ABSTRACT:
A temperature regulator has two headers connected to both ends of a heat receiving tube in which gas flows. The heat receiving tube has a heating element at the outer periphery thereof and a mixer accommodated therein to cause turbulent flow of gas passing through the heat receiving tube. The headers each have fins radially attached thereto, thereby ensuring strength of the headers and improving heat exchange efficiency.
