Description
Technical field
The utility model relates to the automobile oil cooler, is used for in-engine machine oil is followed bad cooling.
Background technique
Being installed in the machine oil cooler between motor body and the filter cleaner, is a kind of be used for realizing oil and cooling liquid (example: the heat exchange water).Existing machine oil cooler, comprise water hull, cover plate and by the overlapping heat radiation fuse that forms of multilayer chiop, oil circuit and water route for being arranged alternately between the adjacent chips, be provided with fin in it, oil inlet hole on the described cover plate and oil outlet are communicated with the filler opening and the oil outlet of chip, and are communicated with oil circuit on the engine cylinder-body; Space in the water hull is communicated with the water route of chip chamber, and the energy road as cooling medium which is provided with fill hose joint and titting water outlet, is communicated with the cooling channel on the motor.Usually water hull is to separate to make with the heat radiation fuse, and then with bolt it is assembled together, and that is to say that cooler factory generally only provides the heat radiation fuse, and water hull and cover plate are made and responsible assembling by user oneself.Therefore, the volume and weight of complete machine is bigger, and structure is looser, and then cost is also higher relatively.In addition, because water hull is to separate design and make the also difficult control of its quality with the heat radiation fuse.
Owing to adopt fin to produce turbulent effect in oil circuit and the water route, thereby the heat exchanger of said structure also has following defective:
One, needs to adopt special-purpose fin part, thereby can increase cost, and reduce manufacturing efficiency.
Two, because fin is easy to produce burr, cause exchanger to contain granule foreign,, cause the motor premature wear along with the mobile of machine oil enters in the engine cylinder-body.
Three, there is the stagnant area in fin structure at oil duct import and export back, and it is very inhomogeneous to cause whole flow field to be distributed, thereby reduces heat exchange efficiency.
Summary of the invention
To be solved in the utility model is the problems referred to above that prior art exists, and aims to provide the heat exchanger that a kind of oil circuit flow field is even, heat exchange efficiency is higher and exchanger cleaning inside degree is higher.
The technological scheme that addresses the above problem employing is: the heat exchanger that does not have turbulent fin, comprise chip, it is characterized in that: multilayer chiop keeps at a certain distance away and is laminated, and its periphery superposes mutually and seal welding is linked to be an integral body, forms oil circuit and water route alternately between adjacent chips; Described every chip all has filler opening, oil outlet and the water intake that communicates with described water route, the water outlet that communicates with described oil circuit; Described chip is provided with a plurality of boss, and the boss on the adjacent chips staggers mutually.
Heat exchanger of the present utility model is with the disposable integral body that is welded as of oil circuit and water route, after being packaged together by the periphery with adjacent chips, directly form cooling water channel, no longer need to add the water hull body, make the integral product compact structure, volume is light and handy, has both alleviated weight, reduces manufacture cost again.What is more important, owing to adopt boss to replace fin structure, it also has the following advantages: one, the boss structure radiating effect is suitable with the fin structure radiating effect, thereby can reduce number of spare parts under the situation of identical performance, has improved productivity.Two, because fin structure useless has reduced the generation of burr, help the raising of turbidity test.Three, adopt the boss form structure, the flow field is more even, and the boss of streamwise and the stagnant area between boss are less.By quantity, space distribution situation, diameter and the stretching height of adjusting boss, can increase or reduce the aisle spare and the heat diffusion area in oil circuit and water route, and the running path that changes flowing medium, and then the pressure in change or control heat exchanging function and oil circuit and water route falls.
Further improve as of the present utility model, every chip is provided with center hole again, and described a plurality of boss are provided with in groups, every group of boss be distributed in one with the concentric circumference of this center hole on, make the flow field more even.
In order to ensure carrying out sufficient heat exchange between the medium in oil circuit and water route, increase the heat exchange area of machine oil in the oil circuit, widen the distance of oil inlet and outlet, so oil outlet is designed between water intake and water outlet as far as possible.Be positioned at filler opening front end place in the oil circuit side of described chip and be provided with the oily rib of retaining, be used for preventing that a large amount of oil from directly flowing through from the periphery of center hole, make the flow field more even.
For fear of make cooling water from straight-through between intake-outlet because of the distance between water intake and the water outlet is too short, the water route side of described chip also is provided with water bar or dash rib between water intake and water outlet, can increase the heat exchange area in water route.
Also be provided with stiffening plate and sealing front stall on the bottom chip successively, described stiffening plate and sealing front stall are provided with center hole corresponding with described chip and filler opening, and provide packing holder for the filter cleaner seat; Described top layer chip is provided with back seat, and described back seat is provided with intake pipe, outlet pipe, oil outlet and the mounting center hole that is communicated with water intake, water outlet, oil outlet, the mounting center hole of chip respectively, and provides sealing surface for oil filter.Oil outlet on the described back seat is near described center hole.During for the assurance cold start-up certain oily flow is arranged, by-pass hole of design on connecting plate.
