Description

玻璃金属副过渡连接装置及其在太阳能真空集热管中的应用所属领域 Glass-metal pair transition connection device and application thereof in solar vacuum heat collecting tube

本发明涉及一种玻璃金属封接技术，具体地讲是一种针对太阳能真空集热管的玻璃金属封接。 The invention relates to a glass-to-metal sealing technology, in particular to a glass-to-metal sealing for a solar vacuum heat collecting tube.

背景技术 Background technique

太阳能是一种取之不尽的绿色能源。在太阳能的利用中，通常采用一种太阳能真空集热管，将太阳能的热量有效地收集起来。这种太阳能真空集热管包括有玻璃管，该玻璃管内设有金属吸热体，最佳的技术方案将玻璃管内呈真空状态，以最大限度地减少热能的损失。金属吸热体至少有一端伸出于玻璃管的外端，并连接于热能所需的装置，如水箱等。为保持玻璃管内的真空状态，必' 须解决玻璃管与金属吸热体的伸出端的密封连接问题。 Solar energy is an inexhaustible source of green energy. In the use of solar energy, a solar energy vacuum heat collecting tube is usually used to effectively collect the solar heat. This solar vacuum heat collecting tube includes a glass tube, and a metal heat sink is provided in the glass tube. The best technical solution is to put the inside of the glass tube in a vacuum state to minimize the loss of thermal energy. At least one end of the metal heat sink protrudes from the outer end of the glass tube, and is connected to a device required for thermal energy, such as a water tank. In order to maintain the vacuum state in the glass tube, the problem of the sealed connection between the glass tube and the protruding end of the metal heat sink must be solved.

传统的玻璃金属封接一般采用火焰封接的方法，将被封接的玻璃和金属熔接在一起。该方法要求被封接的玻璃和金属之间的膨胀系数非常匹配，相互间的差值小于 6%。为了满足这一条件，在封接时需对玻璃进行高温加热，然后再对玻璃进行退火，以消除熔接时造成的热应力。但是，利用这种常规的封接方法，应用于太阳能真空集热管两端进行封接时则造成极大的困难。因为，在进行火焰热封时，必须对较长的玻璃管进行整体加热，由于玻璃管较长，对玻璃管的加热处理不仅工艺过于复杂，而且能源消耗极大，生产效率也受到限制。由于该工艺技术成熟，目前大多数的国家的生产厂家一般均采用此种封接的方法。 Traditional glass-to-metal sealing generally uses a flame sealing method to fuse the sealed glass and metal together. This method requires that the expansion coefficients of the sealed glass and metal are very matched, and the difference between them is less than 6%. In order to meet this condition, the glass needs to be heated at high temperature during sealing, and then the glass is annealed to eliminate the thermal stress caused by welding. However, using this conventional sealing method causes great difficulties when applied to sealing both ends of a solar vacuum heat collecting tube. Because when flame heat-sealing is performed, the long glass tube must be heated as a whole. Because the glass tube is long, the heat treatment of the glass tube is not only overly complicated, but also consumes a lot of energy and limits production efficiency. Due to the maturity of this process technology, manufacturers in most countries currently generally adopt this method of sealing.

上述火焰封接的方法是基于玻璃与金属的热膨胀系数相对接近的情况，因此对玻璃管材和金属材料的选择要求较高。目前，在国内现有的玻璃管生产厂家所能提供的玻璃管材料未能找到能够满足与其匹配的金属材料，所以还不能采用上述熔封的工艺生产太阳能真空集热管。为此，北京市太阳能研究所经多年的研究提出一种热压封技术，即中国发明专利 93101627. 4。该专利公开了一种热压封技术，利用该技术，可以在较低的温度下，对集热管的玻璃法兰端面与金属端盖间通过一种铅基进行固态的封接，即在焊接材料保持因态的状态下通过适当的加压，使其封接在一起。这样，不仅使工艺大大简化，同时也解决了玻璃管材料和与之封接的金属材料之间膨胀系数不匹配所造成的困难。 The above flame sealing method is based on the fact that the thermal expansion coefficients of glass and metal are relatively close, so the selection of glass tubes and metal materials is high. At present, the glass tube materials that can be provided by existing glass tube manufacturers in China have not been able to find a metal material that can match them, so the above-mentioned fusion sealing process cannot be used to produce solar vacuum heat collection tubes. To this end, the Beijing Solar Energy Research Institute has proposed a hot compression sealing technology after years of research, that is, Chinese invention patent 93101627.4. This patent discloses a thermocompression sealing technology, which can be used to lower the glass flange end face of a heat collecting tube at a lower temperature. A solid seal is made between the end cap and the metal end cap, that is, the welding material is sealed by appropriate pressure while the material is kept in a state. In this way, not only the process is greatly simplified, but also the difficulties caused by the mismatch of the expansion coefficients between the glass tube material and the metal material sealed with it are solved.

热压封技术是属于材料固态焊接技术中的一种特殊的焊接方法，解决问题的关键是对封接件进行加热和加压，使其在连接处产生微量的塑性变形，进而发生原子间的相互扩散来实现封接的。缘此，热压封技术要解决的一个关键性的问题，是在对封接部位进行加热之后，向玻璃管封接的端面施加一 40- 150kg/cm²的冲击压力, 一般情况下冲击时间为 0. 5 s。由于玻璃管的长、径比较大，要使细长状玻璃管不被压碎，必须对该冲击压力进行精确控制，另外，对玻璃管的形状也有极其严格要求。该专利所采用的解决方法是，将玻璃管的端面制成法兰形式，在该法兰的下端面设定支撑，使得该冲击压力完全由法兰承接，从而减少了对玻璃管本身的形状要求。这个关键问题的解决使得热压封技术成为当前太阳能真空集热管生产的最佳方案。 '但使用实践证明，这种热压封技术还存在有如下缺陷： Hot compression sealing technology is a special welding method in the solid-state welding technology of materials. The key to solving the problem is to heat and pressurize the seal, causing a small amount of plastic deformation at the connection, and then interatomic Mutual diffusion to achieve sealing. For this reason, a key problem to be solved by the hot compression sealing technology is to apply an impact pressure of 40-150kg / cm ^{2 to} the end surface of the glass tube seal after heating the sealing portion, and the impact time under normal circumstances 5 s. Because the length and diameter of the glass tube are relatively large, in order to prevent the slender glass tube from being crushed, the impact pressure must be accurately controlled. In addition, the shape of the glass tube also has extremely strict requirements. The solution adopted by the patent is to make the end surface of the glass tube into a flange form, and set a support at the lower end surface of the flange, so that the impact pressure is completely received by the flange, thereby reducing the shape of the glass tube itself. Claim. The solution of this critical problem makes the heat-sealing technology the best solution for the current production of solar vacuum heat collecting tubes. 'But the practice has proved that this hot-seal technology also has the following defects:

一、生产设备复杂。为实现大批量的生产，采用如前所述两种的方法必须由特殊的专用生产线完成。太阳能真空集热管是一种细长的管子，无论采用热 . 压封技术，还是采用火焰熔接技术，所生产集热管均是在事先加工好的玻璃管：:' 上进行封接，因此，生产过程中必须将玻璃管小心地传送至各个不同的工位，由于玻璃管易碎的特性，所以其所需的生产线是极其庞大的而且结构复杂，这样使得集热管的生产成本因此而被提升。 First, the production equipment is complicated. In order to achieve mass production, the two methods described above must be completed by special dedicated production lines. The solar vacuum heat collecting tube is a kind of slender tube. No matter it adopts heat, pressure sealing technology or flame welding technology, the produced heat collecting tube is sealed on the glass tube: ', which has been processed in advance. Therefore, production During the process, the glass tube must be carefully transferred to various stations. Due to the fragile nature of the glass tube, the required production line is extremely large and the structure is complicated, which increases the production cost of the heat collecting tube.

二、真空集热管的长度受限制，在采用热压封技术时，必须垂直于玻璃管端面的对玻璃管的施压，目前所采用的方法是在生产线的施压工位是向地下延伸，因此，必须在该工位处具有一个向地下延伸的至少与玻璃管等长的深度。 2. The length of the vacuum heat collecting tube is limited. When the heat-sealing technology is used, the pressure on the glass tube must be perpendicular to the end face of the glass tube. The current method is to extend the pressure station of the production line to the ground. Therefore, it is necessary to have a depth at the station that extends at least as long as the glass tube.

这样，不仅增加了生产线的复杂性，而最重要的是因此限制了真空集热管的长度，目前采用热压封技术生产太阳能集管的最大长度为 2 米。随着太阳能的大规模利用，这种长度的集热管是远远不能满足使用需求的。 In this way, not only the complexity of the production line is increased, but the most important thing is that the length of the vacuum heat collecting tube is limited. At present, the maximum length of the solar collecting tube produced by the heat compression sealing technology is 2 meters. With the large-scale utilization of solar energy, heat collector tubes of this length are far from meeting the needs of use.

三、产品的规格受到限制，从另外一个角度讲，由生产线制造的产品所具有的共同缺陷是规格单一，即当制造生产线确定后，其产品的直径、长度规格以及结构即被确定，或者被限制在一个较小的范围内，而 _难再进行规格和结构上的的改变或者增加。 3. The product specifications are limited. From another perspective, the common defect of products manufactured by the production line is that the specifications are single, that is, when the production line is determined, the diameter, length specifications and structure of the product are determined, or Limited to a small range, and it is difficult to make specifications and conclusions again Structural changes or additions.

四、废品损失大，由于在整个加工的过程都是在预先加工好的玻璃管上完成的，因此，在热压封时出现废品则会使得整个玻璃管随之报废，无形中增大了废品的损失。 4. There is a large loss of waste products. Because the entire processing process is completed on pre-processed glass tubes, the occurrence of waste products during heat-seal will cause the entire glass tube to be scrapped, which will increase the waste products virtually. Loss.

通过分折不难看出，上述缺陷实质上是由玻璃管与金属端盖间的直接连接结构所造成的。而这些缺陷使.得太阳能真空集热管的制造难度增大了，也是目前太阳能技术利用的和推广的一个重要的障碍。 It is not difficult to see through the folding that the above defects are essentially caused by the direct connection structure between the glass tube and the metal end cap. These defects make the manufacturing of solar vacuum heat collecting tubes more difficult, and it is also an important obstacle to the utilization and promotion of solar energy technology.

发明概述 Summary of invention

本发明的目的在于提供一种玻璃金属副过渡连 4ί装置，利用该过渡连接结构，大大地简化真空集热管的玻璃与金属的封接工艺，简化其生产设备，并因此降低真空集热管制造成本。 The purpose of the present invention is to provide a glass-metal pair transitional connection device, which uses the transitional connection structure to greatly simplify the glass-to-metal sealing process of a vacuum heat collecting tube, simplify its production equipment, and therefore reduce the manufacturing cost of a vacuum heat collecting tube. .

本发明的另一目的则在于提供一种玻璃金属副过渡连接装置，通过该过渡连接结构的规格以及结构的变化，使得真空集热管的规格以及结构的变化更为简单易行，同时又能极大地降低真空集热管的废品损失率。 Another object of the present invention is to provide a glass-metal secondary transition connection device. Through the transition connection structure specification and structural change, the specification and structure change of the vacuum heat collecting tube are simpler and easier, and meanwhile, The earth reduces the waste loss rate of the vacuum heat collecting tube.

本发明的目的是这样实现的；一种玻璃金属副过渡连接装置，由玻璃连接件和金属连接件构成，该玻璃连接件和金属连接件至少设有一个相应的通孔，并沿该通孔的周边封接在一起；玻璃连接件设有可与玻璃管封接的连接端，金属连接件设有可于金属吸热体封接的连接端。 The object of the present invention is achieved in this way; a glass-metal secondary transition connection device is composed of a glass connection member and a metal connection member, and the glass connection member and the metal connection member are provided with at least one corresponding through hole, and along the through hole The perimeter of the glass connector is sealed together; the glass connector is provided with a connection end that can be sealed with a glass tube, and the metal connector is provided with a connection end that can be sealed with a metal heat sink.

本发明的玻璃连接件和金属连接件的封接方式可实施为热压封和火焰熔接两种。玻璃连接件可为适合于与玻璃管封接的不同形状。金属连接件可为适合于与吸热体封接的不同形状。 The sealing methods of the glass connector and the metal connector of the present invention can be implemented as two types: heat-pressing and flame welding. The glass connector can have different shapes suitable for sealing with glass tubes. The metal connecting member may have different shapes suitable for sealing with the heat sink.

如上述，太阳能真空集热管基本构造包括有外层的玻璃管，该玻璃管内设有金属吸热体，该金属吸热体将其所吸收的热量由该伸出端传通于玻璃管外。为防止热量的流失，玻璃管内必须呈真空状态，因此，解决的金属管与玻璃管之间的封接构成制造真空集热管的关键问题。而本发明利用一个结构极其筒单的的玻璃金属副过渡装置，使得真空管制造过程中的玻璃与金属之间的封接难题转变成金属与金属、玻璃与玻璃之间的同种材料的封接，而且这种金属与金属、玻璃与玻璃之间的封接可采用常规的技术即可实现，从而大大地简化了真空集热管的生产工艺，而不必再需要庞大而复杂的生产线，使得太阳能利用技术的推广成为可能。 As described above, the basic structure of the solar vacuum heat collecting tube includes a glass tube with an outer layer. The glass tube is provided with a metal heat sink, and the metal heat sink transmits the heat absorbed by the protruding end to the outside of the glass pipe. In order to prevent the loss of heat, the glass tube must be in a vacuum state. Therefore, the sealed seal between the metal tube and the glass tube constitutes a key problem in manufacturing a vacuum heat collecting tube. The present invention utilizes a glass-metal secondary transition device with a very simple structure, so that the sealing problem between glass and metal in the manufacturing process of the vacuum tube is turned into the sealing of the same material between metal and metal and between glass and glass Moreover, this metal-to-metal, glass-to-glass sealing can be achieved using conventional techniques, thereby greatly simplifying the true The production process of the empty collector tube, without the need for a large and complicated production line, makes the promotion of solar energy utilization technology possible.

首先，本发明中的玻璃金属副过渡连接件结构极其简单，其玻璃连接件相对于玻璃管形状要简单得多，体积也小得多，因此可采用现有各种金属、玻璃封接技术，而不需要复杂的生产工艺和庞大的生产线。当采用火焰熔封技术时，仅对该小体积的玻璃连接件的材料进行选择，而不必对整个玻璃管进行材料选择；当采用热压封技术时，基本上呈盘状的玻璃连接件结构本身即是最佳的承压结构，对加热和加压的要求均不高，而且由于其体积小，也极容易控制，所以本发明的玻璃金属副过渡连接装置的制造不必依赖于复杂的生产线。 First, the structure of the glass-metal secondary transition connector in the present invention is extremely simple. The glass connector is much simpler in shape than the glass tube, and its volume is much smaller. Therefore, various existing metal and glass sealing technologies can be used. Without the need for complex production processes and large production lines. When the flame fusion sealing technology is used, only the material of the small-volume glass connector is selected, and the material selection of the entire glass tube does not have to be selected. When the heat-compression sealing technology is used, the glass connector structure is basically disc-shaped. It is the best pressure-bearing structure in itself, and does not have high requirements for heating and pressurization, and because of its small size and easy control, the manufacturing of the glass-metal secondary transition connection device of the present invention does not need to rely on a complex production line .

由于本发明的玻璃金属副过渡连接装置结构筒单，制造容易。依据玻璃连接件，利用常规的玻璃熔接技术直接封接于玻璃管，而不再需要在玻璃管上加工出承受冲压力的法兰，简化了玻璃管的结构，而且在操作时不必将玻璃管竖直放置，所以，玻璃管的长度可依需要延长，制造成本被降低了，这会更加有利于扩大太阳能利用的规模。 Because the glass-metal secondary transition connection device of the present invention has a simple structure, manufacturing is easy. According to the glass connector, conventional glass welding technology is used to directly seal the glass tube, and it is no longer necessary to process the flange to withstand the punching pressure on the glass tube, which simplifies the structure of the glass tube and eliminates the need for the glass tube during operation. It is placed vertically, so the length of the glass tube can be extended as required, and the manufacturing cost is reduced, which will be more conducive to expanding the scale of solar energy utilization.

另外，由于本发明的玻璃金属副过渡连接装置结构简单，制造容易，对其进行改型设计十分方便，因此也极容易在不增加任何附加成本的条件下，对真空集热管进行改型设计，可以满足不同的使用需求。 In addition, since the glass-metal secondary transition connecting device of the present invention has a simple structure and is easy to manufacture, it is very convenient to retrofit the design. Therefore, it is extremely easy to retrofit the vacuum heat collecting tube without adding any additional cost. Can meet different usage needs.

本发明中，在真空集热管的制造中的金属与玻璃管间的封接难题，转换成金属连接件与玻璃连接件之间的封接，因此由封接造成的废品损失被大大地降低了。附图简要说明 In the present invention, the sealing problem between the metal and the glass tube in the manufacture of the vacuum heat collecting tube is converted into the sealing between the metal connector and the glass connector, so the loss of waste caused by the sealing is greatly reduced. .

实施本发明的方式 Mode of Carrying Out the Invention

实施例 1 Example 1

请参见图 1 至图 3所示，本发明的玻璃金属副过渡连接装置，由玻璃连接件 1和金属连接件 1封接而成，该玻璃连接件 1至少设有一个的通孔 11 , 该金属连接件 2设有相应的通孔 21 , 该玻璃连接件 1与金属连接件 2封接在一起；玻璃连接件 1设有可与玻璃管 4封接的连接端，金属连接件 1设有可于金属吸热体 5封接的连接端。为使金属连接件 2 与玻璃连接件 1 的封接面上漏率达到真空集热管的使用需求，沿玻璃连接件 1 的通孔 11 的周边设有一平面 12 , 金属连接件 2相对应地设有平面 22，当玻璃连接件 1和金属连接件 2沿该通孔 11和 21的周边平面处封接后，在本发明的玻璃金属副过渡连接装置上构成一个可供金属吸热体 5 穿入的通孔。 1 to 3, the glass-metal secondary transition connection device of the present invention is formed by sealing the glass connection member 1 and the metal connection member 1. The glass connection member 1 is provided with at least one through hole 11. The metal connecting piece 2 is provided with a corresponding through hole 21, and the glass connecting piece 1 and the metal connecting piece 2 are sealed together; the glass connecting piece 1 is provided with a connection end that can be sealed with the glass tube 4, and the metal connecting piece 1 is provided with The connection end can be sealed at the metal heat sink 5. In order to make the leakage rate on the sealing surface of the metal connector 2 and the glass connector 1 meet the requirements of the vacuum heat collecting tube, a plane 12 is provided along the periphery of the through hole 11 of the glass connector 1, and the metal connector 2 is correspondingly arranged. There is a plane 22, and when the glass connecting member 1 and the metal connecting member 2 are sealed along the peripheral planes of the through holes 11 and 21, a glass-metal secondary transition connecting device of the present invention is formed to allow the metal heat sink 5 to pass through. Into the through hole.

本发明的玻璃金属副过渡连接装置中的玻璃连接件 1 的形状可根据玻璃管的截面形状设计，本实施例中，金属连接件 2的金属连接端可以为沿通孔 21周边的管状颈部 23 , 其与玻璃连接件 1封接的封接端可以为圆盘体 24 , 吸热体 5 的伸出端可沿周边悍封于该管状颈部 24。具有一定长度的管状颈部 24 有利于吸热体 5的定位并形成对吸热体 5稳定的支撑。玻璃连接件 1的玻璃连接端为沿周边向下的凸缘 13，可由该玻璃连接件 1的凸缘 13与玻璃管 4端面封接。 The shape of the glass connector 1 in the glass-metal secondary transition connection device of the present invention may be designed according to the cross-sectional shape of the glass tube. In this embodiment, the metal connection end of the metal connector 2 may be a tubular neck along the periphery of the through hole 21. 23. The sealing end sealed with the glass connecting member 1 may be a disc body 24, and the protruding end of the heat absorbing body 5 may be tightly sealed to the tubular neck 24 along the periphery. The tubular neck 24 having a certain length facilitates the positioning of the heat absorbing body 5 and forms a stable support for the heat absorbing body 5. The glass connection end of the glass connection member 1 is a flange 13 which is downward along the periphery, and the flange 13 of the glass connection member 1 and the end face of the glass tube 4 can be sealed.

如图 1所示，在本实施例中，金属连接件 2与玻璃连接件 1可采用常规的热压封接的方法进行封接，所述的玻璃连接件 1的平面 12与金属连接件 2的平面 22通过焊料 3热压封在一起。由于玻璃连接件 1基本呈体积较小的盘状体，这种结构加热方便，同时具有极好的承压能力，因此对热压封的工艺要求相对现有技术中的对玻璃管的热压封的工艺要求低得多。 As shown in FIG. 1, in this embodiment, the metal connecting member 2 and the glass connecting member 1 can be sealed by a conventional thermocompression sealing method. The plane 12 of the glass connecting member 1 and the metal connecting member 2 are sealed. The flat surfaces 22 are heat-sealed together by solder 3. Since the glass connector 1 is basically a disk-shaped body with a relatively small volume, this structure is convenient for heating and has excellent pressure-bearing capacity. Therefore, the process requirements for heat-sealing are relatively higher than those for glass pipes in the prior art. The process requirements for sealing are much lower.

本实施例还可实施为如图 2所示的方式，所述的玻璃连接件 1的平面 12设于玻璃连接件 1的下端面，玻璃连接件 1的通孔 11的直径应大于金属连接件 2 管状颈部 23的外径，该管状颈部 23穿设于通孔 11内，玻璃连接件 1的平面 12 与金属连接件 2的平面 22通过焊料 3热压封在一起，从而完成对玻璃连接件 1 与金属连接件 1的封接。 This embodiment can also be implemented as shown in FIG. 2. The plane 12 of the glass connector 1 is provided on the lower end surface of the glass connector 1. The diameter of the through hole 11 of the glass connector 1 should be larger than that of the metal connector. 2 The outer diameter of the tubular neck 23, which passes through the through hole 11, the plane 12 of the glass connector 1 and the plane 22 of the metal connector 2 are heat-sealed together by solder 3, thereby completing the glass Sealing of the connecting member 1 and the metal connecting member 1.

如图 3所示，本实施例中，金属连接件 2与玻璃连接件 1还可采用常规的火焰熔接的方法进行封接。本实施方式中，玻璃连接件 1的通孔 11的直径较大，可将金属连接件 2的圆盘体 24穿入该通孔 11内 , 并沿该圆盘体 24的周边火焰熔接于所述的通孔 11内。 As shown in FIG. 3, in this embodiment, the metal connecting member 2 and the glass connecting member 1 can also be sealed by a conventional flame welding method. In this embodiment, the diameter of the through hole 11 of the glass connector 1 is large. The disc body 24 of the metal connector 2 can be inserted into the through hole 11 and flame-welded along the periphery of the disc body 24 to the内内的通孔 11。 Inside the through hole 11.

本发明的玻璃金属副过渡连接装置主要应用于太阳能真空集热管的制造，当其连接于玻璃管 4开口端时，由玻璃连接件 1的凸缘 13作为玻璃连接端与玻璃管 4 进行封接。本发明还可采用上述溶接方法进行实现，但由于玻璃连接件 1 的体积远远小于玻璃管 4 的体积，使得其熔接后对玻璃连接件 1 的退火也相对地容易。而玻璃管 4 内的吸热体 5的金属管则由本装置的金属连接件 2的通孔 21伸出，并与之封接。 The glass-metal secondary transition connection device of the present invention is mainly applied to the manufacture of a solar vacuum heat collecting tube. When it is connected to the open end of the glass tube 4, the flange 13 of the glass connector 1 is used as the glass connection end to seal the glass tube 4. . The present invention can also be implemented by using the above-mentioned melting method, but since the volume of the glass connection piece 1 is much smaller than the volume of the glass tube 4, the annealing of the glass connection piece 1 after welding is also similar. Easy to the ground. The metal tube of the heat absorbing body 5 in the glass tube 4 protrudes from the through hole 21 of the metal connector 2 of the device and is sealed to it.
