Description of the Invention: [Technical Field] The present invention relates to a heat transfer device, and more particularly to a flat plate heat pipe. [Prior Art] Electronic components usually generate a large amount of heat during operation. To ensure proper operation of the electronic components, the heat needs to be dissipated in time. • The electronic components are usually equipped with a heat sink for heat dissipation. The heat sink typically includes a heat absorbing plate and a heat sink fin disposed on the heat absorbing plate. The heat absorbing plate is made of a metal material with good thermal conductivity such as copper or sho, but the metal plate is subject to the limited heat conduction of the material itself, and the right electronic component of the right heat is generated, and the heat resistance is not good enough. Heat dissipation affects the operational stability of electronic components. In order to improve the efficiency of the heat sink, the industry also adopts a cavity in the heat absorbing plate. The cavity is sealed with working fluids such as water and ethanol, and the phase change of the working fluid is used to increase the heat transfer speed. During operation, the working fluid absorbs heat in the heat absorption zone of the heat absorbing plate to reach the heat release zone of the heat absorbing plate, and then liquefies. In order to enable the liquefied working fluid to be grasped to the heat absorbing zone of the heat absorbing plate, the heat absorbing plate sighs a capillary structure around the cavity. The capillary structure is generally classified into three types: powder sintered capillary structure, mesh capillary structure, and groove capillary structure. The liquefied working fluid is returned to the endothermic zone in the capillary structure to participate in the phase change cycle. However, in the process of use, the heat sink of the heat sink 201108921 board is exposed to pressure from the outside and the inside is easy to appear. Yang 'even the capillary structure inside the heat absorbing plate (four), seriously affecting the heat dissipation efficiency and stability of the heat sink Sex.

A heat sink comprising a fin set and a flat heat pipe combined with the fin set, the flat heat pipe comprising a sealed casing and a capillary structure layer attached to an inner surface of the casing, the casing Filled with a certain amount of working fluid, the housing is provided with a support body, the support body includes a plurality of support portions and a plurality of body portions connecting the plurality of support portions, each support portion includes a plurality of alternately arranged and respectively abutting the shell The upper convex portion and the lower concave portion of the opposite side walls of the body, each of the upper convex portions and the adjacent lower concave portion are combined to form a first through hole for providing a passage for the working fluid vapor flow. 201108921 • Compared with the prior art, the flat heat pipe of the radiator of the present invention is provided with a support body which is located in the casing and abuts the capillary layer, and can have capillary structure layers and shells on both sides thereof. The body provides a strong support to prevent the flat heat pipe from deforming under the action of internal and external forces to ensure the flatness of the flat heat pipe. [Embodiment] As shown in Figs. 1 and 2, a heat sink package according to a first embodiment of the present invention includes a fin set 10 and a flat heat pipe 20 combined with the fin set 10. The fin set 10 includes a substrate 12 and a plurality of fins 14 extending upward from the substrate 12. A heat source 30 is in thermal contact with the bottom of the flat heat pipe 20. The flat plate heat pipe 20 includes a sealed casing 22, a capillary structure layer 24 attached to the inner surface of the body 22, and a support body 26 disposed in the capillary structure layer 24. The housing 22 is filled with a stationary working fluid (not labeled) from which the working fluid can flow from the top of the capillary structure layer 24 into the bottom of the capillary structure layer 24. The capillary structure layer 24 is formed from a metal mesh wire.
