Description

Technical Field

[0001] This utility model relates to the field of heat pump application technology, and in particular to a photovoltaic heat pump. Background Technology

[0002] Against the backdrop of ever-increasing energy demand and increasingly stringent environmental requirements, traditional heat pump technology faces numerous challenges. This has spurred the research and innovation of photovoltaic heat pumps. Traditional heat pumps primarily rely on electricity to drive the compressor, making their energy source singular. In areas with tight power supplies or high electricity prices, operating costs increase significantly. Furthermore, with the continuous strengthening of global carbon emission restrictions, traditional heat pumps, due to their consumption of large amounts of conventional electricity, generate indirect carbon emissions during operation, putting pressure on the environment and failing to meet the needs of sustainable development. The heat absorption area of ​​traditional heat pump evaporators is relatively fixed, making it difficult to flexibly adjust according to environmental changes, thus limiting the energy efficiency of heat pumps under different operating conditions. For example, in winter when there is ample sunshine but low temperatures, traditional evaporators cannot fully utilize solar energy to improve heat absorption efficiency, resulting in limited overall heating performance of the heat pump. In terms of installation and maintenance, the installation of components in traditional heat pump systems often requires professional personnel to spend a lot of time on complex operations. When equipment malfunctions and requires repair or component replacement, the disassembly process is cumbersome, not only wasting manpower and resources but also causing prolonged equipment downtime, affecting normal user operation. Therefore, we have launched a new photovoltaic heat pump. Utility Model Content

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A photovoltaic heat pump includes an evaporator body 1 and a photovoltaic panel 2. Fixing devices 3 are provided at both the left and right ends of the photovoltaic panel 2, and a support frame 4 is provided between the two fixing devices 3. Two serpentine coils 5 are provided at the lower end of the photovoltaic panel 2, located between the photovoltaic panel 2 and the support frame 4. A first connecting pipe 6 is fixedly installed at the right end of the two serpentine coils 5, and a second connecting pipe 7 is provided at the left end of the two serpentine coils 5. A second connecting pipe 8 is fixedly installed on the outer surface of the second connecting pipe 7. A connecting mechanism 9 is fixedly installed on the right side of the outer surface of the first connecting pipe 6. A third connecting pipe 10 is provided at the right end of the evaporator body 1. Fixing seats 11 are fixedly installed at the front and rear right ends of the third connecting pipe 10 via embedded grooves. The inner walls of the two fixing seats 11 are provided with locking holes 12. The connecting mechanism 9 and the third connecting pipe 10 are positioned laterally.

[0025] In this embodiment, the fixing device 3 includes a U-shaped frame 30 and a corresponding seat 33. A corresponding block 31 is provided at the lower end of the U-shaped frame 30, and an insertion hole 32 is provided at the front end of the corresponding block 31. A corresponding groove 34 is provided at the rear of the upper end of the corresponding seat 33. A movable rod 35 is movably installed through the front end of the corresponding seat 33. A movable block 36 is movably installed through the inner groove at the front of the inner side of the corresponding seat 33. An insertion rod 37 is provided at the middle of the rear end of the movable block 36. A second spring 38 is movably sleeved on the outer surface of the movable rod 35. A pull handle 39 is provided at the front end of the movable rod 35. The rear end of the movable rod 35 is fixedly connected to the middle of the front end of the movable block 36. The front and rear parts of the outer surface of the second spring 38 are fixedly connected to the corresponding seat 33 and the movable block 36, respectively. The corresponding block 31 is movably engaged inside the corresponding groove 34. The insertion rod 37 is movably engaged inside the insertion hole 32 through the second spring 38 and the movable block 36.

[0026] With the above solution: when the U-shaped bracket 30 needs to be installed, align the corresponding block 31 with the corresponding slot 34 on the corresponding seat 33 and insert it. Before insertion, pull the movable rod 35 with the handle 39. The movable rod 35 drives the movable block 36 forward, compressing the second spring 38, so that the insertion rod 37 retracts from the front end of the corresponding seat 33. After the corresponding block 31 is fully inserted into the corresponding slot 34, release the handle 39. The second spring 38 rebounds and pushes the movable block 36 backward, so that the insertion rod 37 is inserted into the insertion hole 32 at the front end of the corresponding block 31, thereby fixing the U-shaped bracket 30 to the corresponding seat 33. When disassembling, pull the handle 39 again to remove the insertion rod 37 from the insertion hole 32, and the corresponding block 31 can be taken out from the corresponding slot 34.

[0027] In this embodiment, the connecting mechanism 9 includes a first connecting tube 90, which is U-shaped in shape. A connecting sleeve 91 is movably sleeved on the lower left side of the outer surface of the first connecting tube 90. A sealing gasket 92 is provided at the left end of the connecting sleeve 91. Fixing blocks 93 are provided at the front and rear left ends of the connecting sleeve 91. A driving block 94 is movably installed inside the two fixing blocks 93 through an inner groove. A first spring 95 is fixedly installed inside the two fixing blocks 93 through an inner groove. A locking block 96 is fixedly installed at the end of the two driving blocks 94 away from the first spring 95. The connecting sleeve 91 is movably locked to the right end of the third connecting tube 10 through the sealing gasket 92. The fixing block 93 is movably locked inside the fixing seat 11. The locking block 96 is movably locked inside the locking hole 12 through the first spring 95 and the driving block 94. The first connecting tube 90 extends to the right side of the interior of the third connecting tube 10.

[0028] The above scheme works as follows: When connecting the first connecting pipe 90 and the third connecting pipe 10, the sealing gasket 92 at the left end of the connecting sleeve 91 is aligned with the right end of the third connecting pipe 10, and the connecting sleeve 91 is pushed towards the third connecting pipe 10. At this time, the fixing block 93 will be inserted into the fixing seat 11. During the insertion process, the locking block 96 is squeezed by the inner wall of the fixing seat 11, which drives the driving block 94 to compress the first spring 95. When the fixing block 93 is fully inserted into the fixing seat 11 and the locking block 96 reaches the locking hole 12, the first spring 95 rebounds, pushing the driving block 94 to make the locking block 96 lock into the locking hole 12, thus realizing the connection between the first connecting pipe 90 and the third connecting pipe 10. At the same time, the sealing gasket 92 plays a sealing role. When disassembling, an external force is applied to the locking block 96 to make it overcome the elastic force of the first spring 95 and exit the locking hole 12, thus realizing the disassembly and separation of the first connecting pipe 90 and the third connecting pipe 10.

[0029] It should be noted that this utility model is a photovoltaic heat pump. During use, when installing the photovoltaic panel 2, by pulling the handle 39 of the fixing device 3, the insertion rod 37 is retracted, and the corresponding block 31 of the U-shaped frame 30 is inserted into the corresponding groove 34 of the corresponding seat 33. Releasing the handle 39, the insertion rod 37 is inserted into the insertion hole 32 under the action of the second spring 38, completing the fixing. Then, the left end of the connecting mechanism 9 is aligned with the right end of the first connecting pipe 90, and the sealing gasket 92 is aligned with the right end of the third connecting pipe 10. Then, the fixing block 93 is pushed into the fixing seat 11. The locking block 96 is compressed by the first spring 95. When it reaches the locking hole 12, the first spring 95 rebounds, causing the locking block 96 to engage, thus achieving the connection and sealing between the first connecting pipe 90 and the third connecting pipe 10. The photovoltaic panel 2 absorbs solar energy, and the fluorine in the serpentine coil 5 below it absorbs heat from the photovoltaic panel 2, raising its temperature. The heat is transferred through the first connecting pipe 6 and the second connecting pipe 7. The second connecting pipe 8 can be used for related fluid transport operations. The heated fluorine enters the evaporator body 1 through the connecting mechanism 9 and the third connecting pipe 10 of the evaporator body 1, increasing the heat absorption area of ​​the evaporator body 1 and raising the temperature of the fluorine, thereby improving the energy efficiency of the heat pump. When the photovoltaic panel 2 is disassembled, firstly, external force is applied to the locking block 96 to make it exit the locking hole 12, which can separate the first connecting pipe 90 from the third connecting pipe 10. Then, the pull handle 39 is pulled to make the insertion rod 37 exit from the insertion hole 32, so that the corresponding block 31 can be taken out from the corresponding slot 34, realizing the separation of the photovoltaic panel 2 from the support frame 4.
