To improve heat exchange efficiency between heating air and a combustion gas on a combustion type heater.SOLUTION: A combustion type heater 1 includes: a heater case 2 through which heating air flows; and a combustion gas tube 4 through which a combustion gas flows, and exchanges heat between heating air and a combustion gas. The combustion gas tube 4 is disposed in a spiral shape inside the heater case 2. Heating air flows through the heater case 2 so as to face a combustion gas that flows through the combustion gas tube 4.SELECTED DRAWING: Figure 2
【課題】燃焼式ヒータにおいて暖房用空気と燃焼ガスとの熱交換効率を向上させる。【解決手段】燃焼式ヒータ1は、暖房用空気が流れるヒータケース2と、燃焼ガスが流れる燃焼ガスチューブ4とを備え、暖房用空気と燃焼ガスとを熱交換させる。燃焼ガスチューブ4はヒータケース2内に螺旋状に配置されている。そして、燃焼ガスチューブ4内を流れる燃焼ガスと対向するように、ヒータケース2内を暖房用空気が流れる。【選択図】図2
