Title:
ヒートパイプ構造体、ヒートシンク、ヒートパイプ構造体の製造方法及びヒートシンクの製造方法
Document Type and Number:
Japanese Patent JP6943893
Kind Code:
B2
Abstract:
An object of the present invention is to provide a heat pipe structure excellent in heat transferability from a base block to a heat pipe and excellent in fixing stability of the heat pipe to the base block even if the heat pipe is thermally connected to the base block using caulking means and a heat sink including the heat pipe structure.A heat pipe structure includes a base block including a rear surface part thermally connectable to a heat generating body and a heat pipe including a heat receiving tubular portion fixed to a front surface part of the base block and disposed along an in-plane direction of the base block. The base block has a longitudinal direction and a width direction and includes a recessed part in which the heat receiving tubular portion is accommodated, and a container part of the heat pipe is caulked and fixed in the recessed part and a first metal part containing first metal having a melting point equal to or higher than 130°C and equal to or lower than 400°C and/or a first metal alloy having a melting point equal to or higher than 130°C and equal to or lower than 400°C is formed between the recessed part and an outer surface of the container part.
