Description

Technical Field

[0001] This utility model specifically relates to a temperature control system. Background Technology

[0002] In the field of industrial process temperature control, rapid cooling of reaction vessels, fermenters, or gas delivery pipelines is often required to ensure process stability and product consistency. Traditional methods often employ compressor refrigeration units or liquid nitrogen spray systems: the former has a complex structure, long start-up time, and requires multiple components such as evaporators, condensers, and expansion valves, resulting in high costs for construction and maintenance; the latter, while offering fast cooling rates, consumes large amounts of liquid nitrogen, leading to expensive operating costs, and also presents challenges related to low-temperature embrittlement and safe storage. Utility Model Content

[0003] The purpose of this invention is to provide a temperature control system to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a temperature control system, comprising: High-pressure air source; A vortex generator in fluid communication with the high-pressure air source, the vortex generator being configured to separate high-pressure air into a cold air stream and a hot air stream, a front section of a cold air stream tube in fluid communication with the cold air stream outlet of the vortex generator, a rear section of a cold air stream tube in series with the front section of the cold air stream tube, and an oil tank in fluid communication with the outlet of the rear section of the cold air stream tube, the oil tank being used to receive the cold air stream and perform heat exchange. A heat return pipe in fluid communication with the oil tank outlet and a heat exchanger in fluid communication with the outlet of the heat return pipe, wherein the heat exchanger is used to cool the fluid in the heat return pipe.

[0005] Preferably, it also includes a jacket in fluid communication with the cold side outlet of the heat exchanger, the jacket being used to cover the temperature-controlled pipeline and transfer cooling capacity.

[0006] Preferably, it also includes a return oil pipe that is in fluid communication with the return oil port of the jacket, the return oil pipe sending the heat-exchanged fluid back to the oil tank to form a closed loop.

[0007] Preferably, the jacket has a sampling port on its outer side for detecting the temperature of the fluid inside the tank.

[0008] Preferably, the jacket is an annular jacket, and its internal flow channel is in contact with the outer wall of the temperature-controlled pipeline.

[0009] Preferably, a circulation pump is installed on the return oil pipe.

[0010] Preferably, the return oil pipe is connected to an oil drain port via an independent pipe.

[0011] The technical effects and advantages of this utility model are as follows: The temperature control system consists of four functional sections connected in series: a vortex generator, an oil tank, a heat exchanger, and a jacket. It eliminates the need for complex components such as traditional refrigeration units, expansion valves, condensers, and evaporators, and also eliminates the need for additional refrigerant. High-pressure air can instantly generate a cold airflow in the vortex generator and directly inject it into the oil tank to mix and exchange heat with the heat transfer oil. The front and rear sections of the cold flow pipe adopt a single straight-through pipeline, which enables the entire cycle to quickly reach the target temperature and significantly shortens the production waiting time.

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0015] refer to Figure 1 As shown, the system includes a high-pressure air source 1; a silencer fluidly connected to the high-pressure air source 1, configured to reduce aerodynamic noise generated by the high-pressure air source 1; a vortex generator 2 fluidly connected to the high-pressure air source 1, configured to separate high-pressure air into a cold air stream and a hot air stream, with the hot air stream outlet of the vortex generator 2 also connected to a silencer; a cold air stream front section 3 fluidly connected to the cold air stream outlet of the vortex generator 2; a cold air stream rear section 4 connected in series with the cold air stream front section 3; an oil tank 5 fluidly connected to the outlet of the cold air stream rear section 4, the oil tank 5 being used to receive the cold air stream and perform heat exchange; a hot air return pipe 6 fluidly connected to the oil outlet of the oil tank 5; and a heat exchanger 7 fluidly connected to the outlet of the hot air return pipe 6. The heat exchanger 7 is used to cool the fluid in the heat return pipe 6. It consists of four functional sections connected in series: vortex generator 2, oil tank 5, heat exchanger 7, and jacket 8. It eliminates the need for complex components such as traditional refrigeration units, expansion valves, condensers, and evaporators, and also eliminates the need for additional refrigerant. High-pressure air can instantly generate a cold airflow in the vortex generator 2 and directly inject it into the oil tank 5 to mix and exchange heat intensely with the heat transfer oil. The front section 3 and the rear section of the cold flow pipe adopt a single straight-through pipeline, which allows the entire cycle to quickly reach the target temperature. The overall pipeline structure is simple, increases control accuracy, and reduces cooling time.

[0016] refer to Figure 1As shown, it also includes a jacket 8 that is fluidly connected to the cold-side outlet of the heat exchanger 7. The jacket 8 is used to cover the temperature-controlled pipeline and transfer cold energy. The outer wall of the jacket 8 is wrapped with a thick aerogel insulation layer. A quick-connect temperature sensor is installed inside the jacket 8 to provide real-time feedback on the heat transfer oil temperature and link it with the high-pressure air intake proportional valve to achieve closed-loop temperature control accuracy. Electric heating is also provided so that the heat transfer oil is first heated to the set temperature when the machine is started or in low-temperature conditions, and then finely lowered by a cold airflow; this also prevents the heat transfer oil from becoming too cold and its viscosity from increasing due to long-term shutdown. It also includes an oil return pipe 9 that is fluidly connected to the oil return port of the jacket 8. The oil return pipe 9 sends the heat-exchanged fluid back to the oil tank 5, forming a closed loop, allowing the heat transfer oil to be reused repeatedly, further reducing operating costs. A sampling port 10 is provided on the outside of the jacket 8 for detecting the fluid temperature in the oil tank 5, which can quickly determine the actual oil temperature, making debugging and calibration more convenient and improving safety. The jacket 8 is an annular jacket 8, whose internal flow channel contacts the outer wall of the temperature-controlled pipeline, reducing the circumferential temperature difference, eliminating local hot spots, and improving product consistency; at the same time, it reduces installation space and makes the shape more compact. A circulation pump 11 is installed on the oil return pipe 9, solving the problem of insufficient flow rate under extreme operating conditions and making the system more adaptable. An oil drain port 12 is connected to the oil return pipe 9 via an independent pipe, allowing oil drainage to be completed without disassembling the main circuit during oil changes, cleaning, and maintenance, shortening downtime.
