Abstract

The utility model discloses a fan latch device of a computer radiator and comprises a base and a complex number of radiation fins. The top surface of a radiation region of the complex number of radiation fins is fixed with a fan, and a fastener of the fixed fan comprises two shoe fasteners in the same shape. The shoe fastener is arranged at an angle of 90 degrees, and the left and right sides are in rectangular shape. Two sides of the upper end of the shoe fastener are respectively provided with a hook portion which is corresponding to a fan fixed hole, and the bottom edge of the shoe fastener is at least provided with the hook portion which is buckled on a buckle hole which is arranged on the outermost portion of the radiation fin. The hook portion of the upper end is connected with the hook portion of the lower edge through a curved elastic arm. The utility model is simple in construction, low in cost of manufacture, and the fan can be quickly locked and fixed on the radiation fin without any tools.

Description

The fan latching system of computer radiator

The utility model relates to a kind of fan latching system of computer radiator, is meant a kind of simple structure especially, and is easy to operate, and need not any instrument can fast fan assembly be fixed in a kind of radiator fan latching system of radiating fin top.

The known computer radiator relevant with the utility model as shown in Figure 1, this heating radiator 1 comprises: a pedestal 10, be fixed with a plurality of heat radiation eel sheets 20 at this pedestal 10, this radiating fin 20 is to be converted into upper/lower terminal by the sheet metal Curved Continuous to have the wavy square heat dissipation region of " U " shape bent angle, and fan 30 can be fixed thereon in this heat dissipation region end face middle position and combine.Be to contact with microprocessor (CPU) 40 on the motherboard during use by the central surface of contact 11 of pedestal 10 bottoms, and the thermal energy conduction that CPU produced in when running is gone out by this radiating fin 20, and can cooperate fan 30 that heat is loose outside host computer, to reach the purpose of heat radiation forcibly further.

Above-mentioned known computer radiator 1 is fixed in method on the radiating fin 20 with fan 30, as shown in Figure 1, owing on the radiating fin that is converted into sheet metal, can't be provided with screw or nut, so all add a framework 50 at radiating fin end face or periphery, offer a big ventilating opening 51 in framework central authorities again, corresponding with the fixed orifice 31 of fan 30, around it, be provided with screw 52, with screw 32 fan 30 is locked on the framework 50, so that radiating fin 20 is dispelled the heat.Above-mentioned known computer radiator, it must add a framework and with instrument fan is locked on the framework with screw when being fixed in fan on the radiating fin, and the manufacturing cost height is time-consuming, and constructing operation inconvenience.

Fundamental purpose of the present utility model promptly is to provide a kind of fan latching system of computer radiator, and its simple structure is cheap for manufacturing cost, and need not can apace fan be locked on the radiating fin by any instrument.

The purpose of this utility model is achieved in that a kind of fan latching system of computer radiator, comprise that a bottom can and be located at the plurality of radiating fins of base top surface with the contacted pedestal of microprocessor end face, on the formed heat dissipation region end face of this plurality of radiating fins, be fixed with fan, the fastener of fan attachment is made up of two identical fasteners of shape, each fastener is 90 °, about be rectangle, and respectively has a hook part corresponding to the fan fixed orifice in these fastener upper end two sides, in addition be provided with a hook part that is buckled in the default button hole of radiating fin outermost at least, and between the hook part of upper end and lower edge hook part, link by an arc elastic arm in the root edge of fastener.

When using according to above-mentioned tectonic association, the hook part of fastener upper end is inserted in the fixed orifice of fan, hook part with the fastener lower edge is pressed in the button hole of radiating fin outermost reservation in addition, by the elastic force of elastic arm therebetween fan is held on the radiating fin, and reaches the effect that easily and apace combination of fans is fixed on the radiating fin.

For making your juror more further understanding and understanding can be arranged, lift a preferable possible embodiments now and cooperate graphic being described in detail as follows structure of the present utility model, device and feature thereof:

Fig. 1 is the plane combination embodiment figure of known computer radiator.

Fig. 2 is a three-dimensional exploded view of the present utility model.

Fig. 3 is a three-dimensional combination figure of the present utility model.

Fig. 4 is plane combination embodiment figure of the present utility model.

See also Fig. 2,3 the utility model computer radiators 1 are to be assembled in the heat radiation that is used on the computer motherboard CPU, this heating radiator 1 mainly comprise one in the bottom can with the contacted pedestal 10 of microprocessor (CPU) end face, and be located at the plurality of radiating fins 20 of pedestal 10 end faces, end face in these plural number heat radiation eel sheet 20 zones that form is provided with a dented space 21, and a fan 30 can be contained in fully in this dented space 21 and be fixed, to reach the little kenel of easy combination and volume; The fastener of fan attachment 30 is made up of two identical fasteners 60 of shape, each fastener 60 is seen by side view and is 90 °, about then be rectangle, and respectively have the fixed orifice 31 of a hook part 61 corresponding to fan 30 in these fastener 60 upper ends two sides, in addition be provided with a hook part 62 at least and be buckled in the default button hole 22 of heat radiation eel sheet 20 outermost in the root edge of fastener 60, and in the hook part 61 of upper end and lower edge hook part 62 by an arc elastic arm 63 bindings.

Consult shown in Figure 4 again according to above-mentioned structure, when the utility model is equal to Fig. 1 kenel and is used in combination, be that the hook part 61 of fastener 60 upper ends is inserted in the fixed orifice 31 of fan 30, hook part 62 with the fastener lower edge is pressed in the button hole 22 of heat radiation eel sheet outermost reservation in addition, and by the elastic force of elastic arm 63 therebetween fan 30 is held on the radiating fin 20, and need not any instrument can be easily and reach apace effect on the radiating fin 20 is fixed in fan 30 combinations.The utility model can save the framework 50 of the known radiating fin top that adds as shown in Figure 1 can save making and material cost with screw 32 grades.

Claims

1, a kind of fan latching system of computer radiator, comprise that a bottom can and be located at the plurality of radiating fins of base top surface with the contacted pedestal of microprocessor end face, on the formed heat dissipation region end face of this plurality of radiating fins, be fixed with fan, it is characterized in that: the fastener of fan attachment is made up of two identical fasteners of shape, each fastener is 90 °, about be rectangle, and respectively has a hook part corresponding to the fan fixed orifice in these fastener upper end two sides, in addition be provided with a hook part that is buckled in the default button hole of radiating fin outermost at least, and between the hook part of upper end and lower edge hook part, link by an arc elastic arm in the root edge of fastener.
