Technical Field

[0001] The utility model relates to the technical field of oil coolers, and particularly relates to an oil cooler with a protection component. Background Art

[0002] An oil cooler is a common oil cooling device used in hydraulic systems and lubrication systems, mainly used for cooling the engine lubricating oil or fuel of vehicles, construction machinery, ships, etc. During the use of machinery, the lubricating oil in each lubrication system relies on the power of the oil pump, passes through the hot side channel of the oil cooler, and transfers its own heat energy to the oil cooler. The cold air on the oil cooler takes away the heat through the cold side channel of the oil cooler, thereby realizing the cooling of the lubricating oil and reducing the temperature of the lubricating oil to the working temperature to ensure that the main engine can continuously operate normally. However, when the existing oil cooler is used in cooperation with an engineering vehicle, it is generally installed at the lower part of the engineering vehicle. During the driving process of the engineering vehicle, the oil cooler may be knocked due to the undulating road conditions, or may be impacted by foreign objects such as flying stones splashed, resulting in damage and rupture of the oil cooler. Therefore, improvement is needed. Content of the Utility Model

[0028] As Figures 1 to 9As shown in the figure, an oil cooler with a protection component includes a heat exchange device 10 and a heat dissipation device 20. A first heat exchange surface and a second heat exchange surface are respectively arranged on the front and rear sides of the heat exchange device 10. The heat dissipation device 20 is arranged on one side of the second heat exchange surface, and a protection frame 30 is arranged at the first heat exchange surface. By arranging the first heat exchange surface and the second heat exchange surface on the heat exchange device 10, it is convenient to install the heat dissipation device 20 and the protection frame 30 respectively. The heat exchange device 10 is dissipated heat by the heat dissipation device 20, and the heat exchange device 10 is protected from impact by the protection frame 30, thereby improving the service life of the oil cooler on the engineering vehicle.

[0029] The heat exchange device 10 includes a heat dissipation core 11, an upper oil tank 12 and a lower oil tank 13 respectively arranged on both sides of the heat dissipation core 11. A pressure relief oil tank 14 is arranged on the heat dissipation core 11, and a bypass valve seat 15 is arranged at the outlet of the pressure relief oil tank 14. The upper oil tank 12 and the lower oil tank 13 are connected to the pressure relief oil tank 14 through the bypass valve seat 15. In this embodiment, by arranging the upper oil tank 12 and the lower oil tank 13 on the opposite sides of the heat dissipation core 11 respectively, it is convenient for the lubricating oil to exchange heat energy with the heat dissipation core 11 through the upper oil tank 12 and the lower oil tank 13. At the same time, a bypass valve seat 15 and a pressure relief oil tank 14 are arranged at one end of the heat dissipation core 11. The pressure relief oil tank 14 is connected to the upper oil tank 12 and the lower oil tank 13 through the bypass valve seat 15. When the engineering vehicle runs for a long time, the temperature of the lubricating oil will also rise rapidly. At this time, when the high-temperature lubricating oil enters the upper oil tank 12 or the lower oil tank 13, the instantaneous pressure is relatively large. The existing heat exchange device 10 lacks a pressure relief oil tank 14, and it is very likely that the upper oil tank 12 or the lower oil tank 13 will burst under the instantaneous pressure, or the upper oil tank 12 or the lower oil tank 13 will produce a certain deformation under the instantaneous pressure, resulting in partial protrusion of the upper oil tank 12 or the lower oil tank 13, causing unsmooth oil return. Therefore, a pressure relief oil tank 14 and a bypass valve seat 15 are arranged on the heat dissipation core 11. When the pressure of the lubricating oil entering the upper oil tank 12 or the lower oil tank 13 is too high, part of the lubricating oil can enter the pressure relief oil tank 14 through the bypass valve seat 15 to relieve the instantaneous pressure of the lubricating oil, thereby avoiding problems such as bursting or deformation of the upper oil tank 12 or the lower oil tank 13, and improving the service life and use stability of the heat exchange device 10.

[0030] The bypass valve seat 15 includes a seat body, an oil inlet 16 and an oil outlet 17 respectively arranged on the upper and lower sides of the seat body. The oil inlet 16 and the oil outlet 17 are connected and located on the same axis to form an oil passage 151. One side of the seat body is provided with a pressure relief port 18 communicating with the pressure relief oil tank 14, and the pressure relief port 18 is communicated with the oil passage 151. In this embodiment, the seat body is connected to the upper oil tank 12 or the lower oil tank 13. The oil inlet 16 and the oil outlet 17 are arranged on the seat body. When the pressure range of the lubricating oil is within the normal threshold, the lubricating oil enters the seat body from the oil inlet 16 and flows out of the seat body from the oil outlet 17 into the upper oil tank 12 or the lower oil tank 13, thereby realizing the circulation of the lubricating oil. When the pressure range of the lubricating oil is greater than the normal threshold, some lubricating oil enters the pressure relief oil tank 14 through the pressure relief port 18 for pressure relief, and when the pressure range of the lubricating oil returns to the normal threshold again, it returns to the oil passage 151 through the pressure relief port 18 again, thereby realizing the return of the pressure-relieved lubricating oil.

[0031] Temperature control interfaces 19 communicating with the upper oil tank 12 or the lower oil tank 13 are arranged on both the upper oil tank 12 and the lower oil tank 13. In this embodiment, temperature control interfaces 19 are arranged in both the upper oil tank 12 and the lower oil tank 13. Temperature control devices can be installed through the temperature control interfaces 19, so as to facilitate collecting and controlling the temperature of the lubricating oil in the upper oil tank 12 and the lower oil tank 13, and it is convenient to adjust the output power of the heat dissipation device 20 according to the temperature control requirements.

[0032] An installation bracket is arranged on the heat exchange device 10. The heat dissipation device 20 is detachably installed on the second heat exchange surface through the installation bracket, and the protective frame 30 is detachably installed on the first heat exchange surface through the installation bracket. In this embodiment, by arranging the installation bracket on the heat exchange device 10, it is convenient to fix and lock the heat dissipation device 20 and the protective frame 30 through the installation bracket, and it is convenient to realize quick installation or disassembly.

[0033] A plurality of ventilation through holes 31 are evenly arranged on the protective frame 30. In this embodiment, a plurality of ventilation through holes 31 are arranged on the protective frame 30, so that external air can contact the heat dissipation core 11 through the ventilation through holes 31 arranged on the protective frame 30, thereby realizing the heat dissipation of the heat dissipation core 11. At the same time, due to the arrangement of the ventilation through holes 31, the air flow can be effectively improved, and thus the heat dissipation efficiency can be improved.

[0034] The heat dissipation device 20 includes a heat dissipation box 21 and a heat dissipation fan 22. A heat dissipation port is provided on one side of the heat dissipation box 21, and the heat dissipation port is in close contact with the second heat exchange surface. The heat dissipation fan 22 is arranged on the side of the heat dissipation box 21 opposite to the heat dissipation port; a heat dissipation space is provided in the heat dissipation box 21. The heat dissipation box 21 is rectangular in shape, and a heat dissipation guide plate 23 is provided in the heat dissipation space. The heat dissipation guide plate 23 is arranged along the diagonal direction of the heat dissipation box 21; the number of the heat dissipation fans 22 is two, and two fan mounting holes are provided on the heat dissipation box 21. The heat dissipation fans 22 are respectively arranged on the fan mounting holes; the fan mounting holes are respectively arranged on the upper and lower sides of the heat dissipation guide plate 23. In this embodiment, a heat dissipation guide plate 23 is provided in the heat dissipation box 21, and at the same time, fan mounting holes are respectively provided on the upper and lower sides of the heat dissipation guide plate 23 on the heat dissipation box 21. The heat dissipation fans 22 cooperate with the heat dissipation guide plate 23 to realize the guidance of the air flow in the heat dissipation space, avoid the interference of the air flow in the heat dissipation space, and thus improve the heat dissipation effect.

Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or direct / indirect application in other related technical fields shall be included in the patent protection scope of the present invention.
