Description

Technical Field

[0001] This utility model relates to the field of coupling technology, and in particular to a cooling device for assisting in the ion penetration treatment of coupling surfaces. Background Technology

[0002] In the petroleum industry, couplings are the core components of oil and gas well tubing connections. They are mainly used to connect single steel pipes into a continuous, sealed tubing string with load-bearing capacity. They are key components to ensure the safety of oil and gas extraction and transportation. To solve the problems of wear, corrosion, and fatigue of couplings in the harsh downhole environment, they usually need to be ion-impregnated to improve surface hardness and wear resistance. During the use of ion-impregnating agents, the temperature is usually higher than 500°C. If the composition of the impregnating agent is to be tested, the sample must be cooled after extraction.

[0003] Existing cooling chambers are mostly single-layer straight-channel structures, resulting in short residence time of the medium within the chamber and insufficient heat exchange, leading to low cooling efficiency. With samples fixed in place, only a portion of the surface comes into contact with the cooling medium, easily creating cooling dead zones and causing significant temperature differences across different parts of the sample, exacerbating uneven cooling. To improve these issues, existing technologies add guide plates to the inner wall of the cooling chamber to extend the medium path, or use manual rotation of the sample holder to adjust the sample position. They also add multiple independent pipelines to achieve zoned flow. However, in practical use, the added guide plates are mostly straight plates, failing to guide the medium to form a continuous flow path, resulting in limited improvement in heat exchange efficiency. Manually rotating the sample holder requires frequent manual operation, increasing workload and failing to guarantee a stable rotation rate, thus providing poor improvement in cooling uniformity.

A caster wheel is installed at each of the four corners of the bottom of the support platform. A drive motor is fixedly connected to the outer wall of each caster wheel, and a support assembly is installed on the outer side of each caster wheel.

[0009] Preferably, the support assembly includes bearings, which are fixedly connected to the four corners of the bottom wall of the support platform.

The right outer wall of the outer shell 1 is equidistantly connected with liquid inlets 2023, and the bottom of the multiple liquid inlets 2023 is provided with liquid outlets 2024, which are connected to the right side of the outer wall of the outer shell 1. The drive assembly 205 includes a stepper motor 2051, model 57BYGH, which converts electrical pulse signals into angular or linear displacement. For each input pulse signal, the motor rotates by a fixed angle, achieving precise positioning and operation control. The stepper motor 2051 is located at the bottom right side of the housing 1. The output end of the stepper motor 2051 is fixedly connected to a gear shaft 2052. A bevel gear 2053 is meshed with the top left side of the gear shaft 2052. The rotating shaft 204 is fixedly connected to the middle of the top wall of the rotating shaft 204. Specifically, the inner shell 201 is a cavity structure with an open top, which holds the sample to be tested. The outer shell 1 is a hollow cylindrical structure fitted over the inner shell 201, and the two are coaxially arranged. The annular space between the inner wall of the outer shell 1 and the outer wall of the inner shell 201 forms a cooling chamber. Coolant at a preset temperature flows continuously inside the cooling chamber. The coolant removes heat from the sample through contact with the outer wall of the inner shell 201. Three partition plates 2022 are evenly distributed along the axial direction of the outer shell 1, dividing the cooling chamber into three independent parts. Each independent part of the outer shell 1 is equipped with an inlet 2023 and an outlet 2024 on its side wall. Each compartment is connected to an external pipeline through the corresponding inlet 2023 and outlet 2024 to form a relatively independent heat dissipation cycle. The coolant is injected into the cooling chamber through the pipeline from the inlet 2023. The coolant entering the cooling chamber is guided by the guide vanes 2021 fixed to the outer wall of the inner shell 201 and flows in a spiral shape along the guide vanes 2021. After flowing around the outer wall of the inner shell 201, the coolant is discharged from the cooling chamber through the outlet 2024. The outer wall of the inner shell 201 has several heat dissipation ridges 9 evenly distributed along its axial and circumferential directions. The heat dissipation ridges 9 increase the contact area between the inner shell 201 and the coolant, accelerating the heat exchange process. The bottom of the outer shell 1 is fixedly connected to the upper surface of the base 203 and connected to the support device through the base 203. The base 203 also serves as the bottom plate of the cooling chamber, sealing the bottom of the cooling chamber. The output shaft of the stepper motor 2051 is connected to one end of the gear shaft 2052, driving the gear shaft 2052 to rotate. The other end of the gear shaft 2052 drives the bevel gear 2053 to rotate. The other end of the rotating shaft 204 passes through the base 203 and is fixedly connected to the bottom center of the inner shell 201, thereby driving the inner shell 201 to rotate at a fixed angle inside the outer shell 1. During the rotation of the inner shell 201, the surfaces of the sample can alternately contact the cooling medium sprayed inside the cooling chamber, further eliminating the phenomenon of uneven cooling of different surfaces of the sample.

Universal wheels 302 are installed at the four corners of the bottom of the support platform 301. A drive motor 303, model Y132M-4, is fixedly connected to the outer wall of the multiple universal wheels 302. When AC power is applied to the stator winding of the motor, a rotating magnetic field is generated. The induced current is driven by the force of the rotating magnetic field to rotate the rotor. A support assembly 304 is installed on the outer side of the multiple universal wheels 302. The support assembly 304 includes a bearing 3041, which is fixedly connected to the four corners of the bottom wall of the support platform 301. A threaded tube 3042 is rotatably connected to the bottom of the bearing 3041, and a threaded rod 3043 is threadedly connected to the inner wall of the threaded tube 3042. The top wall of the support platform 301 is fixedly connected with an anti-slip pad 4, the middle of the outer shell 1 is provided with a mounting groove 5, the outer wall of the drive motor 303 is fixedly connected with a motor bracket 8, and the top left side of the support platform 301 is fixedly connected with a handle 6. Specifically, multiple casters 302 are evenly distributed at the four corners and edges of the bottom of the support platform 301. The axles of the casters 302 are hinged to the bottom bracket of the support platform 301, allowing the support platform 301 to move to the designated work position in any direction according to the work requirements. At the same time, the casters 302 can rotate in multiple directions to adjust the movement direction to adapt to different work needs. The drive motor 303 provides power for the rotation of the casters 302. After the equipment has moved to the target position, the operator uses tools to rotate the threaded tubes 3042 at different positions on the bottom of the support platform 301. The outer wall of the middle part of the threaded tube 3042 is fixedly connected to the inner ring of the bearing 3041. The vertical position of 3042 is fixed by bearing 3041. The top end of threaded rod 3043 is connected to the inner wall of threaded tube 3042 by threaded engagement. As threaded tube 3042 rotates, threaded rod 3043 moves downward in the vertical direction. During the downward movement of threaded rod 3043, threaded tube 3042 moves upward relative to support platform 301. Each support component 304 is composed of bearing 3041, threaded tube 3042 and threaded rod 3043. Different support components 304 can be independently adjusted in height. By adjusting the height of each support component 304, it can adapt to places with different ground flatness, avoid tilting of support platform 301 and prevent samples placed on heat dissipation mechanism 2 from tipping over.

[0020] Reference Figure 3 and Figure 5 The outer wall of the inner shell 201 is provided with multiple heat dissipation ridges 9 at equal intervals, and a rotating block 7 is fixedly connected to the middle of the outer wall of the threaded tube 3042. Specifically, the heat dissipation ridge 9 increases the contact area between the coolant and the inner shell 201, improving heat dissipation efficiency, and the rotating block 7 is hexagonal prism-shaped and can be rotated with a hexagonal wrench.

[0021] Working principle: The sample to be tested is placed inside the inner shell 201. The outer shell 1 is fitted over the inner shell 201, and the space between them forms a cooling chamber. Coolant flows inside to remove heat from the sample. The isolation plate 2022 divides the cooling chamber into three parts, each equipped with an inlet 2023 and an outlet 2024. Each chamber has a relatively independent heat dissipation circulation. Cooled blood is injected into the cooling chamber through the inlet 2023, and after being guided by the guide plate 2021, it flows in a spiral shape, flows around the outer wall of the inner shell 201, and is discharged through the outlet 2024. The outer wall of the inner shell 201 is distributed with diffusers... The heating element 9 accelerates the heat exchange process. The outer shell 1 is connected to the support device via the base 203, serving as the bottom plate of the cooling chamber. The stepper motor 2051 drives the gear shaft 2052 and bevel gear 2053 to rotate, and drives the rotating shaft 204 and the inner shell 201 to rotate at a fixed angle inside the outer shell 1, so that each surface of the sample can alternately contact the sprayed cooling medium, further eliminating the phenomenon of uneven cooling. This set of equipment can extend the heat dissipation path, alleviate the phenomenon of uneven heating and cooling, and does not require manual operation of rotation. It solves the problems of limited improvement in heat exchange efficiency, inability to guarantee stable rotation speed, and poor improvement effect of cooling uniformity in the existing technology. The support platform 301 serves as the base of the heat dissipation mechanism 2. Multiple casters 302 are distributed at the bottom, allowing the support platform 301 to be moved to the working position as needed. It can rotate in multiple directions to adapt to working requirements. The drive motor 303 provides power for the rotation of the casters 302. After the equipment has been moved, the threaded tubes 3042 at different positions are rotated. The vertical position of the threaded tubes 3042 is fixed by the bearings 3041. The threaded rod 3043 moves downward as it rotates, causing the threaded tubes 3042 to move upward relative to each other. Different support components 304 can be adjusted independently to adapt to places with different flatness and prevent the sample from tipping over.
