Description

Technical Field

[0001] This utility model relates to the field of heat exchanger testing technology, specifically a test bench for testing aluminum cast heat exchangers. Background Technology

[0002] A heat exchanger is an energy-saving device used to transfer heat between two or more fluids at different temperatures. It is widely used in industry, energy, construction, transportation, and other fields. Its core function is to improve energy efficiency and reduce heat waste through heat exchange, while simultaneously meeting the stringent temperature control requirements of the process flow.

[0003] The patent with publication number CN223154527U discloses a heat exchanger performance test bench, which relates to the field of heat exchanger testing technology. It includes a test bench body, with support seats slidably connected to both sides of the top of the test bench body via an adjustment mechanism. The top of each support seat has a placement groove, and the heat exchanger body is placed at the top of the two placement grooves. A slide rail is connected to one side of each support seat, and movable seats are slidably connected to both sides inside the slide rail. A movable plate is connected to one side of each movable seat. The beneficial effects of this technology are: by cooperating with the two support seats, the distance between the two support seats can be adjusted according to the length of the heat exchanger, enabling support for heat exchangers of different lengths. By cooperating with the movable seats and movable plates, two corresponding limiting plates move towards the center, clamping and limiting both ends of the heat exchanger body, preventing the heat exchanger body from shaking during performance testing, and enabling performance testing of different models of heat exchangers.

[0004] However, the above technology still has the following problems:

[0005] Manual handling of heavy heat exchangers (especially industrial-grade equipment that often weighs hundreds of kilograms) requires multiple people and is time-consuming, significantly reducing the continuity of the testing process and resulting in fewer test batches per day. Long-term high-intensity physical labor also increases the risk of occupational health problems such as lumbar muscle strain and joint injuries for operators. According to industry statistics, work-related injuries caused by such handling operations account for 62% of safety incidents in the heat exchanger testing process. From an economic and reliability perspective, the unstable posture during manual handling may cause the heat exchanger to collide with the support, resulting in minor issues such as fin and interface deformation affecting sealing, or even serious damage to core heat exchange components. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a test bench for testing aluminum cast heat exchangers, which enables mechanized lifting of the heat exchangers.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a test bench for testing aluminum cast heat exchangers, comprising a test bench body, a support plate fixedly connected to the upper surface of the test bench body, two slide rails fixedly connected to the surface of the support plate, a slider slidably connected to the slide rails, a multi-stage hydraulic rod fixedly connected to the support plate, the front end of the multi-stage hydraulic rod being fixedly connected to the side of the slider, a drive mechanism fixedly connected to the slider, a traction rope fixedly connected to the drive mechanism, a binding assembly fixedly connected to the front end of the traction rope, a connecting plate fixedly connected to the front side of the slider, and a roller mounted on the connecting plate.

[0008] Furthermore, the driving mechanism includes an L-shaped plate fixedly connected to the upper surface of the slider, a driver fixedly connected to the surface of the L-shaped plate, a rotating shaft fixedly connected to the output end of the driver, a winding drum fixedly connected to the rotating shaft, and one end of the traction rope fixedly connected to the winding drum.

[0009] Furthermore, the driver is a reversible motor.

[0010] Furthermore, an auxiliary plate is fixedly connected to the upper surface of the slider, and the rotating shaft is rotatably connected to the auxiliary plate.

[0011] Furthermore, the binding assembly includes a mounting block fixedly connected to the other end of the traction rope, two binding straps fixedly connected to the mounting block, and hooks fixedly connected to the front ends of the binding straps.

[0012] Furthermore, the surface of the strap is provided with anti-slip particles.

[0013] Furthermore, two triangular plates are mounted on the surface of the support plate, and the upper surfaces of the two triangular plates are fixedly connected to the lower surface of the slide rail.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This type of test bench for aluminum cast heat exchangers offers several advantages. First, it replaces the traditional method of manually handling heavy heat exchangers (often weighing hundreds of kilograms), significantly reducing the physical labor intensity of workers and lowering occupational health risks such as lumbar muscle strain and joint damage caused by long-term high-intensity handling, thus reducing related work-related accidents (which account for 62% of safety incidents in existing testing processes). Second, it greatly improves handling efficiency, avoiding the time-consuming problem of multiple people working together (each handling is relatively time-consuming), enhancing the continuity of the testing process, and effectively increasing the number of test batches per day (existing technologies reduce batches by about 30% due to manual handling). Third, it achieves stable hoisting and translation through mechanical structures, combined with anti-slip straps and precise speed control (such as a forward and reverse motor with a gearbox to adjust the lowering speed), avoiding collisions between the heat exchanger and the support base caused by unstable postures during manual handling, protecting vulnerable components such as fins and interfaces, preventing deformation from affecting sealing or damaging core heat exchange elements, and ensuring the structural integrity of the heat exchanger before testing.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 3 A test bench for testing aluminum cast heat exchangers includes a test bench body 1. A support plate 2 is fixedly connected to the upper surface of the test bench body 1. Two slide rails 3 are fixedly connected to the surface of the support plate 2. A slider 4 is slidably connected to the slide rails 3. A multi-stage hydraulic rod 5 is fixedly connected to the support plate 2. The front end of the multi-stage hydraulic rod 5 is fixedly connected to the side of the slider 4. A drive mechanism is fixedly connected to the slider 4. A traction rope 6 is fixedly connected to the drive mechanism. A binding assembly is fixedly connected to the front end of the traction rope 6. A connecting plate 7 is fixedly connected to the front side of the slider 4. A roller 8 is installed on the connecting plate 7.

[0022] The test bench for testing aluminum cast heat exchangers in this utility model is structurally similar to existing heat exchanger performance test benches, such as the one disclosed in patent announcement number CN223154527U. The main improvement of this utility model is that it allows for the hoisting of the heat exchanger, reducing the physical exertion of workers and minimizing damage to the heat exchanger during handling. Figures 1 to 3 As shown, in use, the aluminum cast heat exchanger testing platform of this utility model fixes the aluminum cast heat exchanger to be tested by the binding assembly, then starts the drive mechanism, and lifts the heat exchanger to the preset height by the traction rope 6. Then, the multi-stage hydraulic rod 5 pushes the slider 4 to move along the slide rail 3, driving the heat exchanger to the designated testing position of the test platform body 1. The drive mechanism is then reversed to slowly lower the heat exchanger to the testing position, completing the transportation process.

[0023] like Figure 3As shown, the driving mechanism includes an L-shaped plate 9 fixedly connected to the upper surface of the slider 4, a driver 10 fixedly connected to the surface of the L-shaped plate 9, a rotating shaft 11 fixedly connected to the output end of the driver 10, a winding drum 12 fixedly connected to the rotating shaft 11, and one end of the traction rope 6 fixedly connected to the winding drum 12.

[0024] Specifically, the driver 10 is started to rotate forward, causing the shaft 11 and the winding drum 12 to rotate synchronously, winding up the traction rope 6. At this time, the traction rope 6 is guided by the roller 8 (the roller 8 is mounted on the connecting plate 7 to reduce friction between the traction rope 6 and other components), lifting the binding assembly and heat exchanger upwards until the bottom of the heat exchanger is higher than the test platform surface of the test bench body 1. Then, the driver 10 is started to rotate in reverse, and the winding drum 12 releases the traction rope 6, allowing the heat exchanger to slowly descend under its own weight. By controlling the rotational speed of the driver 10 (e.g., using a motor with a gearbox), the descent speed can be precisely adjusted to avoid impact damage to the heat exchanger.

[0025] like Figure 3 As shown, the driver 10 is a forward and reverse rotating motor.

[0026] Specifically, the forward and reverse motor can control the rotation direction of the rotating shaft 11.

[0027] like Figure 3 As shown, an auxiliary plate 13 is fixedly connected to the upper surface of the slider 4, and the rotating shaft 11 is rotatably connected to the auxiliary plate 13.

[0028] Specifically, the auxiliary plate 13 on the upper surface of the slider 4 is rotatably connected to the rotating shaft 11, which can share the radial load of the rotating shaft 11, prevent the rotating shaft 11 from bending and deforming due to cantilever stress after long-term use, and improve the stability and service life of the drive mechanism.

[0029] like Figure 1 As shown, the binding assembly includes a mounting block fixedly connected to the other end of the traction rope 6, and two binding straps 14 are fixedly connected to the mounting block. A hook 15 is fixedly connected to the front end of the binding straps 14.

[0030] Specifically, the heat exchanger is initially secured by placing it on two straps 14 and then hanging the hooks 15 on the straps 14 (or on the hanging points of the heat exchanger).

[0031] like Figure 1 As shown, the surface of the strap 14 is provided with anti-slip particles.

[0032] Specifically, the anti-slip particles can increase the friction between the heat exchanger and the strap 14, thereby reducing the possibility of the heat exchanger rotating during hoisting.

[0033] like Figure 1As shown, two triangular plates 16 are mounted on the surface of the support plate 2, and the upper surfaces of the two triangular plates 16 are fixedly connected to the lower surface of the slide rail 3.

[0034] Specifically, the triangular plate 16 is used to provide auxiliary support for the slide rail 3, improve the stability of hoisting the heat exchanger, and reduce the possibility of the slide rail 3 bending.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
