Description
Technical field
The present invention relates to a kind of battery cooling apparatus technical fields, and in particular to one kind is cooling for new energy car battery
Rectangular header and its processing method.
Background technique
The aggravation of the problems such as with environmental pollution and energy shortage, new-energy automobile development are extremely rapid.Currently, new energy
Automobile is broadly divided into pure electric automobile and hybrid vehicle.Power source of the battery as new-energy automobile, in the course of work
It is middle course continuation mileage to be caused insufficient because temperature is excessively high, or even battery is reduced, therefore, as new-energy automobile master
The battery to be cooled down cooling becomes particularly important.Currently, the battery of new-energy automobile is cooling big due to being influenced by battery structure etc.
Mostly cooling using wind cooling method, cooling efficiency is lower.
Summary of the invention
The object of the invention is to overcome the prior art, a kind of rectangular header is provided, by header
The refrigerant or water in portion, the flat tube through being inserted into flat pipe hole cool down the battery of new-energy automobile, and cooling effect is significant, solves
The lower technical problem of cooling efficiency in the prior art.
To achieve the above object, the present invention adopts the following technical scheme: a kind of rectangular header, the header it is transversal
Face be it is rectangular, one side punching have at least two for flat tube insertion flat pipe holes.
Preferably, the flat tube is for the connection between mutual corresponding header and header.
Preferably, transition connection circular arc is respectively set between the adjacent both sides of the rectangular header.
The processing method of above-mentioned rectangular header comprising following steps:
1) it welds circular pipe blank: setting circular pipe blank, high-frequency induction welder welds circular pipe blank；
2) it cleans, dry: being cleaned using aviation kerosine and clean up the surfactant emulsion liquid aluminium slag aluminium skimmings of circular pipe blank, then entering to dry
Dry baking oven is dry；
3) drawing: circular pipe blank is mounted on broaching machine by rectangular pipe mold, the direct drawing squarely pipe in vertical pulling equipment；
4) sawing, cleaning, drying: being sawed into required length for rectangular tube, then falls drawing oil using ultrasonic cleaning, most laggard
Drying oven drying；
5) header forms: rushing flat pipe hole in a side of rectangular tube.
Preferably, the mold is made using hard alloy, and horn mouth expands before external mold calibrating strap.
Preferably, the length of the calibrating strap is 5mm~8mm.
Preferably, the rectangular pipe mold is mounted on broaching machine by adjustable die seat.
Beneficial effects of the present invention are, the invention discloses a kind of rectangular header, two flat tube hole sites are corresponded to each other
Header battery cooler is collectively constituted by flat tube, be not necessarily to fin, the weldering of laggard slice assembled, by inside header
Refrigerant or water, the flat tube through being inserted into flat pipe hole cool down the battery of new-energy automobile, and cooling effect is significant, solves existing
The lower technical problem of cooling efficiency in technology, structure is simple, low in cost, securely and reliably.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
In figure: 1, header, 11, flat pipe hole.
Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, and for explaining only the invention, and is not construed as limiting the claims.
It should be noted that the positional terms such as upper and lower, left and right in the embodiment of the present invention, be only each other relative concept or
Reference that be with the normal operating condition of product be, and should not be regarded as restrictive.
As shown in Figure 1, a kind of rectangular header, the cross section of the header be it is rectangular, the punching of one side has at least two
A flat pipe hole for flat tube insertion, the present embodiment are four flat pipe holes.Flat pipe hole preferentially uses in the same size and same intervals cloth
It sets, the specific number and arrangement of flat pipe hole should be depending on situations such as battery structures, number and cloth of the present invention to flat pipe hole
It sets with no restriction.Two mutual corresponding headers in flat tube hole site collectively constitute battery cooler by flat tube, and flat tube is used for
Connection between header, and flat tube is arranged in internal battery pack, is not necessarily to fin, assembles laggard slice weldering, structure is simple, occupies
Area is smaller.By the refrigerant or water inside header, the flat tube for being inserted into flat pipe hole is cold to the battery progress of new-energy automobile
But, cooling effect is significant.Transition connection circular arc is respectively set between the adjacent both sides of rectangular header, such as left side and upside
Portion (or following side), right side and upper lateral part (or following side).
The processing method of above-mentioned rectangular header comprising following steps:
1) it welds circular pipe blank: setting circular pipe blank, high-frequency induction welder welds circular pipe blank；
2) it cleans, dry: being cleaned using aviation kerosine and clean up the surfactant emulsion liquid aluminium slag aluminium skimmings of circular pipe blank, then entering to dry
Dry baking oven is dry；
3) drawing: circular pipe blank is mounted on broaching machine by rectangular pipe mold, the direct drawing squarely pipe in vertical pulling equipment；
4) sawing, cleaning, drying: (according to requirement of actual working condition) length needed for rectangular tube is sawed into then uses ultrasonic wave
Drawing oil is washed, it is dry that last entering to dry does baking oven；
5) header forms: rushing flat pipe hole in a side of rectangular tube.
Preferably, above-mentioned mold is made using hard alloy, and horn mouth expands before external mold calibrating strap, increases buffering, sizing
The length of band is not easy too long, is preferentially selected as 5mm~8mm；Mold is mounted on broaching machine by adjustable die seat, due to circular pipe blank
Straightness is required stringent, therefore mold base is designed as adjustable die seat, when there is straightness difference in drawing can to mold base into
Row is adjusted, and is adjusted convenient for the four direction of straightness.
Above-mentioned rectangular header should design different specifications according to the difference of battery pack structure.Above-mentioned rectangular header
The setting of circular pipe blank is the most key in the step of processing method.For example, developing a kind of 19mm(long) × 10mm(wide) × 1.0mm
The rectangular header of (wall thickness) specification, length-width ratio is very big, elongated rectangular is easy to break by justifying in drawing, it is therefore desirable to set circle
Shape pipe is easily put into core print in pipe and processing capacity cannot be allowed too big, causes to break, therefore selects 22mm(outer diameter) ×
1.1mm(wall thickness) circular pipe blank progress drawing.
It is that a kind of rectangular header provided by the present invention and its processing method are described in detail above, herein
In apply specific case structural principle and embodiment of the invention be expounded, above embodiments are only intended to help
Understand method and its core concept of the invention；At the same time, for those skilled in the art, according to the thought of the present invention,
There will be changes in the specific implementation manner and application range, in conclusion the content of the present specification should not be construed as to this
The limitation of invention.
