The invention discloses an insulating rubber layer forming method of a microchannel tube and the microchannel tube. The insulating rubber layer forming method of the microchannel tube includes the steps that a tube body of the microchannel tube is sealed, and is placed in an insulating rubber solution to be subjected to impregnation; the tube body of the microchannel tube subjected to impregnationis taken out, and a flowing insulating rubber solution is drained off; the tube body of the microchannel tube after being subjected to impregnation is baked; and the baked tube body of the microchannel tube is cooled till an insulating rubber layer on the outer wall of the tube body of the microchannel tube is cured and the microchannel tube is formed. According to the method, the outer layer ofthe tube body of the microchannel tube is made to form the insulating rubber layer, and a pasted insulating thin film is replaced; and due to the fact that the insulating rubber layer is directly formed on the outer surface of the tube body of the microchannel tube, the insulating rubber layer and the outer surface of the tube body of the microchannel tube are made to be in seamless attaching, nointerlayer gas exists, and the heat conduction performance of the microchannel tube is improved.
Description
technical field [0001] The invention relates to the field of new energy batteries, in particular to a method for forming an insulating adhesive layer of a microchannel tube and the microchannel tube. Background technique [0002] In the application of new energy battery modules, the battery module generates a lot of heat while working to provide power. The existing heat dissipation method is to cool the battery by circulating refrigerant in the microchannel tube. [0003] Most of the microchannel tubes currently on the market use a plastic insulating film pasted on the surface of the tube body, and the pasted plastic insulating film meets the insulation requirements of a voltage above 1280V. However, manual operation is used to paste the insulating film. When pasting, the insulating film is very easy to wrinkle, air is mixed in the folds, and there is a cross overlapping area at the butt joint of the insulating film, which leads to poor bonding effect and affects heat transf...
