Description

Technical Field

[0001] The utility model relates to the field of heat exchanger products, in particular to a flow-enhancing staggered-tooth turbulent plate for an oil cooler. Background Art

[0002] Oil coolers have been widely used in gearboxes, hydraulic systems or vehicle engines. Their working principle is to circulate and cool the lubricating oil through convection heat exchange between the coolant side and the oil side, effectively controlling the oil temperature within a certain range, thereby ensuring the normal operation of the machinery.

[0003] At present, the automotive industry is developing in the direction of lightweighting, reducing fuel consumption, and energy conservation and emission reduction. As a result, the OEMs have increasingly compacted the layout space of the entire vehicle, and at the same time have increasingly higher requirements for the heat dissipation efficiency of the cooler. That is, the cooler needs to have a higher heat dissipation efficiency in the same space, or the cooler needs to have the same heat dissipation efficiency when the space becomes smaller. Utility Model Content

[0004] In order to solve the above problems, an oil cooler is provided with an enhanced flow-around staggered-tooth turbulent plate, which can enhance the flow-around effect and more upper and lower layer contact heat exchange, thereby improving the overall heat exchange capacity of the automobile thermal system.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A reinforcing staggered-tooth turbulent plate for an oil cooler comprises a plate body, wherein a first side surface of the plate body has a plurality of tooth rows, each tooth row comprises a plurality of first tooth monomers arranged at intervals and a plurality of second tooth monomers arranged at intervals, the first tooth monomers and the second tooth monomers are arranged alternately, and the end faces of adjacent first tooth monomers are in contact with or share a portion of the end faces of the adjacent second tooth monomers, so that the plurality of first tooth monomers and the plurality of tooth monomers are arranged alternately one by one;

[0007] The first tooth monomer and the second tooth monomer have the same structure and are both tooth monomers, and the tooth widths at two ends of the tooth monomer are different.

[0008] Preferably, the end of the tooth monomer is a trapezoidal structure.

[0009] Preferably, the end of the tooth monomer is an isosceles trapezoidal structure.

[0010] Preferably, the first tooth top width D1 of the first end of the tooth monomer, the first tooth bottom width D2 of the first end of the tooth monomer, the second tooth top width D3 of the second end of the tooth monomer, and the second tooth bottom width D4 of the second end of the tooth monomer meet the following conditions:

[0011] D3<D1<D2<D4.

[0012] Preferably, a plurality of the first tooth monomers form a first tooth monomer row, and the first tooth monomer row has a first symmetry plane; a plurality of the second tooth monomers form a second tooth monomer row, and the second tooth monomer row has a second symmetry plane;

[0013] The first symmetry plane and the second symmetry plane are parallel.

[0014] Preferably, the tooth row, and the first tooth monomers and the second tooth monomers in the tooth row are all formed by stamping a plate.

[0015] Preferably, in each of the tooth rows, surfaces of adjacent first tooth monomers and second tooth monomers are in continuous contact.

[0016] The beneficial effects of using the utility model are:

[0017] The oil cooler uses a staggered-tooth turbulent plate with enhanced flow around. Since multiple tooth units are arranged in the tooth row, and the surface of each tooth unit facing the fluid flow direction is a compound slope, when the oil or water passes through this area, the compound slope forces the oil and water to flow around and exchange heat in the upper and lower directions, thereby enhancing the heat exchange efficiency of the upper and lower layers.

[0029] In order to make the purpose, technical solution and advantages of the technical solution more clear, the technical solution is further described in detail below in conjunction with specific implementation methods. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the technical solution.

[0030] In order to solve the problem in the prior art that the cooler needs to have a higher heat dissipation efficiency in the same space or the cooler needs to have the same heat dissipation efficiency when the space becomes smaller, this embodiment proposes a reinforced flow-around staggered tooth turbulent plate for an oil cooler, such as Figure 1 As shown, the main body of the enhanced bypass staggered tooth turbulence plate for the oil cooler is a plate body, and the first side surface of the plate body has 6 tooth rows 1, each tooth row 1 has a plurality of first tooth monomers 11 and a plurality of second tooth monomers 12 arranged at intervals, the first tooth monomers 11 and the second tooth monomers 12 are arranged alternately, and the end faces of adjacent first tooth monomers 11 are in contact with or share part of the end faces of the adjacent second tooth monomers 12, so that a plurality of first tooth monomers 11 and a plurality of tooth monomers are arranged alternately one by one; the first tooth monomers 11 and the second tooth monomers 12 have the same structure and are both tooth monomers, and the tooth widths at the two ends of the tooth monomers are different, and at this time, the side surfaces of the tooth monomers form a compound inclined surface.

[0031] It can be understood that the above-mentioned first tooth monomer 11 and second tooth monomer 12 can be regarded as a first tooth monomer 11 formed after retaining a unit length in the tooth row 1, and then displaced in a first direction perpendicular to the overall extension direction of the tooth row 1, and the dislocation is maintained for a unit length, thereby forming a second tooth monomer 12. Then, at the end of the extension of the second tooth monomer 12, it is displaced in a second direction perpendicular to the overall extension direction of the tooth row 1, and the dislocation is maintained for a unit length, thereby forming the next first tooth monomer 11. The first direction and the second direction are opposite and both are parallel to the main extension direction of the plate body. This is repeated to form a structure as shown in FIG. Figure 1 The tooth row 1 shown in FIG. 1 and the first tooth monomer 11 and the second tooth monomer 12 in the tooth row 1 .

[0032] As a preferred example, Figure 2-Figure 4 As shown, the end of the tooth monomer is an isosceles trapezoidal structure. The first tooth top width D1 of the first end of the tooth monomer, the first tooth bottom width D2 of the first end of the tooth monomer, the second tooth top width D3 of the second end of the tooth monomer, and the second tooth bottom width D4 of the second end of the tooth monomer meet the following conditions: D3<D1<D2<D4.

[0033] like Figure 5 As shown, when four oil coolers are stacked with the main body of the reinforced staggered turbulent plate as the plate body, and a structural plate 2 is placed on the top, the plate body and the structural plate 2 form an assembly and four layers of channels are formed between the assemblies, wherein the first and third layers of channels are channels for water flow, and the second and fourth layers are channels for oil flow. The water and oil flow in opposite directions.

[0034] like Figure 6 As shown, both water and oil are fluids. Taking one of the fluids as an example, the fluid flows from one end of the oil cooler with enhanced flow around the staggered tooth turbulence plate to the other end, and its flow direction is the first flow direction F1, which is substantially perpendicular to the main extension direction of the tooth row 1.

[0035] like Figure 7 As shown, when the fluid flows through the tooth row 1, the flow direction of the fluid is the first flow direction F1. When the fluid contacts the above-mentioned composite slope, it is guided by the composite slope so that the fluid is roughly divided into two main flow directions, one part of the fluid is diverted and flows to the third flow direction F3F2 of the lower layer; the other part of the fluid is diverted and flows to the third flow direction of the upper layer. When oil or water passes through this area, the composite slope guidance forces the oil and water to circumvent and exchange heat in both the upper and lower directions, thereby enhancing the heat exchange efficiency of the upper and lower layers, further enhancing its circumference effect and more upper and lower layer contact heat exchange, so that the overall heat exchange capacity of the automobile thermal system is improved.

[0036] Preferably, the tooth row 1, and the first tooth monomers 11 and the second tooth monomers 12 in the tooth row 1 are all formed by stamping a plate, which is convenient to form, has a low manufacturing cost, and can be mass-produced.

[0037] The surfaces of the adjacent first tooth monomers 11 and the second tooth monomers 12 in each tooth row 1 are in continuous contact, thereby preventing fluid leakage and continuously guiding the fluid.

[0038] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present technical content. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of this patent.
