<P>PROBLEM TO BE SOLVED: To prevent local heating and boiling in a liquid chamber with a simple constitution, by devising a shape of a return port part. <P>SOLUTION: This heat source device has a sideways arranged can body 16 for forming the liquid chamber 41 for storing a heating medium liquid between an inner cylinder 39 and an outer cylinder 40 and forming a combustion chamber 42 inside this liquid chamber 41, a burner 17 arranged on one end side of the combustion chamber 42 of this can body 16, and a circulating pump for returning the heating medium liquid of the liquid chamber 41 again to the liquid chamber 41 after circulating to a radiator; and is constituted so that the return port part 45 of the liquid chamber 41 is arranged in a lower part on one end part side of the can body 16 near the burner, and a forward opening part 47 of the liquid chamber 41 is arranged on the other end part side of the can body 16. The return port part 45 is composed of a return port pipe 46 having an opening surface X for jetting the heating medium liquid in one direction on one side of the circumferential direction of its inner cylinder 39, by allowing its tip part to approach or abut on the inner cylinder 39 by penetrating through the outer cylinder. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
