[0001] This application relates to the field of testing equipment for internal combustion engine equipment, and more particularly to a single-section heat dissipation test bench. Background Technology

[0002] The cooling unit is an indispensable and important component of the cooling system of a diesel locomotive. During the maintenance of a diesel locomotive, it is necessary to conduct flow and pressure tests on the cooling unit. By simulating the flow and pressure during locomotive operation on a test bench, the heat dissipation efficiency of the cooling unit can be analyzed.

[0003] When testing a heat dissipation unit on a test bench, it needs to be fixed to the base of the test bench with multiple bolts so that the heat dissipation unit can be connected and clamped to the flow and pressure interfaces located on the base of the test bench.

[0004] However, the way this heat dissipation unit is fixed to the test bench base is very troublesome, resulting in low testing efficiency. Utility Model Content

[0010] When the mounting bracket is in the first state, the clamping member is located above the base and opposite to the base, and the space between the clamping member and the base is used to accommodate the heat dissipation unit.

[0011] When the mounting bracket is in the second state, the clamping member is not opposite to the base, and the base can be used to place the heat dissipation unit.

[0018] The first connector is connected to the first end of the main body, and the second connector is connected to the second end of the main body. Both the first connector and the second connector are rotatably connected to the base through a rotating part.

[0019] In some embodiments of this application, the mounting bracket includes a body that is spaced apart from the base, and the clamping member is positioned close to or away from the body between the body and the base.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0045] As mentioned in the background section, the cooling unit is a key component of the internal combustion locomotive's cooling system. It typically consists of multiple fins and pipes, used to transfer heat generated by the engine to the air via coolant, thereby maintaining the engine's operation within a suitable temperature range. The performance of the cooling unit directly affects the operating efficiency and reliability of the internal combustion locomotive.

[0046] Gasoline locomotive engines generate a large amount of heat during operation. If this heat is not dissipated in time, it can lead to overheating, causing malfunctions or damage. Effective cooling of the cooling system can maintain the engine at its optimal operating temperature, improving combustion efficiency and power output.

[0047] Effective temperature management can reduce thermal stress and wear on engine components, thus extending their service life.

[0048] Flow and pressure tests can verify the heat dissipation performance of the cooling unit under different operating conditions, ensuring that it meets design requirements. Flow and pressure tests on the cooling unit can also help identify potential leaks, preventing coolant loss and ensuring system sealing. By simulating the flow and pressure conditions during locomotive operation, the actual heat dissipation efficiency of the cooling unit can be evaluated, ensuring its effective operation in real-world scenarios. During maintenance, flow and pressure tests can help identify the causes of cooling unit failures or performance degradation, providing a basis for repair.

[0049] The existing method of clamping the heat dissipation unit test bench is to tighten the heat dissipation unit to the test bench with bolts. There are a lot of heat dissipation units, and each heat dissipation unit needs to be tested. All four corresponding bolt holes need to be tightened. After the test is completed, all the units are removed and replaced with other heat dissipation units for testing. Due to the limited working space where the bolts are located, the workload is large and the work efficiency is low.

[0050] In view of this, the present application provides a single-section heat dissipation test bench. By using movable mounting brackets and clamping components, the time and manpower required for traditional bolt fixing methods are reduced. Operators no longer need to tighten and loosen bolts one by one, thereby significantly improving test efficiency. The clamping components can be quickly clamped and released through simple operation, reducing the requirements for operating space, especially in cases of limited space. Due to the mobility of the mounting brackets, this design makes it easier to place larger heat dissipation sections on the base, improving test efficiency.

[0051] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0052] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0053] refer to Figure 1 This application provides a single-section heat dissipation test bench:

[0054] Includes base 100, which can be used to support the heat dissipation unit.

[0055] It also includes a mounting bracket 200, which can be movably mounted on the base 100; the mounting bracket 200 is provided with a clamping member 300, which can be close to or away from the base 100, and the clamping member 300 is used to clamp the heat dissipation unit.

[0056] It is known that the base 100 is used to support the heat sink section and provide a stable support structure. It should be noted that the design of the base should take into account the different sizes and types of heat sink sections in order to adapt to diverse testing needs.

[0057] The mounting bracket 200 is movably mounted on the base 100, allowing for adjustment at different positions on the base 100, which facilitates the placement of larger heat dissipation sections on the base 100.

[0058] The clamping component 300 is designed to clamp the heat dissipation unit to ensure that it is stably fixed to the base 100 for subsequent testing.

[0059] Therefore, by using the movable mounting bracket 200 and clamping element 300, the time and manpower required for traditional bolt fixing methods are reduced, and operators no longer need to tighten and loosen bolts one by one, thus significantly improving test efficiency. The clamping element 300 can be quickly clamped and released through simple operation, reducing the requirements for operating space, especially in cases where space is limited. Due to the mobility of the mounting bracket 200, this design makes it easier to place larger heat dissipation sections on the base 100, improving test efficiency.

[0060] In some possible implementations, the mounting bracket 200 is provided with a rotating part 400, and the mounting bracket 200 is rotatably connected to the base 100 via the rotating part 400.

[0061] When the mounting bracket 200 is in the first state, the clamping member 300 is located above the base 100 and opposite to the base 100. The clamping member 300 and the base 100 are used to accommodate the heat dissipation unit.

[0062] When the mounting bracket 200 is in the second state, the clamping member 300 is not opposite to the base 100, and the base 100 can be used to place the heat sink section.

[0063] The rotating part 400 allows the mounting bracket 200 to rotate on the base 100, facilitating the installation and removal of the heat dissipation unit.

[0064] In the first state, the clamping part on the mounting bracket 200 is located above the base 100, pressing the heat dissipation unit onto the base 100 to ensure stability during the test.

[0065] In the second state, the mounting bracket 200 rotates so that the clamping member 300 is no longer opposite the base 100. At this time, the space above the base 100 is more open, making it easier to place or remove the heat sink section, and facilitating replacement and adjustment.

[0066] The design of the rotating part 400 allows the mounting bracket to be easily rotated to an open position on the base 100, making the installation and disassembly of the heat dissipation unit quicker and reducing operation time. The design in the second state allows for a larger operating space, facilitating the placement and adjustment of the heat dissipation unit and improving the flexibility and operability of the test bench. By reducing complex bolt operations, safety hazards caused by operational errors are reduced, while ensuring the reliability of each test.

[0067] In some possible implementations, the rotating part 400 is detachably connected to the base 100.

[0068] It is known that the rotating part 400 is detachably connected to the base 100, which means that in actual use, the rotating part 400 can remove the mounting bracket 200 from the base 100 when needed, thus increasing the operating space above the base 100.

[0069] The detachable design of the rotating part 400 allows the mounting bracket 200 on the base 100 to be configured as needed to adapt to different testing requirements and operating environments. Simultaneously, the detachability of the rotating part 400 allows for easy removal and handling of major components of the heat dissipation single-section test bench when maintenance or replacement is required, facilitating maintenance and replacement. Removing the rotating part 400 separates the mounting bracket 200 from the base 100, freeing up more operating space and improving the neatness and operability of the work area.

[0070] In some possible implementations, the rotating part 400 is configured as a rotating bolt, which includes a threaded part and a smooth part.

[0071] The threaded part passes through the base 100 and is threadedly connected to the base 100.

[0072] The smooth part passes through the mounting bracket 200 and is rotatably connected to the mounting bracket 200.

[0073] It is known that the design of the threaded part allows the rotating bolt (rotating part 400) to be fixed on the base 100, and at the same time allows the mounting bracket 200 to be fixed relative to the base 100.

[0074] The smooth part design allows the mounting bracket 200 to rotate around the rotating bolt (rotating part 400), thereby enabling the mounting bracket 200 to switch states (such as from the first state to the second state).

[0075] During use, rotating the rotating bolt gradually increases the contact area between the threaded part and the base 100, that is, screwing the rotating bolt into the base 100, increasing the pressure of the rotating bolt on the mounting bracket 200 on the base 100, so that the mounting bracket 200 and the base 100 are relatively fixed.

[0076] In contrast to the above process, rotating the bolt in the opposite direction gradually reduces the contact area between the threaded part and the base 100, that is, it loosens the rotating bolt from the base 100. The pressure of the rotating bolt on the mounting bracket 200 on the base 100 is reduced or even eliminated, so that the mounting bracket 200 and the base 100 can move relative to each other.

[0077] By using the design of the rotating bolt (rotating part 400), the mounting bracket 200 can be easily rotated to a relatively open position, avoiding the space above the base 100, making the installation and removal of the heat dissipation section quicker and reducing operation time; the threaded connection between the threaded part and the base provides stable fixation, while the smooth part allows the necessary rotation function, ensuring the reliability of the entire device.

[0078] refer to Figure 2In some possible implementations, the mounting bracket 200 includes a main body 210 and a connector 220, with the main body 210 connected to the rotating part 400 via the connector 220.

[0079] The main body 210 is connected to the clamping member 300, and the clamping member 300 can move closer to or further away from the main body 210.

[0080] It is known that the main body 210 is the main structural part of the mounting bracket 200, responsible for supporting and fixing the clamping component 300;

[0081] The main body 210 can be rotated or moved via the rotating part 400 through the connector 220, thereby adjusting the position of the clamping member 300.

[0082] For example, the main body 210 is arranged perpendicularly to the mounting bracket 200 to ensure the stability of the support for the clamping member 300.

[0083] Through the design of the main body 210 and the connector 220, the clamping part 300 can quickly approach or move away from the heat dissipation section, reducing operation time and labor intensity; the mounting bracket 200 has a simple structure but ensures support strength, has low production cost, and ensures equipment reliability.

[0084] In some possible implementations, there are multiple connectors 220, including a first connector 221 and a second connector 222.

[0085] The first connector 221 is connected to the first end of the main body 210, and the second connector 222 is connected to the second end of the main body 210. Both the first connector 221 and the second connector 222 are rotatably connected to the base 100 through a rotating part 400.

[0086] It is understood that the design of multiple connectors 220 (first connector 221 and second connector 222) provides better stability and flexibility.

[0087] The rotating part 400 is used to connect the connector 220 and the base 100, allowing the connector 220 to rotate about its axis, thereby enabling adjustment of the main body 210.

[0088] Therefore, the use of multiple connectors 220 provides better support and stability, ensuring that the clamping member 300 on the main body 210 remains stable during operation; by using the first connector 221 and the second connector 222 at both ends of the main body 210, the mounting bracket 200 can provide more space for the heat dissipation unit on the base 100, accommodating heat dissipation units of different sizes and shapes; through stable support and flexible adjustment, the clamping member 300 can provide uniform pressure, ensuring the accuracy of the heat dissipation unit test.

[0089] In some possible implementations, the mounting bracket 200 includes a body 210 that can be spaced apart from the base 100, and the clamping member 300 can be close to or away from the body 210 between the body 210 and the base 100.

[0090] It is known that the main body 210 can be spaced apart from the base 100. This means that the main body 210 can be suspended above the base 100 at a certain distance, providing space for the placement and operation of the heat dissipation unit. The spacing design between the main body 210 and the base 100 allows for additional operating space without affecting the function of the base.

[0091] The clamping element 300 is movable between the body 210 and the base 100, specifically by moving closer to or further away from the body. This design allows the clamping element 300 to apply pressure when needed to secure the heat dissipation unit, or to release pressure when not needed for easy replacement.

[0092] Therefore, by setting the body 210 and the base 100 at an interval, the clamping member 300 can move quickly between the body 210 and the base 100, reducing operation time and labor intensity; the above design allows operators to adjust the position of the clamping member 300 through simple operation without complicated bolt operation, reducing labor intensity; the spacing design between the body 210 and the base 100 provides a larger operating space, enabling the device to adapt to heat dissipation sections of different sizes and shapes.

[0093] refer to Figure 4 In some possible implementations, the main body 210 is provided with a drive screw 500, which is threadedly connected to the main body 210, and the output end of the drive screw 500 is rotatably connected to the clamping member 300.

[0094] It is known that the drive screw 500 is threadedly connected to the main body 210, and can rotate within the main body 210 and move along the thread. When the drive screw 500 is rotated, the clamping member 300 achieves precise linear movement. The clamping member 300 is connected to the output end of the drive screw 500 through a rotatable connection, so that the clamping member 300 moves closer to or away from the heat dissipation section under the drive of the drive screw 500, thereby achieving clamping or release.

[0095] The design of the drive screw 500 allows operators to quickly adjust the position of the clamping element 300 by rotating the screw 211, simplifying operation and reducing operation time and labor intensity. The drive screw 500 provides precise linear motion control, enabling the clamping element 300 to apply uniform and controllable pressure, ensuring the accuracy of the heat dissipation section test. The above design allows operators to adjust the position of the clamping element 300 with a simple rotational action, eliminating the need for complex and repetitive bolt installation operations, thus reducing labor intensity. The use of the drive screw 500 provides greater operational flexibility, enabling the device to adapt to heat dissipation sections of different sizes and shapes.

[0096] In some possible embodiments, a clamping pad (not shown) is provided at the bottom of the connector 220, and the clamping pad may be made of a flexible elastic material.

[0097] The clamping gasket can be made of rubber, which has good elasticity and can increase friction when in contact with the heat dissipation unit, preventing slippage.

[0098] By using a clamping pad, the connection between the connector 220 and the heat sink section is more secure, and the connector 220 is prevented from directly contacting the heat sink section, thus avoiding scratches on the surface of the heat sink section.

[0099] refer to Figure 3 In some possible implementations, the clamping member 300 includes a plurality of clamping portions 310 spaced apart, the clamping portions 310 being used to abut against the surface of the heat dissipation unit away from the base 100.

[0100] In some possible implementations, when the drive screw 500 moves the clamping member 300 closer to or away from the main body 210, the clamping part 310 slides into contact with the mounting bracket 200 (this embodiment is not shown in the figure).

[0101] It is understood that the clamping part 310 is used to abut against the surface of the heat sink section away from the base 100, thereby achieving effective clamping of the heat sink section.

[0102] The spaced arrangement of multiple clamping parts 310 ensures uniform pressure distribution on the heat dissipation section, improving the stability of the fixation.

[0103] With the design of multiple clamping parts 310, the clamping member 300 can quickly and evenly apply pressure, reducing operation time and labor intensity; the multiple clamping parts 310 ensure uniform pressure distribution on the heat dissipation section, improving the sealing effect of the test.

[0104] The design of the clamping part 310 slidingly contacting the mounting bracket 200 allows the clamping part 310 to remain stable during movement, reducing friction and wear, and improving the durability and reliability of the system.

[0105] In some possible implementations, a locking key 510 is provided at the bottom of the drive screw 500. By providing the locking key 510, the clamping member 300 is prevented from disengaging from the drive screw 500, thereby improving the reliability of the device.

[0106] In some possible implementations, a handle 520 is provided on the top of the drive screw 500. The handle 520 facilitates the application of driving force to the drive screw 500, making operation convenient and saving time and effort.

[0107] In some possible implementations, the base 100 is provided with an upward-facing test port 110 for communication with a heat dissipation unit.

[0108] It is known that this design of the test port 110 allows the test port 110 to be directly connected to the heat dissipation section on the base 100, facilitating the transmission of flow and pressure.

[0109] The design of the test port 110 allows the heat dissipation unit to be directly placed on the base 100 for connection, reducing complex docking operations and improving connection efficiency. Operators can easily place the heat dissipation unit on the base 100 and quickly connect it through the test port 110, reducing labor intensity. Integrating the test port 110 into the base 100 reduces the size of the equipment and facilitates testing a larger number of heat dissipation units at the test site.
