Another purpose of the present utility model is to provide a kind of radiator, the absorber plate upper surface of the set cooling base of mat central authorities is formed with storage tank, can be optionally and the cooling base of stacked smaller size smaller, to satisfy radiating requirements in various degree, to obtain maximum heat sinking benefit.

A purpose more of the present utility model is to provide a kind of radiator, and the four side of the set cooling base of mat directly cuts, backfin forms most thermal columns, and can save man-hour, material and reducing cost.

Another purpose of the present utility model is to provide a kind of radiator, and the set cooling base of mat central authorities form the cooling base of storage tank with stacked smaller size smaller, can be with the volume of minimum, and increase maximum cooling surface area.

For achieving the above object, the utility model is achieved through the following technical solutions: a kind of radiator, mainly be by a cooling base be the basis, this cooling base is the groove shape body that is square, cut backfin respectively in its four side and be formed with most thermal columns, be formed with storage tank in centre, its bottom is flat absorber plate; It is characterized in that: this majority thermal column is directly upwards to be the three-dimensional rectangular column that is staggered front to back arrangement from cooling base cutting and backfin, and its quantity that effluxes is more than interior row's quantity.

Storage tank has accommodation space.

The nested fixing backstay of cooling base for smaller size smaller is set on the storage tank.

By the utility model radiator, overcome the shortcoming of prior art, reached the purpose of above-mentioned creation, the utility model can be saved material, reduce cost, and heat extraction speed is very fast, has effectively increased area of dissipation, to satisfy radiating requirements in various degree, the utility model has been given full play to the radiator function, to obtain maximum radiating effect, has solved the computer components problems of excessive heat really.
