Description

Plastic member
Technical field
The present invention relates to a kind of plastic member, particularly a kind of heat exchanger of particularly power actuated vehicle or the plastic member of conditioning unit.
Background technology
Plastic member especially for heat exchanger or conditioning unit has at least one wall portion, and this wall portion is generally designed to relatively thin and has for reinforcing reason the reinforcing rib being arranged on outside or inside.Therefore, it is known for having the heat exchanger manifold being arranged on outside reinforcing rib.Such conditioning unit housing is also known, and these housings have reinforcing rib in outside, to improve the rigidity of quite large-area element.
Relative to the design of component wall portion, the design of reinforcing rib needs the additional materials that must be used for improving rigidity, but this can raise the cost.
The housing that DE102008002408A1 has also disclosed conditioning unit can construct with different materials, and wherein, bearing area is made up of the good material of rigidity and by this point, non-bearing region requires that not too high material is formed.
DE10335434A1 discloses a kind of vent passages for interior chamber ventilated, and in this vent passages, wall portion is consisted of according to hexagonal lattice structure triangular element, these triangular elements difference relative tilt a little, thus produces protruding and adjacent recesses.But this component with the surface of respective design does not particularly demonstrate required rigidity when the maximum internal pressure occurred.
Summary of the invention
The object of this invention is to provide a kind of plastic member, this plastic member is configured to simply, can carry out inexpensively manufacturing and have required rigidity.
A kind of embodiment of the present invention relates to a kind of plastic member, this plastic member has at least one first wall portion, a groove or multiple groove is introduced in the first wall portion, wherein, a groove is formed by the outstanding salient of the plane from described wall portion, wherein, described groove has at least one second wall portion and the 3rd wall portion, wherein, the second wall portion and the plane of the first wall portion become to be greater than directed and the 3rd wall portion and the plane of the first wall portion orientation with becoming to be less than the angle of 45 ° in the angle ground of 45 °.Form such groove thus, these grooves are outstanding from the first wall portion together and therefore formed and be used for the reinforcing portion of raising first wall portion rigidity.
Here particularly advantageously, the plane parallel ground of the 3rd wall portion and the first wall portion is arranged.This makes the second wall portion be arranged on first and the 3rd between wall portion, and the second wall portion is outstanding and therefore produce reinforcement effect from the plane of the first wall portion and the plane of the 3rd wall portion.
Also advantageously, the 3rd wall portion is arranged with the plane of the first wall portion with becoming to be less than the acute angle of 30 °.So can make the second wall portion just part therefore improve rigidity around girth.
In another kind of embodiment also desirably, the plane of the second wall portion and the first wall portion is arranged substantially at a right angle.Therefore very large rigidity is produced.
Also desirably, the 3rd wall portion is arranged with the plane of the first wall portion with becoming to be less than the acute angle of 30 °.The salient connected with the first wall portion with can producing relatively flat like this.
Also advantageously, the second wall portion be designed to around the hole of the first wall portion or edge and the 3rd wall portion closed-loop around the second wall portion.
Particularly advantageously, the second wall portion is designed to connect with three sides in the hole of the first wall portion and the 3rd wall portion connects with the second wall portion in three sides and connects with the first wall portion in side.
Also advantageously, the cross section of groove is designed to triangular in shape.This means, the degree of depth of groove is change in the trend of groove.Therefore, only slight influence can be produced to the flowing along wall portion.
Desirably, if the first wall portion is not designed to flat yet, but arch or bending, so groove follows its arch or bending profile.Groove therefore substantially follow the first wall portion in the shape not having present in groove situation.The trend of this imagination can move towards side extrapolation by groove.
Also desirably, multiple groove distributes around component.Therefore, the whole surface of plastic member is reinforced.
Therefore, here particularly advantageously, groove is arranged along at least one line with distributing.Therefore, particularly can being reinforced along the rigidity of the longitudinal direction of described line of component and the first wall portion.
Also can be advantageously, at least one edge of groove and component be adjacent to arrange.Therefore can realize, improve the reinforcement effect along edge.
Also advantageously, groove has the degree of depth reduced along at least one direction.This can produce Beneficial Effect to along the first wall portion with in the flowing of groove side process.
Also advantageously, plastic member forms flow channel, and fluid can flow through this flow channel along flow direction, and wherein, the degree of depth of groove reduces along flow direction.
In addition desirably, the wall thickness of component is constant substantially.Therefore can realize, the cost of component is optimized and object is the basic purposes meeting component.
Advantageously, do not having to be provided with reinforcing rib in groove and/or region between the grooves yet.This is particularly advantageous, can not arrange on the region of groove if be arranged on by rib.
In a kind of favourable embodiment desirably, groove is along a direction and/or in two directions outstanding from the plane of the first wall portion.Like this, some grooves can be given prominence to along a direction and/or other groove can be given prominence to along another direction.
Here, also particularly advantageously, adjacent groove is holded up in the opposite direction from the plane of the first wall portion.
In another kind of embodiment also advantageously, two adjacent grooves combine together and the regional of corresponding recesses is outstanding from the plane of the first wall portion in the opposite direction.Like this, a unique groove is formed by two adjacent grooves.
Also desirably, component is the manifold of heat exchanger, the housing of heat exchanger or the connection pipe of heat exchanger.
Alternatively, also desirably, component is housing or the housing parts of conditioning unit.
