Abstract: The filter device includes a supply air introducing part, a filter main body part and a discharge part. The supply air introducing part takes in an outside air. The filter main body part includes a ventilation pipe connected to the supply air introducing part to allow the outside air to flow through the ventilation pipe and a filter housing part being equipped with an outflow hole allowing the outside air to flow outside at a position higher than a position of the opening part of the ventilation pipe to separate, from the outside air, a liquid in a liquid state or a state close thereto. The liquid is taken in together with the outside air. The discharge part discharges at least the separated liquid from the filter main body part.

Abstract: A heat exchanging unit exchanges heat between a fluid to be heated and exhaust gas. The heat exchanging unit includes a heat exchange portion, a header portion, and a flow changing portion. The heat exchange portion includes a heat exchange pipe in the interior of which the fluid to be heated flows. The header portion is connected to the heat exchange pipe, the header portion allowing the fluid to be heated to flow from the header portion to the heat exchange pipe or from the heat exchange pipe to the header portion. The flow changing portion changes the state of flow of the exhaust gas introduced into the heat exchange portion.
