Abstract
The invention relates to an engine oil cooler, which belongs to the technical field of engine oil coolers. The cooler mainly comprises a cooler shell, a plate-fin cooler core, a cooler cover, a cooler cover gasket and an anti-freezing drainage switch, wherein the plate-fin cooler core is positioned in a cavity formed by the cooler shell, the cooler cover gasket and the cooler cover and fixed on the cooler shell through screws; and both sides of the bottom surface of the cooler shell are provided with an oil inlet and an oil outlet respectively. The cooler is characterized in that: a guide plate is fixed in a concave pit on the inner surface of the cooler cover through screws; a plurality of flow diversion rib plates are arranged in the cooler shell; one side of the cooler cover is provided with a water inlet; and one side of the cooler shell is provided with a water outlet. The engine oil cooler can make convective heat exchange between engine oil and cooling water in the cooler core very sufficient, so that heat exchanging efficiency is greatly improved. Therefore, the engine oil cooler has better cooling effect.
Description
Technical field
The present invention relates to a kind of machine oil cooler, belong to the machine oil cooler technical field.
Background technique
At present, motor adopts machine oil cooler more and more general, no matter be coil insertion device oil cooler, semi-independent formula machine oil cooler, or free-standing machine oil cooler, the working principle basically identical: water-cooling engine oil cooler carries out convection heat exchange by the circulation and the circulation of high temperature oil in the cooler core oil pocket of cooling liquid in the cooler water cavity, with the lower cooling liquid of temperature to the cooling that circulates of the higher machine oil of temperature, guaranteeing that oil temperature is controlled in the comparatively ideal scope, thereby guarantee the service behaviour and the emission request of motor.In existing machine oil cooler, cooler core great majority employing plate and fin type, this cooler core cooling effectiveness is than higher, and performance is reliable, and manufacturing technology is also very ripe.Cooler casing generally has casting and welds two kinds of patterns, but the design of the cooler casing of which kind of pattern all is tending towards fairly simple, the inner flow guide structure of reasonably not arranging the current trend of shell itself.Therefore make the chiller efficiency of cooler be difficult to further improve.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, thereby a kind of machine oil cooler is provided, this structure machine oil cooler can make machine oil and cooling water convection heat exchange in the cooler core carry out very fully, thereby guarantee that cooler has better cooling; In using process in the future, have the snaking of being easy to, be convenient to advantages such as maintenance.
According to technological scheme provided by the invention, a kind of machine oil cooler comprises cooler casing, strip-fin oil cooler core, cooler head, cooler head pad and antifreeze cock of water drain, use the cooler head gasket seal between described cooler casing and the cooler head, the strip-fin oil cooler core is positioned at the chamber that is formed by cooler casing, cooler head pad and cooler head, and is fixed on the cooler casing by screw; Described cooler casing is provided with antifreeze cock of water drain, both sides, cooler casing bottom surface are respectively equipped with filler opening and oil outlet, and filler opening and oil outlet are being communicated with filler opening and oil outlet on the cooler core respectively, feature is: the internal surface pit of described cooler head has guide plate by screw, is provided with many water conservancy diversion gussets in the described cooler casing.
Described cooler head one side is provided with water intake.One side of described cooler casing is provided with water outlet.
Be provided with fluororubber O shape circle in the O shape groove between the turnover oil process orchid of described cooler casing and strip-fin oil cooler core, be used to seal machine oil.
The invention has the advantages that: since in the cooler casing internal placement guide plate of installing on many water conservancy diversion gussets and the cooler head, and intake-outlet and oil inlet and outlet relative position arrange more reasonable, the heat exchange efficiency of this machine oil cooler is compared with other uniform machines oil coolers is greatly improved; After low temperature water enters the cooler water cavity, current according to the current route reciprocating and turning-back of guide plate and water conservancy diversion gusset constraint pass cooler core several times after, flow out from water outlet again, so just make machine oil and cooling water convection heat exchange in the cooler core carry out very fully, thereby guaranteed that cooler has better cooling effect.Cooler casing, cooler core and cooler head are relatively independent several parts, have the snaking of being easy in using process in the future, are convenient to advantages such as maintenance.

Embodiment
Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
As Fig. 1～shown in Figure 5, comprise cooler casing 1, fluororubber O shape circle 2, strip-fin oil cooler core 3, cooler head pad 4, cooler head 5, guide plate 6 and antifreeze cock of water drain 9.
Bian is positioned at the chamber that is formed by cooler casing 1, cooler head pad 4 and cooler head 5 with strip-fin oil cooler core 3 among the present invention, and is fixed on the cooler casing 1 by screw 8.In the O shape groove of fluororubber O shape circle 2 between the turnover oil process orchid of cooler casing 1 and cooler core 3, be used to seal machine oil.Cooler head pad 4 is used to seal the cooling water in its chamber between cooler casing 1 and cooler head 5, guide plate 6 is fixed on the internal surface pit of cooler head by screw 7, described cooler head 5 one sides are provided with water intake 10, one side of described cooler casing 1 is provided with water outlet 11, opposite side is provided with antifreeze cock of water drain 9, both sides, cooler casing 1 bottom surface are respectively equipped with filler opening 12 and oil outlet 13, and filler opening 12 and oil outlet 13 are communicated with filler opening and oil outlet on the plate and fin type cooler core respectively.
Owing in cooler casing 1, arranged many water conservancy diversion gussets 14 and mounting guiding board 6 on cooler head 5, and after the current reciprocating and turning-back passes cooler core 3 several times under the constraint of water conservancy diversion gusset 14, flow out from water outlet 11 again, the convection heat exchange by strip-fin oil cooler core 3 carries out very fully between cooling water and the machine oil with regard to impelling like this, and intake-outlet and oil inlet and outlet relative position are arranged also relatively rationally, also help to improve the convection heat exchange of cooler inside, therefore this machine oil cooler heat exchange efficiency has obtained improving greatly, thereby guarantees that this machine oil cooler has better cooling effect.
When engine operation, after the lower water of temperature that pump outlet flows out flow to a side water intake 10 of cooler head 5, cooling water enters by cooler casing 1 under the constraint of guide plate 6, cooler core 3, in the water cavity that cooler head pad 4 and cooler head 5 form, the cooling water reciprocating and turning-back under the constraint of cooler casing 1 inner water conservancy diversion gusset 14 that has pressure at last passes plate fin oil cooler core 3 several times, the higher machine oil of temperature enters strip-fin oil cooler core 3 inside from filler opening 12, after the two carries out exchange heat by strip-fin oil cooler core 3, current flow out from water outlet 11, the heat of machine oil is taken away, cooled machine oil is logical to flow out from oil outlet 13, flow back to the body main oil gallery by the oil duct on the oil filter seat, thereby guarantee engine reliable running stably, and guarantee that the running of motor is in good state.
