Technical Field

[0001] This utility model relates to the field of coolers, and more particularly to a novel hydraulic transmission oil cooler. Background Technology

[0002] A hydraulic oil cooler is an industrial device primarily used in the circuits of hydraulic systems. Hydraulic oil coolers are commonly used in excavators, concrete pumps, fine slurry pumps, boom pumps, truck-mounted pumps, pile drivers, trenchers, rotary drilling rigs, pavers, trenchless equipment, air compressors, and road rollers as a force transmission medium.

[0003] During operation, hydraulic systems generate a large amount of heat due to the flow of hydraulic oil and friction of hydraulic components. Hydraulic oil coolers are used to cool the hydraulic oil.

[0004] However, when the cooler is in use, a water film will form on the surface of the cooler when the outside air temperature is high, resulting in condensation. This hinders heat transfer, reduces the cooler's heat dissipation efficiency, and causes corrosion to the cooler.

[0005] Therefore, it is necessary to provide a new type of hydraulic transmission oil cooler to solve the above-mentioned technical problems. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] First Embodiment

[0026] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A schematic diagram of the structure of the first embodiment of the novel hydraulic transmission oil cooler provided by this utility model; Figure 2 for Figure 1 The diagram shows a cross-sectional view of the protective sleeve. Figure 3 for Figure 2 The diagram shows the structure of the fixing device. The novel hydraulic transmission oil cooler includes: a cooling device 1, a protective device 2, and a fixing device 3.

[0027] The protective device 2 includes a protective sleeve 21, a filter element 22, a fan 23, two mounting rings 24, multiple heat dissipation slots 25, and multiple heat sinks 26. The two mounting rings 24 are fixedly mounted on the surface of the cooling device 1, the protective sleeve 21 is fixedly mounted on the surface of the mounting rings 24, the filter element 22 is disposed inside the protective sleeve 21, the fan 23 is fixedly mounted inside the protective sleeve 21, the multiple heat dissipation slots 25 are respectively opened inside the two mounting rings 24, and one side of each of the multiple heat sinks 26 is fixedly connected to the surface of the cooling device 1.

[0028] The fixing device 3 is disposed inside the protective sleeve 21, and the fixing device 3 is used to limit the position of the filter element 22.

[0029] The fan 23, together with the heat sink 25 and the heat sink 26, dissipates heat from the surface of the cooling device 1 to increase the cooling effect of the cooling device 1.

[0030] Multiple heat sinks 26 are used to increase the contact area between the heat sink and the air blown out by the fan 23, thereby increasing the heat dissipation effect.

[0031] The filter element 22 is a desiccant used to filter moisture from the air entering the protective sleeve 21.

[0032] The filter element 22 is made of activated carbon fiber, activated alumina, or fibrous moisture-absorbing material.

[0033] The fixing device 3 includes a fixing sleeve 31, a moving device 32, and a limiting ring 33. The surface of the limiting ring 33 is fixedly connected to the surface of the inner wall of the protective sleeve 21. The fixing sleeve 31 is threadedly connected to the inside of the protective sleeve 21. The moving device 32 is disposed on one side of the fixing sleeve 31.

[0034] The fixing sleeve 31, together with the limiting ring 33, limits the filter element 22.

[0035] The fixing sleeve 31 is a threaded sleeve, and the protective sleeve 21 has a thread inside that matches the fixing sleeve 31, which is used to facilitate the installation of the fixing sleeve 31, thereby limiting the position of the filter element 22 and facilitating its replacement later.

[0036] The moving device 32 is a ring handle, which is used to rotate the fixed sleeve 31.

[0037] The moving device 32 is a concave handle used to rotate the fixed sleeve 31.

[0038] When the filter element 22 needs to be replaced, the moving device 32 is rotated to one side, thereby causing the fixed sleeve 31 to rotate to one side inside the protective sleeve 21 and move to one side to separate, and then the filter element 22 can be removed.

[0039] Once the new filter element 22 is installed inside the protective sleeve 21, the filter element 22 can be easily replaced by installing the fixing sleeve 31.

[0040] The working principle of the novel hydraulic transmission oil cooler provided by this utility model is as follows:

[0041] When in use, after the fan 23 is turned on, the outside air is filtered and dehumidified by the filter element 22, and then blown by the fan 23 to the cooling device 1. The air enters through the heat dissipation slot 25 at one end, contacts the surface of the heat sink 26 to dissipate heat, and is then discharged through the heat dissipation slot 25 at the other end.

[0042] Compared with related technologies, the novel hydraulic transmission oil cooler provided by this utility model has the following beneficial effects:

[0043] This utility model provides a novel hydraulic transmission oil cooler. The fan 23, in conjunction with the heat dissipation slot 25 and heat dissipation fins 26, dissipates heat from the surface of the cooling device 1. At the same time, the filter element 22 filters and dehumidifies the air drawn in by the fan 23, thereby increasing the cooling effect of the cooling device 1 and preventing the formation of a water film and condensation on the surface of the cooling device 1.

[0044] Second Embodiment

[0045] Please refer to the following: Figure 4 and Figure 5 Based on the novel hydraulic transmission oil cooler provided in the first embodiment of this application, the second embodiment of this application proposes another novel hydraulic transmission oil cooler. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0046] Specifically, the difference in the novel hydraulic transmission oil cooler provided in the second embodiment of this application is that the top of the protective sleeve 21 of the novel hydraulic transmission oil cooler is provided with an installation sleeve 4, and an installation block 5 is fixedly connected to one side of the installation sleeve 4.

[0047] The protective cover 21 is divided into two halves, which is generally the protective cover 21 and the other half is the heat sink 26.

[0048] The surface of the mounting block 5 is slidably connected to a limiting sleeve 6, and a fixing element 7 is provided inside the limiting sleeve 6.

[0049] The fastener 7 is a bolt. The mounting block 5 and the limiting sleeve 6 both have threaded holes that are compatible with the bolt. After the bolt is installed into the threaded hole, the limiting sleeve 6 is limited.

[0050] The mounting block 5 is provided with a snap-fit ​​device 8 inside. The snap-fit ​​device 8 includes a slot 81 and a block 82. The slot 81 is opened inside the mounting block 5, and the block 82 is slidably connected to the inside of the slot 81.

[0051] Both sides of the protective sleeve 21 and the mounting sleeve 4 are fixedly connected to mounting blocks 5. Each of the four mounting blocks 5 has a slot 81 inside. Each slot 81 has a sliding block 82 inside. One side of each block 82 is fixedly connected to the inner wall of the two limiting sleeves 6. This is used to increase the limiting effect of the limiting sleeves 6 after the blocks 82 are inserted into the slots 81.

[0052] The working principle of the novel hydraulic transmission oil cooler provided by this utility model is as follows:

[0053] In use, after removing the fastener 7, the limiting sleeve 6 is pulled to one side, causing the two locking blocks 82 to move to one side and separate inside the two locking slots 81 respectively. Then, the mounting sleeve 4 is moved upward and removed, and the surface of the cooling device 1 can be inspected.

[0054] Compared with related technologies, the novel hydraulic transmission oil cooler provided by this utility model has the following beneficial effects:

[0055] This utility model provides a novel hydraulic transmission oil cooler. The mounting sleeve 4 is installed and disassembled by the mounting block 5 in conjunction with the limiting sleeve 6, the fixing part 7 and the snap-fit ​​device 8, thereby facilitating the inspection of the cooling device 1 inside the protective sleeve 21.
