Description

Radiator base and heat pipe combination

The invention relates to a base of a heat sink combined with a heat pipe, in particular to a base system above and a lower substrate insert structure and a quick and stable combination with a heat pipe by punching to provide a central processing unit (CPU) or Other heat-generating electronic components are used for heat dissipation.

A heat sink with a heat pipe is usually used to embed (or penetrate or cover) the heat-absorbing end of the heat pipe into a heat-dissipating base, and the heat-dissipating end of the heat pipe can be connected to a heat-dissipating fin module to dissipate heat. The pedestal is attached to the central processing unit or other heat-generating electronic components, and the thermal temperature is guided to the heat-dissipating fin module for heat dissipation; the early technology mainly uses the solder joint to complete the combination of the heat pipe and the pedestal, and more recently The use of a chiseling technique, the heat pipe is directly embedded in a predetermined groove of the heat sink base, and the heat pipe can be exposed on the surface of the base; and the technology disclosed in the new patent No. M280631, which is a plurality of heats The conduit is sandwiched between the base and the cover plate, and after the base and the cover plate are correspondingly closed, the convex portions at both ends of the base are bent and deformed inward by being pressed by an external force, and then the sandwiched cover plate and the heat pipe are pressed. The fixed combination of the base and the heat pipe is achieved; however, the above-mentioned M280631 patent, because the convex portions at both ends of the base are subjected to a large pressing external force in an instant, it is easy to cause a convex deformation of the central portion of the upper cladding plate. Even the base The body may also have bending deformation, and no matter whether the superposed plate or the base is deformed, the plurality of heat pipes may not be stably clamped, so the heat pipe will inevitably have a gap between the base and the cover plate, and the fixing effect is not only fixed. Poor, and the thermal conductivity is also less than ideal.

A secondary object of the present invention is to provide a base of a heat sink and a heat pipe, wherein the upper and lower substrates are respectively provided with corresponding slots at adjacent intervals of the receiving grooves. Therefore, when the upper and lower substrates are press-bonded, the slot and the post can be synchronously coupled and integrated, so that the adjacent gaps of the accommodating recesses also form a occlusal engagement. The force of the lower substrate and the heat pipe combined with each other can be more uniform, and the upper and lower substrates can be prevented from being deformed.

Another object of the present invention is to provide a base of a heat sink and a heat pipe, wherein the upper and lower substrates are provided with a groove and a block, or a slot disposed at an interval between each groove and Inserting the post, the slot and the slot have a selected angle of inclination, and the insert and the post can be a vertical post, so that the insert and the post can be inclined at an angle when punching The slot and the slot guide the insertion, resulting in a tight engagement of the deformed bite.

Another object of the present invention is to provide a base of a heat sink and a heat pipe, wherein the upper and lower substrates are provided with grooves and inserts on both sides, and the block can be implemented as a single convex or The double convex vertical column, the groove system can be implemented as a corresponding single concave or double concave inclined groove, so when punching, the single convex or double convex vertical column can be inclined along the single concave or double concave inclined groove. The insert can be aligned with the guide insertion slot, and the deformation is tightly coupled to further strengthen the solid combination of the base and the heat pipe.

A further object of the present invention is to provide a base of a heat sink and a heat pipe, wherein the upper and lower substrates are provided with slots and posts at adjacent intervals of the grooves, and the slot can also be a slot. The groove is inclined so that the insertion post can be aligned with the guide insertion, and the deformation is tightly coupled to secure the solid base and the heat pipe.
