A finned structure for an oil cooler

Abstract

This invention provides an oil cooler fin structure, including a fin body with two oil ports and two water ports located on the same straight line. The fin body also includes a local fin structure for increasing pressure at the oil and water ports. This local fin structure is composed of several first turbulence unit teeth, and the fin body is composed of several second turbulence unit teeth. The local fin structure is positioned between the two oil ports or the two water ports, increasing the pressure at the ports and allowing oil or water to seep into the lower surface of the fins. By modifying the local structure of the fins, this invention increases the pressure on the oil and water port sides, thereby guiding oil and water to the lower surface of the fins, ensuring uniform distribution of oil and water throughout the product, and improving the heat exchange efficiency.

Description

Technical Field

[0001] This invention relates to the field of oil cooler fin design, and more particularly to an oil cooler fin structure. Background Technology

[0002] Due to installation limitations, Figure 1 The common flow patterns in oil coolers are as follows: On the oil side of the fins, the oil only flows close to the upper surface of the fins (oil enters from one port but does not fully penetrate the lower surface of the oil fins before flowing out from another port), and the lower surface of the fins (low-speed zone) does not fully participate in heat exchange, resulting in a decrease in product performance; On the water side of the fins, the coolant only flows close to the upper surface of the fins (water enters from one port but does not fully penetrate the lower surface of the water fins before flowing out from another port), and the lower surface of the fins (low-speed zone) does not fully participate in heat exchange, resulting in a decrease in product performance.

[0003] Therefore, it is necessary to design a new oil cooler fin structure to overcome the above problems. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects of the prior art and provide an oil cooler fin structure that allows the low-speed zone to fully participate in heat exchange, thereby improving the heat exchange efficiency of the product and solving at least some of the problems in the prior art.

[0005] This invention is implemented as follows:

[0006] This invention provides an oil cooler fin structure, including a fin body with two oil ports and two water ports. The two oil ports and two water ports are located on the same straight line. The fin body is provided with a partial fin structure for increasing the pressure at the oil and water ports. The partial fin structure is composed of several first turbulence unit teeth, and the fin body is composed of several second turbulence unit teeth. The partial fin structure is located between the two oil ports or the two water ports, thereby increasing the pressure at the oil ports or water ports and allowing oil or water to seep into the lower surface of the fin.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] In the description of this invention, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0021] like Figures 1-4 , an embodiment of the present invention provides a fin structure for an oil cooler, which includes a fin body 1. Two oil ports 2 and two water ports 3 are opened on the fin body 1. The two oil ports 2 are located on the same straight line, and the two water ports 3 are located on the same straight line. A local fin structure 4 for increasing the pressure at the oil port or the water port is provided on the fin body 1. The local fin structure 4 is composed of several first turbulent flow unit teeth, and the fin body 1 is composed of several second turbulent flow unit teeth. The local fin structure 4 is arranged between two oil ports 2 or two water ports 2, so as to increase the pressure at the oil port 2 or the water port 3, and enable the engine oil or water to penetrate into the lower surface of the fin. The increase in pressure at the oil port or the water port enables the engine oil or water to flow through the oil port or the water port to the lower surface of the fin, making the oil and water evenly distributed throughout the product, improving the heat exchange efficiency of the product. In the traditional fin structure of the oil cooler, the engine oil or water only flows near the upper surface of the fin, and the heat exchange efficiency is not high.

[0022] In order to achieve the purpose of increasing the pressure at the oil port or the water port, the local fin structure 4 can be designed to have a different arrangement direction from that of the fin body 1, or the local fin structure 4 has different tooth shapes and tooth pitches from those of the fin body 1, thereby producing a certain obstructive effect on the flow of the engine oil or water, and increasing the pressure at the oil port or the water port. The fin structure of the oil cooler provided by the present invention can enable the low-speed area to fully participate in the heat exchange, improving the heat exchange efficiency of the product. It solves the problem that the oil flows out from another oil port without fully penetrating into the lower surface of the oil fin after entering from one oil port, or the problem that the water flows out from another water port without fully penetrating into the lower surface of the water fin after entering from one water port.

[0023] Embodiment 1, the arrangement direction of the first turbulent flow unit teeth is different from that of the second turbulent flow unit teeth (such as Figure 2 and Figure 4 ). The arrangement direction of the first turbulent flow unit teeth is perpendicular to that of the second turbulent flow unit teeth. For example, Figure 2 , the unit teeth of the local fin structure extend along the length direction of the entire fin, and the unit teeth of the fin body extend along the width direction of the entire fin. The local fin structure 4 has an obstructive effect on the engine oil or water flowing through here. In this embodiment, both the first turbulent flow unit teeth and the second turbulent flow unit teeth are rack bars with a "ji" - shaped cross-section, and both are connected to adjacent rack bars in a staggered connection structure. The first turbulent flow unit teeth and the second turbulent flow unit teeth are suitable for any tooth shape, not limited to the "ji" - shaped.

[0024] The tooth shapes and tooth pitches of the first turbulent flow unit teeth and the second turbulent flow unit teeth are different. Embodiment 2, for example, Figure 3 , the arrangement direction of the first turbulent flow unit teeth is the same as that of the second turbulent flow unit teeth, but the tooth shapes and tooth pitches are different; Embodiment 3, for example, Figure 4The arrangement direction of the teeth of the first turbulent unit is different from that of the teeth of the second turbulent unit, and the tooth shape and tooth pitch are also different.

[0025] The tooth pitch of the first turbulence unit tooth is smaller than that of the second turbulence unit tooth, and when the tooth is arranged more densely, the obstruction effect on oil and water is greater; the first turbulence unit tooth can be selected in various shapes, as long as it can achieve a better obstruction effect.

[0026] This invention also provides an oil cooler, comprising a plurality of oil cooler chips, which are stacked and welded together. Some oil cooler chips serve as oil channels, and some serve as water channels. A water channel is provided between two oil channels. Oil channel chips are provided with oil fins, and water channel chips are provided with water fins. The oil fins and water fins can play a turbulent flow role, allowing the oil and water to stay in their respective channels for a longer time, thereby enhancing the cooling effect of the water channels on both sides of the oil channel. Adjacent water channel chips are connected by a sealed medium channel that penetrates the water inlet of the oil fin, and adjacent oil channel chips are connected by a sealed medium channel that penetrates the oil inlet of the water fin.

[0027] When the partial fin structure 4 is located between two oil ports 2, the pressure at the oil ports is increased, allowing the oil to penetrate into the entire oil fin and flow throughout the oil fin, thus improving the heat exchange efficiency. When the partial fin structure 4 is located between two water ports 3, the pressure at the water ports is increased, allowing the water to penetrate into the entire water fin and flow throughout the water fin, thus increasing the residence time of the water in the water channel chip layer, thus improving the heat exchange efficiency.

[0028] Figure 2 This is the specific structural composition of the present invention, and... Figure 1 The difference lies in the modification of the local structure of the fins, which allows the lower surface of the fins (the side facing away from where oil or water enters the fins, i.e., the low-speed zone) to fully participate in heat exchange.

[0029] This invention modifies the local structure of the fins, increasing the local pressure on the oil and water sides, thereby guiding the oil and water into the entire product and improving the product's heat exchange efficiency.

[0030] Flow field analysis was performed on the improved oil cooler fin structure. This invention increases the pressure on the oil and water inlet side by modifying the local structure of the fins, thereby guiding oil and water to the lower surface of the fins, so that the oil and water are evenly distributed throughout the product, thus improving the heat exchange efficiency of the product.

[0031] The fin structure of this invention has a flow guiding function; therefore, the fins are not limited to the shapes and structures listed in this embodiment. The partial fin structure 4 and the fin body 1 can have different tooth shapes and pitches, such as… Figures 3-4 The local fin structure 4 can be various polygons, such as... Figures 3-4 All structures are acceptable.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. 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.
