Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0020] Example 1:

[0021] A high-pressure oil-gas cooler is a device used to cool high-pressure gases or oils, and is widely used in industries such as petroleum, chemical, power, and automotive. The main function of this cooler is to effectively reduce the temperature of gases or oils under high-pressure conditions to meet process requirements or protect equipment.

[0022] Chinese patent application number 202210631197.3 discloses a high-temperature and high-pressure oil-gas air cooling method and cooling device. This patent uses sprayed atomized water droplets mixed with air to enter the oil-gas cooler for heat exchange and recycles the atomized water droplets to achieve the purpose of reducing water consumption. Although the above patent's technical solution recycles cooling water, some humidified air will be discharged into the atmosphere after heat exchange, so there is still a large loss of cooling water.

[0023] To address the problem of significant cooling water loss in existing technologies, this invention provides a high-pressure air-cooled oil-gas cooling device that can achieve cooling through complete air cooling, eliminating the need for cooling water.

[0024] like Figure 1-3 As shown:

[0025] This utility model provides a high-pressure air-cooled oil-gas cooling device, comprising a heat exchange section, a pressurizing section, an oil inlet pipeline, and an oil return pipeline, wherein: the oil inlet end of the heat exchange section is connected to the oil outlet end of the pressurizing section; the oil outlet end of the heat exchange section is connected to the oil return pipeline; the oil inlet end of the pressurizing section is connected to the oil inlet pipeline; the pressurizing section is used to pressurize the oil and gas in the oil inlet pipeline and send it into the heat exchange section; the heat exchange section includes an oil injection assembly 1, a heat exchange assembly 2, a suction assembly 3, and a collection assembly 4, wherein: the oil injection assembly 1 is located at the oil outlet end of the heat exchange assembly 2; the heat exchange assembly... The oil inlet end of 2 is connected to the oil outlet end of the pressurizing part; the pressure extraction component 3 is a hollow structure with openings at both ends and is sleeved on the outside of the heat exchange component 2. The first opening of the pressure extraction component 3 corresponds to the oil injection component 1; the collection port of the collection component 4 corresponds to the oil injection end of the oil injection component 1; the oil injection component 1 is used to spray high-pressure oil and gas toward the collection component 4 and form a low-pressure area around the oil injection port of the oil injection component 1; the pressure extraction component 3 is used to draw air from the second opening into the interior, and after passing through the surface of the heat exchange component 2, it flows toward the oil injection component 1. In the operation of the high-pressure air-cooled oil-gas cooling device provided by this utility model, the high-temperature oil-gas enters the pressurization section from the oil inlet pipe. The pressurization section is an oil pump. After pressurizing the oil-gas, the pressurization section sends it to the heat exchange section. The heat exchange section itself has a heat dissipation structure on its surface, which can dissipate heat from the oil-gas inside. When the oil-gas is sprayed out from the oil injection assembly 1, a low-pressure area is formed at the oil injection assembly 1 due to the high flow rate. Due to the Venturi effect, the low-pressure area will generate suction force on the surrounding air. The suction assembly 3 provides a channel for air flow. When one end of the suction assembly 3 is aligned with the low-pressure area at the oil injection assembly 1, the air with higher pressure at the other end will be sucked into the suction assembly 3, flow through the heat exchange assembly 2, and dissipate heat from the heat exchange assembly 2. Finally, the hot air is sprayed out from the suction assembly 3 toward one end of the oil injection assembly 1, and enters the collection assembly 4 along with the oil-gas sprayed out from the oil injection assembly 1. The collection assembly 4 collects the cooled oil-gas and discharges it into the return oil pipe to supply other equipment.

[0026] In a preferred embodiment, the heat exchange assembly 2 includes an oil-conducting square tube 21. The outer surface of the oil-conducting square tube 21 is provided with a heat dissipation fin assembly. One end of the oil-conducting square tube 21 is connected to the oil injection assembly 1; the other end of the oil-conducting square tube 21 is connected to the pressurization section; and the inner surface of the oil-conducting square tube 21 has rounded corner compensation strips 22 along its inner edges in the direction of oil and gas flow. Compared to a conventional round tube, the oil-conducting square tube 21 can increase the contact area with oil and gas, thereby improving heat dissipation efficiency. However, since turbulence easily occurs on the inner edges of a conventional square tube, leading to a decrease in oil and gas flow velocity, rounded corner compensation strips 22 are provided on the inner edges to transform them into smooth rounded corners, effectively increasing the oil and gas flow velocity and improving heat exchange efficiency.

[0027] In a preferred embodiment, the heat sink assembly includes a first heat sink 23 and a second heat sink 24, wherein: the first heat sink 23 is located near the oil inlet end of the oil-conducting square pipe 21; the first heat sink 23 is arranged along the air extraction direction of the suction assembly 3; the second heat sink 24 is located near the oil outlet end of the oil-conducting square pipe 21; the second heat sink 24 is arranged in a wave-like pattern along the air extraction direction of the suction assembly 3. Air entering the suction assembly 3 first contacts the linearly arranged first heat sink 23, which reduces air resistance and kinetic energy loss during heat exchange, while also preventing turbulence at the inlet of the suction assembly 3 from affecting air intake efficiency. After flowing a certain distance inside the suction assembly 3, the air begins to contact the second heat sink 24. Because the second heat sink 24 is arranged in a wave-like pattern, it has a larger contact area with the air, effectively improving heat exchange efficiency.

[0028] In a preferred embodiment, the fuel injection assembly 1 includes an upper spray plate 11 and a lower spray plate 12, both of which are provided with guide strips 13. The upper spray plate 11 is located in the upper half of the fuel-conducting square tube 21, and the lower spray plate 12 is located in the lower half of the fuel-conducting square tube 21. The angles between the spray surfaces of the upper and lower spray plates 11 and the fuel injection direction of the fuel injection assembly 1 are both obtuse angles. The guide strips 13 are disposed on the spray surfaces of the upper and lower spray plates 11 and 12 along the fuel injection direction of the fuel injection assembly 1. The upper and lower spray plates 11 and 12 can further compress the pressurized fuel gas, increasing the flow rate of the fuel gas during ejection and atomizing it. The atomized fuel gas can be further cooled in the air. The guide strips 13 provide guidance during further compression of the fuel gas, ensuring that the high-speed fuel gas is stably sprayed in a fixed direction.

[0029] In a preferred embodiment, the first end opening of the pressure-drawing component 3 is provided with a spray cap plate 31, and the angle between the spray cap plate 31 and the oil injection direction of the oil injection component 1 is an acute angle. The spray cap plate 31 should surround the nozzle of the oil injection component 1 to prevent the surrounding air from affecting the atomization effect of the oil and gas.

[0030] In a preferred embodiment, the collecting component 4 includes a collecting box 41 and condensing oil columns 44, wherein: the collecting box 41 has an oil collection port 42 on the side facing the spray end of the spraying component 1; the top of the collecting box 41 has an air outlet 43; the bottom of the collecting box 41 is connected to the return oil pipeline; and the condensing oil columns 44 are vertically arranged inside the collecting box 41. After the atomized oil vapor is injected into the collecting box 41, it condenses inside the collecting box 41 and collects in the collecting box 41, flowing into the return oil pipeline; setting multiple condensing oil columns 44 inside the collecting box 41 can increase the contact area between the atomized oil vapor and the inside of the collecting box 41, making the condensation efficiency of the atomized oil vapor higher.

[0031] Other embodiments of this application will readily occur to those skilled in the art upon consideration of the specification and practice of the application filed herein. This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not claimed herein.

The scope of this application is limited only by the appended claims.
