The invention provides an end
butt joint type
loop heat pipe which is mainly being characterized by comprising a loop
pipe body, an inserting and sleeving type
butt joint part, an inserting gap and a degassing
pipe. The outside of the loop
pipe body is bent into a hollow
square shape, and the loop pipe body comprises a first pipe end, a second pipe end and a loop section. The inserting and sleeving type
butt joint part is formed in the manner that the first pipe end and the second pipe end of the loop pipe body serve as an inner pipe and an outer pipe to be inserted and sleeved oppositely in a sealed manner, and any one of the first pipe end and the second pipe end is arranged in the manner that the pipe
diameter is enlarged, and provided with a pipe enlarging part. The inserting gap is formed at the position of the radial local part between the first pipe end and the second pipe end, and penetrates the outside of the inserting and sleeving type butt joint part and a loop flow pass space in the loop pipe body. The degassing pipe is inserted into the inserting gap in a close fit manner to serve as a vacuumizing and working solution pouring channel, and the outer end of the degassing pipe extends out of the inserting and sleeving type butt joint part and is provided with a closed part. The structure of the
loop heat pipe can achieve practical progress of member simplification, easier and faster manufacturing,
machining and forming and substantial
manufacturing cost reduction, and achieve better industrial economy benefits.
