Abstract
Description
Cooling unit of the vehicle in which the telematics module is placed
[0001] The present invention relates to a cooling device for a vehicle. A specific embodiment relates to a cooling device for a vehicle in which a telematics module is disposed.
[0002] Recently, the need to provide communication services through vehicles has been increasing. To provide these services, vehicles must be equipped with telematics modules. As vehicle telematics modules become increasingly high-performance, the communication modules used in these modules also need to be implemented with high performance and high integration.
[0003] The high performance and high integration of communication modules in vehicle telematics modules lead to increased heat generation within these components. When in operation, the telematics module mounted on a vehicle generates extremely high temperatures. Furthermore, the telematics module installed in a vehicle can be exposed to high-temperature ambient conditions. This increased temperature significantly impacts the reliability of the communication modules and components within the telematics module.
[0004] Meanwhile, when using fans to dissipate heat generated by components, the noise generated by the fan may cause sensitivity in vehicle occupants, depending on its location within the vehicle. Furthermore, when installed in an electric vehicle, the fan noise may be perceived as even louder.
[0005] Therefore, it is necessary to apply fanless thermoelectric coolers (TECs) to telematics modules, communication modules, and other components to eliminate fan noise and ensure the longevity, operation, and temperature reliability of these modules and components. In this regard, a cooling device must be designed that takes into account the temperatures of the electronic components within the telematics module.

[0057] Below, an antenna module according to the present specification is described in detail. In this regard, FIG. 1 is a drawing illustrating a vehicle according to an embodiment of the present specification.
[0058] Referring to FIG. 1, a vehicle (1) may be equipped with at least one communication antenna. The vehicle (1) may transmit and / or receive signals of various frequency bands using the communication antenna. The vehicle (1) may perform communication such as V2V (Vehicle-to-Vehicle), V2I (Vehicle to Infrastructure), V2P (Vehicle-to-Pedestrian), and V2N (vehicle-to-network).
[0059] The above antenna may be composed of a substrate made of a material such as PET (polyethylene terephthalate) and an antenna pattern formed on the substrate. For example, the antenna may be a transparent antenna.
[0060] The above antenna may be placed on the glass of the vehicle (1). The antenna may be coupled or attached to a front windshield (101), door glass (102, 103), quarter glass (104), rear windshield (not shown), side mirror (not shown), sunroof (105), or lamp glass (106). For example, the antenna may be a transparent antenna. As another example, the antenna may be placed in an area where a roof (110) is formed on the upper portion of the vehicle (1).
[0061] Meanwhile, FIGS. 2A and 2B illustrate a structure in which an antenna module can be mounted in a vehicle including an antenna module mounted in a vehicle according to the present specification.
[0062] Referring to Figures 2a and 2b, the present specification proposes a planar antenna that does not protrude, replacing the existing shark fin antenna, to improve the appearance of an automobile (vehicle) and preserve telematics performance in the event of a collision. Furthermore, the present specification proposes an antenna that integrates an LTE antenna and a 5G antenna, taking into account 5th generation (5G) communications, along with the provision of existing mobile communication services (LTE).
[0063] Referring to Fig. 2a, an antenna module (1000) is placed on a formed roof of a vehicle (1). In Fig. 2a, a radome (110a) may surround the antenna system (1000) to protect the antenna module (1000) from the external environment and external impacts during vehicle operation. The radome (110a) may be made of a dielectric material through which radio signals transmitted / received between the antenna system (1000) and infrastructure structures such as base stations or other vehicles may be transmitted.
[0064] Referring to FIG. 2b, the antenna module (1000) may be arranged within the roof structure (110b) of the vehicle (1), and may be configured such that at least a portion of the roof structure (110b) is implemented as a non-metal. At this time, at least a portion of the roof structure (110b) of the vehicle may be implemented as a non-metal, and may be made of a dielectric material through which radio signals transmitted / received between the antenna system (1000) and infrastructure such as a base station or other vehicles may be transmitted.
[0065] Meanwhile, referring to FIGS. 2a and 2b, the region where a beam pattern is formed by an antenna provided in an antenna module (1000) mounted on a vehicle needs to be formed from a horizontal region to an upper region by a predetermined angle.
[0066] In this regard, the peak of the elevation beam pattern of the antenna provided in the antenna module (1000) does not need to be formed at the bore site. Therefore, the peak of the elevation beam pattern of the antenna needs to be formed from the horizontal region to an upper region by a predetermined angle. For example, the elevation beam pattern of the antenna may be formed in a hemisphere shape as shown in FIGS. 2A and 2B. In addition, since the beam peak is formed within a low elevation angle range (e.g., 30 degrees), the elevation beam pattern of the antenna may be referred to as a low elevation beam pattern.
[0067] FIG. 3 is a configuration diagram of a vehicle according to an embodiment of the present specification. Referring to FIG. 3, the vehicle (1) may include an object detection device (410), a communication device (420), a user interface device (431), a driving operation device (432), a vehicle driving device (433), a driving system (434), a navigation system (435), a sensing unit (436), an interface unit (437), a memory (438), a power supply unit (439), and / or a control unit (440).

For example, the object detection device (410) may include a processor (411), a camera (412), a radar (413), a lidar (414), an ultrasonic sensor (415), and / or an infrared sensor (416).
[0069] The communication device (420) may be a device for performing communication with an external device. The communication device (420) may include at least one of a transmitting antenna, a receiving antenna, an RF (Radio Frequency) circuit or an RF element capable of implementing various communication protocols for performing communication. For example, the communication device (420) may include a processor (421), a short-range communication unit (422), a location information unit (423), a V2X communication unit (424), an optical communication unit (425), a broadcast transceiver unit (426), and / or an ITS communication unit (427).
[0070] The user interface device (431) may be a device for interaction between the vehicle (1) and a user. The vehicle (1) may implement a UI (User Interface) or UX (User Experience) through the user interface device (431).
[0071] The driving control device (432) may be a device that receives user input for driving. The vehicle driving device (433) may be a device that electrically controls the operation of various devices within the vehicle (1). The driving system (434) may be a system that controls various operations of the vehicle (1). The navigation system (435) may provide navigation information. The sensing unit (436) may sense the status of the vehicle (1).
[0072] The interface unit (437) can serve as a passageway for various types of external devices connected to the vehicle (1). The memory (438) can store basic data for the units of the vehicle (1), control data for controlling the operation of the units, input / output data, etc. The power supply unit (439) can supply power required for the operation of each component. The control unit (440) can control the overall operation of each unit within the vehicle (1). The control unit (440) can be implemented as an ECU (Electronic Control Unit) and / or a TCU (Telematics Control Unit).
[0073] Meanwhile, referring to FIGS. 1 to 3, the antenna system mounted on a vehicle may be positioned inside the vehicle, on the vehicle roof, inside the roof, or inside the roof frame. In this regard, the antenna system disclosed in this specification may be configured to operate in the low band (LB), mid band (MB), and high band (HB) of a 4G LTE system and the SUB6 band of a 5G NR system.
[0074] Meanwhile, a telematics module mounted on a vehicle according to the present specification will be described. The substrates placed inside the vehicle antenna module can have electronic components placed on both the first and second surfaces, thereby reducing the size occupied by the substrates. In particular, the NAD (Network Access Device) substrate, in which electronic components for 5G wireless communication are placed, can be implemented as a double-sided substrate. The NAD substrate implemented as a double-sided substrate can be formed with a double-sided heat dissipation structure. Meanwhile, the reduced-size NAD substrate can be placed on the main PCB in an optimal layout.

[0076] Referring to FIGS. 4 and 5, a cooling device of a vehicle in which a telematics module according to the present specification is installed is described. The telematics module (1000) may be installed between a metal frame (9) of the vehicle and a non-metallic roof cover (1030). Electronic components of the telematics module (1000) may be installed in the space between the lower cover (1020) and the upper cover (1010).
[0077] The cooling device (2000) may be configured to include a telematics module (1000), a heat dissipation module (1600), and a heat-conducting connector (1600c). The telematics module (1000) may be disposed in a space between the lower cover (1020) and the upper cover (1010). The telematics module (1000) may include a PCB (1200) and a plurality of heat-generating components disposed in different areas of the PCB (1200).

Referring to FIG. 5, the plurality of heat generating components may include a first heat generating module (1300), a second heat generating component (1400), and a third heat generating module (1350). The third heat generating module (1350) may include a processor (1350) such as an MCU.
[0078] The heat dissipation module (1600) can be configured to form a cooling surface (S1) and a heating surface (S2) depending on the operation of the driving voltage. The heat dissipation module (1600) can be placed on one side of a metal roof cover (1030) of a vehicle in which the telematics module (1000) is placed.
[0079] A thermal conductive connector (1600c) may be configured to connect a cooling surface (S1) of a heat dissipation module (1600) and at least one heat generating module. The thermal conductive connector (1600c) may be configured to include a plurality of heat wires to connect at least one heat generating module. Heat generated from at least one heat generating module may be configured to be dissipated through the cooling surface (S1) of the heat dissipation module (1600) via the thermal conductive connector (1600c).
[0080] At least a part or all of the heat dissipation module (1600) may be disposed outside the telematics module (1000) and connected to the heat dissipation component inside the module by a heat-conducting connector (1600c). At least a part or all of the heat dissipation module (1600) may be disposed outside the case formed by the lower cover (1020) and the upper cover (1010) and connected to the heat dissipation component inside the module by a heat-conducting connector (1600c). The heating surface (S2) of the heat dissipation module (1600) may be configured to dissipate heat through heat exchange with a part of the telematics module (1000) or the frame (9) of the vehicle. The heating surface (S2) of the heat dissipation module (1600) may be configured to dissipate heat through heat exchange with a part of the case formed by the lower cover (1020) and the upper cover (1010) or the frame (9) of the vehicle.
[0081] The telematics module (1000) may be configured to include a lower cover (1020), an upper cover (1010), a PCB (1200), a first heat generating module (1300) corresponding to an NAD module, and a second heat generating module (1400) corresponding to a V2X module. The telematics module (1000) of FIG. 5 may be configured to further include a processor (1350). The processor (1350) may be implemented as an MCU (Micro Controller Unit) that controls the operation of the vehicle. The lower cover (1020) and the upper cover (1010) may be referred to as a first cover and a second cover, respectively. The first heat generating module (1300) and the second heat generating module (1400) may be implemented as PCBs. The first heat generating module (1300) and the second heat generating module (1400) may be referred to as a first PCB and a second PCB.
[0082] The lower cover (1020) may be formed as a heat sink structure so that heat generated within the telematics module (1000) can be discharged to the outside through the metal frame (9). The lower cover (1020) may be configured to include a bottom surface coupled to the metal frame (9) of the vehicle, and a first protruding surface (PS1) and a second protruding surface (PS2) protruding from the bottom surface. Meanwhile, the lower cover (1020) may be configured to include a bottom surface coupled to the metal frame (9) of the vehicle, a first protruding surface (PS1) and a second protruding surface (PS2) protruding from the bottom surface, and a third protruding surface (PS3) between the first protruding surface (PS1) and the second protruding surface (PS2).
[0083] Since the heat generated from the first heating module (1300) is greater than the heat generated from other modules, the first protruding surface (PS1) may be formed with a structure in which the interior is filled with a metal structure. The first protruding surface (PS1) may be formed integrally with a lower cover (1020) made of a metal material. The second protruding surface (PS2) and the third protruding surface (PS3) may be formed with a structure in which the interior is hollow. One end and the other end of the second protruding surface (PS2) may be formed with a structure in which the lower cover (1020) is connected. One end and the other end of the third protruding surface (PS3) may be formed with a structure in which the lower cover (1020) is connected.
[0084] Fig. 6 illustrates the structure of the lower cover of Fig. 4 or Fig. 5. Referring to Figs. 4 to 6, a heat dissipation module (1600) may be placed between the NAD module (1300) and the first protruding surface (PS1) of the lower cover (1020). The first protruding surface (PS1) may be formed in the first region (1020R1) of the lower cover (1020), and the heat dissipation module (1600) may be placed so as to be in contact with the first protruding surface (PS1).
[0085] As the heat dissipation module (1600) is applied, the second thickness of the second region (1020R2) of the lower cover (1020) may be formed to be smaller than the first thickness of the first region (1020R1) in order to minimize the heat generated in the heat dissipation module (1600) from being transferred to the MCU and V2X components. The second region (1020R2) of the lower cover (1020) may be referred to as a reduced region with a reduced thickness. As the thickness of the second region (1020R2) of the lower cover (1020) is reduced, the heat generated in the heat dissipation module (1600) from being transferred to the surroundings can be minimized, and the product weight can also be reduced.

The first heat wire (1610), the second heat wire (1620), and the third heat wire (1630) may be connected to the heat dissipation module (1600) through the internal lines (1021, 1022, 1023) of the lower cover (1020).
[0126] Referring to FIG. 14, a cooling device having a structure in which a heat sink structure is connected may further include a plurality of spacers (1500s). The spacers (1500s) may be arranged to secure specific points (first points) of a first thermal wire (1610) connected to a first heat dissipation module (1710) and a lower cover (1020). The spacers (1500s) may be arranged to secure specific points (second points) of a second thermal wire (1620) connected to a second heat dissipation module (1720) and a lower cover (1020). The spacers (1500s) may be arranged to secure specific points (third points) of a third thermal wire (1630) connected to a third heat dissipation module (1730) and a lower cover (1020).
[0127] A plurality of spacers (1500s) may be arranged to connect different points of the lower cover (1020) and specific points of the first heat wire (1610), the second heat wire (1620), and the third heat wire (1630). In this regard, the plurality of spacers (1500s) may be configured to include a first spacer (1510s), a second spacer (1520s), and a third spacer (1530s). A plurality of first spacers (1510s) may be arranged to secure specific points (first points) of the first heat wire (1610) connected to the first surface (S1) of the first heat dissipation module (1710) and the lower cover (1020). The second spacers (1520s) may be arranged in multiple pieces to secure specific points (second points) of the second heat wire (1620) connected to the first surface (S1) of the second heat dissipation module (1720) and the lower cover (1020). The third spacers (1530s) may be arranged in multiple pieces to secure specific points (third points) of the third heat wire (1630) connected to the first surface (S1) of the third heat dissipation module (1730) and the lower cover (1020).
[0128] Meanwhile, in relation to the cooling device of the vehicle according to the present specification, the telematics module may be configured to measure the internal temperature and the first temperature of the memory to operate in one of a plurality of operating modes in the boot mode. In this regard, Fig. 15 illustrates a flowchart of a control method for a telematics module entering the boot mode in relation to the cooling device of the vehicle. Fig. 16 illustrates a flowchart of a control method for controlling a telematics module entering the boot mode in relation to the cooling device of the vehicle to operate in one of a plurality of operating modes.
[0129] Referring to FIGS. 4 to 16, a control method performed in a first heating module (1300) of a telematics module mounted on a vehicle according to the present specification and a telematics module (1000) performing the same will be described in detail. The first heating module (1300) may be composed of an NAD module including a modem (1310), a memory (1320) disposed adjacent to the modem (1310), and an RF transceiver (1330) operably coupled to the modem (1310). Hereinafter, the first heating module (1300) including the modem (1310), the memory (1320), and the RF transceiver (1330) will be referred to as an NAD module (1300). Meanwhile, temperature control based on the temperature of the aforementioned electronic components may be performed by the NAD module (1300) or by another processor that controls heat generation.
[0130] The NAD module (1300) can determine a heat dissipation mode based on the internal temperature (Ta) of the telematics module (1000). In this regard, power is supplied to the NAD module (1300) (S10), and the first temperature (T1) of the memory (1320) and the NAD module (1300) can measure the internal temperature (Ta) (S20). In addition, the NAD module (1300) can determine whether the internal temperature (Ta) or the first temperature (T1) of the memory (1320) is higher than or equal to a first threshold temperature (Tset_a, Tset1) (S30).
[0131] The NAD module (1300) can control (S40) the heat dissipation module (1600) to operate in a first heat dissipation mode in which the heat dissipation module operates at maximum heat dissipation capability when the internal temperature (Ta) is higher than the first threshold temperature (Tset_a). In addition, the NAD module (1300) can control (S40) the heat dissipation module (1600) to operate in a first heat dissipation mode in which the heat dissipation module operates at maximum heat dissipation capability when the first temperature (T1) of the memory (1320) is higher than the first threshold temperature (Tset1). In this regard, the first threshold temperature (Tset_a) and the first threshold temperature (Tset1) can be set to the same temperature, for example, 85 degrees. In the first heat dissipation mode, a first voltage value can be applied to the heat dissipation module (1600). In order to operate in the first heat dissipation mode, a first voltage value of 10 V may be applied to the heat dissipation module (1600), and a first current value of 1.3 A may be measured. Meanwhile, in the first heat dissipation mode, a first voltage value may be applied to the heat dissipation module (1600), and heat of the NAD module (1300), which is the first heat generating module, may be released at a first speed through the first heat wire (1610).
[0132] The NAD module (1300) starts a boot mode (S50) in which the operation of the telematics module (1000) begins when the internal temperature (Ta) is lower than the first threshold temperature (Tset_a). In addition, the NAD module (1300) starts a boot mode (S50) in which the operation of the telematics module (1000) begins when the first temperature (T1) of the memory (1320) is lower than the first threshold temperature (Tset1).
[0133] If the internal temperature (Ta) is higher than the first threshold temperature (Tset_a) or the first temperature (T1) of the memory (1320) is higher than the first threshold temperature (Tset1), a process of controlling operation in the first heat dissipation mode (S40) is performed. Thereafter, the first temperature (T1) of the memory (1320) and the NAD module (1300) can measure the internal temperature (Ta) again (S20b). Thereafter, it can be determined (S30b) whether the internal temperature (Ta) and the first temperature (T1) of the memory (1320) are lower than the first threshold temperature (Tset_a, Tset1).
[0134] When the boot mode (S50) starts, the NAD module (1300) can check the operation mode (call mode) (S100) and perform one of the plurality of operation modes. In this regard, the NAD module (1300) can control to perform one of the first operation mode, the second operation mode, and the third operation mode among the plurality of operation modes based on the boot signal and the operation mode. The first operation mode may be an emergency call mode, the second operation mode may be a remote start mode, and the third operation mode may be a trip mode.
[0135] As described above, the telematics module mounted on a vehicle according to the present specification may be configured to operate in one of a plurality of operating modes based on the temperatures of a plurality of components and the internal temperature. In this regard, FIGS. 17 to 19 illustrate flowcharts of a method for controlling a telematics module according to first to third operating modes in relation to a cooling device of a vehicle. FIG. 17 illustrates a flowchart of a method for controlling a telematics module operating in a first operating mode, which is an emergency call mode. FIG. 18 illustrates a flowchart of a method for controlling a telematics module operating in a second operating mode, which is a remote start mode. FIG. 19 illustrates a flowchart of a method for controlling a telematics module operating in a third operating mode, which is a trip mode.
[0136] Referring to FIGS. 4 to 19, a control method performed in an NAD module (1300) of a telematics module mounted on a vehicle according to the present specification and a telematics module (1000) performing the same will be described in detail. Depending on the operation mode, the NAD module (1300) can perform a first operation mode (S200). Depending on the operation mode, the NAD module (1300) can perform a second operation mode (S300). Depending on the operation mode, the NAD module (1300) can perform a third operation mode (S400). In each operating mode, a first temperature (T1) of the memory (1310), a second temperature (T2) of the RF transceiver (1320), a third temperature (T3) of the electronic component (1410) of the V2X module (1400), and an internal temperature (Ta) of the telematics module (1000) can be measured (S210, S310, S410).
[0137] Based on the boot signal, a first heat dissipation mode may be performed in which the heat dissipation module (1600) is driven at a first voltage value in each operation mode. Meanwhile, in the first heat dissipation mode, a first voltage value may be applied to the heat dissipation module (1600) so that the flow rate of the refrigerant discharged through the input pipe (1610) may be discharged at a first speed. Based on the call command, a second heat dissipation mode may be performed in which the heat dissipation module (1600) is driven by changing the second voltage value lower than the first voltage value in each operation mode. Meanwhile, in the second heat dissipation mode, a second voltage value may be applied to the heat dissipation module (1600) so that the heat of the NAD module (1300), which is the first heat generating module, may be discharged at a second speed lower than the first speed of the first heat dissipation mode through the first heat wire (1610).
[0138] The first operation mode is e-call mode and the operation condition is a mode that operates in an emergency situation. The first operation mode is a mode that can maintain normal operation for 300 seconds without failure in an environment where the internal temperature (Ta) of the telematics module (1000) is 105 degrees. In the first operation mode, the first temperature (T1) of the memory (1310) is compared with the first and second threshold temperatures (Tset1, Tset2) (S220a, S230a, 240a), and the heat dissipation operation can be stopped (S220), or the first heat dissipation mode (S230) or the second heat dissipation mode (S240) can be performed.
[0139] Even if the heat dissipation module (1600) does not operate at 85 degrees, which is 20 degrees lower than the temperature specification of 105 degrees for the memory (1310) implemented with MCP LPDDR4, the memory (1310) can operate for about 5 minutes. Accordingly, the first critical temperature (Tset1) can be set to 85 degrees. Although there may be differences depending on the actual vehicle situation, since the memory (1310) can operate for about 5 minutes even if the heat dissipation module (1600) does not operate, the operating condition of the first operating mode, which is the e-call mode, can be satisfied.
[0140] In order to maintain component operation and temperature reliability with a temperature margin of 10 degrees or more than 105 degrees, which is the temperature specification of the memory (1310) implemented with MCP LPDDR4, the second critical temperature (Tset2) may be set to 95 degrees. In the first operation mode, which is the e-call mode, the third critical temperature (Tset_a3) of the internal temperature (Ta) of the telematics module (1000) may be set to 105 degrees. The NAD module (1300) may measure (S210) the first temperature (T1) of the memory (1310) and the internal temperature (Ta) of the telematics module (1000) in the first operation mode.
[0141] The NAD module (1300) can control the heat dissipation operation of the heat dissipation module (1600) to be stopped (S220) when the first temperature (T1) of the memory (1310) measured in the first operation mode is lower than or equal to the first threshold temperature (Tset1) (S220a). In this regard, the voltage of the first region (1600R1) of the heat dissipation module (1600) connected to the connection parts coupled to the first sub-region (1300R1) where the memory (1310) is arranged can be cut off. In this regard, the plurality of connection parts can include the first connection part (1611) to the sixth connection part (1616) as shown in Fig. 10(a). The connection parts coupled to the first sub-region (1300R1) can be set to three or more, including the first connection part (1611) to the third connection part (1613), in consideration of the amount of heat generated. The plurality of connecting parts may include the first connecting part (1611) to the eighth connecting part (1618) as shown in Fig. 10(b). The connecting parts coupled to the first sub-region (1300R1) may be set to four or more, including the first connecting part (1611) to the fourth connecting part (1614), taking into account the amount of heat generated.
[0142] The NAD module (1300) can be controlled to operate in a second heat dissipation mode (S230) when the first temperature (T1) of the memory (1310) is greater than the first threshold temperature (Tset1) and less than or equal to the second threshold temperature (Tset2) (S230a). The NAD module (1300) can drive the heat dissipation module (1600) with a second voltage value (e.g., 7 V) and a second current value (e.g., 1.0 A) to operate in the second heat dissipation mode (S230). In this regard, the NAD module (1300) can drive the first region (1600R1) of the heat dissipation module (1600) with the second voltage value and the second current value. The NAD module (1300) can drive a first region (1600R1) of a heat dissipation module (1600) connected to connection parts coupled to a first sub-region (1300R1) with a second voltage value and a second current value.
[0143] The NAD module (1300) can be controlled to operate in a first heat dissipation mode (S240) when the first temperature (T1) of the memory (1310) is greater than the second threshold temperature (Tset2) or the internal temperature (Ta) of the telematics module (1000) is greater than the third threshold temperature (Tset_a3) (S240a). The NAD module (1300) can drive the heat dissipation module (1600) with a first voltage value (e.g., 10 V) and a first current value (e.g., 1.3 A) to operate in the first heat dissipation mode (S240). In this regard, the NAD module (1300) can drive the first region (1600R1) of the heat dissipation module (1600) with the first voltage value and the first current value. The NAD module (1300) can drive a first region (1600R1) of a heat dissipation module (1600) connected to connection parts coupled to a first sub-region (1300R1) with a first voltage value and a first current value.
[0144] Thereafter, in each heat dissipation mode, the NAD module (1300) can re-measure (S210b) the first temperature (T1) of the memory (1310) and the internal temperature (Ta) of the telematics module (1000). Thereafter, the process of comparing (S220a, S230a, S240a) the first temperature (T1) of the memory (1310) with the first and second threshold temperatures (Tset1, Tset2) can be repeated.
[0145] The second operation mode is a remote start mode and is a mode in which normal operation can be maintained for 60 seconds without failure in an environment in which the internal temperature (Ta) of the telematics module (1000) is 105 degrees. In the second operation mode, the first temperature (T1) of the memory (1310) or the second temperature (T2) of the RF transceiver (1320) is compared with the first and second threshold temperatures (Tset1, Tset2) (S220a, S230a, 240a), and the heat dissipation operation can be stopped (S320) or the first heat dissipation mode (S330) or the second heat dissipation mode (S340) can be performed. The NAD module (1300) can measure (S310) the first temperature (T1) of the memory (1310), the second temperature (T2) of the RF transceiver (1320), and the internal temperature (Ta) of the telematics module (1000) in the second operation mode.
[0146] The NAD module (1300) can control the heat dissipation operation of the heat dissipation module (1600) to be stopped (S320) if the first temperature (T1) of the memory (1310) or the second temperature (T2) of the RF transceiver (1320) measured in the second operation mode is lower than or equal to the first threshold temperature (Tset1) (S320a). In this regard, if the first temperature (T1) of the memory (1310) is lower than or equal to the first threshold temperature (Tset1), the voltage of the first region (1600R1) of the heat dissipation module (1600) connected to the connecting parts coupled to the first sub-region (1300R1) in which the memory (1310) is arranged can be cut off. Meanwhile, if the second temperature (T2) of the RF transceiver (1320) is lower than or equal to the first threshold temperature (Tset1), the voltage of the second region (1600R2) of the heat dissipation module (1600) connected to the connecting parts coupled to the second sub-region (1300R2) where the RF transceiver (1320) is arranged can be blocked.
[0147] In this regard, the plurality of connecting parts may include the first connecting part (1611) to the sixth connecting part (1616) as shown in Fig. 10(a). The connecting parts coupled to the first sub-region (1300R1) may be set to three or more, including the first connecting part (1611) to the third connecting part (1613), in consideration of the amount of heat generated. The connecting parts coupled to the second sub-region (1300R2) may be set to three or less, excluding the connecting parts coupled to the first sub-region (1300R1). The plurality of connecting parts may include the first connecting part (1611) to the eighth connecting part (1618) as shown in Fig. 10(b). The connecting parts coupled to the first sub-region (1300R1) may be set to four or more, including the first connecting part (1611) to the fourth connecting part (1614), in consideration of the amount of heat generated. The number of connecting parts coupled to the second sub-area (1300R2) may be set to four or less, excluding the connecting parts coupled to the first sub-area (1300R1).
[0148] The NAD module (1300) can be controlled to operate in a second heat dissipation mode (S330) if the first temperature (T1) of the memory (1310) or the second temperature (T2) of the RF transceiver (1320) is greater than the first threshold temperature (Tset1) and less than or equal to the second threshold temperature (Tset2) (S330a). The NAD module (1300) can drive the heat dissipation module (1600) with a second voltage value (e.g., 7 V) and a second current value (e.g., 1.0 A) to operate in the second heat dissipation mode (S330). In this regard, if the first temperature (T1) of the memory (1310) is less than or equal to the second threshold temperature (Tset2), the NAD module (1300) can drive the first region (1600R1) of the heat dissipation module (1600) with the second voltage value and the second current value. The NAD module (1300) can drive the first region (1600R1) of the heat dissipation module (1600) connected to the connecting portions coupled to the first sub-region (1300R1) with the second voltage value and the second current value. When the second temperature (T2) of the RF transceiver (1320) is lower than or equal to the second threshold temperature (Tset2), the NAD module (1300) can drive the second region (1600R2) of the heat dissipation module (1600) with the second voltage value and the second current value. The NAD module (1300) can drive the second region (1600R2) of the heat dissipation module (1600) connected to the connecting portions coupled to the second sub-region (1300R2) with the second voltage value and the second current value.
[0149] The NAD module (1300) can be controlled to operate in a first heat dissipation mode (S340) when the first temperature (T1) of the memory (1310) or the second temperature (T2) of the RF transceiver (1320) is greater than the second threshold temperature (Tset2) or the internal temperature (Ta) of the telematics module (1000) is greater than the third threshold temperature (Tset_a3) (S340a). The NAD module (1300) can drive the heat dissipation module (1600) with a first voltage value (e.g., 10 V) and a first current value (e.g., 1.3 A) to operate in the first heat dissipation mode (S340). In this regard, if the first temperature (T1) of the memory (1310) is greater than the second threshold temperature (Tset2), the NAD module (1300) can drive the first region (1600R1) of the heat dissipation module (1600) with the first voltage value and the first current value. The NAD module (1300) can drive the first region (1600R1) of the heat dissipation module (1600) connected to the connecting parts coupled to the first sub-region (1300R1) with the first voltage value and the first current value. If the second temperature (T2) of the RF transceiver (1320) is greater than the second threshold temperature (Tset2), the NAD module (1300) can drive the second region (1600R2) of the heat dissipation module (1600) with the first voltage value and the first current value. The NAD module (1300) can drive a second region (1600R2) of a heat dissipation module (1600) connected to connection parts coupled to a second sub-region (1300R2) with a first voltage value and a first current value.
[0150] Thereafter, in each heat dissipation mode, the NAD module (1300) can re-measure (S310b) the first temperature (T1) of the memory (1310), the second temperature (T2) of the RF transceiver (1320), and the internal temperature (Ta) of the telematics module (1000). Thereafter, the process of comparing (S320a, S330a, S340a) the first temperature (T1) of the memory (1310) or the second temperature (T2) of the RF transceiver (1320) with the first and second threshold temperatures (Tset1, Tset2) can be repeated.
[0151] The third operation mode is a trip mode, and is a mode in which normal operation can be maintained for 1500 seconds without failure in an environment in which the internal temperature (Ta) of the telematics module (1000) decreases from 105 degrees to 75 degrees. In the third operation mode, the first temperature (T1) of the memory (1310) or the second temperature (T2) of the RF transceiver (1320) is compared with the first and second threshold temperatures (Tset1, Tset2), and the third temperature (T3) of the electronic component (1410) is compared with the third threshold temperature (Tset3) (S220a, S230a, 240a), whereby the heat dissipation operation can be stopped (S320), or the first heat dissipation mode (S330) or the second heat dissipation mode (S340) can be performed. The NAD module (1300) can measure (S410) the first temperature (T1) of the memory (1310), the second temperature (T2) of the RF transceiver (1320), the third temperature (T3) of the electronic component (1410) of the V2X module (1400), and the internal temperature (Ta) of the telematics module (1000) in the third operation mode.
[0152] The NAD module (1300) determines (S420a) whether the first temperature (T1) of the memory (1310) or the second temperature (T2) of the RF transceiver (1320) measured in the third operation mode is equal to or lower than the first threshold temperature (Tset1) and whether the third temperature (T3) of the electronic component (1410) of the V2X module (1400) is equal to or lower than the second threshold temperature (Tset2). Accordingly, the NAD module (1300) can control the heat dissipation operation of the heat dissipation module (1600) to be stopped (S420). In this regard, if the first temperature (T1) of the memory (1310) is equal to or lower than the first threshold temperature (Tset1), the voltage of the first region (1600R1) of the heat dissipation module (1600) connected to the connecting parts coupled to the first sub-region (1300R1) in which the memory (1310) is arranged can be cut off. Meanwhile, if the second temperature (T2) of the RF transceiver (1320) is lower than or equal to the first threshold temperature (Tset1), the voltage of the second region (1600R2) of the heat dissipation module (1600) connected to the connecting parts coupled to the second sub-region (1300R2) where the RF transceiver (1320) is arranged can be blocked.
[0153] The NAD module (1300) determines (S430a) whether the first temperature (T1) of the memory (1310) or the second temperature (T2) of the RF transceiver (1320) is greater than the first threshold temperature (Tset1) and less than or equal to the second threshold temperature (Tset2), and whether the third temperature (T3) of the electronic component (1410) is greater than the second threshold temperature (Tset2) and less than or equal to the third threshold temperature (Tset3). Accordingly, the NAD module (1300) can control the heat dissipation module (1600) to operate in the second heat dissipation mode (S430). The NAD module (1300) can drive the heat dissipation module (1600) with a second voltage value (e.g., 7 V) and a second current value (e.g., 1.0 A) to operate in the second heat dissipation mode (S430). In this regard, if the first temperature (T1) of the memory (1310) is equal to or lower than the second threshold temperature (Tset2), the NAD module (1300) can drive the first region (1600R1) of the heat dissipation module (1600) with the second voltage value and the second current value. The NAD module (1300) can drive the first region (1600R1) of the heat dissipation module (1600) connected to the connecting parts coupled to the first sub-region (1300R1) with the second voltage value and the second current value. If the second temperature (T2) of the RF transceiver (1320) is equal to or lower than the second threshold temperature (Tset2), the NAD module (1300) can drive the second region (1600R2) of the heat dissipation module (1600) with the second voltage value and the second current value. The NAD module (1300) can drive a second region (1600R2) of a heat dissipation module (1600) connected to connection parts coupled to a second sub-region (1300R2) with a second voltage value and a second current value.
[0154] The NAD module (1300) determines (S440a) whether the first temperature (T1) of the memory (1310) or the second temperature (T2) of the RF transceiver (1320) is greater than the second threshold temperature (Tset2) and less than or equal to the third threshold temperature (Tset3), and whether the third temperature (T3) of the electronic component (1410) is greater than the third threshold temperature (Tset3). In addition, the NAD module (1300) determines (S440a) whether the internal temperature (Ta) of the telematics module (1000) is greater than the third threshold temperature (Tset_a3). Accordingly, the NAD module (1300) can control the heat dissipation module (1600) to operate in the first heat dissipation mode (S440). The NAD module (1300) can drive the heat dissipation module (1600) with a first voltage value (e.g., 10 V) and a first current value (e.g., 1.3 A) to operate in a first heat dissipation mode (S440). In this regard, when the first temperature (T1) of the memory (1310) is greater than the second threshold temperature (Tset2), the NAD module (1300) can drive the first region (1600R1) of the heat dissipation module (1600) with the first voltage value and the first current value.
