Abstract
The invention relates to an engine cooling circulation device. The technical scheme is that: the engine cooling circulation device comprises a water pump, wherein the water pump is communicated with a cylinder cover cooling circulation liquid inlet and a cylinder body cooling circulation liquid inlet respectively through pipelines; a cylinder body cooling circulation outlet and a cylinder cover cooling circulation liquid outlet are communicated and converged through a pipeline and then are connected with a cooler; the cooler is connected with a thermostat through a pipeline; the thermostat is connected with a radiator through a pipeline; the radiator is connected with the water pump through a pipeline; and the thermostat is directly connected with the water pump through a pipeline. The engine cooling circulation device has the advantages that the device is convenient to install and has a compact structure and a few fault points, and a cooling liquid circulation interface does not exist between a cylinder body and a cylinder cover.
Description
Technical field
The present invention is a kind of engine cooling circulation means.
Background technique
At present general diesel engine cooling system endless form is directly to link to each other through the sealing gasket between it between the cylinder block and head; And for guaranteeing fully cooling; Having a plurality of mouths of a river between the cylinder block and head links to each other; Material and manufacturing dimension requirement to sealing gasket are very high, and manufacture cost is high, and can increase the engine coolant disclosure risk.
Summary of the invention
The present invention is directed to the deficiency of existing technology, and the technological scheme that does not have liquid circulation interface, engine cooling circulation means that the fault point is few between a kind of easy for installation, compact structure, the cylinder block and head is provided.
The present invention realizes through following technical measures: a kind of engine cooling circulation means; Comprise water pump; Said water pump is communicated with the import of cylinder head cooling circulation liquid, the import of cylinder block cooling circulation liquid respectively through pipeline; Said cylinder block cooling circulation liquid outlet converges the back with the outlet of cylinder head cooling circulation liquid through pipeline connection and is connected with cooler; Said cooler is connected with thermostat through pipeline, and said thermostat is connected with radiator through pipeline, and said radiator is connected with water pump through pipeline; Said thermostat also directly is connected with water pump through pipeline.
Concrete characteristics of the present invention also have, and above-mentioned operator cabin warm braw water is parallelly connected with cylinder block cool cycles pipeline.
Said engine oil cooler cooling water channel is parallelly connected with cylinder block cool cycles pipeline.
Above-mentioned air compressor cooling water channel is parallelly connected with cylinder block cool cycles pipeline.
Above-mentioned cooler is a cooler for recycled exhaust gas.
Beneficial effect of the present invention is: easy for installation, simple in structure, connection interface is few, the fault point is few, guaranteed the reliability that motor uses.
Description of drawings
Fig. 1 is the theory structure schematic representation of the specific embodiment of the invention.
Embodiment
For clearly demonstrating the technical characterstic of this programme, through an embodiment, this programme is set forth below.
Shown in accompanying drawing; A kind of engine cooling circulation means comprises water pump, and said water pump is communicated with the import of cylinder head cooling circulation liquid, the import of cylinder block cooling circulation liquid respectively through pipeline; Said cylinder block cooling circulation liquid outlet converges the back with the outlet of cylinder head cooling circulation liquid through pipeline connection and is connected with cooler; Said cooler is connected with thermostat through pipeline, and said thermostat is connected with radiator through pipeline, and said radiator is connected with water pump through pipeline; Said thermostat also directly is connected with water pump through pipeline.Operator cabin warm braw water, oil cooler cooling water channel, air compressor cooling water channel are parallelly connected with cylinder block cool cycles pipeline.
After engine coolant came out from water pump, main circulation divided two-way to get into the cooling recirculation system of cylinder block and head respectively, and cooling liquid merges together after cylinder block and head is come out again, through cooler for recycled exhaust gas, got into thermostat or directly got back to water pump; This is according to the engine water temperature situation, if water temperature reaches setting temperature, then thermostat is opened, and cooling liquid gets into radiator, carries out major cycle, gets back to water pump then, continues circulation.If water temperature does not reach setting temperature, then thermostat is not opened, and cooling liquid is directly got back to water pump, carries out short circle.The most important inventive point of the present invention is, does not have the cool cycles interface between the cylinder block and head, and therefore, the fault point is few, has significantly reduced the risk that engine coolant is revealed.
The present invention can pass through or adopt existing techniques in realizing without the technical characteristics of describing; Repeat no more at this; Certainly, above-mentioned explanation is not to be limitation of the present invention, and the present invention also is not limited in above-mentioned giving an example; Variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present invention also should belong to protection scope of the present invention.
