Abstract
The invention discloses an oil cooler of air cooled engine. The oil cooler is a condenser arranged at the air inlet part of an engine air guide cover; an oil inlet tube and an oil outlet tube of the condenser are arranged in a U shape; and a thermal insulation layer is arranged between the oil inlet tube and the oil outlet tube of the condenser. According to the invention, a thermal insulation layer obstructs the direct thermal conduction between the oil inlet tube and the oil outlet tube, and the heat transfer efficiency is improved. through the invention, the problem that the direct thermal conduction between the oil inlet tube and the oil outlet tube reduces the heat exchange efficiency is solved; the oil temperature at the outlet is guaranteed; and the cooling effect is good as the thermal conduction between the oil inlet tube and the oil outlet tube is reduced, the space of the shell is reasonably utilized, and the tangential air of a fan flywheel is fully used.
Description
Technical field
The present invention relates to the external machine oil condenser of a kind of air cooling engine intake grill.
Background technique
Air cooling engine adopts natural air inlet; Cooling by force; Mainly using the fan blade that is contained on the flywheel when engine running, to produce blast cools off engine; Usually air cooling engine oil temperature (thermic load) only utilizes the heat transfer of fin and the body of engine itself to carry out heat exchange to come the controller oil temperature; Yet when power ruggedization; The thermic load of engine can be very high; Cause the oil temperature of engine sharply to rise; And when oil temperature rises to more than 120 ℃; The lubricated kinematic viscosity of machine oil sharply descends; Require heat radiation in time, could guarantee the continuous service of engine good state and permanent service life.
Before the present invention makes, in prior art, after the lubricant oil cooling; Keep cooling back this problem of temperature often out in the cold, generally adopt condenser turnover oil pipe double, and directly contact; Cause the heat transfer problem of short-circuit, directly influenced the oil outlet temperature, reduced heat exchange efficiency significantly.The above-mentioned lubricant oil type of cooling is difficult to accomplish favorable cooling effect, and the bad cooling effect of lubricant oil tends to cause that engine temperature rises then, and output power descends, and very easily produces faults such as Bearing score, scuffing of cylinder bore, the unwarrantable problem of engine reliability.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructure, the air cooling engine machine oil cooler that heat exchange efficiency is high.
Technical solution of the present invention is:
A kind of air cooling engine machine oil cooler, for being arranged on the condenser at motor wind scooper intake grill position, it is characterized in that: the oil inlet pipe of condenser and oil outlet tube are arranged in the U type, between the oil inlet pipe of condenser and oil outlet tube, thermal-protective coating are set.
Said thermal-protective coating comprises tabular body, and the two sides is provided with projection on the tabular body.
Said projection is arranged on the intermediate portion and/or the two-end part of tabular body.
Thermal-protective coating adopts the thermal conductivity materials with smaller.
Said hot coefficient materials with smaller is silica gel or rubber.
The present invention adopts thermal-protective coating, has intercepted direct heat conduction between the turnover oil pipe, has improved heat exchange efficiency.The invention solves the problem of the direct heat conduction reduction heat exchange efficiency between the turnover oil pipe; Guarantee the outlet port oil temperature, utilized the transmission of heat that reduces between the turnover oil pipe, rationally utilized the space of housing; Make full use of the tangential wind of fan flywheel, thereby good cooling results.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is the partial view of Fig. 1.
Fig. 3, Fig. 4, Fig. 5, Fig. 6 are the schematic representation that the present invention adopts different heat insulation layer forms.
Embodiment
A kind of air cooling engine machine oil cooler, for being arranged on the condenser 1 at motor wind scooper intake grill position, the oil inlet pipe of condenser and oil outlet tube are arranged in the U type, between the oil inlet pipe of condenser and oil outlet tube, thermal-protective coating 2 are set.Heat insulation layer adopts the thermal conductivity materials with smaller, like silica gel or rubber etc.Said thermal-protective coating comprises tabular body, and the two sides is provided with projection 3 on the tabular body.
Said projection is arranged on the intermediate portion and/or the two-end part of tabular body.As shown in Figure 3; In the middle of thermal-protective coating, place one or more projection; The fluid that can increase the condenser two ends flows, and as shown in Figure 4, respectively places a projection at the thermal-protective coating two ends; Can increase the air ventilation of intermediate section; As shown in Figure 5, longer for the length of condenser, all place projection at thermal-protective coating two ends and centre; Make the condenser heat exchange of each section all significantly increase, thereby can guarantee the outlet port oil temperature.Fig. 6 is the situation of the not relative thermal baffle symmetry of projection.
