Description

Integrated control unit for refrigerant module and coolant module

[0001] The present invention relates to an integrated control device for a refrigerant module and a cooling water module, and more particularly, to an integrated control device for a refrigerant module and a cooling water module that is coupled to a refrigerant module but is easily removable.

[0002]

[0003] Typically, automobile engines and transmissions operate at high temperatures due to heat generated by fuel combustion and friction between moving parts. Therefore, an integrated control unit for the refrigerant module and coolant module is crucial to maintain the engine, transmission, and other key components within an appropriate temperature range, ensuring stable vehicle operation.

[0004] Figure 1 is a schematic diagram illustrating an integrated control device for a conventional refrigerant module and a cooling water module.

[0005] Figure 2 is a cross-sectional view of Figure 1.

[0006] As shown in FIGS. 1 and 2, an integrated control device (1) for a refrigerant module and a cooling water module may include a cover (10), a substrate (20), a case (30), and a heat sink (40).

[0007] Specifically, the cover (10) is formed by insert-molding a heat sink (40), and the substrate (20) is bonded to the lower surface of the heat sink (40) to perform the heat dissipation function of the substrate (20). The case (30) may include a plastic material, and while fixing the substrate (20), it is not grounded as an insulator. However, the outer surface of the cover (10) may also include a plastic material, which may cause a problem of vulnerability to radiation noise.

[0008] Meanwhile, coolant flow paths are formed to effectively manage engine and transmission temperatures, and a thermostat regulates the flow to quickly warm up a cold engine. A radiator is installed to dissipate the coolant heat, and a cooling fan is used to improve the radiator's heat exchange performance. The coolant flow paths are typically equipped with valves, which are controlled by an external controller to ensure temperature management. Furthermore, the coolant pump is connected to the controller and its operation is controlled accordingly.

[0009] However, the controller connected to the valve of the coolant path and the coolant pump is usually formed integrally within the housing or connected separately with a wire to the outside of the housing. This wire connection method takes up additional space for the controller connection, and has the problem that the controller is difficult to remove, making maintenance such as A / S complicated.

[0054] Figure 3 is a perspective view showing the combined configuration of an integrated control device according to an embodiment of the present invention.

[0055] Referring to FIG. 3, an integrated control device (100) according to an embodiment of the present invention may be coupled to a refrigerant module (200) and connected to an external power source, a refrigerant module (200), and a coolant module (300). Here, the external power source may be an internal battery power source of an automobile.

[0056] The integrated control device (100) is coupled to the refrigerant module (200), and may be coupled to the top of the refrigerant module (200) for easy attachment and detachment. In addition, the integrated control device (100) is electrically connected to an external power source, a refrigerant module (200), and a cooling water module (300) to control the refrigerant module (200) and the cooling water module (300). The integrated control device (100) may include respective connectors for electrically connecting to the external power source, the refrigerant module (200), and the cooling water module (300). The connectors of the integrated control device (100) may be formed close to each device (the external power source, the refrigerant module (200), and the cooling water module (300)) for easy attachment and detachment.

[0057] Hereinafter, the configuration of the integrated control device (100) will be described in more detail with reference to FIGS. 4 and 5.

[0058] Figures 4 and 5 are perspective views showing the configuration of an integrated control device according to an embodiment of the present invention.

[0059] Referring to FIGS. 4 and 5, an integrated control device (100) according to an embodiment of the present invention includes a case (110) and a heat sink (120), and may include a PCB for controlling a refrigerant module (200) and a cooling water module (300) inside the case (110).

[0060] The integrated control device (100) includes a square case (110), and the case (110) may include a power connector (111) to which an external power source is connected, a coolant module connector (112) connected to a coolant module (300), and a coolant module connector (113) connected to a coolant module (200). The power connector (111) and the coolant module connector (112) may be formed in parallel on one side of the case (110) at a predetermined distance apart from each other. At this time, one side of the case (110) on which the power connector (111) and the coolant module connector (112) are formed may be a side formed in a direction facing the coolant module (300). That is, the coolant module connector (112) may be formed in the direction of the position where the coolant module (300) is arranged, so that it may be more easily connected to the coolant module (300).

[0061] The refrigerant module connector (113) included in the case (110) may be formed on one side adjacent to the other side where the power connector (111) and the coolant module connector (112) are formed. That is, the refrigerant module connector (113) may be formed on the side of the case (110) and connected to the refrigerant module (200). Accordingly, when the integrated control device (100) is connected to all of the external power, the refrigerant module (200), and the coolant module (300), there is no concern about the wires being tangled or confused, and the connection and removal can be easy.

[0062] In addition, the case (110) may form first to third coupling grooves (114_1, 114_2, 114_3) that form fastening holes to be coupled with the refrigerant module (200). The integrated control device (100) may be coupled with the refrigerant module (200) through the first to third coupling grooves (114_1, 114_2, 114_3) formed in the case (110). Here, the first coupling groove (114_1) may be formed between the power connector (111) and the cooling water module connector (112), and the second coupling groove (114_2) and the third coupling groove (114_3) may be formed at a predetermined distance apart from the surface of the case (110) facing the surface where the first coupling groove (114_2) is formed. In the present invention, the location of each coupling groove is limited for convenience of explanation, but the integrated control device (100) may include various embodiments such as the number of coupling grooves, shape of fastening holes, location, etc., depending on the type of refrigerant module (200) to be coupled.

[0063] A heat sink (120) is attached to the upper surface of the case (110) to protect the PCB included in the case (110) and to dissipate heat generated from the PCB. The heat sink (120) includes a grounding portion (121) on one side, and a grounding cable can be connected to one side of the heat sink (120) and the other side of the heat sink (120) and the refrigerant module (200). The integrated control device (100) can prevent leakage of the integrated control device (100) through the grounding portion (121) of the heat sink (120) and the grounding cable connected to the refrigerant module (200).

[0064] Fig. 6 is a cross-sectional view showing a cross-section of an integrated control device according to an embodiment of the present invention;

[0065] Fig. 7 is a cross-sectional view showing a cross-section of an integrated control device according to another embodiment of the present invention.

[0066] Referring to FIG. 6, the integrated control device (100) according to an embodiment of the present invention may further include a cover (170).

[0067] The cover (170) may be made of a plastic material and may surround the outer periphery of the heat sink (120). Accordingly, radiated noise may not be shielded. In addition, the case (110) may also be made of a plastic material and accordingly, radiated noise may not be shielded.

[0068] In conclusion, grounding of the substrate (160) is important to shield radiation noise. At this time, the case (110) cannot serve as a ground, but the heat sink (120) is formed of a conductor and can thus perform heat dissipation and shielding functions.

[0069] In addition, the integrated control device (100) according to an embodiment of the present invention may include a substrate (160) inside a case (110) and a refrigerant module connector terminal (113a) connected to the substrate (160). In FIG. 4, an embodiment in which the substrate (160) and the refrigerant module connector terminal (113a) are connected is illustrated, but it is obvious that the cooling water module connector module and the power connector module are connected to the substrate (160).

[0070] The heat sink (120) is coupled to the upper portion of the case (110), and can be in direct or indirect contact with the substrate (160) to dissipate heat generated from the substrate (160). It is preferable that the heat sink (120) and the substrate (160) are specifically coupled indirectly through a gap filler.

[0071] Additionally, the case (110) can specifically cover the side wall surrounding the substrate (160) and the lower part of the side wall.

[0072] In this way, a structure in which the case (110) surrounds the substrate can be formed, and the heat sink (120) is coupled to the upper part of the case (110) to protect the substrate (160) included inside the case (110) and simultaneously dissipate heat generated from the substrate (160).

[0073] In addition, the present invention may further include at least one SMD (Surface Mount Device) element (180) connected to the substrate (160), as illustrated in FIG. 7. The SMD (Surface Mount Device) element (180) may be connected to the substrate (160) and the heat sink (120), respectively.

[0074] FIG. 8 is a plan view showing an example of an integrated control device according to an embodiment of the present invention being coupled to a refrigerant module.

[0075] Referring to FIG. 8, the integrated control device (100) according to an embodiment of the present invention may further include first to third fastening portions (130_1, 130_2, 130_3) that are coupled to the refrigerant module (200) through first to third coupling grooves (114_1, 114_2, 114_3).

[0076] The first to third fastening portions (130_1, 130_2, 130_3) may be fastened by penetrating the fastening holes of the first to third fastening grooves (114_1, 114_2, 114_3) and a hollow predetermined area of ​​the refrigerant module (200), respectively. The first to third fastening portions (130_1, 130_2, 130_3) may be in the form of bolts. In addition, the first to third fastening portions (130_1, 130_2, 130_3) may include various embodiments depending on the number of the first to third fastening grooves (114_1, 114_2, 114_3), the shape of the fastening holes, etc.

[0077] FIG. 9 is a perspective view showing the configuration of an integrated control device according to another embodiment of the present invention;

[0078] Fig. 10 is a perspective view showing an example of the ground cable of Fig. 9 being connected to the grounding part.

[0079] Fig. 11 is a perspective view viewed from a different direction than Fig. 10.

[0080] Referring to FIGS. 9 to 11, the integrated control device (100) may further include a ground cable (140) having one end connected to a heat sink (120) and the other end connected to a refrigerant module (200). The integrated control device (100) may prevent leakage of the integrated control device (100) through the ground cable connected to a ground portion (121) of the heat sink (120) and an external device (not shown).

[0081] Specifically, the ground cable (140) may include a second through hole (h4, h5) of a predetermined size on at least one of one side and the other side. In addition, correspondingly, the grounding portion (121) may include a second bolting hole (h6) for bolting to the grounding cable (140). Accordingly, the integrated control device (100) of the present invention can prevent leakage of the integrated control device (100) through the grounding cable (140), one side of which is connected to the grounding portion (121) of the heat sink (120) and the other side of which is connected to an external device (not shown). Here, the other side of the grounding cable (140) connected to the external device may be connected to a refrigerant module (200) or a housing or other components, and thus the other side connection of the grounding cable (140) is not limited to any one.

[0082] Fig. 12 is a perspective view showing the configuration of an integrated control device according to another embodiment of the present invention;

[0083] Fig. 13 is a perspective view showing an example of the ground plate of Fig. 12 being connected to a grounding portion.

[0084] The integrated control device (1000) can implement grounding of the vehicle through the grounding portion (121) and the first coupling home (114_1).

[0085] To this end, the present invention may further include a ground plate (150), as shown in FIGS. 12 and 13.

[0086] The ground plate (150) may be coupled to the ground portion (121) on one side and coupled to the first coupling groove (114_1) on the other side. Specifically, the ground plate (150) may include a first through hole (h1, h2) of a predetermined size on at least one of the one side and the other side, as illustrated in FIG. 12.

[0087] In addition, correspondingly, the grounding plate (150) may include a first bolting hole (h3) for bolting to at least one of the grounding portion (121) and the first joining groove (114_1). Accordingly, the grounding plate (150) may be bolted to at least one of the grounding portion (121) and the first joining groove (114_1) regardless of the layout of the vehicle.

[0088] More specifically, the ground plate (150) may include a first ground plate portion (151) formed to a predetermined length and including a first through hole (h1) of a predetermined size at one end, a second ground plate portion (152) formed to extend in a vertical direction from the first ground plate portion (151), and a third ground plate portion (153) formed to extend in a vertical direction from the second ground plate portion (152) but formed in an opposite direction to the first ground plate portion (151). Here, a first through hole (h2) of a predetermined size may be formed at the other end of the third ground plate portion (153), and thus, the ground plate (150) may be coupled to at least one of the ground portion (121) and the first coupling groove (114_1) by a bolting joint.

[0089] In this way, the ground plate (150) is indirectly connected to the SMD element (180) to implement grounding of the vehicle, thereby reducing radiated noise and simplifying the connection. Furthermore, since there is no need to change the ground cable specifications according to changes in vehicle specifications, weight can be reduced, unit costs can be reduced, and assembly ease can be improved.

Therefore, the technical spirit of the present invention includes not only each disclosed embodiment but also a combination of disclosed embodiments, and further, the scope of the technical spirit of the present invention is not limited by these embodiments. In addition, those skilled in the art to which the present invention pertains can make numerous changes and modifications to the present invention without departing from the spirit and scope of the appended claims, and all such appropriate changes and modifications should be considered as equivalents and falling within the scope of the present invention.
