Description

Technical Field

[0001] This utility model relates to the field of heat exchangers, and more specifically, to a plate-fin stacked heat exchanger that is easy to produce quickly. Background Technology

[0002] Currently, oil-water heat exchangers, water-water heat exchangers, and cryogenic coolers in automotive and industrial heating systems are mainly stamped stacked heat exchangers. The main components of stacked heat exchangers are all machined using stamping dies, requiring extremely high precision. This results in very high demands on the molds, leading to high mold processing costs and processing cycles that can easily take one to two months, resulting in significant time costs. Furthermore, the selling price of these stacked heat exchangers is very low. Therefore, this approach is feasible when mass production is possible. However, for small-batch production or in the initial design stage, using molded parts would be too wasteful. Therefore, a plate-fin stacked heat exchanger that can be easily and quickly produced is needed. Utility Model Content

[0017] Example: Please see Figure 1-4 A plate-fin stacked heat exchanger that is easy to manufacture quickly includes a substrate 1, and also includes... The partition plate 4 and the surrounding plate 5 are located above the substrate 1. There are several partition plates 4 and surrounding plates 5, and the partition plates 4 and surrounding plates 5 are arranged in pairs and adjacent to each other upwards. A cover plate 2 is placed on the top surface of the partition plate 4 at the top. The cover plate 2 and the surface of the substrate 1 are provided with corresponding threaded connecting pipes 3. The partition plate 4 includes a plate body 401, and each of the four corners of the plate body 401 is provided with a flow hole 402. The surface of the plate body 401 is also integrally formed with positioning protrusions 403. There are four positioning protrusions 403, which are divided into two groups. The protrusion directions of the two groups of positioning protrusions 403 are respectively set in opposite directions. Specifically, the positive and negative settings of the positioning protrusion 403 allow it to simultaneously perform positioning and installation operations on two adjacent plates 501 and their surface flow holes 502, greatly improving installation time. Meanwhile, the partition plate 4 adopts a double composite structure to connect the upper and lower structures and is used to separate fluids. The flow hole 402 can be a round hole, a square hole, an oblong hole, or a similar irregular hole. The enclosure 5 includes a second plate 501, a second flow hole 502 is formed on the surface of the second plate 501, a positioning groove 503 is formed on the surface of the second plate 501, a finned plate 504 is fixedly installed on the inner wall of the second plate 501, a third flow hole 505 is formed on the surface of the finned plate 504, the shapes of the third flow hole 505 and the second flow hole 502 are adapted to the shape of the first flow hole 402, the position and size of the positioning groove 503 are adapted to the position and size of the positioning protrusion 403, and the shape of the second plate 501 is adapted to the shape of the first plate 401; Specifically, the surrounding plate 5 mainly functions to seal the perimeter, sealing the outer perimeter of the two adjacent partition plates 4 to form a flow channel cavity. The built-in finned plate 504 can accelerate heat exchange inside the flow channel cavity. In addition to finned structures, the finned plate 504 can also adopt a similar nail plate structure, which is the same as the setting of the first flow hole 402. The second flow hole 502 and the third flow hole 505 can also be round holes, square holes, oblong holes, or similar irregular holes, as long as they are consistent with the first flow hole 402. Finally, the positioning groove 503 can be used to coordinate with the positioning protrusion 403 of the second plate 501 to complete the quick docking and fixing of the surrounding plate 5 and the partition plate 4, improving the assembly speed and assembly convenience, while also ensuring accurate alignment and sealing.

[0018] The working principle of this utility model is as follows: First, plate 1 401 is aligned with the top surface of substrate 1 through positioning protrusion 403 to complete the docking. Then, plate 2 501 is docked with the positioning protrusion 403 surface of bottom plate 1 401 through flow hole 2 502 to complete the positioning docking. Next, a new plate 1 401 is docked above plate 2 501. This process is repeated. Finally, cover plate 2 is positioned and docked with the top surface of the top plate 1 401 through positioning protrusion 403, and then fixed.

[0019] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
