Abstract

The invention relates to an electronic device comprising a main board, a first radiator, a second radiator, and two elastic fixed elements. The first radiator includes a substrate and a plurality of cooling fins arranged at the top of the substrate. The second radiator consists of a first connecting plate, a plurality of cooling fins arranged at the top of the first connecting plate, and two fixed blocks respectively arranged at the two ends of the first connecting plate; and the two fixed blocks are contacted to the main board. The first radiator is assembled at the main board; and the two fixed elements can be in an elastic deformation mode and two ends of each fixed element are respectively abutted against the substrate and the fixed blocks. According to the electronic device, the first radiator presses the fixed elements and thus the second radiator is fixed at the main board; screw hole opening is not required; and convenience is realized.

Description

Electronic installation

Technical field

The present invention relates to a kind of electronic installation.

Background technology

Central processing unit one side of mainboard is standing has electronic component that some caloric values are large (as VR-MOS, the Voltage Supply Device of voltage is provided) and pass by screw the radiator that mainboard is installed promising these electronic element radiatings, not only loaded down with trivial details, also easily affect the cabling on mainboard, very inconvenient.

Summary of the invention

In view of more than, be necessary to provide a kind of electronic installation that facilitates fixed heat sink.

A kind of electronic installation, comprise a mainboard, one first radiator, one second radiator and the flexible fixture of two tools, this first radiator comprises a substrate and is located at some radiating fins of the end face of this substrate, this second radiator comprises one first brace, be located at this first brace end face some radiating fins and be located at respectively two fixed blocks at the two ends of this first brace, this two fixed block is attached at this mainboard, this first radiator panel is located at mainboard, and the two ends of this two fixtures strain and each fixture are butt substrate and fixed block respectively.

Compare prior art, this electronic installation compresses this fixture realization by the first radiator the second radiator is fixed on to mainboard, without offering screw, very convenient.

Main element symbol description

Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.

Embodiment

Please refer to Fig. 1 and Fig. 2, the better embodiment of electronic installation of the present invention comprises a mainboard 10, one first radiator 20, one second radiator 30 and two fixtures 40.

This mainboard 10 comprises a central processing unit 12, around some electronic components that are arranged in a row 16 of a side of four fixed legs 14 of this central processing unit 12 and contiguous this central processing unit 12.These electronic components 16 are that Voltage Supply Device provides voltage to this central processing unit 12.

This first radiator 20 comprises a square substrate 22, be vertical at some radiating fins 24 of end face of this substrate 22 and four locks 26 that corresponding these fixed leg 14 ground are arranged in this substrate 22.Two accepting holes 28 are offered in the bottom surface of this substrate 22.

This second radiator 30 comprises one first brace 32, be vertically connected at the second brace 35 of the first brace 32 and be located at respectively two fixed blocks 33 of bottom at the two ends of this first brace 32.The end face of each fixed block 33 is offered a location hole 330.The end face of this first brace 32 is vertically convexly equipped with some radiating fins 34.The outside vertical of the second brace 35 extends to form some radiating fins 38.

Each fixture 40 comprises a coil tension spring 42 and is located at respectively two cylinders 44 at the two ends of this coil tension spring 42.

Please refer to Fig. 3 and Fig. 4, during assembling, this second radiator 30 is placed on this mainboard 10, make the bottom surface of the first brace 32 contact the end face of these electronic components 16, these two fixed blocks, 33 these mainboards 10 of contact.Two cylinders 44 of each fixture 40 are contained in respectively a location hole 330 of this second radiator 30 and an accepting hole 28 of this first radiator 20.These locks 26 are locked respectively to these fixed legs 14, make this two coil tension springs, 42 strains, until the bottom surface of the substrate 22 of this first radiator 20 contacts the end face of this central processing unit 12.Now, the first radiator 20 and the second radiator 30 are fixed on mainboard 10, the bottom surface of the substrate 22 of radiating fin 38 these first radiators 20 of contact that are positioned at the top of this second radiator 30.
