Abstract
The utility model relates to the field of electronic packaging, particularly to a graphite cooling sheet packaged by glass cement. The cooling sheet includes a first graphite heat conductive sheet, a highly heatproof protective film, and a first propylene double-sided adhesive layer which is adhesive on both faces. The protective film is arranged on the upper end of the first graphite heat conductive sheet, and the first propylene double-sided adhesive layer is bonded with the lower end of the first graphite heat conductive sheet. During assembling, as the bottom layer of the cooling sheet is the first propylene double-sided adhesive layer, the cooling sheet can be directly bonded with an electronic component. Peeling is not necessary, so that there is no waste.
Description
Technical field
The utility model relates to Electronic Packaging field, relates in particular to a kind of glass cement encapsulation graphite heat radiation fin.
Background technology
Graphite heat radiation fin has been widely used in the chip of mobile device, graphic process unit, or the locational cooling of battery supply is processed.Current glass cement encapsulation graphite heat radiation fin comprises graphite linings, layers of two-sided, peeling paper.Graphite linings plays thermolysis, and layers of two-sided plays fixation, and peeling paper plays protection glue.Glass cement is being encapsulated when graphite heat radiation fin is assembled on original paper and peeling paper need to peeled off, and peeling paper is utterly useless after using, and causes waste.
Utility model content
The purpose of this utility model is to provide a kind of glass cement encapsulation graphite heat radiation fin, solves the problem of making waste after peeling paper is stripped from.
For reaching this object, the utility model by the following technical solutions:
A glass cement encapsulation graphite heat radiation fin, comprises the first graphite heat-conducting fin, also comprises high heat-resisting protective film, the first propylene class layers of two-sided of can two sides pasting; Described high heat-resisting protective film is arranged at described the first graphite heat-conducting fin upper end, and described the first propylene class layers of two-sided is adhered to described the first graphite heat-conducting fin lower end.
Wherein, the thickness of described glass cement encapsulation graphite heat radiation fin is more than or equal to 53 millimeters, is less than or equal to 57 millimeters.
Wherein, described glass cement encapsulation graphite heat radiation fin is rolled into circle before using.
Wherein, described glass cement encapsulation graphite heat radiation fin is rolled into ellipse before using.
Wherein, described glass cement encapsulation graphite heat radiation fin is rolled into rectangle before using.
Wherein, the model of described the first graphite heat-conducting fin is GSM.
Wherein, the model of described the first graphite heat-conducting fin is LGS.
Wherein, the model of described the first graphite heat-conducting fin is HC.
The beneficial effects of the utility model:
Glass cement of the present utility model encapsulation graphite heat radiation fin, comprises the first graphite heat-conducting fin, also comprises high heat-resisting protective film, the first propylene class layers of two-sided of can two sides pasting; Described high heat-resisting protective film is arranged at described the first graphite heat-conducting fin upper end, and described the first propylene class layers of two-sided is adhered to described the first graphite heat-conducting fin lower end; When assembling, the bottom that encapsulates graphite heat radiation fin due to described glass cement is described the first propylene class layers of two-sided, can directly be bonded on electronic devices and components, does not need to peel off, and therefore can not produce waste; And traditional glass cement encapsulation graphite heat radiation fin bottom is one deck peeling paper, before use, need described peeling paper to peel off, and described peeling paper is disposable, just useless after peeling off, therefore cause waste.
Accompanying drawing explanation
Fig. 1 is glass cement encapsulation graphite heat radiation fin structure chart of the present utility model.
Fig. 2 is existing glass cement encapsulation graphite heat radiation fin structure chart.
The Reference numeral of Fig. 1 and Fig. 2 comprises:
The high heat-resisting protective film of 1-; 2-the first graphite heat-conducting fin; 3-the first propylene class layers of two-sided; 4-the second graphite heat-conducting fin; 5-dienes layers of two-sided; 6-peeling paper.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.Be understandable that, specific embodiment described herein is only for explaining the utility model, but not to restriction of the present utility model.It also should be noted that, for convenience of description, in accompanying drawing, only show the part relevant to the utility model but not entire infrastructure.
In conjunction with Fig. 1 and Fig. 2, glass cement encapsulation graphite heat radiation fin of the present utility model is elaborated.
Glass cement of the present utility model encapsulation graphite heat radiation fin, comprises the first graphite heat-conducting fin 2, also comprises high heat-resisting protective film 1, the first propylene class layers of two-sided 3 of can two sides pasting; Described high heat-resisting protective film 1 is arranged at described the first graphite heat-conducting fin 2 upper ends, and described the first propylene class layers of two-sided 3 is adhered to described the first graphite heat-conducting fin 2 lower ends.Traditional glass cement encapsulation graphite heat radiation fin comprises the second graphite heat-conducting fin 4, the dienes layers of two-sided 5, peeling paper 6; Traditional glass cement encapsulation graphite heat radiation fin needed described peeling paper 6 to peel off before using, and described peeling paper 6 is utterly useless after using, and causes waste; Glass cement encapsulation graphite heat radiation fin of the present utility model is when assembling, and the bottom that encapsulates graphite heat radiation fin due to described glass cement is described the first propylene class layers of two-sided 3, can directly be bonded on electronic devices and components, does not need to peel off, and therefore can not produce waste.And traditional glass cement encapsulation graphite heat radiation fin bottom is one deck peeling paper, before use, need described peeling paper to peel off, and described peeling paper is disposable, just useless after peeling off, therefore cause waste.1 pair of described the first graphite heat-conducting fin 2 of described high heat-resisting protective film plays a protective role, and avoids described the first graphite heat-conducting fin 2 in use and damages because of collision or cut, affects it to use normally; And the heat dispersion of described high heat-resisting protective film 1 and resistance to elevated temperatures better, can guarantee normal heat radiation, and can not damage self because of high temperature action.
