<p><P>PROBLEM TO BE SOLVED: To secure stable heat exchanging performance by eliminating variation of contact conditions between PTC heaters and electrode plates without complicating a structure in a LPG heating device including a heater unit with the PTC heaters held between the electrode plates. <P>SOLUTION: The LPG heating device having a plurality of heater units 60A having a circumference edge side holding the PTC heaters 61, 61 by the electrode plates 65, 66 surrounded by a frame 62 provided in parallel, and heating LPG by supplying electricity to the PTC heaters 61 through the electrode plates 65, 66, is provided with electrode plate fixing parts having two row of electrode plate fixing parts having a plurality of electrode plate locking claws 621, 622 including locking surfaces abutting on and locking circumference edge side outer surfaces of the electrode plates 65, 66 arranged in a circumference direction on an inner circumference surface of the frame 62 with keeping the locking surfaces in same direction, in a direction that the locking surfaces mutually oppose. Inner surfaces of the electrode plates 65, 66 and an outer surface of the PTC heater 61 are fixed under a close condition by the electrode plate fixing parts. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
