Abstract: Provided are a heat pipe coolant capable of suppressing deformation of a flat plate-like heat pipe, and a flat plate-like heat pipe. The heat pipe coolant is a coolant enclosed in a flat plate-like heat pipe serving as a heat diffusion plate. The heat pipe coolant includes water and a deformation suppressant that lowers the hardness when the water freezes. The deformation suppressant is 1,4-dioxane or diethylene glycol dimethyl ether. A content of the water is 90 wt % or greater. A content of the deformation suppressant is 0.5 wt % or greater.

Abstract: A heat transport device includes a housing, a wick, and a vapor passage. The housing has a sealed space in which a working fluid is sealed. The wick forms a capillary passage through which a liquid-phase working fluid flows inside the housing. A gas-phase working fluid flows through the vapor passage inside the housing. An outer wall of the housing has a heating element disposing portion on which a heating element is disposed, and a non-disposing portion on which a heating element is not disposed. An internal portion of the housing has a heat receiving portion overlapping with the heating element disposing portion in a thickness direction of the housing and a heat radiating portion overlapping with the non-disposing portion in the thickness direction. Both the wick and the vapor passage are provided to extend over the heat receiving portion and the heat radiating portion.
