Description

Technical Field

[0001] This utility model relates to the field of natural gas development equipment technology, and more specifically, to a non-electric thermosiphon self-circulating cooler. Background Technology

[0002] Currently, with the increasing emphasis on the development and utilization of natural gas as a green energy source, the release of production capacity from marginal wells and remote, low-yield wells that cannot be transported to the gas transmission network via pipelines is typically addressed through CNG tanker transport or liquefaction and loading of LNG into skid-mounted units for sale. However, skid-mounted LNG units have high energy consumption, typically exceeding 0.5 kW / m³, which is significantly higher than that of large-scale LNG plants. Especially during the high-temperature summer months, skid-mounted air-cooled LNG units struggle to reach normal production loads due to their high energy consumption, further increasing the unit's energy efficiency ratio. Therefore, developing a thermosiphon-type self-circulating cooler to cool the LNG refrigerant compressor, thereby achieving energy savings and ensuring the unit's production load under extreme conditions, is particularly important.

[0003] Furthermore, in modern industrial production and daily life, coolers, as key heat exchange devices, play a vital role in applications requiring heat transfer and temperature control. However, traditional coolers mostly rely on electrically driven components (such as fans and compressors) to achieve the circulation of the cooling medium and heat exchange. But in certain specific environments or application scenarios, the power supply may be unstable or unavailable, which limits the application of traditional coolers.

[0004] Meanwhile, with the increasing energy crisis and growing environmental awareness, energy conservation and consumption reduction have become important trends in industrial design and product development. Traditional electrically driven coolers have significant shortcomings in terms of energy consumption and may generate noise and emit harmful substances during operation, negatively impacting the environment. Therefore, developing a cooling solution that does not rely on electricity and is energy-efficient and environmentally friendly has an urgent practical need and broad market prospects.

[0007] Preferably, the oil pipe is fixed by a positioning plate, and the surface of the positioning plate is provided with several round holes.

[0008] Preferably, a baffle is installed on the upper part of the inside of the oil tank, and a heat dissipation vent is provided on the top of the oil tank.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This non-electric thermosiphon self-circulating cooler utilizes the thermosiphon principle to achieve natural circulation and heat exchange of the cooling medium, eliminating the need for electric drive. This reduces energy consumption and improves the reliability and applicability of the equipment, especially in situations where power supply is unstable or unavailable.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides an electric-free thermosiphon self-circulating cooler, such as... Figures 1-3As shown, the system includes a heat sink 1, with several oil pipes 2 vertically installed inside. A hot air inlet 11 is located on one side of the bottom of the heat sink 1, and a hot air outlet 12 is located on one side of the top. An oil tank 4 is located outside the heat sink 1. The top of the oil tank 4 is connected to the top of the heat sink 1 via a return oil pipe 5, and the bottom of the oil tank 4 is connected to the bottom of the heat sink 1 via an outlet oil pipe 6. The vertically installed oil pipes 2 inside the heat sink 1 increase the heat exchange area, allowing the hot air to more fully exchange heat with the cooling medium in the oil pipes as it flows through the heat sink, thus improving cooling efficiency. Utilizing the thermosiphon principle, hot air enters from the hot air inlet 11 at the bottom of the heat sink 1, exchanges heat with the cooling medium in the oil pipes 2, and then becomes cold air, exiting from the hot air outlet 12 at the top of the heat sink 1. Simultaneously, the cooling medium expands and rises during the heat exchange process, entering the oil tank 4 through the return oil pipe 5, and after cooling, sinks back to the heat sink 1 through the outlet oil pipe 6, forming a natural circulation flow that requires no electric drive. Since it requires no electricity to operate, this cooler consumes no electrical energy, generates no noise, and emits no harmful substances, meeting the requirements of energy conservation and environmental protection. The compact design of the heat dissipation tank 1 and oil tank 4, along with the rational layout of the oil pipe 2, return oil pipe 5, and outlet oil pipe 6, makes the entire cooler structure compact, facilitating installation and maintenance. The upper part of the oil tank 4 is connected to the return oil pipe 5 via the oil inlet 44, and the lower part of the oil tank is connected to the outlet oil pipe 6 via the oil inlet 45.

[0024] In this embodiment, the oil pipe 2 is fixed by a positioning plate 3, the surface of which is provided with several circular holes. This design ensures the stable installation of the oil pipe 2 within the heat exchange tank 1, preventing displacement of the oil pipe due to vibration or fluid impact, thereby guaranteeing the efficiency and stability of heat exchange. The circular holes on the positioning plate 3 facilitate the precise installation and positioning of the oil pipe 2, improving the convenience and accuracy of assembly. The size of the positioning plate 3 is smaller than the inner wall size of the heat exchange tank 1, so it does not obstruct the passage of gas.

[0025] Specifically, a baffle 41 is installed on the upper part of the interior of the oil tank 4, and a heat dissipation vent 42 is provided on the top of the oil tank 4. The baffle 41 can effectively prevent the cooling medium from shaking violently inside the oil tank 4, reducing energy loss and noise caused by liquid fluctuations. At the same time, the presence of the heat dissipation vent 42 increases the heat exchange area between the oil tank 4 and the external environment, which helps to improve the cooling effect and prevent the pressure inside the oil tank from becoming too high.

[0026] Furthermore, the outer wall of the oil pipe 2 is provided with external threads 21, which increases the contact area between the air and the outer wall of the pipe and improves the heat exchange effect.

[0027] Furthermore, the oil pipes 2 are arranged at equal intervals. This evenly spaced arrangement ensures that hot air is evenly distributed within the heat sink 1 and that there is sufficient heat exchange with each oil pipe. This arrangement optimizes heat exchange efficiency, reduces heat loss, and improves the overall performance of the cooler.

[0028] Furthermore, the tip of the return oil pipe 5 extends into the oil tank 4. This design ensures that the return oil pipe 5 can effectively guide the cooled medium, after thermal expansion, back into the oil tank 4, maintaining the circulation of the cooling system. The return oil pipe 5 extending into the oil tank 4 also reduces heat loss of the cooled medium during the return process, improving the system's thermal efficiency.

[0029] Furthermore, the upper part of the return oil pipe 5 is located above the liquid level in the oil tank 4, while the outlet oil pipe 6 is located at the bottom of the oil tank 4. This layout ensures effective circulation of the cooling medium within the oil tank 4. The return oil pipe 5, located above the liquid level, facilitates the receipt of heated cooling medium returning from the heat sink 1; while the outlet oil pipe 6, located at the bottom, ensures that the cooled medium can flow smoothly back to the heat sink 1, thereby maintaining the continuous operation of the system.

[0030] Furthermore, the hot air inlet 11 is connected to the hot air exhaust end of the external equipment, while the hot air outlet 12 is located at the cold air inlet end of the external equipment. This design achieves seamless integration between the cooler and the external equipment. The hot air inlet 11 directly receives hot air from the external equipment, while the hot air outlet 12 returns the cooled air to the external equipment, forming a closed loop. This layout improves the system's integration and operating efficiency, and reduces heat loss during transmission.

[0031] In operation, the non-electric thermosiphon self-circulating cooler of this invention first introduces hot air from external equipment into the bottom of the heat dissipation tank 1 through the hot air inlet 11. Inside the heat dissipation tank 1, several vertically installed oil pipes 2 increase the heat exchange area, allowing the hot air to fully exchange heat with the cooling medium within the oil pipes. During this process, the heat in the hot air is absorbed by the cooling medium, causing the hot air temperature to decrease and gradually turn into cold air.

[0032] Meanwhile, due to the thermal expansion of the cooling medium during heat exchange, its density decreases, causing it to rise and enter the oil tank 4 through the return oil pipe 5. Inside the oil tank 4, the cooling medium undergoes further heat exchange with the external environment through the heat dissipation vent 42, gradually cooling and settling. The baffle 41 effectively prevents violent shaking of the cooling medium inside the oil tank 4, reducing energy loss and noise.

[0033] The cooled medium returns to the bottom of the heat exchange tank 1 through the oil outlet pipe 6, ready for the next round of heat exchange. This creates a natural circulation flow, requiring no electricity. Throughout the process, the cooler effectively cools the hot air from external equipment through the thermosiphon effect and the principle of natural circulation, and returns the cooled air to the external equipment, forming a closed-loop circulation circuit.

[0034] Furthermore, the external threads 21 on the outer wall of the oil pipe 2 increase the contact area between the air and the outer wall of the oil pipe, further improving the heat exchange effect. The equidistant arrangement of the oil pipes 2 ensures the uniform distribution of hot air and sufficient heat exchange within the heat dissipation tank 1, optimizing the heat exchange efficiency. The reasonable layout of the return oil pipe 5 and the outlet oil pipe 6 ensures the effective circulation of the cooling medium within the oil tank 4 and the continuous operation of the system.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
