Description
Technical Field
The invention relates to the technical field of cylinder liner cooling, in particular to a cylinder liner cooling device capable of accurately shunting.
Background
At present, with the continuous improvement of the explosion pressure and the power of an engine, more heat is generated when the high-power engine works, and in order to ensure that each system in an engine cylinder can reliably and coordinately work, the cylinder group of the engine needs to be subjected to cooling treatment, in particular to the upper middle part in a cylinder sleeve.
In the prior art, because the starting position of combustion in an engine cylinder is near the top dead center of a piston, more cooling water is needed at the upper part of a cylinder sleeve. However, most of the annular cylinder water jackets formed between the cylinder sleeve and the cylinder body are consistent in upper and lower channel sectional areas, and due to unreasonable water inlet and outlet shapes and position arrangement, excessive cooling liquid is distributed in the middle and lower parts of the cavity by cooling water, so that the sealing structure of the middle and upper parts of the cavity, the cylinder body and the cylinder sleeve cannot be effectively cooled.
In summary, how to provide a device for effectively cooling the cylinder body and the cylinder liner at the middle and upper parts of the cavity is a problem to be solved by those skilled in the art.
Disclosure of Invention
Therefore, the invention aims to provide the cylinder sleeve cooling device capable of precisely shunting, which can effectively cool the cylinder body and the cylinder sleeve at the middle and upper parts of the cavity, has a simple structure, is convenient to use, and can be popularized and used.
In order to achieve the above object, the present invention provides the following technical solutions:
A precisely split cylinder liner cooling apparatus, comprising: the cylinder body and the cylinder sleeve embedded in the cylinder body, wherein the outer peripheral wall of the upper part of the cylinder sleeve and the inner peripheral wall of the cylinder body form a circular cylinder upper water jacket, the outer peripheral wall of the middle part of the cylinder sleeve and the inner peripheral wall of the cylinder body form a circular cylinder upper water jacket and a circular cylinder lower water jacket, and the outer peripheral wall of the lower part of the cylinder sleeve and the inner peripheral wall of the cylinder body form a circular cylinder lower water jacket; the sectional area of the upper water jacket of the annular cylinder is larger than the sectional area of the upper water jacket and the lower water jacket of the annular cylinder and smaller than the sectional area of the lower water jacket of the annular cylinder;
The cylinder body is characterized in that a cylinder sleeve water inlet hole is formed in one side of the cylinder body, a cylinder sleeve upper water outlet hole is formed in the upper portion of the other side of the cylinder body, a cylinder sleeve lower water outlet hole is formed in the lower portion of the other side of the cylinder body, the cylinder sleeve water inlet hole and the cylinder sleeve upper water outlet hole are communicated with the cylinder sleeve upper water jacket, and the cylinder sleeve lower water outlet hole is communicated with the cylinder sleeve lower water jacket.
Preferably, a cylinder hole for accommodating the cylinder sleeve is formed in the center of the cylinder body, and sealing devices for sealing the upper end and the lower end of the cylinder body are respectively arranged at the upper end and the lower end of the cylinder sleeve.
Preferably, the sealing device comprises a supporting shoulder plane arranged at the upper end of the cylinder sleeve and used for compressing and sealing with the upper end of the cylinder body, and an O-shaped ring arranged at the lower end of the cylinder sleeve and used for axially sealing with the lower end of the cylinder body.
Preferably, the water inlet hole of the cylinder sleeve and the water outlet hole on the cylinder sleeve are obliquely opposite to the center of the cylinder, so that the flow speed of the cooling liquid flowing around the water jacket on the annular cylinder is improved.
Preferably, the cylinder body is provided with at least two cylinder holes, and an inter-cylinder balance water jacket is correspondingly arranged between the adjacent cylinder holes and is used for conducting heat generated by the cylinders in the working state to the cylinders in the adjacent non-working state.
Preferably, the cylinder body and the cylinder sleeve are waterproof materials.
When the cylinder sleeve cooling device with the accurate split flow is used, cooling liquid can enter the upper water jacket of the cylinder sleeve through the water inlet hole of the cylinder sleeve and flow along the upper water jacket of the cylinder sleeve, and finally most of the cooling liquid can flow out from the water outlet hole of the cylinder sleeve. And the cooling liquid can flow downwards under the action of self gravity, so that the middle part and the lower part of the cylinder sleeve are gradually cooled. The sectional area of the upper water jacket of the annular cylinder is smaller than that of the lower water jacket of the annular cylinder, so that the flow velocity of cooling liquid can be effectively improved, the purposes of rapidly cooling the upper part of the cylinder sleeve and taking away heat generated by combustion are achieved, and the working reliability of parts such as the cylinder sleeve, a piston and the like is ensured.
In addition, a part of cooling liquid can enter the lower water jacket of the annular cylinder through the upper water jacket and the lower water jacket of the annular cylinder, and the flow rate of the cooling liquid entering the lower water jacket of the annular cylinder can be effectively controlled due to the minimum sectional area of the upper water jacket and the lower water jacket of the annular cylinder. In addition, as the sectional area of the lower water jacket of the annular cylinder is the largest, the flow resistance of the cooling liquid can be effectively reduced, so that the cooling liquid entering the lower water jacket of the annular cylinder can effectively cool the lower part of the cylinder sleeve. Because the lower part of the cylinder body is provided with the cylinder sleeve lower water outlet hole, the cooling liquid entering the annular cylinder lower water jacket can finally flow out of the cylinder sleeve lower water outlet hole.
The smallest cross-sectional area means that the distance between the outer circumferential wall of the cylinder liner and the inner circumferential wall of the cylinder body is smallest, and this object can be achieved by thickening the thickness of the cylinder liner. The device realizes the accurate diversion of the cooling liquid by adjusting the thickness of the upper part, the middle part and the lower part of the cylinder sleeve and arranging two water outlets on the cylinder body, so that the upper part in the cylinder sleeve can obtain the most cooling liquid, and the heat dissipation of the upper part in the cylinder sleeve can be fully and effectively realized. The device can also ensure that a small amount of cooling liquid still exists to cool the middle lower part of the cylinder sleeve in the descending process of the piston.

All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The core of the invention is to provide a cylinder sleeve cooling device capable of precisely shunting, which can effectively cool a cylinder body and a cylinder sleeve at the middle upper part of a cavity, has a simple structure, is convenient to use, and can be popularized and used.
Referring to fig. 1 to 4, fig. 1 is a horizontal sectional view of a cylinder liner cooling device with precise split flow provided by the present invention; FIG. 2 is a longitudinal cross-sectional view of a precisely split liner cooling device; FIG. 3 is a transverse cross-sectional view of a precisely split liner cooling device; FIG. 4 is an oblique cut-away perspective view of a precisely split liner cooling device.
The invention provides a cylinder sleeve cooling device with accurate split flow, which comprises: the cylinder body 1 and the cylinder sleeve 2 embedded in the cylinder body 1, wherein the upper outer peripheral wall of the cylinder sleeve 2 and the inner peripheral wall of the cylinder body 1 form a circular cylinder upper water jacket 32, the middle outer peripheral wall of the cylinder sleeve 2 and the inner peripheral wall of the cylinder body 1 form a circular cylinder upper and lower water jacket 33, and the lower outer peripheral wall of the cylinder sleeve 2 and the inner peripheral wall of the cylinder body 1 form a circular cylinder lower water jacket 31; the sectional area of the upper water jacket 32 of the annular cylinder is larger than the sectional area of the upper water jacket 33 and the lower water jacket 33 of the annular cylinder and smaller than the sectional area of the lower water jacket 31 of the annular cylinder; the cylinder body 1 is provided with a cylinder liner water inlet hole 11 on one side, a cylinder liner upper water outlet hole 12 is arranged on the upper part of the other side of the cylinder body 1, a cylinder liner lower water outlet hole 13 is arranged on the lower part of the other side of the cylinder body, the cylinder liner water inlet hole 11 and the cylinder liner upper water outlet hole 12 are both communicated with a cylinder liner upper water jacket 32, and the cylinder liner lower water outlet hole 13 is communicated with a cylinder liner lower water jacket 31.
A cylinder jacket 3 for facilitating the flow of the coolant may be formed between the cylinder block 1 and the cylinder liner 2. The smallest sectional area of the cylinder jacket 3 means that the distance between the outer peripheral wall of the cylinder sleeve 2 and the inner peripheral wall of the cylinder body 1 is smallest, and the purpose can be achieved by thickening the thickness of the cylinder sleeve 2. The device realizes the accurate diversion of the cooling liquid by adjusting the thickness of the upper part, the middle part and the lower part of the cylinder sleeve 2 and arranging two water outlets on the cylinder body 1, so that the middle and upper parts of the cylinder sleeve 2 can be maximally cooled, and the heat dissipation of the middle and upper parts of the cylinder sleeve 2 can be fully and effectively realized. And the device can also ensure that a small amount of cooling liquid still exists in the descending process of the piston to cool the middle lower part of the cylinder sleeve 2. The device can not only meet the requirement of rapidly cooling the upper part of the cylinder sleeve 2, but also cool the lower part of the cylinder sleeve 2, and can realize the up-and-down layering and accurate flow control of cooling liquid, and the processing and manufacturing processes of the device are simple and convenient, and can be popularized and used.
It should be noted that, because the cross-sectional areas of the upper portion of the cylinder liner 2, the middle portion of the cylinder liner 2, and the lower portion of the cylinder liner 2 are different from the cylinder body 1, the upper portion, the middle portion, and the lower portion of the cylinder liner 2 need to be processed into structures with different thickness dimensions, so that the cylinder liner 2 can be integrally injection molded by using a mold during the manufacturing process, so as to simplify the installation operation of the precisely split cylinder liner cooling device.
The shape, the size, the structure, the material and the like of the cylinder body 1 and the cylinder sleeve 2 can be determined according to actual conditions and actual demands in the actual application process.
It should be further noted that, when the cylinder liner cooling device with accurate split flow provided by the invention is used, the cooling liquid can enter the upper water jacket 32 of the cylinder liner through the cylinder liner water inlet hole 11 and flow along the upper water jacket 32 of the cylinder liner, and finally most of the cooling liquid can flow out from the upper water outlet hole 12 of the cylinder liner. And the cooling liquid can flow downwards under the action of self gravity, so that the middle part and the lower part of the cylinder sleeve 2 are gradually cooled. Because the sectional area of the upper water jacket 32 of the annular cylinder is smaller than that of the lower water jacket 31 of the annular cylinder, the flow velocity of the cooling liquid can be effectively improved, the purposes of rapidly cooling the upper middle part of the cylinder sleeve 2 and taking away the heat generated by combustion are achieved, and the working reliability of the cylinder sleeve 2, the piston and other parts is ensured.
In addition, although the upper middle part of the cylinder liner 2 needs the most cooling liquid for heat dissipation, a small amount of cooling liquid is still needed in the descending process of the piston to effectively cool the lower middle part of the cylinder liner 2. In the process of using the device, part of cooling liquid can enter the annular cylinder lower water jacket 31 through the annular cylinder upper and lower water jacket 33, and the flow rate of the cooling liquid entering the annular cylinder lower water jacket 31 can be effectively controlled due to the smallest sectional area of the annular cylinder upper and lower water jacket 33. In addition, as the sectional area of the lower water jacket 31 of the annular cylinder is the largest, the flow resistance of the cooling liquid can be effectively reduced, so that the cooling liquid entering the lower water jacket 31 of the annular cylinder can effectively cool the lower part of the cylinder sleeve 2. And because the lower part of the cylinder body 1 is provided with the cylinder liner lower water outlet hole 13, the cooling liquid entering the annular cylinder lower water jacket 31 can finally flow out from the cylinder liner lower water outlet hole 13.
In summary, the cylinder liner cooling device with accurate split flow provided by the invention can effectively cool the cylinder body 1 and the cylinder liner 2 at the middle and upper parts of the cavity, and the device has a simple structure, is convenient to use, and can be popularized and used.
On the basis of the above embodiment, it is preferable that a cylinder hole for accommodating the cylinder liner 2 is provided at the center of the cylinder block 1, and sealing means for sealing with the upper and lower ends of the cylinder block 1 are provided at the upper and lower ends of the cylinder liner 2, respectively.
It should be noted that, a cylinder hole may be formed in the center of the cylinder body 1 in a penetrating manner, so that the cylinder liner 2 is inserted into the cylinder hole, and since the upper and lower ends of the cylinder liner 2 are respectively provided with a sealing device, the upper and lower ends of the cylinder liner 2 and the cylinder body 1 can be ensured to be sealed, and only a gap is left between the outer periphery of the cylinder liner 2 and the inner periphery of the cylinder body 1, so as to form an upper annular cylinder water jacket 32, an upper annular cylinder water jacket 33, and a lower annular cylinder water jacket 31, respectively, so as to ensure cooling and heat dissipation of the cooling liquid around the periphery of the cylinder liner 2.
The shape, the size, the structure and the like of the sealing device can be determined according to actual conditions and actual demands in the actual application process.
Preferably, the sealing device comprises a supporting shoulder plane arranged at the upper end of the cylinder sleeve 2 and used for tightly sealing with the upper end of the cylinder body 1 in a pressing mode, and an O-shaped ring 4 arranged at the lower end of the cylinder sleeve 2 and used for axially sealing with the lower end of the cylinder body 1.
It should be noted that, the cylinder hole provided by the cylinder body 1 may be a cylindrical hole, so that the cylinder liner 2 is placed in the cylinder hole, and the supporting shoulder plane is provided at the upper end of the cylinder liner 2, so that the compression sealing treatment can be effectively performed, so as to avoid liquid entering the cylinder liner 2. And be equipped with O type circle 4 at cylinder liner 2 lower extreme, mean that be equipped with O type circle 4 at cylinder liner 2 lower extreme periphery cover to guarantee that cylinder liner 2 lower extreme and cylinder body 1 fully realize axial seal, further guarantee that the coolant liquid is not from the upper and lower tip of cylinder liner 2 and cylinder body 1 contact, in order to guarantee that the coolant liquid all flows along ring jar upper water jacket 32, ring jar upper and lower water jacket 33 and ring jar lower water jacket 31, in order to fully cool off the heat dissipation to cylinder liner 2.
The shape, the size, the structure, the material and the like of the support shoulder plane and the O-shaped ring 4 can be determined according to actual conditions and actual demands in the actual application process.
On the basis of the above embodiment, it is preferable that the liner water inlet holes 11 and the liner upper water outlet holes 12 are both diagonally opposite to the center of the cylinder to increase the flow rate of the coolant flowing around the cylinder upper water jacket 32.
In this embodiment, the cylinder liner water inlet hole 11 and the cylinder liner water outlet hole 12 are all inclined to face the cylinder center, which means that the cylinder liner water inlet hole 11, the cylinder center and the cylinder liner water outlet hole 12 can be connected to form a straight line, and also can be understood as that the cylinder liner water inlet hole 11 and the cylinder liner water outlet hole 12 are respectively positioned at two ends of the diameter of the cylinder liner 2 on the same horizontal plane, so that the cooling liquid flowing into the cylinder body 1 from the cylinder liner water inlet hole 11 can be divided into two liquid flows along the cylinder liner water jacket 32 respectively, and the flowing distances of the two cooling liquids are equal due to the fact that the cylinder liner water outlet hole 12 is opposite to the cylinder liner water inlet hole 11, so that the flowing time of the cooling liquid flowing out of the cylinder liner water outlet hole 12 is the same, thereby effectively improving the flowing effect of the cooling liquid and shortening the flowing time.
In addition, the design of water inlet and outlet of the cylinder sleeve 2 which is obliquely opposite to the center of the cylinder can realize the purposes of enabling the cooling liquid to flow through the outer surface of the circular arc cylinder sleeve 2 in a tangential direction, reducing the flow resistance of the cooling liquid and the like, so that the cooling effect and the flow speed of the cooling liquid are effectively improved.
The shape, the size, the position and the like of the cylinder sleeve water inlet hole 11 and the cylinder sleeve water outlet hole 12 can be determined according to actual conditions and actual requirements in the actual application process.
Preferably, the cylinder body 1 is provided with at least two cylinder holes, and an inter-cylinder balance water jacket 34 is correspondingly arranged between the adjacent cylinder holes, and the inter-cylinder balance water jacket 34 is used for transmitting heat generated by the cylinders in the working state to the cylinders in the adjacent non-working state.
It should be noted that, the cylinder-to-cylinder balance water jackets 34 are correspondingly disposed between adjacent cylinder holes of the cylinder body 1, which may mean that a plurality of cylinder holes are disposed in the cylinder body 1, the cylinder liner 2 is respectively disposed in each cylinder hole, the cylinder body 1 structure between each adjacent cylinder hole is provided with a through hole structure in a penetrating manner, and the through hole structure is covered with the cylinder-to-cylinder balance water jackets 34, so that heat generated by a certain cylinder can be rapidly conducted into an adjacent cylinder without working through the cylinder-to-cylinder balance water jackets 34, so as to effectively reduce the thermal load of parts. Therefore, the inter-cylinder balance water jacket 34 is provided between the cylinder bores of the cylinder block 1, so that it is ensured that in the case where only one cylinder is operated or two adjacent cylinders are not combusted at the same time, if the coolant of one cylinder absorbs excessive heat while the coolant of the adjacent cylinder does not absorb more heat, the coolant can flow to the adjacent cylinder through the inter-cylinder balance water jacket 34 and conduct heat to the adjacent cylinder.
The size, position, structure, number and the like of the inter-cylinder balance water jackets 34 can be determined according to actual conditions and actual demands in the actual application process.
Preferably, the cylinder body 1 and the cylinder sleeve 2 are waterproof materials, so that the corrosion and rust phenomena caused by long-term contact between the cylinder body 1 and the cylinder sleeve 2 and cooling liquid can be effectively avoided, and the service effect and the service life of the device are improved.
