Abstract
The utility model relates to a radiator of a non-ventilated central processing unit, and comprises a basal plate and a plurality of fins which are fixedly arranged on the basal plate. The utility model is characterized in that the cross-section of the fin is taken in the rectangle shape, the height is 42 to 48 mm, and the transverse gap and the longitudinal gap of the fin are 4.5-5.5 mm. The radiator of the non-ventilated central processing unit of the utility model does not need the fan, thereby the occupying space in a cabinet is small and the production cost of the set can be lowered.
Description
[technical field]
The utility model relates to a kind of radiator of central processing unit of computer, refers to a kind of radiator that does not have the central processing unit of fan especially.
[background technology]
The radiating mode of the central processing unit (CPU) of computer employing at present, it all is the active heat removal mode, promptly radiator is set in the CPU top, again in the radiator top or the side fan is installed, such radiator is because have distinguished and admirable pressure by having certain radiating effect, and its shortcoming is that to take the cabinet inside space bigger.
[utility model content]
The purpose of this utility model provides a kind of radiator that does not have the central processing unit of fan, can not use fan, thereby the space that takies cabinet inside is less, and can reduces the production cost of complete machine.
The utility model provides a kind of radiator that does not have the central processing unit of fan, comprises substrate and is fixedly arranged on the fin that the majority on the substrate is arranged, and it is characterized in that:
This fin cross section is rectangular, and it highly is 42-48mm, and the lateral clearance of this fin and axial clearance are 4.5-5.5mm.
The radiator of the central processing unit of described no fan is characterized in that:
One side one of this substrate is extended an auxiliary substrate, and this auxiliary substrate and this substrate have a difference in height, also is provided with most fins of arranging on this auxiliary substrate.
The radiator of the central processing unit of no fan of the present utility model, heat radiation applicable to lower-powered mainboard, for example mainboard is provided with central processing unit about 11W and the north bridge chips about 3W, the utility model is not because of using fan, thereby the space that takies cabinet inside is less, and can reduce the quantity of parts, reduce the complete machine production cost.
The no fan radiator of central processing unit of the present utility model is through the design data that calorifics theory is derived and numerical simulation calculation obtains, and can get a desired effect through test.In the test at system comprise the no fan power supply of a mainboard and a power 50W, this mainboard comprises that a heating is the central processing unit about 11W, heating is the north bridge chips about 3W, the TC allowable limit value of the CPU that uses is 85 degree, with no fan radiator of the present utility model, ambient temperature is that the TC value of 36 CPU that record when spending is 76 degree, less than allowable limit value, thereby has realized the heat dissipation problem of the central processing unit of a no fan.

Fig. 1 is the perspective view of preferred embodiment of the present utility model.
Fig. 2 is the front view of preferred embodiment of the present utility model.
Fig. 3 is the vertical view of preferred embodiment of the present utility model.
[embodiment]
With reference to Fig. 1,2,3, the radiator of the central processing unit of no fan of the present utility model, comprise the substrate 10 that is attached on the central processing unit 1 and be fixedly arranged on the fin 20 that the majority on the substrate is arranged, the about 7mm of the thickness of this substrate, these fin 20 cross sections are rectangular, its height h can be 42-48mm, and height h is 45mm in present embodiment, and the lateral clearance d1 and the axial clearance d2 of this fin 20 can be 4.5-5.5mm.Lateral clearance d1 and axial clearance d2 are 5mm in present embodiment.
Fin 20 height can not be too high, and the too high heat of bottom that will cause can not shed in the mode of convection current, and stays on the radiator, causes heat not loose very soon in air, causes the radiator heat to continue to raise.Fin 20 height can not be too short, and too short meeting causes area of dissipation not enough.The lateral clearance d1 and the axial clearance d2 of this fin 20 are extremely important in utilizing heat loss through convection, and too little gap causes thermal current to produce turbulent flow in the bottom, looses less than in the air, and too big gap causes the minimizing of number of fins, also can cause the rising of CPU heat.Above-mentioned numerical value all is through computer simulation analysis, relatively obtains repeatedly.
An auxiliary substrate 30 is established in the one side one extension of this substrate 10, and this auxiliary substrate 30 has a difference in height k with this substrate 10, also is provided with most fins of arranging 31 on this auxiliary substrate 30.This auxiliary substrate 30 is the spaces that are used for utilizing as much as possible in the cabinet, enlarges area of dissipation.
Claims (2)
1, a kind of radiator that does not have the central processing unit of fan comprises substrate and is fixedly arranged on the fin that the majority on the substrate is arranged, and it is characterized in that:
