For overcoming the shortcoming of above-mentioned prior art, fundamental purpose of the present utility model is to provide a kind of holding unit simple in structure, easy-to-install.

Another purpose of the present utility model is to provide a kind of holding unit that is easy to open.

Another purpose of the present utility model is to provide a kind of heating radiator that makes entirely to be sticked at the holding unit of central processing unit.

For reaching above-mentioned and other purpose, holding unit described in the utility model comprises: fixture, include the base of at least one accommodation space, extended upward stator respectively in two corresponding sides of this base, this stator is provided with articulated section and lower protruding block; And press part, be hubbed on the articulated section of fixture, stator both sides corresponding to this base are extended with sheet on one side respectively downwards to this press part in lid frame both sides, and the lower protruding block with respect to upper protruding block is arranged on this limit sheet, and this press part and this fixture are combined closely when making the mutual snapping of this upper and lower projection.

In addition, this press part also comprises being hubbed on and lifts the frame sheet on this lid frame, lift frame sheet both sides at this and respectively be provided with a push pedal, can by on lift this and lift the frame sheet and the push pedal of its both sides is pushed away cut and buckle knot upper and lower projection together so that raise this holding unit.

Brought forward is described, be nested with the holding unit outside this central processing unit, earlier press part is started, then with in the smooth accommodation space of inserting this fixture of heating radiator, again press part is pushed downwards afterwards, by the upper protruding block of this press part and the lower protruding block button knot of fixture, heating radiator is fixed in this holding unit.If will open this press part, then can by on lift this handle, make between the push pedal incision button knot upper and lower projection together of these handle both sides, can raise this press part.

Holding unit described in the utility model is simple in structure, and whole erection, opening operation process are simple, and this heating radiator is stressed evenly is sticked on central processing unit, has better result of use than prior art.
