The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1, an embodiment of the present invention provides a heat exchanger, such as a plate oil cooler, including a heat exchanger body 100, a liquid flow tube 200, and a brazing ring 300. The heat exchanger has the advantages of high connection applicability, capability of ensuring the position degree of the liquid circulating pipe 200 and the like.
Specifically, as shown in fig. 1 and 2, the heat exchanger body 100 includes a plurality of heat exchange plates 110 stacked in sequence, and heat exchange channels 120 are formed between the heat exchange plates 110. Wherein the heat exchanger plate 110 closest to the end is an end plate 111, and the end plate 111 is provided with liquid flow openings 112. In this embodiment, the liquid flow port 112 may be a cooling water inlet or a cooling water outlet. Thus, a liquid such as cooling water can be introduced into the heat exchange channel 120 through the liquid flow port 112, or a liquid such as cooling water in the heat exchange channel 120 can be discharged through the liquid flow port 112. Of course, in other embodiments, the liquid flow port 112 may be an inlet or an outlet for other liquids, and is not limited thereto.
In this embodiment, the liquid circulating pipe 200 may be specifically a cooling water inlet pipe or a cooling water outlet pipe. Of course, in other embodiments, the liquid flowing pipe 200 may be an inlet pipe or an outlet pipe for other liquids, which is not limited to this. One end of the liquid circulation pipe 200 is provided with a mounting boss 210.
Specifically, as shown in fig. 2 to 3, the brazing ring 300 includes a body ring portion 310 and a burring ring portion 320. The body ring portion 310 has a first end 311 and a second end 312. The first end 311 has an outer diameter matching the diameter of the liquid flow port 112 of the heat exchanger and the second end 312 has an inner diameter matching the outer diameter of the liquid flow tube 200. A cuff ring portion 320 is formed at the second end 312. In the present embodiment, the main body ring portion 310 and the burring ring portion 320 are substantially perpendicular to each other, that is, the brazing ring 300 has a T-shaped structure as a whole. The junction of the body ring portion 310 and the cuff ring portion 320 is in a rounded transition 330. One side of the flanged ring portion 320 abuts against the end plate 111, and the other side of the flanged ring portion 320 abuts against the mounting boss 210. In this way, both sides of the burring ring 320 can be brazed with the end plate 111 and the mounting boss 210, so that the liquid circulation pipe 200 can be more stably mounted on the heat exchanger body 100.
In the present embodiment, as shown in fig. 6, the brazing ring 300 is made of a composite material, and the composite material includes a first 4-series aluminum alloy layer 340, a 3-series aluminum alloy layer 350, and a second 4-series aluminum alloy layer 360, which are sequentially stacked, that is, the 3-series aluminum alloy layer 350 is sandwiched between the first 4-series aluminum alloy layer 340 and the second 4-series aluminum alloy layer 360, that is, the inner layer of the brazing ring 300 is made of 3-series aluminum alloy, and the surface layer of the brazing ring 300 is made of 4-series aluminum alloy. The 4-series aluminum alloy has a low melting point, and the use of the 4-series aluminum alloy as the surface layer of the brazing ring 300 is advantageous for brazing the brazing ring 300 to the opening wall of the liquid communication opening 112 and the liquid communication pipe 200. And 3 series aluminum alloy has the characteristic of smaller hardness, and is convenient for pipe expansion deformation after pre-installation. Of course, in other embodiments, the brazing ring 300 may be made of other materials, such as only 3-series aluminum alloy, etc.
In a particular embodiment, as shown in FIG. 5, the outer diameter D1 of the portion of the braze ring 300 proximate the first end 311 is about 19 millimeters, the inner diameter D2 of the portion of the braze ring 300 proximate the first end 311 is about 18 millimeters, and the overall height H of the braze ring 300 is about 1.8 millimeters. The burring ring portion 320 of the brazing ring 300 has a thickness T of about 1.5 mm, and the radius R of the fillet at the junction of the body ring portion 310 and the burring ring portion 320 is about 0.5 mm. Of course, in other embodiments, the size of the brazing ring 300 may also be adjusted according to specific needs, for example, according to the size of the liquid circulation openings 112 and the liquid circulation tubes 200.
Specifically, the outer wall of the brazing ring 300 near the first end 311 is brazed to the port wall of the liquid circulation port 112, the outer wall of the liquid circulation pipe 200 is brazed to the inner wall of the brazing ring 300 near the second end 312, and both sides of the flanged ring 320 are brazed to the end plate 111 and the mounting boss 210, respectively. The liquid circulation pipe 200 is brazed at the liquid circulation port 112 through the brazing ring 300, and the liquid circulation port 112 does not need to be flanged, so that when different liquid circulation ports 112 are met, only the brazing ring 300 with the corresponding size needs to be adopted, the mold opening is not needed, and the applicability is high. Moreover, the liquid circulation port 112 of the heat exchanger is directly used for installation, and the accuracy of the installation position of the liquid circulation pipe 200 can be better ensured without punching and flanging.
Further, the portion of the brazing ring 300 near the first end 311 is in interference fit with the liquid flow port 112, and the liquid flow tube 200 is in interference fit with the portion of the brazing ring 300 near the second end 312. In this way, on the one hand, the strength of the connection of the brazing ring 300 to the heat exchanger can be further increased, and on the other hand, preassembly can also be achieved more easily.
The specific process of installing the liquid circulation pipe 200 in the heat exchanger on the heat exchanger body 100 is as follows:
first, a portion of the brazing ring 300 near the first end 311 is inserted into the liquid circulation port 112, and the liquid circulation tube 200 is inserted into a portion of the brazing ring 300 near the second end 312, with the brazing ring 300 and the mouth wall of the liquid circulation port 112, and the liquid circulation tube 200 and the brazing ring 300 in clearance fit, so as to facilitate the insertion and fit between the brazing ring 300 and the liquid circulation port 112, and between the liquid circulation tube 200 and the brazing ring 300. The liquid flow-through tube 200 is then mechanically expanded so that the liquid flow-through tube 200, the brazing ring 300 and the mouth wall of the liquid flow-through opening 112 are pressed together, thereby achieving a relatively firm preassembly. Finally, the outer wall of the brazing ring 300 near the first end 311 is brazed to the port wall of the liquid circulation port 112, the outer wall of the liquid circulation pipe 200 is brazed to the inner wall of the brazing ring 300 near the second end 312, and both sides of the flanged ring portion 320 are brazed to the end plate 111 and the mounting boss 210, respectively. In this manner, the process of mounting the liquid circulation pipe 200 on the heat exchanger body 100 is completed.
The brazing ring 300 and the heat exchanger have at least the following technical effects:
the brazing ring 300 has a first end 311 having an outer diameter matching the liquid circulation port 112 of the heat exchanger and a second end 312 having an inner diameter matching the outer diameter of the liquid circulation pipe 200, so that when the liquid circulation pipe 200 is installed at the liquid circulation port 112, the portion of the main body ring portion 310 near the first end 311 is directly inserted into the liquid circulation port 112 without being flanged at the liquid circulation port 112, and then the liquid circulation pipe 200 is inserted into the portion of the main body ring portion 310 near the second end 312, thereby performing brazing fixation. Thus, when different liquid circulation ports 112 are met, only the brazing ring 300 with the corresponding size needs to be adopted, mold opening is not needed again, and the applicability is high. Moreover, the liquid circulation port 112 of the heat exchanger is directly used for installation, and the accuracy of the installation position of the liquid circulation pipe 200 can be better ensured without punching and flanging.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
