Abstract
The present invention provides a kind of machine body water cavity arrangement form, including main inlet opening and multiple branch inlet openings, the quantity of the multiple inlet opening is more than the quantity of the cylinder, the main inlet opening and the multiple branch inlet opening are in fluid communication, it is characterized in that, the cross-sectional area of the multiple inlet opening is not exactly the same.By above-mentioned setting, meet each cylinder flow uniformity, the cooling of each cylinder also becomes uniformly, to avoid the presence of slough accordingly, and fuse avoids cantilever, is conducive to the intensity for enhancing sand core.
Description
Technical field
The present invention relates to a kind of engine-cooling systems, it particularly relates to a kind of engine cloth water chamber.
Background technique
In diesel body structure, the requirement of limitation due to structure and complete machine arrangement, the presence or absence of water jacket cloth water chamber and
Arrangement is not quite similar.Ordinary circumstance before water jacket, designs one section of cloth water chamber, Neng Gouwen if space allows
Pressure, makes cooling water individually enter each cylinder.The cloth water chamber arrangement of the prior art is usually one inlet opening of every cylinder, as shown in Figure 1.
For the scheme of this every one inlet opening of cylinder, since existing cylinder cap is largely integrated cylinder cover, with four
For cylinder machine, four cylinders, one inlet opening, generally in the front end of cylinder cap.In this way, the water of 1,2 cylinders by body, cylinder cap into
Water hole path is shorter than the water route of 3,4 cylinders, that is, resistance is smaller.So most water can flow to 1,2 cylinders.Cause each cylinder stream
Amount is unevenly distributed, and the cooling of each cylinder is also just uneven.Solve the problems, such as that the machine that this also has will use water hole throttling on cylinder pad
Mode, i.e., throttle at the water hole of body upper cylinder cover, the setting of the water holes of 1,2 cylinders it is smaller, artificial gives 1,2 cylinder machines
Resistance is arranged in the water of body upper cylinder cover, but will increase the pressure drop of body, cylinder cover water jacket in this way, and the matching strip of feed pump is next difficult,
In order to meet pressure drop, need to match the water pump of bigger ability.
The end of cloth water chamber is generally for uniform wall thickness, and the side of inlet opening can not be made into the form of water cavity, this portion yet
Point water is due in the end of cloth water chamber, and not into the water hole of each cylinder water cavity, so will form slough, and water region in this section
It can not flow.Cloth water chamber and each cylinder water cavity are made into a fuse, have the presence of sand core cantilever phenomenon.
Summary of the invention
The cylinder uniformity for solving water flow the purpose of the invention is to available engine cloth water chamber is bad, and cloth water chamber has extremely
Pool exists, and sand core has the defect of cantilever.
The purpose of the present invention is what is be achieved through the following technical solutions.
A kind of machine body water cavity arrangement form, including main inlet opening and multiple branch inlet openings, the multiple branch inlet opening
For providing the cooling to engine cylinder, the main inlet opening and the multiple branch inlet opening are in fluid communication, the multiple
The quantity of inlet opening is more than the quantity of the cylinder, and the main inlet opening and the multiple branch inlet opening are in fluid communication, special
Sign is that the cross-sectional area of the multiple inlet opening is not exactly the same.
The present invention has the advantages that
1, cloth water chamber meets each cylinder flow uniformity into the different scheme of the water inlet hole number of each cylinder and section,
The cooling of each cylinder also becomes uniform accordingly.
2, water distribution cavity rear end, which increases an inlet opening, makes cloth water chamber end water energy enough flow, and avoids depositing for slough
?.
3, machine body water cavity core is made into monoblock type, and each cylinder water jacket and cloth water chamber are made into a fuse, and cloth water chamber end is because more
, there is support in one inlet opening, and fuse avoids cantilever, is conducive to the intensity for enhancing sand core.
Detailed description of the invention
By reading the following detailed description of the preferred embodiment, various other advantages and benefits are common for this field
Technical staff will become clear.The drawings are only for the purpose of illustrating a preferred embodiment, and is not considered as to the present invention
Limitation.And throughout the drawings, the same reference numbers will be used to refer to the same parts.In the accompanying drawings:
Attached drawing 1,2 shows water distribution cavity configuration in the prior art.
Attached drawing 3,4 shows a kind of water distribution cavity configuration of the invention.
Specific embodiment
The illustrative embodiments of the disclosure are more fully described below with reference to accompanying drawings.Although showing this public affairs in attached drawing
The illustrative embodiments opened, it being understood, however, that may be realized in various forms the disclosure without the reality that should be illustrated here
The mode of applying is limited.It is to be able to thoroughly understand the disclosure on the contrary, providing these embodiments, and can be by this public affairs
The range opened is fully disclosed to those skilled in the art.
Embodiment according to the present invention proposes that a kind of machine body water cavity arrangement form, the cooling system include main inlet opening
10, in first to fourth inlet opening 11-14 and the communicating pipe 15 of intaking.Wherein water is flowed into from main inlet opening, via runner pipe point
It Jin Ru not first to fourth inlet opening.Unlike the prior art, inlet opening of the invention is not fully consistent, specific next
Say, the area of the first inlet opening 11 and the second inlet opening 12 is smaller, and the area of third inlet opening 13 is larger, and first to third into
The quantity in water hole is one.The quantity of 4th inlet opening 14 is two, and one of area is larger, another area is smaller.
Preferably, which is an integral structure.
It is calculated by CFD, the cylinder uniformity of water flow of the present invention is met, and each cylinder is cooling uniformly, and cloth water chamber is not also deposited
In slough.
By the trial-production of blank, casting manufacturability of the invention is good, and the intensity of sand core is good.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
In the technical scope disclosed by the present invention, any changes or substitutions that can be easily thought of by anyone skilled in the art,
It should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention answers the protection model with claim
Subject to enclosing.
