[0027] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0028] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0029] A plate-fin oil cooler provided by some embodiments of the utility model is described below in conjunction with the accompanying drawings.

[0030] Embodiment 1:

[0031] Combination Figure 1-Figure 3 As shown, the utility model provides a plate-fin oil cooler,

[0032] Specifically, it includes an outer shell 1, an oil inlet joint 2, an oil outlet joint 3, a plurality of fins 5 and a plurality of groups of partitions 6. The partitions 6 are mainly used to separate the plurality of fins 5 and facilitate the installation and protection of the fins 5. The plurality of fins 5 are arranged between the plurality of groups of partitions 6. Two groups of sealing plates 7 are symmetrically installed on the left and right sides of the interior of the outer shell 1. A holder 8 is embedded and installed inside the two groups of sealing plates 7. The holder 8 is mainly used to facilitate the opening of a mounting groove 10, and cooperates with the sealing plate 7 to fix the plurality of fins 5 and the plurality of groups of partitions 6 as a whole. A plurality of mounting grooves 10 are evenly opened on the inner side of the holder 8. The mounting groove 10 component is convenient for installing a compression adsorption airbag 9, and is convenient for the metal welding plate 11 to slide inside and limit and stabilize it. The interior of the plurality of mounting grooves 10 is installed with a compression adsorption airbag 9, and compression holes 12 are symmetrically opened in the middle of both sides of the compression adsorption airbag 9. Both ends of the plurality of fins 5 are connected to the outer side of the mounting groove 10 near the outer side of the mounting groove 10. The metal welding plate 11 and the connection between the metal welding plate 11 and the through hole 13 are penetrated by a through hole 13. An exhaust pipe 14 is provided on one side of the compression adsorption airbag 9, and the other side abuts the metal welding plate 11. The side of the metal welding plate 11 is slidably connected to the inside of the mounting groove 10. The compression holes 12 on both sides of the compression adsorption airbag 9 are respectively connected with the through hole 13 and the exhaust pipe 14. One end of the exhaust pipe 14 is installed through the base 8 and the sealing plate 7 and is connected to the outside, and the other end is connected to the compression adsorption airbag 9 through the compression hole 12. A filter block 15 is embedded in the inner side of the end of the exhaust pipe 14 that is connected to the outside. The filter block 15 mainly plays the role of filtering dust carried in the external air to improve the dustproof effect. The operation of the above-mentioned components enables the internal components of the cooler to be heated, especially the heat at the abutment between the fins 5 and the sealing plate 7 to be quickly dissipated, thereby reducing the damage to the connection caused by heat accumulation and improving durability.

[0033] Embodiment 2:

[0034] Combination Figure 2 and Figure 3 As shown, based on the first embodiment,

[0035] Specifically, the elastic buffering effect of the compression adsorption airbag 9 in the above embodiment 1 reduces the vibration effect of the connection between the fin 5 and the metal welding plate 11, improves the stability of the connection, and improves the overall use effect.

[0036] Combination Figure 2 As shown, in the above embodiment,

[0037] Specifically, multiple groups of partitions 6 are connected to the side ends of the holder 8, and seals 16 are embedded on the inner sides of the upper and lower ends of the connection between the outer shell 1 and the sealing plate 7. The seal 6 is mainly used to improve the sealing effect and prevent the oil from overflowing into the interior. The oil inlet connector 2 and the oil outlet connector 3 are symmetrically installed on the left end faces of the front and rear sides of the outer shell 1 respectively.

[0038] Combination Figure 1 and Figure 2 As shown, in the above embodiment,

[0039] Specifically, a mounting plate 4 is installed at the bottom of the outer shell 1. The mounting plate 4 is mainly used to facilitate the installation of the entire cold zone device. A plurality of mounting holes 17 are opened through the side end of the mounting plate 4. The mounting holes 17 are mainly fixed by external bolts to fix the entire cooler in one place.

[0040] The working principle and use process of the utility model: First, during use, when the oil inlet joint 2 and the oil outlet joint 3 exchange heat by passing the liquid through the channel inside 1, the oil cooler as a whole becomes hot and starts to dissipate heat, and the fins 5 and the metal welding plate 11 are heated, and due to the protection of the sealing plate 7, the heat is concentrated, and through the principle of thermal expansion and contraction, the fins 5 squeeze the metal welding plate 11 and squeeze the compression adsorption airbag 9, and the elasticity of the compression adsorption airbag 9 is compressed by force through the two compression holes 12, and the hot air and the external cold air are continuously sucked and discharged through the exhaust pipe 14 and the through hole 13, so as to achieve the heat dissipation effect and prevent the long-term accumulation of high temperature from causing damage to the connection. This not only improves the heat dissipation efficiency, but also improves the overall durability. Secondly, due to the above situation, the elastic effect of the compression adsorption airbag 9, the high temperature or vibration generated during use, the fins 5 are forced to squeeze the metal welding plate 11, and the vibration effect of the elastic reaction force of the compression adsorption airbag 9 is reduced to prevent the connection from breaking and falling off. This not only improves the stability of the connection, but also improves the overall use effect.

[0041] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
