Abstract
A fluid temperature control apparatus performing precise control of the temperature, in which a high sealing performance in a heat transfer chamber is maintained even under a situation of repetitive thermal cycle accompanying the cooling and heating. The fluid temperature control apparatus includes a heat transfer block formed with an inflow port, an outflow port and a concave portion; a heat transfer plate which constitutes the heat transfer chamber by covering the concave portion of the heat transfer block; a holding unit for holding the heat transfer block and the heat transfer plate by using an elastic member so as to prevent plastic deformation of the heat transfer block by means of expansion or contraction of the elastic member following thermal expansion or thermal contraction of the heat transfer block; and temperature controlling unit for performing heat exchange with the fluid via the heat transfer plate.
