Description
Technical Field
[0001] This utility model relates to the field of heat storage module technology, and in particular to a low-temperature phase change heat storage module for solar greenhouses. Background Technology
[0002] With the increasing market demand for seedlings, the winter seedling market is growing. Winter-warm greenhouses are gradually showing their advantages of low cost and low energy consumption. However, conventional winter-warm greenhouses have a lot of earthen walls on both sides and the back, which occupy a lot of land. Therefore, steel-framed winter-warm greenhouses have emerged because they occupy less land and are easy to install. However, the new steel-framed winter-warm greenhouses do not have earthen walls to store heat, which leads to a drop in temperature inside the greenhouse at night in winter, affecting production.
[0003] Existing technology involves installing hot water storage bags on the back wall, but the limited volume of these bags means the heat they can store cannot meet the greenhouse's needs; installation is complex, maintenance costs are high, and disassembly is inconvenient. Utility Model Content

[0025] The following is in conjunction with the appendix Figures 1-5 The present invention will be further described below.
[0026] In order to solve the problems existing in the background technology, this application proposes the following technical solution: a low temperature phase change heat storage module for solar greenhouses.
[0027] The specific technical solution includes a heat storage shell assembly 1 and a phase change material 2. The heat storage shell assembly 1 includes a left mounting shell 101, a connecting plate 102, and a right mounting shell 103. The left mounting shell 101, the connecting plate 102, and the right mounting shell 103 are installed sequentially. Both the left mounting shell 101 and the right mounting shell 103 have cavities, and the phase change material 2 is filled in the cavities. The phase change material 2 is a phase change paraffin material with a phase change temperature of 18°C. The surfaces of both the left mounting shell 101 and the right mounting shell 103 are coated with a heat-absorbing coating. Coating 3: During the day, when sunlight shines on the greenhouse, the heat-absorbing coating 3 on the surface of the module absorbs sunlight and converts light energy into heat energy, which is stored in the phase change material 2. After a large number of experiments, a phase change paraffin material with a phase change temperature of 18℃ was selected, which is beneficial for absorbing and storing heat at low temperatures. At night, the phase change material 2 releases heat stably, which is also beneficial for absorbing excessively high temperatures in the greenhouse. The phase change heat storage capacity of a unit mass of 18℃ phase change paraffin material is more than 40 times that of water heat storage, thus greatly improving the heat storage capacity.
[0028] Furthermore, a socket protrusion 4 is provided on one side of the left mounting shell 101, and a socket slot 5 corresponding to the socket protrusion 4 is provided on one side of the right mounting shell 103. Multiple sets of heat storage modules can be easily connected and used through the socket protrusion 4 on the left mounting shell 101 and the socket slot 5 on the right mounting shell 103.
[0029] In specific implementations, such as Figure 2 and Figure 3As shown, the connecting plate 102 is provided with a plurality of mounting components 6 for mounting the heat storage shell assembly 1 to the shed pole. The mounting component 6 includes a mounting cylinder 601 and a mounting screw 602. The connecting plate 102 is provided with a plurality of mounting grooves 7. The mounting cylinder 601 is fixedly installed in the mounting grooves 7. The mounting cylinder 601 is provided with a threaded groove. The mounting screw 602 is engaged in the threaded groove. The mounting screw 602 can facilitate the connection between the connecting plate 102 and the shed pole, thus facilitating the installation of the heat storage module.
[0030] Furthermore, both sides of the bottom of the mounting screw 602 are provided with limiting components 8 for preventing detachment. The limiting components 8 include a limiting block 801 and a mounting spring 802. Grooves 9 are provided on both sides of the mounting screw 602. The limiting block 801 is installed on the inner wall of the groove 9 by the mounting spring 802. In the uninstalled state, the limiting block 801 squeezes the mounting spring 802 and retracts into the mounting cylinder 601. The shed rod should have a slot corresponding to the mounting groove 7. The mounting cylinder 601 is placed above the slot. Then the mounting screw 602 is screwed down. The mounting screw 602 moves down and enters the slot. After the limiting block 801 moves below the slot, it can pop out under the elastic force of the mounting spring 802. Then the mounting screw 602 is screwed up. Therefore, the heat storage component can be fixedly installed on the shed rod by the limiting block 801, and the installation is quick.
[0031] Furthermore, the edge of the limiting block 801 is provided with a contact slope 10. The contact slope 10 allows the mounting screw 602 to be turned upwards during disassembly. The contact slope 10 also allows the limiting block 801 to press the mounting spring 802 inwards along the edge of the slot and move into the groove 9. Once the limiting block 801 has completely moved back into the groove 9, the disassembly between the mounting component 6 and the bracket can be completed, thus facilitating assembly and disassembly.
[0032] Furthermore, both the left mounting shell 101 and the right mounting shell 103 are equipped with injection ports 11 that communicate with the accommodating cavity, through which the phase change material 2 can be conveniently injected or replenished into the accommodating cavity.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.

In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
