Description

Technical Field

[0001] This utility model relates to the field of cooler technology, specifically to an air cooler with an auxiliary circulating oil pump. Background Technology

[0002] In fields such as construction machinery, wind power generation, electrical equipment, and heavy vehicles, hydraulic or gear transmission systems generate a large amount of heat during operation. To ensure that the system operates within a suitable temperature range, an oil cooler must be used to forcibly cool the working medium (such as hydraulic oil).

[0003] Air coolers (also known as air compressors) are widely used in the aforementioned fields due to their simple structure, convenient installation, lack of need for an additional water source, and low maintenance costs. Their typical working principle is as follows: the system's main oil pump delivers high-temperature oil to the air cooler. The oil flows within the cooling core's channels, and a cooling fan drives air to flow across the core's surface. Forced convection heat transfer removes the heat from the oil, thus cooling it.

[0004] However, traditional air coolers have revealed significant technical shortcomings in practical applications, especially under the following specific operating conditions: Currently, when using coolers, the oil entering the cooler usually needs to be cooled. Even oils with low temperatures that do not require cooling are usually cooled, which affects the normal use of mechanical equipment. Utility Model Content

[0005] The purpose of this invention is to provide an air cooler with an auxiliary circulating oil pump to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an air cooler with an auxiliary circulating oil pump, comprising: Mounting base, motor pump set, filter, cooling system and temperature control valve; The motor pump unit is installed on the upper surface of the mounting base. The oil inlet of the motor pump unit is connected to an oil inlet pipe, and the oil outlet of the motor pump unit is connected to an oil outlet pipe. The oil outlet pipe is connected to the inlet of a temperature control valve, and the outlet of the temperature control valve is connected to a cooling branch pipe and an output branch pipe respectively. The filter is installed on the oil outlet pipe. The cooling system includes a hollow outer casing with openings on both sides. A cooling fan is installed on one side of the outer casing, and a dispersion pipe and a collection pipe are respectively arranged on the upper and lower sides of the other side opening of the outer casing. Finned tubes are evenly connected between the dispersion pipe and the collection pipe. The cooling branch pipe and the output branch pipe are respectively connected to the dispersion pipe and the collection pipe. The end of the collection pipe away from the output branch pipe is connected to the oil outlet.

[0007] Preferably, the motor-pump assembly includes a drive motor and a gear pump. The drive motor is fixedly mounted on the mounting base via a motor mount, and the rotor shaft of the drive motor is connected to the input shaft of the gear pump via a coupling.

[0008] Preferably, an overflow pipe is connected to the oil outlet pipe, and an overflow pressure valve is installed at the end of the overflow pipe.

[0009] Preferably, a pressure gauge is installed on the overflow pipe.

[0010] Preferably, the lower surface of the outer casing is connected to both sides of a support frame, and the bottom of the support frame is connected to the mounting base by bolts.

[0011] Preferably, the finned tube is a hollow tube with fins set on the outer wall, and the finned tube is made of aluminum or copper.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This solution incorporates a temperature control valve that divides the oil flowing through the cooling system into two paths. This allows the system to select the appropriate path based on the oil's temperature. High-temperature oil can be cooled normally, while low-temperature oil can flow through another path without cooling, ensuring the normal operation of the mechanical equipment.

[0013] In this scheme, the motor pump unit serves as an auxiliary circulating oil pump to provide power for the oil. During filtration, it can provide sufficient pressure to ensure filtration efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Therefore, they should not be construed as limitations on this utility model. Example

[0018] Please see Figure 1-3 This utility model provides a technical solution: an air cooler with an auxiliary circulating oil pump, comprising: a mounting base 1, a motor pump set, a filter 6, a cooling system and a temperature control valve 9; The motor pump unit is mounted on the upper surface of the mounting base 1. The oil inlet of the motor pump unit is connected to the oil inlet pipe 4, and the oil outlet of the motor pump unit is connected to the oil outlet pipe 5. The oil outlet pipe 5 is connected to the inlet of the temperature control valve 9. The outlet of the temperature control valve 9 is connected to the cooling branch pipe 10 and the output branch pipe 11 respectively. The filter 6 is installed on the pipeline of the oil outlet pipe 5. The cooling system includes a hollow outer casing 12 with openings on both sides. A cooling fan 13 is installed on one side opening of the outer casing 12. A dispersion pipe 14 and a collection pipe 15 are respectively arranged on the upper and lower sides of the other side opening of the outer casing 12. Finned tubes 16 are evenly connected between the dispersion pipe 14 and the collection pipe 15. The cooling branch pipe 10 and the output branch pipe 11 are connected to the dispersion pipe 14 and the collection pipe 15 respectively. The end of the collection pipe 15 away from the output branch pipe 11 is connected to the oil outlet 17.

[0019] Analysis of the above content: In use, the oil inlet pipe 4 is connected to the oil pipeline that needs to be filtered and cooled. The oil enters the motor pump unit through the oil inlet pipe 4 and is output through the oil outlet pipe 5. The oil is pressurized by the motor pump unit to obtain high-pressure oil. The high-pressure oil enters the filter 6 for filtration. The filtered oil reaches the temperature control valve 9 through the oil outlet pipe 5. The temperature control valve 9 is a valve with one inlet and two outlets. For the oil that needs to be cooled, it enters the dispersion pipe 14 from the cooling branch pipe 10. The oil enters the finned tube 16 from the dispersion pipe 14 and finally enters the collection pipe 15 for collection and is discharged from the oil outlet 17. During this process, the cooling fan 13 blows air to the finned tube 16 to dissipate heat from the finned tube 16 and the oil inside.

[0020] For oil that does not require cooling, it enters the collection pipe 15 from the output branch pipe 11 and is discharged from the oil outlet 17.

[0021] For example, a one-in-two-out temperature control valve is a three-way diverter type. Its core structure consists of one inlet (P, the air cooler port with an auxiliary circulating oil pump) and two outlets (A, the air cooler port with an auxiliary circulating oil pump, and B, the air cooler port with an auxiliary circulating oil pump). By adjusting the valve core position, the fluid distribution ratio between the two outlets is controlled, thus achieving precise temperature regulation. Depending on the driving method, for example, a self-operated one-in-two-out temperature control valve operates on the principle of automatically adjusting based on the thermal expansion and contraction characteristics of the temperature-sensitive liquid. When the medium temperature rises, the temperature-sensitive liquid expands, pushing the valve core to close the main channel, forcing the fluid to flow out through the bypass port; when the temperature decreases, the spring returns to its original position, opening the main channel. For example, the SENMI series of self-operated temperature control valves with auxiliary circulating oil pumps can achieve proportional regulation without external power. Typical models: TD-2 / TD-4 series of air coolers with auxiliary circulating oil pumps (such as TD-4L-150 air cooler with auxiliary circulating oil pump), suitable for hot water, hot oil and other media, with a diameter of DN15-DN150 and a pressure range of 0.6-6.4MPa. Materials can be cast iron or stainless steel. Example

[0022] Please see Figure 1-3 This utility model provides a technical solution based on Embodiment 1: the motor pump group includes a drive motor 2 and a gear pump 3. The drive motor 2 is fixedly mounted on the mounting base 1 through a motor seat. The rotor shaft of the drive motor 2 is connected to the input shaft of the gear pump 3 through a coupling.

[0023] Analysis of the above content: The rotor shaft of the drive motor 2 can drive the pump wheel of the gear pump 3 to rotate, and perform suction work. Example

[0024] Please see Figure 1-3 Based on Embodiment 1, this utility model provides a technical solution: an overflow pipe is connected to the oil outlet pipe 5, an overflow pressure valve 7 is installed at the end of the overflow pipe, and a pressure gauge 8 is installed on the overflow pipe.

[0025] Analysis of the above content: such as Figure 1 As shown, filter 6 is located downstream of overflow pressure valve 7 (that is, when the oil in oil outlet pipe 5 flows to filter 6, it will first pass through overflow pipe). When filter 6 is used for a longer period of time and gradually becomes clogged, resulting in a decrease in filtration effect, the oil pressure at overflow pipe increases, and oil is discharged from overflow pipe and overflow pressure valve 7. This can also remind the staff to clean or replace filter 6. Example

[0026] Please see Figure 1-3 Based on Embodiment 1, this utility model provides a technical solution: both sides of the lower surface of the outer casing 12 are connected to a support frame 18, and the bottom of the support frame 18 is connected to the mounting base 1 by bolts.

[0027] Analysis of the above content: The load-bearing frame 18 is made of stainless steel and provides stable support for the outer casing 12. Example
