[0051] The embodiment provides a kind of vehicle heat management unit, with higher integration, save automobile installation space;Optimize wire harness layout, reduce wire harness entanglement, abrasion and other problems, save cost.
[0052] As Figures 1-3 As shown in the figure, the vehicle heat management unit mainly includes frame body 10, electric control box 20, fan 11, water pump 12, compressor 16 and PTC heater 13. Among them, electric control box 20 is arranged on frame body 10. DCDC module 21, compressor controller module 22 and PTC power distribution relay module 23 are arranged in electric control box 20. Fan 11 is arranged on the side wall of frame body 10, water pump 12 is arranged on the top of frame body 10, and water pump 12 and fan 11 are electrically connected with DCDC module 21. Compressor 16 is arranged on the top of frame body 10, and compressor 16 is electrically connected with compressor controller module 22. PTC heater 13 is arranged on the top of frame body 10, and PTC heater 13 is electrically connected with PTC power distribution relay module 23.
[0053] Based on the above design, in the embodiment, by providing the electric control box 20 on the rack body 10, and then embedding the DCDC module 21, the compressor controller module 22 and the PTC power distribution relay module 23 in the electric control box 20, the DCDC module 21, the compressor controller module 22 and the PTC power distribution relay module 23 form an independent component, avoiding the need to separately layout the above three components in the prior art, improving the integration level and saving installation space. At the same time, during assembly, only the electric control box 20 needs to be fixed and installed on the rack body 10, avoiding the cumbersome steps of installing three separate components in the prior art, improving assembly efficiency. In addition, since the DCDC module 21, the compressor controller module 22 and the PTC power distribution relay module 23 are all embedded and integrated in the electric control box 20, the wire harness length can be shortened as much as possible, the layout of the wire harness is optimized, the problems such as winding and wear of the wire harness are reduced, and the safety is improved. At the same time, it also reduces the difficulty of technicians to find faults and maintain in the later period, saves maintenance cost and time cost.
[0054] The DCDC module 21 in the embodiment is a direct current-direct current converter, which mainly converts high-voltage direct current of a vehicle power battery into low-voltage direct current suitable for vehicle-mounted low-voltage equipment (i.e. the fan 11 and the water pump 12 in the embodiment) to provide stable power support for the fan 11 and the water pump 12. For example, the DCDC module 21 converts the high-voltage power output (such as 400V) into low-voltage power (such as 12V / 24V) to meet the needs of the fan 11 and the water pump 12, avoiding the safety risks of directly using high-voltage power by the fan 11 and the water pump 12.
[0055] The compressor controller module 22 can be set as a compressor control circuit board, which can quickly start the compressor 16 in a high-temperature environment, reduce the battery temperature through refrigerant circulation, and prevent thermal runaway.
[0056] The PTC power distribution relay module 23 is used to control the on-off of the PTC heater 13 circuit, which can quickly turn on or turn off the power supply circuit of the PTC heater 13 to realize heating start-stop control. The PTC power distribution relay module 23 is integrated in the electric control box 20, which can reduce the length of the wire harness and reduce the failure rate of the connection point.
[0057] The rack body 10 in the embodiment is made of a plate material, which improves the reliability and mechanical strength of the vehicle heat management unit.
[0058] As Figures 4-6As shown, the electric control box 20 in the embodiment includes a shell 24, the first connecting plate 14 is arranged on the frame body 10, the bottom of the shell 24 is formed with a second connecting plate 25, the first connecting plate 14 is arranged with a first mounting hole, the second connecting plate 25 is arranged with a second mounting hole, and the vehicle thermal management unit further includes a fixing member, the fixing member is arranged in the first mounting hole and the second mounting hole, so that the electric control box 20 is installed on the frame body 10.
[0059] Through the arrangement of the first connecting plate 14, the second connecting plate 25 and the fixing member, the electric control box 20 can be installed on the frame body 10, and the electric control box 20 can be easily disassembled and maintained later. Optionally, the fixing member in the embodiment can be a screw or a bolt. The first mounting hole and the second mounting hole are arranged opposite to each other.
[0060] In some optional embodiments, the electric control box 20 includes a shell 24 and mounting ears, the mounting ears are arranged in two, and the two mounting ears are respectively located on opposite sides of the shell 24 and are integrally formed with the shell 24, so that the machining process is reduced, the assembly efficiency is improved, and the mechanical strength of the shell 24 is improved. The first mounting hole is arranged on the mounting ear, the second mounting hole is arranged on the frame body 10, and the vehicle thermal management unit further includes a fixing member, the fixing member is arranged in the first mounting hole and the second mounting hole, so that the electric control box 20 is installed on the frame body 10. The two oppositely arranged mounting ears can improve the stress of the shell 24 and improve the stability and reliability.
[0061] As shown in the embodiment, the shell 24 has a receiving cavity 241, the DCDC module 21, the compressor controller module 22 and the PTC power distribution relay module 23 are arranged in the receiving cavity 241. Figures 4-6 The electric control box 20 includes a power bus, one end of the power bus is electrically connected with the power battery of the automobile, the other end of the power bus is divided into a first branch, a second branch and a third branch, the first branch is electrically connected with the DCDC module 21, the second branch is electrically connected with the compressor controller module 22, and the third branch is electrically connected with the PTC power distribution relay.
[0062] In this way, the current in the power battery of the automobile can be divided into three paths after passing through the power bus: one path flows into the DCDC module 21 along the first branch to supply power to the DCDC module 21, another path flows into the compressor controller module 22 along the second branch to supply power to the compressor controller module 22, and the last path flows into the PTC power distribution relay along the third branch to supply power to the PTC power distribution relay.
[0063] Furthermore, the vehicle thermal management unit in this embodiment also includes a first cable, a second cable, a third cable, and a fourth cable. The housing 24 is provided with a first through hole for the first cable to pass through, a second through hole for the second cable to pass through, a third through hole for the third cable to pass through, and a fourth through hole for the fourth cable to pass through.
[0064] One end of the first cable is electrically connected to the DC-DC module 21, and the other end passes through the first through-hole and is electrically connected to the water pump 12. One end of the second cable is electrically connected to the DC-DC module 21, and the other end passes through the second through-hole and is electrically connected to the fan 11. In other words, in this embodiment, the DC-DC module 21 supplies power to the water pump 12 and the fan 11 respectively through the first and second cables, so as to convert the high-voltage DC power of the vehicle's power battery into low-voltage DC power. It is understood that the fan 11 and the water pump 12 are connected in parallel and do not affect each other.
[0065] One end of the third cable is electrically connected to the compressor controller module 22, and the other end passes through the third through hole and is electrically connected to the compressor 16, so that the compressor controller module 22 can quickly start the compressor 16 in a high-temperature environment, reduce the battery temperature through refrigerant circulation, and prevent thermal runaway.
[0066] One end of the fourth cable is electrically connected to the PTC power distribution relay module 23, and the other end passes through the fourth through hole and is electrically connected to the PTC heater 13. This enables the PTC power distribution relay module 23 to control the on / off state of the PTC heater 13 circuit, and to quickly connect or disconnect the power supply circuit of the PTC heater 13, thereby realizing heating start / stop control.
[0067] like Figure 6 As shown, in this embodiment, the housing 24 is also provided with multiple sets of heat dissipation fins 26, and the multiple sets of heat dissipation fins 26 extend in a direction away from the receiving chamber 241. In other words, the heat dissipation fins 26 are located outside the receiving chamber 241. The arrangement of the heat dissipation fins 26 can improve the heat dissipation efficiency and heat dissipation performance of the electrical control box 20.
[0068] like Figures 1-3 As shown, in this embodiment, the vehicle thermal management unit further includes a heat exchanger 15, which has a refrigerant inlet and a refrigerant outlet connected to each other, as well as a water inlet and a water outlet connected to each other. The refrigerant inlet and refrigerant outlet form a refrigerant path, and the water inlet and water outlet are connected to each other to form a water path, allowing the refrigerant in the refrigerant path to exchange heat with the water in the water path. Specifically, the water pump 12 is connected to the water inlet, and the water outlet is connected to the PTC heater 13. The vehicle thermal management unit also includes a condenser, whose outlet is connected to the refrigerant inlet of the heat exchanger 15, and the refrigerant outlet is connected to the suction port of the compressor 16.
[0069] In this way, the refrigerant flowing out of the outlet of the condenser core flows into the refrigerant inlet of the heat exchanger 15, the refrigerant outlet of the heat exchanger 15, and then the suction port of the compressor 16 in sequence. The water in the water circuit flows out of the outlet of the water pump 12, flows into the water inlet of the heat exchanger 15, the water outlet of the heat exchanger 15, and then flows into the PTC heater 13 in sequence. In this process, the refrigerant in the refrigerant circuit and the water in the water circuit can exchange heat in the heat exchanger 15.
[0070] Exemplarily, the heat exchanger 15 in the embodiment is a plate heat exchanger.
[0071] Exemplarily, the fan 11 in the embodiment can be provided in plurality, and the plurality of fans 11 are arranged at equal intervals. In this way, the heat dissipation performance of the vehicle thermal management unit is improved, and the safety performance is improved.
