Abstract
The utility model relates to a kind of cooling unit, be specially four-cylinder diesel engine cooling unit, be included in the cloth water jacket between diesel engine shell and four cylinder bodies, water pump water inlet is had between described cloth water jacket and diesel engine shell, water distribution has put four water inlets, respectively with the cavity connects outside four cylinder bodies, described water inlet is positioned at above cylinder body, in cloth water jacket, top cavity outside cylinder body is communicated with by tank with the lower cavity outside cylinder body, water port is also had between four described cylinder bodies are adjacent, for being communicated with the external cavity of adjacent cylinders, described cylinder body lower cavity is communicated with cylinder cap with drainage hole respectively by upper water hole with cylinder body lower cavity.This cooling unit ensures that the cavity outside each cylinder body can have current, and cooling water is evenly distributed, and cylinder body has good cooling effect everywhere.
Description
Technical field
The utility model relates to a kind of cooling unit, is specially four-cylinder diesel engine cooling unit.
Background technique
China is as traditional agriculture country, the supporting power of small-scale agricultural machinery mainly middle-size and small-size four-cylinder diesel engine, cylinder body is as the kernel component of diesel engine, determine the reliability of diesel engine, existing cylinder body cooling means is, water feeding of water pump directly to pump water the water jacket of cylinder body outside, easily causes each cylinder inhomogeneous cooling even from front end; In addition between adjacent cylinders due to stiffening rib, block the next cylinder body exocoel of current direction and supply water, cause four cylinder body inhomogeneous coolings even.In addition, cylinder deck does not have sand cleaning hole, and casting sand removal inconvenience, easily causes the problem such as scab in cylinder body, water hole blocking.
Model utility content
For above-mentioned technical problem, the utility model provides a kind of cooling uniform cooling device for diesel, and concrete technological scheme is:
Four-cylinder diesel engine cooling unit, be included in the cloth water jacket between diesel engine shell and four cylinder bodies, water pump water inlet is had between described cloth water jacket and diesel engine shell, water distribution has put four water inlets, respectively with the cavity connects outside four cylinder bodies, described water inlet is positioned at above cylinder body, in cloth water jacket, top cavity outside cylinder body is communicated with by tank with the lower cavity outside cylinder body, water port is also had between four described cylinder bodies are adjacent, for being communicated with the external cavity of adjacent cylinders, described cylinder body lower cavity is communicated with cylinder cap with drainage hole respectively by upper water hole with cylinder body lower cavity.
In described cloth water jacket, described outer wall of cylinder block and four-cylinder diesel engine support joint also have secondary water inlet.
The four-cylinder diesel engine cooling unit that the utility model provides, four water inlets that cooling water enters cloth water jacket enter the cavity outside four cylinder bodies respectively, ensure that the cavity outside each cylinder body can have current, top cavity simultaneously outside cylinder body communicates with the lower cavity outside cylinder body, also communicate between cylinder body is adjacent, ensure that cooling water is evenly distributed, ensure that cylinder body has good cooling effect everywhere, the water of the cavity outside four cylinder bodies enters cylinder cap by upper water hole and drainage hole and is beneficial to the higher problem of solution cylinder cover bottom surface heat load, reduces cylinder cap fault.Secondary water intake is also sand cleaning hole simultaneously, sand removal can reduce again processing boring, enhance productivity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is A-A schematic cross-section of the present utility model.
Embodiment
Accompanying drawings the utility model embodiment.
As depicted in figs. 1 and 2, four-cylinder diesel engine cooling unit, be included in the cloth water jacket 16 between diesel engine shell and four cylinder bodies 3, water pump water inlet 2 is had between described cloth water jacket 16 and diesel engine shell, cloth water jacket 16 there are four water inlets 1, respectively with the cavity connects outside four cylinder bodies 3, described water inlet 1 is positioned at above cylinder body 3, in cloth water jacket 16, top cavity outside cylinder body 3 is communicated with by tank 15 with the lower cavity outside cylinder body 3, water port 5 is also had between four described cylinder bodies 3 are adjacent, for being communicated with the external cavity of adjacent cylinders 3, described cylinder body 3 lower cavity is communicated with cylinder cap with drainage hole 14 respectively by upper water hole 13 with cylinder body 3 lower cavity.
In described cloth water jacket 16, described cylinder body 3 outer wall and four-cylinder diesel engine support joint also have secondary water inlet 11.
Water pump pumps into water from water pump water inlet 2, enters between cloth water jacket 16 and diesel engine shell, and then water enters the cavity four cylinder bodies 3 more respectively from four water inlets 1, ascending from hole, four water inlets 1, ensures that the cavity water supply flow outside each cylinder body 3 is equal; The water of the top cavity outside cylinder body 3 enters the lower cavity outside cylinder body 3 by tank 15; Simultaneously cylinder body 3 adjacent between cylinder bolt lug stiffening rib 4 on water port 5 ensure that the current between each cylinder body communicate; The water of the cavity outside four cylinder bodies 3 enters cylinder cap by upper water hole 13 and drainage hole 14.Secondary water intake 11 can ensure that the cavity outside cylinder body 3 does not stop by casting connection part to be affected, and ensures that the whole outer wall of cylinder block of cylinder body 3 can touch water.Secondary water intake 11 is also sand cleaning hole simultaneously, sand removal can reduce again processing boring.
