Abstract:
A fluid temperature control apparatus comprising:a block member formed with at least one inflow port and at least one outflow port for fluid, and a concave portion which constitutes a part of a heat transfer chamber for controlling temperature of the fluid by allowing the fluid to pass therethrough; a heat transfer plate which constitutes said heat transfer chamber by covering said concave portion of said block member; holding means for holding said block member and said heat transfer plate such that contact portions thereof come into tight contact with each other, said holding means holding said block member and said heat transfer plate by using an elastic member so as to prevent plastic deformation of said block member by means of expansion and contraction of said elastic member following thermal expansion and thermal contraction of said block member respectively; and temperature controlling means for performing heat exchange with the fluid, which passes through said heat transfer chamber, via said heat transfer plate.
