Description

Diesel engine filtering cooling unit

Technical field

The utility model relates to a kind of diesel engine cooling unit, particularly a kind of diesel engine filtering cooling unit.

Background technique

The diesel engine sink is most important for the engine mechanical transmission, diesel engine in the course of the work, because fuel oil burns in cylinder sleeve, produce a large amount of heats, heat is propagated to all directions of body by medium, if adopt natural heat dissipation, the thermal equilibrium temperature of natural heat dissipation is raise, make the temperature of machine oil too high, and the oil temperature is when surpassing allowable temperature, its lubrication system will be destroyed, thereby will cause the motor parts to be subjected to fire damage, and make shorten the machine time in working life, like this, the ability of entire machine equipment just can not get due performance, causes economic loss to production.At present, what the cooling system of a lot of diesel engine used is the separated type design, just oil filter, oil filter seat and " device of shifting block type " or " tube still type " oil cooler is installed in respectively outside the body, is connected in order to make machine oil, have only and use oil pipe that they are coupled together respectively, just can reach the logical oily effect of machine oil, such meeting causes uses too much oil pipe, and the oil pipe long term exposure outside, aging easily, and cooling effect is undesirable, and it is big to take up room, and installs also cumbersome.

Summary of the invention

In order to remedy above deficiency, the utility model provides a kind of diesel engine filtering cooling unit, and this diesel engine filtering cooling unit is simple in structure, and fully lubricated, cooling effect is remarkable.

The utility model for the technological scheme that solves its technical problem and adopt is: a kind of diesel engine filtering cooling unit, comprise filter cleaner, filter cleaner seat and oil cooler, filter cleaner, filter cleaner seat and oil cooler are fixedly arranged on the body outside respectively, be provided with first in the filter cleaner seat, two filler openings, first, two oil outlets and first, two, three oil passageways, first filler opening outside in the filter cleaner seat is communicated with oil-servicing facilities, first filler opening is inboard to be communicated with the cooling import of oil cooler by first oil passageway, the coolant outlet of oil cooler is communicated with the 3rd oil passageway of filter cleaner seat, the 3rd oil passageway of filter cleaner seat is communicated with first oil outlet of filter cleaner seat, machine oil fully cools off by oil cooler, first oil outlet outside of filter cleaner seat is communicated with the filtering filler opening of filter cleaner, the filtering oil outlet of filter cleaner is communicated with second filler opening of filter cleaner seat, after entering the filter cleaner filtering, the machine oil of cooling comes back in the filter cleaner seat, second filler opening of filter cleaner seat is communicated with second oil outlet by second oil passageway, second oil outlet of filter cleaner seat is communicated with internal body, be discharged in the motor through the machine oil of supercooling and filtering motor is lubricated, to use direction to be benchmark, filter cleaner is positioned at filter cleaner seat below, the filtering of filter cleaner is advanced, oil outlet is communicated with by hollow swivel nut with first oil outlet and second filler opening of filter cleaner seat respectively, in the seal space that oil cooler forms between filter cleaner seat and body, oil cooler cools off into, outlet is respectively by fastening piece (can be thread seal and connect multiple Placements such as also can be interference sealing engagement connection) first of direct and filter cleaner seat, three oil passageways are communicated with, make whole filtering cooling unit simple in structure like this, compact, it is also convenient to install simultaneously, also saved oil pipe, it is aging easily also just to have solved oil pipe, defectives such as it is big to take up room have been saved the space, prolonged motor working life.

As further improvement of the utility model, also be provided with water intake, water channel and water outlet in the filter cleaner seat, water intake is communicated with water outlet by water channel, wherein water channel is around the outer periphery place that is positioned at oil cooler and first and third oil passageway, the water channel cold water that allows capable of circulation in the filter cleaner seat passes through, allow cold water that the heat in oil cooler and the filter cleaner seat is taken away, machine oil is further cooled off.

As further improvement of the utility model, oil cooler is the plate and fin type oil cooler, and the disturbance of the fin convection cell of plate and fin type oil cooler is constantly broken the boundary layer, thereby has the bigger coefficient of heat transfer; While is owing to dividing plate, fin are very thin; has high thermal conductivity; so that plate-fin heat exchanger can reach very high heat transfer efficiency; make between high temperature grease and the cooling water and realize heat exchange; can significantly reduce the oil temperature; thereby the thermal power that improves motor makes it reach specified mechanical output; to give full play to the load carrying capacity of machinery; and protect the parts of motor not to be subjected to fire damage, prolong to use and receive a mandate its compact structure; two subsurfaces with expansion; make its specific surface area height, adaptability is strong, and it is little to take up room.

As further improvement of the utility model, plate and fin type oil cooler material is a stainless steel, can increase the intensity of oil cooler and antirust like this, effectively increases oil cooler working life.

As further improvement of the utility model; the opposite that the filter cleaner seat is positioned at first filler opening is provided with a bypass valve; when the overpressure of filter cleaner seat first filler opening; bypass valve is opened; machine oil reduces through the bypass downstream pressure, can first, second and third oil passageway and other component of filter cleaner seat be played a protective role like this.

Useful technique effect of the present utility model is: filter cleaner of the present utility model directly is communicated with by hollow swivel nut with the filter cleaner seat, the while oil cooler is placed on the filter cleaner seat and also directly is communicated with the filter cleaner seat by fastening piece with the enclosed space of body formation is interior, whole like this filtering cooling unit is simple in structure, compact, simultaneously easy for installation, also saved oil pipe, solved the oil pipe defective such as big that wears out easily, takes up room, saved the space, prolonged motor working life.
