Description

Technical Field

[0001] The present invention relates to the technical field of wiring harnesses for new energy vehicles, and in particular to a temperature control and shielding device for aluminum bus wiring harnesses for new energy vehicles. Background Art

[0002] In the field of new energy vehicles, aluminum wiring harnesses are key power transmission components, and their performance directly affects the safety and reliability of the vehicle. However, in the use of aluminum wiring harnesses, the shielding of electromagnetic interference (EMI) has always been a prominent technical challenge. Existing shielding technologies mainly include shielding nets and copper foil winding methods. Although these methods can provide shielding effects to a certain extent, they have obvious shortcomings. The shielding net is complicated to install, expensive, and requires special high-voltage connectors to use, which increases the complexity and cost of manufacturing. The copper foil winding method has poor bending resistance and is easily damaged in the application environment where the aluminum wiring harness is frequently bent, affecting the shielding effectiveness and the life of the harness.

[0003] In addition, the current shielding technology also brings certain difficulties in installation efficiency and subsequent maintenance. For example, the shielding net and copper foil winding methods require high-precision operations, which not only increases production time, but also increases the skill requirements for production personnel. At the same time, once the shielding layer is damaged, the replacement process is complicated and the maintenance cost is high. Moreover, the current aluminum wiring harness can only dissipate heat passively, resulting in very limited heat dissipation performance, which can easily lead to serious local heat accumulation. Summary of the invention

[0006] The surface of the outer sheath is located at two sides of the external connection seat and has an external guide tube connected to the external guide chamber and an external return tube connected to the external return chamber.

[0007] An external metal heat-conducting cover is arranged on the inner side of the outer sheath at the position of the external flow guide chamber and the external return chamber.

[0008] Built-in metal heat-conducting covers are provided on the inner sides of the built-in flow guide chamber and the built-in reflux chamber.

[0010] The electrically controlled flow guiding mechanism comprises a driving motor fixedly mounted on the inner top surface of the external connecting seat and a centrifugal driving blade axially fixed on the output end of the lower end of the driving motor.

[0011] A lateral connecting pipe with an integrated structure for connecting the built-in flow guiding chamber and the built-in return chamber is fixedly mounted on the outer side surface of the insulating layer.

They can resist certain external forces and damage to cables by rats, termites, etc. They are not easily damaged and can improve the flame retardant properties of cables. (3) The installation process of the aluminum strip is simple and does not require particularly precise operation. It only requires adding a set of interlocking armoring equipment to the production equipment, which reduces the difficulty and cost of production and maintenance; (4) An external guide chamber and an external return chamber are respectively provided on both sides of the outer sheath, and an internal guide chamber connected to the external guide chamber and an internal return chamber connected to the external return chamber are respectively provided on the inner walls on both sides of the insulating layer, and an electrically controlled guide mechanism is used to circulate air inside, thereby greatly improving the heat dissipation performance of the wiring harness; (5) The external connection seat adopts a split structure design, which is convenient for later assembly and reduces the difficulty of later maintenance; (6) By adopting a side-fitting structural design, the heat dissipation performance can be greatly improved without affecting the bending layout; (7) The lateral protection and durability of the wiring harness can be improved by using external metal thermal conductive covers and internal metal thermal conductive covers.
