<p><P>PROBLEM TO BE SOLVED: To provide a heat exchanger, along with a heat source device, capable of increasing heat transfer efficiency with respect to total heat generated in a heater while suppressing the power consumption of the heater. <P>SOLUTION: A heat source device 1 includes a freezing prevention function for preventing a liquid in piping from freezing and a secondary heat exchanging unit 14 for heating the liquid running through heat receiving pipes 43 and 44 with a combustion gas generated by fuel combustion. The secondary heat exchanging unit 14 includes a case member 15, inlet side headers 20 and 21, outlet side headers 22 and 23, and a heater device 18. The heater device 18 is composed of a heating unit 24 including a heating element 47 and a heat transfer member 48 and a plate 34 having thermal insulating properties and flexibility. The heater device 18 is mounted so as to bridge between the outlet side headers 22 and 23 arranged at high positions and the sidewall surfaces 60 and 61 of the case member 15 with reference to the normal installation state of the heat source device 1. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
