Abstract
A heat source device comprising: a combustion chamber (2) provided between a burner (31) and a heat exchanger (1); an inlet pipe (20) for allowing a fluid to be heated to flow in the heat exchanger (1); an outlet pipe (21) for allowing the fluid to be heated to flow out from the heat exchanger (1); and a winding pipe (27) wound around an outer surface of a peripheral wall of the combustion chamber (2), wherein either the inlet pipe (20) or the outlet pipe (21) has an orifice (91) for throttling a fluid flow path of the fluid to be heated flowing in the inlet pipe (20) or the outlet pipe (21).
Claims3
A heat source device comprising:
- a burner for generating combustion exhaust gas;
- a heat exchanger through which the combustion exhaust gas flows;
- a combustion chamber provided between the burner and the heat exchanger;
- an inlet pipe for allowing a fluid to be heated to flow in the heat exchanger;
- an outlet pipe for allowing the fluid to be heated to flow out from the heat exchanger;
- and
- a winding pipe wound around an outer surface of a peripheral wall of the combustion chamber,
- wherein either the inlet pipe or the outlet pipe has an orifice configured to throttle a fluid flow path of the fluid to be flowing in the inlet pipe or the outlet pipe,
- an upstream end of the winding pipe communicates with an upstream branch provided on an upstream side of the orifice in the inlet pipe or the outlet pipe, and
- a downstream end of the winding pipe communicates with a downstream branch provided on a downstream side of the orifice in the inlet pipe or the outlet pipe.
