Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0020] Please refer to Figures 1-5The utility model provides a technical scheme: an energy storage plate with phase change material, including first panel 1, second panel 2 and support framework 3, and the upside and downside of support framework 3 are fixedly connected with first panel 1 and second panel 2 respectively, a plurality of storage tubes 4 are fixedly installed in the inside of support framework 3, and the upside and downside of energy storage plate are all provided with flow guide recess 5, and first sealing strip 6 and second sealing strip 7 are fixedly installed on the upside and downside of energy storage plate respectively, and first sealing strip 6 and second sealing strip 7 are sealed and cover the mouth of upside and downside flow guide recess 5 respectively, and upside and downside flow guide recess 5 are communicated through storage tube 4.
[0021] Wherein, the inside of first sealing strip 6 and second sealing strip 7 is fixedly installed with a plurality of partition blocks 8, the partition block 8 can be inserted into the flow guide recess 5, so that the upside and downside flow guide recess 5 are divided into a plurality of communicating chambers by the partition block 8.
[0022] The two sides of energy storage plate are fixedly installed with third sealing strip 9 and fourth sealing strip 10 respectively, the surface of third sealing strip 9 is fixedly installed with input pipe 11, the surface of fourth sealing strip 10 is fixedly installed with output pipe 12, and input pipe 11 and output pipe 12 are communicated with flow guide recess 5.
[0023] A plurality of storage tubes 4 are arranged in parallel, and a plurality of storage tubes 4 are communicated in S type series through the above-mentioned communicating chambers, as shown by the dotted line, Figure 4 The phase change material is injected from input pipe 11, sequentially enters each storage tube 4, and then overflows from output pipe 12, to realize the charging of phase change material to storage tube 4.
[0024] In addition, support framework 3 is composed of a plurality of parallel slats, a plurality of storage cavities 13 are formed between the plurality of parallel slats, a sunken groove 14 is formed in the end of the slat, and the plurality of storage cavities 13 are communicated through the sunken groove 14.
[0025] The surface of storage tube 4 and the inner surface of first panel 1 and second panel 2 are all reserved with flow gap 15, the storage cavities 13 between adjacent slats are communicated to form a storage cavity 13 through the energy storage plate left and right through flow gap 15, the third sealing strip 9 is disassembled, and the phase change material is conveniently charged to each storage cavity 13, as shown by the dotted line. Figure 5
[0026] Working principle: For example, phase change paraffin wax is selected as the phase change material for filling. This phase change material can exchange energy with the external environment (absorb heat from the external environment or release heat to the external environment), thereby achieving the purpose of controlling the ambient temperature and utilizing energy. That is, the phase change material absorbs heat and undergoes a phase change (melting and heat storage process) when the temperature is higher than the phase change point, so that its temperature no longer rises or rises only slightly. When the temperature drops and falls below the phase change point, a reverse phase change occurs (solidification and heat release process). The phase change material can restore its original phase structure and perform heat release work. This phase change material will not change shape due to the morphological change of the phase change paraffin wax. The energy storage board with phase change material can be used as a building insulation layer.
[0027] In this embodiment, the first sealing strip 6, the second sealing strip 7, the third sealing strip 9, and the fourth sealing strip 10 are fixedly connected to the support frame 3 by screws 16. The inner sides of the first sealing strip 6, the second sealing strip 7, the third sealing strip 9, and the fourth sealing strip 10 are coated with sealant and are respectively glued and fixed to the four sides of the first panel 1 and the second panel 2 by the sealant. Since the first sealing strip 6, the second sealing strip 7, the third sealing strip 9, and the fourth sealing strip 10 can all be disassembled, the sealing strips at appropriate positions are selected for disassembly, and then the length and width dimensions of the energy storage plate are cut to meet the requirements. Then, the sealing strips are reassembled and sealed to make the energy storage plate cut.
[0028] This energy storage plate with phase change material has the function of storing and releasing energy by setting parallel storage tubes 4 in the support frame 3. After the length and width of the energy storage plate are cut off, part of the storage tubes 4 are cut off. Then, the flow guide groove 5 and the sink groove 14 are opened. The remaining storage tubes 4 can still be connected in series in an S-shape by reinstalling the first sealing strip 6, the second sealing strip 7, the third sealing strip 9 or the fourth sealing strip 10. This not only makes it convenient to fill the storage tubes 4 with phase change material, but also makes it convenient to cut the size of the energy storage plate, making it more convenient to use.
[0029] It should be noted that the energy storage plate with phase change material has a storage pipe 4 and a storage cavity 13 inside, and phase change material can be filled into the storage pipe 4 and the storage cavity 13 respectively to manufacture two different styles of energy storage plates.
[0030] Two methods for filling phase change materials: The first method involves filling the phase change material into a non-cut energy storage plate, such as... Figure 5 As shown by the dotted line, loosening the third sealing strip 9 allows the storage chamber 13 to be filled with phase change material. The internal air is discharged from the gap of the third sealing strip 9. If the phase change material overflows from the gap of the third sealing strip 9, it proves that the storage chamber 13 is full. Then it is sealed. The storage chamber 13 is filled with phase change material and can be used as a non-cut energy storage plate.
[0031] The second, the phase change material of the cutting energy storage plate is filled, when the energy storage plate needs to be cut during the filling process, the energy storage plate is cut, and after the size is determined, the phase change material is filled into the energy storage plate as shown by the dashed line in the middle. Figure 4 The phase change material enters each storage tube 4 in turn, and then overflows from the output pipe 12. After cutting, the phase change material in the storage tube 4 is filled, which can well prevent material shortage. By setting the above two types of energy storage plates, the internal structures of the two types of energy storage plates are completely the same, only the position of filling the phase change material is improved, the problems of complex process and long cycle of custom production are solved, so that the corresponding style of the energy storage plate is selected according to different application scenes, and the energy storage plate has better universality.
[0032] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
