Abstract
The utility model relates to a high-performance heat radiator, which comprises a main body which is made of powder metallurgy; the main body forms a porous structure and can also be connected to a bottom plate in the mode gluing or welding; the main body can also be made into a casing shape, and the surface of the main body is treated into hair coat-shaped air holes, and thereby, maximum heat radiation area is available to reach better heat radiation effect and effectively help an electric heating element rapidly radiate the heat.
Description
The utility model relates to a kind of high-effect heat abstractor, particularly a kind ofly makes with powder metallurgy, has the heat abstractor of better heat dissipation effect.
Heat abstractor (or claiming heating radiator) is the device that a kind of assistance central processing unit electronic heating element radiatings such as (CPU) is used, it comprises a base plate 10a and a plurality of fin 11a of being connected on the base plate 10a constitute, general existing heat abstractor is mostly made in the aluminium extruded type mode, also fin can be bent into sheet metal, to increase area of dissipation.
But no matter above-mentioned existing heat abstractor is that aluminium extruded type or sheet metal are bent into, and its area of dissipation still is very limited, thus can't bring into play its best heat conduction efficiency, so its heat radiation can also have certain restriction.
Fundamental purpose of the present utility model, provide a kind of high-effect heat abstractor, it is that the body of heat abstractor is made with powder metallurgy, be densely covered with hole on this body, can obtain maximum area of dissipation, therefore can reach better radiating effect, dispel the heat rapidly to assist electronic heating elements such as central processing unit effectively.
Another purpose of the present utility model, be to provide a kind of high-effect heat abstractor, it is that the body of heat abstractor is made the housing shape, in order to casing as host computer or other electric equipment products, both can assist the heat radiation of host computer or electric equipment products internal heating element, can prevent electromagnetic interference (EMI) again.
For achieving the above object, the utility model provides a kind of high-effect heat abstractor, includes a body made from powder metallurgy, and this body forms a porous structure.
Now the embodiment shown in conjunction with the accompanying drawings describes structure of the present utility model and function in detail.Wherein:
Fig. 1 is the stereographic map of existing heat abstractor;
Fig. 2 is a stereographic map of the present utility model;
Fig. 3 is the stereographic map that another embodiment of the utility model is installed in host computer;
Fig. 4 is the sectional view of another embodiment of the utility model.
Symbol description:
10 bodies, 11 base plates, 12 bleeder vents, 20 casings
As shown in Figure 2, the utility model provides a kind of high-effect heat abstractor, it includes a body 10, this body 10 is to make with powder metallurgy with the good material of heat conductivity (as aluminum or aluminum alloy), to form as the porous structure of Sponge shape, that this body 10 can be is tabular, bulk or other different shapes, and the profile and the size of this body 10 do not limit, can do suitable variation with the need, its factor of porosity is healed, and then weight is lighter for height.
But modes such as this body 10 and mat thermal conductivity epoxy resin bonding or the molten aluminium welding of high temperature are linked on the base plate 11, make to have contact and heat conductivity preferably between body 10 and the base plate 11.
The utility model is in when installing, but the base plate 11 of mat heat abstractor directly fit on the electronic heating element, in order to assist heat radiation.Body 10 of the present utility model is to make with powder metallurgy.Be densely covered with hole on this body 10, can obtain maximum area of dissipation, therefore can reach better radiating effect, dispel the heat rapidly to assist electronic heating elements such as central processing unit effectively.
Moreover, shown in Fig. 3 and 4, the body 10 of the utility model heat abstractor also can be made into the shelly body, in order to casing 20 as host computer, and body 10 (casing 20) surface can be processed into the bleeder vent 12 of lint shape, this heat abstractor is used the casing 20 of host computer, both can assist the heat radiation of host computer internal heating element, if this heat abstractor is made with aluminium alloy, can prevent from again to disturb, certain heat abstractor of the present utility model also can be applicable to the casing of laptop or other electric equipment products.
In sum, the utility model has overcome the defective of existing heat abstractor, and its area of dissipation is bigger, so have higher heat conduction efficiency.
