate of solar energy.Relatively with traditional heat dump, in the present invention, in the heat-absorbing chamber 2 of heat dump, be furnished with many heat absorption coil pipes, many heat absorption coil pipe independent heat exchange to each other, be conducive to cavity temperature even, improve the utilization rate of solar energy.
In this description, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
