Description

Radiator assembly

The invention relates to a heat sink assembly, in particular to a heat sink assembly which utilizes a heat pipe to directly contact a heat source to improve heat transfer efficiency.

Referring to the first to third figures, a conventional heat dissipating device includes a heat pipe a, a fixing base b, two locking springs d, and a heat equalizing plate e. The fixing seat b is provided with a groove c. The heat pipe a is fixed in the groove c of the fixing seat b by solder paste bonding; the two locking springs d are coupled to both sides of the fixing seat b; the heat equalizing plate e is used to heat the heat equalizing plate e Solder paste is disposed on the bottom of the heat pipe a and the fixing base b.

A heat source contact surface is on the same level.

The heat sink assembly of the invention not only can directly transfer the heat of the heat source to the heat transfer effect of the heat pipe, but also reduces the weight of the heat sink device due to the lack of the setting of the heat equalizing plate; The method of adopting Wuxi tightly fits not only reduces the cost, but also makes the processing simpler.

The detailed description of the present invention and the accompanying drawings are to be understood by the accompanying claims .

Referring to the fourth to ninth drawings, a heat sink assembly includes a heat pipe 1, a metal support member 2, and a fixed spring plate 3, wherein: the heat pipe 1 is provided with a first heat source contact surface 11; The support member 2 is respectively provided with a second heat source contact surface 21; and a fixed reed 3, which comprises a heat pipe joint portion 31, preferably a reverse tapered notch, and is matched with a tin-free manner. The heat pipe is combined; the two supporting portions 32 are respectively combined with a metal supporting member 2; and the four fixing portions 33 are fixed on a base 91 provided with a heat source 9; The sheet 3 does not completely cover the heat pipe 1. After the heat pipe 1 is combined with the fixing spring 3, the first heat source contact surface 11 of the heat pipe 1 protrudes from the fixing spring 3, and the metal support 2 is The two heat source contact surfaces 21 are on the same level as the first heat source contact surface of the heat pipe 1.

The heat sink assembly of the present invention directly contacts the second heat source contact surface 21 of the metal support member 2 and the first heat source contact surface 11 of the heat pipe 1 to the surface of the heat source 9 to be dissipated, and then fixes the plurality of screws 8 with a plurality of screws 8 The four fixing portions 33 of the reed 3 are locked on the base 91 provided with the heat source 9; thereby, the heat pipe 1 can directly contact the heat source 9, thereby improving the heat conduction effect, and processing by adopting a tin-free fitting method. It is also more convenient.

In addition, in order to increase the supporting force of the fixing spring 3, a plurality of ribs 34 are preferably disposed between the heat pipe joint portion 31 of the fixing spring 3 and the support portion 32.

In addition, the metal support member 2 can be used not only as a support but also as a function of uniform temperature and heat conduction. Preferably, the metal support member 2 is in contact with the heat pipe 1, and thus the heat pipe 1 can be assisted.

In addition, in order to achieve an optimal heat conduction effect, preferably, the area of the second heat source contact surface 21 of the metal support member 2 and the area of the first heat source contact surface 11 of the heat pipe 1 should be greater than the heat source for heat dissipation. 9 surface.

In addition, the manner in which the fixed reed 3 and the metal support 2 are combined may be combined by means of integral molding or riveting.

In addition, the fixed reed 3 is preferably a stainless steel fixed reed; the metal support 2 is preferably a support member of aluminum, copper or other metal heat conductive material; the top thickness of the fixed reed 3 Preferably, it is controlled within 0.5 mm.

In summary, the present invention can achieve the intended use purpose, and solve the lack of the conventional, and because of the novelty and progress, fully meet the requirements of the invention patent application, and apply according to the patent law, please check and The patent in this case is granted to protect the rights of the inventor.

However, the above description is only a preferred embodiment of the present invention, and thus the scope of the present invention is not limited thereto, and the equivalent techniques and means, etc., which are used in the description of the present invention and the contents of the drawings, are the same. It is included in the scope of the present invention and is combined with Chen Ming.
