Description
Technical field
The present invention relates to a kind of hydraulic test, the hydraulic oil pipeline heat-exchanger rig of breakage-proof is specifically referred to.
Background technology
Oil cooler is provided with fluid drive vehicle, for entering to the engine motor oil in torque-converters or power drive system
Row cooling, high temperature oil enters carries out heat exchange with the engine cooling water in cooler after cooler, and then machine oil is carried out
Cooling., can be excessive so as to dissipating due to the instantaneous pressure of the machine oil flowed out in closed type hydraulic system when traditional radiator works
Hot device causes to damage, and influences the normal work of radiator.
The content of the invention
It is an object of the invention to provide the hydraulic oil pipeline heat-exchanger rig of breakage-proof, it is to avoid is flowed out in closed type hydraulic system
Machine oil instantaneous pressure it is excessive so as to radiator cause damage.
The purpose of the present invention is achieved through the following technical solutions：
The hydraulic oil pipeline heat-exchanger rig of breakage-proof, including housing and bending fold are placed on the heat exchanger tube in housing,
The same side of housing is provided with the inlet connected respectively with heat exchanger tube two ends, liquid outlet, set in the opposite side of the housing
Have and exported with its internal cold liquid import connected, cold liquid, in the heat exchanger tube in one end upper inside walls in liquid outlet direction
Provided with semicircular protuberance, and at the two ends of the protuberance provided with the changeover portion that section is arc-shaped, in heat exchanger tube correspondence
Downside inwall on be provided with radially outstanding regulating tank, semicircular movable block is installed in regulating tank, and
The two ends of movable block are connected by organ type seal closure with heat exchange inside pipe wall, at the end of the regulating tank close to described liquid outlet one end

The present invention enters enclosure interior in use, coolant leads to supercooled liquid import, the liquid when filling coolant in housing
Force feed is flowed into heat exchanger tube by inlet, passes through the heat exchange process of coolant in heat exchanger tube and housing so that the temperature of hydraulic oil
Degree is quickly reduced, and is then discharged by liquid outlet, is recycled with the cooling that this completes hydraulic oil.It will be tied in hydraulic oil cooling
Shu Shi, hydraulic oil quickly flows in heat exchanger tube, and swiftly flowing hydraulic oil can be to hydraulic oil delivery pipe when being flowed out by liquid outlet
Cause larger impact, so cause entirely to cool down occur in circulation line local pressure concentrate and rupture, that is, leak
Oily phenomenon；In the present invention, before hydraulic oil outflow liquid outlet, semicircular protrusion is installed in the upper inside walls of heat exchanger tube
Portion, while being provided with regulating tank on the downside of heat exchanger tube on inwall, movable block is slidably arranged in regulating tank, and regulating tank passes through organ
Formula seal closure is kept apart with heat exchanger tube, and the upper end of movable block protrudes from the upper surface of organ type seal closure so that in hydraulic oil
During flow at high speed, directly movable block formation is impacted, movable block then moves along a straight line in regulating tank, when movable block be moved to
Protuberance just pair when, now spring is compressed, and the runner internal diameter size of hydraulic oil diminishes suddenly, movable block and protuberance phase interworking
Close, to realize the reduced velocity flow of hydraulic oil, hydraulic oil then with a relatively slow flow velocity outflow liquid outlet, that is, realizes reduction liquid
The impact to cooling down circulation line is pressed oil, to prevent the impaired rupture of cooling circulation line；And when the flow and flow velocity phase of hydraulic oil
To it is smaller when, spring-return deformation causes movable block to be staggered with protuberance so that the runner of hydraulic oil increases again, it is ensured that liquid
The normal circulation of force feed.Also, the changeover portion that a section is arc-shaped is provided at both ends with protuberance, makes hydraulic oil rapid
Gently flowed into after so slowing down in protuberance, while playing a guide function to hydraulic oil, that is, guide hydraulic oil by heat exchanger tube
Enter directly into protuberance, it is to avoid hydraulic oil hinders it normally to circulate in heat exchanger tube formation vortex.
The heat exchanger tube is finned tube.Preferably, utilizing the protrusion on finned tube as heat exchanger tube from finned tube
Multiple fins increase the contact area of coolant in heat exchanger tube and housing, realize that heat exchange is most between hydraulic oil and coolant
Big efficiency, shortens the cool time of hydraulic oil.
The thickness of the protuberance is 1/3rd of the heat exchange bore.The internal diameter of the thickness ratio heat exchanger tube of protuberance
It is small, on the premise of the normal circulation of guarantee hydraulic oil is without as blocking is formed, the thickness of protuberance is dimensioned to change
/ 3rd of heat pipe internal diameter size so that the reduced velocity flow of hydraulic oil is without forming the impact to cooling down circulation line.
The present invention compared with prior art, has the following advantages and advantages：
1st, the present invention is provided at both ends with the changeover portion that a section is arc-shaped in protuberance, hydraulic oil is being subtracted suddenly
Gently flowed into after speed in protuberance, while playing a guide function to hydraulic oil, that is, guide hydraulic oil direct by heat exchanger tube
Enter in protuberance, it is to avoid hydraulic oil hinders it normally to circulate in heat exchanger tube formation vortex；
2nd, the present invention increases heat exchanger tube from finned tube as heat exchanger tube using multiple fins of the protrusion on finned tube
With the contact area of coolant in housing, the maximal efficiency of heat exchange between hydraulic oil and coolant is realized, shortens hydraulic oil
Cool time；
3rd, the present invention in protuberance thickness ratio heat exchanger tube internal diameter it is small, ensure hydraulic oil normal circulation without as
Formed on the premise of blocking, the thickness of protuberance is dimensioned to 1/3rd of heat exchange bore size so that hydraulic oil
Reduced velocity flow without formed to cool down circulation line impact.
