[0031] Example 1:

[0032] Please see Figure 1-4 This utility model provides a technical solution: a dual-channel oil tank cooling and heat dissipation device for high-frequency hydraulic breakers, comprising:

[0033] The first heat dissipation channel includes a coil structure 1, the oil inlet end of which is connected to the hydraulic oil discharge main connector 110 on the hydraulic breaker 100, and the oil outlet end of which is connected to the oil inlet of the oil tank 200.

[0034] The second heat dissipation channel includes a radiator 2 and a fan 3. The hydraulic oil discharged from the breaker 100 flows into the oil tank 200 through the radiator 2. The fan 3 is arranged on the side of the radiator 2. A return channel is provided between the oil outlet of the oil tank 200 and the main connector 110 for hydraulic oil return on the breaker 100.

[0035] The coil structure 1, radiator 2, fan 3 and oil tank 200 are all installed on the excavator equipped with the hydraulic breaker 100.

[0036] The coil structure 1 is mounted on the coil base 4 of the excavator. Several support plates 5 are spaced apart on the coil base 4, and the support plates 5 abut against and support the inner and / or outer sides of the coil structure 1. This provides support and shaping for the coil structure 1, reduces the impact of external vibrations on the coil structure 1 during excavator and breaker 100 operation, and improves its service life and the stability of internal airflow.

[0037] The radiator 2 includes an outer frame 7 and a corrugated tube 8. The corrugated tube 8 is positioned inside the outer frame 7, and its end radiator connector 9 passes through and is assembled onto the outer frame 7. The radiator connector 9 is connected to the main connector 110 for hydraulic oil discharge or the oil inlet of the oil tank 200. The outer frame 7 includes several channel steels 10 with their ends fixed together. This improves the structural strength of the radiator 2 and the stability of the positioning of the corrugated tube 8.

[0038] The corrugated pipe 8 includes several straight pipes 11 and connecting pipes 12. The straight pipes 11 are arranged in parallel at intervals, and the ends of adjacent straight pipes 11 are connected by U-shaped connecting pipes 12, which are positioned on the outer frame 7. The arrangement of several straight pipes 11 and connecting pipes 12 forms a corrugated hydraulic oil cooling pipeline, thereby increasing the contact area between the corrugated pipe 8, which absorbs heat from the hydraulic oil, and the airflow discharged by the fan 3, thus improving the heat dissipation and cooling efficiency of the hydraulic oil.

[0039] The working principle of the dual-channel oil tank cooling and heat dissipation device applied to a high-frequency hydraulic breaker in this embodiment includes: the hydraulic oil flowing through the corresponding components in the hydraulic breaker 100 to complete the lubrication and cooling effect is pumped out by the main hydraulic oil discharge connector 110. Part of it flows into the coil structure 1, and after passing through the internal spiral channel, the heat is absorbed by the coil and naturally cooled by the external airflow, thus dissipating and cooling the hydraulic oil. The other part of the hydraulic oil flows through the radiator connector 9 and through the corrugated pipe 8. During this process, the airflow from the fan 3 blows onto the corrugated pipe 8 and efficiently cools the corrugated pipe 8 that has absorbed the heat of the hydraulic oil. The cooled hydraulic oil flows into the oil tank 200 and is supplied to the hydraulic breaker 100 through the return channel, realizing the cooling and circulation supply of hydraulic oil. The dual-channel heat dissipation structure composed of the coil structure 1, radiator 2 and fan 3 on the excavator can achieve efficient heat dissipation of the hydraulic oil circulating in the hydraulic breaker 100, so that the temperature of the hydraulic oil supplied to the hydraulic breaker 100 is controlled below 110℃, ensuring stable hydraulic oil performance and good effect.

[0040] Example 2:

[0041] Please see Figure 2 The figure shows a dual-channel oil tank cooling and heat dissipation device for a high-frequency hydraulic breaker provided in Embodiment 2 of this utility model. Based on the above embodiments, this embodiment further improves upon the following technical solution: A flow gap is left between the spiral tubes of adjacent layers in the coil structure 1, and several isolation pads 6 are spaced apart. This achieves isolation between the spiral tubes of each layer in the coil structure 1, preventing collisions and compression caused by external vibrations, further improving its service life and the effect of guiding and dissipating hydraulic oil. The isolation pads 6 can be made of high-temperature resistant and elastic materials such as rubber to meet the requirements of use under high-temperature conditions and to achieve structural buffering and stress relief.

[0042] Example 3:

[0043] Please see Figure 3 , 4 The figure shows a dual-channel oil tank cooling and heat dissipation device for a high-frequency hydraulic breaker provided in Embodiment 3 of this utility model. Based on the above embodiments, this embodiment further improves upon the following technical solution: several layers of straight pipes 11 are arranged front and rear, with adjacent layers of straight pipes 11 staggered vertically. This increases the contact time between the hydraulic oil and the corrugated pipe 8, thereby improving the heat dissipation effect.

[0044] In summary, due to the adoption of the above technical solution, the dual-channel oil tank cooling and heat dissipation device for high-frequency hydraulic breakers in this embodiment has the following advantages compared with the prior art:

[0045] The heat dissipation device of this utility model is used to cool the hydraulic oil flowing into the breaker. Through the dual-channel heat dissipation structure composed of the excavator's coil structure, radiator and fan, the hydraulic oil circulating in the breaker can be efficiently cooled, so that the temperature of the hydraulic oil supplied to the breaker is controlled below 110℃, ensuring stable hydraulic oil performance and good effect.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
