Field of the Invention The present invention relates to a flat heat pipe, a heat pipe type cooling device, and a flat heat pipe suitable for cooling heat-generating electronic components used in portable electronic equipment such as a notebook personal computer. In particular, the present invention relates to a flat heat pipe, a heat pipe type cooling device, and a flat heat pipe manufacturing method which are small, easy to manufacture, excellent in heat conductivity, and easy to attach.

Description of the Related Art Conventionally, a heat pipe in which a condensable fluid is sealed as a working fluid in a metal pipe such as a copper pipe has a thermal conductivity several to several hundred times higher than that of a single metal such as copper or aluminum. Because of its superiority, it is widely used as a cooling element in various electronic devices and heat-related devices.

合させている。The shape of this heat pipe is generally almost a circular pipe, but when it is incorporated in a portable small electronic device such as a notebook computer, the shape of the heat pipe is reduced to reduce the size and weight. A heat pipe having a flat cross section is often used. In the use of such a flat heat pipe, bonding with a heat radiating component (heat generating component) such as a heat sink is performed using an adhesive.

The bonding strength depends on the specifications of the adhesive. In addition, since the adhesive is interposed between the heat radiating component and the flat heat pipe, the contact thermal resistance increases, and the performance as a cooling device may be reduced.
