All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment 1:

[0026] As Figures 1 to 4 shown, the present embodiment provides a multi-high-voltage fan wiring control box, which includes a housing 101 and a cover plate 102 installed on the housing 101. A cavity 100 is provided inside the housing 101. At least one group of high-voltage input ports and several high-voltage output power distribution ports are provided on the housing 101. Several high-voltage connection copper bars are provided in the cavity.

The integrated temperature controller 107 is provided with several temperature input ends, several flow input ends and several fan control output ends. The integrated temperature controller 107 changes the signals of the fan control output ends according to the signals received by the temperature input ends and the flow input ends.

[0027] The multi-high-voltage fan wiring control box 107 integrates the power distribution and control of the high-voltage fan group by adding an integrated temperature controller, strengthening the control.

[0028] The above-mentioned integrated temperature controller 107 is further provided with a signal output end. The signal output end can output the signals obtained by the temperature input end and the flow input end to realize information interaction.

[0029] On the housing 101, a low-voltage wiring port 106 is provided beside the high-voltage input port. A low-voltage power line, a signal acquisition line, a control signal line and a CAN network information line are connected to the low-voltage wiring port 106.

The signal acquisition line is connected to the temperature input end and the flow input end. The control signal line is connected to the fan control output end. The CAN network information line is connected to the signal output end.

[0030] On the inner side wall beside the low-voltage wiring port 106 of the housing 101, a metal shielding plate 110 is provided. A receiving space 111 is formed between the metal shielding plate 110 and the housing 101. The integrated temperature controller 107 is installed in the receiving space 111. The metal shielding plate 110 can effectively isolate the electromagnetic interference brought by the high-voltage electrical components inside the housing 101 to the integrated temperature controller 107 and the low-voltage output signals.

[0031] In the above-mentioned high-voltage input ports, high-voltage output power distribution ports and low-voltage wiring ports 106, grounded shielding nets are provided. A metal shielding layer is provided outside the high-voltage cable 113. When the high-voltage cable 113 passes through the high-voltage input ports, high-voltage output power distribution ports and low-voltage wiring ports 106, the metal shielding layer is attached to the shielding net. The shielding net and the metal shielding layer are grounded to achieve the purpose of preventing electromagnetic interference.

[0032] The above-mentioned metal shielding layer includes 3 to 5 copper foil layers, and the width of the metal shielding layer is greater than the width of the shielding net.

[0033] The above-mentioned high-voltage input port is electrically connected to the high-voltage output power distribution port through a high-voltage cable 113 and a high-voltage connection copper busbar. Specifically, the several high-voltage output power distribution ports include several positive output ports 108a and several negative output ports 108b.

The high-voltage positive input port 105a is connected to the positive connection copper busbar 109a through a high-voltage cable 113. The several positive output ports 108a are grouped in pairs of two. Each group of positive output ports 108a is connected to a fuse 104 through a Y-shaped copper busbar 109c. The other end of the fuse 104 is connected to the positive connection copper busbar 109a. The high-voltage connection copper busbar adopts a positive and negative segmented and partitioned design. The high and low wire harnesses are routed to avoid cross contact, preventing electrical components from being damaged due to accidental high-voltage contact. At the same time, the high and low wire harnesses are arranged separately, reducing electromagnetic interference to low-voltage communication signals.

[0034] In this embodiment, the number of positive output ports 108a and negative output ports 108b is 6, the number of fuses 104 is 3, and the integrated temperature controller 107 is provided with 2 temperature input terminals, 2 flow input terminals, and 3 fan control output terminals.

[0036] A sealing strip 103 is provided between the housing 101 and the cover plate 102. The housing 101, the sealing strip 103, and the cover plate 102 are fixed together by several screws 112, effectively preventing water vapor from entering the cavity and causing electric leakage.

[0037] Embodiment Two:

[0038] As Figure 5 shown, the multi-high-voltage-fan wire splitting control box provided in this embodiment is similar to the multi-high-voltage-fan wire splitting control box described in Embodiment One. The difference lies in:

[0039] The above-mentioned integrated temperature controller 107 is installed on the cover plate 102 and is located outside the cavity. This enables the integrated temperature controller 107 to completely avoid the high-voltage area inside the housing, effectively preventing signal interference from high-voltage components to the integrated temperature controller 107.

[0040] Embodiment Three:

[0041] As Figure 6 shown, the radiator provided in this embodiment is a radiator, including a radiator body 8 and a multi-high-pressure-fan splitter control box 9. A heat dissipation waterway and several high-pressure fan groups 82 are provided in the radiator body 8, and each high-pressure fan group 82 is controlled by a high-pressure fan controller 81.

[0043] By improving the multi-high-pressure-fan splitter control box 9, the integrated temperature controller 107 is integrated inside. The multi-high-pressure-fan splitter control box 9 simultaneously realizes power distribution and control of the high-pressure fan groups 82, making the integration degree of the radiator higher and the electrical wiring more convenient.

[0044] The above-mentioned integrated temperature controller 107 is also provided with a signal output end, and the signal output end is electrically connected to the vehicle controller VCU. The integrated temperature controller 107 sends the temperature information, flow information of the heat dissipation waterway and the control information of the radiator fans to the vehicle controller VCU. The multi-high-pressure-fan splitter control box 9 sends data such as the water temperature, flow information of the waterway of the radiator body 8 and the operating state of the high-pressure fans to the vehicle controller VCU through the CAN bus, realizing temperature control integration and information interaction.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
