Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-4, an energy-saving curtain wall for cooling based on the solubility of a solution includes: a wall body 1.
As shown in fig. 1: the left side of the wall body 1 is movably provided with a curtain wall body 2.
As shown in fig. 2: 2 inside lower extreme fixed mounting of curtain body has fixing base 3, the upper surface of fixing base 3 has stock solution post 5 through 4 elastic connection of pressure spring, solution in the stock solution post 5 is mainly sodium chloride solution, secondly be iron oxide and titanium dioxide, mainly because sodium chloride arouses the change of solution specific heat capacity, mainly because after the temperature risees, the sodium chloride that solution can dissolve will increase, this process is an endothermic process, will be inhaled the heat out, thereby reach the effect of cooling, on the same way, the temperature of solution reduces, solubility in the solution will diminish, sodium chloride will be precipitated, reach used repeatedly's effect. Iron oxide and titanium dioxide are mainly because its specific heat capacity is little, and the cooling of absorbing heat easily, and 5 upper ends pegs graft of stock solution post have water storage column 6, and the inside of water storage column 6 sets up has water, and it is big mainly to utilize the specific heat capacity of water, realizes heat retaining effect easily.
As shown in fig. 3-4: dog 7 is passed through to the upper end of water storage column 6, fixed mounting has heat collection pole 8, there is heat preservation shell 10 in the both sides of heat collection pole 8 through ball 9 swing joint, ball 9's diameter and the side of heat collection pole 8 and the distance looks adaptation between the shell 10 inner wall that keeps warm, the back of heat preservation shell 10 and the inner wall fixed mounting of curtain body 2, the left side fixed mounting of heat preservation shell 10 has lens 11, lens 11's right side is pasted with the one deck membrane that looses, mainly be in order to pass the heat to elastic shell 12 at the focus, still avoided the heat to gather together through lens 11, light elastic shell 12, the effect that has protection elastic shell 12.
Wherein, through the cooperation of liquid storage column 5, water storage column 6, dog 7, heat collection pole 8 and ball 9 use, can the effectual change that utilizes specific heat capacity and liquid solubility, realize the purpose of cooling, the glass curtain wall who has guaranteed the deep color system heaies up more highly, and the cooling is more obvious, has energy saving and emission reduction safe harmless cooling advantage simultaneously.
The upper end fixedly connected with elastic shell 12 of heat collection pole 8, the inside lower extreme fixed mounting of elastic shell 12 has fixed block 13, the inside that fixed block 13 is located elastic shell 12 is the shape of different sizes, mainly be when receiving the thermal energy gradually for treating the gas in elastic shell 12, balancing weight 14 is the motion on the elastic shell 12 that is located of not equidimension, the upper end overlap joint of fixed block 13 has balancing weight 14, balancing weight 14 is located elastic shell 12 inside and sets up no less than three, mainly be the motion that utilizes balancing weight 14, drive the upper and lower shake of heat collection pole 8.
Wherein, use through the cooperation of lens 11, elasticity shell 12, fixed block 13 and balancing weight 14, can utilize gaseous expend with heat and contract with cold, arouse the change of balancing weight 14 positions in the elasticity shell 12 to shake from top to bottom through heat collection pole 8 drive liquid storage column 5, make more even that solution mixes. Wherein, the elastic shell 12 is made of a substance with high ignition point and large elasticity.
Wherein, the lower surface of the stop block 7 is fixedly arranged with the upper end of the liquid storage column 5.
Wherein, the specific heat capacity refers to the heat quantity required for increasing the temperature of a certain amount of homogeneous substances by 1K when no phase change or chemical change exists, and if the specific heat quantity is 1mol of substances, the required heat quantity is the molar heat capacity. The molar heat capacity Cp under isobaric conditions is called the constant pressure molar heat capacity, the molar heat capacity Cv under isochoric conditions is called the constant volume molar heat capacity, and the relationship between the constant pressure molar heat capacity and temperature is usually related to a polynomial expression.
Expansion with heat and contraction with cold: generally, under the condition of constant external pressure, most substances increase in volume when the temperature is increased; when the temperature is reduced, the volume of the product is reduced, and under the same condition, the expansion of the gas is maximum, the liquid is next to the liquid, and the solid is minimum.
The elastic shell 12 is filled with nitrogen, which is inert and is not easy to react with other substances.
When the solar liquid storage column is used, heat energy in sunlight is collected through the lens 11 and focused on the elastic shell 12, nitrogen in the elastic shell 12 is heated to expand, so that the elastic shell 12 gradually becomes swelled, the balancing weight 14 gradually moves on the fixing block 13 in the elastic shell 12 to drive the heat collection rod 8 to move up and down, the heat collected by the heat collection rod 8 is conducted to a solution in the liquid storage column 5, meanwhile, when the heat collection rod 8 moves up and down, the liquid storage column 5 is driven to move up and down, when the liquid storage column 5 moves up and down, the pressure spring 4 is driven to move up and down, so that the solution in the liquid storage column 5 is mixed more uniformly through continuous shaking of the pressure spring 4, the solubility of the solution in the liquid storage column 5 heated through the heat collection rod 8 is increased, more sodium chloride solution is dissolved, and the process is a heat absorption process, and heat can be absorbed, therefore, the effect of cooling is achieved, the temperature after cooling is transferred to the water storage column 6 through heat transfer, the heat preservation effect is achieved after cooling is achieved by means of the large specific heat capacity of water, the temperature of the solution is reduced, the solubility in the solution is reduced, the sodium chloride is separated out, and therefore the effect of repeated use can be achieved.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
