The experiment of this thesis explores the cooling
capability of the heat pipe of P4 (Pentium4) RHE thermal module
in combination with cooling fins. Under the conditions of
established heat pipe thermal conductivity rate, heat
pipe-related size, fan capability curve, fin-related size
(such as length, spacing, thickness, number of fins and
material, We analyzed the cooling fin shape parameters, to
achieve bester RHE cooling effect.
The cooling fin shapes explored in this thesis have shapes
of A, B, C, D, and E. Of which are 43 regularly shaped A RHE
cooling fins, 43 new model B RHE cooling fins, 31 new model C
RHE cooling fins, 20 new model D RHE cooling fins, and 10 new model E RHE cooling fins.
Cooling designs, regardless of free convection or forced
convection, generally employ cooling fins to dissipate CPU heat
to the air. The key in the design is usually the convection
effect between cooling fins and the air. Therefore, the best
cooling effect is sought among the five cooling fins with different shapes.
Research analysis finds that a modified fin without
sufficient thermal diffusion surface will indirectly lower the
cooling efficiency of RHE. In the modified RHE thermal module
fin shape, the temperature of the RHE thermal module increased
between 2 to 4.6℃, the cooling efficiency decreased between
16.7 to 28.6%.
