Abstract

A heat pipe mounting method and a heat pipe assembly thereof are disclosed. 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

1. A heat pipe mounting method, comprising the steps of:

a) providing a heat-transfer block and a plurality of heat pipes, a plurality of heat pipe grooves each having a bottom surface being formed on the heat-transfer block for each groove to respectively accommodate one of the plurality of heat pipes, a supporting rib being formed between every adjacent two of the heat pipe grooves, a tip portion being formed on each of the supporting ribs;

b) press-fitting the heat pipes into the respective heat pipe grooves; and

c) flattening a part of each of the heat pipes to force the flattened parts of the heat pipes into abutment against one another in a flushed-manner when press-fitting the heat pipes into respective heat pipe grooves, wherein the flattened part of each of the heat pipes extends along and over the tip portion of each of the adjacent supporting ribs, so that the flattened parts of the heat pipes are exposed for heat dissipation and coplanar and in direct contact with each other to form a single flat heat-absorbing surface, with the tip portions of the supporting ribs totally covered thereby.

2. The heat pipe mounting method as claimed in claim 1, wherein a protrusion is formed on the tip portion of each of the supporting ribs toward one of the two adjacent heat pipe grooves in step a).

3. The heat pipe mounting method as claimed in claim 1, wherein a protrusion is formed on the tip portion of each of the supporting ribs toward each of the two adjacent heat pipe grooves in step a).

4. The heat pipe mounting method as claimed in claim 1, 2 or 3, wherein at least one fixing rib is formed on and protruding from each of the heat pipe grooves in step a).
