Transparent Panel Block for Heat Preservation and Thermal Insulation FIELD OF THE INVENTION This invention relates to the technology of transparent and heat preservation and thermal insulation by utilizing a transparent panel block for heat preservation and thermal insulation in architecture solar energy utilization. BACKGROUND OF THE INVENTION Buildings need transparent baffle for light transmission and thermal insulation. In practice, the performances of light transmission, heat preservation and thermal insulation are always taken into consideration, such as for windows of the buildings, baffles of glasshouse and the like. Doors and windows are the essential components of buildings, and 60% 80% of the energy consumption of the doors and windows is based on thermal conduction of the glass. Therefore, the energy efficiency for doors and windows mainly refers to the energy efficiency of the glass. The way of heat gain and heat loss of the doors and windows includes heat gain from solar energy, thermal conduction and air permeation. The energy efficiency technologies of doors and windows in the world currently experience the progress from passive energy efficiency to active energy conservation, i.e. moving from avoiding the incidence of sunlight towards actively utilizing the solar energy. At present, to adopt the energy rating system for windows and doors started from the developed countries which aims to rate the energy consumption of various windows during both the space heating season and space cooling season, for example, the Canadian ER system and American NFRC system. In those rating systems, the solar heat gain coefficient appears more important, while the thermal transmittance appears less important, and the influence of permeation coefficient almost can be ignored. Therefore, the key point of energy efficiency for doors and windows is to reduce the cost and space heating energy

consumption at the same time, by taking the solar heat gain coefficient, thermal transmittance and air permeation coefficient of windows in account together. The ideal energy-saving doors and windows should have a good performance of light transmission, thermal insulation and heat preservation. The effective way to increase the solar heat gain coefficient is to increase the ratio of the window frame to the area of window, and the ratio of the light transmittance, plus to control the layers of the glass. The effective way to increase the heat preservation and thermal insulation of doors and windows relates to several aspects. According to the test data, 50%-70% of the energy consumption of outside doors and windows is caused by thermal conduction. For the door and window of insulating glass structure and two-layer glass structure, the way of thermal transfer includes thermal radiation, conduction and convection, wherein the thermal radiation (including visible light and infrared light) accounts for nearly 60%, and its value of coefficient depends on the temperature difference between the inner surfaces of two glass panels and the radiance of the gas in the space there between. The current technology mainly employs the coating method to reduce the thermal radiation, for example, the method of using Low-E sputter coated two-layered insulating glass for thermal insulation which filled with dry air or inert gas to protect the coated layer, and a space of 6-9 millimeters is set to enhance the thermal insulation. Since the air leakage occurs inevitably during processing and using, the sputter processing coated layer cannot be protected properly all the time, therefore, the actual reliability is relatively low, and the lifetime of the Low-E insulating glass is often less than 10 years. In addition, as the light transmittance of the coated glass is generally below 70%, which significantly influence the energy-saving performance on raising solar heat gain coefficient for space heating. Secondly, the thermal conduction accounts for nearly 37%, which is mainly realized by the glass and the air therein, as air is the poor heat conductor, the increase of the air space thickness shows a significant effect on reducing the 2 thermal transfer based on thermal conduction, the value of which depends on the air space thickness between the interlayer. once the air space is set too thick, thermal transfer based on thermal conduction will rise dramatically. In general, the appropriate thickness for such air space is between 6 to 9 millimeters. Besides, the existence of active molecule such as the water molecule in air will also influence the thermal transfer based on the thermal conduction and thermal convection, therefore, the way of filling with dry air or inert gas between normal double glazing or triple glazing insulating glass for heat preservation is adopted. More the glass layers, better the heat preservation performance. The thickness of the glass used is range between 3 to 10 millimeters normally, therefore one more interlayer or a piece of transparent panel added, and thicker the frame, more the material and the weight will increased. When built architecture doors and windows, the setting of multiple interlayer for improving its performance in both heat preservation and heat insulation will increase the weight of the building, except the inconvenience for installation and utilization, it also increase the cost of the building as well as its doors and windows related components. Even the extra white glass with a light transmittance of 90% is used, the light transmittance will decrease by 10% when every one interlayer is added, which is not benefit to the energy-saving performance on improving the solar heat gain coefficient for space heating too, therefore, the number of the interlayer added is maximum three, and no more than three. The honeycomb structure is then developed after the insulating glass to inhibit convection and increase the thickness of the interlayer air space. The honeycomb structure posses a hydraulic diameter of normally between 5 to 10 millimeters, and a interlayer thickness of more than 25 millimeters often. Although it is better in heat preservation performance, but relatively lower in its light transmittance and poor in its visual comfort, besides, due to the complicated in manufacturing process and not so cost effective, it has been developed slowly. Accept that, the vacuum pumping is another way employed 3 to reduce the thermal transfer based on the thermal conduction. The average vacuum glass has a better energy-saving ability by 15-18% more than that of the insulating glass, but its manufacturing process is far more complicated and the cost is much higher, "A Common Used Vacuum Glass For Heat Preservation" disclosed in CN93228540 for instance, which employs two glass to form a vacuumed interlayer, wherein a group of transparent PVC hard plastic square grid is disposed between the interlayer, epoxy glue with high bonding strength is used to bond the glass bar, which help to seal and fix the two glass panels while conducting the vacuum pumping, and to inhibit the air convection and leakage from the interlayer, when using this method, the square grid will reduce the light transmittance significantly, especially when it is used in multistory building situation, the 'total weight of the building structure will increased, which has an obvious influence to the building foundation. Secondly, as the expansion coefficient of PVC is different from that of epoxy glue, and the cured epoxy glue is lack of elasticity, so the sealed structure will become loose and lead to the failure of vacuum under the cyclic stress caused by the temperature changing during hot summer and cold winter after a certain period, therefore, its service time and reliability of heat preservation is relatively lower. In addition, due to the extra high negative pressure exited inside interlayer normally, the vacuum glass is unsuitable for using in multistory building situation which often request for undertaking a heavy load such as higher wind pressure. The thermal transfer based on the thermal convection accounts for nearly 3%, the value of which depends on the thickness and temperature of the air space between glass panels. In general, for door and window the heat preservation means to inhibit the heat transferred from the inside to the outside in winter; vise versa, the thermal insulation means to inhibit the heat transferred from the outside to inside in summer, which mainly depends on its ability of blocking the sunlight. The current trend for glass energy-saving technique is moving towards possessing 4 both the property of heat preservation and thermal insulation simultaneously through the combination of different technologies and also improving both the performance of heat preservation and thermal insulation, meanwhile, with cost effective and a higher ratio in both heat preservation and in thermal insulation to the price as a standard for evaluation. It is a trend for two-layer glass or insulating glass panel to reach its technology breakthrough and development in field of heat transfer techniques through thermal conduction and thermal convection besides its thermal radiation, and accomplish energy-saving and building space heating by solar energy utilization. SUMMARY OF THE INVENTION The object of this invention is to provide a transparent panel block for heat preservation and thermal insulation for building energy-saving, which including a insulating glass transparent panel block for heat preservation and thermal insulation, wherein a plurality of horizontal parallel highly transparent polyester soft film wing panels are arranged within the transparent interlayer of the transparent panel block for heat preservation and thermal insulation, so as to form a convectivethermal transmission blocker which will not influence the light transmission, therefore, the space of transparent panel interlayer can be increased so as to increase the distance of thermal transmission of horizontal static air and reduce the heat loss coefficient without the limitation of the size of the space that usually cause the convection, therefore, the heat loss coefficient of the existing Low-E insulating glass for thermal insulation can be reached, meanwhile, the heat gain coefficient of the sunlight can be increased and a good reliability and excellent ratio of performance to cost can be obtained as well. This invention is accomplished as following: the invention employs a transparent panel block for heat preservation and thermal insulation, which comprises transparent panels; and a frame, wherein sealing strips or spacing 5 strips and a sealant can be disposed at the edges of a two-layer transparent panel formed by sandwiching two transparent panels, wherein the interlayer is airproof, with appropriate gas such as dry air or inert gases filled therein to restrain up and down convection or reduce heat transfer coefficient, which is characterized in that a plurality of parallel transparent wing panels are further disposed horizontally and parallel to each other along a longitudinal direction in the interlayer, which are fixed on the two sides of the frame in the interlayer, said transparent wing panels are highly transparent polyester polymer plastic soft films with a thickness below 0.15 millimeters, and when the space of the interlayer is an optimal value of 16-60 millimeters, the corresponding optimal value of the distance between the transparent wing panels ranges from 4 to 17 millimeters. The highly transparent polyester polymer plastic soft films are chemical films which have a light transmittance of at least >80% and a long service life of continuous using and are resistant to ultraviolet aging, such as highly transparent polyurethane (PU) soft films or highly transparent polycarbonate (PC) soft films or highly transparent polyester(PET) soft films and the like. With a light transmittance of >80%, said highly transparent polyester polymer plastic soft film may be provided with a functional film on its skin layer, such as a broadband reflection-reducing coating, or a broadband anti-electromagnetic-wave absorption coating. The transparent wing panels are a plurality of parallel transparent wing panels formed by folding and winding a continuous trip left and right from top to bottom and fixing them on the both sides of the frame within the interlayer, the transparent wing panel soft film is elastic or non-elastic, wherein the non-elastic soft film has an end fixedly connected to the frame, and the other end fixedly connected to the frame through an elastic connector. The plurality of parallel transparent wing panels disposed longitudinally and horizontally may be arranged equidistantly, or arranged at different distances from the top and bottom ends to the middle part. The width of said transparent wing panels is set such that their distances to the two-layer transparent panel block on the both sides are not greater than 5.2 6 millimeters each. The space of the interlayer is a distance suitable for thermal insulation and heat preservation of the two-layer transparent panel block, which ranges from 8 to 200 millimeters, and the optimal value of the space of the interlayer of 16-60 millimeters is a distance which makes the ratio of performance to cost of the transparent panel block most preferred under the condition of a total light transmittance not less than 60%. The ratio of the width (B) of the transparent wing panels to the arranged space ( 8 ) is between 1.5 to 40. On the horizontal plane of said transparent wing panels, there may be one or more strips of the same material and properties and thickness as the transparent wing panels, which are hung downwards and have a height of 15%-50% of the space of the transparent wing panels and are separated from front to back. The transparent panel consists of two single layers or one single layer with a two-layer insulating glass transparent panels unit. Said transparent wing panel can be set between the two single layers or between one single layer and one insulating glass transparent panels unit. The parallel disposition of the transparent wing panels may be in such that their surfaces are parallel to the horizontal plane, or that their surfaces is angled by 0-75 degree relative to the horizontal plane depending on the various requirements of heat preservation or thermal insulation situation and the fluctuate of the geographical latitude. The advantages of this invention lies in that: with the arrangement of heat convection blocker of highly transparent polyester soft films, it is capable to inhibit the convection or re-flowing of the longitudinal air in the interlayer and to increase the dimension setting range of the pitch of air space for thermal insulation, therefore, the pitch of the interlayer space can be increased and the corresponding effect for thermal insulation can be strengthened in the case that the light transmittance of the transparent panel for thermal insulation nearly remains unchanged; as the distance and damping of the thermal transmission by horizontal static air is increased, the heat loss coefficient of the transparent. panel for thermal insulation and heat preservation is reduced significantly, such 7 that it can reach the level of current Low-E insulating glass for thermal insulation, and the same heat gain coefficient as the vacuum glass is kept at the same time, however, it has a more steady performance reliability of heat preservation and provides a higher ratio of performance to cost. Some detailed application with this invention for achieving a better effect is described by comparison as follow: as the loss of light transmittance for multi-layer light transmission structured panel is reduced, according to one of its applications for transparent thermal insulation and heat preservation panel block, such as in case of being used for windows, for which the highly transparent material with high light transmittance is required, in situation of reach the same performance level in heat preservation and heat loss, the light transmittance of the transparent thermal insulation and heat preservation panel can increase significantly when compare with the same window in honeycomb structure; meanwhile, it can reach the same highest overall light transmittance level as the vacuum glass does, in visual comfort aspect, it is much better than that of the honeycomb structured glass and Low-E insulating glass, comparing on its service time and heat preservation reliability aspect, the transparent thermal insulation and heat preservation panel can reach a much higher performance level to that of vacuum window panel and Low-E insulating glass transparent window panel; since the number of the transparent layer for thermal insulation will not increase in any case, as a result, its weight is relatively reduced, and its manufacture and relevant cost is more effective; furthermore, the complexity of its process and cost for application are much lower than that of vacuum transparent thermal insulation window panel and honeycomb light transmission thermal insulation window panel. According to the application two: with "Single-framed steel-plastic extrusion casement window with double glazing", the Chinese Standard GB8484, in temperature condition of 20'C, the test result by comparison are as follow: Single-framed steel-plastic extrusion casement Single-framed wing-type steel-plastic window with double glazing extrusion casement window with double 8 glazing Air space Glass 50% vacuum Air space Distance between Glass thickness thickness level thickness wing panels thickness Unit (mm) 6 3 With sealed 40 12.5 3 Heat loss coefficient 2.9 2.5 42.0

DETAILED DESCRIPTION OF THE INVENTION As shown in Fig.1 and Fig.2, the embodiment One of a transparent panel block for heat preservation and thermal insulation of this invention is a wing-type transparent insulating glass consisting of two transparent panels 1, a frame 2, a wing panel 3 and a sealing strip 4, wherein the transparent panels 1 employ extra white plate glass and highly transparent acrylic acid panel with a 9 light transmittance of >90%, and a thickness of 4 millimeters and 3 millimeters respectively. The frame 2 is composed of aluminum spacing strips of insulating glass with fixed strip or support frame, wherein sealing strip 4 or aluminum space strip and sealant 4 can be disposed at the edges of a two-layer transparent panel formed by sandwiching two transparent panels, wherein the interlayer is airproof, with appropriate gas such as dry air or inert gases (e.g. argon) charged therein to restrain up and down convection or reduce thermal transmittance. A plurality of parallel transparent wing panels are further disposed horizontally and parallel to each other along a longitudinal direction in the interlayer, which are fixed on the two sides of the frame in the interlayer by folding and winding a continuous highly transparent polyurethane (PU) soft film left and right from top to bottom. As shown in Fig. 1, the transparent wing panels can be arranged equidistantly and parallel to the horizontal plane. The thickness of transparent wing panels should be 0.01-0.15 millimeters, when thickness is 0.05 millimeters for instance, its light transmittance is >90%. According to the experience, the width of the transparent wing panels is set in such that their distances to the two-layer transparent panel block on the both sides are not greater than 5.2 millimeters each, wherein, the distance between said transparent wing panels to the two-layer transparent panel block should not greater than 2.6 millimeters each. Said interlayer space refers to the distance suitable for thermal insulation and heat preservation of the two-layer transparent panel block, which ranges from 8 to 200 millimeters according to experience, and the optimal value of the interlayer space is of 16-60 millimeters, which is a distance makes the ratio of performance to cost of the transparent panel block most preferred under the condition of a total light transmittance not less than 60%, thus to ensure that the heat loss coefficient, which represents the performance of heat preservation within the optimal value range, is better than the optimal value of heat loss coefficient for the transparent insulating glass (glass is uncoated) of 2.5 (W/M 2 K) within the same range of dimension. In order to obtain an effect of visual 10 comfort, the ratio of its width (B) of the transparent wing panels to its arranged space ( 5 ) should be between 1.5 and 40. When the interlayer space of the transparent panel block ranges from 34-54 millimeters, accordingly the arranged space ( 6 ) between the transparent wing panels ranges from 6-14 millimeters within its optimal range of 4-17 millimeters, and the width (B) of transparent wing panels is from 30-50 millimeters, then the ratio of the width of the transparent wing panels to the arranged space is between 3.5 and 5, the optimal value of the total light transmittance of the transparent panel block can be over 79%, which is similar to that of vacuum glass and just a bit lower than the optimal total light transmittance of 81% level of the transparent insulating glass, the optimal heat loss coefficient can be lower than 1.8(W/M 2 K), which is far more superior than the optimal heat loss coefficient of 2.5 (W/M 2 K) of the said transparent insulating glass within the same range of dimension. In order to obtain an high light transparent result for a long-term, said highly transparent polyester polymer plastic soft films are chemical films which have a light transmittance of at least & 80% and a long service life for continuous using, maintain its high light transmittance over 5 years under sunlight, and also are resistant to ultraviolet aging. As shown in Fig.3, the embodiment Two of transparent panel block for heat preservation and thermal insulation is a single framed transparent insulating glass wall panel for heat preservation and consist of two transparent panels 1, frame 2, wing panel 3, sealant and aluminum spacing strip 4, and spacing strip 5, among them: the frame 2 is composed of an aluminum alloy frame, wherein insulating glass aluminum spacing strips with fixed step is disposed on the inner side of the frame, which is fixed and sealed to the frame and two transparent glass by using silica gel and butyl gel. The two transparent panels 1 adopt the float-produced glass with a light transmittance of >, 87% and a thickness of 10 mrnilimetery, pd the interlayer space between them is 60 11 millimeters. The spacing strip adopt the continuous highly transparent polycarbonate (PC) non-elastic soft film strip fixed in parallel to the both sides of the interlayer window frame, wherein the strip has its one end connected to the frame and the other end fixed to the frame through an elastic connector. A supporting bracket can be arranged in the middle part of the spacing strip to support the glass with large width and the middle part of the spacing strip. The transparent wing panels are arranged at different distances from the top and bottom ends to the middle part, wherein the distance between the top and bottom wing panels are 8 millimeters and the distance between the middle wing panels is 12 millimeters. In this way, the middle part can have a better clear visual effect. The soft film made strip wing panel 3 is provided with highly transparent spacing strips 5 made of the same material on its plane, which are hung downwards and are separated from front to back. The thickness of both strips is 0.15 millimeters and the light transmittance should be >90%. The spacing strip connect structure hanging downwards shown in Fig.3 is formed by folding one side of the spacing strip and bonding it with the midline of the wing panel by heat melting. The height of the strip should be 15%-50% of the space between the transparent wing panels, which forms damping or barrier for the airflow back and forth on the upper portion of each spacing interlayer. This kind of spacing strip hanging downwards can be arranged as a single strip or several strips, according to the distance between interlayer. The width (B) of wing panels is 50 millimeters and the ratio of both the width of top and bottom end of the wing panels and the width of middle part of the wing panels to the arranged space is respectively 3.125 and 4.16. In this way, the number of layers of the lower wing panels through which part of the direct sunlight transmitted through can be decreased, so that the total performance of light transmittance of the transparent panel block will not reduced. The wing panels may be set in such that their surface is angled by 0-75 degree related to the horizontal plane depending on the various application requirements for heat preservation or thermal insulation and the fluctuate of the 12 geographical latitude, and the wing panels are fixed in parallel to both sides of the sandwiching window frame. For example, during the summer, the sunlight is strong and the high temperature season is quite long, the wing panels should be angled by 0-5 degree in the low latitude area, and the wing panels with a light transmittance of 80% is suitable for turn incident light entering the room into diffused light after been transmitted and reflected through the transparent wing panels, thus to avoid the glaring direct light. During the winter, the sunlight is weak and the low temperature season is relatively long, the highly transparent wing panels can be angled to approximate 45 degree in intermediate and high latitude area, such as Haerbin city in China. The advantage is that the arrangement is suitable for the incident light to directly pass through the highly transparent wing panel space or entering the room after partially reflected and transmitted by the highly transparent wing panels. In this way, the strength of the direct light indoor can be obtained well while ensuring the performance of heat preservation. As shown in Fig.4, the embodiment Three of a transparent panel block for heat preservation and thermal insulation in this invention is a wing-type single-framed sandwiching double glazing half-transparent door for heat preservation, which is composed of two transparent panels 1, frame 2, wing panel 3, sealant and aluminum spacing strip 4, and compound sealing strip 6, wherein, the aluminum spacing strip is provided with steps for fixing the wing panel strip on the inner side. Transparent panel 1 is composed of one single-layer glass and one two-layer insulating transparent panel unit, such as insulating glass, which all employ plate glass having a light transmittance of > 87% and a thickness of 8 millimeters, the transparent wing panels are disposed between a single-layer glass and a two-layer insulating glass transparent panel unit, and the insulating glass is separated by and sealed with compound sealing strip 6, frame 2 is made of plastic, and aluminum spacing strips is disposed between the single-layer glass and the insulating glass, which is sealed with the glass by using butyl glue and fixed to the frame 2 by using 13 polysulphide glue sealant. The wing panel 3 can be formed by using polyester (PET) non-elastic soft film having a light transmittance of 90% and also with some diffusion effect, can be used for light transmitting and blocking the visual interference. The thickness of the transparent wing panel is 0.05 millimeters and the width (B) of the transparent wing panel is 23 millimeters, and the distance between the wing panels to both two-layer transparent panel blocks is 0.5 millimeters each. The space of the interlayer is 24 millimeters and the arranged space ( 8 ) of wing panels is 8.25 millimeters, the ratio of the width of wing panel to the arranged space is 2.78, and the surface of wing panel is angled by 45 degree related to the horizontal plane. The wing panel is fixed in parallel on the step for fixing the aluminum spacing strips on both sides of the interlayer doorframe according to the embodiment Two. The advantage is that the arrangement of 45 degree wing panel, when applying to the glass door inside the office building for both light transmittance and heat preservation, is capable of sharing the office environment and avoiding the visual interference so as to create a comfortable working environment. In addition, with a light transmittance of >80%, the highly transparent polyester polymer plastic film may be provided with a functional film on its skin layer. For example, the polyester (PET) non-elastic soft film can be provided with a nanometer silicon dioxide cross-linking network-type broadband reflection-reducing coating or a broadband anti-electromagnetic-wave absorption chemical coating surface modified on its skin layer, so as to reduce the light pollution when used as outside door and window as well as to reduce the interference caused by outside electromagnet wave to the inside working equipments. Taking the application utilized in the northern hemisphere for an example, including reducing the heat loss coefficient of transparent panel block for thermal insulation and heat preservation and raising its heat gain coefficient for energy-saving, the working principle of the transparent panel block for heat presrvation an thermal insylipn is that: in the winner, 7.4% of the midday direct sunlight will be reflected, 'the other part of the sunlight will enter the 14 interlayer of two-layer transparent panel block, the sunlight enters into the room through the inner transparent panel after passing through the parallel wing panels to the interlayer, the light transmittance changes according to the vertical angle of the sunlight, the total light transmittance can reach nearly 0.7 sometime when the sunlight entering the room after reflected by the wing panels. room heat will warm up the air within the interlayer through the conduction of inner transparent panel. Since the up and down air convection is blocked by the wing panels disposed in parallel, the horizontal heat transfer speed (with or without the block of spacing strips) is much slower than the heat transfer speed in the presence of convection up and down, when the space of wing-type transparent insulating glass panel for thermal insulation and heat preservation is 40 millimeters and the space between wing panels is 12.5 millimeters, the heat loss coefficient (W/M 2 K) is reduced by about 30% than two-layer transparent insulating glass panel for heat preservation, which has the maximum space of 6 mm-9 mm without convection.
