Description

Technology Field

[0001] The present invention relates to a protector assembly device for a heat exchanger, and more specifically, to a protector assembly device for a heat exchanger that allows a protector to be easily mounted on the front surface of a heat exchanger for the protection of the heat exchanger. Background Technology

[0003] Generally, vehicles are equipped with a heating and cooling system including a compressor, condenser, and evaporator for interior heating and cooling, as well as a thermal management system for cooling batteries and Power Electronic (PE) components and recovering waste heat.

[0004] The aforementioned condensers and evaporators, as well as radiators, are manufactured in various structures as a type of heat exchanger.

[0005] Figure 1 attached is a schematic diagram illustrating a conventional heat exchanger and protector connection structure.

[0006] As illustrated in FIG. 1, a conventional heat exchanger (10) is configured to include a pair of header pipes (11), a heat exchanger (12) comprising a plurality of tubes connected to the header pipes (11) and heat dissipation fins mounted between each tube, and a side plate (13) that supports the heat exchanger with a predetermined surface pressure.

[0007] Accordingly, after a high-temperature fluid (refrigerant or cooling water) is supplied to one header pipe (11), heat exchange is performed in which heat is dissipated through the heat dissipation fins as it flows along the tube of the heat exchanger (12), and the low-temperature fluid after heat exchange can be circulated to another part via the other header pipe (11).

[0008] At this time, while the heat exchanger (10) is mounted in the engine room of the vehicle, various foreign substances (e.g., stone fragments, various debris, etc.) may enter the engine room and strike the heat exchanger (12) of the heat exchanger (10), and as a result, external leakage of coolant or refrigerant may occur due to damage to the heat exchanger (12) of the heat exchanger (10).

[0009] To prevent this, a protector (20) that blocks foreign substances is installed on the front of the heat exchanger (10).

[0010] The conventional protector (20) is provided with a structure in which bolt insertion holes (21) are formed at the four corners as shown in FIG. 1, in a square frame mesh structure, and a separate female screw hole (not shown) for bolt fastening is machined on the front of the heat exchanger (10).

[0011] Accordingly, the protector (20) can be attached to the front surface of the heat exchanger (10), and the bolt insertion holes (21) formed at each corner of the protector (20) are aligned with the female screw holes of the heat exchanger (10) in the front and back directions. Then, by inserting a bolt (22) into the bolt insertion holes (21) and fastening it to the female screw holes, the assembly of the protector (20) can be completed, and various foreign substances can be filtered and blocked by the protector (20).

[0012] However, conventional heat exchanger protectors have the following problems.

[0013] First, in order to install a conventional protector, bolt insertion holes must be machined in the protector and female thread holes must be machined in the heat exchanger, and since a worker must perform bolt fastening work in four or more places individually, this results in an increase in the number of assembly processes and parts, and consequently leads to a decrease in assembly workability and an increase in manufacturing costs.

[0014] Second, as conventional protectors are bolted to the heat exchanger, there is almost no clearance between the front of the heat exchanger and the rear of the protector, which results in a problem of space constraints for mounting connection brackets on header pipes, etc.

[0015] For example, when mounting a connecting bracket to a header pipe for assembling the above heat exchanger to a vehicle body, etc., a part of the connecting bracket must be mounted so that it is positioned in the space between the front part of the heat exchanger and the rear part of the protector, but there is a problem that space constraints occur for mounting the connecting bracket because the space between the front part of the heat exchanger and the rear part of the protector is very narrow. The problem to be solved

[0017] The present invention is devised to solve the aforementioned conventional problems and aims to provide a heat exchanger protector assembly device that forms a mounting bar having assembly ends at both the upper and lower sides of the protector, forms an assembly groove in a sealing cap fastened to the header pipe of the heat exchanger, thereby allowing the assembly ends of the mounting bar to be easily assembled by inserting them into the assembly groove of the sealing cap, and secures a clearance space between the front of the heat exchanger and the rear of the protector so that a connecting bracket, etc., for assembling the heat exchanger to a vehicle body, etc., can be easily mounted on the header pipe. means of solving the problem

[0019] To achieve the above-mentioned purpose, the present invention provides a protector assembly device for a heat exchanger comprising: a heat exchanger including a header pipe, a heat exchanger connected to the header pipe in a manner communicable with the header pipe, and a side plate supporting the heat exchanger with a predetermined surface pressure; a sealing cap mounted on an opening of the header pipe; and a protector located on the front of the heat exchanger, wherein a mounting bar having an assembly end protruding downward and upward, respectively, is formed at both the upper and lower sides of the protector, and an assembly groove is formed on the upper and lower sides of the sealing cap to allow the assembly end of the mounting bar to be inserted and mounted.

[0020] In particular, the mounting bar is formed in a right-angle bent shape and is composed of a first horizontal bar extending from both the upper and lower sides of the protector and a second horizontal bar extending from the end of the first horizontal bar toward the heat exchanger, and the assembly end is formed to protrude downward or upward from the end of the second horizontal bar.

[0021] Preferably, a fastening projection is formed on the bottom of the assembly groove, and a fastening groove or fastening hole is formed on the bottom surface of the assembly section.

[0022] Accordingly, when the assembly portion of the mounting bar is inserted and mounted into the assembly groove, the fastening projection is inserted and fastened into the fastening groove or fastening hole.

[0023] In addition, a clearance space is formed between the front portion of the heat exchanger and the rear portion of the protector by the second horizontal bar, a connecting bracket for assembling the heat exchanger is mounted on the header pipe, and a part of the connecting bracket is positioned within the clearance space without interference with the protector.

[0024] In addition, the vertical height of the assembly section of the mounting bar and the vertical depth of the assembly groove are set to a level such that the upper surface of the protector is level with the upper part of the side plate, and a sealing member for preventing backflow of air is mounted on the upper surface of the side plate without interference with the protector. Effects of the invention

[0026] Through the means for solving the above-mentioned problem, the present invention provides the following effects.

[0027] First, by forming a mounting bar having assembly sections at both the top and bottom sides of the protector and forming an assembly groove in a sealed cap that is fastened to the header pipe of the heat exchanger, the assembly section of the mounting bar can be easily assembled by inserting it into the assembly groove of the cap. This eliminates the process of machining bolt insertion holes in the protector and female screw holes in the heat exchanger, as well as the process of a worker fastening bolts in four or more places. Consequently, the number of assembly processes and parts can be reduced, and the workability of assembling the protector can be improved.

[0028] Second, a fastening projection is formed in the assembly groove of the sealing cap, and a fastening groove or fastening hole is formed in the assembly end of the mounting bar. When the assembly end of the mounting bar is inserted and mounted into the assembly groove of the sealing cap, the fastening projection is inserted into the fastening groove or fastening hole, thereby preventing incomplete assembly of the protector and allowing the protector to be fixed without play.

[0029] Third, the mounting bar of the protector is provided in a right-angle bent shape, so that the assembly end of the mounting bar is easily assembled by inserting it into the assembly groove of the cap, thereby creating a clearance space for mounting a connecting bracket between the front part of the heat exchanger and the rear part of the protector, corresponding to a portion of the front-to-rear length of the second horizontal bar of the mounting bar.

[0030] Fourth, when mounting a connecting bracket to a header pipe for assembling a heat exchanger to a vehicle body, etc., a part of the connecting bracket can be positioned in the clearance between the front part of the heat exchanger and the rear part of the protector without interference with the protector, thereby resolving the problem of space constraints for mounting the connecting bracket and making it easy to mount the connecting bracket to the header pipe.

[0037] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0038] Figure 2 attached is an exploded perspective view illustrating a protector of a heat exchanger according to the present invention, and Figure 3 is an assembled perspective view illustrating a protector of a heat exchanger according to the present invention.

[0039] As illustrated in FIGS. 2 and 3, the heat exchanger (100) according to the present invention comprises a pair of header pipes (101, 102) spaced apart from each other, a heat exchanger (103) including a plurality of tubes connected to each header pipe (101, 102) and heat dissipation fins mounted between each tube, and a side plate (104) that supports the upper and lower parts of the heat exchanger (103) with a predetermined surface pressure.

[0040] In addition, a sealing cap (105) for maintaining airtightness of cooling water or refrigerant is attached to the upper opening of the header pipes (101, 102).

[0041] Accordingly, after a high-temperature fluid (refrigerant or cooling water) is supplied to one header pipe (101), heat exchange is performed in which heat is dissipated through the heat dissipation fins as it flows along the tube of the heat exchanger (103), and the low-temperature fluid after heat exchange can be circulated to another part via the other header pipe (102).

[0042] At this time, while the heat exchanger (100) is mounted in the engine room of the vehicle, various foreign substances (e.g., stone fragments, various debris, etc.) may enter the engine room and strike the heat exchanger (103) of the heat exchanger (100), and as a result, external leakage of coolant or refrigerant may occur due to damage to the heat exchanger (103) of the heat exchanger (100).

[0043] To prevent this, a protector (200) that blocks foreign substances is installed on the front of the heat exchanger (100).

[0044] To this end, according to the present invention, a mounting bar (210) is extended and formed with an assembly section (213) protruding from each of the upper and lower sides of the protector (200), and an assembly groove (106) is formed on the upper and lower surfaces of the sealing cap (105) so that the assembly section (213) of each mounting bar (210) is inserted and mounted thereon.

[0045] At this time, a mounting bar (210) extending from both upper sides of the protector (200) has an assembly section (213) protruding downward, and a mounting bar (210) extending from both lower sides of the protector (200) has an assembly section (213) protruding upward.

[0046] In particular, the mounting bar (210) formed at the upper and lower sides of the protector (200) is in a right-angle bent shape as can be clearly seen in FIG. 5, and is composed of a first horizontal bar (211) extending from the upper sides of the protector (200) and a second horizontal bar (212) extending from the end of the first horizontal bar (211) toward the heat exchanger (100), and the first horizontal bar (211) and the second horizontal bar (212) form a right-angle bent arrangement.

[0047] At this time, an assembly section (213) protruding downward is formed on the lower end of the second horizontal bar (212) of the mounting bar (210) extended at both upper sides of the protector (200), while an assembly section (213) protruding upward is formed on the upper end of the second horizontal bar (212) of the mounting bar (210) extended at both lower sides of the protector (200).

[0048] Accordingly, the assembly end (213) of the mounting bar (210) extended at both the upper and lower sides of the protector (200) is inserted and fastened into the assembly groove (106) of the sealing cap (105), thereby allowing the protector (200) to be fixedly arranged in a mounting manner on the front of the heat exchanger (103) of the heat exchanger (100), so that the assembly of the protector (200) can be easily completed, and various foreign substances entering the heat exchanger (100) while driving can be filtered and easily blocked by the protector (200).

[0049] Preferably, as shown in FIG. 4, a fastening projection (107) is formed on the bottom of the assembly groove (106) of the sealing cap (105), and as shown in FIG. 6a and FIG. 6b, a fastening groove (214) or a fastening hole (215) is formed on the bottom or top surface of the assembly section (213) formed on the second horizontal bar (212) of the mounting bar (210).

[0050] Accordingly, when the assembly member (213) formed on the second horizontal bar (212) of the mounting bar (210) is inserted and mounted into the assembly groove (106) of the sealing cap (105), the fastening projection (107) protruding from the bottom of the assembly groove (106) is inserted and fastened into the fastening groove (214) or fastening hole (215) formed on the assembly member (213), thereby allowing the protector (200) to be fixedly arranged in its proper position without shaking.

[0051] In this way, a mounting bar (210) having an assembly section (213) is formed at both the upper and lower sides of the protector (200), and an assembly groove (106) is formed in a sealing cap (105) that is fastened to the header pipe (101, 102) of the heat exchanger (100), so that the assembly section (213) of the mounting bar (210) can be easily assembled by inserting it into the assembly groove (106) of the sealing cap (105). This eliminates the process of machining a bolt insertion hole in the protector and machining a female screw hole in the heat exchanger, and also eliminates the process of a worker fastening bolts in four or more places. Therefore, the number of assembly processes and parts can be reduced, and accordingly, the workability of assembling the protector can be improved.

[0052] Furthermore, by forming a fastening projection (107) on the bottom of the assembly groove (106) of the sealing cap (105) and forming a fastening groove (214) or a fastening hole (215) on the assembly end (213) of the mounting bar (210), so that when the assembly end (213) of the mounting bar (210) is inserted into the assembly groove (106) of the sealing cap (105), the fastening projection (107) is inserted into the fastening groove (214) or the fastening hole (215), thereby preventing incomplete assembly of the protector (200) and allowing the protector (200) to be arranged in a fixed state on the front of the heat exchanger without play or shaking.

[0053] Meanwhile, as shown in FIG. 1, when a conventional protector (20) is mounted to a heat exchanger (10) with a bolt (22), there is almost no clearance between the front part of the heat exchanger (10) and the rear part of the protector (20), which causes a problem of space constraints for mounting a connecting bracket, etc., on a header pipe, etc.

[0054] To resolve this, a space (110) of a predetermined spacing can be formed between the front portion of the heat exchanger (100) and the rear portion of the protector (200) as shown in FIG. 3, corresponding to a portion of the length in the front-rear direction of the second horizontal bar (212) of the mounting bar (210), and due to this space (110), the problem of space constraints for mounting a connecting bracket, etc. on a header pipe, etc. can be resolved.

[0055] To elaborate, the mounting bar (210) of the protector (200) of the present invention is provided in a right-angle bent shape, and the assembly end (213) of the mounting bar (210) is easily assembled by inserting it into the assembly groove (106) of the sealing cap (105), thereby creating a clearance space (110) for mounting a connecting bracket (120) between the front part of the heat exchanger (100) and the rear part of the protector (200) corresponding to a portion of the length in the front-rear direction of the second horizontal bar (212) of the mounting bar (210).

[0056] Accordingly, when a heat exchanger assembly connecting bracket (120) for assembling a heat exchanger to a vehicle body, etc. is mounted on the header pipe (101, 102), a part of the connecting bracket (120) can be positioned within the clearance space (110) without interference with the protector (200), and accordingly, the problem of space constraints for mounting the connecting bracket is resolved, allowing the connecting bracket (120) to be easily mounted on the header pipe.

[0057] Meanwhile, as shown in FIG. 7, a sealing member (130) for preventing backflow of air can be mounted on the upper surface of the side plate (104) without interference with the protector (200).

[0058] More specifically, by setting the vertical height of the assembly section (213) of the mounting bar (210) and the vertical depth of the assembly groove (106) of the sealing cap (105) so that the upper surface of the protector (200) forms a horizontal plane with the upper surface of the side plate (104), a sealing member (130) for preventing backflow of air can be mounted on the upper surface of the side plate (104) without interference with the protector (200).

[0059] Accordingly, the sealing member (130) is positioned in the gap between the upper surface of the side plate (104) and the lower part of the vehicle body (not shown) without being covered by the protector (200), so that the phenomenon of air flowing into the heat exchanger (100) during vehicle operation flowing back to the front of the heat exchanger (100) after passing through the heat exchanger (100) can be easily prevented by the sealing member (130), and the generation of flow noise due to the backflow of air can be prevented.

[0060] Although the present invention has been described in detail above as one embodiment, the scope of the present invention is not limited to the above-described embodiment, and various modifications and improvements by those skilled in the art using the basic concept of the present invention as defined in the following claims are also included within the scope of the present invention.
