Description
Technical Field
The utility model relates to an engineering truck radiator technical field especially relates to an improve structure of water-cooled oil cooler radiating efficiency.
Background
The hydraulic system of the existing non-road engineering mechanical vehicle is generally applied to non-road engineering mechanical equipment, a diesel engine is used as a power source machine, a driving hydraulic pump conveys oil liquid to a power execution structure at high pressure, the oil liquid is generated at high pressure and is accompanied with heat power loss when mechanical energy is converted, if the efficiency of the oil liquid circulation whole hydraulic system in a high-temperature state can be greatly reduced, simultaneously, the aging of a hydraulic oil pipe is accelerated, the service life is prolonged, meanwhile, the gear clearance is enlarged due to the overhigh temperature in a pump valve, the efficiency of the pump valve is low, more importantly, the damage to core hydraulic parts is caused, and the maintenance cost is high.
The existing loader has large work and larger oil flow of a hydraulic system, so that the whole hydraulic system is definitely required to be cooled in power cooling so as to ensure the good state of each part in the hydraulic system. Because of the characteristic of high oil return peak pulse of a hydraulic system, the existing hydraulic oil heat dissipation module mostly adopts a pipe belt type oil radiator, an aluminum plate fin type oil radiator and a stainless steel water cooling type oil cooler which are formed by brazing extruded aluminum oil pipes. The hot side channel of the water-cooling fin type oil cooler is of a sandwich plate type structure, stainless steel fins are designed between plates and are stacked and brazed, and the water-cooling fin type oil cooler is used by a whole machine due to the characteristics of strong bearing capacity, high product reliability, small size, high heat exchange efficiency, good corrosivity and flexible product matching arrangement.
The plate type oil cooler used in the existing market is arranged, low-temperature water is used for cooling the outside of the oil cooler after the cooling liquid with large mass flow of an engine is used for cooling the outside of the oil cooler, high-temperature oil in a plate bundle of the plate type oil cooler is subjected to heat exchange, a good heat dissipation effect is obtained due to large liquid-liquid temperature difference of a cold side and a hot side, and good design cost is obtained under the condition of ensuring use.
Traditional water-cooled plate cooler is as "soaking" formula design in cooling system, is about to install plate oil cooler in a sealed hydroecium casing, and the plate bundle both ends of plate oil cooler hot side are fluid import and export respectively, and high temperature oil gets into from the import, and the low temperature oil after the cooling goes out from the export, and the contact of the low temperature cooling water after the surface of plate bundle simultaneously and cooling carries out radiating heat exchange through the convection current of cold hot side to reach the radiating purpose of fluid. But most designs fail to carry out reasonable design, often lack the waste that has caused the product design, can't obtain good product design utility, cause the cryogenic cooling liquid to fail to carry out effectual surface heat exchange to water-cooled chip oil cooler, lead to the bad problem of fluid heat dissipation.
Disclosure of Invention
To the not enough among the above-mentioned prior art, the utility model provides an improve water-cooled oil cooler radiating efficiency's structure can improve current water-cooled piece formula oil cooler radiating efficiency.
In order to achieve the above object, the present invention provides a structure for improving the heat dissipation efficiency of a water-cooled oil cooler, which comprises an oil cooler cover plate, a side guide plate and an end guide plate; the oil cooler cover plate forms a water inlet and is connected to the top of an oil cooler; the side guide plate is fixed on one side of the bottom surface of the oil cooler cover plate along the length direction of the oil cooler cover plate; the end guide plate is vertically fixed at one end of the side guide plate, which is close to the water outlet of the oil cooler.
Preferably, the cross section of the side guide plate is C-shaped, and the opening part is arranged towards the water inlet.
Preferably, the end deflector is formed with a plurality of concave-convex positioning notches.
The utility model discloses owing to adopted above technical scheme, make it have following beneficial effect:
through the adoption of the side guide plate and the end guide plate, the cooling liquid at the water inlet of the oil cooler assembly is dredged, a flow channel of the dredged cooling liquid uniformly passes through the oil cooler plate bundle interlayer, and meanwhile, the backflow of high-temperature water after the cold side is washed away is avoided, so that the cooling efficiency is improved. Through carrying out wind tunnel test to the structure product after increasing the water conservancy diversion and improving, under the same test condition, improve the product radiating efficiency and promote 38% before improving after improving, have higher product design utility to promote. The concave-convex positioning notch is convenient to assemble, weld and quickly position, and the problems of product design utility discount or finished product assembly interference caused by production errors are thoroughly avoided starting from a design source.
