Problems solved by technology
[0002] Due to technical reasons, the existing ultra-thin wall heat-conducting copper tubes have invalid sections of about 5mm-15mm after being flattened according to different diameters at both ends of the tube body. The ineffectiveness can only be reduced by increasing the shrinkage angle as much as possible. segment length to increase the effective utilization area of the heat pipe
However, reducing the length of the invalid section by increasing the shrinkage angle has disadvantages such as inconvenient operation, high sealing process requirements, and poor sealing effect.

Abstract
The invention discloses a cutting and sealing method for an ultrathin heat pipe and a device thereof. The method comprises the following steps that 1, a first positioning part and a second positioningpart which are spaced and oppositely arranged are provided, the opposite sides of the first positioning part and the second positioning part are each provided with a clamping face, and one clamping face is provided with a cutting portion protruding towards the other clamping face; 2, one end of the ultrathin heat pipe stretches to the position between the first positioning part and the second positioning part, and the position of the ultrathin heat pipe relative to the cutting portion is adjusted; 3, at least one of the first positioning part and the second positioning part is driven to moveto enable the two clamping faces to be close to each other till the cutting portion cuts off the end of the ultrathin heat pipe and the two clamping faces press the notch of the ultrathin heat pipe; and 4, the notch is sealed. According to the cutting and sealing method for the ultrathin heat pipe, the length of an invalid section can be effectively decreased, and the heat conduction area utilization rate of the ultrathin heat pipe is increased.
Description
technical field [0001] The invention belongs to the field of preparation of ultra-thin heat pipes, and more particularly relates to a cutting and sealing method for ultra-thin heat pipes and a cutting and sealing device for ultra-thin heat pipes. Background technique [0002] Due to technical reasons, the existing ultra-thin wall heat-conducting copper tubes have invalid sections of about 5mm-15mm after being flattened according to different diameters at both ends of the tube body. The ineffectiveness can only be reduced by increasing the shrinkage angle as much as possible. The section length is used to increase the effective utilization area of the heat pipe. However, reducing the length of the invalid section by increasing the shrinkage angle has disadvantages such as inconvenient operation, high sealing process requirements, and poor sealing effect. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing...
