Description
The present invention relates to a kind of plastic water collection cabin, it is suitable for constituting the part of H Exch, especially the part of car heat exchanger.
The collecting chamber of this pattern claims again by " water tank ", comprises the base layer structure that a plastics forming is made.This base layer structure mainly comprises a formation hydroecium body and the outer wall that can be covered by a water collection sheet (claim again " orifice plate "), and the end of pipe group is inserted on the described water collection sheet.
A kind of such collecting chamber should have the favorable mechanical performance, so that the opposing impact, and can be assembled together by the leg and the described water collection sheet of water collection sheet, the water collection sheet leg closes up against the root of collecting chamber.
On the other hand, a kind of such collecting chamber should be able to be resisted the pressure and temperature of the heat transfer fluid of this H Exch of flowing through.
When a kind of such H Exch was used as the warming device of mechancocaloric cooling vessel or automobile passenger cabin, heat transfer fluid normally contained the water of glycol, can reach about 120 to 130 ℃ temperature.H Exch, especially collecting chamber should be able to be resisted even may reach 150-200 ℃ temperature.
Another problem that collecting chamber involves be these collecting chambers also should resist special under the effect of heat transfer fluid by the caused damage of hydrolytic action.
The current most of plastic water collection cabins that use on H Exch are homogenous materials, make with polyamide.The advantage of this plastics is to have high impact strength.Opposite, the shortcoming of this plastics is that hydrolytic resistance can be poor.In order to overcome this shortcoming, be necessary to strengthen the wall thickness of collecting chamber, with its inside face of avoiding contacting with heat transfer fluid owing to breaking or too early fatigue that hydrolysis even local hydrolysis produce.
On the other hand, it also is on record using the collecting chamber of phenylene polysulfide material, because this special plastic material has opposing advantage by the caused damage of hydrolytic action under the heat transfer fluid effect.Unfortunately, the impact strength of this plastics is low.
Here it is the general preferred use polyamide material of people, that strengthen base layer structure thickness, especially strengthen the reason of the collecting chamber of the chamber wall thickness that its inside face contacts with heat transfer fluid.
In addition, another shortcoming of known this collecting chamber is the cost height of used plastics, and especially for phenylene polysulfide collecting chamber, its material cost almost is three times of polyamide hydroecium cost.
On the other hand, after the FR-A-2461916 patent disclosure, people have known that this composite material comprises the supporting layer of one deck acieral and the lining of the another kind of acieral of one deck with a kind of composite material making H Exch, and the latter is used for the opposing corrosion.
Yet this material is suitable for making the H Exch of soldering,, is suitable for the different technology of H Exch a kind of and the machinery assembling that is, and the collecting chamber of the H Exch of machinery assembling is made with plastics.
Purpose of the present invention is specially in order to overcome above-mentioned shortcoming.
For this reason, the present invention proposes a kind of collecting chamber that is used for H Exch, this collecting chamber has the base layer structure of a plastic.
According to the present invention, this base layer structure is provided with the liner of one deck chemical inert material, is suitable for forming between the heat transfer fluid in the base layer structure and the H Exch of flowing through a chemical barrier layer.
Like this, collecting chamber of the present invention the interliner of the base layer structure of plastics and a chemical inert material together.
The selection of the plastics of base layer structure mainly is to consider its mechanical characteristics, especially shock resistance.
As for chemical inert material, needn't require it self to have the favorable mechanical performance.Its selection is its chemical inertness, so that constructed one deck chemical barrier layer between the heat transfer fluid of the base layer structure and the H Exch of flowing through, stops damage because of the caused base layer structure of hydrolytic action with this.
In the preferred a kind of form of implementation of the present invention, base layer structure is with a kind of plastics manufacturing, especially a kind of thermoplastic material manufacturing with good mechanical properties.
As an example, this plastics especially can be selected from polypropylene and polyamide.
In this, preferably using polypropylene is than polyamide, particularly more economical than phenylene polysulfide because of its cost.
Advantageously add reinforcing material, for example glass fibre in the plastics of base layer structure.
In a kind of preferred implementing form of the present invention, the plastics of base layer structure are a kind of glass fibre enhanced polypropylene, and the content of glass fibre accounts for the 10%-60% of weight.Used glass fibre can be a long fibre, or chopped fiber.
Preferably a kind of plastics of the liner of collecting chamber of the present invention especially a kind ofly are suitable for resisting the thermoplastic material that may reach 150-200 ℃ of temperature.This plastics should have chemical inertness for heat transfer fluid.
As an example, lining can use the phenylene polysulfide to make, and this is a hydrolytic resistance energy of considering this special material.
And that the phenylene polysulfide has is easy to use, the advantage of molding especially, and have can with the compatible advantage of in making the H Exch collecting chamber, using of those plastics.
Because base layer structure has guaranteed the mechanical characteristics of collecting chamber basically, so the thickness of liner can be very little, so also lowered cost, particularly under the situation of the higher phenylene polysulfide of material cost, this becomes very important advantage.
In general, the thickness of liner is less than 1 millimeter, preferably less than 0.5 millimeter.
Collecting chamber of the present invention can be made with various manufacture methods.
First method adopts the injection molding base layer structure on the liner that exists with form of film.
Can be attached to the model bottom surface to this film and inject the plastics that are used to constitute base layer structure then this moment.
As an example, the thickness minimum of base layer structure can be 2 millimeters, and the thickness minimum of liner is 0.2 millimeter.
Second method, base layer structure and liner adopt two injection moulding moldings.This means that base layer structure and liner material separately is actually injection molded simultaneously.
In this case, advantageously, the thickness minimum of base layer structure is 2 millimeters, and the minimum thickness of liner is 0.4 millimeter.
In the second approach, the minimum thickness of liner is in principle greater than the minimum thickness in the first method of making liner with the form of film that pre-exists.
In the description as an example, with accompanying drawing as a reference, unique accompanying drawing is the front partial section view that has biopsy cavity marker devices that is equipped with the H Exch of collecting chamber of the present invention hereinafter.
The represented H Exch of this figure comprises that mechanically is assembled to the plastic water collection cabin 1 on the metal water collection sheet 2.This water collection sheet claims again " orifice plate ", admits the end that constitutes the pipe group and cross the many water pipes 3 of numerous radiating gills 4.
