Description

Technical Field

[0001] The utility model relates to the technical field of oil coolers, in particular to a cooler bottom chip reinforcement plate structure. Background Art

[0002] In modern industrial production, oil coolers, as crucial heat exchange devices, are widely used in various machinery and equipment to cool lubricating oil and ensure proper operation. During operation, especially when subjected to impact loads, the stability and reliability of the oil cooler's structure are crucial. Lubricating oil enters the cooler through oil holes and flows through the various layers of the chipset, completing the cooling process. Because the oil passages are through-holes, sealed only by the bottom chip, the bottom chip's oil holes become the weakest link in the cooler's overall strength.

[0003] In practical applications, the thickness of the bottom chip is usually between 0.4-0.5 mm. Such a thickness is prone to deformation or even tearing when subjected to impact loads. To solve this problem, traditional cooler designs usually install a bottom chip reinforcement plate at the bottom chip oil hole to enhance the structural strength of the area. Figure 1 As shown, the existing bottom chip reinforcement plate structure is mostly a flat design. When subjected to a large impact load, this structure is still prone to deformation and damage at this location, thereby affecting the overall performance and life of the cooler. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a cooler bottom chip reinforcement plate structure, which solves the problem that the existing planar bottom chip reinforcement plate is easily deformed and damaged when subjected to a large impact load.

[0005] To achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions: a cooler bottom chip reinforcement plate structure, including a bottom chip reinforcement plate assembled on the bottom of the bottom chip, the bottom chip reinforcement plate including a plate body, a first support portion is formed at the circumferential edge of the plate body, the middle portion of the plate body is recessed downward to form a semicircular groove, the first support portion and the semicircular groove are continuously bent to form a first step and a blocking portion, the first step is in contact with the bottom chip reinforcement plate, and the blocking portion is inserted into the through hole of the bottom chip.

[0006] Preferably, the outer side of the blocking portion is recessed downward to form a second step that contacts the bottom surface of the bottom chip.

[0007] Preferably, the blocking portion and the second step are continuously transitioned via a connecting surface.

[0008] Preferably, the connecting surface is perpendicular to the horizontal line in the main view projection.

[0009] Preferably, the blocking portion is higher than the first step and the second step on a horizontal line.

[0010] Preferably, the top surfaces of the first step and the second step are located at the same horizontal plane, and both contact the lower bottom surface of the bottom chip.

[0011] Preferably, a second support portion is formed between the first step and the second step, and the bottom surface of the first support portion is higher than the bottom surface of the second support portion.

[0012] Preferably, the top of the second supporting portion is concave, and a gas-sealed cavity is formed between the first step and the second step.

[0013] Preferably, the height between the upper surfaces of the first step and the second step and the lower surfaces of the first support portion, the second support portion and the semicircular groove is 4.5-5 cm.

[0014] Beneficial effects of the present invention: By using a cooler bottom chip reinforcement plate structure provided by the present invention, the following technical effects are achieved compared with the prior art:

[0015] 1. The bottom chip reinforcement plate adopts a ring-shaped first and second step design, achieving multi-point support for the bottom chip reinforcement plate, greatly improving support stability. This multi-point design can effectively disperse impact loads, reduce local stress concentration, and thus reduce the risk of deformation at the bottom chip oil hole.

[0016] 2. When assembling the bottom chip reinforcement plate, the sealing portion can be embedded into the through hole of the bottom chip, effectively sealing the through hole. The close fit between the vertical connecting surface and the through hole significantly improves the sealing effect of the through hole, preventing lubricating oil leakage and ensuring the normal operation of the cooler.

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. As long as the effects of the present invention can be exerted, various changes can be made to the embodiments.

[0023] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process.

[0024] Reference Figure 2-3 A cooler bottom chip reinforcement plate structure according to this embodiment will be described.

[0025] The bottom chip reinforcement plate 2 is assembled on the bottom of the bottom chip 1. The bottom chip reinforcement plate 2 includes a plate body 29. A first support portion 21 is formed at the circumferential edge of the plate body 29. The first support portion 21 is fixed to the inner surface of the water tank, so that the bottom chip reinforcement plate 2 is tightly pressed against the bottom chip 1. The center of the plate body 29 is recessed downward to form a semicircular groove 22. The semicircular groove 22 is used to block the oil hole of the bottom chip 1, which is a through hole.

[0026] In one embodiment, the first support portion 21 and the semicircular groove 22 are continuously bent to form a first step 23 and a blocking portion 25. When the bottom chip reinforcement plate 2 is fixed to the bottom chip 1, the first step 23 contacts the bottom chip 1 to support the bottom chip 1, and the blocking portion 25 is inserted into the through hole of the bottom chip 1 to block the through hole of the bottom chip 1.

[0027] Furthermore, the outer side of the sealing portion 25 is recessed downward to form a second step 24 that contacts the bottom surface of the bottom chip 1. The second step 24 and the first step 23 contact the bottom chip 1 together, providing multi-point support for the bottom chip 1. It should be noted that the second step 24 contacts the bottom circumference of the through hole. In a top view projection, the first step 23 and the second step 24 are annular. The multi-point support of the bottom chip reinforcement plate can effectively disperse the impact load, reduce local stress concentration, and thus reduce the risk of deformation at the bottom chip oil hole.

[0028] Furthermore, a continuous transition is formed between the sealing portion 25 and the second step 24 via a connecting surface 26. In the front view projection, connecting surface 26 is perpendicular to the horizontal line. When the sealing portion 25 is inserted into the through-hole, connecting surface 26 contacts the inner wall of the through-hole. This vertical connecting surface and the through-hole form a tight fit, significantly improving the sealing effect of the through-hole, preventing lubricating oil leakage and ensuring the normal operation of the cooler.

[0029] It should be noted that the blocking portion 25 is higher than the first step 23 and the second step 24 on the horizontal line, so as to ensure that the blocking portion 25 can enter the through hole when the first step 23 and the second step 24 contact the bottom surface of the bottom chip 1 .

[0030] It should be further explained that the top surfaces of the first step 23 and the second step 24 are located on the same horizontal plane and are both fixed to the lower surface of the base chip 1. A second support portion 28 is formed between the first step 23 and the second step 24. The bottom surface of the first support portion 21 is higher than the bottom surface of the second support portion 28. The height between the upper surfaces of the first step 23 and the second step 24 and the lower surface of the first support portion 21 is 4.5-5 cm.

[0031] In actual use, the first support portion 21 is welded to the surface of a water tank, so that the bottom chip reinforcement plate 2 is pressed against the bottom chip 1 to support the bottom chip 1. The second support portion 28 is suspended above the water tank surface and is not welded to the water tank. This ensures the overall integrity of the bottom chip reinforcement plate 2 and prevents damage during welding that would reduce the overall strength of the bottom chip reinforcement plate 2.

[0032] The top of the second support portion 28 is recessed, and a gas-sealed cavity 27 is formed between the first step 23 and the second step 24. When the second support portion 28 cooperates with the first support portion 21 to press the bottom chip reinforcement plate 2 against the bottom chip 1, the first step 23 and the second step 24 press against the bottom surface of the bottom chip 1, forming a gas-sealed cavity 27.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
