Abstract

The utility model relates to a radiator comprising a base plate, a plurality of radiating tablets arranged on the base plate vertically and separately, each radiating tablet is convexly provided with a plurality of first convex parts in separation and a plurality of second convex parts arranged convexly between two adjacent first convex parts, the first convex parts and the second convex parts are in cohesion with each other so that the radiating area of all the radiating tablets can be increased and the radiating efficiency can be further improved.

Description

Heating radiator

[technical field]

The utility model relates to a kind of heating radiator, is meant that especially a kind of area of dissipation increases, and then can improves the heating radiator of radiating efficiency.

[background technology]

Computing machine is when using, because central processing unit and other compute chip of main frame inside operate apace, disengage a large amount of heat, and this general main frame major part is a hemi-closure space, can't be effectively that heat release is extremely extraneous, for preventing hot excessive accumulation, influence the running of central processing unit and compute chip, even the situation of burning, must on heat generating component, install heat abstractor, so that heat is dissipated to the external world, the heat abstractor kind that computing machine is used is many, heating radiator is wherein a kind of, the structure of general heating radiator as shown in Figure 1, comprise the substrate 21 on the heat generating component 1 of being located at central processing unit exclusive disjunction chip, and a plurality of upright and compartment of terrains are built in the heat radiator 22 on this substrate 21, by contacting of this substrate 21 and this heat generating component 1, the heat conduction that this heat generating component 1 is generated is to this substrate 21, reach these heat radiator 22 again, and heat is dissipated in the ambient air by the surface of each heat radiator 22, so the area of these heat radiator 22 and radiating effect have absolute relation, the area of heat radiator 22 is big more, radiating effect is good more, therefore, and often in order to support high-revolving heat generating component, then strengthen the length and width size of each heat radiator, cause the heating radiator volume to increase, take up space very much, practicality is not good.

[utility model content]

The purpose of this utility model is to provide a kind of heating radiator that improves radiating efficiency.Of the present utility model being characterised in that: this heating radiator includes a substrate, and a plurality of upright and compartment of terrain is built in the heat radiator on this substrate.Each heat radiator all has first protuberance that a plurality of intervals are convexly equipped with, and a plurality of second protuberances that oppositely are convexly set between two adjacent first protuberances, adjacent first protuberance and second protuberance are engaged togather, form the continuous wave shape wave, so that all heat radiator have bigger area of dissipation, and then promote radiating efficiency.

[description of drawings]

Below by most preferred embodiment and accompanying drawing heating radiator of the present utility model is elaborated, in the accompanying drawing:

Fig. 1 is that general heating radiator is installed in the synoptic diagram on the heat generating component.

Fig. 2 is the synoptic diagram of first preferred embodiment of the present utility model.

Fig. 3 is the synoptic diagram of a heat radiator in the utility model first preferred embodiment, display base plate part not among the figure.

Fig. 4 is the synoptic diagram of second preferred embodiment of the present utility model.

Fig. 5 is the synoptic diagram of a heat radiator in second preferred embodiment of the present utility model, display base plate part not among the figure.

[embodiment]

As Fig. 2,3, heating radiator 3 of the present utility model can be used on the heating electronic package of electronic installation, especially can be used on the heating electronic package of computing machine or server, such as CPU (central processing unit) (CPU), first preferred embodiment of the present utility model is to comprise: a substrate 31 and a plurality of upright and compartment of terrain are built in the heat radiator 32 on this substrate 31, the length of each heat radiator 32 is to having a horizontal imaginary line first-first, the horizontal imaginary line first-first of each heat radiator 32 is to be parallel to each other in this preferred embodiment, as seen from Figure 3, first protuberance 321 that a plurality of intervals are convexly equipped with is formed at a side of horizontal imaginary line first-first, and a plurality of second protuberances 322 that oppositely are convexly set in 321 of two adjacent first protuberances are formed at the opposite side of horizontal imaginary line first-first, two adjacent

first protuberance

321 and 322 of second protuberances are to be engaged togather, so these heat radiator 32 all are continuously wavy, as unrestrained plate, by all heat radiator 32 formed wave kenels, make each sheet heat radiator 32 all have bigger area of dissipation, can promote the efficient of heat radiation effectively than existing flat heat radiator.

In addition, the utility model also can second embodiment structure, reach identical effect, as Fig. 4, shown in 5, this heating radiator 4 has a substrate 41 and plural pieces and is located at heat radiator 42 on this substrate 41, do not exist together with first embodiment, the continuous wave that is all heat radiator 42 is along a vertical imaginary line second-second, as first embodiment, each heat radiator 42 has a vertical imaginary line second-second, the vertical imaginary line second-second of each heat radiator 42 is to be parallel to each other in this preferred embodiment, first protuberance 421 that a plurality of intervals are convexly equipped with is formed at a side of vertical imaginary line second-second, and a plurality of second protuberances 422 that oppositely are convexly set in 421 of two adjacent first protuberances are formed at the opposite side of vertical imaginary line second-second, two adjacent

first protuberance

421 and 422 of second protuberances are to be engaged togather, so these heat radiator 42 all are continuous wave aspect, as unrestrained plate, by all heat radiator 42 formed unrestrained template attitudes, make each sheet heat radiator 42 all have bigger area of dissipation, can promote the efficient of heat radiation effectively than existing flat heat radiator.

In first or second embodiment, the one side that heating radiator 3,4 can not contact with heat radiator 32,42 with substrate 31,41 respectively contacts with the electronic package of heating for a moment, leaves to heat radiator 32,42 with the heat conduction with this electronic package.

Conclude above-mentionedly, heating radiator of the present utility model is by be provided with a plurality of first protuberances and second protuberance on each heat radiator, can be under the situation that does not increase volume, make the area of dissipation of heat radiator strengthen, and then reach the effect that improves radiating efficiency, so very practical really and progressive.
