Abstract:
A thin and flat type heat pipe with enhanced heat conductivity. Between an upper member 22 having a rectangular area 24b on a lower surface and a lower member 20 having a rectangular area 24a on an upper area are provided intermediate plate members 32, 30. The members 32, 30 are each formed with slits 8, constructing a vapor path extending in a planar direction, communicating with the rectangular areas 24a, 24b of the members 22, 20, respectively. Thus, a sealed space is defined by the slits 8 and the rectangular areas 24a, 24b so that a refrigerant is enclosed in the sealed space. Capillary holes 10 are formed through non-slitted portions of the intermediate plate members 32, 30 so that each capillary hole 10 serves as a capillary path of flow extending vertically to communicate with the rectangular areas 24a, 24b of the members 22, 20.

Abstract:
A small and thin heat pipe 1 with enhanced heat conductivity. Between an upper member 2 having a grid-like upper concave portion 21 on an inside lower surface and a lower member 3 having a grid-like lower concave portion 17 on an inside upper surface are provided intermediate plate members 7 and 8. The members 7, 8 are each formed with multiple vapor diffusion flow paths 10 extending in a planar direction, communicating with the concave portions 21, 17 of the members 2, 3, respectively. Thus, a sealed space is defined therebetween so that a refrigerant is enclosed therein. Capillary flow paths 11 are formed through a portion of the members 7, 8 except where the vapor diffusion flow paths 10 are formed such that the capillary flow paths 11 extend vertically or both vertically and horizontally, communicating with the concave portions 21,17 of the members 2,3.
Abstract:
A multilayered circuit board for a semiconductor chip module includes an underlying board, insulating layers, fixed-potential wiring layers, via holes, and metal layers. The underlying board has a major surface made of a metal material to which a fixed potential is applied. The insulating layers are stacked on the major surface of the underlying board and have wiring layers formed on their surfaces. The fixed-potential wiring layers constitute part of the wiring layers formed on the insulating layers. The via holes are formed below the fixed-potential wiring layers to extend through the insulating layers. The metal layers are filled in the via holes so as to make upper ends be connected to the lower surfaces of the fixed-potential wiring layers. One of the insulating layers in contact with the major surface of the underlying board is formed on the underlying board while the lower end of the metal layer is in contact with the major surface of the underlying board. The other insulating layer formed on the insulating layer in contact with the major surface of the underlying board is stacked while the lower end of the metal layer is in contact with the upper surface of the fixed-potential wiring layer of one insulating layer.
