Description

Technical Field

[0001] The utility model relates to a high-efficiency tube-fin plate type oil radiator, belonging to the technical field of oil radiators. Background Art

[0002] The oil radiator can ensure that the engine oil temperature is in an optimal temperature range, and play a role in lubricating and cooling each movement of the engine. When working, the cooling air flows through the heat dissipation belt, and the heat exchange principle is used to cool the high-temperature oil in the heat dissipation pipe to the ideal temperature range.

[0003] The internal oil circulation channel of the traditional plate-fin oil radiator is welded as a whole by the tube sheet (stamped by two dies) sandwiching the inner fin. Its pressure resistance is determined by many factors such as tube sheet thickness, sheet strength, welding rate, welding quality, die precision, assembly precision, etc., so the quality stability of the plate-fin oil radiator is restricted by many factors, and its pressure resistance is correspondingly reduced.

[0004] Traditional plate-fin oil coolers assemble internal fins through brazing to increase the heat transfer area, and the oil flow channel has an S-shaped structure, which has the problem of large flow resistance.

[0005] Traditional plate-fin oil coolers have many parts and require multiple sets of special molds, which makes the product design inflexible and the manufacturing cycle long. It is difficult to design and produce new products according to customer needs in a shorter period of time.

[0006] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0010] The heat dissipation pipe comprises a flat tube body, a plurality of flow channels are arranged inside the tube body, rib plates are arranged between adjacent flow channels, fins are arranged on the inner wall of the tube body, the fins are distributed in each flow channel, and the fins in adjacent flow channels are arranged in a staggered manner.

[0011] Furthermore, the pads are distributed on the left and right sides of the heat dissipation belt, and the pads are flush with the ends of the heat dissipation pipes along the length direction.

[0012] Furthermore, the end plate seals the end of the heat dissipation pipe, and the upper and lower ends of the end plate are respectively plugged and fixed to the upper mounting plate and the lower mounting plate.

[0013] Furthermore, the flow channel is arranged to penetrate along the length direction of the tube body.

[0014] Furthermore, the rib plate is arranged at an angle to the inner wall of the tube body.

[0015] Furthermore, the heat dissipation pipe is an integrated structure, and the pipe body, rib plate and fins are integrally extruded by a mold.

[0016] Furthermore, the upper mounting plate is provided with two circular mounting holes which are symmetrically arranged on the left and right sides, and an oil inlet screw seat and an oil return screw seat are installed in the two circular mounting holes.

[0017] Furthermore, two circular mounting holes are provided on the uppermost heat dissipation pipe near its two ends, and the circular mounting holes of the heat dissipation pipe correspond to the circular mounting holes on the upper mounting plate.

[0031] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.

[0032] like Figure 1-Figure 6 As shown together, the utility model provides a high-efficiency tube-fin plate type oil radiator, comprising an upper mounting plate 2 and a lower mounting plate 3 symmetrically arranged in the vertical direction, a plurality of heat dissipation tubes 1 stacked in the vertical direction are installed between the upper mounting plate 2 and the lower mounting plate 3, a heat dissipation belt 4 and a pad 5 are installed between adjacent heat dissipation tubes 1, and end plates 6 are fixedly connected to both ends of the heat dissipation tube 1 along the length direction.

[0033] The pads 5 are distributed on the left and right sides of the heat dissipation belt 4 , and the pads 5 are flush with the ends of the heat dissipation tubes 1 along the length direction.

[0034] The end plate 6 is used to seal the end of the heat dissipation tube 1 , and the upper and lower ends of the end plate 6 are respectively plugged and fixed to the upper mounting plate 2 and the lower mounting plate 3 .

[0035] The upper mounting plate 2 is provided with two circular mounting holes which are symmetrically arranged on the left and right sides, and an oil inlet screw seat 7 and an oil return screw seat 8 are installed in the two circular mounting holes.

[0036] The heat dissipation tube 1 comprises a flat tube body 11 , wherein a plurality of flow channels 12 are arranged inside the tube body 11 , and the flow channels 12 are arranged to penetrate along the length direction of the tube body 11 , and rib plates 13 are arranged between adjacent flow channels 12 , and the rib plates 13 are arranged at an angle to the inner wall of the tube body 11 .

[0037] The inner wall of the tube body 11 is provided with fins 14 , which are distributed in each flow channel 12 , and the fins 14 in adjacent flow channels 12 are arranged in a staggered manner.

[0038] The contact area between the heat dissipation pipe 1 and the hydraulic oil is increased by the fins 14 to improve the heat conduction efficiency, and the flow cross section is unobstructed, thereby reducing the flow resistance.

[0039] The heat dissipation pipe 1 is an integrated structure, and the pipe body 11, the rib plate 13 and the fin 14 are integrally extruded and formed by a mold, and the overall quality is stable and reliable.

[0040] Two circular mounting holes are provided near the two ends of the top heat dissipation tube 1. The circular mounting holes of the heat dissipation tube 1 correspond to the circular mounting holes on the upper mounting plate 2 and are used to install the oil inlet screw seat 7 and the oil return screw seat 8.

[0041] The specific working principle of this utility model:

[0042] The gear pump allows the hydraulic oil to enter each heat dissipation tube 1 through the oil inlet screw seat 7. While the hydraulic oil flows in each heat dissipation tube 1, it is fully cooled by heat exchange with the air through the tube wall. The cooled hydraulic oil is output to the radiator through the oil return screw seat 8.
