Claims

[Scope of Claim for Utility Model Registration] 1. A heat exchange device for a warm air heater in which molded blocks are combined to form a burner chamber heat exchange section and an exhaust chamber inside, which includes a pair of left and right internal heat absorption fins and an external heat exchange section. 1. A heat exchange device for a hot air heater, comprising an integral half-type side block and end blocks provided at the upper and lower portions of the side block. 2. The forming process of the side blocks and end blocks is drawing or extrusion process, and the external heat exchange part formed on the side blocks is an external heat radiation fin or an external heat absorption fin pipe. Heat exchange device for the hot air heater described. 3. The left and right side blocks and the upper and lower end blocks are each formed in the same shape, and each block is integrally or integrally assembled by welding etc. as stated in paragraph 1 of the utility model registration claim. Heat exchange device for hot air heater.
