Description

Technical Field

[0001] This disclosure relates to a vehicle cooling module, and more specifically, to a vehicle cooling module in which multiple unit modules are connected by means of fasteners and connecting brackets. Background Technology

[0002] Typically, not only components such as the engine used to operate the vehicle are located in the vehicle's engine compartment, but also various heat exchangers such as radiators, intercoolers, evaporators, and condensers used to cool the engine or regulate the air temperature inside the vehicle are also located in the engine compartment. Typically, a heat exchange medium flows within the heat exchanger. The heat exchange medium in the heat exchanger exchanges heat with the outside air present outside the heat exchanger, thus performing a cooling operation or dissipating heat. Therefore, in order to stably operate the various heat exchangers within the vehicle's engine compartment, it is necessary to steadily supply outside air into the engine compartment. In the following text, the heat exchangers configured to cool the vehicle components or the interior of the vehicle as described above are referred to as vehicle cooling modules.

[0003] Typically, a vehicle cooling module may have a structure in which multiple radiators are connected to each other, or a structure in which a fan shroud, condenser, or other components are connected to the radiators. As a related technology, Korean Patent No. 10-1499014 (titled "Radiator") has been filed and registered on May 27, 2015.

[0004] Figure 1 This is a perspective view of a vehicle cooling module in the related art. As shown, the cooling module of the related art has a structure in which a radiator 1 and a unit module 2 are connected to each other by a bracket module 3. The bracket module 3 can be fixed to a box that serves as a rigid member of the radiator 1. The unit module 2 may include a radiator, a condenser, a fan shroud, etc. In this case, to solve the problem of damage, the related art provides a technique that allows the radiator to be used without alteration even if a part of the bracket is damaged, by means of a replaceable bracket.

[0005] As mentioned above, the brackets mounted on the radiator are frequently damaged by external forces. Attempts have been made to address this problem using techniques such as partial replacement. However, because this technique differs from those used to prevent damage, it cannot prevent damage caused by external forces or vibrations. Summary of the Invention

[0006] Technical issues

[0007] The present invention aims to solve the above-mentioned problems. The purpose of the present invention is to provide a vehicle cooling module, which includes a fastening part that pulls a connecting bracket inserted into a hollow part toward the inner wall to prevent the connecting bracket from being damaged by external force or vibration.

[0008] Technical solution

[0009] An example of the present invention provides a vehicle cooling module comprising: a first unit module; and a second unit module, wherein a fastening portion is disposed on the first unit module, and a connecting bracket connected to the fastening portion is disposed on the second unit module, wherein the fastening portion comprises: a receiving member fixed to the first unit module and configured such that the connecting bracket is inserted into the receiving member; and a pressing member fixed to the first unit module and configured to press the connecting bracket inserted into the receiving member, wherein the receiving member has a hollow portion that opens in one direction, and wherein the pressing member has a curved portion having one end fixed to the first unit module and the other end protruding into the hollow portion.

[0010] The receiving member may include a first body, a second body, and a third body, the first body and the second body being connectable, and the second body and the third body being connectable, such that a hook-shaped structure is defined to open to one side, and one end of the first body may protrude further to one side than one end of the third body.

[0011] The curved portion of the pressing member may be configured to be spaced apart from one end of the first body to one side, and the curved portion may be tilted such that the other end of the curved portion points toward the third body.

[0012] The first body may include a first surface contact portion that contacts one surface of the connecting bracket, and the third body may include: a second surface contact portion that contacts another surface of the connecting bracket; and a rib portion that is configured to connect one end of the second surface contact portion to the second body.

[0013] The third body may also include a guide portion connected to the other end of the second surface contact portion and tilted outwards such that the hollow portion on one side is widened.

[0014] The rib portion may have an outwardly curved shape, thereby widening the hollow portion.

[0015] When the connecting bracket is inserted into the receiving member, a predetermined space can be defined between the end of the connecting bracket and the connecting body.

[0016] The connecting bracket can be inserted into one surface side of the third body, and the groove can be recessed inward in the central portion of the other surface of the third body.

[0017] The first unit module may be a heat sink, and the second unit module may be any one of a heat sink, a condenser, and a fan shroud.

[0018] The connecting bracket may include: a main body portion that is at least partially inserted into the receiving member and has a surface configured to be pressed by the pressing member; and a recessed portion that is disposed in at least one of a surface and another surface of the main body portion and can be recessed to a predetermined depth.

[0019] The groove portion can be recessed in a hexagonal shape.

[0020] The groove portion can be located at symmetrical positions on two opposite surfaces of the main body portion.

[0021] Beneficial effects

[0022] The vehicle cooling module of the present invention is configured such that one surface of the curved portion of the connecting bracket inserted into the pressing member is pressed, such that the other surface of the connecting bracket is in close contact with one surface of the third body of the receiving member. Therefore, durability can be improved by preventing gaps from forming with the connecting bracket. Furthermore, vibration durability can be further improved by preventing the fastening portion from being scratched by vibration.

[0023] Furthermore, in the vehicle cooling module of the present invention, the groove can be recessed into the central portion of another surface of the third body of the receiving member, and two protruding portions can protrude from the outer portion of the third body, thereby preventing deformation and damage.

[0024] Furthermore, in the vehicle cooling module of the present invention, a hexagonal groove portion can be formed in the connecting bracket to prevent air bubbles from forming in the vehicle cooling module, thereby improving the performance of the device. Attached Figure Description

[0033] The invention will now be described with reference to the accompanying drawings.

[0034] Figure 2 This is a perspective view of a vehicle cooling module according to an example of the present invention. As shown, the vehicle cooling module of the present invention includes a first unit module 30 and a second unit module 40 connected to each other. A fastening part 10 and a connecting bracket 20 may be respectively provided on the first unit module 30 and the second unit module 40. That is, the fastening part 10 may be provided on one side of the first unit module 30. The connecting bracket 20 may be provided on one side of the second unit module 40, i.e., at a position corresponding to the fastening part 10 provided on one side of the first unit module 30.

[0035] More specifically, the fastener 10 can be connected to the first rigid member 31 of the first unit module 30, and the connecting bracket 20 can be connected to the second rigid member 41 of the second unit module 40. When the first unit module 30 or the second unit module 40 is a radiator, the first rigid member 31 or the second rigid member 41 is configured as a separate member connected to the side housing or the housing itself, such that the positions of the fastener 10 and the connecting bracket 20 can be fixed to the first rigid member 31 or the second rigid member 41. The radiator housing can be made of various materials, such as polypropylene (PP).

[0036] The first unit module 30 and the second unit module 40 can be implemented as various devices. For example, the first unit module 30 can be implemented as a heat sink, and the second unit module 40 can be implemented as a heat sink, a condenser, a fan shroud, etc. Figure 2 An example is shown where both the first unit module 30 and the second unit module 40 are implemented as heat sinks.

[0037] In the following description, the direction in which the first unit module 30 and the second unit module 40 are connected to each other is defined as a forward / backward direction D1. The direction of the first unit module 30, based on the second unit module 40, is defined as a forward direction D. 11 The direction opposite to the forward direction is defined as the backward direction D. 12 Furthermore, the direction in which the tube is spaced apart from the pin-shaped radiator is limited to the upward / downward direction D2. The direction in which the fastener 10 is opened is limited to the upward direction D. 21 The direction opposite to the upward direction is defined as the downward direction D. 22 Furthermore, the direction in which the connecting bracket 20 extends is defined as a left / right direction D3. The direction in which the second unit module 40 is positioned based on the connecting bracket 20 is defined as a left direction D. 31 The direction opposite to the left is defined as the right direction D. 32 .

[0038] Figure 3 It is a perspective view showing the connection state of the fastener and the connecting bracket, and Figure 4 and Figure 5 This is a side view of the fastener.

[0039] Reference Figure 3 The fastening part 10 of the present invention may include a receiving member 100 and a pressing member 200. The main body portion 21 of the connecting bracket 20 may be inserted into and fixed to the receiving member 100.

[0040] The connecting bracket 20 may include a connecting shaft 20a and a main body portion 21, the connecting shaft extending in a left / right direction and having one end fixed to a second rigid member 41 of the second unit module 40, the main body portion being disposed at the other end of the connecting shaft 20a.

[0041] The receiving member 100 may have a hook-like structure that penetrates to the left / right and opens at its upper side. Both the fastening part 10 and the connecting bracket 20 may be made of an olefin-based or amide-based polymer material. For example, both the fastening part 10 and the connecting bracket 20 may be made of polypropylene (PP) or polyamide (PA). As an example of a commercially available product, the fastening part 10 may be made of PP-GF40, while the connecting bracket 20 may be made of PP-GF40 or PA66-GF30.

[0042] When the main body portion 21 of the connecting bracket 20 is inserted into the receiving member 100, the pressing member 200 can be configured to press the main body portion 21 of the connecting bracket 20. That is, when the lower parts of the front and rear surfaces of the main body portion 21 are inserted into the receiving member 100, the pressing member 200 can be configured to press the upper part of the front surface of the main body portion 21. Therefore, the rear surface of the pressing member 200 and the inner rear surface of the receiving member 100 can be in close contact with each other.

[0043] The connecting bracket 20 may also include one or more recessed portions 22, which are disposed and recessed into the front or rear surface of the main body portion 21. The recessed portions 22 can prevent the formation of internal air bubbles.

[0044] Furthermore, the connecting bracket 20 may also include a cover portion 23 that protrudes a predetermined amount along the edge of the main body portion 21. The width of the cover portion 23 in the forward / backward direction may be greater than the width of the main body portion 21 in the forward / backward direction to prevent the main body portion 21 from separating in the left / right direction and to simultaneously or individually limit the insertion depth of the main body portion 21.

[0045] Reference Figure 4 and Figure 5 The receiving member 100 includes a first body 110, a second body 120, and a third body 130 connected to each other. The first body 110 and the second body 120 are connected, and the second body 120 and the third body 130 are connected, such that a hook-shaped structure can be defined that opens at the upper, left, and right sides and closes at the front, rear, and lower sides. That is, the first body 110 and the third body 130 are spaced apart from each other in a forward / backward direction, such that a hollow portion that opens at its upper side can be defined between the first body 110 and the third body 130.

[0046] The first body 110 can be fixed to the first rigid member 31 of the first unit module 30, and the first body 110 has a first height H1 in the upward / downward direction. The second body 120 can extend in the forward / backward direction and connect the first body 110 and the third body 130. The third body 130 can have a second height H2 in the upward / downward direction. In this case, the first height H1 and the second height H2 each correspond to the length in the upward direction based on the bottom 120a, which is the upper surface of the second body 120. In this case, the second height H2 is larger than the first height H1, so that the upper end of the first body 110 can be positioned below the upper end of the third body 130.

[0047] The pressing member 200 may include a bent portion 230 and a fixing portion. The bent portion is spaced apart from the upper side of the first body 110 by a predetermined height (ΔH), and the fixing portion is configured to fix one end of the bent portion 230 to the first rigid member 31. The fixing portion may have various shapes. For example, the fixing portion may include a first fixing portion 210 extending in a forward / backward direction and a second fixing portion 220 extending in an upward / downward direction. Furthermore, the upper end of the bent portion 230 may be fixed to the fixing portion, and the lower end of the bent portion 230 may be positioned closer to the third body 130 than the upper end. That is, the lower end of the bent portion 230 may have a curved or inclined shape toward the third body 130. When the connecting bracket 20 is inserted, the lower end of the bent portion 230 can be pressed forward, so that the bent portion 230 can press the rear side of the connecting bracket 20 by means of repulsive force.

[0048] The third body 130 may include a rib portion 131, a rigid portion 132, and a guide portion 133 sequentially connected to the second body 120. The rib portion 131 may have a shape that bends rearward to a predetermined degree, and the rigid portion 132 may have a shape that extends upward and downward. The guide portion 133 may have a shape that bends rearward or slopes towards its upper end. The rib portion 131 may have a recessed surface 131a recessed inward in its front inner surface. A length corresponding to a first width W1 may be defined between the first body 110 and the innermost side of the recessed surface 131a. The first width W1 may be calculated based on the first surface contact portion 110a of the first body 110. Furthermore, a length corresponding to a second width W2 may be defined between the first surface contact portion 110a and the second surface contact portion 132a, which is the inner surface of the rigid portion 132. In this case, because the rib portion 131 has a rearward-bending shape, the first width W1 may be larger than the second width W2.

[0049] The guide portion 133 can be tilted backward at a first angle θ1 to further facilitate the insertion of the connecting bracket 20. The curved portion 230 can also be tilted upward relative to the reference line at a second angle θ2 at its upper end. In this case, the first angle θ1 can be an acute angle (0° < θ1 < 90°), while the second angle θ2 can be an obtuse angle (90° < θ2 < 180°).

[0050] A portion of the lower end of the curved portion 230 can be positioned at a height corresponding to the second surface contact portion 132a, which is the inner surface of the rigid portion 132. Therefore, the third width W3 can be defined between the portion of the lower end of the curved portion 230 and the second surface contact portion 132a. In this case, because the curved portion 230 has a rearwardly curved shape, the third width W3 can be smaller than the second width W2.

[0051] As described above, the first body 110 and the third body 130 may have a first height H1 and a second height H2 in the upward / downward direction based on the upper surface of the second body 120. The lower end of the curved portion 230 may be configured to be upwardly spaced from the first body 110 by a predetermined height (ΔH). In this case, the rib portion 131, the rigid portion 132, and the guide portion 133 of the third body 130 may each have a second-to-first height H. 21 Height H, 2-2 22 and heights H 2-3 23 In this case, the sum of the first height H1 and the predetermined height (△H) is greater than the second-first height H. 21 and height H of the 2nd-2nd 22 The sum of the two is small, so that a portion of the upper end of the rigid portion 132 and a portion of the lower end of the curved portion 230 can face each other.

[0052] Figure 6 This is a side view showing the fasteners and connecting brackets connected to each other. Figure 7 yes Figure 6 A side view of the cross-section. (Refer to...) Figure 6 and Figure 7 When the connecting bracket 20 is inserted into the fastening part 10, the lower surface of the connecting bracket 20 and the upper surface of the second body 120 are spaced apart from each other, so that the space C can be defined between the lower surface of the connecting bracket 20 and the upper surface of the second body 120. In this case, as described above, the insertion depth of the connecting bracket 20 can be adjusted by the cover portion 23 at the upper end side of the connecting bracket 20. Alternatively, the insertion depth can be limited by a separate stop. Furthermore, the front and rear surfaces of the main body portion 21 of the connecting bracket 20 can be inserted between the first surface contact portion 110a, which is the inner surface of the first body 110, and the second surface contact portion 132a, which is the inner surface of the rigid portion 132. The lower end of the bent portion 230 can press the front surface of the main body portion 21, so that the rear surface of the main body portion 21 can further come into close contact with the second surface contact portion 132a. In this case, a plurality of recessed portions 22 can be recessed into the main body portion 21. Some of the recessed portions 22 can be provided at a height corresponding to the second surface contact portion 132a.

[0053] Figure 8This is an enlarged perspective view of the third main body of the fastening component. (Refer to...) Figure 8 The connecting bracket 20 can be inserted into the front side of the third body 130, i.e., the hollow portion 100a, and the central portion of the rear surface of the third body 130 can be recessed inward. Therefore, the third body 130 can include a groove 130a and a pair of protrusions 130b. The groove is recessed inward in the central portion of the rear surface of the third body and extends in an upward / downward direction. The pair of protrusions 130b are respectively located on the left and right sides of the groove 130a and protrude rearward. Therefore, deformation and damage caused by tension can be prevented, thereby improving the durability of the device.

[0054] Figure 9 This is a front view showing one end of the connecting bracket. (Refer to...) Figure 9 One or more recessed portions 22 provided on the main body 21 can be at least hexagonal in shape. In this case, the multiple recessed portions 22 can be arranged to be spaced apart from each other in the upward / downward or left / right direction. The hexagonal recessed portions 22 can prevent the formation of internal air bubbles. Therefore, the vehicle cooling module can be used for a longer period of time, and the maintenance cost of the cooling module can be reduced.

[0055] This invention is not limited to the embodiments described above, and its application scope is diverse. Of course, any person skilled in the art can make various modifications and implementations without departing from the subject matter of the invention as claimed in the claims.
