Abstract
The utility model discloses a heat radiator for be used for hydraulic transmission system, including motor, screw pump, centrifugal fan, finned plate heat exchanger, screw pump one end and motor are connected through axle and axle sleeve cooperation, and the axle sleeve that the other end passed cab apron and centrifugal fan coordinates to be connected and drives the centrifugal fan rotation, it passes through the fastener with the wind scooper and is connected the vacuole formation to cross the cab apron, centrifugal fan arranges the cavity in, finned plate heat exchanger is fixed set up with cross the wind scooper outside that the cab apron is relative. In this way, the utility model discloses putting motor, screw pump, centrifugal fan, finned plate heat exchanger together, forming one and carry out radiating heat abstractor outside being independent of hydraulic transmission system, compact structure has effectively avoided compression shock and the flow pulse among the hydraulic system, reduces the loss to finned plate heat exchanger, also effective noise reduction, and structural design is reasonable, occupies smallly, and easy installation is dismantled.
Description
Technical field
This utility model relates to a kind of cooling device, is specifically related to a kind of heat abstractor for Hydraulic Power Transmission System.
Background technology
Hydraulic Power Transmission System, when acting, can make oil temperature rise because of energy loss, also can be high because of hydraulic system back pressure so that it is have a large amount of pressure loss in inoperative circulates, cause oil temperature to raise, and fluid heating can cause damage or the degradation of multiple hydraulic component；After entering air in loop, hydraulic system will circulate at higher-pressure region low-pressure area along with fluid, is constantly mixed into, dissolve in fluid or separate out from fluid middle reaches, produce compression shock and makes oil temperature steeply rise, cause fluid oxidation deterioration and part to degrade；So hydraulic transmission element and heat exchanger set would generally be integrated; cooling oil temperature is carried out for heat radiation; but there is compression shock in various degree and flow pulse in fluid system; the life and reliability of heat abstractor is caused strong influence by heat exchanging process, and whole equipment exists relatively larger noise in operation process.
Utility model content
Technical problem to be solved in the utility model is to provide the heat abstractor of a kind of compact conformation for the above-mentioned state of the art, can be prevented effectively from the compression shock in hydraulic system and flow pulse, thus reducing noise, and reasonable in design, easy installing/dismounting.
The technical scheme that the above-mentioned technical problem of this utility model solution adopts is: a kind of heat abstractor for Hydraulic Power Transmission System, it is characterized in that: include motor, screw pump, centrifugal fan, plate-fin heat exchanger, described screw pump one end is connected by axle and axle sleeve with motor, the axle sleeve of other end traverse rebound and centrifugal fan is connected and drives centrifugal fan to rotate, described rebound is connected formation cavity with wind scooper by securing member, described centrifugal fan is placed in cavity, described plate-fin heat exchanger is fixedly installed on outside the wind scooper relative with described rebound.
As improvement, described plate-fin heat exchanger upper end is provided with oil-out, and lower end is provided with oil-in.
Improve again, described screw pump is provided with oil-in and oil-out, the described oil-out oil-in by hose connection plate-fin heat exchanger.
Improving further, described fan housing exterior bottom is provided with a support, is fixedly connected on described plate-fin heat exchanger.
Finally, centrifugal fan is air draught type, and air draft direction is perpendicular to import wind direction.
The beneficial effects of the utility model are: this utility model is designed by shaft type, motor, screw pump, centrifugal fan, plate-fin heat exchanger are combined, form one independent of the heat abstractor carrying out outside Hydraulic Power Transmission System dispelling the heat, compact conformation, effectively prevent the compression shock in hydraulic system and flow pulse, reduces the loss to plate-fin heat exchanger, also noise is effectively reduced, reasonable in design, takies volume little, easy installing/dismounting.
Accompanying drawing explanation
Fig. 1 is the perspective view of this utility model heat abstractor.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model being made apparent clear and definite defining.
As shown in Figure 1, a kind of heat abstractor for Hydraulic Power Transmission System, including motor 1, screw pump 2, centrifugal fan 3, plate-fin heat exchanger 4, wherein screw pump 2 one end is connected by axle and axle sleeve with motor 1, the axle sleeve of other end traverse rebound 6 and centrifugal fan 3 is connected and drives centrifugal fan 3 to rotate, by motor 1, screw pump 2, centrifugal fan 3 is designed by shaft type, connect compact, reduce and take up room, rebound 3 is connected formation cavity with wind scooper 5 by securing member simultaneously, centrifugal fan 3 is placed in cavity, and plate-fin heat exchanger 4 is fixedly installed on outside the wind scooper 5 relative with rebound 6, it is fixed on wind scooper 5 exterior bottom with support 7 simultaneously, play the effect of gripper shoe fin heat exchanger 4, plate-fin heat exchanger 4 upper end is provided with oil-out 4a, lower end is provided with oil-in 4b, same screw pump 2 is also equipped with oil-in 2a and oil-out 2b, the oil-out 2b of screw pump 2 is connected with the oil-in 4a of plate-fin heat exchanger 4 by flexible pipe.
During work, motor 1 first drives screw pump 2 by flexible pipe from oil suction fuel tank, the internal channel of plate-fin heat exchanger 4 squeezed into by the oil that screw pump 2 is inhaled again through another flexible pipe, motor 1 drives screw pump 2 to drive centrifugal fan 3 to operate simultaneously, from air, air draught enters the outer tunnel of plate-fin heat exchanger 4, and enter the hydraulic oil that wind scooper 5 is internally formed in air stream and plate-fin heat exchanger 4 internal channel and carry out heat exchange, the heat taken away by air is gone out by centrifugal fan 3 air draft above wind scooper 5.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description and accompanying drawing content to make or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, all in like manner include in scope of patent protection of the present utility model.
