Abstract
The application discloses a micro-pipe type liquid cooling heat exchanger and a production method thereof. The micro-pipe type liquid cooling heat exchanger comprises a shell, a cover and a plurality of micro-pipes. The cover is installed at the end of the shell. The cover comprises a cover seat, a first lining plate and a second lining plate. The cover seat comprises an abutting surface. The first lining plate and the second lining plate are stacked between the abutting surface and the shell. The first lining plate is located between the second lining plate and the abutting surface. The first lining plate is provided with a plurality of through holes. The second lining plate is provided with a plurality of through holes. The through holes are in one-to-one correspondence and are communicated. The outer diameter of the micro-pipe is larger than the through hole. The end of the micro-pipe extends into the through hole and is blocked and limited by the first lining plate. The application can meet the heat exchange demand of new energy vehicles.
