Abstract
The invention provides a protective structure for a waterproof ventilated membrane. The protective structure for a waterproof ventilated membrane comprises a waterproof ventilated membrane, a screw fixing hole, a screw fixing hole, a rear cover, a ventilated membrane protective cap, a screw mounting hole, a screw mounting hole, an internal layer ventilating space, an internal layer upper ventilating groove, an internal layer lower ventilating groove, an external layer ventilating space, an external layer lower draining ventilating groove, and an external layer upper ventilating groove and screws. The protective structure for a waterproof ventilated membrane can solve the problems that the internal pressure is improved because the internal temperature in the controller is improved, and the generated pressure is accumulated in the housing so that a pressure release channel is required, and the channel may be blocked by sludge and impurities.
Description
Technical field
The invention belongs to automobile engine cooling technology field, particularly relate to a kind of safeguard structure of the waterproof ventilated membrane for automobile engine cooling fan electronic controller.
Background technology
Very large heat can be produced during the work of automobile engine cooling fan electronic controller high performance components, controller internal temperature is raised, causes air pressure inside to uprise, the pressure of generation overstocks at housing, need pressure release passage, therefore usually adopt the hermetically-sealed construction installing waterproof ventilated membrane.Because long-term work is when environmental condition is quite severe, there is the risk blocked by impurity in waterproof ventilated membrane, after hole plug, inner air just cannot be discharged, and causes air pressure inside too high, can destruct limit device sealing property.
Summary of the invention
The safeguard structure that the invention provides a kind of waterproof ventilated membrane solves the above problem blocked by mud impurity occurred.A safeguard structure for waterproof ventilated membrane, is made up of ventilating groove, screw on ventilating groove, outer ventilation space, outer lower draining ventilating groove, skin under ventilating groove, internal layer on waterproof ventilated membrane, screw fixed hole, screw fixed hole, bonnet, ventilated membrane over cap, screw mounting hole, screw mounting hole, internal layer ventilation space, internal layer.Described safeguard structure is installed on above air-vent, to play the effect of protection; Described waterproof and breathable structure comprises installs the bonnet of ventilated membrane, the housing of safeguard structure to be provided with the waterproof and breathable space of internal layer described in the screw be connected and fixed between bonnet and housing, this space is provided with two ventilating grooves, and thermal current enters internal layer ventilation space by these two ports; Describedly be provided with draining air-vent bottom at safeguard structure outer casing, top is provided with steam vent.Be covered with ventilated membrane installing hole and screw mounting hole after described, ventilated membrane installing hole is used for ventilated membrane and installs; Screw mounting hole is used for protective cover screw to be fixed; Described protective cover to be provided with on internal layer ventilation space, internal layer ventilating groove under ventilating groove, internal layer, outer ventilation space, outer ventilative and steam vent, outer upper air-vent; Described screw is used for fixed protection lid.
Structure of the present invention is simple, design science, reasonable, novel, and simple structure, reliable effect, cost is low, effectively solves the problem that waterproof ventilated membrane gets clogged.
Below in conjunction with drawings and Examples, the present invention is further described, object of the present invention, advantage and disadvantage, made an explanation by the non-limitative illustration of preferred embodiments below.
Accompanying drawing explanation
Fig. 1 is structural upright explosive view of the present invention;
Fig. 2 is safeguard structure housing cross-sectional schematic of the present invention;
In above accompanying drawing: 10-waterproof ventilated membrane; 11-screw fixed hole; 12-screw fixed hole; 13-bonnet; 20-ventilated membrane over cap; 21-screw mounting hole; 22-screw mounting hole; 23-internal layer ventilation space; Ventilating groove on 24-internal layer; Ventilating groove under 25-internal layer; The outer ventilation space of 26-; Draining ventilating groove under 27-skin; Ventilating groove on 28-skin; 30-screw.
Below in conjunction with drawings and Examples, the present invention is further illustrated.
Embodiment
Built-in automobile air-conditioning controller knob construction of switch of the present invention, is shown in shown in Fig. 1, Fig. 2.
Embodiment one: practical safeguard function; ventilated membrane over cap (20) screw (30) is fixed on bonnet (13); when outside sewage is splashed into; can only directly splash on ventilated membrane over cap (20); directly protection is defined to ventilated membrane; because of size and the position restriction of each ventilating groove (24) (25) (27) (28); impurity directly cannot be entered on inner ventilated membrane, add the useful life of ventilated membrane.
Embodiment two: degassing function, interiors of products air pressure is discharged to internal layer ventilation space (23) through waterproof ventilated membrane ventilated membrane (10), on internal layer, gas is discharged to outer ventilation space (26) with ventilating groove (25) under internal layer by ventilating groove (24), under skin, draining ventilating groove (27) is vented with ventilating groove (28) on skin again, forms a ventilative passage.
In addition to the above, the present invention can also have other execution modes, does not speak approvingly of one by one at this.In every case the technical scheme adopting equivalent replacement or equivalent transformation to be formed, all belongs to the protection range of application claims.
