Description

Technical Field

[0001] This utility model relates to the field of heat exchangers, and in particular to a high-strength heat exchanger structure. Background Technology

[0002] The heat exchanger's structure consists of welded end caps at both ends of the core. During operation, the distribution of the medium in the heat exchanger exhibits a certain temperature difference, and there is also a temperature difference between the internal temperature of the structure and the external ambient temperature.

[0003] Because the high-strength heat exchanger structure needs to withstand large temperature differences, the structure of the heat exchanger is subject to varying degrees of deformation, making the end caps prone to damage.

[0004] Furthermore, because the core and the end cap are directly connected by welding around the edge, the connection strength is relatively weak, making the welded joint prone to leakage.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a high-strength heat exchanger structure to solve the problems in the prior art where the structure is subjected to different degrees of deformation, making the end caps easy to break and the connection strength is weak, making the welded position prone to leakage.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] A high-strength heat exchanger structure;

[0009] Includes: a main body; end caps, disposed opposite each other on both sides of the main body; and a connector, communicating with the end caps;

[0010] The main body has steps on both sides, and a mounting piece is connected to the end cap; the end cap is fastened to the steps, and the mounting piece is inserted between the main body and the end cap and connected to the main body.

[0011] A further technical solution is that a fixing piece is formed on the main body near the step; the mounting piece connects to the fixing piece.

[0012] A further technical solution is to form a notch on the end cap near the main body; the mounting piece is inserted into the notch.

[0013] A further technical solution is that side plates extend from both sides of the mounting plate, and limiting members are provided on the side plates; the side plates are connected to the fixing plate; and the limiting members are inserted into the notch.

[0014] A further technical solution is to connect reinforcing ribs to the end cap, and the reinforcing ribs are connected to the mounting plate.

[0015] A further technical solution is that a space is formed inside the end cap, the space forms a curved surface, and reinforcing strips are formed at the corners of the curved surface; the reinforcing strips connect the end cap.

[0016] A further technical solution is that the end cap includes a curved plate bent along the curved surface, a straight plate disposed within the curved plate, and end plates sealing both ends of the space; wherein the end plates connect the curved plate and the straight plate; the curved plate forms extension plates on both sides of the straight plate, and the extension plates are fastened to the step.

[0017] A further technical solution is that the step forms a groove; the extension plate is bent and embedded in the groove.

[0018] A further technical solution is to form mounting ears along both sides of the joint; the pipe is fixed to the joint by a fastener, and the fastener is screwed into the mounting ear.

[0019] Compared with the prior art, the beneficial technical effects of this utility model are as follows: (1) The end cap is installed on the step by a snap-fit ​​method, which makes it convenient to disassemble and assemble the end cap; the mounting piece is inserted between the main body and the end cap to complete the restriction of the mounting piece. At the same time, the mounting piece completes the restriction by insertion and does not connect the main body and the end cap, and does not restrict the deformation of the main body and the end cap. There will be no leakage between the main body and the end cap; the mounting piece completes the first method of fixation by connecting the main body, and then completes the second method of fixation by inserting into the main body and the end cap. The two fixing methods work at the same time, which improves the structural strength of the connection between the main body and the end cap.

[0020] (2) When installing the end cap, the curved position of the extension plate is embedded into the groove, and the sliding end cap is moved to the preset position of the step; the end cap is prevented from falling out of the step by embedding the curved position of the extension plate into the groove; the reinforcing strips connect the curved plate and the straight plate respectively to ensure the firmness of the connection position between the two; at the same time, since the curved plate is a curved structure, the curved plate is reinforced by the reinforcing strips.

[0021] (3) The right-angled sides of the reinforcing ribs are connected to the end cap and the mounting plate respectively, and the stability of the triangle is used to strengthen the structure of the mounting plate.

[0022] (4) The mounting ears increase the thickness of the left and right positions of the connector. Mounting holes are formed on the mounting ears. The depth of the mounting holes in the front and back directions is relatively long. When the fastener thread is screwed into the mounting hole, the threaded connection of the fastener is relatively stable and the fastener will not loosen when fixing the pipe.

[0030] Figure 1 A schematic diagram of the high-strength heat exchanger structure of the first embodiment of this utility model is shown. Figure 2 A schematic diagram of the structure of the right end of the end cap according to the first embodiment of this utility model is shown. Figure 3 This diagram shows a right-side view of the end cap according to the first embodiment of the present invention. (In conjunction with...) Figures 1-3 As shown, this utility model discloses a high-strength heat exchanger structure.

[0031] The high-strength heat exchanger structure includes: a main body 1, end caps 2 disposed on the upper and lower sides of the main body 1, and a connector 3 connecting the end caps 2.

[0032] The main body 1 has steps 11 on its upper and lower sides, and mounting pieces 4 are connected to the left and right ends of the end cap 2. The end cap 2 is fastened onto the steps 11, and the mounting pieces 4 are inserted between the main body 1 and the end cap 2 and connected to the main body 1.

[0033] The end cap 2 is installed on the step 11 using a snap-fit ​​method, facilitating its assembly and disassembly. The mounting piece 4 is inserted between the main body 1 and the end cap 2, thus providing restraint. However, since the mounting piece 4 is inserted without connecting the main body 1 and the end cap 2, it does not restrict deformation of either component, preventing leakage between them. The mounting piece 4 achieves the first method of fixation by connecting to the main body 1, and the second method by inserting into the main body 1 and the end cap 2. These two methods work simultaneously, increasing the structural strength of the connection between the main body 1 and the end cap 2.

[0034] A fixing piece 12 is formed on the main body 1 near the step 11, and the mounting piece 4 is connected to the fixing piece 12.

[0035] For example, the fixing piece 12 is connected to the main body 1 in the front-to-back direction, or the fixing piece 12 is set in the left-to-right direction and bent before being connected to the main body 1, so as to adapt to the requirements of the installation space.

[0036] A notch 21 is formed on the end cap 2 near the main body 1, and the mounting piece 4 is inserted into the notch 21.

[0037] Notch 21 is located near the fixing piece 12. The mounting piece 4 is inserted into notch 21 to prevent the end cap 2 from becoming loose.

[0038] Side plates 41 extend from the front and rear sides of the mounting plate 4, and the upper end of the side plates 41 is connected to the mounting plate 4. A limiting member 42 is provided on the side plates 41.

[0039] The side piece 41 is connected to the fixing piece 12. The connection methods include, but are not limited to: welding the side piece 41 and the fixing piece 12, connecting the side piece 41 and the fixing piece 12 with bolts and nuts, and applying fixing glue between the side piece 41 and the fixing piece 12.

[0040] The cross-section of the notch 21 is angular, and after the limiting member 42 is inserted into the notch 21, it completes the restriction on the end cap 2. The cross-sectional shape of the notch 21 includes, but is not limited to, triangle, quadrilateral, semicircle, and sector.

[0041] A space 22 is formed in the left-right direction inside the end cap 2. A curved surface 23 in the front-back direction is formed at the upper end of the space 22. The front and back ends of the curved surface 23 bend downward. A reinforcing strip 24 is formed at the corner of the curved end of the curved surface 23. The reinforcing strip 24 is set in the left-right direction and connects to the end cap 2.

[0042] The end cap 2 includes a curved plate 25 bent along a curved surface 23, a straight plate 26 disposed within the curved plate 25, and end plates 27 at both ends of the sealing space 22. The front and rear ends of the straight plate 26 are connected to the inner surface of the curved plate 25. The edges of the end plates 27 are connected to both the curved plate 25 and the straight plate 26. Extension plates 28 are formed on both sides of the curved plate 25 towards the straight plate 26, and the extension plates 28 are fastened to the steps 11.

[0043] Step 11 forms a groove 13, which is formed on the front and back sides of step 11 in the left and right directions. Extension plate 28 bends toward groove 13 and is embedded in groove 13.

[0044] During installation, the curved portion of the extension plate 28 is inserted into the groove 13, and the sliding end cap 2 is moved to the preset position of the step 11. By inserting the curved portion of the extension plate 28 into the groove 13, the end cap 2 is prevented from coming off the step 11.

[0045] The reinforcing strip 24 connects the curved plate 25 and the straight plate 26 respectively, ensuring the firmness of the connection between the two. At the same time, since the curved plate 25 has a curved structure, the reinforcing strip 24 strengthens the curved plate 25.

[0046] Second embodiment:

[0047] Figure 4 A schematic diagram of the high-strength heat exchanger structure according to the second embodiment of this utility model is shown. The second embodiment differs from the first embodiment in that:

[0048] The end cap 2 is connected to the reinforcing rib 5, and the reinforcing rib 5 is connected to the mounting plate 4.

[0049] For example, the reinforcing rib 5 is triangular. The right-angled sides of the reinforcing rib 5 are connected to the end cap 2 and the mounting plate 4 respectively, and the stability of the triangle is used to strengthen the structure of the mounting plate 4.

[0050] Third embodiment:

[0051] Figure 5 A schematic diagram of the high-strength heat exchanger structure according to the third embodiment of this utility model is shown. The third embodiment differs from the second embodiment in that:

[0052] Mounting ears 31 are formed on both sides of the connector 3, extending in the front-to-back direction. The pipe is fixed to the connector 3 by a fastener 6, which is threaded into the mounting ears 31. The mounting ears 31 increase the thickness of the connector 3 at the left and right positions. Mounting holes are formed on the mounting ears 31, with a relatively long depth in the front-to-back direction. When the fastener 6 is threaded into the mounting hole, the threaded connection of the fastener 6 is more stable, and the fastener 6 will not loosen when fixing the pipe.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
