Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic oil tanks, in particular to a heat dissipation hydraulic oil tank. Background Art

[0002] A hydraulic oil tank is a container used to store the oil required to ensure the operation of the hydraulic system. Every hydraulic system requires a hydraulic oil tank. The hydraulic oil tank not only stores oil, but also dissipates heat for the oil, precipitates impurities, and allows air in the oil to escape.

[0003] Since hydraulic oil needs to work continuously, when it flows back into the oil tank, it can only rely on the oil tank itself to dissipate heat. Although this method can reduce the temperature, it is not efficient, and the heat transfer to the outside is limited by its own structure. The heat dissipation hydraulic oil tank in the prior art uses a fan to dissipate heat from the surface of the oil tank, but the heat dissipation effect is not ideal, and the addition of heat dissipation equipment increases the cost and also leads to an increase in the failure rate. To this end, we propose a heat dissipation hydraulic oil tank. Utility Model Content

[0004] The utility model aims to provide a heat dissipation hydraulic oil tank, which has the advantages of good heat dissipation effect, energy saving and environmental protection without the need for additional equipment, and solves the problem of poor heat dissipation effect of the existing hydraulic oil tank.

[0006] The heat dissipation device comprises an internal heat sink installed inside the box body and in contact with the oil, and an external heat sink installed outside the box body and in contact with the air, the internal heat sink and the external heat sink are connected via a heat conducting plate, the internal heat sink comprises a plurality of parallel heat sinks, and the plurality of parallel heat sinks are fixed on the heat conducting plate, and gaps are provided between the heat sinks for the oil to flow;

[0007] The external heat sink comprises a plurality of parallel heat sinks, and the plurality of parallel heat sinks are fixedly connected by connecting plates, and gaps are provided between the heat sinks for air circulation and heat dissipation.

[0008] Preferably, the box body is provided with a first guide plate and a second guide plate which separate the return oil pipe and the suction oil pipe and are arranged in a staggered manner, an oil flow channel is formed between the first guide plate and the second guide plate, the internal heat sink is installed in the oil flow channel, and the installation direction of the internal heat sink is the same as the oil flow direction.

[0009] Preferably, the external heat sink is installed on the side of the box body, and the multiple heat sinks and the connecting plate of the external heat sink are in the same direction as the air circulation direction.

[0010] Preferably, a detachable filter residue net is connected to the opening of the oil return pipe, the oil return pipe is detachably installed, and the diameter of the installation opening is larger than the outer diameter of the filter residue net.

[0011] Preferably, the filter residue net includes a connecting pipe, an inclined pipe and a collecting pipe, the connecting pipe is connected to the opening of the oil return pipe, the connecting pipe and the collecting pipe are staggered and connected through the inclined pipe, the inclined pipe is used to filter impurities in the oil and transfer the impurities to the collecting pipe under the impact force of the oil and gravity, and the collecting pipe is used to collect impurities filtered out of the oil.

[0014] Preferably, an oil filter net for oil filling is arranged on the top of the box body, and a dust cover is arranged on the oil filter net.

[0015] Preferably, an air filter and a liquid level meter are also installed on the box.

[0016] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0017] 1. The utility model provides a heat dissipation device, wherein the internal heat sink of the heat dissipation device is directly arranged inside the oil tank, thereby increasing the contact area between the oil and the internal heat sink, and the external heat sink is arranged on the side of the oil tank. The oil tank is generally installed on a large machine or vehicle. When the vehicle is driving, air flows through the gap of the external heat sink to dissipate the heat of the external heat sink, and then dissipates the heat of the internal heat sink and the oil through the heat conduction plate. The installation direction of the internal heat sink is the same as the oil flow direction, and the installation direction of the external heat sink is the same as the vehicle travel direction, that is, the air flow direction, thereby maximizing the heat dissipation performance of the heat dissipation device.

The filter residue net adopts a three-stage structure. The connecting pipe is used for connection and disassembly, and the inclined pipe is used for filtering and transferring impurities to the collecting pipe, and the collecting pipe stores impurities. Since the connecting pipe and the collecting pipe are misaligned, the accumulated impurities are prevented from affecting the flow rate of the oil to a certain extent, and the oil is prevented from flushing the impurities in the collecting pipe. The inclined pipe can also allow impurities to enter the collecting pipe under the action of gravity and the flushing action of the oil. The filter residue net and the oil return pipe can be directly disassembled together, and then the filter residue net can be removed to clean up the impurities, which is convenient for cleaning and installation.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 As shown, a heat dissipation hydraulic oil tank comprises a box body 1, a return oil pipe 2 inserted into the box body 1 is installed on one side of the box body 1, and an oil suction pipe 3 inserted into the box body 1 is installed on the other side. A heat dissipation device is arranged inside the box body 1, and the heat dissipation device is located between the return oil pipe 2 and the oil suction pipe 3;

[0026] The heat dissipation device includes an internal heat sink 4 installed inside the box body 1 and in contact with the oil, and an external heat sink 6 installed outside the box body 1 and in contact with the air. The internal heat sink 4 and the external heat sink 6 are connected via a heat conducting plate 5. The internal heat sink 4 includes a plurality of parallel heat sinks, and the plurality of parallel heat sinks are fixed on the heat conducting plate 5. A gap is provided between the heat sinks for the oil to flow.

[0027] The external heat sink 6 includes a plurality of parallel heat sinks, and the plurality of parallel heat sinks are fixedly connected by connecting plates 7, and gaps are provided between the heat sinks for air circulation and heat dissipation.

[0028] The internal heat sink 4 of the heat dissipation device is directly arranged inside the box 1, increasing the contact area between the oil and the internal heat sink 4, and the external heat sink 6 is arranged on the side of the box 1. The box 1 is generally installed on a large machine or a vehicle. When the vehicle is running, air flows through the gap of the external heat sink 6 to dissipate the heat of the external heat sink 6, and then dissipates the heat of the internal heat sink 4 and the oil through the heat conduction plate 5.

[0029] like Figure 2 and 3 As shown, the box body 1 is provided with a first guide plate 8 and a second guide plate 9 which separate the return oil pipe 2 and the suction oil pipe 3 and are arranged in a staggered manner. An oil flow channel is formed between the first guide plate 8 and the second guide plate 9. An internal heat sink 4 is installed in the oil flow channel, and the installation direction of the internal heat sink 4 is the same as the oil flow direction.

[0030] The external heat sink 6 is installed on the side of the box body 1, and the multiple heat sinks and the connecting plate 7 of the external heat sink 6 are in the same direction as the air circulation direction. Since the installation direction of the internal heat sink 4 is the same as the oil circulation direction, the installation direction of the external heat sink 6 is the same as the vehicle travel direction, that is, the air circulation direction, the heat dissipation performance of the heat sink is increased to the greatest extent. The problem of poor heat dissipation effect of the existing hydraulic box body 1 is solved.

[0031] like Figure 1 and 4As shown, a detachable filter residue net 10 is connected to the opening of the oil return pipe 2. The oil return pipe 2 is detachably installed, and the diameter of the installation port is larger than the outer diameter of the filter residue net 10. The filter residue net 10 includes a connecting pipe 10a, an inclined pipe 10b and a collecting pipe 10c. The connecting pipe 10a is connected to the opening of the oil return pipe 2. The connecting pipe 10a and the collecting pipe 10c are staggered and connected through the inclined pipe 10b. The inclined pipe 10b is used to filter impurities in the oil and transfer the impurities to the collecting pipe 10c under the impact force of the oil and gravity. The collecting pipe 10c is used to collect impurities filtered out of the oil. The filter residue net 10 is directly connected to the oil return pipe 2 to prevent impurities from entering the oil tank, thereby reducing the burden of cleaning the oil tank. The filter residue net 10 adopts a three-stage structure. The connecting pipe 10a is used for connection and disassembly, the inclined pipe 10b is used for filtering and transferring impurities to the collecting pipe 10c, and the collecting pipe 10c stores impurities. Since the connecting pipe 10a is misaligned with the collecting pipe 10c, the accumulated impurities are prevented from affecting the flow rate of the oil to a certain extent, and the oil is prevented from flushing the impurities in the collecting pipe 10c. The inclined pipe 10b can also allow the impurities to enter the collecting pipe 10c under the action of gravity and the flushing action of the oil. The filter residue net 10 and the oil return pipe 2 can be directly disassembled together, and then the filter residue net 10 can be removed to clean up the impurities, which is convenient for cleaning and installation.

[0032] The top of the box body 1 adopts a sealed structure, the bottom of the box body 1 is a slope, and a drain valve 11 is provided at the bottom of the slope. A cleaning port 16 is provided on the side of the box body 1, and the cleaning port 16 is provided with a sealing cover. An oil filter 12 for oil filling is provided on the top of the box body 1, and a dust cover 13 is provided on the oil filter 12. A liquid level gauge 15 is also installed on the box body 1. The oil tank adopts a fully enclosed type, and a cleaning port 16 is opened from the side to avoid the previous oil tank from opening the top cover for cleaning. The disadvantage of this oil tank is that pollutants in the air and oil leaked from the system are often easily returned to the oil tank through the gap between the upper cover and the box body 1 due to the poor sealing of the upper cover, causing uninterrupted pollution. An air filter 14 and a liquid level gauge 15 are also installed on the box body 1. Since hydraulic oil always contains water, when the oil temperature is higher than a certain temperature, the water contained in the oil will evaporate into water vapor, and the air filter 14 will communicate with the inside of the oil tank with the atmosphere, thereby removing gas and avoiding malfunctions. The liquid level meter 15 is for conveniently observing the remaining amount of oil in the oil tank.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
