摘要

#CMT# #/CMT# The cooling unit (1) has a base plate (11) comprising a flat surface (111), which forms a groove (1111). The groove comprises an open side (1111a) and a closed side (1111b). A connecting part (112) is formed at a joint of the groove and the flat surface. A heat pipe (12) is arranged in the groove, and comprises a side surface (121), which is aligned to the flat surface. A mounting structure (13) is arranged on the connecting part. A side of the mounting structure is provided with a rough surface. The base plate is made of metal e.g. copper or aluminum, or non-metal i.e. plastic. #CMT# : #/CMT# An independent claim is also included for a cooling unit manufacturing method. #CMT#USE : #/CMT# Cooling unit. #CMT#ADVANTAGE : #/CMT# The base plate comprises the flat surface, the heat pipe is arranged in the groove and comprises the side surface, which is aligned to the flat surface, and the mounting structure is arranged on the connecting part, thus increasing connection strength of the base plate and a cooling element without utilizing additional attachment elements, and hence reducing manufacturing time and manufacturing cost of the cooling unit. The cooling unit exhibits reduced weight and scrap rate, and is utilized in an environment-friendly manner. The base plate is made of copper and aluminum, so that the cooling unit exhibits better thermal conductivity. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an exploded perspective view of a cooling unit. 1 : Cooling unit 11 : Base plate 12 : Heat pipe 13 : Mounting structure 111 : Flat surface 112 : Connecting part 121 : Side surface 1111 : Groove 1111a : Open side of groove 1111b : Closed side of groove.
