When adopting technique scheme to produce, directly adopt prefabricated Al squeezing material and aluminium section bar, specification, mainboard size, installing space by the coupling electronic device cut Al squeezing material and aluminium section bar is made heat-sink unit, thermal-arrest unit and heat transfer unit respectively, after wearing heat pipe, be connected raceway groove and fin are chimeric one by one again, in case of necessity to chimeric place weld, bonding or punching press fixes; During use, the thermal-arrest unit cooperates with the heating face of electronic device, and the heat that electronic device work produces is dispersed rapidly by the pathway of " thermal-arrest unit-heat pipe-heat transfer unit-heat-sink unit-air ".

The utility model also provides a kind of inserted type radiator that does not use heat pipe, comprising:

The thermal-arrest unit is aluminium section bar, and its bottom surface has some raceway grooves;

Heat-sink unit is Al squeezing material, has substrate, have some fin that are arranged in parallel in the substrate, the raceway groove of the upper edge of fin and thermal-arrest unit is chimeric mutually one by one, and substrate self also has at least one section and cuts dummy section, and the fin that cuts in the dummy section constitutes grid type air channel.

For the ease of radiator is installed, also can further cut out a boss in the fin upper edge of heat-sink unit, the raceway groove of thermal-arrest unit is chimeric mutually by upper edge and each fin of boss.

When adopting technique scheme to produce, directly adopt prefabricated Al squeezing material and aluminium section bar, cut Al squeezing material and aluminium section bar by specification, mainboard size, the installing space of coupling electronic device and make heat-sink unit, thermal-arrest unit respectively and be connected raceway groove and fin are chimeric one by one again, in case of necessity to chimeric place weld, bonding or punching press fixes; During use, the thermal-arrest unit cooperates with the heating face of electronic device, and the heat that electronic device work produces is dispersed rapidly by the pathway of " thermal-arrest unit-heat-sink unit-air ".

Compare with prior art, the beneficial effects of the utility model are:

(1) all adopts aluminium section bar or Al squeezing material, do not need die sinking again can obtain the shape and the specification of appointment, reduced the Mold Making cost;

(2) can cooperate with heat pipe is chimeric, heat pipe need not flattened, handling ease, and assembling is flexible, and radiating efficiency is higher, good stability.

(3) heat-sink unit adopts Al squeezing material directly to make fin, reduces a lot of waste materials than milling fin on integrated section.
