Description

Technical Field

[0001] This utility model relates to the field of radiator manufacturing technology, and in particular to a radiator core vibration damping device. Background Technology

[0002] Plate-fin radiators are core components of cooling systems in construction machinery. Existing radiators typically use rigid connections for fixation, meaning the radiator core frame is directly bolted to the equipment's metal frame. However, in actual use, especially on equipment like excavators and loaders, radiators are subjected to severe mechanical vibrations. Because the core is made of multiple layers of thin aluminum plates brazed together, the rigid connection directly transmits external vibration energy to the core, causing stress concentration in the internal welds. Over time, this can easily lead to cracks and leaks.

[0003] Furthermore, the radiator experiences drastic temperature changes during operation, causing the core to expand and contract with temperature. Traditional rigid frames tightly hold the core in place, restricting its free expansion and resulting in enormous thermal stress within the core, further accelerating structural damage.

[0004] Therefore, this application provides a radiator core vibration damping device to meet the requirements. Utility Model Content

[0005] The purpose of this application is to provide a radiator core vibration damping device, which aims to solve the problems of poor vibration resistance and inability to release thermal stress caused by rigid connection of radiators in the prior art.

[0006] To achieve the above objectives, this application provides the following technical solution: a radiator core vibration damping device, comprising a radiator core unit and a rigid protective frame assembly covering the outer periphery of the radiator core unit; the rigid protective frame assembly includes a plurality of lateral load-bearing groove beams, and a U-shaped receiving cavity is formed on the inner side of the lateral load-bearing groove beams along the length direction; the core edge of the radiator core unit extends into the interior of the U-shaped receiving cavity; a plurality of flexible suspension pads are filled between the core edge and the inner wall of the U-shaped receiving cavity; the radiator core unit forms a non-contact suspension connection with the lateral load-bearing groove beams through the flexible suspension pads.

[0007] Preferably, the flexible suspension pad is a U-shaped rubber shock absorber or a silicone buffer block. The flexible suspension pad covers the outer surface of the core edge and is inserted into the U-shaped receiving cavity of the lateral load-bearing channel beam together with the core edge.

[0008] Preferably, the lateral load-bearing groove beams are respectively arranged on the upper and lower long sides of the radiator core unit; the rigid protection frame assembly further includes an end limiting sealing plate connecting the upper and lower lateral load-bearing groove beams; the inner side wall of the end limiting sealing plate is fixedly provided with a positioning protrusion, which is used to axially limit the side of the radiator core unit.

[0009] Preferably, the outer wall of the lateral load-bearing channel beam is welded with a number of side-mounted lifting lugs at intervals; the side-mounted lifting lugs are L-shaped and have waist-shaped mounting holes on their mounting surfaces.

[0010] Preferably, the rigid protective frame assembly is further provided with a back protective mesh plate, which is fixedly connected to the lateral load-bearing channel beam by bolts.

[0011] Preferably, the bottom surface of the lateral load-bearing channel beam is provided with a plurality of fluid connection interfaces, the fluid connection interfaces are connected to the internal flow channels of the radiator core unit, and the fluid connection interfaces serve as elastic support fulcrums at the bottom of the entire device.

[0012] In summary, the technical effects and advantages of this utility model are as follows: 1. In this utility model, a flexible suspension liner is installed inside the U-shaped receiving cavity of the rigid protective frame assembly, achieving a non-contact soft connection between the radiator core unit and the external frame. When the equipment experiences severe vibration, the flexible layer can effectively block the transmission of vibration waves to the core, playing a significant role in shock absorption and buffering.

[0013] 2. In this invention, the flexible suspended pad not only serves as a shock absorber but also provides a buffer space for the thermal expansion of the radiator core unit. When the core expands due to heat, the flexible pad deforms under pressure, preventing the core from being squeezed and deformed by the rigid frame, effectively releasing thermal stress and extending the service life of the radiator.

Detailed Implementation

[0017] 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. Example

[0018] refer to Figure 1-4 The illustrated radiator core vibration damping device includes a core heat exchange component—a radiator core unit 100—and a rigid protective frame assembly 300 for supporting and protecting the core. The rigid protective frame assembly 300 is not rigidly locked to the radiator core unit 100, but is connected via a special suspension structure.

[0019] As one implementation method in this embodiment, as shown in the figure, the rigid protective frame assembly 300 adopts a split-assembly design, mainly composed of lateral load-bearing channel beams 310 symmetrically distributed on the upper and lower sides, end limiting sealing plates 320 on the left and right sides, and a back protective mesh plate 330 on the back, assembled by fasteners such as high-strength bolts. This split structure facilitates the later maintenance and replacement of the radiator.

[0020] As one embodiment of this work, as shown in the figure, the lateral load-bearing channel beam 310 is preferably made of aluminum alloy profile or bent steel plate, and its inner side naturally forms an inwardly opening U-shaped receiving cavity 311 along its length. The core edge 110 of the radiator core unit 100 extends and inserts into the U-shaped receiving cavity 311. The key technical point of this embodiment is that the core edge 110 does not directly contact the metal channel wall, and a number of flexible floating pads 200 are filled between them.

[0021] In one embodiment of this work, the flexible suspension pad 200 is made of high-temperature resistant silicone or fluororubber, possessing excellent damping characteristics and weather resistance. In the assembly process, the flexible suspension pad 200 is U-shaped and wraps around the outer side of the core edge 110, then is press-fitted together with the core into the U-shaped receiving cavity 311 of the lateral load-bearing channel beam 310. This structure allows the radiator core unit 100 to be effectively "suspended" inside the rigid frame, achieving a non-contact, flexible connection between the core and the frame.

[0022] As one implementation method in this embodiment, to adapt to the requirements of vertical installation, several side-mounted lifting lugs 312 are welded to the outer wall of the lateral load-bearing channel beam 310. The side-mounted lifting lugs 312 have an L-shaped structure, and the entire device is fixed to the frame of the external equipment through the waist-shaped holes on them. When external vibration is transmitted to the frame through the lifting lugs, the flexible suspension pad 200 filters out most of the high-frequency vibration energy, protecting the fragile brazed seams inside the core from cracking.

[0023] As one embodiment of this invention, as shown in the figure, the inner wall of the end limiting sealing plate 320 is welded or integrally formed with a positioning protrusion 321. After the frame is assembled, the positioning protrusion 321 will abut against the side end of the radiator core unit 100, restricting excessive displacement of the core in the horizontal axis, preventing the core from slipping off the side under bumpy road conditions, and ensuring the stability of the overall structure.

[0024] As one embodiment of this work, as shown in the figure, the bottom of the lateral load-bearing trough beam 310 is also provided with a fluid connection interface 400 for connecting to the coolant pipeline. In this design, the fluid connection interface 400 has sufficient structural strength and can also serve as an auxiliary elastic support fulcrum at the bottom of the entire device, further sharing the weight of the core and coolant.

[0025] The working principle of this utility model is as follows: During equipment operation, the radiator core unit 100 undergoes thermal expansion due to absorbing heat from the coolant. Since the core edge 110 is fully enclosed by the flexible suspension pad 200 and suspended within the groove, the expanding core compresses the flexible suspension pad 200, thus obtaining a buffer space for free expansion and contraction, avoiding the enormous thermal stress caused by rigid constraints. Simultaneously, when severe impacts occur during engineering machinery operation, the relative displacement of the core under inertia is absorbed by the flexible layer, achieving effective shock absorption protection.

[0026] The electromechanical connections involved in this utility model are common practices used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments; they are common knowledge.

[0027] Components not described in detail in this article are existing technologies.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
