In order to make those skilled in the art person understand the utility model scheme better, the utility model is described in further detail below in conjunction with drawings and embodiments.
Please refer to Fig. 2 to Fig. 5, Fig. 2 provides the structural representation of a kind of specific embodiment of collector tube for the utility model embodiment; Fig. 3 is a collector tube shown in Figure 2 through the horizontal cross-sectional schematic of heart protuberance wherein; Fig. 4 is the front elevational schematic of collector tube shown in Figure 2; Fig. 5 is vertical cross-sectional schematic of collector tube shown in Figure 2.
In a kind of specific embodiment, collector tube 2 provided by the utility model can be made by metal or metal alloy, is more commonly processed by aluminum pipe.
The sidewall of collector tube 2 is provided with at least one radiating tube interface 21, and the radiating tube (not shown) is fixedlyed connected with collector tube 2 by radiating tube interface 21; Both fixedly connected modes are generally welding, and particularly, both can be brazed in one.Obviously, the number of described radiating tube should equate with the number of radiating tube interface 21; Usually be provided with in parallel to each other between the described radiating tube, and preferably all perpendicular to collector tube 2.All keep between collector tube 2 and the described radiating tube being communicated with, so that heat transfer medium is mobile therein.Certainly, collector tube 2 also should comprise the flow channel and the flow pass of heat transfer medium in case of necessity.
In order to realize sufficient heat exchange as much as possible, usually the heat transferring medium circulation passage in the heat exchanger need be made as the snakelike of bending, therefore some lateral partitions grooves 22 need be set in collector tube 2, and plug-in mounting dividing plate 25 (being shown among Fig. 5) therein, septalium 22 should guarantee wherein can insert described dividing plate fully at collector tube 2 horizontal width.Obviously, in order to form the circulation passage of described bending, all septaliums 22 all should be located between the radiating tube interface 21, and each septalium 22 should be arranged in two collector tubes of heat exchanger interlacedly.
Septalium 22 and radiating tube interface 21 best centers are arranged at the both sides of collector tube 2 symmetrically, bring very big facility can for like this plug-in mounting of dividing plate 23.Certainly, change the position that is provided with of septalium 22, make its suitable angle of central shaft rotation, also be fine around collector tube 2.
Be provided with center protuberance 23 between the two adjacent radiating tube interfaces 21, obviously, center protuberance 23 is the strip that is parallel to radiating tube interface 21 substantially.
When a plurality of otch of Surface Machining of collector tube 2, above-mentioned angle R can play good positioning action; In addition, the formation of above-mentioned angle R can guarantee that the radiating tube interface cuts in the mould travelling backwards process, and radiating tube interface 21 can not produce deformation, has significantly improved the machining accuracy of radiating tube interface 21.Therefore the reliability of heat exchanger provided by the utility model can be significantly improved.
In order to obtain further technique effect, can carry out some improvement to the collector tube that the above-mentioned specific embodiment provided.
Such as, above-mentioned scope by left side face 231 and inclined plane, right side 232 formed angle R should be further selected rightly.
If above-mentioned angle R is excessive, it will not have the location and will prevent that radiating tube interface 21 from producing the effect of deformation.If above-mentioned angle R is too small, then can produces material stress or form stamping defect.
Therefore, as shown in Figure 3, in the concrete embodiment of another kind, can be further be set to 120 degree to 175 degree by the scope of left side face 231 and inclined plane, right side 232 formed angle R.Can guarantee that like this collector tube to be processed in the process has enough clamping forces, be convenient to control the dimensional accuracy and the alteration of form of collector tube, have higher reliability in the operating process that a plurality of described radiating tubes while plug-in mountings are gone into the radiating tube interface.
On the other hand, the width on above-mentioned left side face 231 and inclined plane, right side 232 also should be chosen rightly.
