Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of heat exchanger equipment, specifically to a Z-shaped fin for an oil cooler. Background Technology
[0002] Oil coolers are a common type of oil cooling equipment used in hydraulic and lubrication systems. This equipment allows heat exchange between two fluid media with a certain temperature difference, thereby reducing oil temperature and ensuring normal system operation. Finned heat exchangers are the most widely used type of gas-liquid heat exchanger. Specifically, a finned heat exchanger consists of multiple rows of finned heat dissipation tubes arranged in a regular pattern. These finned heat dissipation tubes are made by adding spiral fins to ordinary heat dissipation base tubes. The spiral fins enhance heat transfer and exchange. Generally, the base tube can be made of steel, stainless steel, or copper, while the fins can be made of steel strips, stainless steel strips, copper strips, or aluminum strips. Currently, the heat dissipation fins used in automotive oil coolers are all H-type or Z-type. However, with the increasing demand for lightweight products in modern automobiles, traditional H-type or Z-type fins are large, heavy, and have low heat dissipation efficiency, failing to meet the needs of the automotive industry.
[0003] This case arose in order to resolve the aforementioned issues. Utility Model Content

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0019] like Figure 1-3As shown: A Z-shaped fin for an oil cooler includes a base plate 1, a top plate 2, and Z-shaped fins 3. The base plate 1 has Z-shaped fins 3 and a connecting plate 5. The bottom surface of the connecting plate 5 has a clip and a groove, and the Z-shaped fins 3 are connected in the clip and groove. Multiple holes 6 are opened on both sides of the base plate 1. The bottom surface of the connecting plate 5 has a limiting structure, which includes a connecting post 4, a fixing head 8, a limiting post 9, a spring 10, and a limiting ball 11. The limiting post 9 is located inside the connecting post 4. When connecting the base plate 1 and the connecting plate 5, the connecting post 4 on the connecting plate 5 is aligned with the hole 6 and inserted. When the fixing head 8 is completely located in the limiting groove 12, the protrusion 7 is pulled upward, causing the connecting post 4 to move upward. At this time, the spring... When the spring 10 contracts, the limiting ball 11 is pushed outward by the inclined surface of the fixed head 8 as it moves upward. At this time, part of the limiting ball 11 is pushed out of the empty groove and resists the inner wall of the limiting groove 12. At the same time, it also fixes and limits the connecting column 4, thus completing the fixation. When separating, simply press down on the protrusion 7 to drive the connecting column 4 to move down as a whole, so that the limiting ball 11 returns to the empty groove of the connecting column 4. Then pull the entire connecting plate 5 upward. Through the fixed splicing between multiple connecting plates 5, the heat flow can contact more volumes of the Z-shaped fins 3 at the same time. The "Z" shape of the Z-shaped fins 3 can achieve the advantage of more contact area under the same size, thus better realizing heat exchange and cooling.
[0020] Holes 6 are provided on the top surfaces of the base plate 1 and the connecting plate 5. The holes 6 between each pair of adjacent connecting plates 5 are staggered to achieve fixation between each layer. One end of the connecting column 4 protrudes from the connecting plate 5. A protrusion 7 is provided at the end of the connecting column 4 that protrudes from the connecting plate 5. A spring 10 is wrapped around the limiting column 9. The limiting column 9 is slidably connected to the inner wall of the connecting column 4.
[0021] One end of the spring 10 is fixedly connected to the lower part of the protrusion 7, and the other end of the spring 10 is fixedly connected to the inner wall of the connecting post 4. A fixing head 8 is fixedly connected to the top of the connecting post 4.
[0022] The fixing head 8 is a frustum shape with a smaller top and a larger bottom. The connecting column 4 has slots on both sides corresponding to the position of the fixing head 8. A limiting ball 11 is provided in the slot. When the fixing head 8 moves upward, the position where its inclined surface abuts against the limiting ball 11 gradually increases, thereby pushing the limiting ball 11 outward.
[0023] The hole 6 is provided with a limiting groove 12. The limiting groove 12 is a frustum shape with a smaller top and a larger bottom. When the limiting ball 11 abuts against the inclined inner wall of the limiting groove 12, it can be locked and abutted against the limiting groove 12 to fix the plates together.
[0024] The above-described embodiments are for illustrative purposes. Based on the above description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this utility model is not limited to the contents of the specification; its protection scope must be determined according to the claims.
