[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It will be understood that the specific embodiments described herein are only used to explain the relevant inventions, rather than to limit the invention. The described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present invention.

[0033] As can be seen from the background technology, the purpose of the present invention is to reduce the cost of a stamping machine and the process capacity.

[0034] See also Figures 1 to 4 , Figure 8-Figure 9 , the present invention discloses a processing device, comprising:

[0035] The first mold 200 includes a first template 210, a second template 220, a first punch 230 and a push rod assembly 240. The first punch 230 is fixed to the first template 210 and corresponds to the first through hole 221 of the second template 220 to perform a punching action; the push rod assembly 240 is arranged in the first through hole 221 of the second template 220 to perform a lifting action; when the first mold 200 is in the first working mode, the first punch 230 punches according to the first size; the push rod assembly 240 performs a lifting action.

[0036] The second mold 300 includes a third template 310, a fourth template 320 and a second punch 330. The second punch 330 is fixed to the third template 310 and corresponds to the second through hole 321 of the fourth template 320 to perform a punching action. When the second mold 300 is in the second working mode, the second punch 330 punches according to a second size, wherein the second size is smaller than the first size.

[0037] In the processing equipment of the embodiment of the present invention, when the first mold 200 performs the first working mode, a blind hole 110a of a first size can be punched out on the mounting plate 110; when the second mold 300 performs the second working mode, a corner hole 110b of a second size can be further punched out on the mounting plate 110. It can be seen that the processing equipment provided by the present invention can realize the processing of the mounting plate 110 by using two processes, thereby reducing the processing processes of the mounting plate 110 and improving the process capacity.

[0038] The processing equipment is used to process the mounting plate 110. When the mounting plate 110 is installed in the first processing position 222 of the second template 220 and the first mold 200 is in the first working mode, the first punch 230 punches the first end face 112 of the mounting plate 110 according to the first size to form a blind hole 111a on the first end face 112 and form a protrusion 115 located at the first through hole 221 on the second end face 113; the push rod assembly 240 pushes up the protrusion 115 to separate the protrusion 115 from the first through hole 221, and the mounting plate 110 is separated from the second template 220.

[0039] When the mounting plate 110 is installed in the second processing position 322 of the fourth template 320, and the second mold 300 is in the second working mode, the second punch 330 punches the first end face 112 of the mounting plate 110 and the corresponding position of the blind hole 111a, or punches the second end face 113 of the mounting plate 110 and the corresponding position of the blind hole 111a according to the second size, and punches the waste into the second through hole 321 to form a corner hole 111b on the mounting plate 110, wherein the second size is smaller than the first size. The second mold 300 may also be provided with a second ejector assembly (not shown in the figure), the structure of the second ejector assembly is substantially the same as that of the ejector assembly 240, and the second ejector assembly is used to eject the waste from the second through hole 321, so as to facilitate the cleaning of the equipment. Of course, in other embodiments, the second mold 300 may not be provided with a second ejector assembly.

[0040] When the processing equipment of the present invention processes the mounting plate 110, when the first mold 200 is in the first working mode, the blind hole 111a is processed on the first end surface 112 of the first mounting plate 110; when the second mold 300 is in the second working mode, the final processing of the corner hole 111b is completed. It can be seen that the processing equipment provided by the present invention can realize the processing of the mounting plate 110 by using two processes. Thereby reducing the processing cost of the mounting plate 110 and improving the process capacity.

[0041] It should be noted that the first die 200 and the second die 300 are arranged on the same punching machine, or the first die 200 and the second die 300 can be arranged on two punching machines respectively, the first die 200 is arranged on the first punching machine 400, and the second die 300 is arranged on the second punching machine 500. In the first case, when processing the blind hole 111a, the punching machine cooperates with the first die 200 to perform the first working mode; when processing the corner hole 111b, the first die 200 is replaced by the second die 300 in the same punching machine, and the punching machine cooperates with the second die 300 to perform the second working mode. In the second case mentioned above, the first die 200 is arranged on the first punch 400, and the second die 300 is arranged on the second punch 500. When processing the blind hole 111a, the first punch 400 cooperates with the first die 200 to perform the first working mode; when processing the corner hole 111b, the second punch 500 cooperates with the second die 300 to perform the second working mode.

[0042] It should be noted that the processing equipment can respectively execute the first working mode and the second working mode continuously, or can execute the first working mode and the second working mode sequentially.

[0043] Taking the continuous execution of the first working mode and the second working mode as an example, by repeatedly executing the first working mode, the preliminary processing of multiple mounting plates 110 can be completed; after the preliminary processing of all mounting plates 110 is completed, the second working mode is repeatedly executed to complete the precision processing of the corner holes 111b of multiple mounting plates 110.

[0044] Taking the execution of the first working mode and the second working mode in sequence as an example, this is suitable for processing a mounting plate 110. The mounting plate 110 is placed at the first processing position 222, and the first working mode is executed to complete the preliminary processing of the mounting plate 110; the mounting plate 110 is placed at the second processing position 322 of the fourth template 320, and then the second working mode is executed to complete the precise processing of the corner hole 111b of the mounting plate 110.

[0045] It can be seen that the processing equipment disclosed in the embodiment of the present invention is easy to mass-produce, and its processing logic is relatively simple and easy to control.

[0046] Further, when the first mold 200 is arranged on the first punch 400 and the second mold 300 is arranged on the second punch 500; the first punch 400 includes an upper support plate 410, a first mold frame 420, a first pad 430, a first punch fixing plate 440, and a second mold frame 450 arranged in sequence from top to bottom, wherein the first template 210 is fixed to the first mold frame 420 through the first punch fixing plate 440 and the first pad 430; the first punch 230 is fixed to the first punch fixing plate 440 and is arranged corresponding to the first through hole 221; the second template 220 is arranged on the second mold frame 450; the push rod assembly 240 is fixed to the second mold frame 450 and corresponds to the first through hole 221 of the second template 220.

[0047] When the mounting plate 110 is installed in the first processing position 222 and the first mold 200 executes the first working mode, the upper support plate 410, the first mold frame 420, the first pad 430 and the first punch fixing plate 440 cooperate with the first mold plate 210, and the second mold frame 450 and the first mold angle 460 cooperate with the second mold plate 220, so that the first mold plate 210 and the second mold plate 220 can be molded together.

[0048] The first punch 230 punches the first end surface 112 of the mounting plate 110 according to the first size to form a blind hole 111 a on the first end surface 112 and a protrusion 115 located at the first through hole 221 on the second end surface 113 .

[0049] When the first mold 200 executes the first working mode, the upper support plate 410, the first mold frame 420, the first pad 430 and the first punch fixing plate 440 cooperate with the first mold plate 210, the second mold frame 450 and the first mold angle 460 cooperate with the second mold plate 220, and the first mold plate 210 and the second mold plate 220 are separated.

[0050] The push rod assembly 240 pushes up the protrusion 115 to make the protrusion 115 leave the first through hole 221 and separate the mounting plate 110 from the second template 220 .

[0051] The ejector assembly 240 is used to realize the stripping of the mounting plate 110 and the second template 220. In some embodiments of the present invention, the ejector assembly 240 includes an ejector 241, a screw plug 242 and a spring 243, wherein the ejector 241 can be slidably arranged in the mounting hole 451 of the second mold frame 450 and the first through hole 221 of the second template 220, the screw plug 242 is fixed to the outer periphery of the ejector 241, the outer diameter of the screw plug 242 is larger than the inner diameter of the first through hole 221, and the spring 243 is located above the spring 243; the spring 243 is located in the mounting hole 451 of the second mold frame 450 to drive the ejector 241 to perform the lifting action. During the separation process of the first template 210 and the second template 220, the ejector 241 moves upward under the elastic force of the spring 243 and pushes the protrusion 115 out of the first through hole 221, further separating the mounting plate 110 from the second template 220.

[0052] In order to reduce the maintenance cost, the second template 220 includes a second template body 220a and a first insert 220b, the first through hole 221 is arranged on the first insert 220b, and the first insert 220b is detachably arranged on the second template body 220a. When the first insert 220b is damaged or the error of the first through hole 221 is large, it can be replaced by another first insert 220b without replacing the entire second template 220, thereby reducing the maintenance cost. It should be noted that the above-mentioned detachable connection is a bolt connection, or a clamping connection, or a screw connection, and any connection method that can realize the detachment of the first insert 220b can be understood as a detachable connection.

[0053] Further, when the first mold 200 is arranged on the first punch 400 and the second mold 300 is arranged on the second punch 500; the second punch 500 includes a third die frame 510, a second pad 520, a second punch fixing plate 530, a stop plate 540, a third pad 550 and a fourth die frame 560 arranged in sequence from top to bottom, wherein the third template 310 is fixed to the third die frame 510 through the stop plate 540, the second punch fixing plate 530 and the second pad 520; one end of the second punch 330 is fixed to the second punch fixing plate 530, and the other end of the second punch 330 passes through the stop plate 540 and is arranged corresponding to the second through hole 321 of the fourth template 320; the fourth template 320 is fixed to the fourth die frame 560 through the third pad 550.

[0054] When the mounting plate 110 is installed in place at the second processing position 322 and the second mold 300 executes the second working mode, the third mold frame 510, the second pad 520, the second punch fixing plate 530 and the stop plate 540 cooperate with the third template 310, and the third pad 550 and the fourth mold frame 560 cooperate with the fourth template 320 to make the third template 310 and the fourth template 320 close together.

[0055] The second punch 330 punches at the position of the blind hole 111a of the first end surface 112 of the mounting plate 110 according to the second size, or punches at the position corresponding to the blind hole 111a of the second end surface 113 of the mounting plate 110, and punches the waste into the second through hole 321 to form a corner hole 111b on the mounting plate 110.

[0056] The third die frame 510 , the second pad 520 , the second punch fixing plate 530 and the stop plate 540 cooperate with the third template 310 , and the third pad 550 and the fourth die frame 560 cooperate with the fourth template 320 to separate the third template 310 from the fourth template 320 .

[0057] In order to optimize the above technical solution, the second punching machine 500 further includes a second die angle 570 and a lower support plate 580, and the second die angle 570 is located between the fourth die frame 560 and the lower support plate 580. By setting the second die angle 570 and the lower support plate 580, the height of the second mold 300 can be compensated, and products of different heights can be processed. Among them, the second die angle 570 is made of soft materials, such as rubber, soft plastic, etc.

[0058] In order to reduce the maintenance cost of the fourth template 320, the fourth template 320 includes a fourth template body 320a and a second insert 320b, the second through hole 321 is arranged on the second insert 320b, and the second insert 320b is detachably arranged on the fourth template body 320a. When the second insert 320b is damaged or the error of the second through hole 321 is large, it can be replaced by another second insert 320b without replacing the entire fourth template 320, thereby reducing the maintenance cost. It should be noted that the above-mentioned detachable connection is a bolt connection, or a clamping connection, or a screw connection, and any connection method that can achieve the detachable connection of the first insert 220b can be understood as a detachable connection.

[0059] It should be noted that in the first mold 200 , the number of first processing positions 222 is one or more, and one first processing position 222 is used to process one mounting plate 110 . In the second mold 300 , the number of second processing positions 322 is one or more, and one second processing position 322 is used to process one mounting plate 110 .

[0060] In some embodiments of the present invention, the number of the processing position is one, and one processing position is used to install one mounting plate 110 . Figure 1 and Figure 2 The disclosed processing equipment includes a first processing station 222 , and the first processing station 222 is used to process a mounting plate 110 . Figure 3 and Figure 4 The disclosed processing equipment includes a second processing position 322, and a second processing position 322 is used to process a mounting plate 110. Of course, the above processing positions are only examples. In the embodiment of the present invention, there can be other numbers of processing positions, which does not constitute a specific limitation here.

[0061] In order to further optimize the above technical solution, see Figure 5 The processing equipment also includes a detection component 700 and a controller 600. The detection component 700 is used to detect the detection parameters of the mounting plate 110, detect the position of the mounting plate 110 at the processing station, and determine whether the mounting plate 110 is placed in place; the first in-place switch 710 controller 600 is used to control the first mold 200 to execute the first working mode and / or control the second mold 300 to execute the second working mode when the detection parameters meet the preset requirements. By setting the controller 600 and the detection component 700, automatic processing can be achieved, thereby improving the production capacity efficiency of the processing equipment.

[0062] The detection component 700 can be a pressure sensor or an in-place switch. When the detection component 700 includes an in-place switch in the present invention, the detection component 700 includes a first in-place switch 710 and a second in-place switch 720. When the first in-place switch 710 is triggered, the controller 600 controls the first mold 200 to execute the first working mode; when the second in-place switch 720 is triggered, the controller 600 controls the second mold 300 to execute the second working mode. The first in-place switch 710 and the second in-place switch 720 are arranged at corresponding positions of the first processing position 222 and the second processing position 322, and respond to the structure of the mounting plate 110. When the mounting plate 110 is installed in place at the first processing position 222, the mounting plate 110 can trigger the first in-place switch 710; when the mounting plate 110 is installed in place at the second processing position 322, the mounting plate 110 can trigger the second in-place switch 720. In other words, when the first in-place switch 710 is triggered, it means that the mounting plate 110 is in place at the first processing position 222; when the second in-place switch 720 is triggered, it means that the mounting plate 110 is in place at the second processing position 322. Of course, the above examples are only based on the in-place switch, and the detection component 700 is not limited to the case where it only includes the in-place switch.

[0063] To further optimize the above technical solution, the processing equipment of the present invention is also configured with a third working mode and a fourth working mode, wherein the third working mode includes continuously executing the first working mode; and the fourth working mode includes continuously executing the second working mode. When the condition of the third working mode is triggered, the processing equipment can execute the third working mode to continuously process the blind holes 111a of the plurality of mounting plates 110; when the condition of the fourth working mode is triggered, the processing equipment can execute the fourth working mode to continuously process the corner holes 111b of the mounting plate 110.

[0064] Since the processing equipment can continuously execute the first working mode and the second working mode, the processing equipment control method in the embodiment of the present invention can also control the processing equipment to continuously execute the first working mode, or control the processing equipment to continuously execute the second working mode.

[0065] See also Figure 6 The embodiment of the present invention discloses a method for processing a mounting plate, wherein the mounting plate 110 has a first end surface 112 and a second end surface 113 disposed opposite to the first end surface 112; the processing method comprises the following steps:

[0066] Step S1: Determine whether the mounting plate 110 is installed in place at the first processing position 222. If so, the processing equipment is in the first working mode.

[0067] It can be determined that the mounting plate 110 is installed in place at the first processing position 222 by setting a detection component 700 to detect that the mounting plate 110 is installed in place at the first processing position 222. The above-mentioned detection component 700 can be implemented by setting a position sensor, an in-place switch or an image collector; specifically, the first processing position 222 of the processing equipment can be provided with a plurality of position sensors, and when all position sensors generate position signals, the mounting plate 110 is installed in place. Alternatively, the first processing position 222 of the processing equipment can also be provided with a plurality of in-place switches, and when the in-place switches generate in-place signals, the mounting plate 110 is installed in place. Alternatively, the processing equipment is provided with an image collector to collect an image of the first processing position 222, and when the image of the mounting plate 110 is collected, the mounting plate 110 is installed in place. Alternatively, it is also possible to determine whether the mounting plate 110 is installed in place by visual observation.

[0068] The first working mode specifically includes the following steps:

[0069] The first punch 230 punches the first end surface 112 of the mounting plate 110 according to the first size to form a blind hole 111 a on the first end surface 112 and a protrusion 115 that flows into the first through hole 221 on the second end surface 113 .

[0070] Figure 7(a) shows the situation when the blind hole 111a is not processed on the mounting plate 110, and the first end surface 112 and the second end surface 113 of the mounting plate 110 are arranged opposite to each other, wherein the first end surface 112 is used to connect the mounting plate 110 with the counterpart, and the second end surface 113 is used to connect with the end plate 120 of the heat exchanger 100; see Figure 8 (a) shows a diagram of the mounting plate 110 being mounted on a processing device, with the first end face 112 of the mounting plate 110 facing upward, and the blind hole punched material 114 flowing toward the second end face 113 to form a protrusion 115, as shown in FIG. Figure 8 (b).

[0071] Figure 7 (b) shows the installation plate 110 after processing the blind hole 111a and the corner hole 111b. The material 114 punched out of the blind hole flows to the second end surface 113 to form a protrusion 115. The blind hole 111a can be processed by punching, drilling, milling and other processing methods. In the embodiment of the present invention, punching is preferably selected. The corner hole 111b can be processed by punching, drilling, milling and other processing methods. In the embodiment of the present invention, punching is preferably selected.

[0072] The ejector assembly 240 ejects the protrusion 115 , ejects the protrusion 115 from the first through hole 221 , and separates the mounting plate 110 from the second template 220 .

[0073] Step S2: Determine whether the mounting plate 110 is installed in place at the second processing position 322. If so, the processing equipment is in the second working mode.

[0074] To determine whether the mounting plate 110 is installed in place at the second processing position 322, a detection component 700 may be provided to detect whether the mounting plate 110 is installed in place at the second processing position 322. The detection component 700 may be implemented by providing a position sensor, an in-place switch or an image collector; specifically, the second processing position 322 of the processing equipment may be provided with a plurality of position sensors, and when all position sensors generate position signals, the mounting plate 110 is installed in place. Alternatively, the second processing position 322 of the processing equipment may also be provided with a plurality of in-place switches, and when the in-place switches generate in-place signals, the mounting plate 110 is installed in place. Alternatively, the processing equipment may be provided with an image collector to collect images of the second processing position 322, and when the image of the mounting plate 110 is collected, the mounting plate 110 is installed in place.

[0075] The second working mode includes the following steps:

[0076] The second punch 330 punches the second end surface 113 of the mounting plate 110 at positions corresponding to the blind hole 111 a according to a second size, so that the waste flows out of the first end surface 113 to form a corner hole 111 b, and the second size is smaller than the first size.

[0077] It should be noted that before the second working mode, the mounting plate 110 needs to be turned over and the mounting plate 110 needs to be installed in place at the second processing position 322 of the fourth template 320 .

[0078] Figure 7 (b) and Figure 7 (c) shows the front view and side view of the mounting plate 110 in which the corner hole 111b is processed. Figure 7 (b) and 7 (c) show the situation after the blind hole 111a and the corner hole 111b are processed on the mounting plate 110, and the material 114 punched out of the blind hole flows to the second end surface 113 to form a protrusion 115. The blind hole can be processed by stamping, drilling, milling and other processing methods. In the embodiment of the present invention, the stamping processing method is preferably selected. The corner hole 111b can be processed by stamping, drilling, milling and other processing methods. In the embodiment of the present invention, the stamping processing method is preferably selected.

[0079] 8(b) and Figure 8 (c) shows a schematic diagram after flipping the mounting plate 110, wherein the second end face 113 of the mounting plate 110 faces upward, and the second punch 330 punches according to the second size. It should be noted that the second size is the finishing size of the corner hole 111b, which can be adjusted according to the specifications of the heat exchanger 100.

[0080] The embodiment of the present invention discloses another method for processing a mounting plate. The mounting plate 110 has a first end surface 112 and a second end surface 113 disposed opposite to the first end surface 112. The processing method comprises the following steps:

[0081] Step S1: Determine whether the mounting plate 110 is installed in place at the first processing position 222. If so, the processing equipment is in the first working mode.

[0082] It is judged that the mounting plate 110 is installed in place at the first processing position 222 by setting a detection component for detecting that the mounting plate 110 is installed in place at the first processing position 222. The above-mentioned detection component 700 can be implemented by setting a position sensor, an in-place switch or an image collector; specifically, the first processing position 222 of the processing equipment can be provided with a plurality of position sensors, and when all position sensors generate position signals, the mounting plate 110 is installed in place. Alternatively, the first processing position 222 of the processing equipment can also be provided with a plurality of in-place switches, and when the in-place switches generate in-place signals, the mounting plate 110 is installed in place. Alternatively, the processing equipment is provided with an image collector to collect an image of the first processing position 222, and when the image of the mounting plate 110 is collected, the mounting plate 110 is installed in place.

[0083] The first working mode specifically includes the following steps:

[0084] The first punch 230 punches the first end surface 112 of the mounting plate 110 according to the first size to form a blind hole 111 a on the first end surface 112 and a protrusion 115 that flows into the first through hole 221 on the second end surface 113 .

[0085] Figure 7 (a) shows the situation when the mounting plate 110 is not processed with a blind hole, and the first end face 112 and the second end face 113 of the mounting plate 110 are arranged opposite to each other, wherein the first end face 112 is used to connect the mounting plate 110 to the counterpart, and the second end face 113 is used to connect to the end plate 120 of the heat exchanger 100; see Fig. 9 (a) shows a diagram of the mounting plate 110 being mounted on a processing device, with the first end face 112 of the mounting plate 110 facing upward and the blind hole punching material 114 flowing toward the second end face 113. Fig. 9 (b).

[0086] The ejector assembly 240 ejects the protrusion 115 , ejects the protrusion 115 from the first through hole 221 , and separates the mounting plate 110 from the second template 220 .

[0087] Step S2: Determine whether the mounting plate 110 is installed in place at the second processing position 322. If so, the processing equipment is in the second working mode.

[0088] To determine whether the mounting plate 110 is installed in place at the second processing position 322, a detection component 700 may be set to detect whether the mounting plate 110 is installed in place at the second processing position 322. The above detection component 700 may be implemented by setting a position sensor, an in-place switch or an image collector; specifically, the second processing position 322 of the processing equipment may be provided with a plurality of position sensors, and when all position sensors generate position signals, the mounting plate 110 is installed in place. Alternatively, the second processing position 322 of the processing equipment may also be provided with a plurality of in-place switches, and when the in-place switches generate in-place signals, the mounting plate 110 is installed in place. Alternatively, the processing equipment may be provided with an image collector to collect images of the second processing position 322, and when the image of the mounting plate 110 is collected, the mounting plate 110 is installed in place.

[0089] The second working mode includes the following steps:

[0090] The second punch 330 punches at the blind hole 111a according to the second size to make the waste flow out of the second end surface 113 and form a corner hole 111b; the second size is smaller than the first size. It should be noted that before this working mode, there is no need to flip the mounting plate 110, and the mounting plate 110 can be directly installed in place at the second processing position 322 of the fourth template 320.

[0091] Figure 7 (c1), Figure 7 (c2) and Fig. 9(c) shows a case where the mounting plate 110 is processed with a corner hole 111b.

[0092] Fig. 9 (b) and Fig. 9 (c) shows a schematic diagram of the solution without flipping the mounting plate 110, wherein the first end face 112 of the mounting plate 110 faces upward, and the second punch 330 punches according to the second size. It should be noted that the second size is the finishing size of the corner hole 111b, which can be adjusted according to the specifications of the heat exchanger 100.

[0093] See also Figures 10 to 12 The present invention discloses a mounting plate 110, which includes a blind hole 111a and a corner hole 111b. The blind hole 111a is located at the first end surface 112 of the mounting plate 110, and the corner hole 111b is located at the mounting plate 110. The blind hole 111a and the corner hole 111b penetrate the first end surface 112 and the second end surface 113 of the mounting plate 110. The corner hole 111b of the embodiment of the present invention adopts Figures 6 to 9 The mounting plate is processed by the processing method shown.

[0094] See also Fig.13 and Fig.14 The present invention discloses a heat exchanger 100, comprising a mounting plate 110, an end plate 120 and a heat exchange plate 130 stacked together, wherein a corner hole 111b of the mounting plate 110 is aligned with a first corner hole 121 of the end plate 120, wherein the corner hole 111b of the mounting plate 110 is provided with a connecting pipe 140 extending along the stacking direction, the connecting pipe 140 extends into the first corner hole 121 of the end plate 120 and is connected to the mounting plate 110, and an end of the connecting pipe 140 extending into the first corner hole 121 of the end plate 120 is higher than the end surface of the end plate 120 away from the mounting plate 110.

[0095] In the heat exchanger 100 of the embodiment of the present invention, the pipe 140 extending along the stacking direction is arranged at the corner hole 111b of the mounting plate 110, the pipe 140 extends into the first corner hole 121 of the end plate 120 and is connected to the mounting plate 110, and one end of the pipe 140 extending into the first corner hole 121 of the end plate 120 is higher than the end surface of the end plate 120 away from the mounting plate 110. Therefore, when the heat exchanger 100 is put into the furnace, the solder flows, and since one end of the pipe 140 extending into the first corner hole 121 of the end plate 120 is higher than the end surface of the end plate 120 away from the mounting plate 110, the solder will not leave a flow mark at the mouth of the corner hole 111b of the mounting plate 110, thereby reducing the generation of the flow mark and improving the product quality.

[0096] It should be noted that the mounting plate 110 has a first end face 112 and a second end face 113 disposed opposite to each other, wherein the first end face 112 and the second end face 113 are close to the end plate 120, wherein the second end face 113 is used to connect the mounting plate 110 to the counterpart, and the first end face 112 is used to connect to the end plate 120 of the heat exchanger 100. The corner hole 111b of the mounting plate 110 passes through the first end face 112 and the second end face 113.

[0097] The pipe 140 is embedded in or riveted to the mounting plate 110, so that the pipe 140 is connected to the mounting plate 110. When the pipe 140 is embedded in the mounting plate 110, the outer wall of the pipe 140 is tightly fitted or interference fit with the corner hole 111b of the mounting plate 110. By adopting a tight fit or interference fit, the pipe 140 and the mounting plate 110 are connected as one body. Therefore, when the heat exchanger 100 using the mounting plate 110 is put into the furnace, the solder will not flow from the pipe 140 to the corner hole 111b of the mounting plate 110.

[0098] In order to ensure the aesthetics of the heat exchanger 100, the end of the pipe 140 close to the mounting plate 110 is flush with the end surface of the mounting plate 110 away from the end plate 120. In some embodiments of the present invention, the end of the pipe 140 close to the mounting plate 110 may be recessed in the end surface of the mounting plate 110 away from the end plate 120. In some embodiments of the present invention, the end of the pipe 140 close to the mounting plate 110 may also protrude from the end surface of the mounting plate 110 away from the end plate 120.
