Description

Technical Field

[0001] This utility model relates to the field of thermoacoustic technology, and in particular to a thermoacoustic cooling device using solar energy. Background Technology

[0002] Thermoacoustic refrigeration devices offer advantages such as long service life, reliable operational stability, and the ability to directly utilize heat sources as driving forces, enabling them to utilize solar energy, waste heat, and other energy sources for refrigeration. A thermoacoustic refrigeration device comprises a thermoacoustic engine and a thermoacoustic refrigerator, both structurally identical. Both the thermoacoustic engine and the thermoacoustic refrigerator convert energy through regenerators. Specifically, the thermoacoustic engine converts thermal energy into sound wave energy, while the thermoacoustic refrigerator converts sound wave energy into thermal energy (for external cooling).

[0003] An existing patent application (201610157190.7) describes a self-cleaning solar thermoacoustic cooling device for desert areas. This device includes a second glass tube, the top of which is connected to a resonant tube. A second thermoacoustic stack is located inside the top of the second glass tube, while a first thermoacoustic stack is located at the top of the resonant tube, within the top-sealed first glass tube. A solar concentrator is fixed outside the second glass tube, positioning the lower part of the second thermoacoustic stack at the focal point of the concentrator, making the lower part of the second thermoacoustic stack a solar heating point. The device utilizes the upward expansion of heated gas, with the first and second thermoacoustic stacks assisting in oscillating and compressing the gas, achieving a reciprocating heat circulation. A heat exchange tube is located at the cold end, outside the top of the first glass tube, to obtain circulating cooling water. While this device can achieve solar thermoacoustic cooling, it is overly reliant on sunlight; cooling ceases immediately once sunlight disappears. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a solar-powered thermoacoustic cooling device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A solar-powered thermoacoustic cooling device includes a solar panel support, a set of concentrators, a set of collector tubes, a support frame, and a thermoacoustic cooling system. A storage tank is provided on one side of the first support, and a first infusion pipe is connected to one side of the storage tank. The first infusion pipe is connected to a heating pipe, which passes through the set of collector tubes in sequence. The outlet of the heating pipe is connected to the storage tank, and the first infusion pipe is connected to the thermoacoustic cooling system through a second infusion pipe.

[0007] Preferably, a circulation pump is provided inside the storage tank, and the circulation pump is connected to the first infusion pipe.

[0008] Preferably, the thermoacoustic refrigeration system includes two thermoacoustic engines, two thermoacoustic refrigerators, and a thermal buffer tube. Each thermoacoustic engine includes a regenerator, a hot-end heat exchanger, a cold-end heat exchanger, and two docking ports. One end of the heat exchange channel of each hot-end heat exchanger is connected to a return pipe, which is connected to the storage tank. The other end of the heat exchange channel is connected to a fourth infusion pipe, and both fourth infusion pipes are connected to the second infusion pipe.

[0009] Preferably, a solenoid valve is connected to the second infusion tube.

[0010] Preferably, the solar panel bracket includes a front bracket, a support frame hinged to the upper side of the front bracket, a set of solar concentrators connected to the upper side of the support frame, and the support frame is bolted to the rear bracket.

[0011] The advantages of this utility model are as follows: The thermoacoustic cooling device using solar energy provided by this utility model concentrates sunlight through a concentrator to irradiate the heat collection tube, which then heats the liquid inside the heating tube. The heated liquid is stored and kept warm in a storage tank. When the thermoacoustic cooling device is ready to cool, a solenoid valve is activated, allowing the heated liquid to enter the thermoacoustic device as a heat source, thus enabling the thermoacoustic cooling device to cool. Even without sunlight, it can rely on the hot oil kept warm in the storage tank for a long period of time to provide cooling. Attached Figure Description

[0015] like Figure 1 As shown, the present invention provides a solar-powered thermoacoustic cooling device, including a solar support 1, a set of concentrating plates 2, a set of heat collection tubes 3, a support frame 4, and a thermoacoustic cooling system 5. The concentrating plates 2 concentrate sunlight to irradiate the heat collection tubes 3, while the thermoacoustic cooling system 5 is an existing structure. For the specific structure, please refer to the regenerator, thermoacoustic core element and loop traveling wave thermoacoustic cooling system in application number CN202411527515.7.

[0016] The thermoacoustic refrigeration system includes two thermoacoustic motors, two thermoacoustic refrigerators, and a thermal buffer tube. Each thermoacoustic motor includes a regenerator, a hot-end heat exchanger, a cold-end heat exchanger, and two docking ports. Each hot-end heat exchanger is equipped with a heat exchange channel. One end of the heat exchange channel of each hot-end heat exchanger is connected to a return pipe 10. The two return pipes 10 are connected to the storage tank 6.

[0017] The solar panel bracket 1 includes a front bracket 1.1, with a support frame 1.2 hinged to the upper side of the front bracket 1.1. The mounting frame 1.2 is inclined, and a set of concentrators 2 are connected to the upper side of the mounting frame 1.2. The mounting frame 1.2 is bolted to a rear bracket 1.3, which is a U-shaped frame. Each of the two vertical rods of the rear bracket 1.3 has a set of through holes, and each of the two side walls of the mounting frame 1.2 has threaded blind holes. Bolts pass through the corresponding through holes, and the bolt threads connect to the threaded blind holes, thereby connecting and fixing the mounting frame 1.2 and the rear bracket 1.3. The angle can be adjusted by rotating the mounting frame 1.2, so that the concentrators 2 can better receive sunlight.

[0018] Storage tank 6 is located on one side of support frame 1. Storage tank 6 is a commercially available tank with heat preservation function. The heated liquid is kept warm by storage tank 6. A first infusion pipe 7 is connected to one side of storage tank 6. A circulation pump is installed in storage tank 6. The circulation pump is connected to the first infusion pipe 7. The first infusion pipe 7 is connected to a heating pipe 8. The heating pipe 8 passes through a set of heat collection pipes 3 in sequence. The liquid in the heating pipe 8 is heated by the heating pipes 3. The heating pipe 8 is connected to a third infusion pipe 12. The third infusion pipe 12 is connected to storage tank 6. The circulation pump draws liquid from storage tank 6 into the first infusion pipe 7, and then through the heating pipe 8 and the third infusion pipe 12, and finally returns to storage tank 6, forming a liquid flow circulation. In this embodiment, storage tank 6 stores oil, and the first infusion pipe 7 and the third infusion pipe 12 are both high-temperature resistant metal hoses.

[0019] Furthermore, the first infusion pipe 7 is connected to the thermoacoustic refrigeration system 5 through the second infusion pipe 9, that is, the second infusion pipe 9 is connected to two fourth infusion pipes 11, and each fourth infusion pipe 11 is connected to the corresponding heat exchange channel, so that the hot oil in the storage tank 6 is used as a heat source to be input into the heat exchange channel of the hot end heat exchanger.

[0020] Furthermore, a solenoid valve 9.1 is connected to the second infusion pipe 9. The solenoid valve 9.1 controls the opening and closing of the second infusion pipe 9. When the thermoacoustic refrigeration system 5 is not running, the solenoid valve 9.1 is closed to prevent hot oil from entering the second infusion pipe 9. When the thermoacoustic refrigeration system 5 is running, the solenoid valve 9.1 is opened, allowing the hot oil to pass through the second infusion pipe 9, the third infusion pipe 11, the hot end heat exchanger, and the return pipe 10 in sequence, and finally return to the storage tank 6. The hot oil circulates in the first infusion pipe 7, the heating pipe 8, and the storage tank 6. The oil in the heating pipe 8 is heated by the heat collection pipe 3. After being heated by the solar energy for a period of time, the oil has a certain temperature. The storage tank 6 has a heat preservation function, which can maintain the temperature of the hot oil for a long time even at night when there is no sunlight. This allows the thermoacoustic refrigeration system 5 to work for a long time even without sunlight. In addition, the thermoacoustic refrigeration system 5 can also be used to make ice. The ice blocks can be placed indoors at night when there is no sun to cool the room.
