The method includes the step of providing a heat-transfer block and a plurality of heat pipes. A plurality of heat pipe grooves is formed on the heat-transfer block. The heat pipes are then press-fitted to respective heat pipe grooves. During the press-fitting step, the heat pipes are flattened to force the flattened part of one heat pipe into abutment against the flattened part of another heat pipe in a flushed manner. Thereby, the heat pipes are abutted to each other with no separation therebetween. Hence, the heat transfer performance is increased. ## Claims ### Claim 1 A heat pipe assembly, comprising: a heat-transfer block having a surface, a plurality of closely arranged heat pipe grooves formed on the surface, a plurality of supporting ribs each formed between two consecutive ones of the heat pipe grooves, and a tip portion formed on each of the supporting ribs; and a plurality of heat pipes press-fitted into respective heat pipe grooves, an abutting portion being formed on each of the heat pipes along each tip portion of the adjacent supporting rib, the abutting portions of consecutive ones of the heat pipes are flushed against one another. ### Claim 2 (depends on 1) The heat pipe assembly as claimed in claim 1, wherein the surface is defined as a bottom surface of the heat-transfer block. ### Claim 3 (depends on 2) The heat pipe assembly as claimed in claim 2, wherein a top surface is formed on the heat-transfer block opposite to the bottom surface, and wherein a plurality of heat-dissipating fins is disposed on the top surface of the heat-transfer block. ### Claim 4 (depends on 1) The heat pipe assembly as claimed in claim 1, wherein the heat pipe grooves of the heat-transfer block are arched to have a cross section slightly larger than a semi-circle. ### Claim 5 (depends on 1) The heat pipe assembly as claimed in claim 1, wherein the tip portion of each of the supporting ribs of the heat-transfer block is short of flushing coplanarly with the bottom surface of the heat-transfer block. ### Claim 6 (depends on 1) The heat pipe assembly claimed in claim 1, wherein a protrusion is formed on the supporting rib toward one of the adjacent heat pipe grooves. ### Claim 7 (depends on 1) The heat pipe assembly as claimed in claim 1, wherein a protrusion is formed on the supporting rib toward each of the adjacent heat pipe grooves. ### Claim 8 (depends on 1) The heat pipe assembly as claimed in claim 1, wherein at least one fixing rib is formed on each of the heat pipe grooves. ### Claim 9 (depends on 6) The heat pipe assembly as claimed in claim 6, wherein at least one fixing rib is formed on each of the heat pipe grooves. ### Claim 10 (depends on 7) The heat pipe assembly as claimed in claim 7, wherein at least one fixing rib is formed on each of the heat pipe grooves. ### Claim 11 (depends on 8) The heat pipe assembly as claimed in claim 8, wherein the fixing rib impresses into the corresponding heat pipe and forms an impression thereon. ### Claim 12 (depends on 9) The heat pipe assembly as claimed in claim 9, wherein the fixing rib impresses into the corresponding heat pipe and forms an impression thereon. ### Claim 13 (depends on 10) The heat pipe assembly as claimed in claim 10, wherein the fixing rib impresses into the corresponding heat pipe and forms an impression thereon. ### Claim 14 (depends on 1) The heat pipe assembly as claimed in claim 1, wherein the abutting portions of two consecutive heat pipes cover the tip portion of the corresponding supporting rib. ### Claim 15 (depends on 1) The heat pipe assembly as claimed in claim 1, wherein a heat-absorbing surface is formed on each of the heat pipes and is exposed from the corresponding heat pipe groove. ### Claim 16 (depends on 15) The heat pipe assembly as claimed in claim 15, wherein a protruding block is disposed on the heat-absorbing surface of each of the heat pipes, wherein the protruding blocks are arranged in parallel.
