Description of the Invention: [Technical Field] The present invention relates to a heat dissipation module, and more particularly to a heat dissipation module which has a high heat dissipation efficiency by changing the arrangement of heat dissipation fins. · [Prior Art] At this stage, the divergence problem has become an important issue that restricts the development of electronic components. The industry usually uses a heat dissipation module attached to a heat-generating electronic component to dissipate the electronic component. The conventional dilated group generally includes a plate body, a centrifugal fan and a plurality of fins disposed on the upper portion of the plate body, and a plurality of heat pipes disposed at a lower portion of the plate body. The towel, the fresh heat-dissipating fins are not placed in the air outlet of the centrifugal fan to form a rectangular heat-dissipating fin group. The heat officer includes an evaporation section on the upper part of the hair loss reduction member, a condensation section having a good thermal connection with the dispersion group, and a gambling-reduction between the evaporation section and the adiabatic section, and a bend between the condensation section and the adiabatic section. Folded to form a curved tube portion. During operation, the evaporation section of the heat f absorbs the heat generated by the heat-generating electronic component, and the heat is transmitted to the condensation section by the phase change of the working medium filled inside the heat pipe, and the heat at the condensation section is transmitted to the heat dissipation fin through the plate body. The heat in the heat sink fin group is radiated to the surrounding environment towel through the air convection between the heat sink fin group and the fan, thereby achieving heat dissipation to the electronic component B. In the heat dissipation process, the air convection between the heat dissipation fin group and the centrifugal fan is finally required to dissipate the heat. Therefore, the heat dissipation efficiency of the _ plate and the delocalized air is the key to the heat dissipation module design. The conventional method of improving the air convection between the fin group and the fan generally increases the area of the scatter between the fin group and the wind lying air. The specific method is to reduce the spacing between the loose sheets or increase the size of the single-sided sheet. These methods are capable of - to a certain extent, the heat dissipation tabs, 'and the air convection between the fans. However, 'the heat-dissipating fin group is rectangularly arranged, and the heat-conducting fin portion of the heat-conducting fin portion is small, so that the amount of heat received by the ship at the ship is less, so that the heat-emitting element is transmitted to the diffusing lens. The heat of the group, which in turn reduces the heat dissipation efficiency of the 6 1303968 heat sink. SUMMARY OF THE INVENTION The following is a specific embodiment.
