Embodiment Construction

[0013] The following will take a notebook computer case as an example to describe a heat dissipation case and a manufacturing method thereof.

[0014] Please refer to Fig. 1, which is a notebook computer casing 100 provided by this embodiment. Fig. 1 shows that the notebook computer casing 100 is in a closed state, which includes a first side 12 and a third side 16 opposite to each other, and a side opposite to the third side 16. The second side 14 and a fourth side 18 .

[0015] The notebook computer case 100 is made of fiber polymer composite material, and the fiber polymer composite material is a composite material of fiber 20 and polymer resin material 30 . The polymer resin material 30 may be epoxy resin, unsaturated polyester, vinyl resin or phenolic resin and the like. The fibers 20 can be carbon fibers, glass fibers or metal fibers, etc., and the fibers 20 are arranged in parallel along the same direction. This embodiment is a carbon fiber epoxy resin composite mater...

Abstract

The case is made of composites of fiber high-molecule. The fibers are arranged in parallel along with a same direction; wherein, on the side face of the case vertical being perpendicular to the direction of the arranged fibers there is a metal film coated. The invention also reveals method of manufacturing the heat-radiating case.

Description

【Technical field】 [0001] The invention relates to a casing, in particular to a heat dissipation casing of an electronic product and a manufacturing method thereof. 【Background technique】 [0002] With the development of electronic products such as laptops and mobile phones in the direction of lightness, thinness, shortness, smallness, and intelligence, the processing speed of the central processing unit (CPU) and the number of peripheral electronic components continue to increase, resulting in constant heat generation. Increase. However, the internal space of electronic products such as notebook computers and mobile phones is narrow, and the heat generated continues to increase. If the heat cannot be dissipated effectively and in time, it will affect the working efficiency and service life of various electronic components. Therefore, the current combination of heat pipes and fins The heat dissipation methods of fans, fans, and shells have been widely used in the heat dissip...
