Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a temperature regulating device of external nitrogen cylinder, includes nitrogen cylinder 1, the outer wall of nitrogen cylinder 1 is equipped with first hot exchange pipe 2 and temperature control probe 9, and first hot exchange pipe 2 is winding state and sets up outside nitrogen cylinder 1. An expansion valve 10 and a cold and hot gas generating device 4 are communicated between two side ports of the first heat exchange tube 2 through a circulating tube 3, and the temperature control of the outer wall of the nitrogen cylinder 1 is realized through the gas-liquid conversion of a refrigerant. The cold and hot gas generating device 4 is electrically connected with the controller 5 and the storage battery 6, power is supplied through the storage battery 6, meanwhile, the controller 5 is electrically connected with the temperature control probe 9, and the controller 5 controls the cold and hot gas generating device 4 according to the measured temperature information, so that refrigeration or heating is realized. The storage battery 6 is electrically connected with the charging device and supplies power to the whole device.
The cold and hot gas generating device 4 comprises a liquid storage tank 4-1, a second heat exchange pipe 4-2 and a compressor 4-3, wherein the liquid storage tank 4-1, the second heat exchange pipe 4-2, the compressor 4-3, the first heat exchange pipe 2 and the expansion valve 10 are communicated in sequence. While the controller 5 controls the compressor 4-3 to perform a refrigerant cycle and heat exchange of the second heat exchanging tube 4-2.
The charging device comprises a solar cell panel 7, and the solar cell panel 7 is arranged at the output end of the rotating motor 8; the solar cell panel 7 is provided with a photosensitive resistance element which is electrically connected with an external controller, and the external controller is electrically connected with the rotating motor 8. The circuit diagram of the photoresistor element is shown in fig. 3, the photoresistor element can track the direct sunlight position to adjust the position of the solar cell panel 7, so that the solar cell panel 7 is always positioned in the maximum sunlight irradiation range, and the photoelectric conversion capability of the solar cell panel 7 is improved. This section is an application of the prior art, which is currently installed in a large number of solar power plants and is described in a number of published patents, such as CN211791401U, CN109995316B and CN 203012517U.
The nitrogen cylinder 1 and the first heat exchange tube 2 are externally provided with heat exchange bags, and the heat exchange bags are wrapped outside the nitrogen cylinder 1 and the first heat exchange tube 2. The heat exchange bag is made of silicon rubber, the heat conductivity coefficient of the heat exchange bag is far smaller than that of the cylinder wall (iron alloy), and the heat exchange effect on the nitrogen cylinder 1 is guaranteed.
The working principle is as follows:
when the refrigeration works, when the temperature control probe 9 connected with the controller 5 reaches a preset judgment value, the compressor 4-3 of the cold and hot gas generating device 4 is controlled to rotate the liquid refrigerant in the cold and hot gas generating device 4 in the anticlockwise direction, and the liquid refrigerant enters the first heat exchange tube 2 after passing through the expansion valve 10 from the liquid storage tank 4-1 and being vaporized through the pipeline. The vaporized refrigerant absorbs heat from the surrounding environment in the first heat exchange tube 2, because the thermal conductivity of the silicone rubber material is much smaller than that of the cylinder wall (iron alloy). Therefore, the first heat exchange pipe 2 mainly absorbs the heat of the nitrogen cylinder 1 and plays a role in cooling the nitrogen cylinder 1. The gaseous refrigerant flows back to the compressor 4-3 of the hot and cold gas generating device 4 through the pipeline after passing through the first heat exchange tube 2, the density of the gaseous refrigerant is increased after passing through the compressor 4-3, the gaseous refrigerant flows to the second heat exchange tube 4-2 through the pipeline to radiate heat to the atmosphere, then the gaseous refrigerant is liquefied and flows back to the liquid storage tank 4-1 through the pipeline, and the cycle is carried out in the process after the refrigerant is liquefied. When the controller 5 sends out a stop signal, the compressor 4.3 of the hot and cold air generating device 4 stops working.
The expansion valve 10 is not a one-way valve. In practice the gas-liquid transition of the refrigerant is a gradual process which does not necessarily occur actually through the expansion valve 10, but may (mostly) occur after a delay inside the first heat exchanger tube 2. The high-pressure liquid refrigerant inside the counterclockwise liquid reservoir 4-1 is vaporized by the obstruction of the expansion valve 10 or changed into a low-pressure liquid refrigerant. The low-pressure refrigerant is gradually vaporized in the first heat exchange tube 2 to become low-pressure gaseous refrigerant, the low-pressure gaseous refrigerant is changed into high-pressure gaseous refrigerant through the compressor 4-3, the high-pressure gaseous refrigerant passes through the second heat exchange tube 4-2 and is gradually liquefied in the middle of the second heat exchange tube 4-2 to become high-pressure liquid refrigerant, and the high-pressure liquid refrigerant flows back to the liquid storage tank 4-1.
When the controller 5 sends a heating signal, the whole work flow is opposite to the cooling. The compressor 4-3 of the hot and cold gas generating device 4 works in a forward direction, the gaseous refrigerant in the hot and cold gas generating device 4 flows into the first heat exchange tube 2 from the compressor 4-3 through the pipeline in a clockwise direction, and the gaseous refrigerant is liquefied and flows out of the first heat exchange tube 2 at the pipeline outlet on the other side of the first heat exchange tube 2 due to the obstruction of the expansion valve 10. Releasing heat to heat the cylinder. The refrigerant is liquefied after passing through the expansion valve 10, continuously flows back to the liquid storage tank 4-1 of the cold and hot gas generation device 4 through the pipeline clockwise through the pipeline, and the liquid refrigerant passes through the pipeline to the second heat exchange pipe 4-2 to absorb heat, is vaporized, enters the compressor 4-3 and circulates again. The compressor 4-3 of the hot and cold air generating means 4 stops operating when the controller 5 gives a stop signal.
