Document Type and Number:
WIPO Patent Application WO/2010/032414
Kind Code:
A1
Abstract:
Provided is a coolant heating device which can improve the heat transmission from an external pipe to an internal pipe. The coolant heating device (30) includes: the internal pipe (31) through which coolant flows, the external pipe (32), and an induction heating coil (33). The external pipe (32) surrounds the internal pipe (31) and is made from a magnetic material. The induction heating coil (33) surrounds the external pipe (32) and inductively heats the external pipe (32). A heat transmission agent (43) having a higher thermal conductivity than the air is arranged between the external circumferential surface (31a) of the internal pipe (31) and the internal circumferential surface (32b) of the external pipe (32).
