Description
Technical field
The present invention relates to a kind of hydraulic test, in particular to the hydraulic oil pipeline heat-exchanger rig of breakage-proof.
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 after cooler carries out heat exchange with the engine cooling water in 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, the machine flowed out in closed type hydraulic system is avoided
The instantaneous pressure of oil is excessive so as to cause to damage to radiator.
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, in shell
The same side of body is provided with the inlet connected respectively with heat exchanger tube both ends, liquid outlet, the housing opposite side be provided with
Cold liquid inlet, the cold liquid outlet of its internal connection, are provided with one end upper inside walls of the heat exchanger tube close to liquid outlet direction
Semicircular protuberance, and the changeover portion that section is arc-shaped is provided with the both ends of the protuberance, under corresponding to heat exchanger tube
Radially outstanding regulating tank is provided with the inwall of side, semicircular movable block, and activity are installed in regulating tank
The both ends of block are connected by organ type seal closure with heat transfer tube wall, on the end of the regulating tank of described liquid outlet one end
Spring is installed, and spring is connected with movable block side wall.
The present invention is in use, coolant enters enclosure interior by cold liquid inlet, 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, and the cooling that hydraulic oil is completed with this recycles.It will be tied in hydraulic oil cooling
Shu Shi, hydraulic oil quickly flow in heat exchanger tube, and swiftly flowing hydraulic oil can be to hydraulic oil delivery pipe when being flowed out by liquid outlet
Larger impact is caused, and then causes entirely to cool down and occurs local pressure concentration in circulation line and rupture, that is, is leaked
Oily phenomenon；In the present invention, before hydraulic oil flows out liquid outlet, semicircular protrusion is installed in the upper inside walls of heat exchanger tube
Portion, while regulating tank is being provided with 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 is formed and impacted, movable block then moves along a straight line in regulating tank, when movable block be moved to
During protuberance face, 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, for hydraulic oil then with a relatively slow flow velocity outflow liquid outlet, that is, realizing reduces liquid
The impact to cooling down circulation line is pressed oil, to prevent from cooling down the impaired rupture of 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, ensure 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 a guide function is played to hydraulic oil, that is, guide hydraulic oil by heat exchanger tube
Enter directly into protuberance, avoid hydraulic oil from forming vortex in heat exchanger tube and hinder it normally to circulate.
The heat exchanger tube is finned tube.Preferably, utilize 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, shorten 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, ensure hydraulic oil normal circulation without as formed block on the premise of, 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, makes hydraulic oil after abrupt deceleration
Gently flow into protuberance, while a guide function is played to hydraulic oil, that is, guide hydraulic oil to be directly entered by heat exchanger tube
Into protuberance, hydraulic oil is avoided to form vortex in heat exchanger tube and hinder it normally to circulate；
2nd, the present invention increases heat exchanger tube and shell from finned tube as heat exchanger tube using multiple fins of the protrusion on finned tube
The contact area of internal coolant, realizes the maximal efficiency of heat exchange between hydraulic oil and coolant, shortens the cooling of hydraulic oil
Time；
3rd, the internal diameter of the thickness ratio heat exchanger tube of protuberance is small in the present invention, is ensureing the normal circulation of hydraulic oil without as formation
On the premise of blocking, the thickness of protuberance is dimensioned to 1/3rd of heat exchange bore size so that the stream of hydraulic oil
Speed slows down without forming the impact to cooling down circulation line.
