  The present invention relates to a heat dissipation module.

  Electronic components such as a central processing unit (CPU), south bridge and north bridge chip sets, and video chip sets used in notebook personal computers generate heat during operation. For this reason, heat is radiated by combining a heat radiating module or using a heat radiating fan to ensure stable operation.

  Conventional heat dissipation modules usually include a heat transfer base, heat transfer tubes, and heat dissipation fins, or further include a heat dissipation fan.

In addition, the groove (or the through hole) of the heat transfer base and the inner surface of the groove surface (or the hole wall of the through hole) of the groove are both flat, and the corresponding outer wall surface of the heat transfer tube is also formed. Because of the flat shape, the stability of the heat absorption part of the heat transfer tube and the heat transfer base is not ideal, and the heat absorption part of the heat transfer tube moves loosely and easily causes poor contact. For this reason, there is a problem in that the heat of the component cannot be effectively transmitted to the radiating fin portion, and the overall heat transfer effect is not good.

  In order to solve the above problems, an object of the present invention is to provide a heat dissipation module that further simplifies the overall combination and enhances the heat transfer effect.

  In order to achieve the above object, a heat dissipation module according to the present invention includes a heat transfer base, a heat transfer tube having a heat absorption portion at one end and a heat dissipation portion at the other end, and a heat dissipation fin portion. A heat dissipation fan is provided. The heat transfer base has a concave groove in which a fitting convex part is formed. The heat absorption part of the heat transfer tube is fitted along the bottom surface of the concave groove, and is engaged with the fitting convex part to be coupled to each other, thereby stably coupling the heat absorption part and the concave groove of the heat transfer tube. The heat radiating portion of the heat transfer tube penetrates or fits into the heat radiating fin portion. Thereby, the coupling | bonding between each components of a thermal radiation module becomes tighter than a prior art.

In addition, a plurality of fins of the heat dissipating fin portions are formed with insertion grooves by the cut portions.
The fixed piece of the heat dissipating fan is quickly fitted into the fitting groove of the heat dissipating fin portion by the curved piece provided on the exhaust side. Thereby, the fitting coupling | bonding of a thermal radiation fan and a thermal radiation fin part can be achieved, and the combination of the whole thermal radiation module can further be simplified.

  The engaging protrusion in the groove is formed in a regular or irregular rib shape, formed in a regular or irregular intermittent rib shape, or distributed regularly or irregularly. Although it is formed in a plurality of protrusions, it is engaged with and fitted with the heat absorbing portion of the heat transfer tube without being limited thereto.

  The heat radiating fin portion is composed of a plurality of fins, and a cut portion is formed in the plurality of fins, and a fitting insertion groove is formed from the cut portion. The fixed piece of the heat radiating fan has a curved piece that is inserted into the fitting groove of the radiating fin portion and fitted on the exhaust side. By inserting the curved piece into the insertion groove of the radiating fin portion, the radiating fan is stably fitted to the radiating module, and the combination of the radiating module and the radiating fan can be simplified.

  The fixed piece of the heat dissipating fan has a connecting ear piece fixed to the heat dissipating fin portion. By fixing the connecting ear piece to the radiating fin portion, the stable coupling between the radiating fan and the radiating fin portion is strengthened, and the fixed piece is prevented from moving from side to side. You may fix a connection ear piece using a screw or a rivet.

The heat transfer tubes are fitted into two or more heat transfer bases and transmit heat of components connected to the two or more heat transfer bases.
Two or more concave grooves are formed in the heat transfer base. As a result, the plurality of heat transfer tubes can be fitted into the plurality of grooves, and can be engaged with and fitted to the fitting protrusions.

  The heat transfer base has an irregular surface, and an attached heat radiating fin is provided on the bottom surface or a plurality of heat radiating granular convex bodies are provided. Thereby, the heat transfer base can enhance the heat dissipation effect.
