Description

Combined radiating device

[technical field]

The relevant a kind of combined radiating device of the utility model is meant a kind of combined radiating device that is applied to the heat radiation of curved surface thermal source especially.

[background technology]

Present industrial products field is the electronic product field particularly, the design of product is variation day by day, function from strength to strength, working loss is increasing, corresponding, the power consumption of heater members is having the trend of increase under the situation mostly, so become a kind of necessity and effective means for crucial heater members cooling.But the design of existing heat abstractor is that the situation on plane designs at the thermal source face often, when the thermal conductive surface that runs into heat generating component, assembly is the restriction of the situation of curved surface or mechanism aspect, often have to reduce the headspace of heat abstractor because of the restriction of mechanism, like this then efficiently radiates heat area heat abstractor certainly will reduce, thereby has had a strong impact on the performance of whole radiating effect and even product.From the manufacturing process of heat abstractor, three kinds of methods are arranged generally: aluminium extruded type, die-casting die and combination shape.Aluminium extruded type and die casting moulding are limited to the consideration of mechanical process capacity and cost, it is very thin that the thickness of fin can't be done, so then the efficiently radiates heat area is limited, therefore radiating effect can be had a greatly reduced quality. and knockdown heat abstractor can radiating fin do very thin, and can make up the intensive storehouse of radiating fin, thereby in limited space, enlarge the efficiently radiates heat area as much as possible.So knockdown heat abstractor is that the field on plane has very widely and uses at thermal source, but the realization of knockdown heat abstractor has a great problem, promptly the thermal conductive surface of heat abstractor is difficult to combine closely with the thermal source curved surface of curve form.

In view of this, having in fact to provide a kind of combined radiating device, is difficult to a difficult problem of combining closely with the thermal source curved surface of curve form to overcome the thermal conductive surface of heat abstractor in the prior art.

[summary of the invention]

The utility model purpose is to provide a kind of combined radiating device, is difficult to a difficult problem of combining closely with the thermal source curved surface of curve form to overcome the thermal conductive surface of heat abstractor in the prior art.

For reaching above-mentioned purpose, the utility model provides a kind of combined radiating device, in order to the curved surface thermal source is dispelled the heat, this combined radiating device is articulated by some radiating fins and combines, and be respectively equipped with heat radiator body on these radiating fins, one end of this heat radiator body connects a heat-conducting plate, and this heat-conducting plate and heat radiator body form an angle.According to spatial limitation and the actual needs that ventilate, this angle can be set to the arbitrary proper angle in 0～180 ° of scope.Establish first articulated part in the outside, position that this heat-conducting plate engages with heat radiator body, and on the heat-conducting plate free end edge, establish second articulated part, this second articulated part system articulates mutually with first articulated part, promptly is articulated mutually with this first articulated part and second articulated part between its several radiating fins.

Compared with prior art, the utility model utilizes the principle of calculus, the fritter plane that the thermal source curved surface is decomposed into is one by one treated, the radiating fin unit is set and these radiating fin unit are articulated combination mutually at this fritter plane, and allow each after radiating fin all can be around its radiating fin moving the preceding, then the thermal conductive surface of the combined radiating device of being made up of a plurality of heat-conducting plates just can bend to the arbitrary surface shape along with the curvature of curved surface thermal source as the joint, thereby the thermal conductive surface of heat abstractor is able to combine closely with the thermal source curved surface of curve form, and manufacturing process is simple, it is convenient to assemble, and can be widely used in curved surface heat radiation field.

For making the purpose of this utility model, structural feature and function thereof there are further understanding, cooperate diagram to be described in detail as follows now:

[embodiment]

The monomer perspective view of the combined radiating device that provides for the utility model and the perspective view of combined radiating device are provided shown in Fig. 1,2.The utility model is a kind of combined radiating device, it is combined by some radiating fins 10, these radiating fins 10 are respectively equipped with a heat radiator body 102, these heat radiator body 102 1 ends are equipped with a heat-conducting plate 101 respectively, these heat-conducting

plates

101 and and 102 of heat radiator body in a certain angle, according to spatial limitation and the actual needs that ventilate, it is the interior arbitrary proper angle of 0～180 ° of scope that this angle can be set to.Present embodiment is made as 90 °, and these heat radiator body 102 are provided with first articulated part 1010 with heat-conducting plate 101 joints, this first articulated part 1010 can be a rotating shaft (as shown in Figure 1), or a lug (as shown in Figure 4) that protrudes heat-conducting plate 101, no matter is that rotating shaft or lug are all and are stamped to form.

Moreover, these heat-conducting plates 101 then are not respectively equipped with one second articulated part 1011 with the free ora terminalis that heat radiator body 102 is joined, this second articulated part 1011 is corresponding with first articulated part, 1010 positions and cooperate in order to mutual pivot joint, is crotch (as shown in Figure 1) and via hole (as shown in Figure 4) in present embodiment.Above-mentioned first articulated part 13 and second articulated part can be established at least one group, for ease of articulating better between the radiating fin, are provided with the first hinge spare 1010 and the second corresponding articulated part 1011 of two groups of position symmetries in the present embodiment.

During combination, please refer to shown in Fig. 2,3,5, earlier first articulated part 1010 of a radiating fin 10 and second articulated part 1011 of another radiating fin 10 are articulated, look the thermal source surface 200 of thermal source 300 again, some radiating fins 10 are articulated, again the radiating fin of combining 10 is placed on the thermal source surface 200, because of 10 of these radiating fins are by articulating combination, so, act on as the joint, can change angle with thermal source surface 200, and then be close on the thermal source surface 200, to reach the purpose of rapid heat radiation.
